this text translated description of DE 102010025089 (A1)
[0001] The invention provides an integrated module relates to the longitudinal guidance of a vehicle, via a lever to activate the brakes of the vehicle and an acceleration of the vehicle can be triggered, to a method for controlling the longitudinal guidance of a vehicle, depending on the actual condition of the vehicle only logically permissible functions of the longitudinal driving vehicles are selected and the vehicles which used the integrated module or procedure be.
[0002] Vehicles include a variety of different controls that are in the longitudinal guidance of the vehicles, that is, to forward or reverse, regardless of the used by the steering wheel controlled lateral control, such as gas, clutch and brake pedals, gear lever in manual shift transmission or automatic transmission, steering wheel or lever different train-pressure switch. These various controls represent isolated modules with the longitudinal guide their interactions cause a large number of possible operating errors can, for example Losfahrversuche without car service or parking brake is activated, simultaneously pressing or confusion of brake and accelerator pedal, especially on vehicles with automatic attempts to stop the vehicle or to remove the key without having set the parking function. In addition, these isolated modules lead to unnecessary duplication of controls, such as the gas pedal and an acceleration button or the brake pedal and delay button when using cruise control systems for speed control, and they require an increased need for space for controls or displays.
[0003] In the past there were attempts at a solution to address the above problems. There are numerous studies for vehicles in which the transverse and longitudinal guide via joysticks. DE 10 2009 006 976 A1 mentioned the possibility of the functions of the steering wheel, brake pedal and accelerator pedal can be fully or partially take over from joysticks, but makes no specific references to the longitudinal control.
[0004] The present invention is therefore the object of an intuitive module for longitudinal guidance of a vehicle, in particular to provide a motor vehicle, reduces the redundancy or cancel, reduce the complexity of the system and also facilitated to environmentally friendly driving.
[0005] This object is solved by the features specified in independent claims.
[0006] Further advantageous embodiments of the present invention are the subject of the dependent claims.
[0007] An integrated module for longitudinal guidance of a vehicle, particularly motor vehicle reduces the number of controls needed for the longitudinal guidance and locations, and contributes to the lowering of complexity and possible misuse. A method for controlling the longitudinal guidance of a vehicle, particularly motor vehicle functions can be contrary to the logic of physics, and is not suitable for the operation of the integrated module.
[0008] The integrated module includes a shift lever to select a vehicle function. This is preferably within reach of the hand of a located on the driver's seat driver, such as aisle or on the dashboard, and can be designed in special technical molds, such as a gear stick, in simplified forms as reduced size joystick, or in more complex forms as a shift lever with ergonomic grip a hand or with additional controls. The shift lever can be moved to different shift positions, which are arranged for example along the path of a gate-shift gate, preferably the boundaries between the switching positions by means of resistors are felt. With the shift lever can also be selected functions, the functions of the control levers of conventional automatic transmission in accordance with, for example, the parking function (P, applying the brake), the neutral function (decoupling of the transmission from the engine and therefore free-running ability), and a driving function (adhesion between the engine and transmission for driving). Preferably, the inventive module is integrated in a vehicle with automatic transmission is used and comprises the function of the gear lever. In addition, the shift of the integrated module combines in an advantageous manner, the function of an accelerator pedal and a brake pedal. This causes the shift lever in a switching position increase the capacity of the vehicle which then takes over the function of the accelerator by increasing the fuel flow in an internal combustion engine or the flow of current in an electric motor. This can take place depending on speed and load situation in vehicles with automatic gear box a suitable choice of the Ganges. Unless added factors such as driving uphill, headwind or ride on the upper performance limit of the engine, due to the increased engine power normally triggered an acceleration of the vehicle so that the following in terms of a single language use not by an increase in engine power, but by an acceleration (of the vehicle is spoken). Comparably the shift lever in a further switching position, a braking of the vehicle by releasing the brakes and thus assumes the function of the brake pedal. The corresponding switching positions can be rest positions or detention positions. In a resting position, the lever is at a point fixed position within the shift lever guide track of the gear shift and institute a set, the driver in their degree no more influenced function, such as detecting the parking brake or the triggering of the neutral position. With a solid hold in the function not only of a point position is exercised, but within a specific area assigned to the shift position along the shift guide path. For example, the degree of braking, so the braking force or the degree of acceleration can be influenced by the driver by the shift lever between the extreme positions of this region along the shift guide path, which is still the switching position for braking or accelerating the shift position assigned to, moved.
[0009] Preferably, are on a shift lever guide track while not switching positions, trigger a forward drive, and switching positions that trigger a reverse. Rather, the integrated module having a control element for switching between forward or reverse, is determined by whether within a gate-rail switching positions for the speeding and refer if necessary to hold the speed to a forward or a reverse. Alternatively, for which forward and reverse two separate shift lever guide tracks, with the shift lever can be pushed by a shift lever guide track via a connecting train to the other shift guide path (for example, with an H-or Y-shaped shift gate). In both embodiments, the select or activate a switch position of reversing be locked when the vehicle is still in significant forward movement, and vice versa.
[0010] Possible switch positions activation of vehicle functions include a shift position for a parked vehicle out of service, the choice of detecting the parking brake, turning off the engine and / or shutting down the triggers for running the necessary vehicle systems (function "PARKEN_AUS"). Another position is a shift position for a parked car in operation, in which the parking brake is set and all of a vehicle driving operation of the necessary systems are activated (feature PARKEN_AN "). Another shift position is a shift position to brake (function "BRAKE"), which may be further subdivided can be. A shift position for braking to a standstill, would ultimately stand cause of the vehicle, and within this switching position, a further division in a switching position for braking to a stop with minimum braking distance (function "emergency braking") or for brakes to a stop without braking distance limitation (feature ANHALT_BREMSE ") is conceivable. In the latter case, the stopping distance would not be critical, the vehicle would come to a preffered ultimately reduce the speed to a stop, the former would trigger an emergency stop. If the switch position for braking until the state is not further subdivided, so that a brake with minimal braking distance, which triggered an emergency stop. The transition in the shift position for braking to a stop at minimum stopping distance is preferably with a clear resistance provided so that the lever can not be pushed accidentally in this switching position, the resistance is low enough to move the shift lever with increased muscle strength, which is used for voluntary or reflex-like emergency braking typically, no causing dangerous delay in the braking process. Other switch positions to brake, a shift position for a mechanical brake (function "MECH_BREMSE) belong, in which the braking action of at least partially by mechanical brakes (for example, discs - or drum brakes) is produced, and a switching position for recuperative braking (function "ÖKO_BREMSE"), in which the energy costs thereof partly or wholly can be fed into a system for energy recovery, although of course both braking modes with sufficiently long activation cause a stoppage of the vehicle. Even when braking functions that are not triggered by the shift position for recuperative braking, an at least partial energy recovery is possible. An example of a further switching position is a shift position for rolling out (function "roll"), in which there is no positive connection between the engine and gearbox and the vehicle slowly by air resistance and friction, if it is not located on a gradient. In another possible switching position for maintain speed (function "GESCHW_HALTEN"), the vehicle would automatically maintain current speed, and it is conceivable that can be considered in this switching position, an external reference of cruise control for the desired speed. In a shift position for acceleration (feature ACCELER ") of the lever as described above would be the driving speed or at least increase the engine power. Possible, a subdivision in a switching position for energy-optimized acceleration (feature ÖKO_BESCHL "), within which, for example, an optimal balance between fuel consumed and obtained additional acceleration there is a shift position for sporty acceleration (feature SPORT_BESCHL "), in which a sub-optimal utilization of the additional fuel consumed in favor of a higher acceleration is taken into account, and a shift position for maximum acceleration (feature MAX_BESCHL"), in the high and highest untapped potential.
[0011] The integrated module can include all of the above switching positions, or which selected representatives. For example, in one designed for extreme energy efficiency of city vehicles with low engine power, the shift position for maximum acceleration omitted so as not to offer an option that goes against the concept of the vehicle and the reserve capacity of the engine is not sufficiently covered. On the other hand, the above-mentioned switching positions by more obvious features are added.
[0012] Among the above-mentioned switching positions, the shift position for a parked vehicle out of service or in operation, the shift position for braking to a stop without braking distance limit, the shift position for rolling out and the shift position for speed must be kept preferably rest positions. The other switch positions are preferably retaining positions, the degree to which the selected function is performed varies within the area assigned to the shift position can be. For example, the degree of acceleration are within the switching position for sporty acceleration be varied within certain limits without a transition in the shift position for energy-optimized acceleration and the shift position for maximum acceleration. are analog, for example, the braking force in the shift position for recuperative braking by moving the shift lever inside its area varies still takes place before a further increase in braking force, a transition in the shift position for a mechanical brake, within which then in turn by moving the shift lever in the corresponding area strength generated by the mechanical brake braking force can be varied can. The switch position for maximum acceleration can be either interpreted as a resting position, which would ensure a shift lever in accordance with this shift position from one to the stop by depressed conventional accelerator, or as a retaining position with the possibility of the degree of acceleration in an upper, but fuel-poor area slightly to vary.
[0013] An accelerator is preferably triggered when the control lever is in a corresponding shift position for acceleration and is within the range corresponding to the front is pushed forward in that direction, and a brake preferably triggered when the shift lever is in an appropriate position for braking and shifting within the corresponding area to the rear, that is pulled in the reverse direction. The area that is formed as a part of a retaining position switch position can be indicated visually and in particular the integrated module such as a range between minimum and maximum brake power brake power, or minimum acceleration and maximum acceleration. Furthermore, can also be provided to give the driver via a force feedback system with haptic feedback on the position of the shift within a range. Here, analogous to increasing the forces that must be spent to create a Accelerator and in particular a brake pedal with your foot in the direction of the stop push through appropriate powers of the further movement of a shift lever in the direction of its maximum position to be in the opposite direction to a switching position associated area. Upon reaching the maximum position then another, clearly perceptible resistance to the transition to the adjacent shift position of the shift would indicate. the shift lever is in a restraining position, he would go when released, preferably automatically in a corresponding rest position. Preferably, this holding for all switching positions to accelerate the shift position for speed, for all switching positions brakes however, the shift position for rolling.
[0014] The switch positions are preferably controlled in a certain order, which follows is an example of an appropriate order, starting at the rear end of the shift guide path, is: Switch position for a parked vehicle out of service, switching position of a parked car in operation, switching position for braking, divided in a switching position for braking to a stop with minimum braking distance (full braking), a shift position for braking to a stop without braking distance limit, a shift position for mechanical brakes and a switching position for recuperative braking, switching position for roll-out; Switch position for maintain speed, and shift position to accelerate divided, a switching position for energy-optimized acceleration, a shift position for sporty acceleration and a shift position for maximum acceleration (the latter concludes with the front end of the shift lever in the direction of travel guide track). Depending on the embodiment, one or more of the positions Schaltpo omitted or additional appropriate switch positions may be added such as a single hard hold for brakes of minimal braking to full braking in automatic energy recovery in appropriate areas. The possibility of skipping of switching positions is provided. For example, it may be necessary to shift from the shift position for maximum acceleration (at one end of the shift guide path) for switching position for braking to a stop with minimum braking distance (near the opposite end of the shift guide path) consider if a sudden obstacle in direction emerges. When skipping can also be made that some or all of the intermediate switching positions can be skipped without resistance, for example triggered by the high rate of lever movement. The function skipped switching positions does not fire. It can also be provided that only Such a switch positions are selected, and displays appropriate to the integrated module with an appropriate label (eg green or red illumination of an icon for a dial-up or not selectable switch position, or visible or invisible symbol or icon for a dial-up Non-selectable switch position, the symbols can play such as the function name, or suitable names, abbreviations, acronyms, logos or icons) that are given the currently given travel situation logically acceptable.
[0015] The integrated module can include other control or display elements. For example, for the setting his speed of travel (eg, cruise control system) or to be observed intervals (eg Distronic system) mounted thumb screws, sliders or input keyboards or on the gear shift lever along the guide tracks.
[0016] According to the scheme, the parameters of the actual condition of the vehicle detects that the motor on or off, and whether the vehicle is at standstill or in motion is. As a minimum requirement for traveling physical logic is determined not to run only one car in the state, but not allowed to ride is, unless explicitly set by the driver, a lack of adhesion between the engine and transmission as well as a dissolved parking brake are. The latter may be necessary if the vehicle is driven in a car wash, where it must be qualified with the engine to free roles, or when towing the vehicle. The appropriate adjustment by the driver can, for example, by pressing a control element that causes the inactivation of the parking brake when the engine or allows to slide the shift lever in the engine off is not normally permitted switching position for roll-out this function is activated. As additional targets are set, that inadmissible when the motor vehicle and a ride in a shutdown of the engine is that for a vehicle in motion is a function a parked vehicle (car function) is inadmissible, and that stop at a vehicle in the state functions such as rolling speed and inadmissible. Taking into account the current parameters for the state of the vehicle and the specifications set is used to determine which vehicle functions currently are allowed under the given logic. In an extended embodiment, these functions in particular those which corresponded to working with the inventive integrated module listed that match by switching positions of the shift initiated functions, so parking function when the engine is in operation or not in operation, braking functions, possibly with divisions, functions of the roll-out and maintain speed, and acceleration capabilities, with or subdivisions. Illegal functions are not activated. Example, found that the vehicle is in motion, then the function of engaging the parking brake when the engine is running or inadmissible and can not be selected or not selected would be at an appropriate positioning of the gearshift lever. Similarly, then turning off the engine would be inadmissible, and such as turning the ignition key, or its removal could be prevented.
[0017] In an embodiment of the method is determined that a shift lever, which currently is a function of Acceleration is to be triggered, which triggers when advancing in the direction of an acceleration or engine performance, while pulling back against the driving direction, a negative acceleration and engine power reduction. The data are based on a forward motion of the vehicle, the link between the shifter and shift directions triggered effect preferably not in reverse changes.
[0018] The above methods are particularly suitable for the control of the novel modules. In particular, can be made that appear to be logical illegal switch positions no icons on the modules. The novel modules and procedures lead to a substantial simplification of the longitudinal guide of a vehicle and eliminate sources of error. They allow a longitudinal guide, regardless of foot pedals, and in particular for disabled drivers without the foot control (for example, after spinal cord injury) is suitable.
[0019] The invention will now be illustrated with examples that should not be construed as limiting, with reference to the accompanying figures. In the figures, identical, functionally identical or similar parts are given the same reference numbers.
[0020] The figures are schematic plan:
[0021] 1 an integrated module with all possible switching positions
[0022] 2 an integrated module with H-shaped shift gate
[0023] 3 is an integrated module of a vehicle with the engine
Example 1:
[0024] An integrated module 1 according 1 includes the gate-web 5 numerous switch positions 3 for a shift lever 2 is a shift position for a parked vehicle out of service 3a, a shift position for a parked vehicle in operating 3b, switching positions on the brakes 3c, with divisions in a switching position for braking to a stop 3c1, which is in turn divided into a switch position for braking to a stop with minimum braking distance 3c1a, and a shift position for keep braking to a stop without braking distance limitation 3c1b, a shift position for mechanical brakes 3c2, a shift position for recuperative braking 3c3, a shift position for rolling out 3D, a shift position for speed 3e, and shift position to accelerate 3f, divided in a switching position for energy-optimized acceleration 3F1, a shift position for sporty acceleration 3F2 and a switching position for maximum acceleration 3F3. Next to the switch positions 3 are symbols for the respective fields for switching positions that reflect in activation of the associated switching position the icon (in 1 to illustrate all the symbols are visible). Between the fields for the symbols and the shift lever guide rail 5 for designed as a fixed stop positions shift positions arrows indicate the range within which the case of a function of the degree of this function by the driver can be changed (eg change of brake force). On the shift lever 2, a control or indicator for additional functions is 6, in this case, a thumbwheel for one-Distronik distance control. The shift lever position 3 within the guide track 5 are based on a forward movement, except as adjusted by the control element for switching between forward or reverse drive 4, a forward drive, failing to reverse. The switch positions 3 according to 1 will be added to Examples 3 to 6 is based.
Example 2:
[0025] An integrated module 1, a gate-rail for forward motion and a compound 5a with a shift lever guide track for reversing 5b, which is an H-shaped shift gate is formed covers. Moving the shift lever 2 in the "V" marked shift guide path for the forward movement 5a, then refer the switching positions 3e and 3f in a forward movement in the lever guide way of reversing 5b ("R") agree to adopt a reverse (2). In 2 is an example of an integrated module 1 shown with a reduced number of switching positions 3rd
Example 3:
[0026] A driver sits in a vehicle whose engine is not running. Accordingly, the shift lever 2 in the shift position for a parked vehicle out of service 3. After inserting the car key posts for the active switch position 3 is shown (3). The only logically permissible alternative switching position, the switch position for a parked vehicle in operating 3b selected and displayed on an illuminated icon. Symbols for other switch position is not displayed. In addition, a symbol "READY" is displayed if a launch vehicle of any technical problems against it (not shown in Figure 3).
Example 4:
[0027] A driver is driving along a road when suddenly a short distance before he rolls a ball between parked cars on the road. He takes a knee-jerk the shift lever 2 from the active switching position hold for speed (3e) through weak resistance which the transitions to the underlying switching positions for roll-3d, for recuperative braking 3c3, for mechanical brakes 3c2 and mark for the brakes to a stop without braking distance limitation 3c1b and will also force feedback forces to the positions of detention for recuperative braking and mechanical braking 3c3 3c2 in his Movement is not hindered. The strong force of its knee-jerk movement, he will also overcome the significant resistance at the transition between the switching position for braking to a stop without braking distance limitation 3c1b, and the shift position for braking to a stop with minimum braking distance 3c1a without loss of time, and triggers the emergency stop.
Example 5:
[0028] A driver leaves the highway to park on a highway parking. Since no other cars in the parking lot, he chooses to delay the strip of highway with the shift lever 2, a shift position for braking to a stop without braking distance limitation 3c1b. The logically invalid switching positions for a parked vehicle out of service for 3a and 3b in a parked car in operation are not eligible, such symbols are not sure on the integrated module. The vehicle comes to a pleasant perceived deceleration to a stop. After the halt of the vehicle was found, the switch positions for a parked vehicle out of service for a parked vehicle 3a and 3b are in operation now allowed, related icons light up so.
Example 6
[0029] The ramp on a highway, a driver puts the shift lever 2 in a switching position for energy-optimized acceleration 3F1 and selected within a range for this position, the lever position, allows him a speedy, but even more energy-optimized acceleration. could be on the acceleration lane, he notes that in the right lane approaching from behind faster vehicles that can not avoid the middle lane of the highway and block its threading into the right lane. The driver then pushes the lever 2 to the end of the shift position for energy-optimized acceleration 3F1, which is shown to him by a resistance which, however, the further movement of the shift lever 2 in the adjacent shift position for sporty acceleration 3F2 not hindered. By now in the shift position for sporty acceleration 3F2 located gear lever, the driver selects two within the relevant fields, a lever position that allows him sufficient acceleration to a safe distance before the acceleration lane approaching vehicles into the right lane motorway to thread. After reaching the desired cruising speed takes the driver's gearshift lever 2 hold in the shift position for speed 3e, whereby he conquers all light resistance, which marks the transition between the switching positions, which hold between the switching position for sporty acceleration 3F2 and the shift position for speed 3e are .
