[0001] The present invention relates to a process for the commissioning of an automated drive train of a motor vehicle with at least one gear with at least one switchable gear stage and at least one arranged between the gear and a drive unit, automatically actuated friction clutch, wherein the at least one switching stage and / or the at least one friction clutch by means of at least one Actuator can be operated to and during the start-transmitted in a control unit type of construction specified mechanical quantities of the at least one actuator physical interdependencies of the control of the at least one actuator by means of an arranged outside of the vehicle starting device, the corresponding operation commands to the controller and feedback of the controller on the success of the commissioning receives will be assigned.
[0002] For vehicles with automatic transmissions or automatic friction clutches such as the procedures for placing an initial operation in the factory or re-starting in a garage, according to a Repair are known in which by a commissioning device, such as a diagnostic tool or tester operation signals to the control unit of the motor vehicle for the clutch and forward / or transmission control, so that will be triggered in the motor vehicle appropriate commissioning process, in which the mechanical parameters of actuators physical interdependencies associated . For example, automated with a clutch actuator operated by a friction clutch of the clutch actuator Aktorweg the transmissible through the friction clutch moment in the form of a coupling characteristic, wherein, for example, the touch point of the friction clutch is determined at which the friction clutch begins to transfer torque. At the touch point of the corresponding physical Aktorweg active context in the form of the transmitted torque is assigned. In the case of an automated transmission, the transmission actuator, for example, certain mechanical parameters such as dial-run and / or circuit paths that physical interactions of thresholds such as synchronization, Gangendlagen and the like are allocated. A plurality of separately operated actuators for a friction clutch and the gear can be provided or a single actuator to control several or all functions can be provided. Furthermore, such a start-up procedure for a motor vehicle, for example, with only automated Friction clutch, a motor vehicle for an automated manual transmission with automated friction clutch or a dual-clutch gearbox automated with two actuated part powertrain and two associated with these friction clutches such as in the UK revealed 10 2005 000 888 A1, are proposed.
[0003] In such process, the startup commands, such as for starting up and acquire some clutch or Getriebaktorwege, to the respective controller output, which records the signal responses of sensor devices as mechanical parameters and maps the physical interdependencies in order to obtain a calibration . Here, the success or Failure of the operation documented in the diagnostic device and displayed to the operator when an operation such as by exceeding the permitted limits was not successful. This information is available to the commissioning body and goes in the car later than lost if the vehicle separate from the commissioning body, separated a possibly existing telemetry or the vehicle is stopped. It can therefore draw no conclusions in the motor vehicle for a future misconduct or a failure of the friction clutch or the transmission.
[0004] The invention provides a process for the Commissioning of a friction clutch and / or transmission of a drive train in a motor vehicle to propose in which essential information of the operation in the motor vehicle available.
[0005] The invention provides a process for the commissioning of an automated drive train of a motor vehicle with at least one gear with at least one switchable gear stage and at least one arranged between the gear and a drive unit automatically actuated friction clutch, wherein the at least one switching stage and / or at least one friction clutch by means of at least one actuator can be operated during startup and in a control unit type of construction specified mechanical are sizes of the at least one actuator interdependencies physical assigned shall transmit to the control of the at least one actuator by means of an arranged outside of the vehicle starting device, the corresponding operation commands to the controller and feedback of the controller on receiving the success of the operation, assigned to solve, and in during the commissioning control unit in addition to storing the relationship between the mechanical parameters and the physical interdependencies of the public filings with the commissioning body Rückmeldun gene stored in a permanent memory. By storing the responses in the control unit is a reliable assessment of the commissioning of the friction clutch (s) and / or the transmission or receive at least one actuator possible. In this example directly from the control device such as a reporting defective components such as actuators, friction clutches and / or transmission is possible.
[0006] Here, according caches the inventive concept, the feedback received during the operation in the control unit and before switching off the control device, such as a closure of the motor vehicle and / or separation from the commissioning body in a permanent memory permanently. The permanent memory is made in an advantageous way a non-volatile memory chip such as EEPROM (electrically erasable programmable read only memory reod) was formed.
[0007] Here, a single line of a memory chip to store the necessary feedback may be sufficient. It has, however, especially to keep a possibly required documentation of a history of commissioning carried out proved to be advantageous when multiple responses are stored in a multi-line memory register. Here, the responses are stored sequentially, for example, on a first-in-first-out method, so replace the current feedback from the oldest feedback. Furthermore, for efficient Use of space be provided to assess the feedback regarding its content and only accept messages that are aimed at striking faults or running start operations, are stored.
[0008] Here, the feedback to create a history can be indexed for example by means of a counter, so that successively stored feedback regarding their memory order can be distinguished.
[0009] Further, added to the feedback from other information such as activities, sub-activities or parameters of the routine operation or linked to this be. For example, the feedback is added with the Confirmation conditional mechanical parameters and / or physical operational contexts or to be linked with the feedback. Other parameters such as information on the commissioning implementing agency, will be the date where appropriate, time, identification of the operators, environmental parameters such as temperature and the like, parameters of the vehicle such as mileage, operating and other vehicle assessment criteria such as driver adaptations and the like.
[0010] In a preferred embodiment, the storage of several "negative" feedback to diagnostic requirements in the form of a ring buffer to run, so the real interesting thing is not overwritten by subsequent tests.
