Definitions

  • the invention relates to a method for automated commissioning of a transmission of a motor vehicle, in which the geometry of the transmission is checked with regard to at least one parameter stored in a control unit.
  • the commissioning commands used which are transmitted by the external control unit, are intended for use during initial commissioning in a gearbox as well as in the field at the vehicle manufacturer or in a workshop. Among other things, it is checked whether the determined gear positions lie within defined limits. The limits are adjusted so that they accept worn, but still functioning transmission systems. To ensure that gearboxes with borderline components are not delivered to the end customer, the tester usually checks the determined gearbox parameters. If the parameters are too close to the permissible limits for the system, the gearbox will be sorted out although the commissioning has been completed successfully. Such a test is particularly due to cycle time restrictions or due to a used command generator, for example, if a built-in control unit controls the startup, for example by means of an automatic sequence to make only with enormous effort.
  • the invention is therefore based on the object, a method for automated
  • the object is achieved in that a diagnostic command is sent to control the transmission, wherein the diagnostic command contains a tolerance indication for the at least one parameter.
  • the tolerance data By taking into account the tolerance data during commissioning of the gearbox, the limit values for the wear-prone gear end positions are reduced. This avoids that a gearbox with borderline components leaves the production plant. In addition, a premature failure of the transmission is prevented at the end customer. Since no additional data must be evaluated when evaluating the at least one parameter, but an existing diagnosis command is merely supplemented by an indication, the evaluation is simplified by means of an automatic procedure of commissioning and reduces the cost of the evaluation.
  • the diagnostic command contains a startup command for activating a startup program of the transmission. This has the advantage that not only the commissioning command but at the same time the tolerance information for at least one parameter are transmitted to the transmission control unit with a single command. This shortens the control program.
  • the tolerance specification of the at least one parameter is included
  • Such a design implements the tolerance specification in a stand-alone statement, which guarantees that this tolerance specification is actually taken into account in the further processing of the commands.
  • the diagnostic command containing the tolerance specification of the at least one parameter is sent prior to the diagnostic command containing the commissioning command for activating the commissioning program of the transmission. This ensures that the tolerance information is already stored and processed in the gearbox control unit before the commissioning command has arrived, and that this is then taken into account during commissioning in all cases.
  • the tolerance indication is given as an absolute value for the at least one
  • the tolerance is specified as a percentage of the stored in the transmission control unit parameters. This percentage indication allows the use of such a diagnostic command in transmission control units with different control programs, which depend on the functionality of the gear to be checked. Thus, by means of only one diagnostic command, the tolerance information can be flexibly adapted to the parameters provided for the transmission to be tested.
  • the tolerance specifications for the at least one parameter for a first commissioning of the transmission are selected differently from the tolerance specifications for the at least one parameter for a sequence commissioning. It is taken into account that when the transmission is operated at the end customer wears the gearbox and thus change the current values of the parameters, but still ensures that the values are still within the limits that are given in a new commissioning.
  • the tolerance data for the at least one parameter for a first commissioning of the transmission are narrower than the tolerance information for the at least one parameter for a subsequent commissioning. This ensures during commissioning that a failure of the gearbox shortly after delivery does not take place at the end customer. During follow-up commissioning, the change in the parameter due to wear due to wear during use of the gearbox is taken into account.
  • the diagnostic command contains information as to whether the commissioning of the transmission is a first commissioning or a subsequent commissioning.
  • the transmission control unit receives the information about which tolerance information should be taken into account when testing the transmission.
  • FIG. 1 schematic representation of a test stand with connected gear
  • Figure 2 a schematic diagram of the installed in a motor vehicle transmission.
  • the transmission 1 produced in a production facility is a dual-clutch transmission which has two clutch actuators 2, 3.
  • the transmission 1 comprises a transmission actuator 4.
  • the thus formed transmission 1 is connected to a test bench 5, which includes a test stand internal transmission control unit 6, which is connected to a test bench PC 7.
  • the test stand-internal gearbox control unit 6 is connected via a separate CAN bus 8 with the two clutch actuators 2, 3.
  • a method for evaluating the parameters of the transmission 1 during commissioning of the transmission 1 is to be considered.
  • a diagnostic command is sent from the test bench PC 7 to the on-board transmission control unit 6.
  • the diagnostic command includes a tolerance of the parameter to be tested, which is sent to the transmission 1 via the communication line 9 simultaneously with the command for putting the transmission 1 into operation.
  • the transmission for example, a required gear.
  • the geometric parameter which is traversed by the transmission 1 during this gear setting, is measured and sent back to the transmission control unit 6.
  • the transmission control unit 6 compares this parameter with the stored parameter, which is acted upon by the transmitted tolerance information and thus determines whether the transmission is functional. If the tolerances are exceeded by the determined parameter, the transmission 1 is estimated to be inoperative, which is signaled by an error message.
  • the tolerance specification can be an absolute value for the respective parameter. However, the tolerance indication can also be determined as a percentage of the particular parameter stored in the transmission control unit 6. For each parameter, a minimum value and a maximum value are specified by means of the tolerance information.
  • the parameters underlying the commissioning routines are transmitted from the test bench-internal control unit 6 to one of the clutch actuators 2 or 3 and temporarily stored there in a non-volatile memory unit 10. Since the clutch actuator 2, 3 is permanently installed with the transmission 1, this is used together with the transmission 1 at the vehicle manufacturer in the motor vehicle. After installation of the transmission 1 in the motor vehicle, the transmission 1, as shown in Figure 2, connected to a new transmission control unit 15, which is installed in the motor vehicle. In this case, the parameters from the non-volatile memory unit 10 of one of the two clutch actuators 2, 3 are transmitted to a non-volatile memory unit 14 of the transmission control unit 15.
  • a non-volatile memory unit is understood to mean a memory unit which does not lose its memory content even when the power supply to the memory unit is switched off or fails. The memory contents are thus available again after power has been restored to the memory unit. Examples of such non-volatile memory units are EEPROMs.
  • the schematic representation shown in Figure 2 illustrates the arrangement of the transmission 1 in a motor vehicle.
  • the clutch actuators 2, 3 are connected to the transmission control unit 15 via a separate communication line 8 designed as a CAN bus.
  • the commissioning command containing the tolerance data is output by another control device installed in the motor vehicle, preferably an engine control unit 16, to the transmission control unit 15, which triggers the commissioning of the transmission 1.
  • the diagnostic command for transmitting the tolerance information contains information as to whether the transmission is an initial startup or a follow-up startup, so that the correspondingly correct tolerance information is used as the basis for checking the transmission 1.
  • the further procedure of commissioning corresponds to the procedure described in connection with FIG.
  • tolerance information is carried out both during commissioning of the transmission 1 at a first commissioning in the factory or at a follow-up commissioning of the built-in the motor vehicle transmission 1 in a workshop.
  • tighter tolerances are stored in the transmission control unit 6 during initial commissioning, as they are used to check the parameters in an already used transmission 1.
  • the method described is advantageous, in particular, during initial commissioning in the gearbox or vehicle plant, since the limits for the wear-endped gear end positions are reduced. This avoids that a gearbox with borderline components leaves the production plant.
