Definitions
- a diagnosis in motor vehicles or for motor vehicles in the sense of the present invention is to be understood in particular to mean the checking of predetermined functionalities of the motor vehicle or the checking of predetermined characteristic values which have an influence on predetermined functionalities.
- diagnosis is not intended to limit the invention.
- the voltage limit value can in each case have the same value or different values, it being provided in the case of different values that the specific voltage limit value depends on predetermined characteristic values or diagnostic routines or diagnostic requirements or the like.
- test device is in particular an electronic device external to the vehicle, which can be connected to the electronic control device in a wireless or wired manner.
- a test device is designed as a so-called hand-held tester.
- the motor vehicle to be diagnosed has a clutch device and a transmission device.
- the instantaneous voltage supply value can be compared with the limit value in particular in the control device or in the test device.
- the voltage level of this supply voltage is assessed in the test device, or the supply voltage of the control device is compared with a predetermined limit value, and a decision is then made as to whether a diagnostic request is carried out or not.
- control software is transferred from a test device to the electronic control device.
- the deletion of the control software after the diagnosis has been carried out can be initiated by the test device or by the control device or by the diagnostic software stored in the control device and to be deleted.
- initiated is to be understood in particular to mean that the execution of the diagnostic algorithm is triggered by means of a command from the test device, while the algorithm itself or the diagnostic routine is effected and controlled by means of the software temporarily stored in the control device.
- predetermined diagnostic results are displayed to the test device.
- the diagnostic software prevents the motor vehicle from being operated or being operated in normal operation. It is further preferred that the diagnostic software enables normal operation of the motor vehicle only with a corresponding, clear warning, which can be carried out, for example, by an acoustic or optical signal or a signal which can be perceived in some other way.
- the diagnostic software can prevent input and output into a CAN bus system or prevent starter release.
- the diagnostic software has the effect that a diagnostic routine or a diagnostic algorithm can only be carried out if predetermined operating parameters are given. For example, without the invention being restricted thereby, it can be provided that a diagnostic routine or a diagnostic algorithm can only be carried out when the vehicle speed is zero and / or the engine speed is zero.
- At least one predetermined commissioning routine is or must be carried out after the diagnosis has been completed.
- This requirement can be brought about by the diagnostic software, for example. Without the invention being restricted thereby, this can be, for example, such that the diagnostic software has the effect that normal operation of the motor vehicle is not possible as long as a commissioning routine has not been carried out after the diagnosis has been completed.
- the displacement measuring device detects positions and / or changes in displacement of a movably arranged component.
- the incremental sensor is particularly preferably designed as a Hall sensor or has a Hall sensor.
- the movably arranged component is moved back and forth at least once as part of the diagnostic routine between two extreme positions.
- Such an extreme position is preferably an end stop.
- the method for diagnosing the position measuring device is preferably intended for position measuring devices which are assigned to actuators, these actuators not being operated during the diagnosis in an operating mode “position control” in which predetermined positions are controlled in accordance with routines provided for normal operation.
- signals or data can be between an electronic Control device of the motor vehicle and a test device external to the vehicle can be carried out via a CAN bus system or via a K-Line or in some other way.
- a method for carrying out a diagnosis in motor vehicles in which an electronic test device is brought into signal connection with an electronic control device in the context of the diagnosis, signals or data being transmitted between the test device and the control device via an interface.
- This interface has a protocol page and an application page.
- the protocol side and the application side of the interface are assigned to different modules.
- the protocol page is preferably a protocol handler that translates diagnostic commands transmitted from the test device in the direction of the control device.
- the application side in particular converts the diagnostic commands or the translated diagnostic commands into diagnostic functionalities.
- the data array on the application side has data that are received by the control device (received data) or sent to the control device.
- the data array on the application side has data that are provided or sent by the control device (sent data).
- the data array on the protocol side has data that are received by the control device or sent to the control device (received data Data).
- the data array on the protocol side particularly preferably has data which are sent by the control device (sent data), in particular in the direction of the test device.
- the protocol side only has write access to the received data.
- the application side only has write access to the sent data.
- a diagnostic request or a transmission protocol is sent via the interface to the electronic control unit as part of a diagnosis to be carried out, the transmission protocol or the corresponding signal being translated in the interface and then using the application page on the basis of the translated protocol or Signals that the diagnostic commands are converted into functionality.
- the diagnostic results are provided on the application side and then translated by the protocol side in order to be sent to the electronic test device.
- the application side and / or the protocol side has a status byte which controls the timing or the timing of the diagnosis.
- the object is further achieved by a method according to claim 5.
- a method for operating a motor vehicle is provided in particular, by means of which the motor vehicle can be set in motion with limited driving functionalities before the start-up of an automated clutch device.
- the torque transmitted and / or transmissible by the clutch device is increased in a ramp shape when the motor vehicle is in accordance with a driver's request should be set in motion on its own initiative.
- the activation is carried out by means of a diagnostic command.
- an error is set in an electronic control unit of the motor vehicle or in a memory of this electronic control unit when the diagnostic command activates the method with which the motor vehicle can be operated with limited driving functionalities.
- This error entry indicates that the motor vehicle is in an operating state in which it can be operated with at least limited driving functionalities without the automated clutch device having already been started up.
- the error entry is withdrawn and / or the method for operating the motor vehicle is terminated with at least limited driving functionalities when the automated coupling device of this motor vehicle has been started up and has ended.
- the increase in the clutch torque is effected within the control unit by corresponding master cylinder path specifications.
- the master cylinder is loaded by a drive, such as an electric motor and / or the like, and in turn loads a slave cylinder, which causes the opening status of the clutch to be changed.
- the drivability with at least limited driving functionalities is activated during the manufacture or assembly of the motor vehicle by mounting the actuator or during the assembly of the actuator.
- driveability with at least limited driving functionalities is brought about by a command sent by an electronic test device. This can particularly preferably take place in the context of a service case in a workshop.
