Abstract

A motor vehicle test device and a motor vehicle test method are described. The motor vehicle test device includes a control unit for controlling a predefined test sequence; an operator interface device; and at least one measuring device for measuring at least one vehicle parameter. The motor vehicle test device has a vehicle communication interface and diagnosis software. The control device is developed in such a way that it is able to communicate with at least one control unit of the motor vehicle via the vehicle communication interface.

Claims

1-11. -11. (canceled)

12. A motor vehicle test device, comprising:

a control unit to control a predefined test sequence;

an operator interface device for the control unit;

at least one measuring device to measure at least one vehicle parameter; and

a vehicle communication interface and diagnosis software, the control unit being configured to communicate with at least one control device of the motor vehicle via the vehicle communication interface.

13. The motor vehicle test device as recited in claim 12, wherein the control unit is configured to signal at least one predefined test state of the vehicle parameter.

14. The motor vehicle test device as recited in claim 12, wherein the control unit is configured in such a way that, in response to a signaled test state, the control unit displays a readiness for a communication between the control unit and the control device of the motor vehicle at the operator interface device and makes the communication directly activatable by an operator.

15. The motor vehicle test device as recited in claim 14, wherein the control unit is configured in such a way that the control unit is able to at least one of:

i) read out status information from the control device of the motor vehicle when the communication is activated by the user, or activate simple functions or complex function sequences in the control device of the motor vehicle and implements a calibration procedure in the control device of the motor vehicle.

16. The motor vehicle test device as recited in claim 12, wherein the control unit is configured in such a way that the control unit is able to automatically activate a readiness for a communication between the control unit and the control device of the motor vehicle in response to a signaled vehicle test state.

17. The motor vehicle test device as recited in claim 16, wherein the control unit is configured in such a way that the control unit is able to activate simple functions or complex function sequences in the control device during an automatically activated communication including implementing a calibration procedure in the control device.

18. The motor vehicle test device as recited in claim 17, wherein the measuring device is configured to measure vehicle geometry including at least one of a steering angle and wheel toe.

19. The motor vehicle test device as recited in claim 18, wherein the control device of the motor vehicle is an ESP control device having a steering angle sensor, and the calibration procedure implements a calibration of the steering angle sensor according to the signaled test state.

20. The motor vehicle test device as recited in claim 17, wherein the control unit is configured in such a way that the control unit automatically terminates the calibration in response to a not signaled vehicle testing state.

21. A motor vehicle test method, comprising:

measuring at least one vehicle parameter using a measuring device of a motor vehicle test device;

signaling a predefined test state of the vehicle parameter from the measuring device to a control unit of the motor vehicle test device; and

in response to the signal, displaying a readiness for a communication between the control unit and a control device of the motor vehicle on an operator interface device of the motor vehicle test device, and making the communication directly activatable by an operator.

22. A motor vehicle test method, comprising:

measuring at least one vehicle parameter using a measuring device of a motor vehicle test device;

signaling a predefined test state of the vehicle parameter from the measuring device to a control unit of the motor vehicle test device; and

in response to the signal, automatically activating a communication between the control unit and a control device of the motor vehicle.
