Test execution in vehicles (Vehicle-in-the-loop)

You can use TPT for testing vehicles while driving. These are tests where TPT communicates with the vehicle via signals
and parameters and where the driver receives driving commands and other calls to action at the same time.
The measurement data from the tests are assessed automatically by TPT.

Vehicle or driver-in-the-loop testing with TPT

Integration with ETAS INCA

TPT can run INCA remotely. It’s possible to initiate measurements and alter application parameters. Besides scalar parameters, also structured application values like arrays, maps, and curves can be used. The results can be observed on the real system and afterwards assessed automatically.

Integration with Vector CANape

TPT communicates with CANape via interfaces. Access to application parameters, online measurements and diagnosis during the test run are supported. The data can be observed and is used afterwards by TPT for automatic assessment.

Communication via CAN and XCP

TPT can acces CAN and supports XCP over CAN for access of CAN signals, application parameter and measurement of internal signals via A2L mapping.

Integration with CANoe

TPT can execute its test cases via CANoe. CANoe is run remote-controlled by TPT via XiL API.

TPT Autotester: running vehicle tests in parallel

The TPT autotester observes the vehicle while driving automatically. For the selected test case, the driver gets driving commands step by step via intuitive GUI and reading of commands. All other tests are run at the same time in the background.


For example: the gear should be shifted from 1 to 2, and from 2 to 3. While driving to the test track, the gears are shifted. The Autotester recognizes these shifts and marks the tests as being executed. The tests are thus executed by-catch what saves enormous testing time.
