The single tool you need for automotive virtual testing

Powertrain calibration challenges

Automotive virtual testing

To help you overcome these challenges, we developed dedicated simulation solutions for virtual testing based on modern x-in-the-loop framework. xCAR is the cornerstone of our continuous x-in-the-loop process (see figure below), ranging from the design stages (purely virtual) to road tests (fully real) and introducing, step by step, the right share of virtualization for every stage of the development process. For more information about FEV and our solutions, please click here.

xCAR ensures a continuity throughout the different levels of virtualization.

engine in the loop testing


Example from the xCAR Engine-in-the-loop application used to validate transferability and reproducibility between real chassis dyno tests and a virtual chassis dyno tests performed on an engine test bench:

Use case description:
On the Engine-in-the-loop test bench, the virtual and the real world come together to create a collaborative system. xCAR allows these worlds to communicate with each other. It receives the measurements from the test bench via the automation system and transmits the simulated instructions to the bench. For example, in the case of an EiL test bench setup, the automation system sends the engine brake torque measurement signal to xCAR, which then returns the pedal and speed instructions for controlling the engine based on the applied models.
