EPS-in-the-Loop

Develop, test and validate electric power steering systems

Electric power steering (EPS) is a key technology for automated and autonomous driving, whether in passenger cars, trucks, or commercial vehicles. Component-based tests significantly accelerate the development processes of vehicles of all kinds and drive both functional development and calibration forward without the need for full vehicle tests. For this use case, we offer the EPS-in-the-Loop test system.

Your benefits at a glance

Testing the complete EPS ECU

Testing and validation of the real ECU along with the motor responsible for steering assistance

Road-to-lab increases efficiency

What is EPS-in-the-Loop?

EPS:

Stands for electric power steering
Testing of the real electric power steering/power pack (ECU with motor) without the steering column, steering rack, and steering wheel which are simulated models in CarMaker

in-the-Loop:

Refers to both open-loop and closed-loop test procedures for the development and validation of EPS systems
Component-based testing of EPS systems with virtual test driving on the test bench
