ETAS simulation models are designed for testing and validating ECUs. They realistically model all significant physical effects for complete vehicle and vehicle component tests.

ETAS provides models for all main vehicle components, such as IC engines, traction batteries, electric motors, and fuel cells. The models can be used individually or as part of a complete vehicle simulation.

Through its LABCAR-MODEL product family, ETAS offers a comprehensive model portfolio. Developers benefit from the vast experience of the Bosch Group, which also allows them to draw on robust, tried-and-tested models. This makes it possible to validate, test, and even calibrate ECU software much more efficiently. LABCAR models contain realistic portrayals of all the relevant physical effects required for reliable testing and are characterized by their real-time capability, high accuracy, and quick, easy parameterization.
