Hardware in the loop systems integrate an ECU with a simulated ECU environment. The ECU environment includes all components of the vehicle system, i.e. set-point generators, sensors, actuators, as well as components for diagnostics. The use of HiL systems, or lab vehicles, allows ECUs to be tested early on
in a virtual test environment without real environment components.
HiL technology has reached a good maturity level. However, the total cost of ownership for HiL technology remains high. Therefore, efficiency and cost reduction are important goals for the development of LABCAR HiL systems. Reliable operation and good usability are other key requirements.
