Hardware-in-the-Loop (HiL) testing systems comprise an essential contribution to quality assurance during the early phases of ECU development. By simulating the model components known as Driver-Vehicle-Environment (DVE), they facilitate the testing of the functions or diagnostic behavior of ECUs in the laboratory. This makes it possible to run reproducible and comprehensive tests of virtually any driving situation with the added benefit of extensive test coverage through automation – entirely without hazard to driver and vehicle.
LABCAR is part of the standardized ETAS tool family, which covers all stages of the V-model. Tests may therefore be run on a given model (Model-in-the-Loop, MiL), executed on existing software (Software-in-the-Loop, SiL), on a connected physical ECU (Hardware-in-the-Loop, HiL), or may involve additional measuring and calibration (M&C) steps affecting the data calibration onboard the ECU.
For years, LABCAR has been successfully used to integrate and test control and diagnostic functions in numerous production projects, e.g.:
- Engine management
- Transmission management
- Antilock braking systems (ABS)
- Electronic stability programs (ESP)
- Electro-hydraulic brake systems (EHB)
- Adaptive cruise control (ACC)
- Active front steering
- Seat and window control
