Validation of Pre-Crash Systems with Vehicle Hardware-in-the-Loop Experiments

Reversible passive safety restraint effectiveness is improved through use of a Pre-Crash System (PCS), which is activated prior to a collision by an environment sensor. A PCS must undergo a wide range of (near-) collision scenario testing in order to meet very high reliability and safety requirements. The authors discuss new Vehicle Hardware-in-the-Loop (VEHIL) experiment methodology for PCS validation. A Hardware-in-the-Loop (HIL) environment, where only target and host vehicle relative motion is reproduced, can host PCS-equipped vehicle collision-free testing by using a VEHIL laboratory. Safer, cheaper, and more efficient PCS validation is possible through accurate and repeatable VEHIL experiments. A prototype PCS demonstrates VEHIL's added value. Detecting a pre-cash situation and bringing the occupant into optimal crash position through a reversible belt retractor is done through a radar system in this system.
