The peripheral acceleration sensor (PAS) from Bosch provides information on direction and level of impact by measuring accelerations during a crash in one spatial axis. In addition, Bosch provides a two-channel peripheral acceleration sensor, the PAS enhanced, that can record longitudinal and lateral vehicle accelerations. The optional installation of this sensor can further improve the performance of the airbag system as it provides additional acceleration information on the longitudinal direction of the vehicle.
Peripheral acceleration sensors can be installed in the vehicle in addition to acceleration sensors already integrated in the airbag control unit in order to improve performance and evaluation of the restraint system’s triggering decision.
The peripheral acceleration sensors are a main component of occupant and pedestrian protection systems.
