Automotive MEMS sensors
Restraint systems

In restraint systems, Bosch MEMS sensors detect abrupt vehicle deceleration. This information is the essential input for triggering the release of the vehicle's airbags.
The sensor data are processed by the central airbag ECU, which activates adequate restraint systems according to the classification and severity of the accident.
The sensors can be installed in the ECU or as satellite sensors in the periphery of the vehicle (front, side and rear).
