Crash Detection
Satellite crash sensors are located on the periphery (i.e., front and sides) of an automobile to provide early detection of an impact. Acceleration sensors dominate the market as pressure sensors are currently limited to use in a vehicle’s front doors. The sensor information is transmitted to the central electronics control unit (ECU) where the microcontroller determines whether and which airbags to deploy as a result of an impact.
