Problem to be solved – Create a single point crash sensor which measures accelerations in three directions and rotations about three axes and does not need self-testing.
Solution – Build the sensor around a mass produced MEMS IMU (Inertial Measurement Unit) with drifting errors corrected using GNSS satellite signals.
Features – Can detect crashes from any direction, provided structural coupling is available, as well as rollovers about any axis in one small very inexpensive device.
Benefits – One device measures crashes from any direction and rollovers about any axis for selective deployment of any or all of the vehicle’s airbags. Very significant system cost reduction.
