Crash sensor systems utilizing vehicular inertial properties

An arrangement for a vehicle, comprising:

• an electronic crash sensor system, comprising:
• at least one inertial measurement device arranged on the vehicle to measure an inertial property of the vehicle;
• a processor that incorporates or executes a crash sensing algorithm that determines whether the vehicle is sensing a crash based on the inertial property measured by each of said at least one inertial measurement device;
• and
• a positioning system arranged on the vehicle to provide a position of said positioning system that is considered as a position of the vehicle,
• the inertial property measured by each of said at least one inertial measurement device being modified based on the position provided by said positioning system and then provided to said crash sensing algorithm such that said crash sensing algorithm determines whether the vehicle is sensing a crash based on the modified inertial property measured by each of said at least one inertial measurement device,
• whereby self-testing of said at least one inertial measurement device is not performed;
• and
• at least one occupant protection device arranged on the vehicle, each of said at least one occupant protection device being coupled to said crash sensor system and being actuated based on the determination by said crash sensing algorithm whether the vehicle is sensing a crash.
