Abstract
A crash sensor system for a vehicle capable of operating in an autonomous mode includes an electronic control unit (ECU) having a processor circuit. The ECU triggers an occupant restraint system of the vehicle in the event of a severe impact event with the vehicle. Satellite sensors are electrically connected to the ECU and are mounted at the front end, the rear end, the right side and the left side of the vehicle near or on an outer surface thereof to detect low severity impact event with the vehicle that does not cause activation of the occupant restraint system. The processor circuit executes an algorithm to confirm, via data from the plurality of satellite sensors, whether the low severity impact event with the vehicle occurred and if so, the ECU triggers a brake controller and a steering controller to cause the vehicle, while in the autonomous mode, to pull over and stop.
