A unit for triggering a safety device in a motor vehicle 10 to protect an occupant of the vehicle when the vehicle impacts with an object 20, is configured to actuate the safety device only if the total stiffness or rigidity between the vehicle 10 and impacting object 20 exceeds a predetermined value. The unit may incorporate a calculating arrangement to calculate stiffness from two or more parameters. Further, the triggering unit may measure another parameter as a function of measured conditions, and compare this to a threshold. |
