The invention relates to a method for detecting the point of force exertion on a vehicle. The aim of the invention is to solve the technical problem which consists of detecting the vehicle underbody as the source of shocks and to prevent faulty release of the at least one airbag. According to the inventive method, at least three sensors are arranged in the vehicle at a distance from each other. The moment in time when forces are exerted is measured by means of said sensors. The differences in running time between the measured signals are measured by at least two independent pairs of sensors and the point of force exertion is calculated on the basis of the at least two differences in running time, the speed of sound and the co-ordinates of the sensor positions. |
