Abstract

A vehicle upfront sensor is described that has a cavity and a sensing element therein. A collision is detected as a function of the deformation of the cavity. The sensing element may be designed as a pressure or temperature sensor, the cavity then being largely closed, so that an adiabatic pressure or temperature increase is measurable.
