Abstract

A device and a method, respectively, are proposed to detect side collisions, in which a temperature sensor is located in a motor-vehicle side section. In case of a side collision, the temperature sensor measures the short-term adiabatic temperature increase and a control device detects a side collision as a function of the measured temperature increase and the temperature gradient. A triggering decision is made by plausibility testing using an acceleration sensor.
