Abstract
A system tests the functionality of a sensor device which is formed by way of at least one sensor element and is connected to a first evaluation unit in order to generate a signal indicating an impact. A second evaluation unit that is connected to the sensor device is provided for testing the functionality of the sensor device. The evaluation units are connected to a central control unit so as to trigger a pedestrian protecting device while being synchronized in such a way that the evaluation units trigger the sensor device in a time-multiplexing mode of operation.
