Abstract
A device and a method, which, upon triggering of the restraint devices via a control device, allow a systematic testing of the triggering characteristics of restraint devices in a motor vehicle under conditions as realistic as possible. For that purpose, the device includes an ambiency simulator, connectable to the control device, for stipulating defined peripheral states, an acceleration device for accelerating the control device, a detector for recording the triggering characteristics of the restraint devices in response to acceleration of the control device, and an evaluator for evaluating the recorded triggering characteristics. In accordance with the method, the control device is programmed for a particular constellation of restraint devices. A defined peripheral state is predefined for the control device thus programmed with the aid of an ambiency simulator. The control device is then accelerated, in this manner provoking a triggering of the restraint devices. Concurrently, the triggering characteristics of the restraint devices, given the current peripheral state, are recorded and evaluated.
