The present arrangement provides a method for monitoring the performance reliability of a control unit and/or at least one sensor of a safety device for the protection of vehicle occupants, comprising the steps that a negative acceleration or velocity caused by an impact, in particular, be recorded; a value for the impact severity be derived from the recorded acceleration or velocity; and the value for the impact severity be compared to a predefined threshold value. If the value for the impact severity exceeds the predefined threshold value, an error-function signal will be output, which indicates that the proper functioning can no longer be ensured for the control unit and/or for at least one sensor. The present arrangement also relates to a diagnostic device for such a method.

Method for monitoring the performance reliability of a control unit and diagnostic device

A method and a device for operating a vehicle allow a torque of the vehicle during operation of the vehicle to be measured. A torsional angle at at least one drive shaft of the vehicle is measured, and the torque transmitted via the at least one drive shaft is ascertained as a function of the measured torsional angle.

Method and device for operating a vehicle

A method and a device for deploying a restraint system, which avoids false deployments at the least possible expense by using an acceleration sensor arrangement that includes two sensitivity axes oriented in different directions. An acceleration measured with respect to one of the two sensitivity axes is used for a plausibility check of a deployment decision, which is determined from an acceleration measured with respect to the other sensitivity axis. A trigger signal is only generated if a deployment decision signal and a plausibility signal are present at the inputs of an AND logic circuit at the same time.

Method and device for deploying a retaining system

The invention is based on a method and system for regulation and/or control of an automobile chassis where between the vehicle body and at least one wheel there is at least one actuator actuated by actuation signals for exertion of forces between the vehicle and the at least one wheel. At least parts of the actuation signals are so formed that the vertical movements of the vehicle body will be damped inertially. According to the invention, at least parts of the actuation signals (Fij) are so formed that the damping takes place dependent on the magnitude of the vertical velocity (Zaij') of the vehicle body.
