A vehicle electrical system includes at least one battery, at least one fan and a device for detecting a critical state in the vehicle electrical system. The fan is activated when a critical state of the vehicle electrical system is detected. In this context, use is made of the fan's ability to store mechanical energy in the form of inertias. The fan operates in a regenerative manner and electrically feeds the mechanically stored energy back into the on-board electrical system.

Method and device for stabilizing an on-board electrical system of a vehicle electrical system

A device and a method for measuring torque for an electromechanical steering system comprises a steering means that is connected in a driving manner to a steering mechanism via a torsion rod which is provided with an input shaft part () and an output shaft part (), an electric servomotor for driving the steering mechanism, the driving activity by the servomotor causing a relative rotational displacement between the input shaft part () and the output shaft part (), a sensor unit () for detecting a steering angle (d), a sensor unit () for detecting a rotor angle of the servomotor (), and a virtual torque sensor () in which a steering moment (&#x3c4;) is determined from the steering angle (d) and the rotor angle.
