Abstract
An electrical regulating device, particularly for a speed control device for motor vehicles, with a servomotor, a rotatably mounted setting element which actuates the position or adjustment actuator, the setting element being in operative connection with the servomotor via an electro-magnetic coupling, and a monitoring stage for the mechanical functioning of the coupling. The monitoring stage contains a unit for recognizing the restoring speed of the setting element or the adjustment actuator, a unit for comparison of the actual resetting speed with a pregiven reference value and a unit for production of a signal upon an unsafe deviation of the actual resetting speed from the reference value.
