Abstract
A control circuit for motor vehicles serves to prevent an undesirable spinning of a driven vehicle wheel. The following components are provided for this purpose: a first angular speed transmitter to detect the speed of at least one non-driven vehicle wheel, a second angular speed transmitter to detect the speed of at least one driven vehicle wheel, a microcomputer connected via subcircuits to the two angular speed transmitters, and an actuating device to actuate at least one clutch or brake in the gear train between the vehicle engine and the driven vehicle wheel or wheels which is controlled by the microcomputer as a function of the differential between the speeds detected at any time by the two angular speed transmitters.
