Date Mar. 31, 1994.In a drive arrangement of a motor vehicle in which the wheels of the motor vehicle are driven by separate electric motors and the electric motors are powered via a d.c. voltage intermediate circuit by a generator arrangement driven by an internal combustion engine, the speed of the internal combustion engine and individual wheels is sensed by speed sensing circuits which respond to pulse signals of commutator circuits of the generator arrangement and electric motors. The commutator circuits generate the pulse signals depending on position transmitters which are arranged at the generator arrangement and at the electric motors. In this way, the speeds can be sensed with great accuracy exclusively on the basis of already existing components of the drive arrangement. In particular, the speed sensing means cooperate with an antilock braking system (ABS) and a drive slip regulating system (ASR).
