Abstract
The subject-matter is a motor vehicle having a drive system which acts on the wheels of an axle via an automatic limited-slip differential (ASD) in dependence on the driving speed and on the slip of the driving wheels, rotational-speed sensors being provided for each vehicle wheel and a control logic circuit being provided which processes the signals of the rotational-speed sensors and other signals to form control signals for connecting and disconnecting the limited-slip differential, taking into consideration the driving-dynamic aspects in the respective driving condition, the limited-slip differential being combined with a wheel slip control (ASR) which exclusively acts on the drive torque of the vehicle engine in order to ensure a high measure of traction and driving stability overall with low expenditure.
