Abstract

A modified antilock system/wheel slip control system arrangement is provided whose logic provides the use of the wheel slip control system valve as the actuating valve for the compressed-air cylinder used for engaging the differential lock of a limited-slip differential. The wheel slip control system valve or actuating valve will become operative, when a wheel slip control system control operation is started or when a coefficient of adhesion difference is recognized between the right and the left driving wheel of the vehicle at a pressure below a pressure threshold which engages the differential lock, to carry out the conventional wheel slip control system brake control. Once a maximum speed is reached and the adhesion difference is minimized, the wheel slip control system valve is fully opened to engage the differential lock.
