Abstract

The invention refers to a system and a method for differential lock control in a vehicle 2 comprising a differential gear 18 between left and right powered wheels 8, 10 and a differential lock 26 which, when engaged, locks together the left and right powered wheels 8, 10. Differential lock control operation is coordinated with brake operation by the fact that a control unit 30 which controls both the brake regulator 36 for regulation of braking force to the drive powered wheels 8, 10, and an operating unit 31 for connecting and disconnecting the differential lock 26, is arranged to effect, when a differential lock control 28 is operated to disengage the differential lock 26, alternate braking of left and right powered wheels 8, 10 at the same time as the differential lock 26 is being disengaged, thereby relieving the differential lock 26 of load so that it becomes torque-free and hence ensuring that the differential lock 26 becomes completely disengaged.
