Method for operating lock of lock differential in motor car during shift operation of gearbox, involves changing braking or drive torque to wheel to produce load change, and braking or accelerating wheel relative to another wheel

摘要

The method involves automatically changing braking or drive torque to a wheel to produce load change at a lock differential (3). The wheel is automatically braked or accelerated relative to another wheel in a transverse differential. A position of a lock is monitored by a sensor (6). A control device (1) is connected with an actuator (4) of a brake assembly and/or an engine control (5). A longitudinal differential is relieved, and a lock mechanism is moved into a desired position by difference in speed between front and rear axles of a four-wheel driven vehicle. An independent claim is also included for a control device for operating a lock.
