摘要

The control is used for a 4-wheel drive vehicle with a main drive axle with a transverse differential and an auxiliary drive axle driven via a continuously variable drive train. It uses a microprocessor receiving signals representing the wheel velocities of the auxiliary drive axle, to provide setting signals for the continuously variable drive train according to a control function in terms of the detected velocity. Within an initial velocity range the degree of control is enhanced and within a second higher velocity range the control parameter is varied in accordance with the velocity up to a given velocity value, above which it remains constant.
