Abstract
A control system for a hybrid transmission of a motor vehicle comprises a vehicle speed sensor and a control unit. In the control unit, a deceleration is calculated. When the deceleration is greater than the predetermined deceleration value under a condition where the vehicle speed is less than a predetermined vehicle speed value, a switch is effected from a torque delivery path through a continuously variable transmission mechanism to a torque delivery path through a gearing mechanism. Thus, there occurs no slip between a V-belt and a driver pulley in the continuously variable mechanism upon acceleration immediately after rapid deceleration.
