Abstract
In a continuously variable speed transmission having a hydraulic pump, a hydraulic motor, a hydraulic closed circuit hydraulically connecting the pump with the motor, a control apparatus has a slip sensor for detecting slip of the driving wheels and a hydraulic control apparatus for lowering hydraulic pressure in the hydraulic closed circuit in accordance with magnitude of the slip of the wheels in such a way that the driving force of the driving wheels is reduced so as to be less than a slip limit force, the slip of the driving wheels being increased when the driving force applied to the driving wheels exceeds the slip limit force.
