Abstract
A motor vehicle has a continuously variable belt-drive automatic transmission, an automatic clutch provided between the engine and the automatic transmission, a hydraulic control system and a hydraulic circuit including the oil pump for controlling the transmission. A wheel lock signal is produced when the deceleration of the wheel speed is so large that the wheels may be locked. In response to the wheel lock signal, a clutch release signal is produced when the engine speed is lower than a predetermined low speed. In response to the clutch release signal, the automatic clutch is released and the engine speed is increased, thereby maintaining sufficient output of the oil pump.
