Abstract: A system for controlling a friction clutch of a motor vehicle having a continuously variable transmission. The system has an actuator for shifting a clutch plate of the clutch. Vehicle start intention is detected in accordance with a first depression of an accelerator pedal. In response to the vehicle start intention, the actuator operates to shift the clutch plate to a partial engagement position at a maximum speed. The clutch plate is kept at the position and then the clutch plate is shifted from the partial engagement position to an entire engagement position, when the transmission is upshifted.

Abstract: A continuously variable belt drive transmission has a torque converter with a lockup clutch. Transmission ratio of the transmission starts to change in accordance with driving conditions of a vehicle, and the lockup clutch is engaged in accordance with driving conditions of the vehicle. A start signal for starting of the changing of the transmission ratio is produced in accordance with driving conditions, and a lockup signal for engaging of the lockup clutch is produced in accordance with driving conditions. In response to the start signal and to the lockup signal the change of the transmission ratio and engaging of the lockup clutch are performed at the same time.

Abstract: A control system for a continuously variable transmission has a transmission ratio control valve having a spool for controlling oil supplied to a cylinder of a drive pulley to change the transmission ratio. The transmission ratio control valve has chamber at both ends of the spool. By controlling the flow rate of oil supplied to the chambers in accordance with a desired transmission ratio, the spool is shifted, so that the rate of change of the transmission ratio is controlled. The transmission ratio changing rate is corrected by the rate of change of the desired transmission ratio. Two coefficients representative of the degree of throttle opening and a physical condition such as viscosity are also generated to correct the transmission ratio changing rate.

Abstract: A control system for a continuously variable transmission for a motor vehicle has a line pressure control valve and a transmission ratio control valve, each having a spool for controlling oil supplied to a cylinder of a pulley. The transmission ratio control valve has chambers at both ends of the spool. The flow rate of oil supplied to the chambers is controlled by an on-off valve at duty ratio in accordance with a desired transmission ratio so that the spool is shifted, so that the transmission ratio changing speed is controlled. The duty ratio is corrected by line pressure, so that the transmission ratio is controlled in accordance with the line pressure.
