Abstract: A control arrangement for a continuously variable transmission includes an electronic control system and a hydraulic control system. In the hydraulic control system three separate electromechanical control assemblies are used to regulate the pressure in the secondary sheave chamber (to hold the belt tension), the fluid flow to and from the primary sheave chamber (to regulate the CVT ratio), and to control the pressure in the apply line for the clutch chamber. The pump assembly of the hydraulic control system has a first output connection for providing fluid at line (high) pressure in the main line, and a second, low pressure output connection for providing fluid at a low pressure to satisfy the clutch cooling requirements. The high pressure and low pressure systems are essentially independent of each other.

Abstract: A control arrangement for a continuously variable transmission includes an electronic control system and a hydraulic control system. In the hydraulic control system solenoid valves are used in conjunction with fluid control valves to regulate the various fluid pressure levels in the system. A variable displacement pump provides fluid under pressure in the main line. A modulator valve, connected to the main line, provides a controlled low pressure to the various control assemblies. Thus the solenoid valve and associated components can be more economical than in those systems where only the normal line pressure arrangement is used.

Abstract: A method of controlling a shifting operation of a synchro mesh type automatic transmission in a vehicle, such as an automobile. The method includes the steps of (i) detecting the running state of the vehicle, (ii) determining an optimum gear position from the vehicle running condition, (iii) determining if the optimum gear position is higher than a gear position of the transmission, (iv) determining if the engine torque is greater than or equal to a predetermined value and reducing the engine torque below the predetermined value, if the optimum gear position is higher than the gear position of the transmission, (v) disengaging a clutch to disconnect an engine and the transmission, (vi) shifting the transmission to the optimum gear position, and (vii) engaging the clutch. Moreover, the engine torque is reduced before the clutch is released--by reducing the fuel supply to the engine--so that abrupt decelerations and declutching shocks caused by conventional shifting methods are not felt by the driver.

Abstract: A method for controlling an engine using a continuously variable transmission, the method decreases the fuel consumption of the engine in a transient shifting condition. When the operator displaces the accelerator means and the magnitude of the difference between a steady state engine speed, which corresponds to the amount the throttle means of the engine is opened, and a previously detected engine speed differs from a predetermined constant value, the engine speed abruptly increases after a predetermined time elapses and thereafter the engine speed gradually changes to the steady state engine speed. The abrupt increases in the engine speed is a function of a vehicle speed and the amount of the throttle opening.
