摘要： System and method for controlling a continuously variable transmission having a pair of variable-diameter pulleys disposed on input and output shafts, and a corresponding pair of hydraulic cylinders to change effective diameters of the pulleys. A speed ratio control valve assembly is used to control flows of a fluid to and from one of the cylinders. The control valve assembly is selectively placed in one of three states consisting of a first state for feeding the fluid to the one cylinder, a second state for discharging the fluid from the one cylinder, and a third state for restricting the flow to or from the one cylinder. The first and third states are alternately established while a ratio of an operating time in the first state to that in the third state is changed, for controlling a rate of flow of the fluid into the one cylinder, and the second and third states are alternately established while a ratio of operating time in the second state to that in the third state is changed, for controlling a rate of flow of the fluid from the one cylinder, whereby the speed ratio of the transmission is continuously varied by the one cylinder under control of the speed-ratio control valve assembly.

摘要： 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.

摘要： A method is provided for controlling an engine using a continuously variable transmission whereby the fuel consumption of the engine is decreased. When an accelerator of the engine is displaced, first and second desired engine speeds are determined for steady state conditions before and after the displacement of the accelerator, respectively. The difference between the two desired engine speeds is calculated and compared with a predetermined value. If the difference between the desired engine speeds is smaller than the predetermined value, the actual engine speed is adjusted to gradually approach the second desired engine speed. If the difference between the two desired engine speeds is larger than the predetermined value, the actual engine speed is immediately adjusted to a transient value and is then adjusted to approach the new desired engine speed gradually.

摘要： A hydraulic control system for a continuously variable transmission having a cylinder for changing the effective diameter of a pulley to control a speed ratio of the transmission. The control system comprises a spool valve assembly communicating with the cylinder to control the supply and discharge flows of a fluid to and from the cylinder. The valve assembly comprises a shift-speed control valve unit for controlling a rate of variation in the speed ratio of the transmission. The shift-speed control valve unit has only two discharge ports associated with the fluid discharge from the cylinder. The shift-speed control valve unit may take the form of a spool valve having a spool axially movable to open and close the ports to permit and restrict the fluid flows through supply and discharge conduits communicating with the ports and the cylinder. The spool may only partially open the corresponding port to permit the fluid flow therethrough for supplying or discharging the fluid. The valve assembly may comprise a shift-direction switching valve unit for changing the direction in which the speed ratio is varied. The switching valve unit has only two discharge ports associated with the fluid discharge from the cylinder.

摘要： An apparatus for controlling an continuously variable transmission (CVT) used for a power transmission system of a vehicle. The CVT is controlled such that an actual engine speed becomes a desired engine speed. The desired engine speed is set as a function of running parameter such as intake throttle position. When the CVT is controlled in the same way as at the steady state of the vehicle at the acceleration of the vehicle, the acceleration performance is degraded. Thus, according to the present invention, the speed ratio of the CVT is reduced when the acceleration of the vehicle is small, in spite of the requisition of the vehicle acceleration. As a result, satisfactory drivability is attained.
