摘要： A continuously variable transmission (CVT) for use in a vehicle is controlled such that an actual engine speed Ne is equalized to a desired engine speed No. When a driver's request for a rapid speed change of the vehicle is addressed, a desired engine speed Ns for steady state or the desired engine speed No before the request is detected is defined as a first value Nc1. While the request continues the desired engine speed Ns for steady state which is determined by current values of vehicle running parameters is defined as a second value Nc2. The product B.multidot.(Nc2-Nc1) of a constant B and Nc2 minus Nc1 is calculated and defined as a desired engine speed during the request.

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： In a four wheel drive vehicle, wherein either a state where differential action between front wheels and rear wheels is restricted or a permitted state can be selected, the differential rate is calculated during stable running conditions, and, when the differential rate is greater than or equal to a predetermined value, the restriction of differential action is prohibited. As a result, power circulation can be prevented when there is a difference in effective radius between the front wheels and rear wheels due to, e.g., use of a temper tire, mounting of chains on the tires, or the like.

摘要： A continuously variable transmission (CVT) has input and output pulleys interconnected by a V-belt. The output pulley is actuated by a line pressure. A throttle pressure is increased as the position of an intake throttle valve arranged in an intake path is increased. A transmission-ratio pressure is decreased as the position of the intake throttle valve is increased. The transmission-ratio pressure is decreased in the region of smaller openings of the intake throttle valve more gently than in the region of larger ones. The line pressure is produced in relation to the throttle pressure and the transmission-ratio pressure.
