    摘要： A hydraulic control system for a vehicular automatic transmission includes a first servomotor, actuated by hydraulic pressure from a hydraulic pressure source, for engaging or releasing frictional engagement elements of the transmission; a second servomotor, actuated by the hydraulic pressure, for applying an engine brake; a manual valve and a shift valve, both connected between the hydraulic pressure source and the first and second servomotors, for controlling the hydraulic pressure; a cut-off valve interposed in a line extending between the manual valve and the shift valve; a solenoid valve for controlling the cut-off valve; and an electronic controller for receiving as inputs vehicular running conditions and a gear-shift mode and for outputting solenoid signals to control the shift valve and the cut-off valve responsive to the inputs. The controller outputs a solenoid signal to the cut-off valve to control communication between the manual valve and the shift valve through the line.

    摘要： A continuously variable transmission system includes a belt type continuously variable transmission unit which, in turn, is composed of a primary pulley and a secondary pulley wherein the torque transmitting direction is switched by torque circulation in changeover between forward and reverse travel. When a low mode is selected in a D range, a somewhat higher hydraulic pressure from a regulator valve is supplied, through a manual valve, to a secondary hydraulic servo, which moves one sheave of the secondary pulley, and a somewhat lower hydraulic pressure from a ratio control valve is supplied to a primary hydraulic servo which moves one sheave of the primary pulley. When the D range is switched to R range by the manual valve, the supplies of the above hydraulic pressures are reversed. With this arrangement, the relative axial forces on the pulleys are changed in switching between forward and reverse travel.

    摘要： A belt type continuously variable transmission (CVT) and a planetary gear unit are combined in a continuously variable transmission system for an automobile to deliver an output from the output shaft in the normal and reverse directions with a neutral position therebetween. A control mechanism with a hydraulic circuit controls hydraulic pressure of primary and secondary hydraulic servos for controlling axial forces applied to respective primary and secondary pulleys of the belt type continuously variable transmission. When an axial force difference is produced between the primary pulley and the secondary pulley, the belt type continuously variable transmission changes its speed corresponding to a torque transmission direction and normal and reverse rotation directions. When axial forces of the primary and secondary pulleys become equal, then the belt type continuously variable transmission self-converges so that the output shaft has zero rotation and is stably held at the neutral position without a driving starter device and without a normal and reverse rotation switching device.

    摘要： An automatic transmission for a vehicle a shift pattern, restricting the movement of a shift lever, including at least an H-shaped portion. When the shift lever has been moved to any shift position of the pattern, a range and a gear ratio which corresponds to the shift position are selected. When the shift lever is released from the shift position in the lowest stage, the gearing is shifted to the ratio which is higher than the lowest stage by one step. When the shift lever is released from the shift position in the highest stage, the gearing is shifted to the ratio which is lower than the maximum stage by one step. When the shift lever is moved to a position intermediate the shift positions, the range and the gear ratio which correspond to the shift position before the movement can be maintained or the automatic transmission range can be established. The switching between the previous stage maintaining function and the automatic transmission drive mode selection function is made by determination of whether or not the driver is operating the shift lever.

    摘要： In an automatic transmission according to the present invention, a coast brake cutoff valve is arranged between a range-pressure-producing manual valve and shift valves and, when changed over, selectively feeds oil to hydraulic engine brake servomotors. An engine brake solenoid valve is on/off controlled by a shifting output signal from a CPU, whereby the coast brake cutoff valve is selectively changed over. A lockout valve is arranged between the coast brake cutoff valve and the manual valve and is connected to one of shifting solenoid valves. The automatic transmission can therefore be operated without trouble even when an electrical problem occurs in the shifting solenoid valves and/or the engine brake solenoid valve.
