摘要： A lockup clutch of an automatic transmission is controlled so that no shock is produced while the vehicle is running within a predetermined gear stage. The automatic transmission includes a fluid coupling; a lockup clutch provided in the fluid coupling; a shift selector for selecting a range; a vehicle speed sensor for detecting vehicle speed, and a throttle opening sensor for detecting throttle opening. A control unit determines a gear stage in accordance with the selected range, the vehicle speed and the throttle opening, decides a shift, produces a shifting output signal, decides ON or OFF for the lockup clutch in accordance with the selected range, the vehicle speed and the throttle opening, and produces a lockup ON/OFF output signal. An oil pressure circuit actuates solenoid valves in response to the shifting output signal and the lockup ON/OFF output signal of the control unit. The solenoid valves, in turn, control engagement and release of frictional engagement elements to achieve the decided gear stage and control engagement and release of the lockup clutch. The control unit includes, stored in memory, a lockup diagram set with an ON/OFF hysteresis area; a comparator for deciding whether or not the vehicle speed and the throttle opening, at the time of a shifting output signal is produced, are within the ON/OFF hysteresis area of the lockup diagram; and a lockup output signal generator for turning the lockup output ON if the vehicle speed and the throttle opening are within the ON/OFF hysteresis area when the shifting output signal is produced.

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.

摘要： A continuously variable transmission is switchable between the low and high modes by changing engagement between two clutches. A sensor shoe which moves in association with a movable sheave of a primary pulley is provided with an indent and a protrusion formed at different locations on the sensor shoe. In addition, indents are formed on a spool of a low-high control valve. An interlock rod is provided between the sensor shoe and the low-high control valve. In a predetermined pulley-ratio region in the low and high modes, for example, on a low pulley-ratio side, as the movable sheave moves to the O/D side a base end of the interlock rod rides on the upper surface of the sensor shoe while its opposite end is engaged within one of the indents, thus mechanically locking the low-high control valve. In this way, switching between the low and high modes due to selective engagement of the low and high clutches can be inhibited.

摘要： When a driver depresses an accelerator pedal to request a shift such as a downshift or the like, a maximum shift target changing rate (shift speed) of a CVT having a belt-type continuously variable shift apparatus is set based on the shift inertia of the CVT and the like. An assist torque is set by subtracting the normal torque of an internal combustion engine from a torque needed to achieve the maximum shift target changing rate. The assist torque and the torque outputtable from an electric motor based on the characteristic of the motor are compared. If the assist torque is greater than the motor torque, the target changing rate is restricted by an assist possible rate based on the ratio between the assist torque and the motor torque. The shift of the CVT is controlled by the target changing rate (shift speed). Thus, the apparatus allows a quick speed by assisting with a motor torque and, in a case where the assist torque from the motor is insufficient in quantity, allows a shift at a speed in accordance with the case, thereby resolving the degradation of acceleration feel caused by the shift inertia of the CVT.

摘要： An infinitely variable transmission has a gear neutral (GN) point and serves as an output member by torque circulation. When a pulley ratio thereof is within a predetermined range from the GN point, a coasting state occurs which may hinder smooth torque transmission based on the transmission efficiency and generate a great engine braking effect (failure in the transmission resulting from the coasting state) based on a large gear ratio. When the pulley ratio assumes a predetermined value that may cause failure in transmission resulting from the coasting state, upon release of the accelerator pedal, an electronic throttle system performs control such that the engine outputs a predetermined torque. Thus a positive driving state is always established. In this state, the continuously variable transmission (CVT) is shifted in the upshift direction to escape rapidly from a range defined by the pulley ratio of the predetermined value.

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.
