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 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： A control system is provided for servo hydraulic pressure in an automatic transmission having planetary gear mechanisms. First and second frictional engagement devices, whose servo pressures are reversed in feed/drain relationship between desired two high speed stages, are controlled by a shift valve and a directional control valve. The shift valve is switched by a first solenoid. The directional control valve is interposed in a servo hydraulic pressure feed/drain line communicating the shift valve with the first frictional engagement device and is controlled by a second solenoid. The first and second solenoids are controlled by an electronic control unit in accordance with a shift position detected by a detector, whereby the timings of feed or drain of the servo hydraulic pressures to or from the first and second frictional engagement devices are changed by predetermined relative amounts, respectively.
