摘要： PROBLEM TO BE SOLVED: To provide a hydraulic control device capable of avoiding occurrence of a rapid deceleration state in a belt type continuously-variable transmission without adding a new solenoid valve. SOLUTION: The hydraulic control device is equipped with a fail-safe valve 305 capable of switching hydraulic pressure to be supplied to a primary pulley 41 between output hydraulic pressure of a gearshift hydraulic pressure control valve 301 and hydraulic pressure different from the output hydraulic pressure. The fail-safe valve 305 is switched to a fail position for supplying the different hydraulic pressure to the primary pulley 41 when there is possibility that a rapid deceleration state will occur, and is otherwise switched to a normal position for supplying the output hydraulic pressure of the gearshift hydraulic pressure control valve 301 to the primary pulley 41. The switchover of the fail-safe valve 305 is controlled by control hydraulic pressure of an ON-OFF solenoid (SL) 204 and control hydraulic pressure of a duty solenoid (DSU) 203.

摘要： PURPOSE:To reduce uncomfortableness of speed change when a shift lever is switched to a D range from a manual speed change position. CONSTITUTION:It is judged whether speed change is generated or not (step S60) when a shift lever is switched to the D range position from the manual speed change position, and a temporarily map for suppressing any speed change except at least necessary time is set instead of a normal speed change map for the D range in the case the speed change is generated (step 70). The speed is not changed as possible (step S90, 100) until the throttle opening or vehicle speed is varied, and it is set to the D range when the throttle opening or the vehicle speed is varied, (step 140), and then the speed change is processed based on the normal map of the D range (step 150).

摘要： PURPOSE:To pysically sense a torque change sufficiently by providing a hydraulic circuit to attain respective speed change stages by means of speed change output signals of a control device and a regulating means to make a speed change response in the case of manual speed change larger than in the case of automatic speed change. CONSTITUTION:Though a hydraulic circuit to operate a transmission is used in the same as usual, in order to prevent a speed change shock in the case of speed change, a delay angle quantity is set, and the ignition timing is delayed, and engine torque is reduced. In the case of manual speed change mode, a speed change control device 31 judges that torque reduction control is required in the case of speed change transitional time. The torque reduction control is carried out by reducing the delay angle quantity sent to an engine control device through a torque reduction input/output processing circuit of a driving circuit 39. Thereby, since the delay angle quantity of an engine is reduced and the engine torque is increased, a speed change response caused by engagement with frictional engaging elements can be made large, so that a torque change can physically sensed.

摘要： PURPOSE:To eliminate a difference or the like between a driver's expected shift stage and an actually attained shift stage by measuring the time for a shift lever to be at the neutral position in a manual gear shift mode, and applying such a means as attaining a forward travel range when the measured time exceeds the prescribed value. CONSTITUTION:In this automatic transmission, a shift lever is moved over the range of a shift pattern comprising a range position for an automatic gear change mode, a shift position for a manual gear shift mode, and neutral positions for respective types of mode. In this case, a sensor or the like 37 detects that the shift lever is moved to each position. Also, a control device 31 outputs a gear change signal, according to a range and a gear selected with the shift lever. Furthermore, an actuator 40 is driven to attain each gear, according to the gear change signal. On the other hand, a timer measures a time for the shift lever to stay at a neutral position in the manual gear shift mode. Also, the gear selected immediately before is maintained until the measured time exceeds the prescribed value, and a forward travel range is attained when the prescribed value is exceeded.

摘要： PURPOSE:To surely make an engine brake effective at a gear shift stage where the engine brake is required. CONSTITUTION:A check ball valve 700 is arranged so as to bypass a coast brake cut-off valve 500, which is controlled by a third solenoid valve S3 to selectively supply D range pressure to a third brake B3, so that L range pressure may be supplied to the third brake B3 via this check ball valve 700. Even when a failure is caused in the third solenoid valve S3 and the coast brake cut-off valve 500, the third brake B3 is surely engaged to enhance its durability.
