摘要： In an apparatus for controlling a pulley side-pressure of a belt type continuously variable transmission mechanism provided, in series with a starting clutch, in a transmission of a vehicle having a function of stopping engine idling so that an engine is automatically stopped, if the vehicle start-up is controlled from the state of engine stopping in an ordinary way in which the pulley side-pressure is determined by that belt transmission torque corresponding to an output torque of the engine which is obtained by the rotational speed and the negative suction pressure of the engine, the pulley side-pressure becomes excessive by wrong judgement that the engine output torque is large, because the negative suction pressure is small at the beginning of the engine starting. The durability then deteriorates and the specific fuel consumption becomes poor. As a solution, at a vehicle start-up from the state of engine stopping, a belt transmission torque corresponding to that transmission torque of the starting clutch which is obtained by the engaging force of the starting clutch is compared with a belt transmission torque corresponding to the engine output. The pulley side-pressure is each controlled based on that transmission torque of the drive pulley corresponding to the smaller belt transmission torque and on the transmission torque of the driven pulley.

摘要： A control apparatus for a continuously variable transmission of a vehicle is provided for switching the transmission from a continuously variable transmission mode to a stepped transmission mode without giving any discomfort to the driver, and for appropriately responding to a request for acceleration from the operator during the stepped transmission mode. The control apparatus comprises an ECU for setting a target transmission ratio in accordance with the detected operating condition of the vehicle, controlling the transmission ratio of the continuously variable transmission to reach the set target transmission ratio, and switching the transmission mode between a CVT mode and an AT mode. When the transmission mode is switched from the CVT mode to the AT mode, the ECU sets the target transmission ratio to a transmission ratio in the CVT mode immediately before the switching. Subsequently, when the engine rotational speed reaches an upper limit rotational speed, the ECU sets the target transmission ratio to a transmission ratio on a high speed side such that the engine rotational speed falls to an up-shift rotational speed.

摘要： An electronic control unit ECU controls a shift thrust Ft applied to a variable width drive pulley through a control valve CV and makes the rotational speed Ne of the engine follow a target engine rotational speed Neo to vary the speed change ratio of a continuously variable transmission CVT. In this control, the shift thrust Ft is achieved as sum of a proportional term P and an integral term I, where the proportional term P is determined on the basis of the deviation DNe of the engine rotational speed Ne from the target engine rotational speed Neo, and the integral term I is determined as cumulative sum of the deviation. When the throttle of the engine is closed, the integral term is set larger than when the throttle is open.

摘要： After the engine rotational speed Ne has become below a reference rotaional speed Neo, which is lower than an idling rotational speed of the engine, and after the pressure PL of oil passages 103a and 103b has begun to decrease, for a predetermined time, the currents supplied to electromagnetic valves 45 and 46 are adjusted to generate, in each electromagnetic valve, a second biasing force electromagnetically in a magnitude that can supplement a decrease in a third biasing force which is generated by the back pressure led through an oil passage 107 and 108, respectively, and which decreases as the pressure of the oil passages 103a and 103b decreases. After the above metioned predetermined time has elapsed, the currents supplied to the eletromagnetic valves 45 and 46 are set almost to zero.

摘要： An automatic transmission comprises a metal V-belt mechanism 10, which changes the speed ratio of the rotational output from an engine ENG, a forward/reverse direction change mechanism 20, which switches the rotational direction of the ratio-change mechanism, and a forward clutch 30, which actuates the switching operation of the rotational direction performed by the forward/reverse direction-change mechanism. A control system for this transmission comprises a regulator valve 50, which generates a line pressure, a manual valve 80, which is operated in correspondence to the shift lever and switches the supply of the line pressure to the forward clutch, and a drive-range sensor 105, which detects the operation of the manual valve. When the movement of the manual valve to a position where the line pressure is to be supplied to the forward clutch is detected by the drive-range sensor 105, the line pressure, which is adjusted by the regulator valve, is lowered for a predetermined time period.
