摘要： An automatic transmission, for a vehicle with an engine, includes a hydraulic fluid pump which supplies pressurized hydraulic fluid. The engine load is detected, and the pump output is controlled so as to increase with increase of the load on the engine. If the pump is one whose output per one revolution of its input member is variable, then its output may be thus controlled by increasing its output per one revolution along with increase in engine load. And, if the pump is a variable capacity type vane type hydraulic fluid pump the output of which per one revolution of its input member is controlled by varying the eccentric position of a controlling member thereof, then its output per one revolution may be thus controlled by detecting the eccentric position of the controlling member using a sensor, and by varying this eccentric position in a feedback manner to achieve a target eccentric position which is determined to give a pump output per one revolution varying as an increasing function of engine load. Alternatively, if the pump is a fixed capacity type electrically driven type hydraulic fluid pump the output of which per one revolution of its input member is substantially constant, then its output may be thus controlled by varying the rotation speed of its input member as an increasing function of engine load. A system for implementing this method is also disclosed.

摘要： A hybrid vehicle having a function for reducing the pumping loss. When the shift is in the reverse position, when an appliance is to be driven while the vehicle is in its stopped state and when the electric motor alone is able to drive the vehicle, the fuel supply to the internal combustion engine is cut off and one of the following is performed: the engine's throttle is widely opened; the engine is decompressing by opening the intake and exhaust valves; or the engine is decompressed by closing the intake valve while opening the exhaust valve. In such a manner, the pumping loss in the internal combustion engine can be reduced. Thus, the drag on the electric motor which would ordinarily be caused by stopping the internal combustion engine can be prevented without the provision of a one-way clutch or other equipment between the internal combustion engine and the electric motor.

摘要： A vehicle automatic transmission includes a torque converter which has a rotational power output member, and also includes a gear transmission mechanism. This gear transmission mechanism includes; a friction engaging mechanism; first and second rotational power input members; a first clutch which selectively engages the torque converter rotational power output member to the first rotational power input member; and a second clutch which selectively engages the torque converter rotational power output member to the second rotational power input member. When the torque converter rotational power output member is rotating the first rotational power input member via the first clutch, the gear transmission mechanism is enabled to provide its first speed stage, while, when the torque converter rotational power output member is rotating the second rotational power input member via the second clutch, the gear transmission mechanism is enabled to provide a speed stage other than its the first speed stage in cooperation with the engagement operation of the friction engaging mechanism. The rotational speed of the rotational power output member of the torque converter is detected, when the first clutch is disengaged and the second clutch is engaged, by taking it as being the rotational speed of the second rotational power input member of the gear transmission mechanism. A system is also disclosed for performing the method.

摘要： In a four wheel drive power transmission system for a vehicle, a power distribution device receives rotational power from an engine and provides rotational power to the combination of the front wheels and also to the combination of the rear wheels, and is controllable either to provide differential action between the front wheels combination and the rear wheels combination, or for this differential action to be at least partially inhibited by torque transmission. This slippage control device includes: a subsystem which estimates the torque being input to the power distribution device for four wheel drive from the transmission mechanism; and a subsystem which provides differential action inhibition of the power distribution device according to the thus estimated value of the torque being input to it from the transmission mechanism. The method of operation of this device is also described.

An idling control system for the transmission includes a first mechanism for engaging the forward clutch selectively either to a maximum amount or to an intermediate amount substantially lower than the maximum amount; a second mechanism for engaging the brake, when the forward clutch is thus engaged to the intermediate amount by the first mechanism; and a third mechanism for, when the automatic transmission is being operated in a forward driving mode, the vehicle is substantially stationary, and the engine is in substantially idling condition, actuating the first mechanism thus to engage the forward clutch to the intermediate amount and the second mechanism thus to engage the brake. Thereby, rolling of the vehicle backwards down a hill while waiting in the stopped condition with the engine idling is positively prevented, and starting off of the vehicle is also facilitated.

When the transmission is in a forward driving mode, the vehicle is substantially stationary, the engine is substantially idling, and the braking system is applied, the third mechanism engages the forward clutch to the intermediate amount and engages the brake. Thereafter, if the application of the braking system is terminated, it engages the forward clutch to the maximum amount and continues engaging the brake, or, if the engine ceases to be in substantially idling condition, it engages the forward clutch to the maximum amount and disengages the brake. Thereby, rolling of the vehicle backwards down a hill while waiting in the stopped condition with the engine idling is positively prevented, and mild traffic creep is also provided.
