    摘要： A control apparatus and method control a torque of an engine coupled to an input shaft of an automatic transmission during a shift by that automatic transmission. A torque-down control by which the engine torque is decreased by a predetermined amount is performed, a torque-restore control starting point at which time torque-restore control is to be started is determined, and the torque-restore control so as to gradually restore the engine torque to a value before the torque-down control was performed is started at the torque-restore control starting point. The torque-restore control starting point is determined according to a dynamic model which simulates behavior of the automatic transmission over time from start of the torque-down control, so that a rotational speed of the input shaft of the automatic transmission at a target point substantially matches a target speed.

    摘要： A hydraulic control apparatus includes two oil flow control valves (30, 32) each provided with a supply control portion (36, 38, 52, 54) for controlling an oil supply from a pressurized oil source, and a discharge control portion (40, 42, 56, 58) for controlling connection with a discharge passage. One of those oil flow control valves supplies/discharges oil to/from one of hydraulic chambers (22, 24) that are oppositely formed in a hydraulic servo mechanism. An operation direction of the hydraulic servo mechanism is performed by operating one of the oil flow control valves. The other operation direction of the hydraulic servo mechansim is performed by operating the other oil flow control valve.

    摘要： In a power transmission system for transmitting power of an engine to a load, a planetary gear mechanism provided in parallel to a speed variator combines torque conveyed from the engine with torque conveyed from a motor generator in a state such that their torque ratio equals a predetermined ratio, and transmits the combined torque to a driven wheel. When performing power transmission between the engine and the driven wheel via both the speed variator and the planetary gear mechanism, power distribution between the power conveyed to the speed variator and the power conveyed to the planetary gear mechanism can be actively controlled by adjusting the torque of the motor generator. As a result, the speed variator capacity can be reduced while enhancing power transmission efficiency.
