摘要： A torque applied to a one-way clutch when a first motor generator and second motor generator are operated in a motor generator drive mode is restrained or prevented from becoming excessively high by setting a first motor generator sharing ratio in response to a driving torque target for the vehicle, by controlling operation of the first motor generator in response to a first motor generator first sharing ratio when vehicle vibrations due to cogging torque are likely to take place, and by reducing the torque from the first motor generator when the driving torque target is large. Torque applied to the one-way clutch which otherwise would become excessively high immediately after engine shutdown, is restrained or prevented by reducing the torque from the first motor generator in response to a second motor generator second sharing ratio when engine downtime is short.

摘要： An upper rotational speed limit NengUL and a lower rotational speed limit NengLL of an engine operation prohibition area are set from an upper rotational speed limit Nmg2UL and a lower rotational speed limit Nmg2LL of a motor operation predetermined prohibition area of a second motor generator. When an engine speed target Nengt, calculated from a preset target operating line, lies in the engine operation prohibition area, the engine operating point target is corrected so that the second motor generator rotational speed target Nmg2t lies outside the motor operation prohibition area. When the engine speed target Nengt is greater than or equal to a change-direction engine speed NengCD at which direction of shift to/from an allowable range of engine operation is changed, the engine speed Neng is increased. When the engine speed target Nengt is less than the change-direction engine speed NengCD, the engine speed Neng is decreased.

摘要： An arrangement which prevents excessive engine speed, satisfies a driver's requested torque and protects a battery from overvoltage. A control apparatus provides a torque control to a hybrid electric vehicle, and calculates an engine speed final target so that an engine speed temporary target does not exceed an upper limit. In addition, the control recalculates an engine operating point target based on the calculated engine speed final target, and calculates an engine power final target based on the recalculated engine operating point target. An electrical power target is calculated and may not exceed an upper limit for battery charging and an upper limit for battery discharging. Engine torque is controlled based on the calculated engine operating point target (especially the engine torque final target). Motor generators are controlled to operate based on the calculated engine operating point target and electrical power target.
