Abstract
An apparatus that both prevents excessive engine speed and satisfies a driver's requested drive torque. A control apparatus provides torque control to a hybrid electric vehicle and uses a calculated engine speed final target, and engine speed temporary target, which may 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 based on the calculated engine power final target. Engine torque is controlled based on the calculated engine operating point target (especially the engine torque final target). In addition, motor generators are controlled to operate in power running mode or regenerating mode, based on the calculated engine operating point target and electrical power target.
