Drive control apparatus and method for providing a drive control to a hybrid electric vehicle, and hybrid electric vehicle
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.
