Abstract
A control apparatus for a hybrid vehicle computes estimated energy and external charge energy. The estimated energy is required to drive a vehicle to travel a planned travel route and an EV priority mode, in which drive power for the vehicle is generated with priority by a motor/generator by supplying electric power from a battery to the motor/generator. The external charge energy is supplied from an electric power source. The control apparatus checks whether the estimated required energy will be supplied fully by the external charge energy. If the full supply is not possible, the control apparatus causes electric power generation by the motor/generator at some point in the planned travel route, where the efficiency of electric power generation is good, thereby to supplement insufficiency of energy.
