Abstract:
1. A hybrid vehicle control apparatus for a hybrid vehicle capable of EV travel generated by a motor-generator with an internal combustion engine in a stopped state, the control apparatus comprising: a battery connected to the motor-generator, wherein the battery provides electric power to the motor-generator and receives electric power from the motor-generator; an electrically-heated catalyst heatable by electric power from the battery for purifying an exhaust gas of the internal combustion engine; a maximum value calculation unit for calculating a maximum value of a supply of electric power for the electrically-heated catalyst, when the internal combustion engine is in the stopped state, that is provided to the electrically-heated catalyst as a function of (i) at least one of a start-up electric power required for starting up the engine or an operation electric power required for operating a supplemental device, (ii) an electric power output limit value of the battery, and (iii) an electric power required for a travel of the hybrid vehicle; and a power supply controller for controlling the supply of electric power for the electrically-heated catalyst based on the maximum value of the supply of electric power for the electrically-heated catalyst.
