CATALYST ENERGIZATION CONTROLLER FOR HYBRID AUTOMOBILE

摘要

PPROBLEM TO BE SOLVED: To effectively use regenerative electric power, in a catalyst energization controller for controlling energization of a catalyst, in a hybrid automobile provided with the catalyst with an electric heater such as an EHC, for example. PSOLUTION: This catalyst energization controller controls the energization to the electrically-heated catalyst, in the hybrid automobile 100 provided with an internal combustion engine 10, a motor-driven electric generator 13, a battery 15, and the electrically-heated catalyst 21 arranged in an exhaust passage of the internal combustion engine and heated by the energization. The catalyst energization controller is provided with a charge amount specifying means for specifying a charge amount of the battery, and a regenerative electric power supply means for supplying the regenerative electric power generated by the motor-driven electric generator, to be selectively charged to the battery or the energization, according to the specified charge amount.
