ELECTRIC HEATING CATALYST APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an electric heating catalyst apparatus that reduces power consumption by controlling an unnecessary operation.

SOLUTION: An EHC100 is provided in a hybrid vehicle that is driven by combining a motor 20 and an engine 10. The EHC100 includes: a battery 40 for supplying power to the motor 20; a catalyst 60 provided in an exhaust passage 15 of the engine 10; a heater 70 for heating the catalyst 60 by the energization of power of the battery 40; an ECU 50 for controlling the energization of the heater 70; a navigation system 80 having future vehicle information on the vehicle in the future that is from the current time to a prescribed later time; and a catalyst temperature sensor 51 for detecting a temperature of the catalyst 60. The ECU 50 controls the energization of the heater 70 based on the catalyst temperature detected by the sensor 51 and the future vehicle information in the navigation system 80.
