发明名称 Vehicle control device
摘要 A vehicle control device applied to a vehicle including an internal combustion engine and an electrically heated catalyst which is warmed by applying a current, and includes a catalyst carrier supporting a catalyst and a carrier retention unit that retains the catalyst carrier and has an electrical insulation property. The control unit performs a control of suppressing a supply of an unburned gas from the internal combustion engine to the electrically heated catalyst so that the carrier retention unit is maintained at a lower temperature than the catalyst, when a condition for performing a fuel cut of the internal combustion engine during a deceleration is satisfied. Therefore, it is possible to suppress a rapid cooling of the catalyst, and it becomes possible to maintain a temperature of the carrier retention unit at a lower temperature than a temperature of the catalyst.
