A CPU prompts a user to drive a vehicle to a repair shop by operating a display when an amount of PM deposited in a GPF increases. When a regeneration request for the GPF is input from a shop-side terminal in the repair shop, the CPU performs a regeneration process in a state in which the vehicle stops. The CPU controls a temperature of the GPF such that the temperature at the time of execution of the regeneration process becomes lower when an opening/closing member is in a closed state than when the opening/closing member is in an open state.
