Abstract
A vehicle includes an internal combustion engine. The internal combustion engine includes an exhaust passage, and a filter for collecting particulate matter contained in the exhaust gas. The vehicle includes a cooling fan for circulating air around a radiator and the filter. A control device of the vehicle executes an accumulated amount calculation process for calculating a particulate matter accumulated amount. The control device executes a regeneration process under a condition that the particulate matter accumulated amount exceeds a specified amount. The regeneration process is a process for regenerating the filter when the particulate matter collected on the filter is combusted. The control device executes a fan drive process for driving the cooling fan. When the regeneration process is being executed, the control device executes the fan drive process regardless of a coolant temperature under a condition that a vehicle speed is smaller than a specified speed.
