Abstract
There are provided a particulate filter and a manual regeneration switch. When the manual regeneration switch is operated and the vehicle is in a stop state, the engine speed is adjusted to a first target higher than a normal idle speed to regenerate the filter. Meanwhile, when the vehicle changes from its stop state to its driving state, the engine speed is adjusted to a second target higher than the normal idle speed but lower than the first target in the event that the temperature of the filter is high, while the engine speed is adjusted to the normal idle speed in the event that the temperature of the filter is low. Accordingly, deterioration of the durability of the filter due to its rapid temperature increasing can be suppressed, avoiding disadvantages of fuel efficiency and vehicle start feeling.
