Abstract

Even if an adjustable speed limitation function (ASL) sets a vehicle speed upper limit to a relatively low vehicle speed, a control unitis configured to, in order to suppress the problem of a decrease in fuel efficiency while the ASL is executing the vehicle speed limitation, suppress an output of an engineso that the vehicle speed does not exceed the vehicle speed upper limit, and cause a gear stage of an automatic transmissionto be shifted up to a higher speed side gear stage having higher fuel efficiency than a gear stage that is set based on the driving state of a vehicle, when a deviation between the vehicle speed detected by a vehicle speed sensorand the vehicle speed upper limit that is set by a vehicle speed upper limit setting switchbecomes less than a predetermined threshold.
