Abstract: A braking/driving force control system, during control for maintaining a target vehicle speed, performs fuel cut and then, when a required braking/driving force for maintaining the target vehicle speed reduces, makes a downshift while fuel cut is continued. The braking/driving force control system causes a brake to generate a braking force such that the sum of a braking/driving force that a powertrain generates and the braking force that the brake generates agrees with the required braking/driving force. Thus, good fuel efficiency and riding comfort are obtained.
