Provided is an automatic three-wheeled vehicle that can increase cornering performance without using a differential gear or an active suspension. The vehicle is provided with a control unit that drives an outer wheel using a drive means at a rotational speed ratio (R). When a vehicle body is caused to follow a curve by a rotating operation of a steering wheel, on the assumption that no slip is caused between each of left and right rear wheels and a road surface, if a travel speed (V) is equal to or greater than a predetermined speed (V1) and if a steering angle ([theta]) of the steering wheel detected by a steering angle detection means is equal to or greater than a predetermined angle ([theta]1), an additional rotational speed ratio (Rd1) in accordance with the travel speed (V) and the steering angle ([theta]) is added to a required outer wheel rotational speed ratio (R0); which is a rotational speed ratio obtained in accordance with the steering angle ([theta]) and required for the outer wheel relative to the inner wheel, so as to calculate the rotational speed ratio (R).
