To provide a self-standing automatic vehicle capable of traveling in a self-standing state while controlling attitude of a vehicle body in response to a demand of a driver who is static with respect to the vehicle body.

When the motorcycle 1 turns left or right, a body inclination sensor sequentially detects a body inclined amount that should correspond to acceleration at that moment, rotational torque corresponding to a detection result is generated by an actuator, the body 2 is inclined a predetermined amount by gyroscopic moment generated by a body position control means 6, an inclined direction of the body 2 is constantly matched with a direction of resultant force acting on a center of gravity of the body, a left turn can be made while maintaining a balance between moment based upon centrifugal force at that moment, moment based upon gravity, and the gyroscopic moment from the body position control means 6, and the driver has to just be static on the body 2 without moving body weight.
