Abstract
Automatic tilting vehicle is provided that includes left and right front wheels supported by knuckles, a rear wheel steered by a steering actuator, a vehicle tilting device, and a control unit. The control unit calculates a target tilt angle of the vehicle and a target steered angle of the rear wheel based on a steering angle and a vehicle speed, controls the vehicle tilting device so that a tilt angle of the vehicle becomes the target tilt angle, and controls the steering actuator so that a steered angle of the rear wheel becomes the target steered angle. When the vehicle is turning and decelerating, a steered angle of the rear wheel is controlled not to be the target steered angle but to zero, and a tilt angle of the vehicle is reduced by a gyro moment of the rear wheel.
