摘要: 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.

The feedback quantity of the torque coefficient setting unit when the steering torque is in a predetermined high-frequency range is larger than the feedback quantity of the steering angular velocity coefficient setting unit when the steering angular velocity is in a predetermined high-frequency range.

摘要: A boundary layer control system includes a boundary layer separating portion that separates a boundary layer of an airflow at an underside of a body of a moving object from a main flow of the airflow, and an ejecting portion that ejects fluid in a state different from that of the boundary layer and the main flow, between the boundary layer and the main flow that have been separated by the boundary layer separating portion. This boundary layer control system is characterized in that boundary layer and the main flow are reliably separated by the fluid in a state different from that of the boundary layer and the main flow, so the percentage of the main flow that is slowed down (i.e., reduced in velocity) by the boundary layer is reduced.
