TILTING VEHICLE

WIPO Patent Application WO/2023/120572

A1

A tilting vehicle (1) includes wheels including a front steering wheel (11) and a rear wheel (12), a tilting actuator (120) that changes a tilting angle of a vehicle body, a steering actuator (110) that changes a steering angle of the front steering wheel (11), and a control device (100) that controls the tilting actuator (120) and the steering actuator (110). In a case of defining, with respect to the tilting angle of the vehicle body as to a perpendicular axis that is perpendicular to the ground, a turning state in which a resultant force of gravity and centrifugal force in the outward direction of turning is an angle as to the perpendicular axis as a balanced turning state, and a turning state in which a greater lateral acceleration occurs than the lateral acceleration in the balanced turning state as an imbalanced turning state, the control device (100) controls the tilting actuator (120) and the steering actuator (110) such that, when defining a speed region up to the highest speed as being equally divided into five parts, a rate of change of great lateral acceleration in the imbalanced turning state as to change in vehicle speed in a highest speed region is smaller than the rate of change of great lateral acceleration in the imbalanced turning state as to change in vehicle speed in a lowest speed region.
