Patent number: 11198483Abstract: Flexibility in design of steering characteristics is enhanced in a leaning vehicle including two front steerable wheels. A vehicle includes a body frame, a left front wheel, a right front wheel, a rear wheel, a leaning mechanism, a steering mechanism, and a leaning-responsiveness-adjusting mechanism. The leaning mechanism includes arms rotatably supported by the body frame. The arms rotate with respect to the body frame so that the body frame leans. The steering mechanism mechanically transfers rotation of the handle to the left front wheel and the right front wheel. Accordingly, the body frame leans in the direction opposite to the rotation direction of the handle. The leaning-responsiveness-adjusting mechanism controls a motor by using an instruction value based on a time derivative value of a physical quantity generated by a motion of a rider affecting leaning of the body frame to thereby adjust responsiveness of leaning of the body frame.Type: GrantFiled: September 13, 2019Date of Patent: December 14, 2021Assignee: YAMAHA HATSUDOKI KABUSHIKI KAISHAInventors: Nobuo Hara, Yukihide Fukuhara, Tatsuya Nagata
