First Claim
1. A vehicle including two drive wheels arranged in opposition to each other on an axle, comprising:
- a riding portion for accommodating a weight body;
center-of-gravity position acquisition means for acquiring a center-of-gravity position;
lateral acceleration acquisition means for acquiring a lateral acceleration which is an acceleration component parallel to the axle;
movement amount determination means for determining an amount of movement of the center-of-gravity position in a left-right direction in accordance with the acquired center-of-gravity position and magnitude of the acquired lateral acceleration; and
center-of-gravity movement means for causing the center-of-gravity position to move in accordance with the determined amount of movement of the center-of-gravity position.

Abstract
A transverse two-wheeled vehicle has an increased turning limit value. A turning limit estimation system obtains a turning limit value and a center-of-gravity position adjustment system improves the obtained turning limit value. The turning limit estimation system obtains values for turning limit and turning stability by estimating a center-of-gravity position and a lateral acceleration. In the center-of-gravity position adjustment system, the turning limit value is increased by causing the estimated center-of-gravity position to move toward a centripetal direction. The mechanism for moving the center of gravity to is one or more of i) a vehicle body tilt mechanism, ii) a weight movement mechanism, and iii) a seat parallel movement mechanism. Accordingly, particularly a vehicle with two wheels narrowly spaced and a high center of gravity, can make a faster and smaller turn, and driving performance, stability, and security of the turning operation are improved.
