  • Publication number: 20080249684
    Abstract: An overturn prevention control device for a two-wheel vehicle having a vehicle body, a front wheel, an actuator that steers the front wheel, a rear wheel, and a rear-wheel driving portion, includes an angular velocity sensor and a control unit arranged to output a steering angle command signal for controlling the actuator. The angular velocity sensor includes a detection axis, is mounted on the vehicle body such that the detection axis is downwardly inclined at a predetermined angle relative to a forward direction of the vehicle body, and detects an angular velocity about the detection axis. The angular velocity detected by the angular velocity sensor includes an angular velocity in a lateral direction of inclination and an angular velocity in an azimuthal direction. The zero-set error and offset noise are incorporated into the azimuth angle command. Thus, the two-wheel vehicle can be prevented from overturning.
