Abstract
An inverted two-wheel vehicle includes: an inverted two-wheel vehicle body; an acceleration sensor and a gyro sensor which are mounted on the same substrate; and an ECU. The ECU calculates a mounting angle error of the acceleration sensor with respect to the inverted two-wheel vehicle body based on an output value of the acceleration sensor obtained when the inverted two-wheel vehicle is brought into a stationary state in a state where a reference yaw axis of the inverted two-wheel vehicle is made coincident with a vertical direction, and corrects an output value of the gyro sensor by using the mounting angle error of the acceleration sensor with respect to the inverted two-wheel vehicle body as a mounting angle error of the gyro sensor with respect to the inverted two-wheel vehicle body.
