Abstract: A sensor unit including an object detection sensor and an inclination sensor is mounted to a vehicle, and axial misalignment of the object detection sensor is determined as follows. A first inclination angle acquiring step of disposing the sensor unit, so that a first predetermined direction is aligned with a second predetermined direction before the sensor unit is mounted to the vehicle, and acquiring a first inclination angle detected by the inclination sensor from the inclination sensor, is performed. Then, a second inclination angle acquiring step of mounting the sensor unit on the vehicle and acquiring a second inclination angle detected by the inclination sensor from the inclination sensor, is performed. Finally, an axial misalignment determining step of determining whether axial misalignment has occurred at the object detection sensor, based on the first inclination angle and the second inclination angle, is performed.
