To provide a technique for detecting that an occupant boards or starts to board and that an article other than the occupant is mounted, while differentiating between the actions.
A sensor unit 3 includes an infrared sensor 4 for human body detection capable of detecting infrared rays emitted by the occupant who boards a body 2 or starts to board it. Preferably, the infrared sensor 4 is disposed at a boarding position (step 6) of the body 2. Preferably, the sensor unit 3 further includes a beam sensor 12 for emitting visible light or infrared rays toward the occupant who boards the body 2 or starts to board it and detecting the presence of the occupant with the reflected light. Preferably, the beam sensor 12 is disposed at the boarding position (step 6) of the body 2.
