Abstract
An occupant detection apparatus for a vehicle is disclosed. The occupant detection apparatus includes a buckle switch, a seat position sensor and an electronic control unit. The electronic control unit includes a first active element and a second active element that respectively control energization of the buckle switch and the seat position sensor. The electric control unit performs on-off control on the first active element in such manner that: the first active element is held on for a predetermined period; and at a time of an end of the predetermined period, the first active element is switched off and the second active element is switched on. The occupant detection apparatus can reduce radio noise generated due to the energization of the buckle switch and the seat position sensor, and can minimize an influence of the radio noise on another electronic apparatus mounted in the vehicle.
