Abstract
To provide a method of determining the presence and the kind of the object on the seat of the passenger vehicle accurately. When the seat weight w is below w1, it is determined that the seat vacant. When the seat weight is equal to or above w1, determination is made whether or not the output p of the living body proximity sensor is below the threshold value p1. In the case where the output p of the living body proximity sensor is below the threshold value p1, it is determined that a child is sitting on the seat when the seat weight is below w2, and that an adult is sitting on the seat when the seat weight is equal to or above w2. When the output of the living body proximity sensor is equal to or above threshold value p1, it is determined that a child seat is mounted on the seat.
