<p><P>PROBLEM TO BE SOLVED: To provide an occupant crash protection device for efficiently reducing power consumption by considering the seated state of an occupant in the seat of a vehicle. <P>SOLUTION: It is judged whether the occupant is seated at a front passenger seat, based on a detection signal from a seating detection switch 15 (step 100). When occupants are judged not to be seated at the front passenger seat at this time, it is not necessary to expand a side air bag 4 for the front passenger seat. Therefore, power supply to a B pillar satellite sensor 10 utilized for expansion control in the side air bag 4 for the front passenger seat is shut off (step S110). Further, in this case, a CPU 24 does not execute reception processing of transmission signals from the B pillar satellite sensor 10, side collision judgment processing, based on the signal, and further the expansion processing, or the like, of the side air bag 4. Therefore, the power consumption of the B pillar satellite sensor 10 and an air bag ECU 13 can be reduced effectively. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
