<p>An occupant protection device includes (i) an electronic control unit having a control board, (ii) a parallel connection bus having two lines, (iii) multiple satellite sensors connected to the parallel connection bus, (iv) a squib connected to the parallel connection bus, and (v) an accident prevention diode located close to the squib. The control board includes an interface and a processor. Each of the satellite sensors includes a distributed system interface which is located between the two lines. The parallel connection bus is supplied with a sensor drive voltage. The electronic control unit starts to operate at least one of the occupant protection portions based on a result of the collision determination by the control board.</p> |
