DRIVE CONTROL METHOD OF OCCUPANT PROTECTION CONTROL APPARATUS AND OCCUPANT PROTECTION CONTROL APPARATUS
First Claim
1. A drive control method of an occupant protection control apparatus for controlling the operation of a two-stage ignition-type occupant protection apparatus having two ignition means,wherein, when a first ignition means of the occupant protection apparatus is in failed state at the time when the first ignition means is normally scheduled to be ignited, a second ignition means in place of the first ignition means is ignited at the time when the first ignition means is normally scheduled to be ignited, and the first ignition means is ignited at the time when the second ignition means is normally scheduled to be ignited.

Abstract
An occupant protection apparatus can reduce the impact on an occupant as much as possible to securely protect the occupant even when a first-stage ignition means is in failed state.
In igniting a first squib 3a for driver seat, if determined that the first squib 3a for driver seat has been diagnosed to be in failed state (S204), a second squib 3b for driver seat in place of the first squib 3a for driver seat is ignited at the time when the first squib 3a for driver seat is normally scheduled to be ignited (S400), then the first squib 3a for driver seat is ignited at the time when the second squib 3b for driver seat is normally scheduled to be ignited (S600), which enables explosion of a driver airbag apparatus 3 without a delay as much as possible to improve the assurance and reliability of occupant protection.

3. An occupant protection control apparatus for drive-controlling a two-stage ignition-type occupant protection apparatus having two ignition means, comprising:
- a control unit capable of ignition control of the two ignition means based on the determination result of whether or not a vehicle crash has occurred; and
an interface circuit capable of igniting the two ignition means based on the determination of means performed by the control unit,wherein, when a failure diagnosis of the first ignition means is performed and it is diagnosed that the first ignition means is in failed state, the control unit, in order to ignite the ignition means, ignites the second ignition means in place of the first ignition means at the time when the first ignition means is normally scheduled to be ignited, and ignites the first ignition means at the time when the second ignition means is normally scheduled to be ignited. - View Dependent Claims (4)
