Abstract

An occupant protection control device that performs operation control of a plurality of occupant protection devices provided in a vehicle, the occupant protection control device including a determination section that determines whether or not said vehicle has had a collision, based on acceleration data acquired from a plurality of acceleration sensors installed in predetermined locations of said vehicle, wherein when a side impact collision of said vehicle occurs, a seat belt pretensioner among said plurality of occupant protection devices is inhibited to be operated, and when a frontal oblique impact collision of said vehicle occurs, said seat belt pretensioner is operated after a curtain airbag, among said plurality of occupant protection devices, is operated.

Claims

1. An occupant protection control device that performs operation control of a plurality of occupant protection devices provided in a vehicle, the occupant protection control device comprising a determination section that determines whether or not said vehicle has had a collision, based on acceleration data acquired from a plurality of acceleration sensors installed in predetermined locations of said vehicle, wherein

when a side impact collision of said vehicle occurs, a seat belt pretensioner among said plurality of occupant protection devices is inhibited to be operated, and

when a frontal oblique impact collision of said vehicle occurs, said seat belt pretensioner is operated after a curtain airbag, among said plurality of occupant protection devices, is operated.

2. The occupant protection control device according to claim 1, wherein

when a side impact collision of said vehicle occurs, a side impact occupant protection device including said curtain airbag, among said plurality of occupant protection devices, is operated,

when a frontal oblique impact collision of said vehicle occurs, it is determines by said determination section whether or not said curtain airbag has been operated, and

when it is determined that said curtain airbag has been operated, said seat belt pretensioner is operated.

3. The occupant protection control device according to claim 1, wherein

when a frontal impact collision of said vehicle occurs, a frontal impact occupant protection device including said seat belt pretensioner, among said plurality of occupant protection devices, is operated.

5. An occupant protection system comprising:

a plurality of acceleration sensors installed in predetermined locations of a vehicle;

a plurality of occupant protection devices provided in said vehicle; and

an occupant protection control device according to claim 1.

9. The occupant protection control device according to claim 2, wherein

when a frontal impact collision of said vehicle occurs, a frontal impact occupant protection device including said seat belt pretensioner, among said plurality of occupant protection devices, is operated.

4. An occupant protection control device that performs operation control of a plurality of occupant protection devices provided in a vehicle, the occupant protection control device comprising a determination section that determines whether or not said vehicle has had a collision, based on acceleration data acquired from a plurality of acceleration sensors installed in predetermined locations of said vehicle, wherein

when a frontal impact collision of said vehicle occurs, a frontal impact occupant protection device including a seat belt pretensioner, among said plurality of occupant protection devices, is operated, and

when a side impact collision of said vehicle occurs, said seat belt pretensioner is inhibited to be operated.

6. An occupant protection system comprising:

a plurality of acceleration sensors installed in predetermined locations of a vehicle;

a plurality of occupant protection devices provided in said vehicle; and

an occupant protection control device according to claim 4.

7. An occupant protection control method that performs operation control of a plurality of occupant protection devices provided in a vehicle, the method comprising the steps of:

determining whether or not said vehicle has had a collision, based on acceleration data acquired from a plurality of acceleration sensors installed in predetermined locations of said vehicle;

inhibiting operation of a seat belt pretensioner among said plurality of occupant protection devices, when a side impact collision of said vehicle occurs; and

operating said seat belt pretensioner after operating a curtain airbag among said plurality of occupant protection devices, when a frontal oblique impact collision of said vehicle occurs.

8. An occupant protection control method that performs operation control of a plurality of occupant protection devices provided in a vehicle, the method comprising the steps of:

determining whether or not said vehicle has had a collision, based on acceleration data acquired from a plurality of acceleration sensors installed in predetermined locations of said vehicle;

operating a frontal impact occupant protection device including a seat belt pretensioner, of said plurality of occupant protection devices, when a frontal impact collision of said vehicle occurs; and

inhibiting operation of said seat belt pretensioner, when a side impact collision of said vehicle occurs.
