Abstract

In a vehicle emergency call apparatus, a call determining unit determines whether or not a degree of damage to at least one occupant seated in at least one vehicle seat is a predetermined degree required for an emergency call to be made, based on a detected impact magnitude applied to a vehicle and a predetermined impact magnitude. The call determining unit sets the predetermined impact magnitude to a first impact magnitude when a belt-wearing detector detects that at least one occupant seated in the at least one vehicle seat does not wear the seatbelt, and sets the predetermined impact magnitude to a second impact magnitude when the belt-wearing detector detects that the at least one occupant seated in the at least one vehicle seat wears the seatbelt. The first impact magnitude is set to be smaller than the second impact magnitude.

Claims

1. A vehicle emergency call apparatus comprising:

an impact amount detector that detects an impact magnitude applied to a vehicle from outside of the vehicle;

a seating detector that detects whether or not at least one occupant is seated in at least one vehicle seat in the vehicle;

a call determining unit that determines whether or not a degree of damage to the occupant seated in the vehicle seat is a predetermined degree required for an emergency call to be made, based on the detected impact magnitude applied to the vehicle and a predetermined impact magnitude; and

a calling unit that makes an emergency call to a rescue center, if it is determined that the degree of damage to the at least one occupant is the predetermined degree required for the emergency call to be made or more, based on determination results of the call determining unit;

a belt-wearing detector that detects whether or not the at least one occupant seated in the at least one vehicle seat wears a seatbelt,

the call determining unit setting the predetermined impact magnitude to a first impact magnitude when the belt-wearing detector detects that the at least one occupant seated in the at least one vehicle seat does not wear the seatbelt, and setting the predetermined impact magnitude to a second impact magnitude when the belt-wearing detector detects that the at least one occupant seated in the at least one vehicle seat wears the seatbelt, the first impact magnitude being set to be smaller than the second impact magnitude.

2. The vehicle emergency call apparatus according to claim 1, wherein:

when the belt-wearing detector detects that the at least one occupant seated in the at least one vehicle seat does not wear the seatbelt, the call determining unit determines that the degree of damage is the predetermined degree required for an emergency call to be made, if the detected impact magnitude applied to the vehicle is equal to or larger than a first threshold that is set as the first impact magnitude;

when the belt-wearing detector detects that the at least one occupant seated in the at least one vehicle seat wears the seatbelt, the call determining unit determines that the degree of damage is the predetermined degree required for an emergency call to be made, if the detected impact magnitude applied to the vehicle is equal to or larger than a second predetermined threshold that is larger than the first threshold and is set as the second impact magnitude; and

the call determining unit increases or decreases the first predetermined threshold and the second predetermined threshold, based on a combination of a collision position of the vehicle and a seating position of the occupant seated in the vehicle seat.

3. The vehicle emergency call apparatus according to claim 1, wherein:

when the emergency call is made, the calling unit gives notification of the number of occupants to which the degree of damage is determined to be the predetermined degree required for the emergency call to be made.

4. The vehicle emergency call apparatus according to claim 2, wherein:

when the emergency call is made, the calling unit gives notification of the number of occupants to which the degree of damage is determined to be the predetermined degree required for the emergency call to be made.

5. The vehicle emergency call apparatus according to claim 1, wherein:

the belt-wearing detector comprises a buckle switch for the seatbelt.

6. The vehicle emergency call apparatus according to claim 2, wherein:

the belt-wearing detector comprises a buckle switch for the seatbelt.

7. The vehicle emergency call apparatus according to claim 3, wherein:

the belt-wearing detector comprises a buckle switch for the seatbelt.

8. The vehicle emergency call apparatus according to claim 4, wherein:

the belt-wearing detector comprises a buckle switch for the seatbelt.

9. A vehicle emergency call method comprising:

detecting, by an impact amount detector, an impact magnitude applied to a vehicle (8) from outside of the vehicle;

detecting, by a seating detector, whether or not at least one occupant is seated in at least one vehicle seat in the vehicle;

detecting, by a call determining unit, whether or not a degree of damage to the occupant seated in the vehicle seat is a predetermined degree required for an emergency call to be made, based on the detected impact magnitude applied to the vehicle and a predetermined impact magnitude;

making, by a calling unit, an emergency call to a rescue center, if it is determined that the degree of damage to the at least one occupant is the predetermined degree required for the emergency call to be made or more, based on determination results of the call determining unit;

detecting, by a belt-wearing detector, whether or not the at least one occupant seated in the at least one vehicle seat wears a seatbelt;

when the belt-wearing detector detects that the at least one occupant seated in the at least one vehicle seat does not wear the seatbelt, setting, by the call determining unit, the predetermined impact magnitude to a first impact magnitude; and

when the belt-wearing detector detects that the at least one occupant seated in the at least one vehicle seat wears the seatbelt, setting, by the call determining unit, the predetermined impact magnitude to a second impact magnitude, the first impact magnitude being set to be smaller than the second impact magnitude.
