Abstract

When determining a collision possibility of a vehicle while an emergency report is not being executed, an in-vehicle emergency report apparatus secures a wireless communications resource by one of the following: (i) Rejecting a connection request for connecting a wireless communications link from a navigation system to a wireless communications device in respect of another use other than an emergency report; (ii) Disconnecting the wireless communications link connected by the wireless communications device according to a connection request from the navigation system in respect of another use other than an emergency report; (iii) Notifying the navigation system of prohibition of connecting the wireless communications link by the wireless communications device in another use other than an emergency report; and (iv) Restricting a connection band of the wireless communications link in the wireless communications device in respect of another use other than an emergency report from the navigation system.

Claims

1. An emergency report apparatus in a vehicle, the apparatus comprising:

a wireless communications device to transmit an emergency report signal; and

a control circuit to execute an emergency report by causing the wireless communications device to transmit an emergency report to transmit an emergency report signal when determining that a start trigger occurred,

the control circuit being further configured to,

when determining that there is a possibility that the vehicle collides and also an emergency report is not being executed,

secure a wireless communications resource for an emergency report to enable an emergency report.

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

when determining that there is a possibility that the vehicle collides and also an emergency report is not being executed, the control circuit determines whether the wireless communications device is in a dormant state; and

when it is determined that the wireless communications device is in the dormant state, the control circuit causes the wireless communications device to re-connect the, wireless communications link to be returned from the dormant state, securing a wireless communications resource for an emergency report.

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

the control circuit determines whether a start trigger of an emergency report occurs after securing the wireless communications resource for an emergency report; and

the control circuit causes the wireless communications device to transmit an emergency report signal when it is determined that the start trigger of the emergency report occurred.

4. The emergency report apparatus according to claim 1, wherein:

the control circuit secures the wireless communications resource for an emergency report after determining that the start trigger of the emergency report occurred; and

the control circuit causes the wireless communications device to transmit the emergency report signal.

5. The emergency report apparatus according to claim 1, wherein

the control circuit executes selectively one of two first and second operations,

the first operation determining whether a start trigger of an emergency report occurs after securing the wireless communications resource for an emergency report,

the second operation securing the wireless communications resource for an emergency report after determining that the start trigger of the emergency report occurred.

6. The emergency report apparatus according to claim 1, wherein

the control circuit secures a wireless communications resource for an emergency report to enable an emergency report by rejecting a connection request of the wireless communications link to the wireless communications device in another use other than an emergency report.

7. The emergency report apparatus according to claim 1, wherein

the control circuit secures a wireless communications resource for an emergency report to enable an emergency report by disconnecting any wireless communications link connected for another use other than an emergency report.

8. The emergency report apparatus according to claim 1, wherein

the control circuit secures a wireless communications resource for an emergency report to enable an emergency report by notifying prohibition of connecting the wireless communications link in the wireless communications device in another use other than an emergency report.

9. The emergency report apparatus according to claim 1, wherein

the control circuit secures a wireless communications resource for an emergency report to enable an emergency report by restricting a connection band of the wireless communications link in the wireless communications device in another use other than an emergency report.

10. The emergency report apparatus according to claim 2, wherein:

the control circuit determines whether a start trigger of an emergency report occurs after securing the wireless communications resource for an emergency report; and

the control circuit causes the wireless communications device to transmit an emergency report signal when it is determined that the start trigger of the emergency report occurred.

11. The emergency report apparatus according to claim 2, wherein:

the control circuit secures the wireless communications resource for an emergency report after determining that the start trigger of the emergency report occurred; and

the control circuit causes the wireless communications device to transmit the emergency report signal.

12. The emergency report apparatus according to claim 2, wherein

the control circuit executes selectively one of two first and second operations,

the first operation determining whether a start trigger of an emergency report occurs after securing the wireless communications resource for an emergency report,

the second operation securing the wireless communications resource for an emergency report after determining that the start trigger of the emergency report occurred.
