Abstract

A first determination unit provisionally determines collision or non-collision between a vehicle and another vehicle on the basis of positional information of the vehicle and positional information of the other vehicle. A second determination unit changes a determination result to collision when the provisional determination result has been collision N times in succession and when the determination result was previously non-collision, and changes the determination result to non-collision when the provisional determination result has been non-collision M times in succession and when the determination result was previously collision. Here, N is smaller than M. N and M are positive integral numbers.

Claims

1. A radio apparatus that can be mounted in a vehicle, comprising:

an acquirer that acquires first positional information of a vehicle in which the radio apparatus is mounted;

a receiver that receives, from another radio apparatus, a packet signal that includes at least second positional information of another vehicle in which the other radio apparatus is mounted;

a first determiner that provisionally determines collision or non-collision between the vehicle and the other vehicle on the basis of the first positional information that is acquired by the acquirer and the second positional information included in the packet signal that is received by the receiver; and

a second determiner that collects a plurality of provisional determination results from the first determiner and determines collision or non-collision between the vehicle and the other vehicle based on the collected plurality of the provisional determination results.

2. The radio apparatus according to claim 1,

wherein the second determiner changes a determination result to collision when the provisional determination result has been collision N times in succession and when the determination result was previously non-collision.

3. The radio apparatus according to claim 1,

wherein the second determiner changes a determination result to collision when a rate of collision in a plurality of provisional determination results exceeds a first threshold value and when the determination result was previously non-collision.

11. The radio apparatus according to claim 2,

wherein the second determiner changes the determination result to non-collision when the provisional determination result has been non-collision M times in succession and when the determination result was previously collision, and

wherein N is smaller than M in the second determiner.

12. The radio apparatus according to claim 11,

wherein N and M are positive integral numbers.

13. The radio apparatus according to claim 3,

wherein the second determiner changes a determination result to non-collision when a rate of non-collision in a plurality of provisional determination results exceeds a second threshold value and when the determination result was previously collision, and

wherein the first threshold value is smaller than the second threshold value in the second determiner.

4. A process apparatus, comprising:

an acquirer that acquires a provisional determination result regarding collision or non-collision between a first vehicle and a second vehicle, that is determined on the basis of i) first positional information of the first vehicle in which a first radio apparatus that is mounted in a first vehicle is mounted and ii) second positional information of the second vehicle that is included in a packet signal that is received from a second radio apparatus by the first radio apparatus and that at least includes the second positional information of the second vehicle in which the second radio apparatus is mounted, and

a determiner that collects a plurality of provisional determination results that is acquired by the acquirer and determines collision or non-collision between the first vehicle and the second vehicle based on the collected plurality of the provisional determination results.

5. The process apparatus according to claim 4,

wherein the acquirer includes an inputter that inputs the first positional information and the second positional information, and

a provisional determiner that provisionally determines collision or non-collision between the first vehicle and the second vehicle on the basis of the first positional information and the second positional information.

6. The process apparatus according to claim 4,

wherein the determiner changes a determination result to collision when the provisional determination result has been collision N times in succession and when the determination result was previously non-collision.
