Abstract

A convoy travel control apparatus includes: a communication portion; a travel control portion; and a joining control portion, wherein when an own vehicle is travelling in convoy while being incorporated in a group of convoy vehicles travelling in convoy, if the communication portion has received, from an independent vehicle not incorporated in the group of convoy vehicles travelling in convoy, request information to incorporate the independent vehicle into the group of convoy vehicles, then the joining control portion determines a positional relationship between a position of the group of convoy vehicles and a position of the independent vehicle, and wherein if the independent vehicle is travelling along a side of the group of convoy vehicles, then in order to incorporate the independent vehicle into the group of convoy vehicles, the joining control portion exercises control on the group of convoy vehicles via the communication portion.

Claims

1. A convoy travel control apparatus, comprising:

a communication portion that communicates with another vehicle;

a travel control portion that actualizes travel in convoy with the another vehicle through communication via the communication portion;

a joining control portion;

a state information sharing portion that receives information indicative of a state in front of or behind group of convoy vehicles;

a communication control portion that receives, via the communication portion, at least either of image information in which an interior of a convoy vehicle incorporated in the group of convoy vehicles is imaged and voice information collected from the interior, and

a presentation portion that according to the information indicative of a state in front of or behind the group of convoy vehicles, determines whether each of the group of convoy vehicles is capable of travelling safely or not and presents at least either of the image information and the voice information,

wherein when an own vehicle is travelling in convoy while being incorporated in the group of convoy vehicles travelling in convoy, if the communication portion has received, from an independent vehicle not incorporated in the group of convoy vehicles travelling in convoy, request information to incorporate the independent vehicle into the group of convoy vehicles, then the joining control portion exercises control, which is for incorporating the independent vehicle into the group of convoy vehicles, on the group of convoy vehicles via the communication portion.

2. The convoy travel control apparatus according to claim 1,

wherein the presentation portion presents a fact that the communication portion has received a request to incorporate the independent vehicle into the group of convoy vehicles.

3. The convoy travel control apparatus according to claim 1, further comprising

an operation input portion that accepts an operation input for selecting whether to approve a request to incorporate the independent vehicle into the group of convoy vehicles or not, wherein

the joining control portion transmits information, which indicates the operation input, to the independent vehicle via the communication portion.

4. The convoy travel control apparatus according to claim 2, wherein

the presentation portion presents information indicative of the position of the independent vehicle.

5. The convoy travel control apparatus according to claim 1, wherein:

when the own vehicle is travelling in convoy while being incorporated in the group of convoy vehicles, the joining control portion determines whether convoy vehicles have come to be at a predetermined inter-vehicular distance or not, and

the joining control portion transmits information, which indicates whether the convoy vehicles have come to be at the predetermined inter-vehicular distance or not, to the independent vehicle via the communication portion.

6. The convoy travel control apparatus according to claim 5, wherein

if before incorporation into the group of convoy vehicles, the own vehicle is the independent vehicle, and the convoy vehicles have come to be at the predetermined inter-vehicular distance, then the joining control portion causes the own vehicle to be incorporated into the group of convoy vehicles.

7. The convoy travel control apparatus according to claim 1, further comprising:

a sensor portion that measures an inter-vehicular distance between the own vehicle and a preceding vehicle; and

an inter-vehicular distance control portion that controls travel drive of the own vehicle so that the inter-vehicular distance measured by the sensor portion is a set distance, wherein;

the joining control portion determines whether the preceding vehicle is the independent vehicle or not,

if the preceding vehicle is the independent vehicle, then based on the inter-vehicular distance measured by the sensor portion, the inter-vehicular distance control portion controls the inter-vehicular distance from the own vehicle to the preceding vehicle, and

if the preceding vehicle is not the independent vehicle, then based on information indicative of a position of the independent vehicle that has been received by the communication portion, the inter-vehicular distance control portion controls the inter-vehicular distance from the own vehicle to the preceding vehicle.

8. The convoy travel control apparatus according to claim 7, wherein

the travel control portion orders the inter-vehicular distance control portion to make an inter-vehicular distance between the independent vehicle and the own vehicle equal to a preset distance.

10. The convoy travel control apparatus according to claim 1, wherein

based on an operation input, the communication control portion transmits voice information collected from an own vehicle.

11. The convoy travel control apparatus according to any claim 1, further comprising

a storage portion that stores point information granted to a driver according to experience of driving the convoy vehicle, wherein

the presentation portion presents the point information.

12. The convoy travel control apparatus according to claim 11, wherein

the storage portion stores point information granted to the driver according to the experience that satisfies a preset condition.

13. The convoy travel control apparatus according to claim 1, further comprising

a position information sharing portion that receives, via the communication portion, information indicative of a trail of a preceding vehicle, wherein

the travel control portion causes an own vehicle to follow the trail.

14. The convoy travel control apparatus according to claim 1, wherein:

the joining control portion determines a positional relationship between a position of the group of convoy vehicles and a position of the independent vehicle, and

if the independent vehicle is travelling along a side of the group of convoy vehicles, then in order to incorporate the independent vehicle into the group of convoy vehicles, the joining control portion makes longer an inter-vehicular distance between the convoy vehicles incorporated in the group of convoy vehicles.

15. The convoy travel control apparatus according to claim 1, wherein

if no other vehicle is present around the group of convoy vehicles, then the communication control portion determines whether each of the group of convoy vehicles is capable of travelling safely or not.

16. The convoy travel control apparatus according to claim 1, wherein

if a road shape ahead of the group of convoy vehicles is a straight line, then the communication control portion determines whether each of the group of convoy vehicles is capable of travelling safely or not.

17. The convoy travel control apparatus according to claim 1, wherein

if timing indicated by received lighting timing information matches with timing at which a light source portion imaged by a forward imaging portion lights up, then the travel control portion determines that an imaged preceding vehicle is a communication vehicle.

18. The convoy travel control apparatus according to claim 1, wherein

if any of the convoy vehicles ahead judges that an obstacle is not present ahead, then the travel control portion judges that the obstacle is not present either for the own vehicle.

19. The convoy travel control apparatus according to claim 1, wherein

a driver of the independent vehicle is capable of selecting from which of front, behind, and side of the convoy vehicle incorporated in the group of convoy vehicles, the independent vehicle is to merge with the group of convoy vehicles.
