Vehicle group control method and vehicle
First Claim
1. A vehicle group control method that controls the traveling of a vehicle group including a plurality of vehicles which travel in a row, each of the vehicles including an electronic control unit (ECU), comprising:
- a step of controlling vehicles in each of a plurality of small vehicle groups which are divided from the vehicle group and controlling a relative relationship between the vehicles in each small vehicle group using communication between the ECUs of the vehicles in the corresponding small vehicle group; and
a small vehicle group control step of controlling a relative relationship between the small vehicle groups using communication between the ECUs of representative vehicles in the small vehicle groups,wherein, in the small vehicle group control step, when a host vehicle is the representative vehicle in each of the small vehicle groups other than a first small vehicle group, the traveling of the representative vehicles in the small vehicle groups other than a first small vehicle group is controlled using communication between the host vehicle and the representative vehicle in the small vehicle group that is just in front of the small vehicle group including the host vehicle such that a distance from the representative vehicle in the small vehicle group which is just in front of the small vehicle group including a host vehicle is maintained to be uniform.

Abstract
The invention provides a vehicle group control method that controls the traveling of a vehicle group including a plurality of vehicles. The vehicle group control method includes: a process of controlling vehicles in each of a plurality of small vehicle groups which are divided from the vehicle group and controlling the relative relationship between the vehicles in each small vehicle group using communication between the vehicles in the same small vehicle group; and a small vehicle group control process of controlling the relative relationship between the small vehicle groups using communication between representative vehicles in the small vehicle groups.

1. A vehicle group control method that controls the traveling of a vehicle group including a plurality of vehicles which travel in a row, each of the vehicles including an electronic control unit (ECU), comprising:
-
a step of controlling vehicles in each of a plurality of small vehicle groups which are divided from the vehicle group and controlling a relative relationship between the vehicles in each small vehicle group using communication between the ECUs of the vehicles in the corresponding small vehicle group; and a small vehicle group control step of controlling a relative relationship between the small vehicle groups using communication between the ECUs of representative vehicles in the small vehicle groups, wherein, in the small vehicle group control step, when a host vehicle is the representative vehicle in each of the small vehicle groups other than a first small vehicle group, the traveling of the representative vehicles in the small vehicle groups other than a first small vehicle group is controlled using communication between the host vehicle and the representative vehicle in the small vehicle group that is just in front of the small vehicle group including the host vehicle such that a distance from the representative vehicle in the small vehicle group which is just in front of the small vehicle group including a host vehicle is maintained to be uniform. - View Dependent Claims (5)

2. A vehicle group control method that controls the traveling of a vehicle group including a plurality of vehicles which travel in a row, each of the vehicles including an electronic control unit (ECU), comprising:
-
a step of controlling vehicles in each of a plurality of small vehicle groups which are divided from the vehicle group and controlling a relative relationship between the vehicles in each small vehicle group using communication between the ECUs of the vehicles in the corresponding small vehicle group; and a small vehicle group control step of controlling a relative relationship between the small vehicle groups using communication between the ECUs of representative vehicles in the small vehicle groups, wherein, in the small vehicle group control step, the traveling of each of the representative vehicles other than the representative vehicle in the small vehicle group including a target vehicle which is selected from the vehicles in the vehicle group is controlled such that a distance between the target vehicle and each of the representative vehicles other than the representative vehicle in the small vehicle group including the target vehicle is maintained to be uniform, using communication between the representative vehicle in the small vehicle group including the target vehicle and each of the representative vehicles other than the representative vehicle in the small vehicle group including the target vehicle.

3. A vehicle group control method that controls the traveling of a vehicle group including a plurality of vehicles, each of the vehicles including an electronic control unit (ECU), comprising:
-
a step of controlling vehicles in each of a plurality of small vehicle groups which are divided from the vehicle group and controlling a relative relationship between the vehicles in each small vehicle group using communication between the ECUs of the vehicles in the corresponding small vehicle group; and a small vehicle group control step of controlling a relative relationship between the small vehicle groups using communication between the ECUs of representative vehicles in the small vehicle groups, wherein, in the small vehicle group control step, a relative relationship between a target vehicle selected from the vehicles in the vehicle group and each of the representative vehicles other than the representative vehicle in the small vehicle group including the target vehicle is controlled using communication between the representative vehicle in the small vehicle group including the target vehicle and each of the representative vehicles other than the representative vehicle in the small vehicle group including the target vehicle, in the small vehicle group including the target vehicle, the target vehicle is a first vehicle in the small vehicle group, and the representative vehicle is selected from vehicles other than the first vehicle.

4. A vehicle group control method that controls the traveling of a vehicle group including a plurality of vehicles, each of the vehicles including an electronic control unit (ECU), comprising:
-
a step of controlling vehicles in each of a plurality of small vehicle groups which are divided from the vehicle group and controlling a relative relationship between the vehicles in each small vehicle group using communication between the ECUs of the vehicles in the corresponding small vehicle group; and a small vehicle group control step of controlling a relative relationship between the small vehicle groups using communication between the ECUs of representative vehicles in the small vehicle groups, wherein, in the step of controlling the vehicles in the small vehicle group, a distance between the vehicles in the small vehicle group is controlled, and the number of vehicles in each small vehicle group is determined by an error in a distance between the vehicles behind a first vehicle that can occur in correspondence with the acceleration of the first vehicle in the small vehicle group in the step of controlling the vehicles in the small vehicle group.

6. A vehicle group control method that controls the traveling of a vehicle group including a plurality of vehicles, each of the vehicles including an electronic control unit (ECU), comprising:
-
a step of controlling vehicles in each of a plurality of small vehicle groups which are divided from the vehicle group and controlling a relative relationship between the vehicles in each small vehicle group using communication between the ECUs of the vehicles in the corresponding small vehicle group; and a small vehicle group control step of controlling a relative relationship between the small vehicle groups using communication between the ECUs of representative vehicles in the small vehicle groups, wherein, in the small vehicle group control step, the relative relationship between the representative vehicles is controlled such that a distance between the successive small vehicle groups is a predetermined target distance, and the predetermined target distance is set on the basis of an inter-vehicle error propagation ratio, which is the propagation ratio of the error in an inter-vehicle distance propagated to the vehicles that are behind each vehicle, in the step of controlling the vehicles in the small vehicle group.
