Abstract

Provided is a vehicle control system for avoiding a collection between a right-turning vehicle and a straight-through vehicle without decreasing comfort for an occupant. In the system, a first vehicle V 1 and a second vehicle V 2 retain high-precision map data for identifying a traveling lane. When the first vehicle V 1 traveling in an autonomous driving mode intends to turn right from a right turn lane at an intersection ahead based on the high-precision map data, the first vehicle V 1 transmits a right turn notification indicating the intention to turn right to nearby vehicles using vehicle-to-vehicle communications. When the second vehicle V 2 traveling in an autonomous driving mode intends to travel straight at an intersection ahead, the second vehicle V 2 recognizes a right-turning vehicle in an oncoming lane at the intersection upon receiving the right turn notification from the right-turning vehicle, and performs a predetermined control for collision avoidance.

First claim

1 . A vehicle control system for avoiding a collision between a right-turning vehicle and a straight-through vehicle,
wherein a first vehicle retains high-precision map data used to identify a lane in which the first vehicle is traveling, and wherein, when the first vehicle is in an autonomous driving mode and intends to travel in a right turn lane and turn right at an intersection ahead based on the high-precision map data, the first vehicle transmits a right turn notification indicating the intention to turn right, to one or more nearby vehicles using vehicle-to-vehicle communications; and wherein a second vehicle retains high-precision map data used to identify a lane in which the second vehicle is traveling, and wherein, when the second vehicle is in an autonomous driving mode and intends to travel straight at an intersection ahead, the second vehicle recognizes a different vehicle in an oncoming lane at the intersection as a right-turning vehicle upon receiving the right turn notification from the different vehicle, and performs a predetermined control for collision avoidance with the right-turning vehicle.

2 . A vehicle control system for avoiding a collision between a right-turning vehicle and a straight-through vehicle,
wherein a first vehicle retains high-precision map data used to identify a lane in which the first vehicle is traveling, and wherein, when the first vehicle is in an autonomous driving mode and intends to travel in a right turn lane and turn right at an intersection ahead based on the high-precision map data, the first vehicle transmits a right turn notification indicating the intention to turn right, to one or more nearby vehicles using vehicle-to-vehicle communications; and wherein, when a second vehicle is in a manual driving mode and receives the right turn notification from a different vehicle, the second vehicle performs a predetermined control for collision avoidance by notifying a driver of the second vehicle that there is the different vehicle in an oncoming lane intending to turn right at an intersection ahead.

3 . A vehicle control system for avoiding a collision between a right-turning vehicle and a straight-through vehicle,
wherein, when a first vehicle is in a manual driving mode and detects that a driver of the first vehicle operates a turn signal lever to give a right turn signal, the first vehicle transmits a right turn notification indicating the intention to turn right, to one or more nearby vehicles using vehicle-to-vehicle communications; and wherein a second vehicle retains high-precision map data used to identify a lane in which the second vehicle is traveling, and wherein, when the second vehicle is in an autonomous driving mode and intends to travel straight at an intersection ahead, the second vehicle recognizes a different vehicle in an oncoming lane at the intersection as a right-turning vehicle based on the right turn notification transmitted from the different vehicle and the high-precision map data, and performs a predetermined control for collision avoidance with the right-turning vehicle.

4 . The vehicle control system according to claim 1 , wherein, when there are multiple right turn lanes and the first vehicle intends to travel in a farthest right turn lane and turn right at an intersection ahead, the farthest right turn lane being one of the multiple right turn lanes which is farthest from the center of a road, the first vehicle transmits the right turn notification indicating the intention to turn right from the farthest right turn lane.

5 . The vehicle control system according to claim 3 , wherein, upon receiving the right turn notification, the second vehicle recognizes a different vehicle in a farthest oncoming lane as a right-turning vehicle based on the high-precision map data, the farthest oncoming lane being one of the oncoming lanes which is farthest from the center of the road, and performs the predetermined control for collision avoidance with the right-turning vehicle.

6 . The vehicle control system according to claim 1 , wherein, in a case where the second vehicle recognizes a different vehicle in the oncoming lane at the intersection ahead as a right-turning vehicle and the second vehicle is expected to pass through the intersection before the right-turning vehicle, when detecting that the right-turning vehicle has moved in the intersection, the second vehicle performs the predetermined control for collision avoidance with the right-turning vehicle.

7 . The vehicle control system according to claim 1 , wherein the second vehicle performs the predetermined control for collision avoidance by changing an action plan for autonomous driving of the second vehicle.

8 . The vehicle control system according to claim 1 , wherein the second vehicle performs a control for providing an alert to an occupant as the predetermined control for collision avoidance.
