Abstract

An autonomous driving vehicle includes an ECU configured to, when a lighting state is green lighting and a state has changed from a state where a host vehicle cannot pass an intersection to a state where the host vehicle can pass the intersection: cause the host vehicle that has stopped in front of the intersection to start moving and cause the host vehicle to travel with an acceleration or a vehicle speed limited to a second upper limit value smaller than a first upper limit value when there is a crossing oncoming vehicle; and cause the host vehicle to travel with the acceleration or the vehicle speed limited to a third upper limit value smaller than the second upper limit value when the crossing oncoming vehicle is a two-wheeled vehicle, the second upper limit value being used when the crossing oncoming vehicle is not a two-wheeled vehicle.

First claim

What is claimed is:

1 . An autonomous driving vehicle comprising:
a traffic light state recognition unit configured to recognize a lighting state of a traffic light at an intersection ahead of a host vehicle on an own lane based on a detection result of an in-vehicle external sensor; a space recognition unit configured to recognize a space between a vehicle ahead located beyond the intersection in a straight traveling direction of the host vehicle and the intersection based on the detection result of the external sensor; a passing determination unit configured to determine, based on the space, whether the host vehicle can pass through the intersection; and a vehicle control unit configured to stop the host vehicle in front of the intersection when the lighting state is green lighting and the host vehicle cannot pass through the intersection, wherein the vehicle control unit is configured to, when the lighting state is green lighting and a state has changed from a state where the host vehicle cannot pass the intersection to a state where the host vehicle can pass the intersection: cause the host vehicle that has stopped in front of the intersection to start moving and cause the host vehicle to travel with an acceleration or a vehicle speed of the host vehicle limited to a second upper limit value smaller than a first upper limit value when there is a crossing oncoming vehicle that is about to turn right or left at the intersection in such a manner as to cross the own lane, the first upper limit value being used when there is no crossing oncoming vehicle; and cause the host vehicle to travel with the acceleration or the vehicle speed of the host vehicle limited to a third upper limit value smaller than the second upper limit value when the crossing oncoming vehicle is a two-wheeled vehicle, the second upper limit value being used when the crossing oncoming vehicle is not a two-wheeled vehicle.

2 . The autonomous driving vehicle according to claim 1 , wherein the vehicle control unit is configured to: cause the host vehicle to travel with the acceleration or the vehicle speed of the host vehicle limited to the second upper limit value or the third upper limit value until the host vehicle goes by the crossing oncoming vehicle; and cause the host vehicle to travel with the acceleration or the vehicle speed of the host vehicle limited to the first upper limit value after the host vehicle goes by the crossing oncoming vehicle.
