Abstract

A vehicle control apparatus for performing autonomous driving of a host vehicle. The vehicle control apparatus includes an operating section information acquisition unit configured to acquire operating section information that is information of an operating section in which vehicle stability control by brake control has been operated in a vehicle in autonomous driving in the past; an operation plan generation unit configured to generate an operation plan of autonomous driving of the host vehicle based on a preset target route and map information; and a vehicle controller configured to perform autonomous driving along the operation plan, wherein the operation plan generation unit generates the operation plan so that the host vehicle does not stop in the operating section.

First claim

What is claimed is:

1 . A vehicle control apparatus for performing autonomous driving of a host vehicle, the vehicle control apparatus comprising:
an operating section information acquisition unit configured to acquire operating section information which is information of an operating section in which vehicle stability control by brake control is operated in a vehicle during autonomous driving in the past; and an operation plan generation unit configured to generate an operation plan of autonomous driving of the host vehicle based on a preset target route, map information, and the operating section information; a vehicle controller configured to perform the autonomous driving according to the operation plan; and wherein the operation plan generation unit generates the operation plan so that the host vehicle does not stop in the operating section on the target route.

2 . The vehicle control apparatus according to claim 1 ,
wherein the operation plan generation unit generates the operation plan such that the host vehicle passes through the operating section at a constant speed.

3 . The vehicle control apparatus according to claim 1 ,
wherein the operation plan generation unit generates the operation plan in which the host vehicle passes through the operating section without acceleration or deceleration in the operating section due to acceleration until the host vehicle enters the operating section when the operating section is an uphill slope, and generates the operation plan in which the host vehicle passes through the operating section without acceleration or deceleration in the operating section when the operating section is a downhill slope.

4 . The vehicle control apparatus according to claim 1 ,
wherein the vehicle controller stops the host vehicle at a position offset to the left or right in a travelling lane with respect to a center of the travelling lane when the vehicle controller stops the vehicle within the operating section based on an external environment detected by an external sensor of the host vehicle during autonomous driving.

5 . The vehicle control apparatus according to claim 2 ,
wherein the vehicle controller stops the host vehicle at a position offset to the left or right in a travelling lane with respect to a center of the travelling lane when the vehicle controller stops the vehicle within the operating section based on an external environment detected by an external sensor of the host vehicle during autonomous driving.

6 . The vehicle control apparatus according to claim 3 ,
wherein the vehicle controller stops the host vehicle at a position offset to the left or right in a travelling lane with respect to a center of the travelling lane when the vehicle controller stops the vehicle within the operating section based on an external environment detected by an external sensor of the host vehicle during autonomous driving.

7 . The vehicle control apparatus according to claim 1 ,
wherein the operating section information is associated with weather information when the vehicle stability control is activated, and wherein the operation plan generation unit narrows down the operating section information according to current weather information and uses the narrowed down operating section information to generate the operation plan.

8 . The vehicle control apparatus according to claim 2 ,
wherein the operating section information is associated with weather information when the vehicle stability control is activated, and wherein the operation plan generation unit narrows down the operating section information according to current weather information and uses the narrowed down operating section information to generate the operation plan.

9 . The vehicle control apparatus according to claim 3 ,
wherein the operating section information is associated with weather information when the vehicle stability control is activated, and wherein the operation plan generation unit narrows down the operating section information according to current weather information and uses the narrowed down operating section information to generate the operation plan.
