Abstract
An autonomous travel controller detects whether a host vehicle is carrying out a first course change for changing a course in a direction indicated by a turn indicator. Upon detecting that the host vehicle is carrying out the first course change, detecting whether there is a road that enables a second course change for changing the course of the host vehicle that branches from the road after the first course change. When a road that enables the second course change is detected, the autonomous travel controller turns the turn indicator off.
Claims5
A vehicle control method for turning off a blinking of a turn indicator that indicates a direction of a change of course of a host vehicle, the vehicle control method comprising:
- using a controller, the controller being operatively connected to the turn indicator, a vehicle sensor of the host vehicle, and a front camera of the host vehicle, to execute
- detecting, based on a detection result of the vehicle sensor, whether the host vehicle is carrying out a first course change for changing a course in a direction indicated by the turn indicator;
- upon detecting that the host vehicle is carrying out the first course change, detecting whether there is a boundary line that separates roads before and after the first course change,
- upon detecting the boundary line, determining whether the host vehicle has passed the boundary line, and turning the turn indicator off upon determining that the host vehicle has passed the boundary line, and
- upon detecting that the host vehicle is carrying out the first course change and determining that the boundary line is not detected, detecting, based on an image captured by the front camera, whether there is a road that enables a second course change for changing the course of the host vehicle that branches from the road after the first course change, and turning the turn indicator off upon detecting the road that enables the second course change based on the image captured by the front camera.
A vehicle control device comprising:
- a turn indicator that indicates a direction of a change of course of a host vehicle by blinking;
- a vehicle sensor that detects a course change of the host vehicle and the direction of the course change;
- a front camera disposed on the host vehicle and arranged to photograph an area ahead of the host vehicle;
- and
- a controller configured to turn off the turn indicator,
- the controller being configured to
- detect whether the host vehicle is carrying out a first course change for changing the course in a direction indicated by the turn indicator based on a detection result of the vehicle sensor,
- upon detecting that the host vehicle is carrying out the first course change, detect whether there is a boundary line that separates roads before and after the first course change,
- upon detecting the boundary line, determine whether the host vehicle has passed the boundary line and turn the turn indicator off upon determining that the host vehicle has passed the boundary line, and
- upon detecting that the host vehicle is carrying out the first course change and determining that the boundary line is not detected, detect, based on an image captured by the front camera to detect, whether there is a road that enables a second course change for changing the course of the host vehicle that branches from the road after the first course change, and turn off the turn indicator when the road that enables the second course change is detected based on the image captured by the front camera.
