Abstract

A direction indicator is configured to start blinking in response to an operation of a driver of a subject vehicle and automatically turn off after a first blinking time elapses. When the subject vehicle changes lanes in an automated or autonomous manner due to the operation of the driver, a control apparatus is used to extend the first blinking time to a second blinking time longer than the first blinking time and control the direction indicator to automatically turn off.

Claims

1. A method of controlling a direction indicator using a processor, comprising:

controlling a blinking time of the direction indicator being configured to start blinking in response to an operation of a driver of a subject vehicle and automatically turn off, wherein the blinking time is from a time the direction indicator starts blinking to a time the direction indicator automatically turns off;

determining whether an automated or autonomous lane change function is set,

wherein a lane change function is based on a first steering control by the driver or a second steering control by the automated or autonomous lane change function, and

wherein the automated or autonomous lane change function is a function of changing in an automated or autonomous manner from a lane in which the subject vehicle is traveling to another lane in response to the operation of the driver;

when it is determined that the automated or autonomous lane change function is not set, setting the blinking time of the direction indicator to a first blinking time; and

when it is determined that the automated or autonomous lane change function is set, setting the blinking time of the direction indicator to a second blinking time longer than the first blinking time.

2. The method of controlling the direction indicator according to claim 1, comprising:

when the subject vehicle changes lanes in the automated or autonomous manner, determining during the first blinking time whether or not the subject vehicle can change lanes, on a basis of a detection result of a first detector equipped in the subject vehicle to detect a situation around the subject vehicle; and

when determining that the subject vehicle can change lanes, extending the first blinking time to the second blinking time.

3. The method of controlling the direction indicator according to claim 1, comprising:

when the subject vehicle changes lanes in the automated or autonomous manner, determining during the first blinking time whether or not the driver has steered in a direction of a lane change, on a basis of a detection result of a second detector equipped in the subject vehicle to detect a direction of steering control performed by the driver; and

when determining that the driver has steered in the direction of the lane change, controlling the direction indicator to blink for the first blinking time from a time at which the driver has steered.

4. The method of controlling the direction indicator according to claim 2, comprising:

when the subject vehicle changes lanes in the automated or autonomous manner, determining during the first blinking time whether or not the driver has steered in a direction of a lane change, on a basis of a detection result of a second detector equipped in the subject vehicle to detect a direction of steering control performed by the driver; and

when determining that the driver has steered in the direction of the lane change, controlling the direction indicator to blink for the first blinking time from a time at which the driver has steered.

5. An apparatus for controlling a direction indicator, the apparatus comprising a processor operating to:

control a blinking time of the direction indicator being configured to start blinking in response to an operation of a driver of a subject vehicle and automatically turn off, wherein the blinking time is from a time the direction indicator starts blinking to a time the direction indicator automatically turns off;

determine whether an automated or autonomous lane change function is set,

wherein a lane change function is based on a first steering control by the driver or a second steering control by the automated or autonomous lane change function, and

wherein the automated or autonomous lane change function is a function of changing in an automated or autonomous manner from a lane in which the subject vehicle is traveling to another lane in response to the operation of the driver;

when it is determined that the automated or autonomous lane change function is not set, set the blinking time of the direction indicator to a first blinking time; and

when it is determined that the automated or autonomous lane change function is set, set the blinking time of the direction indicator to a second blinking time longer than the first blinking.
