Abstract

An apparatus and a method for warning in a vehicle generates a warning based on a distance in order to avoid a problem that may occur when a collision warning is generated based on only a time required for a collision. The method of generating a warning in a vehicle includes: obtaining a distance and a relative speed of the vehicle to a target vehicle ahead; obtaining a time required for a collision with the target vehicle from the distance and the relative speed; and generating a warning when at least one of a first condition in which the time required for the collision is equal to or less than a predetermined warning generation time and a second condition in which the distance is equal to or less than a predetermined warning generation distance is satisfied.

First claim

What is claimed is:

1. A method of generating a warning in a vehicle, the method comprising:
obtaining a distance and a relative speed of the vehicle to a target vehicle ahead;
obtaining a time required for a collision with the target vehicle from the distance and the relative speed; and
generating a warning if at least one of a first condition, in which the time required for the collision is equal to or less than a predetermined warning generation time, and a second condition, in which the distance is equal to or less than a predetermined warning generation distance is satisfied.

2. The method according to claim 1 , wherein generating a warning according to the second condition comprises generating the warning every time the target vehicle is within a predetermined ratio of a previous warning generation distance.

3. The method according to claim 2 , wherein the warning is generated for a predetermined time every time the target vehicle is within the predetermined ratio of the previous warning generation distance.

4. The method according to claim 2 , wherein the predetermined time is within two seconds.

5. The method according to claim 2 , wherein the predetermined ratio is within 60%.

6. An apparatus for generating a warning in a vehicle, the apparatus comprising:
a sensor for detecting a presence of a target vehicle ahead; and
a controller for obtaining a distance and a relative speed of the vehicle to the target vehicle, obtaining a time required for a collision with the target vehicle from the distance and the relative speed, generating a warning if at least one of a first condition, in which the time required for the collision is equal to or less than a predetermined warning generation time, and a second condition, in which the distance is equal to or less than a predetermined warning generation distance is satisfied.

7. The apparatus according to claim 6 , wherein the controller is configured to generate the warning every time the target vehicle is within a predetermined ratio of a previous warning generation distance when generating a warning according to the second condition.

8. The apparatus according to claim 7 , wherein the controller is configured to generate the warning for a predetermined time every time the target vehicle is within the predetermined ratio of the previous warning generation distance.

9. The apparatus according to claim 7 , wherein the predetermined time is within two seconds.

10. The method according to claim 7 , wherein the predetermined ratio is within 60%.

11. A method of generating a warning in a vehicle, the method comprising:
obtaining a distance to a target vehicle ahead; and
generating a warning when the distance is equal to or less than a predetermined warning generation distance,
wherein the warning is generated every time the target vehicle is within a predetermined ratio of a previous warning generation distance.

12. The method according to claim 11 , wherein the warning is generated for a predetermined time every time the target vehicle is within the predetermined ratio of the previous warning generation distance.

13. A method of generating a warning in a vehicle, the method comprising:
obtaining a distance and a relative speed of the vehicle to a target vehicle ahead;
obtaining a time required for a collision with the target vehicle from the distance and the relative speed; and
generating a warning if at least one of a first condition, in which the time required for the collision is equal to or less than a predetermined warning generation time, and a second condition, in which the distance is equal to or less than a predetermined warning generation distance is satisfied,
wherein the warning is generated every time the target vehicle is within a predetermined ratio of a previous warning generation distance.

14. The method according to claim 13 , wherein the warning is generated for a predetermined time the target vehicle is within the predetermined ratio of the previous warning generation distance.
