Abstract

Method and apparatus for a vehicle cruise control, particularly concerning a school bus, which includes collecting information on the school bus and a road environment positioned around nearby vehicle, monitoring position, velocity and moving direction of the school bus, and state of surrounding road. If the school bus is stopped relatively near the front of the nearby vehicle, the method continues by determining whether or not the vehicle is stopped by comparing the collected school bus information and the road environment information with a predefined cruise regulation based on the school bus, and guiding the driver to stop as well as controlling the vehicle to stop depending on the determination result.

First claim

What is claimed is:

1. A method for a cruise control based on a school bus, the method comprising:
collecting information on the school bus and a road environment which are positioned around a vehicle;
monitoring a position, a velocity and a moving direction of the school bus, and a state of surrounding road;
if the school bus is stopped relatively near the front of the vehicle, determining whether or not the vehicle is stopped by comparing the collected school bus information and road environment information with a predefined cruise regulation based on the school bus; and
guiding a driver to stop and controlling the vehicle to stop depending on the determination result,
wherein, in the determining of whether or not the vehicle is stopped, if the moving direction of the school bus is the same as a moving direction of the vehicle, it is determined that the vehicle is stopped.

2. The method according to claim 1 , wherein, in the determining of whether or not the vehicle is stopped, if the school bus is stopped in the same lane as that of the vehicle or a next lane thereof, it is determined that the vehicle is stopped.

3. A method for a cruise control based on a school bus, the method comprising:
collecting information on the school bus and a road environment which are positioned around a vehicle;
monitoring a position, a velocity and a moving direction of the school bus, and a state of surrounding road;
if the school bus is stopped relatively near the front of the vehicle, determining whether or not the vehicle is stopped by comparing the collected school bus information and road environment information with a predefined cruise regulation based on the school bus; and
guiding a driver to stop and controlling the vehicle to stop depending on the determination result,
wherein, in the determining of whether or not the vehicle is stopped, if the moving direction of the school bus is opposite to a moving direction of the vehicle, it is determined whether or not the vehicle is stopped depending on the state of surrounding road.

4. The method according to claim 3 , wherein, in determining whether or not the vehicle is stopped, if a centerline is not present on a corresponding road, it is determined that the vehicle is stopped.

5. The method according to claim 3 , wherein, in determining whether or not the vehicle is stopped, if the moving direction of the school bus is opposite to a moving direction of the vehicle, it is determined whether or not the vehicle is stopped depending on the number of lanes on a corresponding road.

6. The method according to claim 5 , wherein, in determining whether or not the vehicle is stopped, if the corresponding road is a double lane, it is determined that the vehicle is stopped.

7. The method according to claim 3 , wherein, in determining whether or not the vehicle is stopped, if the moving direction of the school bus is opposite to a moving direction of the vehicle, it is determined whether or not the vehicle is stopped depending on whether or not a median strip is present on a corresponding road and on a height of the median strip.

8. The method according to claim 7 , wherein, in determining whether or not the vehicle is stopped, if the median strip is not present on the corresponding road, it is determined that the vehicle is stopped.

9. The method according to claim 7 , wherein, in determining whether or not the vehicle is stopped, if the height of the median strip disposed on the corresponding road is less than a reference value, it is determined that the vehicle is stopped.

10. A method for a cruise control based on a school bus, the method comprising:
collecting information on the school bus and a road environment which are positioned around a vehicle;
monitoring a position, a velocity and a moving direction of the school bus, and a state of surrounding road;
if the school bus is stopped relatively near the front of the vehicle, determining whether or not the vehicle is stopped by comparing the collected school bus information and road environment information with a predefined cruise regulation based on the school bus; and
guiding a driver to stop and controlling the vehicle to stop depending on the determination result,
wherein, in controlling of the vehicle to stop, the vehicle is controlled to maintain a stopped state until the school bus, which is stopped at the front of the vehicle, starts a cruise.

11. An apparatus for a cruise control based on a school bus, the apparatus comprising:
a surrounding environment monitor configured to collect information on the school bus and a road environment which are positioned around a vehicle and to monitor a position, a velocity and a moving direction of the school bus, and a state of surrounding road;
a determiner configured to determine whether or not the vehicle is stopped by comparing the collected school bus information and road environment information with a predefined cruise regulation based on the school bus if the school bus is stopped relatively at the front of the vehicle; and
a cruise controller configured to guide the stop to a driver and to control the vehicle to automatically stop or maintain a cruise state depending on the determination result of the determiner,
wherein the determiner determines whether or not the vehicle is stopped depending on the state of surrounding road when the moving direction of the school bus is opposite to a moving direction of the vehicle, and
wherein the determiner determines that the vehicle is stopped when the moving direction of the school bus is the same as a moving direction of the vehicle.

12. The apparatus according to claim 11 , wherein the surrounding environment monitor collects the school bus information and the road environment information from at least one of a sensor, navigation, and a communicator which are included in the vehicle.

13. The apparatus according to claim 12 , wherein the sensor includes at least one of a lidar, a radar, and a camera.

14. The apparatus according to claim 12 , wherein the communicator receives information on the school bus and the road environment which are positioned around the vehicle through communication with at least one of surrounding vehicles, roadside devices, and a control center.
