Abstract

A vehicle and a method for controlling a vehicle detects an object for avoiding a collision between a vehicle and the object, based on a type of the object detected by the vehicle, and determining a risk of collision with the object. The vehicle includes an image capturer configured to detect an object by capturing the object around a vehicle, a sensor configured to acquire at least one of position information and speed information of the object, a controller configured to variably determine a detection target area based on the type of the detected object, configured to calculate a time to collision (TTC) between the vehicle and the object based on the at least one of position information and speed information of the object placed in the determined detection target area, and configured to transmit a signal to control a driving speed of the vehicle based on the calculated TTC, and a speed regulator configured to regulate the driving speed of the vehicle in response to the transmitted control signal.

First claim

What is claimed is:

1. A vehicle comprising:
an image capturer configured to detect an object by capturing the object around a vehicle;
a sensor configured to acquire at least one of position information or speed information of the object;
a controller configured to variably determine a detection target area based on a type of the detected object, configured to calculate a time to collision (TTC) between the vehicle and the object based on the at least one of position information or speed information of the object located in the variably determined detection target area, and configured to transmit a signal to control a driving speed of the vehicle based on the calculated TTC; and
a speed regulator configured to regulate the driving speed of the vehicle in response to the transmitted control signal,
wherein the controller is configured to determine an area of the detection target area based on at least one of a speed of lateral movement of the object or a speed of longitudinal movement of the object based on the type of the detected object.

2. The vehicle of claim 1 , wherein
the controller determines the detection target area based on at least one of a speed of lateral movement or a speed of longitudinal movement based on the type of the detected object.

3. The vehicle of claim 1 , wherein
the controller calculates the TTC between the vehicle and the object based on the at least one of position information or speed information of the object located in the determined detection target area.

4. The vehicle of claim 3 , wherein
the controller calculates the TTC between the vehicle and the object based on at least one of the speed of lateral movement or the speed of longitudinal movement of the object located in the determined detection target area.

5. The vehicle of claim 1 , wherein
the controller determines an amount of deceleration of the vehicle based on the calculated TTC.

6. The vehicle of claim 5 , wherein
the controller controls the speed regulator so that the driving speed of the vehicle is reduced based on the determined amount of deceleration of the vehicle.

7. The vehicle of claim 1 , wherein
the object comprises at least one of a target vehicle, a pedestrian or a bicycle located in front of the vehicle.

8. The vehicle of claim 1 , wherein
the sensor comprises any one of a radar and a Light Detection And Ranging (LiDAR).

9. A method for controlling a vehicle comprising:
detecting an object around a vehicle;
variably determining a detection target area based on a type of the detected object;
calculating-a time to collision (TTC) between the vehicle and the object based on at least one of position information or speed information of the object located in the variably determined detection target area;
transmitting a signal to control a driving speed of the vehicle based on the calculated TTC; and
regulating the driving speed of the vehicle in response to the transmitted control signal,
wherein the variably determining of the detection target area comprises determining an area of the detection target area based on at least one of a speed of lateral movement of the object or a speed of longitudinal movement of the object based on the type of the detected object.

10. The method of claim 9 , wherein
the determination of the detection target area comprises determining the detection target area based on at least one of a speed of lateral movement or a speed of longitudinal movement based on the type of the detected object.

11. The method of claim 9 , wherein
the calculation of the TTC between the vehicle and the object comprises calculating a TTC between the vehicle and the object based on the at least one of position information or speed information of the object located in the determined detection target area.

12. The method of claim 11 , wherein
the calculation of the TTC between the vehicle and the object comprises calculating a TTC between the vehicle and the object based on at least one of the speed of lateral movement or the speed of longitudinal movement the object located in the determined detection target area.

13. The method of claim 9 , wherein
the control of the driving speed of the vehicle comprises determining an amount of deceleration of the vehicle based on the calculated TTC.

14. The method of claim 13 , wherein
the control of the driving speed of the vehicle comprises allowing the driving speed of the vehicle to be reduced based on the determined amount of deceleration of the vehicle.
