Abstract

The present disclosure relate to a technology to detect an object placed in a blind spot on a road so as to inhibit collision between a target vehicle driving in the vicinity of a vehicle, and the object. The vehicle includes an imager to detect the object by recording the object near the vehicle, a sensor to obtain position information and speed information of the object, and a controller to calculate a time to collision (TTC) between the target vehicle and the object, based on the position information and/or speed information of the object. to the controller outputs a collision risk warning signal in a direction of the object, based on the calculated TTC.

First claim

What is claimed is:

1. A vehicle comprising:
an imager configured to detect an object in the vicinity of the vehicle;
a sensor configured to obtain at least one of position information or speed information of the object detected by the imager; and
a controller configured to:
when the imager is detecting the object using a motion detection function, determine whether the vehicle is in at least one of a parked state, a stopped state, or an ignition off state,
when the vehicle is in the ignition off state, activate the sensor,
calculate a time to collision (TTC) between a target vehicle driving in the vicinity of the vehicle and the object, based on the obtained position information or speed information of the object, and
output a collision risk warning signal in a direction of the object, based on the calculated TTC.

2. The vehicle of claim 1 , wherein the controller is further configured to transmit a driving speed control signal configured to cause a driving speed of the target vehicle to be controlled based on the calculated TTC.

3. The vehicle of claim 1 , wherein the controller is further configured to transmit, based on the calculated TTC, a braking control signal configured to assist the target vehicle to avoid a collision with the object.

4. The vehicle of claim 1 , wherein the controller is further configured to transmit, based on the calculated TTC, a target vehicle driver warning control signal configured to cause the target vehicle to output a warning to a driver of the target vehicle of the collision risk between the target vehicle and the object.

5. The vehicle of claim 1 , wherein the sensor is further configured to obtain at least one of position information or speed information of the target vehicle.

6. The vehicle of claim 1 , wherein the controller is further configured to generate the collision risk warning signal that is configured to cause a headlamp of the vehicle to emit light in the direction of the object.

7. The vehicle of claim 1 , wherein the controller is further configured to generate the collision risk warning signal that is configured to cause a speaker of the vehicle to output a sound signal regarding the target vehicle in the direction of the object.

8. The vehicle of claim 1 , wherein the controller is further configured to generate the collision risk warning signal that is configured to cause the operation of a turn signal lamp of the vehicle such that a driver of the target vehicle is warned of a collision risk between the object and the target vehicle.

9. The vehicle of claim 1 , wherein the controller is further configured to control a communicator to transmit the collision risk warning signal to the target vehicle.

10. The vehicle of claim 1 , wherein the sensor comprises at least one of a Radar sensor or a Light Detection And Ranging (LiDAR) sensor.

11. A control method of a vehicle comprising:
determining, by a controller, whether the vehicle is in at least one of a parked state, a stopped state, or an ignition off state when an imager is detecting an object using a motion detection function;
when the vehicle is in the ignition off state, activating, by the controller, a sensor;
detecting, by the imager, an object by recording the object in the vicinity of the vehicle;
obtaining, by the sensor, at least one of position information or speed information of the object;
calculating, by the controller, a time to collision (TTC) between a target vehicle driving in the vicinity of the vehicle and the object, based on the obtained position information or speed information of the object; and
transmitting, by the controller, a collision risk warning signal in a direction of the object, based on the calculated TTC.

12. The control method of claim 11 , further comprising:
transmitting, by the controller, a driving speed control signal configured to cause a driving speed of the target vehicle to be controlled, based on the calculated TTC.

13. The control method of claim 11 , further comprising:
transmitting, by the controller, a braking control signal to the target vehicle so as to avoid a collision between the target vehicle and the object, based on the calculated TTC.

14. The control method of claim 11 , further comprising:
transmitting, by the controller, a target vehicle driver warning control signal configured to cause the target vehicle to output a warning to a driver of the target vehicle of a collision risk between the target vehicle and the object, based on the calculated TTC.

15. The control method of claim 11 , further comprising:
obtaining, by the sensor, at least one position information or speed information of the target vehicle driving in the vicinity of the vehicle.

16. The control method of claim 11 , wherein the collision risk warning signal comprises a control signal warning of a collision risk, and the control signal is configured to cause a headlamp of the vehicle to emit light in the direction of the object.

17. The control method of claim 11 , wherein the collision risk warning signal comprises a control signal to warn of a collision risk, and the control signal is configured to cause a speaker of the vehicle to output a sound signal from the vehicle in the direction of the object.

18. The control method of claim 11 , wherein the collision risk warning signal comprises a control signal to warn a driver of the target vehicle of a collision risk between the object and the target vehicle, and the control signal is configured to cause the operation of a turn signal lamp of the vehicle.

19. The control method of claim 11 , further comprising:
transmitting the collision risk warning signal to the target vehicle.
