Abstract
A method for avoiding a collision of a vehicle, an apparatus for performing the method, and a computer program avoid a collision with an object positioned at a rear side or a side of an ego vehicle, which is a blind zone area when the ego vehicle turns, to prevent a side collision accident which may occur in a blind zone up turning driving, and determines a collision risk based on prestored surrounding object information upon restarting a vehicle to prevent the side collision accident due to carelessness of a driver upon driving after restarting of the vehicle.
Claims12
A method for avoiding a collision of a vehicle, the method comprising:
- acquiring, when an ego vehicle turns, movement prediction path information for a side surface of the ego vehicle;
- acquiring surrounding object information for a surrounding object positioned near the ego vehicle;
- determining a collision risk between the ego vehicle and the surrounding object based on the movement prediction path information and the surrounding object information;
- and
- actuating a braking device of the ego vehicle when it is determined that there is the collision risk between the ego vehicle and the surrounding object,
- wherein the acquiring of the movement prediction path information is made by predicting a movement radius of the ego vehicle based on a sensor signal of the ego vehicle, and acquiring the movement prediction path information for each of a left surface and a right surface of the ego vehicle by using specification information of the ego vehicle based on the movement radius,
- wherein the determining of the collision risk is made by determining whether there is a risk that the ego vehicle will collide with the surrounding object in the future by using the surrounding object information for the surrounding object closest to the ego vehicle based on the movement prediction path information for each of a left surface and a right surface of the ego vehicle,
- wherein the determining of the collision risk is made by determining, when the surrounding object closest to the ego vehicle is positioned at a left side of the ego vehicle, whether there is the risk that the ego vehicle will collide with the surrounding object in the future based on the movement prediction path information and the surrounding object information for the left surface of the ego vehicle, and
- determining, when the surrounding object closest to the ego vehicle is positioned at a right side of the ego vehicle, whether there is the risk that the ego vehicle will collide with the surrounding object in the future based on the movement prediction path information and the surrounding object information for the right surface of the ego vehicle,
- wherein the determining of the collision risk is made by determining, when the surrounding object closest to the ego vehicle is positioned at the left side of the ego vehicle, whether there is the risk that the ego vehicle will collide with the surrounding object in the future based on the movement prediction path information and the surrounding object information for the left surface of the ego vehicle when the ego vehicle turns in a left direction, and determining that there is no collision risk without separately determining whether there is the risk that the ego vehicle will collide with the surrounding object in the future when the ego vehicle turns in a right direction, and
- determining, when the surrounding object closest to the ego vehicle is positioned at the right side of the ego vehicle, whether there is the risk that the ego vehicle will collide with the surrounding object in the future based on the movement prediction path information and the surrounding object information for the right surface of the ego vehicle when the ego vehicle turns in the right direction, and determining that there is no collision risk without separately determining whether there is the risk that the ego vehicle will collide with the surrounding object in the future when the ego vehicle turns in the left direction.

An apparatus comprising:
- a memory storing one or more programs for avoiding a collision of a vehicle;
- and
- one or more processors performing an operation of avoiding the collision of the vehicle according to one or more programs stored in the memory,
- wherein the processor acquires, when an ego vehicle, movement prediction path information for a side surface of the ego vehicle,
- acquires surrounding object information for a surrounding object positioned near the ego vehicle,
- determines a collision risk between the ego vehicle and the surrounding object based on the movement prediction path information and the surrounding object information, and
- actuates a braking device of the ego vehicle when it is determined that there is the collision risk between the ego vehicle and the surrounding object,
- wherein the processor predicts a movement radius of the ego vehicle based on a sensor signal of the ego vehicle, and acquires the movement prediction path information for each of a left surface and a right surface of the ego vehicle by using specification information of the ego vehicle based on the movement radius,
- wherein the processor determines whether there is the risk that the ego vehicle will collide with the surrounding object in the future by using the surrounding object information for the surrounding object closest to the ego vehicle based on the movement prediction path information for each of the left surface and the right surface of the ego vehicle,
- wherein the processor determines, when the surrounding object closest to the ego vehicle is positioned at a left side of the ego vehicle, whether there is the risk that the ego vehicle will collide with the surrounding object in the future based on the movement prediction path information and the surrounding object information for the left surface of the ego vehicle, and
- determines, when the surrounding object closest to the ego vehicle is positioned at a right side of the ego vehicle, whether there is the risk that the ego vehicle will collide with the surrounding object in the future based on the movement prediction path information and the surrounding object information for the right surface of the ego vehicle,
- wherein the processor determines, when the surrounding object closest to the ego vehicle is positioned at the left side of the ego vehicle, whether there is the risk that the ego vehicle will collide with the surrounding object in the future based on the movement prediction path information and the surrounding object information for the left surface of the ego vehicle when the ego vehicle turns in a left direction, and determines that there is no collision risk without separately determining whether there is the risk that the ego vehicle will collide with the surrounding object in the future when the ego vehicle turns in a right direction, and
- determines, when the surrounding object closest to the ego vehicle is positioned at the right side of the ego vehicle, whether there is the risk that the ego vehicle will collide with the surrounding object in the future based on the movement prediction path information and the surrounding object information on the right surface of the ego vehicle when the ego vehicle turns in the right direction, and determines that there is no collision risk without separately determining whether there is the risk that the ego vehicle will collide with the surrounding object in the future when the ego vehicle turns in the left direction.
