Classification: CPC B  G | IPC B  G

Claim 0:
1. A vehicle collision avoidance method comprising:
receiving host vehicle driving information comprising position coordinates and a driving direction of a host vehicle;
receiving remote vehicle driving information comprising position coordinates and a driving direction of a remote vehicle;
generating a host vehicle position function and a remote vehicle position function based on the host vehicle driving information and the remote vehicle driving information;
setting a transformation coordinate system with respect to the position coordinates of the host vehicle;
calculating a rotation angle that is an angle between the driving direction of the host vehicle and one axis of the transformation coordinate system;
transforming the host vehicle position function and the remote vehicle position function to a transformed host vehicle position function and a transformed remote vehicle position function, respectively, using the rotation angle;
determining a collision possibility between the host vehicle and the remote vehicle using the transformed host vehicle position function and the transformed remote vehicle position function; and
controlling the host vehicle depending on the collision possibility.
