Vehicle sensor information screening method and vehicle collision avoidance system applying same

The invention discloses a vehicle sensor information screening method and solves the problem that a real obstacle is difficult to distinguish automatically when the vehicle makes a turn. A coordinate system taking the horizontal offset of the vehicle as the value of y and the longitudinal offset of the vehicle as the value of x is built in the area s; the coordinate set A1 (y, x) of the obstacle in the front area s of the vehicle is acquired by a sensor; the current yaw rate r of the vehicle and the vehicle speed v are acquired by the sensor, the expected traveling track y' of the vehicle is generated, that is y'=f1(v, r, x), the horizontal deviation value y1=f2(x) is introduced according to the increase of the longitudinal distance, the expected position range ys'=f1(v, r, x)+-f2(x) of the turning process of the vehicle is generated, and the expected position set A2(ys', x) of the turning process of the vehicle is obtained accordingly; an intersection B of the A1 and the A2 is screened as a deterrent, the relative distance and the relative speed of the deterrent to the vehicle are obtained, and the vehicle sensor information screening method aims to screen the real deterrent in the turning process of the automobile.
