Embodiment Construction
[0033] Referring to the drawings, wherein like reference numerals refer to like parts throughout the several views, in host vehicle 30 , controller 34 includes a processor and a memory storing processor-executable instructions. The processor is programmed to, upon confirming that the intersection angle β between the host vehicle 30 and the target vehicle is between a preset lower limit and an upper limit and the absolute value of the azimuth change rate dθ / dt of the host vehicle 30 is below a preset threshold, The target vehicle 32 is designated as a collision risk.
[0034] The controller 34 allows the host vehicle 30 to determine whether the target vehicle 32 is a collision risk, and if so, perform an evasive maneuver or warn the human driver that there is a collision risk. By relying on the intersection angle β and the azimuth rate of change dθ / dt, the controller 34 determines the risk of collision in a computationally efficient manner with a low amount of error and measure...
