Abstract
A failure detection and correction function which is able to detect a failure of an automatic braking system, and provide a corrected action. The failure detection and correction function is independent of the automatic braking function. The failure detection and correction function uses object coordinates and the speed of the vehicle to determine the collision risk, and then calculates a desired deceleration if there is imminent collision. The function uses desired deceleration to compare to a deceleration request from automatic braking function to determine if there is a failure. The failure detection and correction function takes corrected action to avoid the collision if the automatic braking function has failed.
