Abstract:
1. A back propagating intersection collision avoidance system for preventing two vehicles from colliding at an intersection, said system comprising: a first vehicle and a second vehicle, said first and second vehicle each operable to approach the intersection at a definable velocity and acceleration, said intersection having a collision zone in which said first and second vehicle will collide if present at a same time; said first vehicle having a processing unit with controller and a microprocessor with an algorithm, said algorithm having a disturbance model and said processing unit operable to back propagate from said collision zone a capture set as a function of a disturbance for said first and second vehicle, determine if said first and second vehicle is within said capture set, and if not, determine if said first and second vehicle will enter said capture set, said capture set covering control scenarios as a function of maximum torque and minimum torque of said first vehicle; said processing unit also operable to instruct said controller to accelerate or de-accelerate said first vehicle in order to prevent said first vehicle from entering said capture set.
