Claim Text:
1. A method for providing an optimal collision avoidance path for a host vehicle that may potentially collide with a target vehicle, said method comprising: providing off-line an optimization look-up table for storing on the host vehicle that includes a plurality of optimal vehicle braking or longitudinal decelerations and optimal distances based on a range of speeds of the host vehicle and coefficients of friction of a roadway surface; determining a current speed of the host vehicle during the potential collision; determining a coefficient of friction of a roadway surface on which the host vehicle is traveling during the potential collision; determining, using a microprocessor, an optimal longitudinal deceleration or braking of the host vehicle for the optimal path for the current speed of the host vehicle and the coefficient of friction of the roadway surface that the host vehicle is traveling on using the look-up table; determining an optimal lateral acceleration or steering of the host vehicle for the optimal path; providing the optimal braking and the optimal steering to the host vehicle to follow the optimal path to avoid the collision with the target vehicle; and performing steering and braking of the host vehicle based on the optimal braking and the optimal steering.
