Abstract
Official abstract text for this publication.
A system and method for providing an optimal collision avoidance path for a host vehicle that may potentially collide with a target vehicle. The method includes providing off-line an optimization look-up table for storing on the host vehicle that includes an optimal vehicle braking or longitudinal deceleration and an optimal distance along the optimal path based on a range of speeds of the host vehicle and coefficients of friction of the roadway surface. The method determines the current speed of the host vehicle and the coefficient of friction of the roadway surface during the potential collision, and uses the look-up table to determine the optimal longitudinal deceleration or braking of the host vehicle for the optimal vehicle path. The method also determines an optimal lateral acceleration or steering of the host vehicle for the optimal vehicle path based on a friction ellipse and the optimal braking.
First claim
Opening claim text (preview).
