THIRD ORDER POLYNOMIAL-BASED COURSE PREDICTION FOR DRIVER ASSISTANCE FUNCTIONS

摘要

Methods and systems for performing vehicle driver assistance. One method includes determining, at a controller, whether the vehicle is steering toward a drive-straight state and when the vehicle is steering toward the drive-straight state, calculating, at the controller, a predicted course trajectory using a third order polynomial. The method also includes calculating, at the controller, the predicted course trajectory using a non-third-order function when the vehicle is not steering toward the drive-straight state. In addition, the method includes performing the driver assistance based on the predicted course trajectory.
