Abstract
An anticipatory speed-control system and method for generating a speed profile in real time by iteratively calculating proposed reduced speeds associated with an electronically identified target curve until the proposed speed is compliant with a lateral-acceleration-based comfort metric and a steering-angle-based safety metric and implementing the speed profile in accordance with a longitudinal comfort metric and providing a user with override options.
