Patent ID: 7774121

Claim:
A curve speed control system for controlling the speed of a vehicle traveling on a curve, said system comprising: a map database storing information about road curves that the vehicle may be traveling through, said map database including a map database processor that includes curvature information about the curves; a curvature profile processor responsive to the curvature information from the map processor and providing a curvature profile as a series of curvature data points from the curvature information of the curve, said curvature profile processor determining when to provide the curvature profile based on the vehicle speed; a desired speed profile processor responsive to the curvature profile from the curvature profile processor, said desired speed profile processor providing a desired speed for each curvature profile point and providing a desired speed profile; a driver mode selector that provides a driver mode value based on driver aggressiveness; an acceleration profile processor that receives the desired speed profile from the desired speed profile processor, a vehicle speed signal and the driver mode value, said acceleration profile processor providing a performance index function based on the difference between the vehicle speed, the desired speed and the driver mode value; and an acceleration command processor for providing an acceleration command that controls the speed of the vehicle based on the performance index function.
