Cruise control systems and methods with adaptive speed adjustment rates
First Claim
1. A method for performing cruise control in a motor vehicle, the method comprising the steps of:
- determining a route which the motor vehicle is following;
receiving signals from at least one external infrastructure component;
determining a geographical location along the route of the motor vehicle based on the signals;
determining an upcoming geographical feature based on the geographical location along the route of the motor vehicle;
determining at least one of an acceleration plan and a deceleration plan based on the upcoming geographical feature;
receiving information relating to features of the route which the motor vehicle is following from a vehicle-to-infrastructure communication system interface;
wherein the determining the upcoming geographical feature is based on the information relating to the features; and
performing a cruise control procedure to adjust the speed of the vehicle based on the at least one of the acceleration plan and the deceleration plan.

Abstract
Embodiments include methods and apparatus for performing cruise control in a motor vehicle. Signals are received (e.g., by a positioning system interface) from at least one external infrastructure component, and a geographical location of the motor vehicle is determined (e.g., by a processing and control subsystem) based on the signals. A determination is made whether a difference between a target speed and an actual vehicle speed exceeds a threshold and, when the difference exceeds the threshold, a cruise control procedure is performed to maintain a target speed of the motor vehicle. Performing the cruise control procedure includes determining, based on the geographical location, whether the motor vehicle should adjust its speed toward the target speed.
