Abstract
An exemplary cruise control system includes an application that integrates curvature speed control, speed limit control, and adaptive speed control and generates an optimized speed profile that is used to control the vehicle.
Claims20
A cruise control system, comprising:
- a positioning sensor configured to obtain a set of locations along a road;
- a distance sensor configured to measure a distance to a proximate vehicle from a controlled vehicle;
- a speed sensor configured to measure a speed of a proximate vehicle;
- a processor;
- and
- a memory having stored thereon computer-executable instructions comprising:
- a speed optimization application that, when executed by the processor, causes the processor to determine a speed profile, the speed profile comprising a set of speeds corresponding to the set of locations, wherein the speed profile is determined as a minimum of:
- a first sub-expression representing a time to move through the set of locations;
- a second sub-expression representing a longitudinal acceleration of the controlled vehicle at the set of locations;
- a third sub-expression representing a lateral acceleration of the controlled vehicle at the set of locations;
- and
- a fourth sub-expression representing an accumulated deviation from a traffic flow velocity.
