RULE-BASED CRUISE CONTROL SYSTEM AND METHOD
First Claim
1. A system comprising a computer in a vehicle, the computer comprising a processor and a memory, wherein the computer is configured to:
- control a vehicle speed within a first speed threshold according to a set point inputted to a cruise control system;
determine a current grade value is within a first grade threshold;
adjust the set point to control the vehicle speed within a second speed threshold outside the first speed threshold;
determine the current grade value is within a second grade threshold; and
adjust the set point to recover the vehicle speed to within the first speed threshold.

Abstract
A rule-based vehicle cruise-control system includes a computer in a vehicle, the computer including a processor and a memory, and the computer is configured to control a vehicle speed within a first speed threshold according to a set point inputted to the cruise control system. The computer is configured to determine a current grade value is within a first grade threshold and adjust the set point to control the vehicle speed within a second speed threshold outside the first speed threshold. The computer is further configured to determine the current grade value is within a second grade threshold and adjust the set point to recover the vehicle speed to within the first speed threshold.
