1. A control module-implemented method to selectively prevent a vehicle from resuming a vehicle set speed stored in memory of a cruise control system, comprising:
- the control module configured to execute the following steps, comprising;
monitoring a vehicle speed;
monitoring an accumulated distance traveled by the vehicle when the vehicle speed is within a low speed range;
only when the vehicle speed no longer remains within the low speed range for an elapsed time period exceeding a maximum low speed violation time threshold, resetting the monitored accumulated travel distance until the monitored vehicle speed is within the low speed range;
only when the vehicle speed is within the low speed range;
comparing the accumulated distance to a minimum travel distance; and
only when the accumulated distance exceeds the minimum travel distance, monitoring a vehicle turning maneuver; and
only when the vehicle speed is less than a predetermined vehicle speed threshold, wherein the predetermined vehicle speed threshold is greater than an upper limit of the low speed range;
comparing the accumulated distance to a threshold slow zone maximum distance; and
only when the accumulated distance does not exceed the threshold slow zone maximum distance, comparing the vehicle turning maneuver to a threshold slow zone maneuver; and
selectively preventing resumption of the vehicle set speed if the vehicle turning maneuver exceeds the threshold slow zone maneuver.

Abstract
A method to selectively prevent a vehicle from resuming a vehicle set speed stored in memory of a cruise control system includes monitoring a vehicle speed, determining that the vehicle speed indicates operation in a low speed range, determining a threshold slow zone maneuver based upon the vehicle speed substantially remaining in the low speed range through a predetermined duration, and inhibiting resumption of the vehicle set speed based upon the threshold slow zone maneuver.
