Theory of Operation

WARNING: This page is about a different car, the 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

While in cruise control, this monitor verifies that vehicle speed stays within 5 MPH (8 KPH) of cruise control setpoint. The monitor will abort if during this condition engine speed is decreasing by more than 13 RPM/second. This is meant to detect a condition when the vehicle is travelling downhill as that could cause an increase in overall vehicle speed. This monitor will abort if the driver goes out of cruise mode by pressing the brake or accelerator pedal. Cruise will be disabled the rest of the drive cycle (until key off).
