PREDICTIVE CRUISE CONTROL (PCC)
- Vehicle speed to:
- Maximize fuel economy
- Arrive at the destination in the same amount of time as without PCC, by driving both faster and slower during portions of the route
- Vehicle speed by:
- Using road grade map data, GPS, engine load, and tractor trailer weight
- Desired vehicle speed by:
- Accelerating before ascents to avoid downshifts
- Decelerating before descents to minimize engine brake use
- Operating as standard cruise control on flat land
- GPS antenna is located at a high point on the back of the cab for maximum signal strength.
- Driver turns the cruise control on and sets cruising speed.
- Programmable parameters manage the maximum vehicle speed changes above and below the speed set by the driver.
DRIVER EXPERIENCE USING PREDICTIVE CRUISE CONTROL (PCC)
- Adjusts for upcoming road grade based on driver’s cruise control set speed and vehicle weight to maximize fuel economy and arrive at the destination in the same amount of time.
- Example shown with typical programmable parameters allowing up to +/-3 mph. Programmable parameters can allow up to +5 / -10 mph.
- Programmable parameters can be reprogrammed by the fleet with Navistar Engine Diagnostics for A26 and with Cummins Insite forX15.

FREQUENTLY ASKED QUESTIONS
Will the driver lose time using Predictive Cruise Control?
- Predictive Cruise Control maximizes vehicle speed (both faster and slower based on the route hill variations) allowing the driver to arrive at the destination in the same amount of time as Standard Cruise Control.
How does Predictive Cruise Control know the road ahead?
- PCC uses preinstalled GPS maps and the latest commercial route data to make adjustments to cruising speed without the need to “pre-drive” routes. Because the GPS maps and route data are already loaded, this smart technology enables fleets and drivers to obtain greater fuel efficiency right out of the box. As a result, drivers who frequently run different routes will experience the same benefit as drivers who are used to driving a standard route.
What is Adaptive Cruise Control?
- Adaptive Cruise Control uses forward facing radar, and in some instances an additional forward facing camera, to monitor for objects ahead and reduce vehicle speed to maintain a safe following distance.
How Does Predictive Cruise Control work with Adaptive Cruise Control?
- When there IS a safe following distance, the vehicle will use the Predictive Cruise Control system to maximize fuel economy.
- When there is NOT a safe following distance, the vehicle will use the Adaptive Cruise Control system to reduce vehicle speed.
What happens if the vehicle loses the GPS signal?
- The vehicle will return to the speed set by the driver.
