Mack® Predictive Cruise Control with Econo-Roll Now Standard on Mack Highway Models
GREENSBORO, NC (Jan. 25, 2022) – Mack Trucks once again highlighted its commitment to the highway trucking segment by announcing that Mack® Predictive Cruise Control with Econo-Roll is now standard on Mack Anthem® and Mack Pinnacle™ models.
Mack Predictive Cruise combines the Mack mDRIVE™ automated manual transmission (AMT) with GPS, monitoring driver speed, engine load and road topography, memorizing those conditions when cruise control is set. The next time the driver travels the same route, Mack Predictive Cruise will communicate to the transmission to ensure the optimal gear for fuel efficiency is chosen.
“Predictive Cruise is truly an engineering feat as it uses the knowledge gained from past routes to automatically adjust speed and torque when the route is again driven,” said Stu Russoli, Mack highway product manager. “The system can store up to 4,500 routes, offers maximum fuel efficiency and improves total cost of ownership for customers.”
Mack Predictive Cruise can increase fuel efficiency by up to 1 percent and does not require a constant GPS connection. After a short connection to GPS, Mack Predictive Cruise recognizes the hill, sends the communication to mDRIVE, which automatically knows the optimal speed and gear strategy for the upcoming terrain.
Mack Predictive Cruise constantly monitors speed, engine load, weight and the road gradient in order to select the best gear for the road ahead. When approaching a hill, Predictive Cruise allows slightly more speed. The mDRIVE AMT then maintains the highest gear possible, remaining in that gear and preventing downshifts if unnecessary to crest the hill. Econo-Roll, which temporarily disengages the driveline before the downhill descent, allows the truck to roll, reducing fuel consumption.
When traveling downhill, Mack Predictive Cruise maintains vehicle speed, utilizing kinetic energy and softly applying the engine brake. Because the hill is stored in the vehicle’s memory, Predictive Cruise recognizes it and knows when the gradient will even out, allowing the truck to maintain its speed for the next incline.
