International Introduces Predictive Cruise Control for ProStar, LoneStar Models
International Truck, a brand of Navistar International Corp., announced that it now offers predictive cruise control technology as an option on its ProStar and LoneStar Class 8 on-highway models to improve fuel efficiency and driver retention.
The system will monitor driver speed, engine load, weight and road grade to optimize the vehicle’s performance based on the road ahead, according to the company.
Unlike conventional predictive cruise technology, International's predictive cruise control uses preinstalled GPS maps and the latest commercial route data to make adjustments to cruising speed without the need to pre-drive the route, the company said.
“We’re seeing data indicating that this technology can increase fuel efficiency by up to 4%, depending on loads and routes. And on some very, very hilly routes we have seen higher savings,” said Denny Mooney, Navistar’s senior vice president, global product development.
Mooney spoke during a conference call to discuss the new feature.
He said International spent two years developing the needed control-module algorithms and software using both a computer-based simulation process called ‘hardware in the loop’ as well as actual road tests of the trucks.
The system uses mapping software from Navtech, Mooney said.
The pre-programed map covers the major U.S. highway systems “where you are going to get most of the truck traffic,” he said. “I envision we will upgrade the software to continue to get as many road systems as we can in it.”
