KENWORTH PREDICTIVE CRUISE UPDATE UPS FUEL ECONOMY

Posted: February 6, 2017 in Kenworth

Kenworth has updated its Predictive Cruise Control functionality for T680 and T880 trucks equipped with the 2017 Paccar MX-11, MX-13, and Cummins X15 engines to improve fuel economy.  The update was made with the launch of the 2017 emission engines and provides up to a 1% improvement in fuel economy over the current versions with Predictive Cruise Control, according to Patrick Dean, Kenworth chief engineer.  Kenworth’s Predictive Cruise Control combines GPS with cruise control to deliver the best fuel economy for the situation.  The system optimizes cruising speed based on topographical GPS data inputs.   As the truck encounters certain types of terrain, such as rolling hills, the system modulates cruising speed to improve performance.  If, for example, a truck ascends and crests a hill, Predictive Cruise Control will allow the truck speed to drop slightly below the set cruise speed.  This can improve fuel economy since the truck is using momentum instead of fuel to maintain the set cruise speed.  “While the drive interface remains  unchanged, drivers who have driven Kenworth trucks with Predictive Cruise Control will notice an improvement in drivability, as well as fuel economy,” said Dean.  “Improved drivability and fuel economy were made possible by fine-tuning how the engine modulates speed and torque over a wide variety of actual driving conditions.”
