Peterbilt Debuts New Predictive Cruise Technology

Peterbilt is debuting its new Predictive Cruise technology, which automatically optimizes engine and transmission operation when in cruise control for maximum fuel economy, at MATS.

According to Darrin Siver, Peterbilt General Manager and PACCAR Vice President, “By integrating the powertrain, cruise control and satellite mapping, the vehicle automatically responds to the road ahead for up to three percent improved fuel economy.”

Predictive Cruise includes the neutral coasting feature. Neutral coasting utilizes the truck’s momentum to save fuel and engages the engine brake to manage downhill speeds.

Noted Peterbilt Chief Engineer Scott Newhouse, Predictive Cruise and neutral coast work together in five steps to maximize the truck’s kinetic energy:

1. When approaching a hill, the system uses onboard maps and GPS data to accelerate to the optimal speed and adjust for the increasing road grade;
2. Before the peak of the incline, the vehicle curbs its speed before proceeding downhill;
3. Neutral coast engages as the truck rolls downhill;
4. If necessary, the engine brake engages to avoid over speeding; and
5. Cruising speed is maintained as the vehicle continues onto level terrain.
