Mack Trucks announced its active steering system, Mack Command Steer, will be available for ordering in its Granite axle-back vocational models in the third quarter.

Mack Command Steer monitors terrain, driver inputs and environmental elements — including holes, dips and ruts — more than 2,000 times per second through sensors found throughout the truck. Based on that input, the system provides variable steering effort through its electric motor, which applies additional torque as needed to the steering, according to the Greensboro, N.C.-based unit of Volvo Group.

“Driving a fully loaded, heavy-duty construction truck is a physically demanding task, especially when you add the uneven terrain common to most job sites,” Roy Horton, Mack Trucks’ director of product strategy, said in a release. “With the added steering assist from Mack Command Steer, we are able to reduce driver effort by 85% and significantly improve driver productivity and job site safety.”

The feature also has a return-to-zero capability that automatically returns the steering wheel to the zero, or center, position in forward and reverse. This helps simplify tight maneuvers, such as backing a trailer or positioning a dump or mixer to unload. — Transport Topics
