“This patented technology benefits the truck driver in all operating conditions. On the highway the dynamic steering system offers unbeatable directional stability. At low speeds even a heavily loaded truck is so easy to steer that you can do so with one finger,” says Claes Nilsson, President Volvo Trucks.
An electronically controlled electric motor attached to the steering shaft is the big new technological innovation in Volvo Dynamic Steering. The electric motor, which works together with the truck’s hydraulic power steering, has a maximum of 25 Nm of torque and is regulated thousands of times per second by the electronic control unit.
“The task of the electric motor is to deliver perfect steering feel for every single moment of operation. For instance, the system’s sensors note that the driver wants to drive straight ahead and automatically ensures that no interference from the road surface is allowed to filter up through the steering wheel,” explains Gustav Neander, project manager for Volvo Dynamic Steering. He adds:
“At low speeds the electric motor’s assistance makes the truck exceptionally easy to steer. Even a heavily loaded construction truck operating off-road on a rough surface can be steered without the slightest effort. Truck drivers who’ve tested the system during the development process have all been highly impressed.”
Superior in all operating conditions
The system’s benefits can be summarised in four points:
Steering is elevated to a new dimension
Volvo Dynamic Steering addresses the most frequent occupational injuries suffered by heavy goods vehicle drivers. Official figures from the Swedish Work Environment Authority reveal that truck drivers are over-represented in occupational injury statistics.
“Almost four out of ten truck drivers complain every week of pain in the back, neck, shoulders or arms. Our improved steering system offers a more relaxed driving experience that should counteract this kind of problem in the working environment,” relates Gustav Neander. He adds:
“Volvo Dynamic Steering elevates the steering of heavy vehicles to an entirely new dimension. The technology makes the driver’s working conditions more relaxed and controlled.”
