Volvo Trucks technology help drivers steer clear 20 February 2013

Volvo Trucks has announced what it is calling Volvo Dynamic Steering – a combination of conventional hydraulic power-steering with an electronically-controlled electric motor fitted to the steering gear.

The result, says the manufacturer, is precise steering that gives the truck driver a safer and more comfortable working environment.

The electric motor delivers a maximum torque of 25Nm and is speed regulated thousands of times per second by its control unit.

"The task of the electric motor is to deliver a perfect steering feel for every single moment of operation," states Gustav Neander, project manager for Volvo Dynamic Steering.

"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," he explains.

At low speeds, the electric motor's assistance makes the truck exceptionally easy to steer," continues Neander.

"Even a heavily-loaded construction truck, operating off-road and on a rough surface, can be steered without the slightest effort. Truck drivers who've tested the system during its development have all been impressed."
