Both Volvo FMs must maintain the exact same speed and distance while driving in reverse – a feat only made possible by Volvo Dynamic Steering.

Volvo Dynamic Steering – the facts

Volvo Dynamic Steering is based on a conventional mechanical steering system where a steering shaft links up to a steering gear. A hydraulic servo unit generates force that helps the driver turn the truck’s road wheels.

In Volvo’s system an electronically controlled electric motor is added, which is attached to the steering shaft. This electric motor works together with the hydraulic power steering and is adjusted thousands of times per second by the electronic control unit.

At low speeds, the electric motor adds extra force and at higher speeds, the electric motor automatically regulates the steering and compensates for irregularities that feed through to the steering wheel, caused for instance by side winds or bumps in the road surface.
