Volvo Trucks – Demonstration of the unique technology Volvo Dynamic Steering


The VDS system was something
that was in the air. People at the passenger car side
have started to work on active steering- -and we thought:
“Why not do it for trucks?” It would even be more beneficial
for trucks than for passenger cars. There are three features of VDS
that are beneficial for the driver. The first one is the low steering wheel
force required at low speed. The second one
is the disturbance reaction. And the third one is the steering wheel
returnability when reversing. On a regular truck
without Volvo Dynamic Steering- -I have to work much more when I’m
maneuvering the truck at low speed. Volvo Dynamic Steering
takes away a lot of the work- -that the driver normally has to do. The steering wheel force required
to maneuver a truck at low speed- -is a lot less
with Volvo Dynamic Steering. It’s about 20%
if I compare with a regular truck. Also, when I reverse it requires
very little effort to steer the vehicle. I can let the steering wheel
slide back in my hands. If the driver is relaxed when he’s
reversing, he will make fewer mistakes- -and it will reduce
the risk of accidents. Imagine that we are
in a timber truck in the forest. Since the road is uneven,
it’s beneficial- -to have the disturbance reaction. Volvo Dynamic Steering will keep
the front wheels straight- -if the driver doesn’t apply
any torque to the steering wheel. The software is controlling the electric
motor about 2,000 times per second. So, it’s very responsive
to external disturbances. It’s quite an amazing figure. It’s much faster than most systems
in the truck world.
