The New Volvo FMX is So Easy to Steer
The film “The Hamster Stunt” has been a major success on Youtube and has been viewed more than 3.4 million times in just one week. It shows how the new Volvo FMX, equipped with Volvo Dynamic Steering, is steered by a hamster on rough, twisting tracks in a quarry.
Volvo Dynamic Steering is a new system from Volvo Trucks that allows the driver to steer a heavily laden truck without effort. At low speeds, an electric motor replaces the driver's muscle power. The system's developers aimed to deliver perfect steering feel in all operating conditions.
“At low speeds, a heavily laden vehicle is so easy to manoeuvre that it can be steered with just one finger. When driving on the highway, this dynamic steering system offers unbeatable directional stability, explains Jan-Inge Svensson, the engineer behind the development of the system’s software at Volvo Trucks.
Electric Motor Takes the Load Off the Driver
“There are sensors in a number of different locations and together they provide a comprehensive picture of what is happening to the truck. For instance, sensors on the wheels and the transmission’s output shaft measure the vehicle’s road speed, while another sensor identifies which gear is currently engaged,” relates Sten Ragnhult, who was responsible for developing the system’s hardware at Volvo Trucks.
In the film “The Hamster Stunt” the system’s properties are put to the test by allowing a 175 gram hamster steer the truck. The test was carried out in a quarry in the Spanish city of Ourense. A specially designed hamster treadmill was attached to the steering wheel. An experienced stunt driver handled the accelerator and brakes and got the hamster to steer in the right direction by tempting him with a carrot. The film shows how the big truck gently and safely makes its way up a twisting, narrow hilly track in the quarry.
“I can assure you that this is for real – the hamster really can steer the truck,” says Sten Ragnhult, who together with his colleague Jan-Inge Svensson was on site in Spain during the test.
