The Volvo Trucks Volvo Dynamic Steering (VDS) is an active steering system designed to lessen steering force up to 85 percent, helping reduce driver fatigue and increase road safety, says the company. The steering system features an electric motor mounted on top of the hydraulic steering gear. Input from multiple vehicle sensors, at over 2,000 times per second, determine the appropriate steering wheel response. VDS is ideal for diverse and changing terrains and automatically adjusts to handle any roadway condition. With more controlled steering, VDS helps reduce operational fatigue by filtering road vibration and noise through the steering wheel.
