DPS stands for Digital Power Steering.  It is a technology developed by the Ognibene Power company, from Reggio Emilia, to integrate the traditional driving device of off-highway vehicles with the most advanced automatic and GPS driving devices, without having to equip the machine with additional systems. «The DPS – explains with a technical note the company from Reggio Emilia – is a “brushless” engine coaxially applied in the steering column, between the steering wheel and the steering, and is equipped with sensors that measure both the angle and the torque applied by the operator ». These data are then used by the DPS ECU control unit of the system to process the optimal steering response and its haptic feedback, based also on the tractor speed and the position of the front wheels.  “The DPS technology – continues the manufacturer – introduces new, intelligent features, improving safety, control, stability and driving precision even at high speeds.  Both off-road and on the road “.  Thanks to the low-power engine design, placed in a coaxial position relative to the steering shaft, the DPS system can be integrated into the steering column. And this makes it a lot easier the assembly, especially if compared with an electro-hydraulic device. The DPS ECU connects to the vehicle through the CAN BUS and, thanks to the brushless solution, is characterized by zero maintenance. The system modularity allows obtaining a complete range of smart pillars, always integrating the same DPS module. «The DPS technology – concludes Ognibene Power – reduces the operator muscular load and repetitive efforts obtaining a smoother and easier driving style, especially in demanding operations». With the introduction of a new intelligent steering system, it is now possible to have new features such as haptic warnings (for example the steering wheel can be put in vibrating mode to indicate a specific vehicle status) and there can be customizable feedbacks on the steering wheel. The system modularity and flexibility make it possible for OEM to adapt the vehicle to the needs of the end user.
