The Servotwin® electro-hydraulic steering system for heavy commercial vehicles is the innovative combination of the RB-Servocom® ball nut power steering system with an electronic drive and control unit. The system offers speed-dependent steering assistance with active reverse, various driver assistance functions and enables automated driving functions. The superimposed electric circuit also replaces the second hydraulic circuit previously required for commercial vehicles with two steered axles.
