Danfoss Power Solutions announces the release of its PVED-CLS actuator option for the OSPE steering unit, the industry’s first intelligent steering option with full safety integration.

  • Incorporates both a steering and a safety controller into an electrohydraulic actuator, saving development resources and accelerating time to market for OEMs
  • Connects directly with GPS to allow automatic steering for a wide array of off-highway machinery for increased productivity
  • Improves driver comfort with “Quick Steering” functionality, and enables joystick or mini wheel steering for all applications
  • Certified to meet new global safety standards
  • Eliminates need for an external controller to monitor electrohydraulic section of steering valve
  • Software-based system
  • Comes pre-configured with numerous steering-specific safety functions informed by comprehensive safety analysis and customer research
  • Can be adjusted to meet specific output and safety requirements of each application
  • SASA sensor detects absolute position and speed of steering wheel to provide variable ratio (Quick Steering) performance to actual off-highway conditions
  • Offers integrated electrical follow-up (EFU) which aligns steering wheel with tires to ensure precise, unwavering drive trajectories
  • Direct contact with system pressure and feedback from the LVDT transducer, operator is able to react more quickly and accurately than with an external controller
  • Tight sensor coupling also means less machine downtime and fewer false alarms
  • In case of a fault, monitor gives operators manual control within the electrohydraulic safe state
  • Integration of safety controller into steering unit significantly reduces system complexity
  • Easily integrates with other Danfoss components and electronics for full machine control
  • Certified by TÜV SÜD, the German safety validation organization, for functional safety of electronic equipment (SIL2 for IEC 61508) and functional safety of control systems (PL d, ISO 13849 and AgPL d for ISO 25119 [EN 16590])
  • Hardware is based on fully redundant Category 3 system architecture which takes care of steering hazards off-road
  • Includes “E-mark” stamp from VCA (the United Kingdom Vehicle Approval Authority), the general certification regarding EMC (directive ECE R10) which OEMs can use toward final vehicle homologation
