“On the road” around the world

With the experience of thousands of systems “on the road” around the world, the Space Drive system now represents a true revolution in drive-by-wire technology. This safe and reliable high-performance system offers the perfect combination of fully developed and sophisticated hardware and functional and individually applicable software. What’s more, an extremely wide range of interfaces (CAN, LIN, FlexRay) makes Space Drive multi-compatible. Made by Schaeffler Paravan!

Key system facts

The highlights of the Schaeffler Paravan drive-by-wire system
  • Active redundancy: Motors with multiple safety features and full power, even if a control circuit fails
  • Error memory in several components (recording of relevant events)
  • Sufficient pedal distance and force in all vehicles, even if the vehicle’s own control circuit fails
  • Permanent scanning of the status of components
  • Speed-dependent steering enables driving with a natural steering sensation at high speeds.
  • Better braking at low speeds, thanks to automatic adjustment of pedal distance and force
  • Different throttle curves are available
  • Parameters may be set (adjusted) via PC and touch panel to suit each customer and their needs (in online mode)
  • One-click support via our innovative diagnostic tool with a completely new design
  • Integrated interface
  • Optimal and flexible design to fit all vehicles
  • Can be switched to several languages – operation and error description via comprehensible fair copy without any encoding
  • Parameters cannot be altered without authorization
  • Innovative modular system of operating elements for better customization
  • Higher-quality ergonomics, operability, flexibility, and durability
  • No unpleasantly cold components that could lead to cramps
  • Made in Germany = fast spare parts deliveries
  • Space Drive technology complies with all relevant standards and regulations in Europe
  • Thousands of systems on the road worldwide since 2003
