EPAS - How it works

  • The EPAS system goes inline with the existing steering column.
  • An electric motor and torque sensor are fitted in-line with the steering column.
  • The torque sensor monitors the amount of force applied by the driver.
  • This signal is fed into the EPAS ECU where the motor delivers the appropriate amount of assistance to power the steering rack/box.



  • No hydraulics required.
  • Lighter than a comparable hydraulic system.
  • No hydraulic pump dragging on the engine.
  • Weight of steering adjustable.
  • Data available over CAN bus (certain systems only).
  • Can be retro fitted to existing steering system.
