Microsteer MGU with Autonomous Control

Our most compact system, for applications that do not require as much assistance as the Ultra or EPAS500 MGU options. Ideal for use as a steering servo when mated to a hydraulic power steering system.

  • Used on vehicles that still utilize hydraulic power steering and require autonomous & manned control.
  • Ideal for 12V DC, very low steering input load vehicles.
  • MGU is fitted anywhere inline between the steering wheel and rack input pinion.
  • Input shaft allows manual control as well as autonomous control.
  • System can provide up to 37Nm / 26.5 ft.lb of steering column torque
  • CAN Bus control using one of the three following options:
    • Sending a simulated torque sensor signal.
    • Sending a +/- duty cycle demand for direct control of the EPAS motor.
    • Sending heading and gain request for the EPAS motor to steer to.
