EPAS500 MGU with Autonomous Control

A versatile solution for both manned and unmanned operations, where the extra power of the Ultra system isn’t required.

  • Ideal for small, 12V DC vehicles with no existing PAS system.
  • 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 90Nm / 66 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.
