Assisted Operation

In addition to manual steering operation, steering sensor on piston shaft transmits to control unit when it receives a steering input. The control unit calculates an adequate motor control with addition of speed signals two speed sensors, then transmits a control signal to power unit. Based on signal from control unit, power unit drives motor inside gearbox. The torque generated by motor is transmitted to ball screw through gears and converted into an assisting thrust in axial direction of rack. The assisting thrust acts in steering direction and lessens steering force required at steering wheel.
