  • Page 528: General Description

    6C-2 Power Assisted Steering System: General Description P/S System Description B931H26301001 This electronic power steering (EPS) system consists of a EPS control unit (2), a torque sensor (3), a EPS motor (4). In this system, the EPS control unit determines the level and direction of the assist force for the handlebars (1) according to the signal from the torque sensor and the vehicle speed signal from speed sensor (9).
  • Page 529 Power Assisted Steering System: 6C-3 Detecting Principle The column shaft is connected to the input shaft by means of serration. The output shaft and input shaft are connected via torsion bar. When torque is inputted from the column shaft, a relative angular displacement occurs between the input shaft and the output shaft due to twist of the torsion bar.
  • Page 530 6C-4 Power Assisted Steering System: Control System In the EPS control unit, the steering assist control determines the basic power assist force and the convergence control improves the steering operation feeling. The controller determines the target motor current by the calculation of these controls and the maximum current limiting control and it also regulates the motor current so that the target motor current and the actual current are matched.
