Basic Principles

When steering,ECU will monitor the signals of the engine’s rotation speed and vehicle speed transmitted through torque sensor and CAN line and after computing process,give action instructions to the controller of electric motor so that the motor can output the corresponding driving torque according to the specific needs.CX70 EPS circuit diagram is shown in Fig.5.2 and the position of the fuse is shown in Fig.5.3.
