The invention relates to a control system and method for a steering apparatus for rear wheels of a vehicle. The system includes: a first magnet mounted to a steering application mechanism; a second magnet mounted to the motor rotor; the first magnetic sensor is used for detecting the first magnetic field intensity of the first magnet and the change speed of the first magnetic field intensity to generate a first detection value of linear displacement; a second magnetic sensor detecting a second magnetic field intensity of the second magnet and a change speed thereof to generate a detection value of the rotational displacement; and a control unit, and a controller that acquires a first detection value of the linear displacement from the first magnetic sensor, acquires a detection value of the rotational displacement from the second magnetic sensor, and determines a second detection value of the linear displacement on the basis of the detection value of the rotational displacement. An output value of the linear displacement is determined for representing a steering angle of a rear wheel of the vehicle based on the first and second detected values of the linear displacement, and a power-on state of the motor rotor is controlled based on an offset distance of the output value of the linear displacement from a reference zero. The system and the method are accurate and safe.
