Circuit 22. The magnetic unit 21 can be a magnet or an electromagnet and is provided with a position where the serrated piece 12 abuts to the feedback circuit 22.

In this case, it is preferable that the outer casing of the drive motor 11 is sleeved and the outer shape does not interfere with the gear set 13, the stepping motor 14, or other unpresented components. The feedback circuit 22 includes more than one magnetic sensing unit 23 and a feedback module 24. The magnetic sensitive unit 23 is disposed adjacent to the magnetic unit 21, and senses a position at which the magnetic unit 21 emits magnetism. The sensing unit may be the magnetic sensing unit 23 as a Hall element or a magnetic induction switch. The feedback module 24 is connected to the vehicle controller 30 (BCM) and the magnetic sensitive unit 23.

When the feedback module 24 obtains the sensing result of the magnetic unit 21 by the magnetic sensitive unit 23, a displacement value corresponding to the driving motor 11 is generated. The feedback module 24 provides this displacement value to the vehicle controller 30. When the vehicle controller 30 acquires the displacement value, the drive setting of the drive motor 11 is regulated. The vehicle controller 30 regulating the driving setting of the driving motor 11 includes adjusting at least one of a driving voltage, a driving current, a rotating speed, a rotating time, and a number of rotating turns of the driving motor 11.

The value is used as the displacement value to provide this displacement value to the vehicle controller 30.

(3) The feedback circuit 22 further includes an operational power detection module 25. The operation power detecting module 25 is configured to detect power between the feedback circuit 22 and the vehicle controller 30, and calculate a power difference value between the power and a standard working power, thereby calculating a displacement compensation parameter. Here, electric power refers to "the function of electricity generated by electricity, usually referred to as power for power". The presentation of power includes various numerical representations such as voltage, current, power, and signal level change. The power difference value refers to a difference value of various variations in performance of electric energy such as the above-mentioned voltage, current, power, and the like. This displacement compensation parameter is provided to the vehicle controller 30 by the operational power detection module 25. Alternatively, the displacement compensation parameter is obtained by the feedback module 24 and then provided to the vehicle controller 30. That is, the feedback circuit 22 provides displacement values and displacement compensation parameters to the vehicle controller 30.

The displacement compensation parameter includes adjusting at least one of a driving voltage, a driving current, a rotation speed, a rotation time, and a number of rotations of the drive motor 11.

(4) According to the third point, when the feedback circuit 22 determines that the sensing result of the magnetic unit 21 on the magnetic unit 21 is that no induction is obtained, the feedback module 24 directly provides the displacement compensation parameter to the vehicle controller 30. The vehicle controller 30 adjusts the drive setting of the drive motor 11 directly in accordance with the displacement compensation parameters.

4 is a schematic flow chart of an embodiment of a data feedback method of the present invention. The data feedback method is applicable to the data feedback device 20 shown in FIG. 2 and FIG. 3, and the method includes the following steps: Step S110, using a magnetic sensing unit 23 to sense a plurality of magnetic units 21 spaced apart from the edge of the sawtooth blade 12 Magnetic changes.

(B) Step S126, a power compensation module 25 detects the power difference between the feedback circuit 22 and the vehicle controller 30 and a standard operating power, and calculates a displacement compensation parameter. The installation of the cover data feedback device 20 and the vehicle luminaire are not the original luminaire specifications, which inevitably affects the power balance between the vehicle luminaire and the vehicle circuit. Therefore, the power controller module 25 is required to detect the power between the vehicle controller 30 and the drive motor 11, and the vehicle controller 30 controls the standard power value of the drive motor 11 before determining the power and the unloaded data feedback device. The power difference value is used to calculate a displacement compensation parameter.

In step S127, the displacement compensation parameter and the displacement value are supplied from the feedback circuit 22 to the vehicle controller 30. The vehicle controller 30 regulates the drive setting of the drive motor 11 in accordance with the displacement compensation parameter and the displacement value.
