The embodiments of the present invention are described in detail below with reference to the drawings.

Referring to FIG. 2, an architectural block diagram of an embodiment of a data feedback device of the present invention is shown, which is combined with a partial structural schematic of a vehicle luminaire, that is, a portion of an actuator. Please refer to FIG. 3 for a schematic diagram of the operation of the embodiment of the data feedback device of the present invention.

As shown in Figures 2 and 3, the actuator 10' includes a drive motor 14, a gear set 13 and an output shaft 11. The output shaft 11 is pivotally connected to the socket of the vehicle lamp, and the lamp holder is pivoted when the output shaft 11 is rotated. The light from the luminaire will be deflected by the lamp holder to deflect the light.

The serrated piece 12 has serrations at one end and the other end is sleeved to the output shaft 11. The gear set 13 is disposed between the band saw blade 12 and the drive motor 14, and is toothed to the band saw blade 12 and the drive motor 14. When the driving motor 14 is operated and stopped, the rotation and stationary of the gear set 13 are driven. Gear set 13 will The operation of the band saw blade 12 and the stationary state are driven to drive the operation and stop of the output shaft 11.

The data feedback unit 20 includes a plurality of magnetic units 21 and a feedback 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. The setting of the feedback circuit 22 is not limited. In this case, it is preferable that the outer sleeve is sleeved outside the output shaft 11, and the outer shape does not interfere with the gear set 13, the drive 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 on the magnetic unit 21, a displacement value corresponding to the output shaft 11 is generated. The feedback module 24 provides this displacement value to the vehicle controller 30. When the vehicle controller 30 obtains the displacement value, the drive setting of the drive motor 14 is regulated. The adjusting the driving setting of the driving motor 14 by the vehicle controller 30 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 14.

Additionally, the method by which the feedback module 24 returns the displacement value to the vehicle controller 30 includes at least the following:

(1) The feedback module 24 stores a displacement comparison table. The displacement comparison table records the displacement control values of the plurality of output shafts 11, and each of the displacement control values has a corresponding sensing value. When the feedback module 24 obtains the sensing result of the magnetic unit 21 on the magnetic unit 21, the sensing result and all the sensing values are compared, and the displacement value corresponding to the sensing value is taken out from all the displacement comparison values, and the displacement value is provided. Vehicle controller 30. The vehicle controller 30 will regulate the drive setting of the drive motor 14 based on this displacement value. That is to say, the vehicle controller adjusts the relevant parameters such as the driving voltage, the driving current, the rotating speed, the turning time, and the number of revolutions of the driving motor 14 with reference to the obtained displacement value.

(2) At the point (1), when the feedback circuit 22 determines the induction When the result cannot match the sensing values, the similar sensing value close to the sensing result is taken as the selected value, and the displacement comparison value corresponding to the similar sensing value is provided as the displacement value to provide the displacement value to the vehicle controller 30.

(3) The feedback circuit 22 further includes an operational power detection module 25. The operational power detection module 25 is configured to detect power between the feedback circuit 22 and the vehicle controller 30 (ie, the potential difference between the feedback circuit 22 and the vehicle controller 30), and calculate the power between the power and a standard operating power. The power difference value, and then a displacement compensation parameter is calculated. 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 vehicle controller 30 then adjusts the drive setting to the drive motor 14 based on the acquired displacement compensation parameters and displacement values. 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 14.

(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 will adjust the drive settings for the drive motor 14 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 illustrated in FIG. 2 and FIG. 3, and the method includes the following steps:

As previously mentioned, 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. The magnetic sensitive unit 23 is disposed on the feedback circuit 22 and adjacent to the position of the magnetic unit 21 for sensing The magnetic force emitted by the magnetic unit 21.

In step S120, the sensing result of the magnetic unit 21 by the magnetic sensing unit 23 is obtained by a feedback circuit 22, and a displacement value corresponding to the output shaft 11 is generated and supplied to the vehicle controller 30. The vehicle controller 30 will adjust the drive setting of the drive motor 14 in accordance with this displacement value.

As described above, the feedback module 24 is coupled to the vehicle controller 30 (BCM) and the magnetic sensitive unit 23. The regulation of the drive of the drive motor 14 by the vehicle controller 30 includes adjusting at least one of a drive voltage, a drive current, a rotational speed, a rotation time, and a number of revolutions of the drive motor 14.

FIG. 5 and FIG. 6 are schematic diagrams showing details of an embodiment of a data feedback method according to the present invention. In step S120, the manner in which the feedback module 24 returns the displacement value to the vehicle controller 30 further includes the following:

(A) Step S121, the feedback result is compared by the feedback circuit 22 to a displacement comparison table to extract the displacement value corresponding to the sensing result from the plurality of displacement control values.

In step S122, the displacement value is supplied from the feedback circuit 22 to the vehicle controller. The vehicle controller 30 regulates the drive setting of the drive motor 14 based on the obtained displacement value.

(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 14, and the vehicle controller 30 controls the standard power value of the drive motor 14 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 14 based on the displacement compensation parameters and the displacement values.
