[0076] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of the first embodiment of the AGS grille angle display circuit of the present invention.

[0077] like Figure 1 As shown, the AGS grid angle display circuit of this embodiment includes: a main control module 100, an AGS grid motor module 200, and a display module 300.

[0078] The main control module 100 is connected to the AGS grid motor module 200 and the display module 300, respectively.

[0079] The main control module 100 is used to output an automatic calibration signal to the AGS grid motor module 200 when powered on.

[0080] It should be noted that the automatic calibration signal can be the signal that enables the AGS grid motor module 200 to perform automatic calibration.

[0081] In a specific implementation, during the power-on process, the main control module 100 can output the aforementioned automatic calibration signal to the AGS grid motor module 200 to communicate with the AGS grid motor module 200.

[0082] The AGS grid motor module 200 is used to perform calibration based on the automatic calibration signal, and when the calibration is successful, it outputs a calibration success signal to the main control module 100 based on the opening and closing angle of the AGS grid.

[0083] In a specific implementation, when the AGS grid motor module 200 receives the aforementioned automatic calibration signal, AutoCalibReq is set to 1 to perform automatic calibration. Upon successful calibration, it automatically rotates one revolution and outputs the signal of the AGS grid motor opening and closing angle movement and the calibration success signal together as a calibration success signal to the aforementioned main control module 100 for communication with the aforementioned main control module 100.

[0084] It should be understood that when the main control module 100 is successfully calibrated, it can control the indicator light to flash to indicate that communication with the AGS grid motor module 200 is successful, thereby improving the user experience.

[0085] The main control module 100 is also used to output an angle display signal corresponding to the opening and closing angle to the display module 300 based on the calibration success signal.

[0086] It should be noted that the angle display signal can be the signal used to trigger the LCD digital tube to display the angle.

[0087] In a specific implementation, when the main control module 100 receives the calibration success signal, it can read the opening and closing angle movement signal in the calibration success signal and output an angle display signal to the display module 300 based on the opening and closing angle movement signal.

[0088] The display module 300 is used to display the opening and closing angle based on the angle display signal.

[0089] In a specific implementation, the display module 300 can use the aforementioned angle display signal to drive the LCD driver chip to drive the LCD digital tube to display the opening and closing angle of the AGS grille in real time, thereby realizing real-time display and monitoring of the opening and closing angle of the AGS grille.

[0090] It should be understood that the aforementioned LCD driver chip can be a chip that drives the LCD digital tube for display, such as the TM1652 chip.

[0091] In this embodiment, the main control module outputs an automatic calibration signal to the AGS grille motor module upon power-up. The AGS grille motor module performs calibration based on the automatic calibration signal, and upon successful calibration, outputs a calibration success signal to the main control module based on the opening / closing angle of the AGS grille. The main control module outputs an angle display signal corresponding to the opening / closing angle to the display module based on the calibration success signal. The display module displays the opening / closing angle based on the angle display signal. Because this embodiment outputs an angle display signal based on the calibration success signal corresponding to the opening / closing angle of the AGS grille, and then displays the opening / closing angle based on this angle display signal, compared to the existing technology that uses a motor LIN communication matrix to perform quality detection on the AGS grille motor, the circuit in this embodiment is simple to operate and achieves effective monitoring of the AGS grille opening / closing angle.

[0092] refer to Figure 2 , Figure 2 This is a schematic diagram of the second embodiment of the AGS grille angle display circuit of the present invention.

[0093] Based on the first embodiment described above, in this embodiment, the AGS grille angle display circuit further includes a mode switching module 400, wherein the mode switching module 400 is connected to the main control module 100.

[0094] The mode switching module 400 is used to connect the circuit with the main control module when it receives the target mode trigger signal, and output a preset high-level signal to the main control module 100.

[0095] It should be noted that the target mode trigger signal can be a signal used to trigger the corresponding mode. For example, if each mode has a corresponding switch control, pressing the switch will trigger the mode corresponding to that switch. Similarly, if each mode has a corresponding knob control, rotating the knob to the target value will trigger the mode corresponding to that target value. This embodiment does not impose any restrictions on this.

[0096] Understandably, the target mode can be a cyclic mode that controls the AGS grille to move cyclically between any angles, or a holding mode that controls the AGS grille to maintain any angle. The opening and closing angle of the AGS grille can be controlled to be the opening and closing angle of each mode by triggering signals of different modes.

[0097] It should be noted that the preset high-level signal can be a trigger signal used to make the main control module 100 output an angle control signal. The preset high-level signal can be the level signal corresponding to the internal working voltage of the chip when it is working, or it can be a level signal input from outside the chip.

[0098] In a specific implementation, when the above-mentioned mode switching module 400 receives the above-mentioned target mode trigger signal, it can connect the circuit corresponding to the corresponding mode between itself and the above-mentioned main control module 100, so that the preset high-level signal of the trigger angle control signal is output to the above-mentioned main control module 100.

[0099] The main control module 100 is used to output an angle control signal corresponding to the target mode to the AGS grid motor module 200 according to the received preset high-level signal when the circuit is turned on.

[0100] It should be noted that the angle control signal can be a control signal that controls the opening and closing angle of the AGS grille.

[0101] In a specific implementation, when the circuit corresponding to the target mode is turned on, the main control module 100 triggers the angle control signal corresponding to the target mode according to the received preset high-level signal, and outputs the angle control signal to the AGS grid motor module 200. For example, if the target mode is a cycle mode, the angle control signal corresponding to the cycle mode can be output to control the AGS grid to cycle between any angle.

[0102] The AGS grid motor module 200 is used to adjust the opening and closing angle of the AGS grid through the angle control signal.

[0103] In a specific implementation, the AGS grid motor module 200 can adjust the opening and closing angle of the AGS grid to the angle corresponding to the target mode through the aforementioned angle control signal. For example, if the target mode is a cycle mode, the opening and closing angle of the AGS grid can be adjusted to several angles corresponding to the cycle mode through the aforementioned angle control signal, and the grid cycles between several angles.

[0104] It should be understood that this embodiment achieves intelligent control of the AGS grille by outputting an angle control signal corresponding to the target mode according to the received target mode trigger signal, and adjusting the opening and closing angle of the AGS grille according to the angle control signal, thereby improving the user experience.

[0105] Furthermore, in order to display the changes in the opening and closing angle of the AGS grille and improve the flexibility of AGS grille monitoring, in this embodiment, the AGS grille motor module 200 is also used to output an angle change signal corresponding to the change in the opening and closing angle to the main control module 100.

[0106] It should be noted that the angle change signal can be the signal corresponding to the change in the opening and closing angle of the AGS grille.

[0107] In a specific implementation, after adjusting the opening and closing angle based on the aforementioned angle control signal, the AGS grid motor module 200 can trigger a corresponding angle change signal based on the change in the opening and closing angle, such as a cycle from 0° closed to 90° fully open, and output the angle change signal to the aforementioned main control module 100 through the serial communication pin LIN.

[0108] The main control module 100 is also used to output an angle change display signal to the display module 300 based on the angle change signal.

[0109] It should be noted that the angle display signal can be a signal used to display the opening and closing angle of the AGS grille.

[0110] In a specific implementation, the main control module 100 can receive the aforementioned angle change display signal based on its internal main control chip, trigger the aforementioned angle display signal based on the angle change display signal, and output the angle display signal to the display module 300.

[0111] The display module 300 is also used to display the change in the opening and closing angle based on the angle change display signal.

[0112] In a specific implementation, the display module 300 can be driven by an LCD digital tube driver chip to display the changing opening and closing angle value based on the aforementioned angle display signal. For example, when the AGS grille changes from 0° to 90°, the entire process of changing from 0° to 90° can be displayed in real time. Correspondingly, when the AGS grille changes from 90° to the closed mode of 0°, the entire process of changing from 90° to 0° can also be displayed in real time, realizing real-time monitoring of the opening and closing angle changes and improving the user experience.

[0113] refer to Figure 3 , Figure 3 This is a schematic diagram of the third embodiment of the AGS grille angle display circuit of the present invention.

[0114] Based on the second embodiment described above, in this embodiment, the AGS grille angle display circuit further includes a communication module 500, wherein the communication module 500 is connected to the main control module 100 and the AGS grille motor module 200 respectively.

[0115] The main control module 100 is also used to output an angle trigger signal corresponding to the target mode to the communication module 500 according to the received preset high-level signal when the circuit is turned on.

[0116] Understandably, the angle trigger signal can be the trigger signal that triggers the angle control signal in the communication module 500.

[0117] In a specific implementation, the main control module 100 can output angle trigger signals corresponding to each mode to the communication module 500 according to the above-mentioned circuit based on different modes. Since the angle trigger signals can be accurately output to the communication module 500, the accuracy of the subsequent angle control signals output to the AGS grid motor module 200 can be improved.

[0118] The communication module 500 is used to output an angle control signal to the AGS grid motor module 200 based on the angle trigger signal.

[0119] In a specific implementation, the communication module 500 can be connected to the AGS grid motor module 200 via a LIN bus, thereby accurately transmitting the angle control signal triggered by the angle trigger signal to the AGS grid motor module 200, which improves the accuracy of the AGS grid opening and closing angle control.

[0120] Furthermore, in order to improve the accuracy of AGS grille opening and closing angle control, in this embodiment, the mode switching module 400 is also used to conduct a preset cyclic mode loop with the main control module and output a preset high-level signal to the main control module 100 when the target mode trigger signal is a cyclic mode trigger signal.

[0121] It should be noted that the preset cycle mode loop can be used to control the AGS grille opening and closing angle to cycle between set angles.

[0122] Understandably, the aforementioned preset high-level signal can be the internal operating voltage of the chip inside the main control module 100 when it is working normally, such as 3.3V.

[0123] The main control module 100 is also used to output a cycle angle trigger signal corresponding to the target mode to the communication module 500 according to the received preset high-level signal when the preset cycle mode circuit is turned on.

[0124] It should be noted that the cycle angle trigger signal can be the trigger signal corresponding to the cycle angle in the cycle mode. The cycle angle can be one of several opening and closing angles set in the cycle mode, such as 30°, 45° and 90°.

[0125] In a specific implementation, the main control module 100 can also flash the corresponding indicator light when it detects that the above-mentioned cyclic mode loop is connected, or when it detects that the above-mentioned target mode trigger signal is a cyclic mode trigger signal, so as to indicate that the user's cyclic mode has been successfully triggered, further improving the user's experience.

[0126] The communication module 500 is used to output a cyclic angle control signal to the AGS grid motor module 200 based on the cyclic angle trigger signal.

[0127] It should be noted that the cycle angle control signal can be a control signal used to control the AGS grille to cycle between cycle angles, and this cycle angle control signal can be triggered by the aforementioned cycle angle trigger signal.

[0128] In a specific implementation, the communication module 500 can receive the cyclic angle trigger signal output by the main control module 100 through its internal transceiver chip, and the transceiver chip can trigger the cyclic angle control signal based on the cyclic angle trigger signal, and output the cyclic angle control signal to the AGS grid motor module 200 through the serial communication pin LIN of the transceiver chip.

[0129] The AGS grid motor module 200 is also used to adjust the opening and closing angle of the AGS grid motor to a cyclic motion between several preset angles through the cyclic angle control signal.

[0130] In a specific implementation, the AGS grid motor module 200 can receive the cyclic angle control signal output by the communication module 500 through the serial communication pin LIN, and adjust the opening and closing angle of the AGS grid to cycle between the aforementioned cyclic angles through the cyclic angle control signal. For example, it can control the opening and closing angle to move back and forth between 0° and 90°, thereby making the AGS grid in a cyclic mode and achieving precise cyclic control of the opening and closing angle of the AGS grid.

[0131] In this embodiment, the display module 300 is also used to display the number of cycles of the opening and closing angle cyclic motion based on the angle display signal.

[0132] In its implementation, the display module 300 can display the number of cycles in which the opening and closing angle of the AGS grille changes from a set starting angle to a set ending angle, such as from 0° to 90°. This allows for the display of the number of cycles, facilitating the testing and monitoring of the AGS grille and improving the user experience.

[0133] In this embodiment, the mode switching module 400 is further configured to, when receiving a target mode trigger signal as a hold mode trigger signal, conduct a preset hold mode circuit with the main control module 100 and output a preset high-level signal to the main control module 100.

[0134] It should be noted that the preset holding mode circuit can be a circuit used to maintain the set opening and closing angle of the AGS grille by output control.

[0135] The main control module 100 is also used to output a preset holding angle trigger signal corresponding to the target mode to the communication module 500 according to the received preset high-level signal when the preset holding mode circuit is turned on.

[0136] It should be noted that the preset holding angle trigger signal can be the trigger signal corresponding to the angle set in the holding mode, such as 30°, 45° and 90°.

[0137] In a specific implementation, the main control module 100 can also flash the corresponding indicator light when it detects the above-mentioned preset hold mode circuit or when it detects that the above-mentioned target mode trigger signal is a hold mode trigger signal, so as to indicate to the user that the hold mode has been successfully triggered, further improving the user experience.

[0138] The communication module 500 is used to output a preset holding angle control signal to the AGS grid motor module 200 based on the preset holding angle trigger signal.

[0139] It should be noted that the preset holding angle control signal can be a control signal used to control the AGS grille to maintain the preset holding angle, and the preset holding angle control signal can be triggered by the preset holding angle trigger signal.

[0140] In a specific implementation, the communication module 500 can receive the preset holding angle trigger signal output by the main control module 100 through the transceiver chip, and the transceiver chip can trigger the preset holding angle control signal based on the preset holding angle trigger signal, and output the preset holding angle control signal to the AGS grid motor module 200 through the serial communication pin LIN of the transceiver chip.

[0141] The AGS grid motor module 200 is also used to maintain the opening and closing angle of the AGS grid motor at a preset holding angle through the preset holding angle control signal.

[0142] In a specific implementation, the AGS grid motor module 200 can receive the preset holding angle control signal output by the communication module 500 through the serial communication pin LIN, and use the preset holding angle control signal to maintain the opening and closing angle of the AGS grid at the preset holding angle, such as 30°, 45° and 90°, so that the AGS grid is in holding mode, and the accuracy of maintaining any angle of the opening and closing angle of the AGS grid is achieved.

In the figure, the main control module 100 includes: a main control chip U1, a first resistor R1, a second resistor R2, a first to a third capacitor C1 to C3, and a first crystal oscillator Y1. The mode switching module 400 includes: a cycle mode switch K1 and a hold mode switch K2.

[0144] The main control chip U1 has the following configuration: its positive voltage pin VDD is connected to the first power supply VCC1; its negative voltage pin VSS is grounded to GND; its battery operating mode pin VBAT is connected to the first end of the first resistor R1; the second end of the first resistor R1 is connected to both the first power supply VCC1 and the first end of the first capacitor C1; the second end of the first capacitor C1 is grounded to GND; its external crystal oscillator input pin OSC_IN is connected to the first end 1 of the first crystal oscillator Y1; the second end 2 of the first crystal oscillator Y1 is grounded to GND; its external crystal oscillator output pin OSC_OUT is connected to the third end 3 of the first crystal oscillator Y1; its reference negative voltage pin Vref- is grounded to GND; and its analog positive voltage pin VDDA is connected to the first end of the second capacitor C2 and the first end of the first capacitor C1. The first terminal of capacitor C3 and the first terminal of the second resistor R2 are connected. The second terminal of the second capacitor C2 and the second terminal of the third capacitor C3 are grounded to GND. The second terminal of the second resistor R2 is connected to the first power supply VCC1. The analog working negative voltage pin VSSA of the main control chip U1 is grounded to GND. The cyclic mode pin P1 of the main control chip U1 is connected to the first terminal of the cyclic mode switch K1. The second terminal of the cyclic mode switch K1 is grounded. The hold mode pin P2 of the main control chip U1 is connected to the first terminal of the hold mode switch K2. The second terminal of the hold mode switch K2 is grounded. The first data transmission pin of the main control chip U1 is connected to the communication module 500 via USART1-TX. The second data transmission pin USART2-TX of the main control chip U1 is connected to the communication module 500. The first data reception pin USART1-RX of the main control chip U1 is connected to the communication module 500.

[0145] Understandably, the main control chip U1 can be a chip used to generate angle control signals or angle trigger signals, such as STM32F103ZET6.

[0146] It should be noted that, in order to facilitate users to precisely control the opening and closing angle of the AGS grille, the cycle mode switch can be used to control the AGS grille to cycle between different angles, such as 30°, 45°, 60°, and 90°, to further improve the user experience.

[0147] For easier understanding, please refer to Figure 5 This explanation does not limit the scope of this solution. Figure 5This is a circuit diagram of the angle switches in the cyclic mode switch in the third embodiment of the AGS grille angle display circuit of the present invention. In the diagram, the cyclic mode switch K1 can be replaced by the 30° switch K11, the 45° switch K12, the 60° switch K13, and the 90° switch K14. The first terminals of the 30° switch K11, the 45° switch, the 60° switch, and the 90° switch are all grounded. The second terminals of the 30° switch K11, the 45° switch, the 60° switch, and the 90° switch are all connected to the main control module 100 to realize the cyclic control of different opening and closing angles of the AGS grille.

[0148] In the specific implementation, switch K11 is set to a 30° switch to control the opening and closing angle of the AGS grille of the electric cover to cycle between 0° and 30°. Correspondingly, switch K12 is set to a 45° switch to control the opening and closing angle of the AGS grille to cycle between 0° and 45°. Correspondingly, switch K13 is set to a 60° switch to control the opening and closing angle of the AGS grille to cycle between 0° and 60°. Correspondingly, switch K11 is set to a 90° switch to control the opening and closing angle of the AGS grille to cycle between 0° and 90°.

[0149] It should be understood that, in addition to the aforementioned 30°, 45°, 60°, and 90° switches, switches of any other arbitrary angle can be set to achieve cyclic control of the AGS grille's opening and closing angle. Furthermore, a rotary switch can also be provided; rotating the knob triggers a switch of any angle, thus achieving angle control of the AGS grille.

[0150] It should be noted that the hold mode switch can also be set with different angle switches to keep the opening and closing angle of the electric cover at any set angle. The specific circuit diagram is as described above, and will not be repeated in this embodiment.

[0151] Understandably, when any of the mode switches, namely the cycle-on mode switch K1 and the hold mode switch K2, is closed, the closed switch can conduct the circuit between the pins of the connected chip U1, so that a preset high-level signal (such as 3.3V) is input to the main control chip U1. At this time, the main control chip U1 can output the corresponding angle trigger signal to the communication module 500 through the circuit between the closed switch and the above-mentioned closed switch. The communication module 500 can be connected to the corresponding USART1-TX, USART2-TX and USART1-RX of the main control chip U1 through its internal data receiving pin RXD and data transmitting pin TXD, thereby realizing communication and accurately receiving the angle trigger signal transmitted by the main control chip.

[0152] For easier understanding, please refer to Figure 6 This explanation does not limit the scope of this solution. Figure 6The circuit diagram of the communication module in the third embodiment of the AGS grid angle display circuit of the present invention is shown. In the figure, the communication module 500 includes: transceiver chip U2, third to seventh resistors R3 to R7, fourth capacitor C4, first diode D1 and first switch button K0.

[0153] Specifically, the data receive pin RXD of the transceiver chip U2 is connected to the first terminals of the third resistor R3 and the fourth resistor R4, respectively. The second terminal of the third resistor R3 is connected to the first data transmit pin USART1-TX of the main control chip U1, and the second terminal of the fourth resistor R4 is connected to the second data transmit pin USART2-TX of the main control chip U1. The sleep control pin NSLP of the transceiver chip U2 is connected to the second power supply VCC2. The local wake-up input pin NWAKE of the transceiver chip U2 is connected to the first terminal of the fifth resistor R5. The second terminal of the fifth resistor R5 is connected to the first terminal of the sixth resistor R6 and the first terminal of the first switch button K0, respectively. The second terminal of the sixth resistor R6 is connected to the third power supply VCC3, and the second terminal of the first switch button K0 is grounded GN. D. The first data transmission pin TXD of the transceiver chip U2 is connected to the first data reception pin USART1-RX of the main control chip U1. The voltage adjustment pin INH of the transceiver chip U2 is connected to the anode of the first diode D1. The cathode of the first diode D1 is connected to the first end of the seventh resistor R7. The second end of the seventh resistor R7 is connected to the serial communication pin LIN of the transceiver chip U2. The power supply pin BAT of the transceiver chip U2 is connected to the third power supply VCC3 and the power supply pin VCC of the cover motor module 300, respectively. The serial communication pin LIN of the transceiver chip U2 is connected to the first end of the fourth capacitor C4 and the serial communication pin LIN of the cover motor module 300, respectively. The second end of the fourth capacitor C4 is grounded to GND. The ground pin GND of the transceiver chip U2 is grounded.

[0154] Understandably, the transceiver chip U2 can be a transceiver chip used to receive signals and communicate with the outside world, such as TJA1020.

[0155] like Figure 6As shown, the communication module 500 can receive the angle trigger signal output by the main control module 100 through the RTX pin of the transceiver chip U2, and the transceiver chip U2 triggers the angle control signal corresponding to the target mode based on the angle trigger signal. The power supply pin BAT and the serial communication pin LIN of the transceiver chip U2 are respectively connected to the power supply pin VCC and the serial communication pin LIN of the AGS grid motor module 200, thereby realizing the connection with the AGS grid motor module 200 and outputting the angle control signal to the AGS grid motor module 200.

[0156] It should be noted that the power input module of the AGS grid angle display circuit in this embodiment is externally connected to a DC 9-16V voltage to power the mode switching module 400, the main control module 100 and the communication module 500.

[0157] In the specific implementation, an external DC 9-16V voltage, which is the voltage corresponding to the third power supply, can be taken as 12V. The power input module can adopt a buck topology circuit, based on a buck chip, such as MP2359DJ, to output a low ripple voltage, such as 5V. This low ripple voltage can be the voltage of the second power supply mentioned above, and can power the transceiver chip U2 in the communication module 500. At the same time, based on a voltage regulator chip, such as AMS1117, an LDO low-voltage linear regulator circuit can be formed to output the voltage of the first power supply, such as 3.3V. This voltage of the first power supply can power the main control chip U1 in the main control module 100.

[0158] Based on the above embodiments of the AGS grid angle display circuit, a first embodiment of the AGS grid angle display method of the present invention is proposed.

[0159] Reference Figure 7 , Figure 7 This is a flowchart illustrating the first embodiment of the AGS grid angle display method of the present invention.

[0160] In this embodiment, the AGS grille motor angle display method based on the above-described AGS grille angle display circuit includes the following steps:

[0161] Step S10: During normal operation, trigger the automatic calibration signal and perform calibration based on the automatic calibration signal.

[0162] It should be noted that the execution subject of the method in this embodiment can be a computing service device with data processing, network communication, and program execution functions, such as a microcontroller or controller, or it can be an AGS grid angle display device or other electronic device that implements the same or similar functions. The following description uses an AGS grid angle display device (hereinafter referred to as the display device) to illustrate this embodiment and the following embodiments.

[0163] Understandably, the automatic calibration signal can be a signal used for automatic calibration.

[0164] In a practical implementation, the display device can trigger the aforementioned automatic calibration signal during power-on to perform calibration based on the automatic calibration signal.

[0165] Step S20: When calibration is successful, obtain a calibration success signal based on the opening and closing angle of the AGS grid.

[0166] In a specific implementation, the display device can set AutoCalibReq to 1 according to the above-mentioned automatic calibration signal to perform automatic calibration. When the calibration is successful, the AGS grille motor is controlled to rotate automatically one revolution. At the same time, the AGS grille motor sends the opening and closing angle movement signal and the calibration success signal together as a calibration success signal to the display device to achieve communication.

[0167] Step S30: Obtain an angle display signal corresponding to the opening / closing angle based on the calibration success signal.

[0168] It should be noted that the angle display signal can be the signal used to trigger the LCD digital tube to display the angle.

[0169] In a specific implementation, when the display device receives the above-mentioned calibration success signal, it can read the opening and closing angle movement signal in the above-mentioned calibration success signal, and trigger the angle display signal based on the opening and closing angle movement signal.

[0170] Step S40: Display the opening / closing angle via the angle display signal.

[0171] In practical implementation, the display device can use the aforementioned angle display signal to drive the LCD driver chip to drive the LCD digital tube to display the opening and closing angle of the AGS grille in real time, thereby realizing real-time display and monitoring of the opening and closing angle of the AGS grille.

[0172] It should be understood that the aforementioned LCD driver chip can be a chip that drives the LCD digital tube for display, such as the TM1652 chip.

[0173] This embodiment triggers an automatic calibration signal during normal operation and performs calibration based on this signal. Upon successful calibration, a calibration success signal is obtained based on the opening and closing angle of the AGS grille. An angle display signal corresponding to the opening and closing angle is then obtained based on this calibration success signal, and the opening and closing angle is displayed using this angle display signal. Because this embodiment triggers the angle display signal based on the calibration success signal corresponding to the AGS grille's opening and closing angle, and then displays the opening and closing angle based on this angle display signal, compared to the existing technology that uses a motor LIN communication matrix to perform quality inspection of the AGS grille motor, this embodiment is simpler to operate and achieves effective monitoring of the AGS grille's opening and closing angle.

[0174] Other embodiments or specific implementations of the AGS grid angle display method of the present invention can be referred to the above-described method embodiments, and will not be repeated here.

[0177] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods of the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.
