[0002] In the related technology, with the rapid development of the vehicle industry, users' requirements for vehicle experience have also increased. Conventional mechanical charging port covers can no longer meet users' demand for convenient and high-tech vehicles, so some vehicles are equipped with electric charging port covers, but the operation time of the electric charging port cover is long when opening and closing, and the electric charging port cover will be accompanied by continuous mechanical actuation sounds such as motor sounds when rotating, which can easily cause discomfort and irritation to users, thereby greatly reducing the user's comfort and experience.

At the same time, the charging port cover is accelerated when it rotates to the second stage, which can shorten the operation time of the charging port cover opening, thereby shortening the time of the mechanical actuation sound generated when the charging port cover rotates, thereby reducing the user's annoyance with the actuation sound, and improving the user's comfort and experience.

[0012] According to some embodiments of the present invention, when the proportion of the opening stroke of the charging port cover in the entire rotation stroke of the charging port cover reaches a preset value, the charging port cover switches from the first stage of opening to the second stage of opening.

[0013] According to some embodiments of the present invention, in the second stage of opening the charging port cover, when the second speed reaches the maximum value, the working current of the charging port cover actuator driving the charging port cover to open reaches I 1 The vehicle charging port cover control method further includes: determining that the working current of the charging port cover actuator driving the charging port cover to open reaches I max , where I max >I 1 ; Control the charging port cover to stop rotating.

At the same time, the charging port cover is accelerated when it rotates to the second stage, which can shorten the operation time of the charging port cover opening, thereby shortening the time of the mechanical actuation sound generated when the charging port cover rotates, thereby reducing the user's annoyance of the actuation sound, and improving the user's comfort and experience.

[0016] The vehicle according to an embodiment of the present invention comprises: a vehicle body, a charging port cover, the above-mentioned charging port cover controller, a charging port cover actuator and a receiving module.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] Reference below Figure 1-Figure 3 A method for controlling a vehicle charging port cover according to an embodiment of the present invention is described.

[0027] like Figure 2 As shown, a method for controlling a vehicle charging port cover according to an embodiment of the present invention includes:

[0028] Get the opening instruction of the charging port cover;

[0029] The charging port cover is controlled to open, and rotates at a first speed in the first stage of opening, and rotates at a second speed in the second stage of opening, and the second speed is greater than the first speed.

[0030] Specifically, Figure 1 and Figure 2As shown, the above-mentioned control method of the vehicle charging port cover is used to control the vehicle, the vehicle includes a vehicle body and a charging port cover, the charging port cover is rotatably arranged on the vehicle body, and the vehicle body is also provided with a charging port cover controller and a receiving module, the charging port cover controller is used to execute the control method of the vehicle charging port cover, the receiving module is arranged on the vehicle body or the charging port cover, and is used to obtain the switch instruction of the charging port cover, and the receiving module is connected to the charging port cover controller in communication. When the receiving module receives the instruction from the user to open the charging port cover, the receiving module will transmit the signal of the opening instruction to the charging port cover controller, and the charging port cover controller will generate the control instruction to open the charging port cover. Among them, the receiving module can be specifically a switch button arranged on the charging port cover. When the charging port cover is closed, the user presses the switch button, and the receiving module obtains the opening instruction of the charging port cover. Of course, the receiving module can also be a proximity sensor. When the charging port cover is closed, the proximity sensor senses that the user is close to the charging port cover and converts it into a signal output to the charging port cover controller, thereby realizing the acquisition of the opening instruction of the charging port cover.

[0031] Furthermore, the vehicle also includes a charging port cover actuator, which is used to drive the charging port cover to rotate. The charging port cover actuator is connected to the charging port cover controller in communication, and can receive control instructions sent by the charging port cover controller and execute corresponding instruction actions. When the charging port cover controller receives a signal from the receiving module to open the charging port cover, the charging port cover controller will generate a control instruction and transmit it to the charging port cover actuator, so that the charging port cover actuator controls the charging port cover to rotate and open. Specifically, the charging port cover actuator can be a motor, and the output shaft of the motor is connected to the rotating shaft of the charging port cover, so that the charging port cover actuator drives the charging port cover to rotate.

[0032] When the charging port cover is opened, its entire rotation stroke can be divided into a first stage and a second stage. The initial stage of opening the charging port cover is the first stage. At this time, the charging port cover controller transmits a control signal to the charging port cover actuator, so that the charging port cover actuator controls the charging port cover to rotate at a first speed. When the charging port cover rotates to the second stage of the entire rotation stroke, the charging port cover controller transmits a control signal to the charging port cover actuator, so that the charging port cover actuator controls the charging port cover to rotate at a second speed, and the second speed is greater than the first speed.

[0033] It is understandable that, through the above control method, the charging port cover rotates at a slower first speed in the first stage just opened, which can avoid the charging port cover colliding with the user's hand that has not been retracted in time due to the excessively fast rotation speed when just opened, thereby ensuring the user's experience and safety. When the charging port cover rotates to the second stage, the charging port cover actuator controls the charging port cover to speed up the rotation speed, which can shorten the operation time of the charging port cover opening, thereby shortening the time of the mechanical actuation sound accompanying the rotation of the charging port cover, avoiding the discomfort and irritation of the user caused by the noise that lasts too long, and then reducing the user's annoyance of the actuation sound, thereby achieving the purpose of improving the user's comfort and experience.

[0034] It should be noted that the rotation speed of the charging port cover is related to the working current of the charging port cover actuator. The greater the working current of the charging port cover actuator, the greater its working power and the greater the rotation speed of the charging port cover. The charging port cover controller can control the change of the rotation speed of the charging port cover by changing the working current of the charging port cover actuator.

[0035] According to the control method of the vehicle charging port cover of the embodiment of the present invention, after obtaining the opening instruction of the charging port cover, the charging port cover is controlled to open, and the charging port cover rotates at a first speed in the first stage of opening, and rotates at a second speed in the second stage of opening, and the second speed is greater than the first speed. This can prevent the charging port cover from colliding with the user's hand that has not been retracted in time due to excessive rotation speed when it is just opened, thereby ensuring the user's experience and safety. At the same time, the charging port cover is accelerated when it rotates to the second stage, which can shorten the operation time of the charging port cover opening, thereby shortening the time of the mechanical actuation sound generated when the charging port cover rotates, thereby reducing the user's annoyance with the actuation sound, and improving the user's comfort and experience.

[0036] In some embodiments, the method for controlling the vehicle charging port cover further includes:

[0037] Get the closing instruction of the charging cover;

[0038] The charging port cover is controlled to be closed, and the cover rotates at a first speed in the first stage of closing, and rotates at a second speed in the second stage of closing, and the second speed is greater than the first speed.

[0039] It is understandable that when the receiving module receives the user's instruction to close the charging port cover, the receiving module will transmit the signal of the closing instruction to the charging port cover controller, and the charging port cover controller will generate a control instruction to close the charging port cover. Among them, the receiving module can be specifically a switch button provided on the charging port cover. When the charging port cover is open, the user presses the switch button, and the receiving module obtains the closing instruction of the charging port cover. Of course, the receiving module can also be a proximity sensor. When the charging port cover is open, the proximity sensor senses that the user is close to the charging port cover and converts it into a signal output to the charging port cover controller, thereby obtaining the closing instruction of the charging port cover.

[0040] Furthermore, when the charging port cover controller receives a signal from the receiving module to close the charging port cover, the charging port cover controller generates a control instruction and transmits it to the charging port cover actuator, so that the charging port cover actuator controls the charging port cover to rotate to close.

[0041] When the charging port cover is closed, its entire rotation stroke can be divided into a first stage and a second stage. The initial stage of closing the charging port cover is the first stage, at which the charging port cover controller transmits a control signal to the charging port cover actuator, so that the charging port cover actuator controls the charging port cover to rotate at a first speed. When the charging port cover rotates to the second stage of the entire rotation stroke, the charging port cover controller transmits a control signal to the charging port cover actuator, so that the charging port cover actuator controls the charging port cover to rotate at a second speed, and the second speed is greater than the first speed.

[0042] It is understandable that, through the above control method, the charging port cover rotates at a slower first speed in the first stage just after closing, which can avoid the charging port cover colliding with the user's hand that has not been retracted in time due to the excessively fast rotation speed when it is just closed, thereby ensuring the user's experience and safety. When the charging port cover rotates to the second stage, the charging port cover actuator controls the charging port cover to speed up the rotation speed, which can shorten the operation time of closing the charging port cover, thereby shortening the time of the mechanical actuation sound accompanying the rotation of the charging port cover, avoiding the discomfort and irritation of the user caused by the noise that lasts too long, thereby reducing the user's annoyance of the actuation sound and improving the user's comfort and experience.

[0043] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, obtaining the opening instruction of the charging cover includes:

[0044] Make sure the switch button on the charging port cover is pressed;

[0045] Or, it is detected that the user's hand is close to the charging port cover.

[0046] It is understandable that a receiving module is provided on the vehicle body or the charging port cover, which is used to obtain the switch instruction of the charging port cover and transmit the signal to the charging port cover controller to generate the corresponding control instruction. The receiving module can be specifically a switch button provided on the charging port cover. When the charging port cover is closed, the user presses the switch button, and the receiving module obtains the instruction that the user needs to open the charging port cover; when the charging port cover is open, the user presses the switch button, and the receiving module obtains the instruction that the user needs to close the charging port cover. Setting a switch button on the charging port cover is simple in structure and easy to implement, and is also convenient for user operation, which can ensure the user's comfort.

[0047] In addition, the receiving module can also be a proximity sensor provided on the charging port cover. When the user approaches the proximity sensor on the charging port cover, the dielectric constant between the user and the proximity sensor changes, and the circuit state of the circuit connected to the proximity sensor changes accordingly. Then the proximity sensor outputs the changed signal to the charging port cover controller for state discrimination and generates corresponding control instructions. For example, when the charging port cover is closed, the user's hand approaches the charging port cover, the proximity sensor senses the hand approaching and converts it into a signal output to the charging port cover controller, and the charging port cover controller generates a control instruction to open the charging port cover. By setting a proximity sensor, the user's hand can be opened or closed by approaching the charging port cover, which can reduce the user's charging process operation links, thereby improving the user's charging experience.

[0048] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, before controlling the charging port cover to open, the method for controlling the vehicle charging port cover also includes:

[0049] Determine that the vehicle meets the preset conditions. This step may be performed after obtaining the opening instruction of the charging port cover, or before obtaining the opening instruction of the charging port cover.

[0050] It is understandable that the vehicle may be provided with a vehicle controller, which is in communication with the charging port cover controller. In addition to receiving the command signal from the receiving module, the charging port cover controller also needs to exchange information with the vehicle controller. The vehicle controller is used to obtain the current vehicle status information of the vehicle and feed the vehicle status information back to the charging port cover controller. In this embodiment, the vehicle status information includes the vehicle's speed, gear position, and door unlocking information. The charging port cover controller combines the command signal from the receiving module and the information feedback from the vehicle controller to determine whether to open the charging port cover and generate corresponding control instructions.

[0051] Specifically, the preset conditions may be that the vehicle speed is 0, the vehicle gear is P, and the door is unlocked. When the vehicle meets the above preset conditions, the charging port cover controller determines that the vehicle is in a state where the charging port cover is allowed to be opened. The above conditions must be met at the same time, and none of them can be missing. Otherwise, the charging port cover controller determines that the charging port cover cannot be opened. Avoiding opening the charging port cover at inappropriate times can ensure the safety of opening the charging port cover of the vehicle.

[0052] In some embodiments of the present invention, Figure 3 As shown, in the first stage of opening the charging port cover, the first speed remains unchanged. In the first stage, the charging port cover rotates at a slower first speed and the first speed remains unchanged, which can better prevent the charging port cover from colliding with the user's hand that has not been retracted in time when it is just opened, thereby better ensuring the user's experience and safety. At the same time, keeping the speed of the charging port cover unchanged in the first stage can also simplify the control link.

[0053] It should be noted that when the charging port cover rotates at the first speed in the first stage, the working current of the charging port cover actuator that drives the charging port cover to open remains unchanged and is maintained at I 0 .

[0054] In some embodiments of the present invention, Figure 3 As shown, in the second stage of opening the charging port cover, the second rotation speed gradually increases or the second rotation speed first gradually increases and then remains unchanged. When the charging port cover rotates, the higher the rotation speed, the greater the noise generated, and the frequency of the mechanical actuation sound changes accordingly. By gradually increasing the rotation speed of the charging port cover in the second stage, it is possible to avoid a sudden increase in the volume of the mechanical actuation sound caused by a surge in the rotation speed of the charging port cover when it enters the second stage from the first stage, and it is also possible to avoid a sudden change in the sound frequency of the mechanical actuation sound causing discomfort and irritation to the user. By gradually changing the volume and frequency of the mechanical actuation sound, it is beneficial for the user to gradually adapt to the changing mechanical actuation sound, thereby helping to ensure the user's comfort.

[0055] In some embodiments of the present invention, Figure 3 As shown, in the second stage of opening the charging port cover, the second rotation speed first gradually increases and then remains unchanged, wherein the state in which the second rotation speed remains unchanged accounts for a in the entire rotation stroke of the charging port cover, and a is 5%-15%.

[0056] If a is less than 5%, the second speed gradually increases in the entire rotation stroke of the charging port cover, and the rotation stroke of the charging port cover at the maximum speed is too short, which cannot fully shorten the operation time of the charging port cover, and cannot ensure the effect of reducing the user's actuation sound annoyance. If a is greater than 15%, the second speed gradually increases in the entire rotation stroke of the charging port cover, and the speed of the second speed gradually increases too fast, which may cause the user discomfort due to excessive increase in noise or too fast change in sound frequency.

[0057] Therefore, keeping a at 5%-15% can not only shorten the operating time of the charging port cover and the time of mechanical actuation sound, ensuring the effect of reducing the user's annoyance of the actuation sound, but also avoid the risk of excessive increase in noise or rapid change in sound frequency causing user discomfort, thereby better improving the user's comfort and experience.

[0058] In some embodiments of the present invention, Figure 3 As shown, when the proportion of the charging port cover opening stroke in the entire rotation stroke of the charging port cover opening reaches a preset value, the charging port cover switches from the first opening stage to the second opening stage.

[0059] Specifically, a position sensor may be provided on the vehicle, and the position sensor is used to detect the rotation position of the charging port cover, and the position sensor is in communication with the charging port cover controller. When the charging port cover controller receives the position signal from the position sensor and determines that the charging port cover rotates to the position of the charging port cover corresponding to the above-mentioned preset value, the charging port cover controller generates a control instruction and transmits it to the charging port cover actuator, so that the charging port cover actuator controls the charging port cover to rotate from the first speed to the second speed. By using the rotation stroke of the charging port cover as the judgment condition for changing the speed of the charging port cover, the positional relationship between the charging port cover and the user can be better grasped, and the charging port cover can be prevented from accelerating and rotating at an inappropriate position and causing a collision with the user, thereby ensuring the safety of the user.

[0060] Preferably, if Figure 3 As shown, the first stage of opening the charging port cover accounts for b in the entire rotation stroke of the charging port cover, and b is 40%-65%.

[0061] If b is less than 40%, there is a risk that the charging cover will collide with the user's hand that has not been retracted in time due to the accelerated rotation speed when it is just opened. If b is greater than 65%, the stroke of the charging cover rotating at the second speed is too short, and the operating time of the charging cover opening cannot be fully shortened, and the effect of reducing the user's actuation sound annoyance cannot be guaranteed. Therefore, keeping b at 40%-65% can not only shorten the operating time of the charging cover opening and the time when the mechanical actuation sound is generated, ensuring the effect of reducing the user's actuation sound annoyance, but also avoid the charging cover from colliding with the user's hand that has not been retracted in time due to the accelerated rotation speed when it is just opened, thereby better ensuring the user experience and safety.

[0062] In some embodiments of the present invention, Figure 3 As shown, in the second stage of opening the charging port cover, when the second speed reaches the maximum value, the working current of the charging port cover actuator that drives the charging port cover to open reaches I 1 , the control method of the vehicle charging port cover also includes:

[0063] Make sure that the operating current of the charging port cover actuator that drives the charging port cover to open reaches I max , where I max >I 1 ;

[0064] Control the charging port cover to stop rotating.

[0065] It is understandable that the greater the working current of the charging port cover actuator, the greater its working power, the faster the rotation speed of the charging port cover, the greater the noise generated, and the frequency of the mechanical actuation sound changes accordingly. 1 The operating current of the charging port cover actuator at the maximum rotation speed of the charging port cover that is acceptable to the user, which has been confirmed through tests, can shorten the operating time of the charging port cover as much as possible while ensuring the user's hearing sense.

[0066] When the charging port cover actuator drives the charging port cover to open, if it is detected that the working current of the charging port cover actuator reaches I max , indicating that the charging port cover collides with an obstacle. At this time, the charging port cover controller issues a control command to stop the charging port cover actuator, that is, the working current of the charging port cover actuator drops to 0, thereby controlling the charging port cover to stop rotating, avoiding the charging port cover from colliding and injuring a person's hand, or preventing the charging port cover from being damaged by colliding with an obstacle. It should be noted that I max >I 1 , and I max It is the maximum operating current that the charging port cover actuator can reach when working normally, which is determined by the performance of the specific charging port cover actuator used.

[0067] According to the charging port cover controller of the embodiment of the present invention, the charging port cover controller executes the above-mentioned vehicle charging port cover control method.

[0068] According to the charging port cover controller of the embodiment of the present invention, after obtaining the opening instruction of the charging port cover, the charging port cover is controlled to open, and the charging port cover is controlled to rotate at a first speed in the first stage of opening, and at a second speed in the second stage of opening, and the second speed is greater than the first speed, so that the charging port cover can be prevented from colliding with the user's hand that has not been retracted in time due to excessive rotation speed when it is just opened, thereby ensuring the user's experience and safety. At the same time, the charging port cover is accelerated when it rotates to the second stage, which can shorten the operation time of the charging port cover opening, thereby shortening the time of the mechanical actuation sound generated when the charging port cover rotates, thereby reducing the user's annoyance of the actuation sound, and improving the user's comfort and experience.

[0069] A vehicle according to an embodiment of the present invention is described below, wherein the vehicle operates according to the above-mentioned method for controlling a vehicle charging port cover.

[0070] A vehicle according to an embodiment of the present invention includes: a vehicle body, a charging port cover, the above-mentioned charging port cover controller, a charging port cover actuator, and a receiving module.

[0071] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, the vehicle includes a vehicle body and a charging port cover, the charging port cover is rotatably arranged on the vehicle body, and a charging port cover controller and a receiving module are also arranged on the vehicle body. The charging port cover controller is used to execute the control method of the vehicle charging port cover, and the receiving module is arranged on the vehicle body or the charging port cover, and is used to obtain the switch instruction of the charging port cover, and the receiving module is connected to the charging port cover controller in communication. When the receiving module receives the instruction from the user to open the charging port cover, the receiving module transmits the signal of the opening instruction to the charging port cover controller, and the charging port cover controller generates a control instruction to open the charging port cover. Among them, the receiving module can be specifically a switch button arranged on the charging port cover. When the charging port cover is closed, the user presses the switch button, and the receiving module obtains the opening instruction of the charging port cover. Of course, the receiving module can also be a proximity sensor. When the charging port cover is closed, the proximity sensor senses that the user is close to the charging port cover and converts it into a signal output to the charging port cover controller, thereby obtaining the opening instruction of the charging port cover.

[0072] Furthermore, the vehicle also includes a charging port cover actuator, which is used to drive the charging port cover to rotate. The charging port cover actuator is connected to the charging port cover controller in communication, and can receive control instructions sent by the charging port cover controller and execute corresponding instruction actions. When the charging port cover controller receives a signal from the receiving module to open the charging port cover, the charging port cover controller will generate a control instruction and transmit it to the charging port cover actuator, so that the charging port cover actuator controls the charging port cover to rotate and open. Specifically, the charging port cover actuator can be a motor, and the output shaft of the motor is connected to the rotating shaft of the charging port cover, so that the charging port cover actuator drives the charging port cover to rotate.

[0073] When the charging port cover is opened, its entire rotation stroke can be divided into a first stage and a second stage. The initial stage of opening the charging port cover is the first stage. At this time, the charging port cover controller transmits a control signal to the charging port cover actuator, so that the charging port cover actuator controls the charging port cover to rotate at a first speed. When the charging port cover rotates to the second stage of the entire rotation stroke, the charging port cover controller transmits a control signal to the charging port cover actuator, so that the charging port cover actuator controls the charging port cover to rotate at a second speed, and the second speed is greater than the first speed.

[0074] It is understandable that, through the above control method, the charging port cover rotates at a slower first speed in the first stage just opened, which can avoid the charging port cover colliding with the user's hand that has not been retracted in time due to the excessively fast rotation speed when just opened, thereby ensuring the user's experience and safety. When the charging port cover rotates to the second stage, the charging port cover actuator controls the charging port cover to speed up the rotation speed, which can shorten the operation time of the charging port cover opening, thereby shortening the time of the mechanical actuation sound accompanying the rotation of the charging port cover, avoiding the discomfort and irritation of the user caused by the noise that lasts too long, and then reducing the user's annoyance of the actuation sound, thereby achieving the purpose of improving the user's comfort and experience.

[0075] It should be noted that the rotation speed of the charging port cover is related to the working current of the charging port cover actuator. The greater the working current of the charging port cover actuator, the greater its working power and the greater the rotation speed of the charging port cover. The charging port cover controller can control the change of the rotation speed of the charging port cover by changing the working current of the charging port cover actuator.

[0076] According to the vehicle of the embodiment of the present invention, after obtaining the opening instruction of the charging port cover, the charging port cover is controlled to open, and the charging port cover rotates at a first speed in the first stage of opening, and rotates at a second speed in the second stage of opening, and the second speed is greater than the first speed, which can avoid the charging port cover from colliding with the user's hand that has not been retracted in time due to excessive rotation speed when it is just opened, thereby ensuring the user's experience and safety. At the same time, the charging port cover is accelerated when it rotates to the second stage, which can shorten the operation time of the charging port cover opening, thereby shortening the time of the mechanical actuation sound accompanying the charging port cover when it rotates, thereby reducing the user's annoyance of the actuation sound, and improving the user's comfort and experience.

[0077] In some embodiments of the present invention, Figure 1 As shown, the receiving module includes a button or a proximity sensor. The receiving module can be a switch button provided on the charging port cover. When the charging port cover is closed, the user presses the switch button, and the receiving module obtains the instruction that the user needs to open the charging port cover; when the charging port cover is open, the user presses the switch button, and the receiving module obtains the instruction that the user needs to close the charging port cover. Setting a switch button on the charging port cover is simple in structure and easy to implement, and is also convenient for user operation, which can ensure the user experience.

[0078] In addition, the receiving module can also be a proximity sensor provided on the charging port cover. When a person's hand approaches the proximity sensor on the charging port cover, the dielectric constant between the person's hand and the proximity sensor changes, and the circuit state of the circuit connected to the proximity sensor changes accordingly. Then the proximity sensor outputs the changed signal to the charging port cover controller for state discrimination and generates corresponding control instructions. By providing a proximity sensor, the user can open or close the charging port cover by approaching the charging port cover, which can reduce the operation links of the user's charging process and thus improve the user's charging experience.

[0079] In some embodiments of the present invention, Figure 1 As shown, the vehicle also includes a vehicle controller, which is arranged on the vehicle body, and the charging port cover controller is communicatively connected with the vehicle controller. The vehicle controller is used to obtain the current vehicle status information of the vehicle and feed back the vehicle status information to the charging port cover controller. In this embodiment, the vehicle status information includes the vehicle speed, gear position and door unlocking information. The charging port cover controller combines the command signal of the receiving module and the information feedback of the vehicle controller to determine whether to open the charging port cover and generate corresponding control instructions. Specifically, when the vehicle controller transmits the signal that the vehicle speed is 0, the vehicle gear position is P and the door is in the unlocked state to the charging port cover controller, the charging port cover controller determines that the vehicle is in a state that allows the charging port cover to be opened, avoids opening the charging port cover at an inappropriate time, and can ensure the safety of the vehicle opening the charging port cover.

[0080] In some embodiments of the present invention, Figure 1 As shown, the vehicle also includes a position sensor, which is arranged on the vehicle body or the charging port cover and is used to detect the rotation position of the charging port cover. Thus, it is possible to accurately determine whether the charging port cover is in the first stage or the second stage of the rotation stroke, so as to ensure that the control method of the vehicle charging port cover operates stably and accurately. Among them, the position sensor is connected to the charging port cover controller for communication. After the position sensor detects the rotation position of the charging port cover, it transmits the position information to the charging port cover controller, and the charging port cover controller thereby determines whether the charging port cover is in the first stage or the second stage of the rotation stroke, thereby generating corresponding control instructions.
