[0029] <Control system of charging port cover>

[0030] Referring to Figure 1 As shown, the embodiment of the present disclosure provides a control system of a charging port cover, which includes at least one triggering module, at least one detecting module, and a control module.

[0031] The triggering module and the detecting module are in communication connection with the control module. The triggering module is configured to trigger an operation request for the charging port cover. The detecting module is configured to detect a motion state of the charging port cover. The control module is configured to control the charging port cover to open / close in response to the operation request. The control module is further configured to control an opening process / closing process of the charging port cover according to a detection result of the detecting module.

[0032] The charging port cover in the embodiment of the present disclosure can be electrically driven and can be opened or closed under the action of a motor. The charging port cover in the embodiment of the present disclosure can be an outer cover of a charging port. The motor can be a motor of the outer cover of the charging port. The motor can be installed inside the charging port cover and connected with the charging port cover to control driving the charging port cover to open or close.

[0033] In one example, the control module is a domain controller of the vehicle. The domain controller interacts with multiple systems of the vehicle through a CAN line, including interacting with a charging module of a charging system. The charging module of the charging system is installed inside the vehicle to feed back the charging status of the vehicle, such as whether it is fast charging or slow charging, etc. The charging module interacts with the domain controller through the CAN line, and the domain controller can analyze and process the signal request of the charging system to control the charging process.

[0034] In one example, the at least one trigger module includes at least one of a central control screen, a key, an external switch, a gear switch, a charging module, and a battery management system (BMS). The trigger module is used to trigger an operation request for the charging port cover, for example, the trigger module is used to trigger an opening request for the charging port cover, or the trigger module is used to trigger a closing request for the charging port cover.

[0035] The external switch is a control switch of the charging port cover, and the external switch interacts with the domain controller through a hard line. The external switch is used for a user to manually trigger an operation request for the charging port cover. The external switch is arranged on the vehicle body shell, for example, installed on the outer side of the charging port cover.

[0036] The key can be a remote key, and the position of the remote key can be fed back to the domain controller through a key detection antenna of the vehicle.

[0037] The central control screen is used to open and close the charging port cover, and interacts with the domain controller through a CAN line. In one example, the central control screen triggers an opening request for the charging port cover when receiving an instruction of a user to open the charging port cover. In one example, the central control screen triggers a closing request for the charging port cover when receiving an instruction of a user to close the charging port cover. That is, the user can operate the central control screen in the vehicle to open or close the charging port cover. In one example, the central control screen triggers a closing request for the charging port cover when receiving an instruction to set the vehicle to a car washing mode. That is, the user can operate the central control screen in the vehicle to set the vehicle to the car washing mode, and since the charging port cover needs to be closed in the car washing mode to ensure the safety of the circuit system, the central control screen triggers a closing request for the charging port cover to control the charging port cover to close when receiving an instruction to set the vehicle to the car washing mode.

[0038] The gear switch is used to obtain a gear state and output a gear signal to the domain controller. In one example, the control system of the charging port cover can further include a vehicle control unit (VCU), and the VCU feeds back the gear signal to the domain controller. In one example, the vehicle can be charged in a parking gear condition, and if the vehicle is in a non-parking gear, the vehicle is prohibited to be charged, and the domain controller controls the charging port cover to remain in a closed state.

[0039] Referring to Figure 1 As shown, the at least one detection module includes a first detection module for detecting the position of the charging port cover and / or the rotating speed of the motor of the charging port cover. The first detection module may, for example, be a Hall sensor installed on the motor of the charging port cover for detecting the opening angle of the charging port cover and / or the rotating speed of the motor of the charging port cover and feeding back the detection result to the domain controller. The first detection module can detect whether the charging port cover reaches the closed position, and when the detection result thereof indicates that the angle of the charging port cover is 0 degree, the first detection module determines that the charging port cover is in the closed position.

[0040] Referring to Figure 1 As shown, the at least one detection module includes a second detection module for detecting whether the charging port cover reaches the closed position. The second detection module may, for example, be a position switch, which is triggered to output a specific trigger signal when the charging port cover is closed from the open state to be flush with the side wall of the vehicle, so as to determine that the charging port cover is in the closed position at this time. That is, the second detection module can identify whether the charging port cover reaches the closed position in the closing process of the charging port cover, so as to ensure that the charging port cover is flush with the side wall of the vehicle. When the second detection module senses that the charging port cover reaches the closed position, the control module sends a closed position calibration signal to the first detection module, and the first detection module can calibrate the closed position data thereof, so as to facilitate more accurate opening / closing of the charging port cover by the motor subsequently.

[0041] Referring to Figure 1 As shown, the control system of the charging port cover may further include an indicator light. The indicator light is in communication connection with the domain controller. The indicator light is arranged on the charging port cover and / or the quarter window arranged on the rear of the vehicle. The indicator light interacts with the domain controller through the LIN line, and when the user presses the outer switch to open / close the port cover, the domain controller lights up the indicator light to feedback to the user.

[0042] <Control method of charging port cover>

[0043] The control method of the charging port cover provided by the embodiments of the present disclosure can be applied to the control system of the charging port cover in the above embodiments and can be executed by the control module in the above embodiments.

[0044] Referring to Figure 2 As shown, the control method of the charging port cover includes steps S002-S004.

[0045] Step S002, receiving a control request of a trigger module of a vehicle for the charging port cover, and controlling the motor of the charging port cover to open or close the charging port cover according to the control request.

[0046] Step S004, during the process of controlling the motor to open or close the charging port cover, if the rotating speed of the motor is less than a preset first rotating speed threshold and the current of the motor is greater than a preset first current threshold, the motor is controlled to rotate in the opposite direction to make the charging port cover rotate in the opposite direction by a preset angle.

[0047] In the embodiments of the present disclosure, the rotating speed of the motor can be acquired in various ways. For example, the rotating speed of the motor can be measured by the first detection module mentioned above. For example, a Hall sensor or an optical rotary speed sensor is arranged on the motor of the charging port cover to measure the rotating speed of the motor.

[0048] The following will be described in detail:

[0049] In one example, referring to FIG. 1, the process of opening the charging port cover provided by the embodiments of the present disclosure includes steps S01-S07. Figure 3 As shown, the receiving vehicle's trigger module controls the request of the charging port cover, and controls the motor of the charging port cover to open or close the charging port cover according to the control request, including steps S102-S104.

[0050] Step S102, when receiving the opening request of the charging port cover from any one of the vehicle's trigger modules, it is determined whether multiple opening conditions are met at the same time.

[0051] Step S104, in the case where multiple opening conditions are met at the same time, the motor of the charging port cover is controlled to open the charging port cover.

[0052] In one example, the multiple opening conditions include that the whole vehicle control logic is in an unlocked state, the vehicle is in a non-washing mode, and the vehicle is in a parking gear. In one example, the multiple opening conditions include that the key is located within a preset range of the vehicle, the motor is in a non-heat protection state, the vehicle is in a non-washing mode, and the vehicle is in a parking gear. In one example, the multiple opening conditions further include that the motor is in a non-heat protection state.

[0053] In one example, referring to FIG. 1, the process of opening the charging port cover provided by the embodiments of the present disclosure includes steps S01-S07. Figure 4 As shown, the process of opening the charging port cover provided by the embodiments of the present disclosure includes steps S01-S07.

[0054] Step S01, at least one trigger module triggers an opening request of the charging port cover.

[0055] Step S02, the domain controller receives the opening request;

[0056] Step S03, the domain controller collects a whole vehicle logic state signal, and when the whole vehicle logic state signal is a locking state signal, step S04 is entered, and when the whole vehicle logic state signal is an unlocking state signal, step S05 is entered.

[0057] Step S04, it is judged whether the key is located in the preset range of the vehicle, that is, it is determined whether the key can be detected. If the key is not located in the preset range of the vehicle, step S08 is entered. If the key is located in the preset range of the vehicle, step S05 is entered.

[0058] Step S05, the domain controller judges whether the motor is in the thermal protection state through the energization duration of the motor. If the motor is in the thermal protection state, step S08 is entered. If the motor is in the non-thermal protection state, step S06 is entered.

[0059] Step S06, the domain controller judges the position of the charging port cover through the signal output by the first detection module. When the charging port cover is in the fully open position, step S08 is entered. When the charging port cover is not in the fully open position, that is, when the charging port cover is in the closed position or the half-open position, step S07 is entered.

[0060] Step S07, the motor of the charging port cover is controlled to open the charging port cover.

[0061] Step S08, the domain controller does not respond to the opening request. The domain controller does not respond to the opening request, that is, does not perform the operation of opening the charging port cover.

[0062] For the charging port cover, there are a closed position, a fully open position, an outer opening limit position, and an inner retraction limit position. The closed position is the position of the charging port cover when it is closed. The first detection module can detect the angle of the charging port cover, and when its detection result represents that the angle of the charging port cover is 0 degrees, the first detection module determines that the charging port cover is in the closed position. The position switch can also detect whether the charging port cover is in the closed position. The fully open position is the maximum outer opening position of the charging port cover set on the software level, and the outer opening limit position is the maximum outer opening position that the charging port cover can reach under the mechanical structure restriction. The angle of the outer opening limit position is greater than the angle of the fully open position, for example, the outer opening limit position is 100 degrees, and the fully open position is 90 degrees. The inner retraction limit position is the inner retraction limit position of the charging port cover limited by the body side.

[0063] Optionally, the control method of the charging port cover further comprises step S202. In the process of controlling the motor of the charging port cover to open the charging port cover, if the detection result of the first detection module indicates that the rotating speed of the motor is less than the preset rotating speed threshold and the current of the motor is greater than the preset current threshold, the motor is controlled to rotate in the opposite direction to make the charging port cover retract inward by a preset angle. In this example, the rotating speed of the motor is less than the preset first rotating speed threshold and the current of the motor is greater than the preset first current threshold, indicating that the charging port cover collides with an obstacle, and the motor is controlled to rotate in the opposite direction by a preset angle. That is, in the process of controlling the motor of the charging port cover to open the charging port cover, if the rotating speed of the motor is less than the preset rotating speed threshold and the current of the motor is greater than the preset current threshold, it indicates that the outside of the port cover collides with an obstacle, and at this time the motor is controlled to rotate in the opposite direction to make the charging port cover close by a preset angle. In this way, the charging port cover and the obstacle are separated by a certain distance, which is convenient for removing the obstacle while not damaging the charging port cover; in the process of controlling the motor of the charging port cover to close the charging port cover, if the rotating speed of the motor is less than the preset rotating speed threshold and the current of the motor is greater than the preset current threshold, it indicates that the inside of the port cover collides with an obstacle, and if the obstacle is a human hand, there may be a risk of injury. At this time, the motor is controlled to rotate in the opposite direction to make the charging port cover open by a preset angle. In this way, the charging port cover and the obstacle are separated by a certain distance, which is convenient for the human hand to move away and avoid the risk of injury.

[0064] In one example, referring to FIG. 1, Figure 5 As shown in FIG. 1, the opening process of the charging port cover provided by the embodiments of the present disclosure includes steps S11-S14.

[0065] Step S11, in the process of controlling the motor of the charging port cover to open the charging port cover, the rotating speed of the motor and the current of the motor are obtained.

[0066] Step S12, in the case where the opening angle of the charging port cover is less than or equal to the first angle threshold, if the rotating speed of the motor is less than the preset first rotating speed threshold and the current of the motor is greater than the preset first current threshold, the motor is controlled to rotate in the opposite direction to make the charging port cover retract inward by a preset angle.

[0067] In the case where the opening angle of the charging port cover is less than or equal to the first angle threshold, if the rotating speed of the motor is less than the preset first rotating speed threshold and the current of the motor is greater than the preset first current threshold, it indicates that the charging port cover collides with an obstacle, and the motor is controlled to rotate in the opposite direction to make the charging port cover retract inward by a preset angle. For example, when the charging port cover moves to a position of opening outward by 120 degrees, if it is determined that the charging port cover collides with an obstacle, the motor is controlled to rotate in the opposite direction to make the charging port cover retract inward by 30 degrees, so that the charging port cover stays at a position of opening outward by 90 degrees. In this way, the charging port cover is protected, and safety hazards caused by the charging port cover to the surrounding environment and personnel are prevented.

[0068] Step S13, if the rotation speed of the motor is less than the preset second rotation speed threshold and the current of the motor is greater than the preset second current threshold, stop driving the motor in the case that the opening angle of the charging port cover is greater than the first angle threshold.

[0069] If the rotation speed of the motor is less than the preset second rotation speed threshold and the current of the motor is greater than the preset second current threshold, it means that the charging port cover reaches the outer opening limit position, and then the motor is stopped to protect the motor.

[0070] Step S14, stop driving the motor in the case that the opening angle of the charging port cover reaches the second angle threshold.

[0071] The first rotation speed threshold, the second rotation speed threshold, the first current threshold, and the second current threshold can be set in advance by actual measurement or simulation experiment. The second rotation speed threshold is less than the first rotation speed threshold, and the second current threshold is greater than the first current threshold. The second angle threshold is greater than the first angle threshold. For example, the first angle threshold is 85 degrees, and the second angle threshold is 90 degrees.

[0072] That is, in the process of driving the charging port cover to open, when the angle of the charging port cover is between 0 degrees and 85 degrees, the first rotation speed threshold and the first current threshold are used to determine whether the charging port cover hits an obstacle. If it hits, the motor is controlled to rotate in the opposite direction to make the charging port cover retract inward by a preset angle. After the angle of the charging port cover reaches 85 degrees or more, the second rotation speed threshold and the second current threshold are used to determine whether the charging port cover reaches the outer opening limit position. If it reaches the outer opening limit position, the motor is stopped to prevent damage to the motor. In the embodiment of the present disclosure, the second angle threshold can correspond to the fully open position. In the case that the opening angle of the charging port cover reaches the second angle threshold, the motor is stopped.

[0073] In the embodiment of the present disclosure, the opening angle of the charging port cover and the rotation speed of the motor can be obtained by the first detection module, that is, by the Hall sensor.

[0074] In one example, the control module receives a control request of the triggering module of the vehicle to the charging port cover, and controls the motor of the charging port cover to open or close the charging port cover according to the control request, including steps S302-S304.

[0075] Step S302, at least one triggering module triggers a closing request to the charging port cover.

[0076] Step S304, the control module controls the motor of the charging port cover to close the charging port cover upon receiving the closing request. In one example, the control module controls the motor to retract the charging port cover inward until the charging port cover reaches the closed position. In this example, whether the charging port cover reaches the closed position can be determined by the detection result of the first detection module or the second detection module.

[0077] Optionally, the control method of the charging port cover further includes step S402. Step 402, during the process of controlling the motor of the charging port cover to close the charging port cover, if the detection result of the first detection module indicates that the rotating speed of the motor is less than the preset rotating speed threshold and the current of the motor is greater than the preset current threshold, the control module controls the motor to rotate in the opposite direction to make the charging port cover open outward by a preset angle.

[0078] In one example, referring to FIG. 4, the closing process of the charging port cover provided by the embodiments of the present disclosure includes steps S21-S23. Figure 6

[0079] Step S21, during the process of controlling the motor of the charging port cover to close the charging port cover, the rotating speed of the motor and the current of the motor are obtained.

[0080] Step S22, if the rotating speed of the motor is less than the preset first rotating speed threshold and the current of the motor is greater than the preset first current threshold, the control module controls the motor to rotate in the opposite direction to make the charging port cover open outward by a preset angle.

[0081] The rotating speed of the motor being less than the preset first rotating speed threshold and the current of the motor being greater than the preset first current threshold indicate that the charging port cover collides with an obstacle, and the control module controls the motor to rotate in the opposite direction to make the charging port cover open outward by a preset angle. For example, when the charging port cover is being closed and the charging port cover moves inward to a position where the charging port cover is opened outward by 60 degrees, if it is determined that the charging port cover collides with an obstacle, the control module controls the motor to rotate in the opposite direction to make the charging port cover open outward by another 30 degrees, so that the charging port cover stays at a position where the charging port cover is opened outward by 90 degrees. In this way, the charging port cover is protected, and the charging port cover is prevented from causing a safety hazard to the surrounding environment and personnel.

[0082] Step S23, when the charging port cover reaches the closed position, the driving of the motor is stopped. In this example, whether the charging port cover reaches the closed position can be determined by the detection result of the first detection module or the second detection module.

[0083] In one example, referring to FIG. 4, the closing process of the charging port cover provided by the embodiments of the present disclosure includes steps P11-P14. Figure 7

[0084] Step P11, during the process of controlling the motor of the charging port cover to close the charging port cover, the rotating speed of the motor and the current of the motor are obtained. ​​

[0085] Step P12, if the rotation speed of the motor is less than a preset first rotation speed threshold and the current of the motor is greater than a preset first current threshold, the motor is controlled to rotate in the opposite direction to make the charging port cover open outward by a preset angle when the opening angle of the charging port cover is greater than or equal to the fourth angle threshold.

[0086] When the opening angle of the charging port cover is greater than or equal to the fourth angle threshold, the rotation speed of the motor is less than the preset first rotation speed threshold and the current of the motor is greater than the preset first current threshold, it indicates that the charging port cover collides with an obstacle, the domain controller stops driving the motor, and then drives the motor to rotate in the opposite direction to make the charging port cover open outward by a preset angle. For example, when the charging port cover is closed and the charging port cover moves inward to a position of 60 degrees of opening outward, if it is determined that the charging port cover collides with an obstacle, the motor is controlled to rotate in the opposite direction to make the charging port cover open outward by another 30 degrees, so that the charging port cover stays at a position of 90 degrees of opening outward. In this way, the charging port cover is protected, and safety hazards caused by the charging port cover to the surrounding environment and personnel are also prevented.

[0087] Step P13, if the rotation speed of the motor is less than a preset second rotation speed threshold and the current of the motor is greater than a preset second current threshold, the motor is stopped from being driven when the opening angle of the charging port cover is less than the fourth angle threshold.

[0088] When the opening angle of the charging port cover is less than the fourth angle threshold, if the rotation speed of the motor is less than the preset second rotation speed threshold and the current of the motor is greater than the preset second current threshold, it indicates that the charging port cover reaches an inward retraction limit position, and then the domain controller stops driving the motor to protect the motor. The inward retraction limit position is an inward retraction limit position where the charging port cover is limited by the side wall of the vehicle body.

[0089] Step P14, the motor is stopped from being driven when the charging port cover reaches a closed position.

[0090] In this example, whether the charging port cover reaches the closed position can be determined by the detection result of the first detection module or the second detection module. The first rotation speed threshold, the second rotation speed threshold, the first current threshold, and the second current threshold can be preset by actual measurement or simulation experiment. The second rotation speed threshold is less than the first rotation speed threshold, and the second current threshold is greater than the first current threshold. The fourth angle threshold is a small angle threshold, for example, the fourth angle threshold can be between 5-10 degrees.

[0091] In one example, referring to FIG. 1, the control method of the charging port cover further includes steps P21-P22. Figure 8

[0092] ​Step P21, in the process of controlling the motor to open or close the charging port cover, the rotation speed of the motor and the opening angle of the charging port cover are acquired by the first detection module. In the process of controlling the motor to close the charging port cover, whether the charging port cover reaches the closed position is determined by the second detection module.

[0093] Step P22, when the detection result of the second detection module indicates that the charging port cover reaches the closed position, a closed position calibration signal is sent to the first detection module. The first detection module is a Hall sensor arranged on the motor, and the second detection module is a position switch.

[0094] When the detection result of the second detection module indicates that the charging port cover reaches the closed position, the control module sends a closed position calibration signal to the first detection module. The first detection module can calibrate its own closed position data according to the closed position calibration signal, so as to more accurately help the motor open / close the charging port cover in the future. In one example, the control module counts the number of times the charging port cover is closed. When the number of times the charging port cover is closed reaches a preset threshold, the first detection module is calibrated once in the above manner, and the number of times the charging port cover is closed is cleared. That is, the first detection module is calibrated once by the second detection module every time the number of times the charging port cover is closed reaches a preset number.

[0095] Optionally, the charging port cover can be closed when the vehicle enters a non-parking gear to close the charging port cover in time when the user forgets to close the charging port after charging. The at least one trigger module triggers a closing request for the charging port cover, including: when the gear switch is adjusted to a non-parking gear, a first closing request for the charging port cover is triggered. The control module determines whether the charging port cover is in an open state when receiving the first closing request, and controls the motor of the charging port cover to close the charging port cover in the case that the charging port cover is in the open state.

[0096] Optionally, the charging port cover is prohibited to be opened when the vehicle is in a car washing mode to ensure the safety of the circuit of the vehicle. The at least one trigger module triggers a closing request for the charging port cover, including: when the central control screen receives an instruction to set the vehicle to a car washing mode, a second closing request for the charging port cover is triggered. The control module determines whether the charging port cover is in an open state when receiving the second closing request, and controls the motor of the charging port cover to close the charging port cover in the case that the charging port cover is in the open state.

[0097] In one example, referring to FIG. 8, the process of closing the charging port cover provided by the embodiments of the present disclosure includes steps S31-S33. Figure 9

[0098] Step S31, the domain controller receives the first closing request or the second closing request.

[0099] ​Step S32, the domain controller determines whether the charging port cover is in an open state.

[0100] Step S33, the domain controller controls the motor of the charging port cover to close the charging port cover in the case that the charging port cover is in the open state. The first closing request is a closing request triggered when the gear switch is adjusted to a non-parking gear. The second closing request is a closing request triggered when the central control screen receives an instruction to set the vehicle in a car washing mode.

[0101] Optionally, the at least one triggering module triggers an opening request for the charging port cover, including: the outer switch triggering a first opening request for the charging port cover. The control module lights up the indicator light in the case that the first opening request is received and all opening conditions are met.

[0102] In one example, referring to FIG. 4, Figure 10 The feedback process of the indicator light when the charging port cover is opened provided by the embodiments of the present disclosure includes steps S41-S45.

[0103] Step S41, the outer switch triggers a first opening request for the charging port cover.

[0104] Step S42, the domain controller receives the first opening request.

[0105] Step S43, the domain controller determines whether all opening conditions are met. If yes, proceed to step S44. If no, proceed to step S45.

[0106] Step S44, the domain controller controls the motor of the charging port cover to open the charging port cover, and lights up the indicator light.

[0107] Step S45, the domain controller does not respond to the first opening request, that is, does not perform the operation of opening the charging port cover.

[0108] Optionally, the outer switch triggers a third closing request for the charging port cover. The control module lights up the indicator light when the third closing request is received.

[0109] Optionally, the charging port cover can be automatically closed when the charging gun is unplugged. The at least one triggering module triggers a closing request for the charging port cover, including: the charging module triggering a fourth closing request for the charging port cover when detecting that the charging port is disconnected from the charging gun. The control module determines whether the charging port cover is in an open state when the fourth closing request is received, and controls the motor of the charging port cover to close the charging port cover in the case that the charging port cover is in the open state. In one example, the charging module triggers the fourth closing request for the charging port cover when the time length during which the charging port is disconnected from the charging gun exceeds a preset time length threshold. The preset time length threshold is, for example, 10 seconds.

[0110] In one example, referring to Figure 11 The trigger module of the receiving vehicle requests the control of the charging port cover, and the motor of the charging port cover opens or closes the charging port cover according to the control request, including steps P31-P32.

[0111] Step P31, when receiving the second opening request, it is judged whether the charging port cover is already in an open state and the opening angle is greater than or equal to a third angle threshold. The second opening request is an opening request triggered by the battery management module.

[0112] Step P32, if no, the motor of the charging port cover opens the charging port cover to the third angle threshold. If yes, the second opening request is not responded.

[0113] Referring to Figure 12 The battery management module triggers the process of opening the charging port cover due to the low battery power, including steps S51-S56.

[0114] Step S51, the battery management module triggers the second opening request because the battery power is lower than a first power threshold.

[0115] Step S52, the domain controller receives the second opening request.

[0116] Step S53, the domain controller judges whether all the opening conditions are met. If yes, go to step S54. If no, go to step S56.

[0117] Step S54, the domain controller judges whether the charging port cover is already in an open state and the opening angle is greater than or equal to a third angle threshold according to the Hall signal of the first detection module. If yes, go to step S56. If no, go to step S55.

[0118] Step S55, the motor of the charging port cover opens the charging port cover to the third angle threshold.

[0119] Step S56, the domain controller does not respond to the second opening request. The domain controller does not respond to the second opening request, that is, does not perform the operation of opening the charging port cover.

[0120] The third angle threshold is a small angle threshold, for example, the third angle threshold is between 5 to 10 degrees. In this way, when the battery power is low and needs to be charged, it is ensured that the charging port cover is raised. Even if the battery power does not support opening the charging port cover by the motor, the user can manually open the charging port cover to charge the vehicle.

[0121] In one example, the at least one trigger module comprises a gear switch of the vehicle. The receiving a control request of the charge port cover from any of the trigger modules of the vehicle and controlling the motor of the charge port cover to open or close the charge port cover according to the control request comprises: receiving a fifth control request, and determining whether the charge port cover is in the closed state or in the power feeding up state, and if the charge port cover is in the closed state or in the power feeding up state, not responding to the fifth control request, otherwise, controlling the motor of the charge port cover to close the charge port cover; wherein the fifth control request is triggered when the gear switch is adjusted to the reverse gear.

[0122] In one example, the open angle of the charge port cover and the battery power information provided by the battery management module can be used to determine whether the charge port cover is in the power feeding up state. If the open angle of the charge port cover is less than or equal to a third angle threshold and the battery power is lower than a first power threshold, it can be determined that the charge port cover is in the power feeding up state, otherwise, it is determined that the charge port cover is not in the power feeding up state.

[0123] Referring to Figure 13 As shown, the process of closing the charge port cover when the gear switch is adjusted to the reverse gear comprises steps S61-S66.

[0124] Step S61, the fifth control request is triggered when the gear switch is adjusted to the reverse gear.

[0125] Step S62, the domain controller receives the fifth control request.

[0126] Step S63, the domain controller determines whether the charge port cover is in the closed state through the Hall signal / position switch of the first detection module. If yes, go to step S66. If no, go to step S64.

[0127] Step S64, the domain controller determines whether the charge port cover is in the power feeding up state. If yes, go to step S66. If no, go to step S65.

[0128] Step S65, the domain controller drives the motor to close the charge port cover.

[0129] Step S66, the domain controller does not respond to the fifth control request. The domain controller does not respond to the fifth control request, that is, does not perform the operation of closing the charge port cover.
