Description

Technical Field

[0001] This invention belongs to the field of vehicle control technology, and particularly relates to a control method, device and vehicle for a vehicle charging port cover. Background Technology

[0002] With the development of the automotive industry, users' demands for vehicle convenience, comfort, and technological sophistication are gradually increasing. In particular, the rapid development of electric vehicles has led to more and more users coming into contact with the charging port cover. Compared with gasoline vehicles, users have a more profound experience with the charging port cover than with the fuel filler cap, because the fuel filler cap is usually opened and closed by gas station staff, while the charging port cover is mostly opened and closed by the user.

[0003] For the reasons mentioned above, some high-end models have begun to equip their vehicles with electric charging port covers. Currently, these electric charging port covers can automatically open upon receiving an open command, automatically close upon receiving a close command, and stop when encountering obstacles. However, the level of intelligence in the control of the charging port covers is relatively low. Summary of the Invention

[0004] This invention provides a method, device, and vehicle for controlling a vehicle charging port cover, thereby improving the intelligence level of the charging port cover control.

[0005] In a first aspect, embodiments of the present invention provide a method for controlling a vehicle charging port cover, comprising: acquiring vehicle control information, the vehicle control information including at least vehicle status information, the vehicle status information including opening degree change parameters of the charging port cover; if there is no user instruction information in the vehicle control information, and the opening degree change parameters are within a preset opening degree change range, generating a charging port cover control command based on the opening degree change parameters; and controlling the opening and closing of the charging port cover according to the charging port cover control command.

[0006] In conjunction with the first aspect of the present invention, in some embodiments, the opening degree change parameter characterizes the change of the current opening degree of the charging port cover relative to the last stopped opening degree, and the step of generating a charging port cover control command based on the opening degree change parameter includes: if the current opening degree is closer to the fully open opening degree of the charging port cover than the last stopped opening degree, generating a charging port cover control command for opening the charging port cover; if the current opening degree is closer to the fully closed opening degree of the charging port cover than the last stopped opening degree, generating a charging port cover control command for closing the charging port cover.

[0007] In conjunction with the first aspect of the present invention, in some embodiments, the vehicle status information further includes the vehicle's gear position status, and the method further includes: if there is no user instruction information in the vehicle control information, the opening degree change parameter is less than the lower limit value within the opening degree change range, and the gear position status indicates that the vehicle has changed from a stationary state to a driving state, then a charging port cover control command for closing the charging port cover is generated.

[0008] In conjunction with the first aspect of the present invention, in some embodiments, the vehicle status information further includes the vehicle's charging status, and the method further includes: if user instruction information exists in the vehicle control information; if the user instruction information is used to instruct the opening of the charging port cover, and the gear position indicates that the vehicle is currently in the stationary state, generating a charging port cover control command for opening the charging port cover; if the user instruction information is used to instruct the closing of the charging port cover, and the charging status indicates that the charging gun has been disconnected from the charging port, generating a charging port cover control command for closing the charging port cover.

[0009] In conjunction with the first aspect of the present invention, in some embodiments, controlling the opening and closing of the charging port cover according to the charging port cover control command includes: if the charging port cover control command is a command for opening the charging port cover, driving the charging port cover to perform an opening action via a motor, monitoring the motor status when the charging port cover is not fully open, and determining whether to stop the opening action based on the motor status; if the charging port cover control command is a command for closing the charging port cover, driving the charging port cover to perform a closing action via a motor, monitoring the motor status when the charging port cover is not fully closed, and determining whether to stop the closing action based on the motor status.

[0010] In conjunction with the first aspect of the present invention, in some embodiments, the motor state includes motor operating time and motor current, and the step of determining whether to stop the opening action based on the motor state includes: monitoring motor operating time and motor current; recording an opening failure each time the motor operating time exceeds a first operating time threshold or the motor current exceeds a first current threshold; and controlling the motor to stop if the number of opening failures of the charging port cover exceeds the first threshold.

[0011] In conjunction with the first aspect of the present invention, in some embodiments, the motor state includes motor operating time and motor current, and the step of determining whether to stop the closing action based on the motor state includes: monitoring the motor operating time and motor current; recording a closing failure each time the motor operating time exceeds a second operating time threshold or the motor current exceeds a second current threshold; and controlling the motor to stop if the number of closing failures of the charging port cover exceeds a second threshold.

[0012] In conjunction with the first aspect of the present invention, in some embodiments, after the motor is stopped, the method includes: obtaining the current opening degree of the charging port cover as the last stopping opening degree.

[0013] Secondly, embodiments of the present invention provide a control device for a vehicle charging port cover, comprising: an information acquisition unit for acquiring vehicle control information, the vehicle control information including at least vehicle status information, the vehicle status information including opening degree change parameters of the charging port cover; a first instruction generation unit for generating a charging port cover control instruction based on the opening degree change parameters if there is no user instruction information in the vehicle control information and the opening degree change parameters are within a preset opening degree change range; and an instruction execution unit for controlling the opening and closing of the charging port cover according to the charging port cover control instruction.

[0014] Thirdly, embodiments of the present invention provide a vehicle, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the method described in any of the first aspects.

[0015] The one or more technical solutions provided in the embodiments of the present invention achieve at least the following technical effects or advantages:

[0016] This invention acquires vehicle control information, including at least vehicle status information, which includes parameters for the opening change of the charging port cover. If no user instruction is present in the vehicle control information, and the opening change parameters are within a preset range, a charging port cover control command is generated based on the opening change parameters. The charging port cover is then controlled to open and close according to the control command. By using the opening change parameters, the user's intended direction of operation on the charging port cover can be determined. This allows the generation of a charging port cover control command to automatically move the charging port cover in the user's direction of operation, achieving accurate recognition of the user's intention and thus improving the intelligence level of the charging port cover control.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0024] This invention provides a method for controlling a vehicle charging port cover, see reference. Figure 1 As shown, the method includes the following steps:

[0025] S101: Obtain vehicle control information, which includes at least vehicle status information, including parameters related to the opening change of the charging port cover.

[0026] It should be noted that vehicle control information refers to information used to control the charging port cover. The opening change parameter characterizes the change in the current opening degree of the charging port cover relative to the last stopped opening degree. Specifically, the opening change parameter can be the absolute value of the difference between the current opening degree and the last stopped opening degree.

[0027] It should be noted that the vehicle status information also includes the vehicle's gear position and charging status.

[0028] S102: If there is no user instruction information in the vehicle control information and the opening change parameter is within the preset opening change range, generate a charging port cover control command based on the opening change parameter.

[0029] Understandably, if there is no user instruction information in the vehicle control information and the opening change parameter is not within the preset opening change range, the process will end.

[0030] It should be noted that the user instruction information includes information for instructing the opening of the charging port cover and information for instructing the closing of the charging port cover. The range of opening degree variation can be no less than 1 degree.

[0031] It is understandable that the method for obtaining information on whether the opening change parameter is within the preset opening change range may include the following steps Y1 to Y3:

[0032] Step Y1: Obtain the absolute value of the difference between the current opening degree and the last stopped opening degree, and use it as the opening degree change parameter.

[0033] Step Y2: If the opening change parameter is not less than 1 degree, determine that the opening change parameter is within the preset opening change range.

[0034] Step Y3: If the opening change parameter is less than 1 degree, it is determined that the opening change parameter is not within the preset opening change range, and the process ends.

[0035] It is understandable that generating charging port cover control instructions based on opening change parameters means obtaining the relationship between the current opening degree and the last stopped opening degree, and determining the charging port cover control instructions based on the opening degree relationship.

[0036] It is understandable that the method for generating charging port cover control commands based on opening change parameters includes the following steps A1 to A2:

[0037] A1: If the current opening degree is closer to the fully open opening degree of the charging port cover than the last stopped opening degree, generate a charging port cover control command to open the charging port cover.

[0038] Specifically, the opening degree that is closer to the charging port cover being fully open than the last time the opening degree was stopped can be the current opening angle being greater than the last time the opening degree was stopped.

[0039] It should be noted that the previous stopping opening degree could be the recorded stopping opening degree when the charging port cover stopped rotating due to an obstacle. Therefore, the reason why the current opening degree is closer to the fully open charging port cover than the previous stopping opening degree could be that after the charging port cover stopped rotating and the user cleared the obstacle, the user operated the charging port cover to open it, making the current opening degree closer to the fully open charging port cover. At this time, a charging port cover control command is generated to open the charging port cover.

[0040] A2: If the current opening degree is closer to the fully closed opening degree of the charging port cover than the last stopped opening degree, generate a charging port cover control command to close the charging port cover.

[0041] Specifically, the opening degree that is closer to the charging port cover being fully closed than the last closing opening degree can be the current opening angle being smaller than the last closing opening angle.

[0042] It should be noted that the reason why the current opening degree is closer to the fully closed charging port cover than the last closing opening degree could be that after the charging port cover stops rotating and the user clears the obstruction, the user operates the charging port cover to close it, making the current opening degree closer to the fully closed charging port cover. At this time, a charging port cover control command is generated to close the charging port cover.

[0043] It should be noted that if the opening change parameter falls within the preset opening change range, it may be because the charging port cover encountered an obstacle, stopped, and after the obstacle was cleared, the user's operation caused the charging port cover to move. However, it cannot accurately identify whether the user intends to close or open the charging port cover. In this case, steps A1 to A2 in S102 compare the current opening with the last stopped opening to determine whether the user intends to close or open the charging port cover. Therefore, it can accurately identify the user's operation intention and improve the intelligence level of the charging port cover control.

[0044] It should be noted that, in addition to step S102 generating the charging port cover control command, the process also includes the following steps S1021 to S1023:

[0045] S1021: If there is no user instruction information in the vehicle control information, the opening change parameter is less than the lower limit value within the opening change range, and the gear status indicates that the vehicle has changed from a stationary state to a driving state, then a charging port cover control command for closing the charging port cover is generated.

[0046] It is understandable that the method for obtaining information representing the change of a vehicle's gear position from a stationary state to a moving state may include steps B1 and B2:

[0047] B1: Determine if the gear position has changed. If the gear position has changed, proceed to step B2; otherwise, terminate the process.

[0048] B2: If the vehicle changes from P to D, the gear position indicates that the vehicle has changed from a stationary state to a moving state.

[0049] It should be noted that the reason why the opening change parameter is less than the lower limit of the opening change range could be that the opening of the charging port cover has not changed, that is, the user has not moved the charging port cover. The gear position indicates that the vehicle has changed from a stationary state to a driving state, such as changing the vehicle from P gear to D gear.

[0050] It should be noted that when the vehicle changes from a stationary state to a driving state, there may be a situation where the vehicle has finished charging and has started driving, but the charging port cover is forgotten to be closed. In response to this situation, step S1021 can generate a charging port cover control command to close the charging port cover, thereby protecting the charging port cover and improving the intelligence level of the charging port cover control.

[0051] S1022: If user instruction information exists in the vehicle control information; if the user instruction information is used to instruct the opening of the charging port cover, and the gear position indicates that the vehicle is currently stationary, generate a charging port cover control command for opening the charging port cover.

[0052] It is understandable that, when the gear position does not indicate that the vehicle is currently stationary, the following steps C1 to C3 are also included:

[0053] C1: Reminds the user to shift to P gear and wait for a period of time.

[0054] C2: Determines if the gear is P (Park).

[0055] C3: If the gear is P, generate a charging port cover control command to open the charging port cover. Otherwise, terminate the process.

[0056] It should be noted that directly generating a charging port cover control command after the user provides information instructing the user to open the cover could potentially lead to damage if the user incorrectly provides the wrong instruction while the vehicle is in motion. To address this, step S1022 incorporates a gear position determination to prevent the charging port cover from opening while the vehicle is in motion, thus improving the safety of opening the cover and enhancing the intelligence of the charging port cover control.

[0057] S1023: If user instruction information exists in the vehicle control information; if the user instruction information is used to instruct the charging port cover to be closed, and the charging status indicates that the charging gun has been disconnected from the charging port, a charging port cover control command is generated to close the charging port cover.

[0058] It is understandable that, if the charging status does not indicate that the charging gun has been disconnected from the charging port, the following steps D1 to D3 are also included:

[0059] D1: Reminds the user to disconnect the charging gun from the charging port and wait for a period of time.

[0060] D2: Determine whether the charging gun is disconnected from the charging port.

[0061] D3: If the charging gun is disconnected from the charging port, generate a charging port cover control command to close the charging port cover. Otherwise, terminate the process.

[0062] It should be noted that directly generating a control command to close the charging port cover after the user provides the information to instruct it to close may cause problems if the charging gun is not detached from the charging port and the user incorrectly provides the instruction, resulting in the charging port cover closing and potentially damaging it. To address this, step S1023 introduces a charging status check to prevent the charging port cover from closing while the charging gun is still in the charging port. This reduces the number of times the motor triggers its anti-collision and anti-pinch mechanisms, extends the motor's lifespan, and improves the intelligence of the charging port cover control.

[0063] S103: Controls the opening and closing of the charging port cover according to the charging port cover control command.

[0064] It is understandable that, according to the charging port cover control command, the method for controlling the opening and closing of the charging port cover includes the following steps S1031~S1032:

[0065] S1031: If the charging port cover control command is for opening the charging port cover, the charging port cover is driven by the motor to perform the opening action. If the charging port cover is not fully open, the motor status is monitored, and the opening action is stopped based on the motor status.

[0066] It is understandable that using a motor to drive the charging port cover to open means controlling the motor to start and rotate forward so that the charging port cover opens when it is not fully open. Specifically, using a motor to drive the charging port cover to open includes the following steps E1 to E3:

[0067] E1: Determine if the charging port cover is fully open. If the charging port cover is not fully open, proceed to step E2; if the charging port cover is fully open, terminate the process.

[0068] E2: Determine if the motor has started. If it has not started, start the motor in the forward direction and return to step E2; if it has started, proceed to step E3.

[0069] E3: Determine if the motor is rotating in the forward direction. If it is, proceed to step E4; otherwise, stop the motor, wait for a certain period of time, then start the motor in the forward direction and return to step E2.

[0070] It should be noted that step E4 involves determining whether to stop the starting action based on the motor's status. The motor status includes the motor's running time and current. Specifically, determining whether to stop the starting action based on the motor's status includes the following steps F1 to F4:

[0071] F1: Determine if the charging port cover is fully open. If the charging port cover is fully open, stop the motor and end the process. If the charging port cover is not fully open, proceed to step F2.

[0072] F2: Monitors motor running time and motor current.

[0073] F3: If the motor running time exceeds the first running time threshold or the motor current exceeds the first current threshold, record an start-up failure. Otherwise, return to step F1.

[0074] F4: If the number of failed attempts to open the charging port cover exceeds the threshold for the first attempt, control the motor to stop, output a user prompt message to indicate the failure to open, and obtain the current opening degree of the charging port cover as the last stopping opening degree; otherwise, return to step F1.

[0075] S1032: If the charging port cover control command is for closing the charging port cover, the charging port cover is driven by the motor to perform the closing action. If the charging port cover is not fully closed, the motor status is monitored, and the closing action is stopped based on the motor status.

[0076] It is understandable that using a motor to drive the charging port cover to perform the closing action means controlling the motor to start and reverse so that the charging port cover closes when it is not fully closed. Specifically, using a motor to drive the charging port cover to perform the closing action includes the following steps G1 to G3:

[0077] G1: Determine if the charging port cover is fully closed. If the charging port cover is not fully closed, proceed to step G2; if the charging port cover is fully closed, terminate the process.

[0078] G2: Determine if the motor has started. If it has not started, start the motor in reverse and return to step G2. If it has started, execute step G3.

[0079] G3: Determine if the motor rotation direction is reversed. If it is reversed, proceed to step G4; if it is not reversed, stop the motor, wait for a certain period of time, then start the motor in reverse and return to step G2.

[0080] It should be noted that step G4 is the process of determining whether to stop the shutdown action based on the motor status. Specifically, determining whether to stop the shutdown action based on the motor status includes the following steps H1 to H4:

[0081] H1: Determine if the charging port cover is fully closed. If the charging port cover is fully closed, stop the motor and end the process. If the charging port cover is not fully closed, proceed to step H2.

[0082] H2: Monitor motor running time and motor current.

[0083] H3: If the motor running time exceeds the second running time threshold or the motor current exceeds the second current threshold, record a shutdown failure. Otherwise, return to step H1.

[0084] H4: If the number of times the charging port cover fails to close exceeds the second threshold, control the motor to stop, output a user prompt message to indicate that the closing has failed, and obtain the current opening degree of the charging port cover as the last stopping opening degree; otherwise, return to step H1.

[0085] It should be noted that the first operating time threshold can be 2 seconds, the second operating time threshold can be 2 seconds, the first current threshold can be 300mA, the second current threshold can be 300mA, the first count threshold can be 2 times, and the second count threshold can be 2 times.

[0086] It should be noted that when the charging port cover encounters an obstacle, the motor running time will increase and the motor current will increase. Therefore, monitoring the motor running time and motor current in steps S1031 and S1032 is to prevent the opening and closing actions from continuing when the charging port cover encounters an obstacle. This can achieve the effect of protecting the motor and improve the intelligence level of the charging port cover control.

[0087] To enhance understanding of the generation of charging port cover control commands in the embodiments of the present invention, refer to Figure 2 As shown, steps S102, S1021, S1022, and S1023 will be combined and illustrated below:

[0088] Step 1: When the user indicates that the charging port cover should be opened, determine whether to generate a charging port cover control command for opening the charging port cover based on the gear position.

[0089] Step 2: When the user indicates that the charging port cover should be closed, determine whether to generate a charging port cover control command to close the charging port cover based on the charging status.

[0090] Step 3: When there is no user instruction information in the vehicle control information and the opening change parameter is within the preset opening change range, generate a charging port cover control command based on the opening change parameter.

[0091] Step 4: When there is no user instruction information in the vehicle control information, the opening change parameter is less than the lower limit of the opening change range, and the gear status indicates that the vehicle has changed from a stationary state to a driving state, a charging port cover control command is generated to close the charging port cover.

[0092] This invention acquires vehicle control information, including at least vehicle status information, which includes parameters for the opening change of the charging port cover. If no user instruction is present in the vehicle control information, and the opening change parameters are within a preset range, a charging port cover control command is generated based on the opening change parameters. The charging port cover is then controlled to open and close according to the control command. By using the opening change parameters, the user's intended direction of operation on the charging port cover can be determined. This allows the generation of a charging port cover control command to automatically move the charging port cover in the user's direction of operation, achieving accurate recognition of the user's intention and thus improving the intelligence level of the charging port cover control.

[0093] Based on the same inventive concept, and referring to Figure 3 As shown, this embodiment of the invention provides a control device 10 for a vehicle charging port cover, comprising: an information acquisition unit 110, used to acquire vehicle control information, the vehicle control information including at least vehicle status information, the vehicle status information including opening degree change parameters of the charging port cover; a first instruction generation unit 120, used to generate a charging port cover control instruction based on the opening degree change parameters if there is no user instruction information in the vehicle control information and the opening degree change parameters are within a preset opening degree change range; and an instruction execution unit 130, used to control the opening and closing of the charging port cover according to the charging port cover control instruction.

[0094] Understandably, the opening change parameter represents the change in the current opening of the charging port cover relative to the last stopped opening. The first instruction generation unit 120 is specifically used to: generate a charging port cover control instruction for opening the charging port cover if the current opening is closer to the fully open opening of the charging port cover than the last stopped opening; and generate a charging port cover control instruction for closing the charging port cover if the current opening is closer to the fully closed opening of the charging port cover than the last stopped opening.

[0095] It is understandable that the vehicle status information also includes the vehicle's gear position status. The vehicle charging port cover control device 10 also includes: a second instruction generation unit 140, which generates a charging port cover control instruction to close the charging port cover if there is no user instruction information in the vehicle control information, the opening change parameter is less than the lower limit value within the opening change range, and the gear position status indicates that the vehicle has changed from a stationary state to a driving state.

[0096] Understandably, the vehicle status information also includes the vehicle's charging status. The vehicle charging port cover control device 10 further includes: a third instruction generation unit 150, used to generate a charging port cover control instruction for opening the charging port cover if user instruction information exists in the vehicle control information; if the user instruction information is used to instruct the opening of the charging port cover, and the gear position indicates that the vehicle is currently stationary; and if the user instruction information is used to instruct the closing of the charging port cover, and the charging status indicates that the charging gun has been disconnected from the charging port, generate a charging port cover control instruction for closing the charging port cover.

[0097] It is understood that the instruction execution unit 130 includes: an opening execution subunit 1301, used to drive the charging port cover to perform an opening action by means of a motor if the charging port cover control instruction is for opening the charging port cover, monitor the motor status if the charging port cover is not fully open, and determine whether to stop the opening action based on the motor status; and a closing execution subunit 1302, used to drive the charging port cover to perform a closing action by means of a motor if the charging port cover control instruction is for closing the charging port cover, monitor the motor status if the charging port cover is not fully closed, and determine whether to stop the closing action based on the motor status.

[0098] Understandably, the motor status includes motor running time and motor current. The execution subunit 1301 is activated to specifically monitor the motor running time and motor current; record an opening failure each time the motor running time exceeds the first running time threshold or the motor current exceeds the first current threshold; if the number of opening failures of the charging port cover exceeds the first threshold, control the motor to stop.

[0099] Understandably, the motor status includes motor running time and motor current. The shutdown execution subunit 1302 is specifically used to: monitor motor running time and motor current; record a shutdown failure each time the motor running time exceeds the second running time threshold or the motor current exceeds the second current threshold; if the number of shutdown failures of the charging port cover exceeds the second threshold, control the motor to stop.

[0100] It is understandable that the vehicle charging port cover control device 10 also includes: a stop opening degree acquisition unit 160, which is used to acquire the current opening degree of the charging port cover after the control motor stops, as the last stop opening degree.

[0101] It should be understood that further implementation details of the vehicle charging port cover control device 10 in the embodiments of the present invention are described in the aforementioned vehicle charging port cover control method, and will not be repeated here for the sake of brevity.

[0102] Based on the same inventive concept, embodiments of the present invention also provide a vehicle, such as Figure 4As shown, it includes a memory 404, a processor 402, and a computer program stored in the memory 404 and executable on the processor 402. The processor 402 executes the program to implement the steps described in any embodiment of the vehicle charging port cover control method.

[0103] Among them, Figure 4 In this document, a bus architecture (represented by bus 400) is used. Bus 400 may include any number of interconnected buses and bridges, linking various circuits including one or more processors represented by processor 402 and memory represented by memory 404. Bus 400 may also link various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further herein. Bus interface 405 provides an interface between bus 400 and receiver 401 and transmitter 403. Receiver 401 and transmitter 403 may be the same element, i.e., a transceiver, providing a unit for communicating with various other devices over a transmission medium. Processor 402 is responsible for managing bus 400 and general processing, while memory 404 can be used to store data used by processor 402 during operation.

[0104] This invention can determine the user's intention to operate the charging port cover by changing the opening parameter. Then, it generates a charging port cover control command to control the opening and closing of the charging port cover, so that the charging port cover automatically moves in the direction of the user's operation. This achieves the effect of accurately recognizing the user's operation intention, thereby improving the intelligence level of the charging port cover control.

[0105] The functions described herein can be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, the functions can be stored as one or more instructions or codes on or transmitted via a computer-readable medium. Other examples and embodiments are within the scope and spirit of this invention and the appended claims. For example, due to the nature of software, the functions described above can be implemented using software executed by a processor, hardware, firmware, hardwired, or any combination thereof. Furthermore, the functional units can be integrated into a single processing unit, or each unit can exist physically separately, or two or more units can be integrated into a single unit.

[0106] In the several embodiments provided in this application, it should be understood that the disclosed technical content can be implemented in other ways. The device embodiments described above are merely illustrative; for example, the division of units can be a logical functional division, and in actual implementation, there may be other division methods. For instance, multiple units or components may be combined or integrated into another system, or some features may be ignored or not executed. Furthermore, the displayed or discussed mutual coupling, direct coupling, or communication connection may be through some interfaces; the indirect coupling or communication connection between units or modules may be electrical or other forms.

[0107] The units described as separate components may or may not be physically separate.
