Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and in particular to an electric charging port cover control method, system and vehicle. Background Art

[0002] As the number of new energy vehicles continues to increase, more and more new energy vehicles are equipped with electric charging port covers. The electric charging port cover is an important component used to protect the charging interface on new energy vehicles. Its main function is to prevent dust and foreign matter from entering the charging port, affecting the charging effect and the life of the charger. Secondly, the electric charging port cover can prevent the charging port from being accidentally touched by other vehicles or pedestrians, causing damage to the charging port, thereby affecting the charging effect and even causing the charger to malfunction. The electric charging port cover can also prevent the charging port from being accidentally touched by children or pets during the charging process, causing electric shock accidents. Although the electric charging port cover seems simple, its role is very important. It can protect the safety of the charging line and ensure the smooth charging process.

[0003] The electric charging port cover can be opened and closed automatically, which is more convenient and safer than the manual charging port cover. The traditional control methods of the electric charging port cover include press-type, central control soft and hard switch, voice wake-up, etc. The disadvantage of these control methods is that the operation process is relatively cumbersome.

[0004] The emerging electric charging port cover control methods include electric charging port cover control methods based on visual detection and electric charging port cover control methods based on wireless communication of charging piles. The disadvantage of the electric charging port cover control method based on visual detection is that the visual judgment error rate is relatively high, which leads to inaccurate control of the electric charging port cover; the disadvantage of the electric charging port cover control method based on wireless communication of charging piles is that Bluetooth or radio frequency signals are easily interfered and need to match the charging pile, which leads to inaccurate control of the electric charging port cover and cumbersome operation.

[0005] Therefore, how to conveniently and accurately control the electric charging port cover is a technical problem that needs to be solved urgently. Summary of the invention

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions.

[0007] The present invention provides an electric charging port cover control method, comprising the following steps: S1, when the vehicle is in a parking state, if there is a charging pile within a preset range around the current parking position of the vehicle, determining the final parking position of the vehicle, and determining the distance between the current parking position and the final parking position as a reference distance; S2, if the remaining cruising range of the vehicle is less than the reference distance, determining whether anyone in the vehicle has gotten off within a preset detection period; S3: If someone gets off the vehicle within the detection period, open the electric charging port cover of the vehicle.

[0008] Optionally, the method further comprises the following steps: S4: if no charging gun is inserted into the electric charging port cover, determine whether the vehicle meets a preset electric charging port cover closing condition; if the preset electric charging port cover closing condition is met, close the electric charging port cover. Optionally, step S4 includes: If no charging gun is inserted into the electric charging port cover, determining whether the vehicle is in a locked state, or determining whether the current gear position of the vehicle is the P gear, or determining whether the opening time of the electric charging port cover is greater than a preset time threshold; If the vehicle is in a locked state, or the current gear position of the vehicle is not the P gear, or the opening time of the electric charging port cover is greater than a preset time threshold, the electric charging port cover is closed.

[0009] Optionally, the step S1 of determining the final parking position of the vehicle includes: Acquire historical parking data of the vehicle, and determine the final parking position of the vehicle according to the historical parking data.

[0010] Optionally, the acquiring historical parking data of the vehicle includes: Recording the parking position of the vehicle each time it stops within a preset statistical period; A preset statistical number N is used to obtain the most recent N parking positions of the vehicle.

[0011] Optionally, determining the final parking position of the vehicle according to the historical parking data includes: The repeated parking positions and the number of repetitions among the most recent N parking positions of the vehicle are determined, and the parking position with the largest number of repetitions is determined as the terminal parking position of the vehicle.

[0012] Optionally, step S2 includes: determining an average energy consumption of the vehicle; The remaining battery life of the vehicle is determined as the remaining battery life of the vehicle by dividing the remaining battery life of the vehicle by the average energy consumption. If the remaining cruising range of the vehicle is less than the reference distance, it is determined whether anyone has gotten off the vehicle within a preset detection period.

[0013] Optionally, determining the average energy consumption of the vehicle includes: Recording the power consumption per kilometer of the vehicle; The total electric energy consumed by the vehicle in a recent reference distance traveled by the vehicle is determined, and the average energy consumption of the vehicle is calculated based on the total electric energy and the kilometers of the reference distance.

[0014] In addition, the present invention also provides an electric charging port cover control system, comprising: A reference distance determination module, for determining the final parking position of the vehicle when the vehicle is in a parking state, if there is a charging pile within a preset range around the current parking position of the vehicle, and determining the distance between the current parking position and the final parking position as a reference distance; A judgment module, used for judging whether a person has gotten off the vehicle within a preset detection period when the remaining cruising range of the vehicle is less than the reference distance; The electric charging port cover opening module is used to open the electric charging port cover of the vehicle when someone gets off the vehicle within the detection period.

[0015] In addition, the present invention also provides a vehicle, comprising the electric charging port cover control system as described above.

[0016] Through the above technical solution, it is possible to automatically determine whether the electric charging port cover needs to be opened based on the vehicle's current parking position, final parking position, remaining battery life, and whether someone has gotten off the vehicle, which is convenient and quick. The existing technology relies on visual detection or Bluetooth, radio frequency signals to control the electric charging port cover with a relatively high error rate. The data of the current parking position, final parking position, and remaining battery life in this application are relatively accurate, and the result of judging whether someone has gotten off the vehicle is also relatively accurate, thereby making the control of the electric charging port cover more accurate. This application solves the problem of inaccurate control of the electric charging port cover and cumbersome operation in the prior art, thereby achieving the purpose of conveniently and accurately controlling the electric charging port cover.

[0020] The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] The specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0022] Although the various steps in the flowchart in the embodiment of the present invention are shown in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless clearly stated herein, the execution of these steps is not strictly limited in order, and they can be executed in other orders. Moreover, at least a portion of the steps in the figure may include a plurality of sub-steps or a plurality of stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and their execution order is not necessarily carried out in sequence, but can be executed in turn or alternately with other steps or at least a portion of the sub-steps or stages of other steps.

[0023] In the subsequent description, the suffixes such as "module", "device" or "unit" used to represent elements are only used to facilitate the description of the present application, and have no specific meaning. Therefore, "module", "device" or "unit" can be used in a mixed manner.

[0024] Although the terms first, second, third, etc. may be used herein to describe various information, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other.

[0025] See also Figure 1 and Figure 2 According to one aspect of the present application, there is provided a method for controlling an electric charging port cover, comprising the following steps: S1, when the vehicle is in a parking state, if there is a charging pile within a preset range around the current parking position of the vehicle, the final parking position of the vehicle is determined, and the distance between the current parking position and the final parking position is determined as a reference distance.

[0026] The principle of this operation is that if the vehicle is in a parking state and there is a charging pile within a preset range around the current parking position of the vehicle, it can be determined that the purpose of the vehicle parking is to charge. At this time, it is necessary to determine the final parking position of the vehicle and the distance between the current parking position and the final parking position, so as to facilitate further determination of whether the remaining power of the vehicle is sufficient to support the vehicle to travel from the current parking position to the final parking position.

[0027] The location information of the charging piles around the current parking position of the vehicle is all on the network end. The vehicle's navigation system can be used to search whether there are charging piles within the preset range, and the search results are sent to a data processing device that is connected to the navigation system through the navigation system. If there are charging piles, the terminal parking position and reference distance are determined by the data processing device. The data processing device can be, for example, a vehicle control unit (VCU) or other data processing terminals that can be connected to the navigation system, such as a smart phone.

[0028] The vehicle's navigation system is a system that uses the global positioning system (GPS) and electronic map technology to provide accurate navigation services for drivers. Its main functions include locating the vehicle's position, planning the driving route, and providing voice and visual navigation prompts.

[0029] In this embodiment, the data processing device is preferably the VCU of the vehicle. VCU is the core control unit in the new energy vehicle, responsible for monitoring and controlling various functions of the vehicle. The main functions of VCU include collecting the driver's operating intentions, monitoring the vehicle status, and issuing instructions through the controller algorithm to control the driving status of the vehicle. VCU can control the operating mode of the vehicle's power system, power battery system, and on-board accessory power system, and has the function of vehicle system fault diagnosis, protection and storage.

[0030] In this implementation manner, the preset range is preferably within 20 meters from the current parking position.

[0031] S2, if the remaining cruising range of the vehicle is less than the reference distance, determining whether anyone in the vehicle has gotten off within a preset detection period; S3: If someone gets off the vehicle within the detection period, open the electric charging port cover of the vehicle.

[0032] The principle of this operation is that if the remaining range is less than the reference distance, it is determined that the remaining power of the vehicle is insufficient to support the vehicle to travel from the current parking position to the final parking position, and the vehicle needs to be charged. Then it is further determined whether someone gets off the vehicle within the preset detection period. If someone gets off the vehicle, it is determined that the purpose of the person getting off the vehicle is to charge, and the vehicle's electric charging port cover is automatically opened at this time.

[0033] Among them, the data processing device is communicatively connected with the charging system of the vehicle. The charging system of the vehicle refers to a system that provides charging services for the vehicle, and the charging system can provide charging services for the car by connecting to a charging pile. The remaining range of the vehicle can be evaluated by the data processing device, and it can be determined whether the remaining range is less than a reference distance. If the remaining range is less than the reference distance, the data processing device can be used to further determine whether someone has gotten off the vehicle. If someone has gotten off the vehicle, a command to open the electric charging port cover is issued to the charging system of the vehicle through the data processing device to control the charging system to perform the opening operation of the electric charging port cover.

[0034] In this embodiment, it is preferred to determine whether someone has gotten off the vehicle based on the vehicle gear position, door switch information, and seat occupancy signal. Specifically, when the vehicle enters the P gear position, the door is opened, and the seat occupancy signal state of the seat corresponding to the opened door is switched from the occupied state to the unoccupied state, it is determined that someone has gotten off the vehicle. Among them, the doors may include the main driver's door, the front passenger door, and the rear door. The seat corresponding to the main driver's door is the main driver's seat, the seat corresponding to the front passenger door is the front passenger seat, and the seat corresponding to the rear door is the rear seat.

[0035] Among them, the "seat occupancy signal" refers to the signal detected by the vehicle's seat occupancy sensor whether there is a passenger on the seat. The seat occupancy sensor is usually a pressure-sensitive chip installed inside each seat. When a passenger occupies the seat, the seat occupancy signal state is occupied, and when no passenger occupies the seat, the seat occupancy signal state is unoccupied.

[0036] In this embodiment, the detection period is preferably 2 minutes after the vehicle stops.

[0037] The method may further comprise the following steps: S4: if no charging gun is inserted into the electric charging port cover, determine whether the vehicle meets a preset electric charging port cover closing condition; if the preset electric charging port cover closing condition is met, close the electric charging port cover. The principle of this operation is: if there is no charging gun inserted into the electric charging port cover, it can be determined that the vehicle is not charging at this time, and the electric charging port cover needs to be closed to protect the charging port, so it is necessary to further determine whether the vehicle meets the preset electric charging port cover closing conditions. If so, the electric charging port cover is closed.

[0038] Among them, the vehicle's charging system can be used to determine whether a charging gun is inserted into the electric charging port cover, and the charging system can send the judgment result to the vehicle's data processing device. If no charging gun is inserted into the electric charging port cover, the data processing device can be used to further determine whether the vehicle meets the preset electric charging port cover closing conditions. If so, the data processing device can send a command to close the electric charging port cover to the charging system to control the charging system to execute the electric charging port cover closing operation.

[0039] The step S4 may include: If no charging gun is inserted into the electric charging port cover, it is determined whether the vehicle is in a locked state, or whether the current gear position of the vehicle is the P gear, or whether the opening time of the electric charging port cover is greater than a preset time threshold.

[0040] If the vehicle is in a locked state, or the current gear position of the vehicle is not the P gear, or the opening time of the electric charging port cover is greater than a preset time threshold, the electric charging port cover is closed.

[0041] The principle of this operation is: when there is no charging gun inserted into the electric charging port cover, if the vehicle is in a locked state, or the current gear of the vehicle is not P gear, or the opening time of the electric charging port cover is greater than the preset time threshold, it can be judged that the vehicle is not charging or is not ready for charging at this time, and the electric charging port cover needs to be closed to protect the charging port.

[0042] Among them, the vehicle's data processing device can be used to determine whether the vehicle is in a locked state or whether the vehicle's current gear is the P gear; the vehicle's charging system can be used to determine whether the opening time of the electric charging port cover is greater than a preset time threshold, and the judgment result can be sent to the data processing device through the charging system.

[0043] In this implementation, the duration threshold is preferably 2 minutes.

[0044] Determining the final parking position of the vehicle in step S1 may include: Acquire historical parking data of the vehicle, and determine the final parking position of the vehicle according to the historical parking data.

[0045] The principle of this operation is that the parking position with the most repetitions in the historical parking data of the vehicle can usually be determined as the position where the vehicle is most likely to finally park during this trip.

[0046] The historical parking data of the vehicle can be recorded by the navigation system of the vehicle, and the historical parking data can be obtained from the navigation system by the data processing device of the vehicle, and then the terminal parking position can be determined according to the historical parking data by the data processing device.

[0047] In other implementations, the final parking location input by the user may also be received through the human-computer interaction interface of the vehicle.

[0048] The acquiring of the historical parking data of the vehicle may include: The parking position of the vehicle at each stop within a preset statistical time period is recorded.

[0049] A preset statistical number N is used to obtain the most recent N parking positions of the vehicle.

[0050] The vehicle's navigation system may record the parking position of the vehicle each time it stops within a preset statistical period, and the vehicle's data processing device may obtain the vehicle's most recent N parking positions according to a preset statistical number N.

[0051] In this implementation manner, the statistical period is preferably any at least 5 consecutive hours from 21:00 to 9:00 the next day; the statistical number of times N is preferably 7 times.

[0052] Determining the terminal parking position of the vehicle according to the historical parking data may include: The repeated parking positions and the number of repetitions among the most recent N parking positions of the vehicle are determined, and the parking position with the largest number of repetitions is determined as the terminal parking position of the vehicle.

[0053] For example: among the vehicle's most recent 7 parking positions, there are two repeated parking positions, namely the first parking position and the second parking position. The first parking position is repeated 2 times, and the second parking position is repeated 3 times. Then the second parking position is determined as the terminal parking position of the vehicle.

[0054] If the first parking position and the second parking position are repeated three times, the distance between the current parking position of the vehicle and the first parking position is determined as the first distance, and the distance between the current parking position of the vehicle and the second parking position is determined as the second distance.

[0055] If the smaller value of the first distance and the second distance is the first distance, the first parking position is determined as the final parking position of the vehicle; if the smaller value of the first distance and the second distance is the second distance, the second parking position is determined as the final parking position of the vehicle.

[0056] The step S2 may include: An average energy consumption of the vehicle is determined.

[0057] The remaining battery life of the vehicle is determined as the remaining battery life of the vehicle by dividing the average energy consumption.

[0058] If the remaining cruising range of the vehicle is less than the reference distance, it is determined whether anyone has gotten off the vehicle within a preset detection period.

[0059] The data processing device is communicatively connected with the vehicle's power management system, and the remaining power of the vehicle can be obtained from the vehicle's power management system through the data processing device.

[0060] The vehicle's power management system refers to the system responsible for monitoring and managing the vehicle's battery status. The power management system ensures that the battery maintains optimal working condition under various operating conditions, thereby ensuring the vehicle's safety, reliability and endurance. ‌‌

[0061] Determining the average energy consumption of the vehicle may include: The power consumption per kilometer of the vehicle is recorded.

[0062] The total electric energy consumed by the vehicle in a recent reference distance traveled by the vehicle is determined, and the average energy consumption of the vehicle is calculated based on the total electric energy and the kilometers of the reference distance. For example, if the reference distance is 5 kilometers, the total electric energy consumed by the vehicle in the last 5 kilometers is the product of the power consumption per kilometer and 5 kilometers, and the average energy consumption of the vehicle is the result of dividing the total electric energy by 5 kilometers.

[0063] The present application calculates the average energy consumption of the vehicle based on the total electric energy consumed by the vehicle in the most recent reference distance it has traveled, and can obtain an average energy consumption that is more accurate, reliable, and closer to the current state of the vehicle.

[0064] Through the above technical solution, it is possible to automatically determine whether the electric charging port cover needs to be opened based on the vehicle's current parking position, final parking position, remaining battery life, and whether someone has gotten off the vehicle, which is convenient and quick. The existing technology relies on visual detection or Bluetooth, radio frequency signals to control the electric charging port cover with a relatively high error rate. The data of the current parking position, final parking position, and remaining battery life in this application are relatively accurate, and the result of judging whether someone has gotten off the vehicle is also relatively accurate, thereby making the control of the electric charging port cover more accurate. This application solves the problem of inaccurate control of the electric charging port cover and cumbersome operation in the prior art, thereby achieving the purpose of conveniently and accurately controlling the electric charging port cover. See also Figure 3 Another aspect of the present application provides an electric charging port cover control system, including: The reference distance determination module 1 is used to determine the final parking position of the vehicle when the vehicle is in a parking state, if there is a charging pile within a preset range around the current parking position of the vehicle, and determine the distance between the current parking position and the final parking position as the reference distance.

[0065] The judgment module 2 is used to judge whether someone has gotten off the vehicle within a preset detection period when the remaining cruising range of the vehicle is less than the reference distance.

[0066] The electric charging port cover opening module 3 is used to open the electric charging port cover of the vehicle when someone gets off the vehicle within the detection period.

[0067] The system may also include the following modules: The electric charging port cover closing module is communicatively connected to the vehicle's charging system and is used to determine whether the vehicle is in a locked state, or whether the current gear position of the vehicle is the P gear, or whether the opening time of the electric charging port cover is greater than a preset time threshold when no charging gun is inserted into the electric charging port cover; if the vehicle is in a locked state, or the current gear position of the vehicle is not the P gear, or the opening time of the electric charging port cover is greater than the preset time threshold, the electric charging port cover is closed.
