[0038] The following description, in conjunction with the accompanying drawings, illustrates exemplary embodiments of the present invention, including various details to aid understanding. These details should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the invention. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0039] It should be noted that, unless otherwise specified, the embodiments of the present invention and the technical features thereof can be combined with each other.

[0040] Furthermore, the terms "first," "second," and "third," etc., included in the terminology of this invention are used to distinguish similar objects and are not necessarily used to describe a specific number or order. It should be understood that such terms can be used interchangeably where appropriate; this is merely a distinguishing method used in the embodiments of this invention when describing objects with the same attributes.

[0041] Furthermore, the vehicles involved in the embodiments of the present invention may be internal combustion engine vehicles that use an engine as a power source, hybrid vehicles that use an engine and an electric motor as power sources, electric vehicles that use an electric motor as a power source, etc.

[0042] Figure 1 This is a schematic diagram illustrating the main steps of a vehicle data transmission method according to an embodiment of the present invention. Figure 1 As shown, the method for transmitting vehicle data mainly includes the following steps:

[0043] Step S101: Determine the power type based on the charging gun interface on the target charging station;

[0044] Step S102: Receive the mode selection instruction sent by the user;

[0045] Step S103: When the mode selection command indicates that the selected mode is the first mode, determine the first interface on the charging gun interface for data transmission according to the power type; the first mode indicates that data transmission is performed while charging.

[0046] Step S104: Use the first interface to transmit data with the target charging pile.

[0047] In the actual charging process of vehicles using charging stations, different power types can be used. Naturally, the selected charging gun and the charging gun interface configured on the charging gun will also be different. In one optional embodiment, the power type can include DC power or AC power. When using AC power to charge electric vehicles, the power is generally lower, which is also known as slow charging; while when using DC power to charge electric vehicles, it refers to the charging equipment rectifying the AC power from the grid before inputting it into the vehicle. The charging power can include 20KW, 40KW, 60KW up to 200KW, 250KW, 350KW, etc., as long as the input end (grid) and the output end (vehicle) support the charging power, which is also known as fast charging.

[0048] In existing technologies, charging stations only provide charging functionality for electric vehicles. Therefore, they do not need to receive user mode selection commands, and there is no first mode in this embodiment of the invention, which simply involves inserting the charging gun interface on the charging gun into the charging interface on the vehicle to achieve charging. However, in this embodiment of the invention, user mode selection is required. In one optional embodiment, this mode selection command can be input from either the vehicle or the charging station.

[0049] When a mode selection command is input from the vehicle, in one optional embodiment, the process can be performed after step S101 and before step S102, specifically including: sending a prompt message to the user via a pop-up window displayed on the in-vehicle screen or through voice broadcast to prompt the user to select a mode. For example, a mode selection dialog box can pop up on the in-vehicle screen, displaying multiple selectable modes, such as a first mode (data transmission while charging), a second mode (charging only), etc., and the user's mode selection command is determined in response to the user's touch feedback. Similarly, when a selection command is input from the charging pile, a pop-up window or dialog box can be displayed on the screen of the charging pile for the user to select. It is worth noting that after the user receives the mode selection command through the charging pile, the mode selection command needs to be sent to the vehicle control system via near-field communication and / or wireless communication, so that the vehicle can adjust the first interface according to the mode selection command to complete the subsequent data transmission process. In a further optional embodiment, when there are multiple prompting methods for mode selection, the mode selection instruction sent by the user in step S102 can also be received in multiple ways, specifically including: receiving the mode selection instruction sent by the user by performing one or more of the following methods on the touch information received by the vehicle screen: touch recognition, voice recognition, and gesture recognition.

[0050] To ensure the security of charging and data transmission, the target charging pile in this embodiment of the invention refers to a charging pile that has been matched with the vehicle. This matching process verifies and pairs the vehicle information with the charging pile, ensuring the safety of the vehicle during charging. For home charging piles, there is a matching relationship between the charging pile and the vehicle; that is, when a home charging pile is purchased, it is bound to the vehicle information belonging to the current household. Therefore, when charging the vehicle, the target charging pile can be used directly for charging or data transmission.

[0051] For public charging stations, direct charging or data transmission is usually not possible. Therefore, in the process of determining the power type in step S101, one optional embodiment is as follows: Figure 2 As shown, it includes:

[0052] Step S201: Using near-field communication and / or wireless communication, determine the target charging pile that matches the vehicle from one or more unmatched charging piles within the vehicle's preset range, and monitor each charging gun on the target charging pile in real time.

[0053] Step S202: When the target charging gun is detected to be unplugged from the target charging station, the power type is determined according to the charging gun interface corresponding to the target charging gun.

[0054] Near Field Communication (NFC) is a technology that allows devices (such as mobile phones) to exchange data when they are close to each other. It evolved from contactless Radio Frequency Identification (RFID) and interconnection technologies. Wireless communication, also known as wireless local area network (WLAN) communication, is a communication method that utilizes the ability of electromagnetic waves to propagate in free space for information exchange. A wireless communication system mainly consists of the following components: information, transceiver, transmitter, channel, and receiver. Specific technologies include Wi-Fi, Bluetooth, and ZigBee, used for wireless communication within a local area network. It is understandable that other technologies, such as satellite communication, infrared communication, and fiber optic communication, can be chosen for communication between vehicles and charging stations.

[0055] Specifically, when a user uses a public charging station, there are usually multiple public charging stations in the garage, so the user needs to select one to determine the unique target charging station to use. That is, the process of determining the target charging station in step S201 can be as follows: Figure 3 As shown, it further includes:

[0056] Step S301: When there is no matching charging pile within the vehicle's preset range, obtain one or more unmatched charging piles;

[0057] Step S302: In response to the user's charging pile selection command, determine the charging pile to be used;

[0058] Step S303: Send a matching request to the charging station to be used;

[0059] Step S304: Receive the matching result from the charging pile to be used in response to the matching request. If the matching result indicates that the matching is successful, use the charging pile to be used as the target charging pile.

[0060] By following the steps described above, the target charging station can be identified from multiple unmatched charging stations. After identifying the target charging station, step S202 monitors whether the charging gun in the target charging station is unplugged. It should be noted that if the matching result indicates a matching failure, it means that the vehicle cannot be matched with the target charging station and needs to be matched again or with other unmatched charging stations.

[0061] The charging gun interfaces differ depending on the power type. Therefore, by unplugging the target charging gun, it's possible to determine the user's intended power type. Specifically, the charging gun interfaces corresponding to different power types can be as follows: Figure 4 and Figure 5 As shown, where, Figure 4 The AC power charging gun interface is shown, specifically including the L1, L2, and L3 interfaces corresponding to the three phases, the neutral line interface (N), the charging connection confirmation interface (CC), and the control guidance interface (CP). Figure 5 The diagram illustrates a DC power supply charging gun interface, specifically including the power supply's positive and negative terminals (DC+ and DC-), device ground (PE), charging communication interfaces (S+ and S-), charging connection confirmation interfaces (CC1 and CC2), and auxiliary light source interfaces (A+ and A-). This invention improves upon existing charging gun interfaces by addressing less frequently used interfaces during charging, enabling synchronous data transmission during the charging process.

[0062] The specific improvement process is described in detail below. In one optional embodiment, after the mode selection instruction indicates that the selected mode is the first mode, and after determining the first interface for data transmission on the charging gun interface according to the power type, the method further includes: using a relay installed inside the vehicle to adjust the power supply circuit connected to the first interface from the first circuit to the second circuit; wherein the voltage of the second circuit is lower than the voltage of the first circuit. In other words, by setting a relay, the present invention can automatically adjust the power supply circuit of the first interface after the user selects the first mode, so that after the user inserts the charging gun interface into the vehicle interface, data transmission can be performed using the interface that was originally unable to transmit data.

[0063] Specifically, step S103, which determines the first interface based on the power supply type, includes: when the power supply type is AC, using the L2 and L3 terminals of the three-phase charging gun interface as the first interface; or when the power supply type is DC, using the A+ and A- terminals of the charging gun interface as the first interface. With the continuous development of charging technology, in existing AC three-phase interfaces, only L1 is needed to achieve a 220V charging effect. Therefore, this invention selects the L2 and L3 terminals as the first interface for data transmission during vehicle charging. In DC power, the A+ and A- terminals are usually used as auxiliary light sources to charge the vehicle's internal battery when the vehicle is awakened. Therefore, during charging at the charging station, these terminals are idle. Thus, this invention selects the A+ and A- terminals as the first interface for data transmission when charging with AC power. It can be seen that this invention selects different interfaces as the first interface for different power supply types and uses relays to adjust the circuit connected to the interfaces, achieving the purpose of data transmission. Specifically, the modified first interfaces for different power supply types are as follows: Figure 6 and Figure 7 As shown, where, Figure 6 This is a schematic diagram of the improved power interface for AC power. Figure 7 This is a schematic diagram of the improved power interface for a DC power supply. Figure 6 As can be seen, the original L2 and L3 interfaces become CAN_H and CAN_L interfaces after the relay is connected. Figure 7 As can be seen, the original A+ and A- interfaces become CAN_H and CAN_L interfaces after the relays are connected, with the relays connected to one end of the vehicle socket. In a further optional embodiment, the second loop is a CAN channel, which can use the CAN2.0 / CANFD protocol or other communication protocols that meet the communication requirements. When the power supply type is AC, the first loop is a loop composed of L2 and L3 interfaces; when the power supply type is DC, the first loop is a loop composed of A+ and A- interfaces.

[0064] Furthermore, data transmission typically requires low voltage, thus imposing strict requirements on the voltages of the first and second circuits. In one optional embodiment, the voltage of the second circuit is 0-4V; when the power supply type is DC, the voltage of the first circuit is 12-18V; when the power supply type is AC, the voltage of the first circuit is 220V or 110V. In other words, a relay can be used to adjust the high voltage to a low voltage under different power supply types, thereby meeting the voltage requirements for data transmission.

[0065] Understandably, after the user selects the first mode, the relay automatically adjusts the circuit. Therefore, after charging is complete, the relay can also restore the circuit. That is, after data transmission via the charging pile using the first interface, the system further includes: when the target charging gun is detected being inserted into the target charging pile, the relay restores the power circuit connected to the first interface from the second circuit back to the first circuit. This way, the original interface function is not affected after charging; only the data transmission interface is used during charging, improving interface efficiency. Simultaneously, no significant structural adjustments to the charging gun interface are required, saving on modification costs.

[0066] In one optional embodiment, the transmitted data may include one or more of software updates, photo transfers, and music transfers. It is understood that before data transmission, a confirmation message can be sent to the user for confirmation before data transmission, or data transmission can be performed automatically. For example, before transferring photos or music, the user can be asked to confirm whether data transmission is necessary and to select the specific data content to be transmitted. During software updates, no confirmation message needs to be sent to the user; the update can proceed automatically to improve software synchronization. It should be noted that data transmission in this invention refers not only to data transmission from the charging pile to the vehicle but also to data transmission from the vehicle to the charging pile; that is, data transmission is bidirectional, and the user can choose between the vehicle control system and the charging pile system.

[0067] In another optional embodiment, the data transmission method provided by this invention can also provide a separate charging option for the vehicle. Specifically, when the mode selection command indicates a second mode, a second interface on the charging gun interface is determined based on the power type; wherein the second mode indicates charging only the vehicle. Specifically, when the power type is AC, the L1 interface of the three-phase power supply on the charging gun interface is used as the second interface; or, when the power type is DC, the DC+ and DC- interfaces on the charging gun interface are used as the second interface.

[0068] The following example illustrates the data transmission process between the vehicle and the charging station. Figure 8 As shown, it includes:

[0069] Step S801: Using near-field communication and / or wireless communication, determine whether there is a target charging station that is matched with the vehicle within the preset range of the vehicle;

[0070] If so, proceed directly to step S806: monitor each charging gun on the target charging pile, and when the target charging gun is detected to be pulled out of the target charging pile, determine the power type according to the charging gun interface corresponding to the target charging gun.

[0071] If not, then execute steps S802 to S805 first, and then continue to execute step S8068 after step S805;

[0072] Step S802: Obtain one or more unmatched charging piles;

[0073] Step S803: In response to the user's charging pile selection command, determine the charging pile to be used;

[0074] Step S804: Send a matching request to the charging station to be used;

[0075] Step S805: Receive the matching result from the charging pile to be used in response to the matching request. If the matching result indicates that the matching is successful, use the charging pile to be used as the target charging pile.

[0076] Step S806: Receive the mode selection instruction sent by the user;

[0077] Step S807: When the mode selection command indicates that the selected mode is the first mode, determine the first interface on the charging gun interface for data transmission according to the power type; the first mode indicates that data transmission is performed while charging.

[0078] Step S808: Using a relay installed inside the vehicle, the power circuit connected to the first interface is changed from the first circuit to the second circuit; wherein the voltage of the second circuit is lower than the voltage of the first circuit;

[0079] Step S809: Use the first interface to transmit data with the target charging pile;

[0080] Step S810: When the target charging gun is detected to be inserted into the target charging pile, the power circuit connected to the first interface is restored from the second circuit to the first circuit using a relay.

[0081] The above Figures 1 to 8The vehicle data transmission solution provided by the embodiment shown improves the existing charging gun interface, providing a first interface for data transmission under different power types, enabling stable data transmission between the vehicle and the charging pile while the vehicle is charging.
