These embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore merely examples, and should not be construed as limiting the scope of protection of the present invention.

[0067] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0068] To address the aforementioned issues, this invention provides a vehicle charging system, method, and vehicle based on SOA architecture, offering a novel solution for the design of charging functions for new energy vehicles, and possessing significant technical advantages and application value.

[0069] In one embodiment, the present invention provides a vehicle charging system based on an SOA architecture. The embodiment of the present invention will be described below with reference to the accompanying drawings. Please refer to... Figure 1 The system specifically includes: a central control screen, functional links, and a CSC vehicle cockpit controller; it also includes multiple function setting modules for setting the charging port cover function, charging and discharging function, remaining charging time display, remaining discharging time display, and charging limit; the function setting modules are set in the central control screen and are used to set the vehicle charging function according to the charging and discharging status information displayed in real time on the central control screen; and trigger at least one user operation command based on the setting result to generate a function control request signal; wherein, the function control request includes control commands for opening / closing the charging port cover, charging and discharging, remaining charging / discharging time display, and SOC charging limit;

[0070] The functional link includes the application layer, adaptation layer, SOA layer, communication management module (CM) and SOME / IPD middleware, Ethernet, and battery management controller (BMS).

[0071] The SOA layer uses the SOME / IP protocol to implement service calls between the application layer and the battery management controller (BMS).

[0072] The application layer converts the function control request signal into the SOA layer SOME / IP protocol via the adaptation layer, and transmits it to the battery management controller BMS via Ethernet through the communication management module CM and SOME / IPD middleware.

[0073] The battery management controller (BMS) sends a function control request signal to the CSC vehicle cockpit controller. After the CSC vehicle cockpit controller executes the user operation command, it feeds back the status signal to the central control screen and the peer IP. After being parsed by the SOA layer, the status signal is transmitted to the application layer by the adaptation layer.

[0074] The central control screen receives status signals from the application layer to update the display of charging and discharging status information, and updates the function status in real time on the IVI in-vehicle infotainment system according to the predefined operation response time and status refresh cycle.

[0075] In the above embodiments, in the communication management module CM, CM (Communication Management) refers to communication management; the communication management module is a common basic component of communication management and an important part of the functional cluster; the role of communication management is to establish and supervise the communication path between local and remote applications.

[0076] SOME / IP (Scalable Service-Oriented Middleware over IP) is a lightweight communication protocol over IP networks, widely used in automotive electronics, industrial automation, and the Internet of Things (IoT). The SOME / IP protocol supports various message transmission modes, including request / response, event / subscription, and notification, enabling real-time message delivery, service discovery, service registration, and service invocation. Furthermore, SOME / IP provides rich security and reliability mechanisms to ensure data security and reliability during communication.

[0077] Service-Oriented Architecture (SOA) is a high-level architectural design concept that enables the reusability of software components through service interfaces based on a common communication language over a network. It combines different functional units (services) of an application through well-defined interfaces and protocols. These services are independent, reusable, and can interact across multiple systems and organizations. The goal of SOA is to improve the flexibility, scalability, and maintainability of software systems.

[0078] SOMEIPD is the background process of SOMEIP, responsible for service discovery, data forwarding, and other functions. The configuration file for someipd needs to contain all the service information required for the host's external communication.

[0079] The application layer is the highest layer in the Open Systems Interconnection (OSI) model. It directly faces the user and provides commonly used network application services. This layer also sends requests to the presentation layer. The application layer has many protocols, each corresponding to a specific service. The main task of the application layer is to enable users to complete various network-related applications in a simple and efficient way.

[0080] The adaptation layer is an abstraction layer between an application and a computer, ensuring that the application is compatible with different operating systems or hardware environments. The adaptation layer mainly consists of two types: middleware, such as the Java Virtual Machine and the .NET Framework, which allow cross-platform applications to run; and drivers, such as printer drivers and network adapter drivers, which enable hardware devices to function correctly on the operating system. The adaptation layer makes software development easier and more flexible because it resolves incompatibility issues between applications and operating systems, freeing developers from worrying about the underlying details.

[0081] In-Vehicle Infotainment (IVI) is a comprehensive in-vehicle information processing system that utilizes a dedicated onboard central processing unit, based on the vehicle bus system and internet services. IVI enables a range of applications including 3D navigation, real-time traffic updates, IPTV, driver assistance systems, fault detection, vehicle information, vehicle control, mobile office capabilities, wireless communication, online entertainment functions, and TSP services, significantly enhancing the vehicle's electronic, networked, and intelligent capabilities.

For example, when entering the page, it retrieves the on / off status of the manual charging limit setting; if no successful feedback is received within 2 seconds after setting, it restores the previous setting display; clicking on the manual charging limit setting executes related actions and sends downlink signals; and when a signal is received within 2 seconds, it updates the setting status.

[0116] In one embodiment, the present invention elaborates in detail the specific function of each of the above-mentioned function settings, as well as the preconditions and postconditions. It explains the prerequisites for triggering the entire function and the system status after the function is turned on or off. The present invention designs the basic path for function activation, and by describing the user's operation sequence, it clearly explains the methods for turning each function on or off and the display status of the central control screen. At the same time, it also provides a detailed explanation of the specific requirements of each function and provides the relevant signals required by the function.

[0117] Specifically, 1. Charging port cover switch enable setting

[0118] Function Description: The central control unit features a charging port cover status icon that refreshes and displays based on charging status updates. It also supports success and failure prompts for charging port cover operation.

[0119] Function activation path and prerequisite / post-conditions:

[0120] 1. After the user enters the charging application interface on the central control screen, the latest status of the current charging port cover enable switch is displayed.

[0121] 2. Press the soft button to open or close the charging port cover;

[0122] 3. The charging port cover will open / close accordingly based on the settings.

[0125] Post-conditions: The charging port cover opens or closes according to the settings, and the latest status of the charging port cover is displayed on the central control screen.

[0126] Functional Logic: Upon entering the page, the switch status is retrieved. If the switch status is not retrieved within 2 seconds, or if an abnormal value is retrieved, the switch is grayed out. If it has already been set, the switch action is executed, and a downlink signal is sent. If the central control receives a signal (0, 1) within 2 seconds, it will update the switch status promptly. If the uplink status is the same as the previous switch status, it will bounce back and display "Setting failed"; if an abnormal signal is received, the switch is grayed out, and the setting fails. If the relevant setting item is not enabled, it is grayed out.

[0127] Functional link description: in order, application layer, adaptation layer, SOA, CM, SOMEIPD, Ethernet, BMS.

[0128] Charging port cover enable setting instructions: After the user operates the charging port cover enable setting switch, a corresponding signal will be sent to the BMS. At this time, the BMS will send the HMIVw_NotifyOnChgACChargeSt charging port cover signal to the CSC. After receiving the signal, the CSC will send Dis_NotifyONChgNOPEnableSwitchSt to the peer IP to inform the peer that the charging port cover enable setting switch status has changed. This signal is equivalent to a request signal. At the same time as sending the signal, the change signal of the charging port cover enable setting is transmitted to the application layer through the SOA layer and the adaptation layer, and then the latest status of the switch can be displayed on the screen.

[0129] Detailed functional requirements:

[0130] (1) The system supports the setting to enable or disable the charging port cover, which is disabled by default;

[0131] (2) The function activation settings interface should have text descriptions and icon displays of the corresponding functions, and set corresponding toggle switches to enable and disable the functions;

[0137] Function Description: The system supports the display of charging / discharging status, specifically: charging started, charging, charging stopped, charging completed, charging scheduled, charging will start at ××:××, AC discharging in progress. Other charging / discharging states are not indicated on the charging interface.

[0138] Different charging states should be indicated by corresponding icons, as shown below:

[0139] 1. "Not charging / discharging" icon: The charging / discharging gun is fully connected && the charging / discharging status is the status bits except (2) to (4);

[0140] 2. "Charging" icon: The charging / discharging status is "AC charging", "DC charging", "charging and heating", or "wireless charging".

[0141] 3. "Discharging" icon: The charging / discharging status is "AC discharging".

[0142] 4. "Charging Reserved" icon: The charging / discharging status is "Charging Reserved";

[0143] 5. Do not display the charging interface icon: Other states except for (1) to (4) above;

[0144] Function activation path and prerequisite / post-conditions:

[0145] 1. Users enter the charging information display interface on the central control screen, which displays the latest charging status;

[0146] 2. The central control unit's charging interface displays charging and discharging status information based on the latest status provided by the external controller;

[0147] Prerequisites: System is in normal working condition (Standby, Driving, Pre-Off) && Screen is on && AC charging gun or AC discharging gun or DC charging gun is fully connected or wireless charging is successfully aligned.

[0148] Post-condition: The system supports displaying the charging and discharging status based on information provided by an external controller;

[0149] Functional logic: Upon entering the page, obtain the charging / discharging gun status. If no uplink signal is received within 2 seconds, the switch is grayed out. If no charging / discharging status value is received, or the received status value is invalid for less than 2 seconds, maintain the current status display; if it is ≥2 seconds, do not display the status.

[0150] Functional link description: in order, application layer, adaptation layer, SOA, CM, SOMEIPD, Ethernet, BMS.

[0151] Charging and discharging function settings instructions: After the user connects the charging gun, it will send the corresponding signal to the BMS. At this time, the BMS will send the EECo_NotifyOnChgCharger Status signal to the CSC. After receiving the signal, the CSC will send HMI_View_ProvideViewForChargingInfomationDisplayStatus to the peer IP to inform it that the peer's charging and discharging status has changed. This signal is equivalent to a status signal. At the same time as sending the signal, the signal indicating the change in charging and discharging status is transmitted to the application layer through the SOA layer and the adaptation layer, and then the latest status can be displayed on the screen.

[0152] Detailed functional requirements:

[0153] After the charging / discharging gun is successfully connected or aligned, the system should periodically check the charging / discharging status, with a check period not exceeding 50ms. Textual indications of the charging / discharging status are only displayed on the charging interface of the instrument panel, central control unit, and remote APP.

[0154] When the instrument panel and central control unit do not receive the charging / discharging status value sent by the system, or the received status value is invalid for less than 2 seconds, the existing status display will be maintained; when the instrument panel and central control unit do not receive the charging / discharging status value sent by the system, or the received status value is invalid for more than 2 seconds, the status display will not be performed.

[0155] When the system determines that the vehicle has met the conditions for conductive charging or conductive charging, and has started the conductive charging or conductive charging process, but the power battery has not yet entered the charging state, the instrument panel, central control unit, and remote APP will indicate "Charging started" on the charging interface.

[0156] 4. When the vehicle's power battery BMS changes from charging to charging stopped, and the instrument panel's SOC value has not reached the user-set charging limit, the instrument panel, central control unit, and remote APP will display "Charging stopped" on the charging interface.

[0157] 5. When the vehicle's power battery status is "charging complete", the instrument panel, central control unit, and remote APP will display "charging complete" on the charging interface.

[0158] 6. When the vehicle charging status is "Charging Started" or "Charging Heating", if the user has only changed the timed charging switch or the timer setting, VDC will control the charging process and display the corresponding charging status according to the latest charging request. If the user sets the vehicle to be in timed charging mode and the current time is outside the timer period, the charging status should display "Charging has been scheduled and will start charging at XX:XX".

[0159] 7. When the vehicle is in the "charging stopped" state, if the VDC determines that the user has changed the timed charging switch or the timer setting, the VDC will control the charging process and display the corresponding charging status according to the latest charging request. If the user sets the vehicle to be in timed charging mode and the current time is outside the timer period, the VDC will send a "charging status reset" signal to the BMS. The BMS charging status should jump from "charging stopped" to the initial state, and the VDC will indicate the charging status according to the established strategy.

[0160] 8. When the vehicle is currently in the "charging complete" state, if the user has only changed the timed charging switch or the timer setting, the vehicle will still be in the "charging complete" state because the BMS has no charging request, and the VDC charging status indicator will still show "charging complete".

[0161] 9. If the charging gun is fully connected and the vehicle is currently in the "charging complete" state, and the user readjusts the charging limit to be greater than the current SOC displayed on the instrument panel, and the timed charging switch is turned on and the timed period has not yet arrived, the BMS should reset the charging request to "requested" and restore the charging status to the initial state. The instrument panel will display "Charging has been scheduled and will begin at XX:XX".

[0162] 10. If the vehicle stops charging before reaching the charging limit while in timed charging mode, the BMS charging status will be "Charging Stopped" and the instrument panel will display "Charging Stopped".

[0172] Functional link description: in order, application layer, adaptation layer, SOA, CM, SOMEIPD, Ethernet, BMS.

[0173] Remaining charging time function setting instructions: After the user inserts the charging gun, a corresponding signal will be sent to the BMS. At this time, the BMS will send the HVB_NofifyCycleHvBattRemainingCharTime signal to the CSC. After receiving the signal, the CSC will change the display of the remaining charging time. This signal is equivalent to a refresh status signal. At the same time as sending the signal, the signal to change the remaining charging time function is transmitted to the application layer through the SOA layer and the adaptation layer, and then the latest status can be displayed on the screen.

[0188] Functional link description: in order, application layer, adaptation layer, SOA, CM, SOMEIPD, Ethernet, BMS.

[0189] Remaining discharge time function setting instructions: When the user enters the interface displaying the remaining time, a corresponding signal will be sent to the BMS. At this time, HAD will send the HMI_View_ProvideViewForChargingInfomationDisplayStatus signal to CSC. After receiving the signal, CSC will update the remaining discharge time display on the interface in real time. This signal is equivalent to an update request signal. After the change signal is transmitted to the application layer through the SOA layer and the adaptation layer, the latest status of the switch can be displayed on the screen.

[0219] Daily driving: 50%-80%, faster charging and helps extend battery life;

[0220] For long-distance driving: 80%-100%, it will take longer to charge to this level.

[0221] In the above embodiments, the battery management controller (BMS) includes:

[0222] A status detection module, and an exception handling module connected to the status detection module;

[0223] The status detection module is used to detect the functional status of different function setting modules under function control requests;

[0224] The exception handling module is used to activate the graying or bounce mechanism for communication timeouts and invalid status values ​​in the current functional state.

[0225] The CSC vehicle-mounted cockpit controller includes:

[0226] The execution module is used to execute control commands for opening / closing the charging port cover, charging and discharging, displaying the remaining charging time, displaying the remaining discharging time, and controlling the SOC charging limit, based on the function control request signal.

[0227] In one embodiment, regarding the overall implementation process of the above system, this invention implements the charging module design method of this invention by taking a certain model of automobile as an example and combining it with SOA architecture. In new energy vehicle models, the central control screen realizes comprehensive control and display of the vehicle's charging function, including functions such as opening and closing the charging port cover, viewing the charging and discharging status, real-time updating and displaying the remaining charging and discharging time, and manually setting the charging limit. The specific implementation methods of each functional module are as follows:

[0228] Charging port cover function setting submodule: After the user enters the charging application interface on the central control screen, they can click the charging port cover open / close soft button. The system controls the opening or closing of the charging port cover according to the settings and displays the latest status of the charging port cover on the central control interface. For example, when the user clicks to open the charging port cover, the system sends a command to the BMS, the BMS sends a signal to the CSC, and after receiving the signal, the CSC sends a corresponding signal to inform the peer IP that the on / off state of the charging port cover enable setting has changed. At the same time, this signal is transmitted to the application layer through the SOA layer and the adaptation layer, and the central control screen displays that the charging port cover is open.

[0229] Charging / discharging function settings submodule: When the user enters the charging information display interface on the central control screen, the system displays charging / discharging status indication information based on the latest status provided by the external controller. For example, when the vehicle is charging, the central control screen displays a "Charging" icon and related information; when the vehicle is AC discharging, it displays a "Discharging" icon and related information.

[0230] Remaining charging time setting submodule: When the user enters the central control screen interface, the external controller calculates the remaining charging time and sends an update notification. The central control charging interface refreshes and displays the remaining charging time according to the notification. For example, when the vehicle is charging, the central control screen displays the current remaining charging time as 30 minutes, and updates the display in real time as the charging process progresses.

[0231] The remaining discharge time display function setting submodule: When the user enters the charging information interface and the vehicle is in "AC discharge" mode, the external controller calculates the remaining discharge time and sends an update notification. The central control screen then displays the remaining discharge time. For example, when the vehicle is in AC discharge mode, the central control screen displays the current remaining discharge time as 2 hours and updates the display in real time.

[0232] The manual charging limit setting submodule allows users to access the charging information interface, then the charging SOC limit setting interface, and set the SOC charging limit. The external controller controls the limit based on the setting result, and the charging interface updates accordingly. For example, if the user sets the charging limit to 80%, the system will automatically complete charging when the vehicle reaches 80% and display "charging complete" on the central control screen.

[0233] Through the above implementation methods, the present invention achieves an optimized design of the charging module in a new energy vehicle model, improving the user's operational convenience and the timeliness and accuracy of information acquisition during the charging process, thereby enhancing the market competitiveness of new energy vehicles.

[0236] After the S102 executes the user operation command in the CSC vehicle cockpit controller, it feeds back the status signal to the central control screen and the peer IP through the functional link and the battery management controller (BMS).

[0237] S103 updates the display of charging and discharging status information based on feedback status signals, and updates the function status in real time on the IVI in-vehicle infotainment system according to the predefined operation response time and status refresh cycle.
