[0037] First, the application scenario of the present application is described. The technical solution of the present application is applicable to the development of SWC of vehicles, and specifically relates to the design for the demand of vehicle seat heating function.
[0038] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.
[0039] Embodiment 1
[0040] Figure 1 This is a schematic diagram of the structure of a vehicle control system provided in an embodiment of the present application. Figure 1 In one embodiment of the present application, a vehicle control system is provided, the system comprising a first zone controller, a second zone controller and an air conditioning controller. The first zone controller is used to respond to user operations, generate a status signal, and send the status signal to the second zone controller. The second zone controller is used to generate a seat control signal according to the status signal, and send the seat control signal to the air conditioning controller. The air conditioning controller is used to control the heating state of the target seat based on the seat control signal.
[0041] The first zone controller serves as the main input interface of the system. It is responsible for receiving operation instructions from the user (such as the operation of the seat heating switch) and converting these instructions into corresponding status signals.
[0042] For example, when the user chooses to turn on the seat heating function through the vehicle-mounted touch screen, the first zone controller generates a status signal indicating "changing the seat heating status" after receiving this operation.
[0043] The second zone controller is an intermediate processing unit, which is used to analyze the status signal received from the first zone controller and generate a corresponding seat control signal accordingly. According to the received status signal, the second zone controller determines whether the seat heating function needs to be activated. If it is confirmed to be necessary, the seat control signal is generated; otherwise, the signal is not generated.
[0044] The air conditioning controller is the final execution unit, which is responsible for receiving the seat control signal from the second zone controller and adjusting the heating state of the target seat according to the signal. Once the seat control signal is received, the air conditioning controller immediately starts or stops the seat heating module, thereby completing the control of the seat temperature.
[0045] The vehicle control system provided in the present application provides a sub-region control architecture for the vehicle seat heating function, which provides a good operating environment for SWC design and a solid foundation for subsequent system upgrades.
[0046] Embodiment 2
[0047] In one embodiment of the present application, based on the vehicle zone control architecture, a SWC design scheme is proposed for the vehicle seat heating function.
[0048] The first zone controller here includes an application module and a collection module. The application module is used to obtain a first user operation of a user on a virtual heating control through the vehicle central control screen. In response to the first user operation, a screen button state signal is generated. The screen button state signal is sent to the second zone controller. The collection module is used to generate a usage status of the target seat and send it to the SA module of the second zone controller.
[0049] The second zone controller includes an SA module and a VC module. The SA module is specifically used to determine the target seat based on the button status signal. Obtain the usage status signal of the target seat and the heating status signal of the target seat. Generate a seat control signal based on the usage status signal and the heating status signal of the target seat. The VC module is used to obtain the usage status of the target seat generated by the acquisition module and send it to the SA module.
[0050] In a specific embodiment, Figure 1 and Figure 2 As shown, the first area controller may be a vehicle-mounted controller, which is divided into an application layer and a hardware abstraction layer. The second area controller here may be a seat heating controller, which is divided into a SA layer (sensor and actuator layer) and a VC layer (vehicle control layer).
[0051] The user operates the virtual heating controls (such as icons or buttons) on the central control screen. The application layer captures the user's touch, click, or slide actions and identifies the specific user intention (for example, "turn on seat heating" or "adjust seat temperature level"). According to the user operation, the corresponding screen button state signal (such as "HEAT_ON", "TEMP_LEVEL_UP", etc.) is generated.
[0052] When the application layer detects the first user operation on the virtual heating control, the state signal generation process is immediately triggered.
[0053] The screen button status signal not only includes the user's operation type (such as on / off) and the identification of the target seat, but may also include additional parameter information (such as temperature setting value).
[0054] The generated screen button status signal can be sent to the second area controller via an internal communication bus (such as a CAN bus or a LIN bus) to ensure the real-time and reliability of data transmission.
[0055] The Hardware Abstraction Layer (HAL) acts as a bridge between the application layer and the underlying hardware, ensuring that the operations of the application layer can be accurately mapped to the underlying hardware resources. The hardware abstraction layer is specifically responsible for managing the data acquisition tasks of sensors and other hardware interfaces. It converts the status signals received from the application layer into a format suitable for transmission to the second regional controller.
[0056] The SA layer focuses on the specific control logic of seat heating. It is responsible for determining the target seat based on the button status signal and generating a seat control signal based on the seat's usage status and heating status. The SA layer can receive the screen button status signal generated by the application module from the first area controller to determine the target seat that needs to be heated. The usage status signal and heating status signal of the target seat are obtained from the VC layer. According to the usage status and current heating status of the target seat, the corresponding seat control signal (such as starting heating, adjusting temperature, etc.) is generated.
[0057] The VC layer is responsible for collecting and transmitting relevant information such as seat usage status, obtaining and transmitting the usage status signal of the target seat, receiving the target seat usage status signal generated by the acquisition module of the first zone controller, and sending these usage status signals to the SA module for further processing.
[0058] In this embodiment, by dividing each controller into multiple functional modules, effective decoupling of software and hardware is achieved, which is convenient for later maintenance and function expansion. By real-time monitoring of the use status of the target seat, the intelligent level of seat heating control is improved, and the user experience is enhanced.
[0059] The SWC design proposed in this application not only improves the intelligence and flexibility of the vehicle seat heating function, but also lays a solid foundation for future functional upgrades and personalized customization. By carefully dividing the internal modules of each controller, the solution can easily integrate new functional modules without affecting the existing system structure to meet the ever-changing market needs and technological development trends.
[0060] Furthermore, the SA module can generate seat control signals in the following ways:
[0061] It is determined whether the usage state of the target seat is a seat-out state.
[0062] If it is the seat leaving state, it is determined whether the heating state signal of the target seat is in the heating state, and if so, a seat heating off signal is generated.
[0063] If the seat is occupied, it is determined whether the heating state signal of the target seat is in the heating state. If so, a seat control signal is generated based on the seat heating level indicated by the heating state signal.
[0064] The SA module generates a seat control signal based on the seat heating level indicated by the heating status signal, specifically including:
[0065] A next heating level of the seat heating level indicated by the heating status signal is determined.
[0066] Based on the next heating level, a seat heating de-stage signal is generated to control the heating level of the target seat to be reduced to the next heating level.
[0067] The SA layer needs to determine the current usage status of the target seat (vacant or occupied). If it is vacant, enter the vacant processing flow. If it is occupied, enter the occupied processing flow.
[0068] The seat-leaving status processing logic includes:
[0069] When the target seat is in the unseated state, the SA layer needs to further check the heating state of the seat. If the heating state is heating, a seat heating off signal is generated to stop the seat heating. If the heating state is not heating, no control signal is generated and the current state is maintained.
[0070] In this way, vehicle energy can be saved, unnecessary heat accumulation can be avoided, and vehicle safety can be ensured.
[0071] The seat occupancy status processing logic includes:
[0072] When the target seat is occupied, the SA layer needs to perform further processing based on the heating status of the seat. If the heating status is not heated, decide whether to start the heating function based on user needs or other preset conditions. If the heating status is heating, continue to perform the following steps:
[0073] Determine the current heating level: extract the current seat heating level from the heating status signal. Determine the next lower heating level based on system settings or user preferences. Based on the determined next heating level, generate a corresponding seat heating de-rating signal to control the heating level of the target seat to be reduced to the next heating level.
[0074] For example, when the seat heating state is not heated, after the user clicks the virtual heating control or the physical heating button, the seat heating can be turned on to level 2. When the seat heating state is level 2, after the user clicks the virtual heating control or the physical heating button, the seat heating can be reduced to level 1. When the seat heating state is level 1, after the user clicks the virtual heating control or the physical heating button, the seat heating can be turned off. Here, the temperature of heating level 2 should be greater than the temperature of heating level 1.
[0075] By gradually decreasing the seat heating level, a more comfortable temperature regulation experience can be provided.
[0076] The logic of the SA layer generating seat control signals proposed in this application not only realizes the refined control of the seat heating function, but also significantly improves the system's energy efficiency and user experience through intelligent state monitoring and response mechanisms. By defining the processing logic in each state in detail, the stability and reliability of the system in different application scenarios are ensured.
[0077] In one embodiment of the present application, the second zone controller also includes a complex drive module. The complex drive module is used to receive seat heating requests and drive the air conditioner to work. It is also responsible for collecting the response information of the air conditioning system to the seat heating request, including whether the heating is successfully started, the current heating intensity, etc., and forwarding this information to the SA layer or a higher-level control system. This ensures the overall coordination of the system and the transparency of information.
[0078] Specifically, the complex drive module can process seat heating requests and air conditioning control signals through a microprocessor and an application specific integrated circuit (ASIC).
[0079] In this way, through the design of a complex drive module, the user experience of the seat heating function can be effectively improved without changing the original air-conditioning system structure, while also facilitating system fault diagnosis and performance optimization.
[0080] In a specific embodiment of the present application, the external Port, Interface, parameter type, etc. of each module / layer are defined.
[0081] Among them, the naming convention needs to ensure the consistency and readability of the naming of the interface and its methods, parameters, return values, etc.
[0082] Naming conventions can include camelCase or snake_case and should be used consistently according to the standards within the organization. Verb + noun combinations are used for method names, such as `getUserInfo()` or `update_user_status`. Prefixes or suffixes can be used to identify specific types of methods or variables, for example, `isUserActive` (Boolean value), `getUserList` (get list).
[0083] Provide developers with clear function descriptions, parameter descriptions, return value types, and possible exception information to ensure that the interface is easy to understand and use. It is necessary to define comment documents. Use consistent document formats, such as Markdown, ReST, or APIBlueprint, to facilitate automated generation and maintenance.
[0084] The contents of the annotation document include:
[0085] Functional description: briefly describe the main functions of the interface;
[0086] Parameter description: List in detail the name, type, whether it is required, and default value of each parameter;
[0087] Return value type: clearly define the returned data structure and type;
[0088] Exception information: lists the exceptions that may be thrown and their causes;
[0089] Version control information also needs to be defined to ensure that interface changes can be effectively tracked and recorded to reduce the impact on existing systems. Specifically, this may include defining the following:
[0090] Semantic Versioning: follows the format of `MAJOR.MINOR.PATCH`, for example `1.2.3`;
[0091] `MAJOR`: Incompatible API changes;
[0092] `MINOR`: backwards-compatible functionality additions;
[0093] `PATCH`: backward compatible bug fixes;
[0094] Version release log: Each time a version is updated, all changes are recorded, including new features, fixed issues, and incompatible changes;
[0095] Migration path: For incompatible changes, a detailed upgrade guide is provided to help developers smoothly transition to the new version.
[0096] Data specifications, data formats, and encoding methods also need to be considered.
[0097] Define the data format, encoding method and data verification rules involved in the interface interaction process to ensure the accuracy, consistency and security of the data.
[0098] The data format can be JSON, XML or other standard formats, which should be selected according to specific needs. And the name, type and constraints of the field should be clearly defined, for example, some fields must be integers, string length restrictions, etc.
[0099] The encoding method can use UTF-8 as the default encoding to ensure character set compatibility.
[0100] Finally, data validation is required. Perform input validation at the interface level to ensure that the received data conforms to the expected format. You can use the built-in validation mechanism provided by the library or framework, such as `pydantic` in Python, `Joi` in JavaScript, etc.
