Description

A vehicle intelligent charging control method, device, medium and vehicle based on SOA architecture

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 2, 2024, with application number CN202410004431.9 and application name “A method, device, medium and vehicle for intelligent automobile charging control based on SOA architecture”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of vehicle body control technology, and specifically to automobile intelligent power replenishment control technology based on SOA architecture. Background Art

[0003] With the continuous development of automobile manufacturing technology, people's requirements for automobiles are getting higher and higher. How to further meet users' personalized needs and emphasize ride comfort, safety and environmental protection has become an important issue in body control.

[0004] SOA (service-oriented architecture) is a component model that breaks down an application's functional units (also known as services) and connects them through well-defined interfaces and protocols. Interfaces are defined in a neutral manner, independent of the hardware platform, operating system, and programming language used to implement the services. This allows services built on a wide variety of systems to interact in a unified and universal manner. Therefore, in applications, SOA breaks down the application's functional units, encapsulating the smallest functional logic into services. By invoking service interfaces, these different functional logic modules interact with each other and achieve data exchange.

[0005] Traditional vehicles utilize a distributed electrical and electronic architecture, with various functions controlled by dozens or even hundreds of ECUs. These ECUs utilize embedded software, with deep hardware and software integration, making upgrades difficult and interoperability impossible. In traditional software architectures, hardware and software are highly coupled, and signal-based communication lacks flexibility and scalability. Even minor functional changes require adjustments to the entire vehicle's software. SOA's service-oriented system architecture transforms cross-ECU interactions from "signal-based communication" to "service-based communication," making applications service-oriented and freely accessible to everyone with permission, making full vehicle intelligence possible. Flexible service deployment allows for different service deployments for different vehicle configurations throughout the vehicle's lifecycle, significantly reducing the coupling between hardware and software and enabling faster software updates and upgrades.

[0006] As new energy vehicles enter more and more households, the performance of vehicle power management determines their success in the fiercely competitive automotive market. The application of intelligent power distribution modules within the next-generation intelligent automotive electronic and electrical architecture enables intelligent energy-saving management based on vehicle status and environmental information, such as external temperature, vehicle voltage, BCU remaining charge, and BCU long-term discharge power. Therefore, by adopting a service-oriented architecture based on SOA, users can reconfigure intelligent charging functions to meet personalized needs. Summary of the Invention

[0007] In response to the problems existing in the prior art, this application provides an intelligent vehicle charging control method, device, medium and vehicle based on the SOA architecture, which realizes modular vehicle charging service through the SOA architecture, and improves the flexibility, scalability and maintainability of the charging function.

[0008] The technical solution of this application is as follows:

[0009] In its first aspect, the present application provides a method for controlling intelligent charging of an automobile based on a SOA architecture. The SOA architecture used by the method divides the software architecture into at least five layers, including: a system service layer, a basic service layer, an enhanced service layer, an atomic service layer, and an I / O abstraction layer. The method for controlling intelligent charging of an automobile based on the SOA architecture specifically includes the following steps:

[0010] The intelligent power replenishment system service of the system service layer obtains information from the basic service layer, enhanced service layer and atomic service layer to determine whether the triggering conditions of the intelligent power replenishment service are met.

[0011] When the triggering conditions are met, the intelligent charging system service calculates charging information, including charging duration, based on the environment and vehicle body information.

[0012] The high-voltage request basic service of the basic service layer receives the instruction of the intelligent charging system service to control the high voltage on the vehicle and perform charging according to the charging time.

[0013] Furthermore, the system service layer starts the smart power replenishment system service when a trigger condition is met, wherein the trigger condition includes a primary trigger condition and a secondary trigger condition, and the smart power replenishment service can only be started when both the primary trigger condition and the secondary trigger condition are met.

[0014] Preferably, there are two scenarios that meet the trigger condition:

[0015] First, after the vehicle is locked for a preset time, the power supply voltage atomic service of the atomic service layer obtains the vehicle voltage value, and the system service layer calculates the voltage average value. When the voltage average value is lower than the preset value, a trigger condition is met. Generally, the preset time for locking the vehicle is 20 to 60 minutes.

[0016] Second, after the vehicle network is completely dormant, when the SCR core processor monitors that the voltage of the I / O abstraction layer is lower than a preset value, a trigger condition is met to wake up the MCU.

[0017] Furthermore, after a trigger condition is met, the intelligent charging system service pulls up the entire vehicle network through the basic service layer, obtains vehicle information and environmental information from the vehicle controller VIU, and determines whether a secondary trigger condition is met.

[0018] Determining whether the secondary trigger conditions are met includes obtaining, through the basic services in the basic service layer, whether the remaining available power of the power battery is sufficient, whether the long-term discharge power of the power battery is sufficient, and whether the high-voltage system is operating normally; determining whether the entire vehicle network is operating normally; if the above judgments are all normal, the secondary trigger conditions are met.

[0019] Furthermore, once the trigger conditions are met, the intelligent charging system service determines the charging duration and other parameters based on the environment and vehicle body information, thereby recharging the vehicle. These parameters include the anomaly detection cycle, the voltage detection cycle and filtering parameters, and the waiting time between two charging triggers.

[0020] Furthermore, the end of the charging process includes normal and abnormal termination. When certain exit conditions are met, the intelligent charging service ends the car charging process normally; when certain disconnection conditions are met, the intelligent charging service ends the car charging process abnormally.

[0021] Furthermore, when the exception ends, the MCU wake-up method atomic service of the atomic service layer calls the MCU wake-up method I / O abstract service of the I / O abstraction layer to send instructions to the SCR core to wake up the car at a scheduled time; and when the number of exceptions exceeds the set value, a disable instruction is sent to the SCR core until the car is unlocked.

[0022] In a second aspect, the present application further provides an electronic device comprising: one or more processors; a storage device for storing one or more programs, wherein when the one or more programs are executed by the one or more processors, the electronic device implements the SOA-based intelligent vehicle charging control method provided in the first aspect.

[0023] In a third aspect, the present application further provides a computer-readable storage medium storing a computer program. When executed by a computer processor, the computer program causes the computer to execute the aforementioned SOA-based intelligent vehicle charging control method. The computer-readable storage medium may be included in the electronic device described in the second aspect, or may exist independently and not be incorporated into the electronic device.

[0024] In a fourth aspect, the present application further provides a vehicle, which is equipped with an electronic device, wherein the electronic device includes: one or more processors; a storage device for storing one or more programs, and when the one or more programs are executed by the one or more processors, the electronic device implements the SOA architecture-based automobile intelligent power charging control method as described in the first aspect of the present application.

[0025] By adopting the technical solutions described in the above aspects, this application has at least the following beneficial effects:

[0026] This application adopts an SOA architecture including a system service layer, a basic service layer, an enhanced service layer, an atomic service layer and an I / O abstraction layer. The intelligent charging system service of the system service layer obtains information from the basic service layer, the enhanced service layer and the atomic service layer to determine whether the triggering conditions of the intelligent charging service are met; when the triggering conditions are met, the intelligent charging system service calculates the charging information according to the environment and vehicle body information, including the charging time; the high-voltage request basic service of the basic service layer receives the instruction of the intelligent charging system service to control the high voltage on the car and charge according to the charging time; after the charging is completed, the intelligent charging system service controls the car to exit the charging and sends the process record information to the cloud platform through the communication interface of the basic service layer. The modular car charging service function is realized through the above SOA architecture. The SOA architecture provides a loosely coupled way to organize the system. Different services can be developed and maintained by different teams and can be independently expanded and modified. In addition, the above SOA architecture is also highly flexible and reusable because services can be shared and reused between different systems and applications, thereby improving the flexibility, scalability and maintainability of the car charging service function.

[0028] FIG2 is a schematic diagram of an SOA architecture according to an embodiment of the present application;

[0029] FIG3 is a simplified diagram of the SOA architecture of an embodiment of the present application. DETAILED DESCRIPTION

[0030] The following will provide a clear and complete description of the technical solutions in the embodiments of the present application, in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are intended only to explain the related application and are not intended to limit the application. It should also be noted that, for ease of description, only the portions relevant to the related application are shown in the accompanying drawings.

[0031] To address the challenges of existing technologies, this application provides an intelligent charging control method based on a SOA architecture. As shown in Figures 1, 2, and 3, this method utilizes an SOA architecture that includes a system service layer, a basic service layer, an enhanced service layer, an atomic service layer, and an I / O abstraction layer. This layered logic design allows developers to focus on their own areas of responsibility, ensuring that input parameters to external systems are correct.

[0032] in,

[0033] The system service layer includes the intelligent charging system service Sys_IntLoBattChrg. This system service layer is used to obtain real-time vehicle information, arbitrate relevant conditions, and then request function calls from the enhanced service layer. The system service layer includes intelligent charging system services. Specifically, the system service layer receives real-time vehicle information obtained through various basic services from the basic service layer, receives power supply voltage information from the atomic service layer, and invokes the power shift service Enh_PowerShiftDrv from the enhanced service layer to initiate the intelligent charging service when the trigger conditions are met.

[0034] The Enhanced Service Layer is responsible for parameter filtering of requests from the System Service Layer. When receiving multiple requests, it selects which service to execute based on a preset priority order and returns the requested parameters. The Enhanced Service Layer includes a Power Gear Service, which internally implements priority selection and provides the System Service Layer with access to power gear parameters.

[0035] The basic service layer includes basic services related to power replenishment control and is used to bidirectionally transmit information between CAN lines, LIN lines, and applications. This means transparently transmitting messages sent from CAN lines and LIN lines to applications and vice versa. As shown in the figure, the basic service layer includes various basic services related to power replenishment control, such as the high-voltage request basic service Basc_HvActvReq, the BCU operation information basic service Basc_PduOperInfo, the PDU operation information basic service Basc_PduOperInfo, the IBS configuration storage Basc_DID, the IBS sensor information Basc_IBSInfo, and the air conditioning status information service Basc_ACStsInfo.

[0036] The atomic service layer shields the upper layers from the impact of changes in the I / O abstraction layer, reducing software modifications required when functionality changes occur, and achieving decoupling. This atomic service layer reduces dependencies between different code blocks, minimizing the impact of changes to other code blocks on the underlying code. Specifically, the atomic service layer includes the MCU wakeup mode atomic service Atm_WUType and the power supply voltage atomic service Atm_VIUFRU.

[0037] The I / O abstraction layer is used to bind to the hardware layer, shielding hardware design from specific implementations. Specifically, this I / O abstraction layer provides the MCU wake-up method I / O abstraction service IO_WUType and the power supply voltage I / O abstraction service IO_VIUFRU. The interfaces provided by the I / O abstraction layer are only visible to the atomic service layer and cannot be directly called by other layers.

[0038] In some embodiments of the present application, a vehicle intelligent charging control method based on the SOA architecture, as shown in FIG1 , specifically includes the following steps:

[0039] Step 1: The intelligent charging system service of the system service layer obtains information from the basic service layer, enhanced service layer and atomic service layer to determine whether the triggering conditions of the intelligent charging service are met.

[0040] Step 2: When the trigger conditions are met, the intelligent charging system service calculates the charging information, including the charging duration, based on the environment and vehicle body information.

[0041] Step 3: The high-voltage request basic service of the basic service layer receives the instruction of the intelligent charging system service to control the high voltage of the car and charge it according to the charging time.

[0042] Step 4: After the charging is completed, the intelligent charging system service controls the car to exit the charging process and sends the process record information to the cloud platform through the communication interface of the basic service layer for analysis.

[0043] In some embodiments of the present application, the intelligent charging service of the system service layer is activated when a trigger condition is met, and the vehicle is charged. The trigger condition includes a primary trigger condition and a secondary trigger condition. The intelligent charging service is activated only when both the primary trigger condition and the secondary trigger condition are met.

[0044] In some embodiments of the present application, a trigger condition may be met in the following two scenarios:

[0045] The first scenario is that after the vehicle is locked for a preset time, the vehicle voltage value is obtained through the Atm_VIUFRU power supply voltage atomic service of the atomic service layer, and the average voltage value is calculated within the system service layer. When the average voltage value is lower than the preset value, the intelligent power replenishment system service is triggered.

[0046] According to actual needs, the optimal design here is to set the preset locking time of the entire vehicle to 20 to 60 minutes.

[0047] The second scenario is that after the entire vehicle network is completely dormant, the car's SCR core processor monitors the voltage of the I / O abstraction layer and wakes up the MCU when it is lower than the preset value.

[0048] In some embodiments of the present application, after the system service layer is triggered once, the intelligent charging system service will pull up the entire vehicle network through the IBS sensor information Basc_IBSInfo of the basic service layer, and obtain vehicle information and environmental information from the remaining vehicle controllers VIU through other basic services of the basic service layer (including the high-voltage request basic service, BCU operation information basic service, PDU operation information basic service, air conditioning status information service, etc. as shown in Figure 1), and further determine whether the secondary trigger conditions are met. The secondary trigger conditions include the following:

[0049] 1. Obtain whether the remaining available power of the power battery is sufficient through the BCU operation information basic service Basc_BcuOperInfo in the basic service layer.

[0050] 2. Check whether the long-term discharge power of the power battery is sufficient through the BCU operation information basic service Basc_BcuOperInfo in the basic service layer.

[0051] 3. Obtain whether the high voltage system is operating normally through the high voltage request basic service Basc_HvActvReq in the basic service layer.

[0052] 4. Whether the vehicle network is operating normally.

[0053] In some embodiments of the present application, when all the above conditions are met, that is, after the charging is triggered, the intelligent charging system service of the system service layer determines the charging duration and the cycle of abnormal detection, the cycle and filtering parameters of pressure detection, the waiting time between charging triggers and other parameters based on the environment and vehicle body information.

[0054] Afterwards, the intelligent charging system service requests high voltage from the VIU's Basc_HvActvReq high voltage request basic service. After the request is responded to, the timer starts and the connection with the VIU is confirmed every five minutes to ensure that the vehicle body is in a normal high voltage state until any of the following normal exit conditions are met, including:

[0055] 1. The recharging time reaches the preset duration;

[0056] 2. The current is continuously lower than the preset value for a period of time;

[0057] 3. The BCU operation information basic service is used to learn that the available energy decreases by a certain value during the charging process. For example, during the charging process, the available energy decreases by 2 kW or more, meeting the exit condition.

[0058] 4. Receive vehicle unlock information through the power level service of the enhanced service layer;

[0059] 5. The IBS sensor information indicates that the power signal is higher than the preset power value.

[0060] In some embodiments of the present application, if any of the following conditions is met during the power replenishment process, the power replenishment process is abnormally terminated and the cause of the abnormality is recorded:

[0061] 1. The Bcu operation information basic service of the basic service layer is used to know that the remaining available power of the power battery is insufficient;

[0062] 2. Through the Bcu operation information basic service of the basic service layer, it is learned that the power battery has been discharging insufficiently for a long time;

[0063] 3. The high-voltage system failure is learned through the high-voltage request basic service of the basic service layer;

[0064] 4. The vehicle network is abnormal.

[0065] After an exception occurs, the continuous exception count in the current wake-up cycle is increased by 1, and the total number of exceptions is increased by 1.

[0066] When a power battery-related abnormality occurs (i.e., the first and second abnormalities above), the smart power charging service sends an instruction to the SCR core processor through the Basc_IBSInfo basic service to disable the smart power charging service. That is, when the MCU is in sleep mode, the smart power charging service will not be awakened because the voltage is lower than the preset value.

[0067] Here, the disable instruction is sent to the SCR core, which means that under normal circumstances, after detecting low voltage, the SCR core will wake up the processor where the smart power replenishment service is located, and then the smart power replenishment service will run. After the SCR core receives the disable instruction, it will not wake up the processor even if it detects low voltage.

[0068] When other exceptions occur (i.e., the 3rd and 4th exceptions above), the SCR core wake-up mode is changed to timed wake-up through the Basc_IBSInfo basic service, that is, the MCU is woken up every half hour when the voltage is lower than the preset value. It is expected that the abnormalities of the high-voltage system and the vehicle network have been restored at this time. If the abnormality occurs 4 times in a row, it will be directly disabled.

[0069] In some embodiments of the present application, if the MCU is not in sleep mode after an exception occurs, the precondition is judged again and high-voltage service is requested after a set time (for example, half an hour later). If successful, the continuous exception count is reset and the SCR core wake-up mode is restored to low-voltage wake-up.

[0070] In some embodiments of the present application, after the power replenishment is completed, the system will also send the first trigger reason, second trigger reason, normal end reason, abnormal end reason, wake-up times, total power replenishment times, and abnormal end times to the cloud platform through the Basc_IBSInfo basic service communication interface for analysis.

[0071] In some embodiments of the present application, when all the above abnormal conditions are restored, the smart power replenishment service is restored to trigger the source and a notification is sent to the outside, indicating that the smart power replenishment service is restored.

[0072] In some embodiments of the present application, an electronic device is also provided, including: one or more processors; a storage device for storing one or more programs. When the one or more programs are executed by the one or more processors, the electronic device implements the SOA architecture-based automobile intelligent power charging control method provided in the above-mentioned embodiments.

[0073] In some embodiments of the present application, a computer-readable storage medium is provided, storing a computer program. When executed by a computer processor, the computer program causes the computer to execute the aforementioned SOA-based intelligent vehicle charging control method. The computer-readable storage medium may be included in the electronic device described in the above embodiments, or may exist independently and not be incorporated into the electronic device.

[0074] In some embodiments of the present application, a vehicle is further provided, wherein the vehicle is equipped with an electronic device, and the electronic device includes: one or more processors; a storage device for storing one or more programs, and when the one or more programs are executed by the one or more processors, the electronic device implements the SOA architecture-based automobile intelligent power charging control method as described in the above-mentioned embodiment.

[0075] From the above embodiments, it can be seen that the present application provides a loosely coupled approach to organize the system through the SOA architecture, realizes modular vehicle charging service functions, enables services to be shared and reused between different systems and applications, and improves the flexibility, scalability and maintainability of the vehicle charging service functions.

[0076] The above description is merely an embodiment of the present application and is not intended to limit the scope of protection of the present application. Any modifications, equivalent replacements, and improvements made within the spirit and scope of the present application are included in the scope of protection of the present application.
