Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0030] It should be understood that the various steps described in the method embodiments of the present application can be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present application is not limited in this respect.

[0031] Example 1

[0032] The embodiment of the present application provides a vehicle electronic and electrical architecture layered topology structure, such as Figure 1 As shown, Figure 1 A schematic diagram of a vehicle electrical and electronic architecture hierarchical topology structure provided in an embodiment of the present application, wherein the vehicle electrical and electronic architecture hierarchical topology structure includes:

[0033] The minimum control system layer 10 is used to control the basic functions required when the vehicle is in motion;

[0034] The standard control system layer 20 is used to cover the standard functions of the vehicle and is suitable for system configuration in a platform-based configuration mode to meet the needs of rapid application development of the project;

[0035] The customized system layer 30 is used to provide corresponding vehicle configurations based on the functional requirements proposed by customers, so as to realize the customized configuration requirements of different projects;

[0036] The value-added system layer 40 is used to provide a variety of software value-added services related to vehicles to meet users' increasing demand for smart cars;

[0037] The minimum control system layer 10 controls the operating state of the vehicle when a failure occurs in the standard control system layer 20 .

[0038] Specifically, in one implementation of the embodiment of the present application, the basic functions involved in the minimum control system layer 10 include: turning on the power steering function, the braking function, the torque output function, the high-voltage power on and off function, the low-voltage management function, configuring and shutting down the intelligent driving function and one or more of the entertainment domain related functions. By controlling these basic functions, the minimum control system layer 10 can operate independently of other control systems of the vehicle to increase the robustness of vehicle control. In the embodiment of the present application, the minimum control system layer 10 is configured as an emergency system control layer with high system safety. Its function is to meet the basic form requirements of the vehicle, and has characteristics such as stability similar to that of traditional vehicle control systems and power consumption lower than the preset value.

[0039] Optionally, in one implementation of the embodiment of the present application, as Figure 1 As shown, the control input information of the minimum control system layer 10 includes the vehicle operation-related information collected by the sensor group 101 in the hardware 50 set in the vehicle, including at least one of the sensor input information necessary to ensure the basic operation of the vehicle, such as vehicle speed, throttle opening, brake opening, key signal, gear signal, steering wheel angle and brake pressure; its control output includes control information of the actuator group 102 corresponding to the cooling, including at least one control parameter of the parameters for controlling the actuators necessary to ensure the basic operation of the vehicle, such as the vehicle drive motor, power battery, DCDC, brake steering, etc.

[0040] Specifically, in one implementation of the embodiment of the present application, when the minimum control system layer 10 fails in OTA refresh or a failure occurs in the standard control system layer 20, such as a high-level vehicle failure, resulting in the standard control system layer being unable to control the vehicle, the vehicle's control functions are configured to meet the vehicle's basic driving needs, and the vehicle's electrical energy is reasonably allocated to enable the vehicle to obtain the maximum mileage.

[0041] Optionally, in one implementation of the embodiment of the present application, the minimum control system layer 10 has an independent power supply, which is used to power the minimum control system layer 10 when the vehicle's main power supply fails to ensure normal driving of the vehicle. Specifically, when the minimum control system layer 10 is awakened, it diagnoses whether the vehicle's main power supply has failed. When it is determined that the vehicle's main power supply has failed and cannot power the vehicle, the independent power supply is also awakened to provide independent power supply, thereby preventing the normal operation of the minimum control system layer 10 from being affected by other function or system failures, and ensuring the stable operation of the minimum control system layer 10.

[0042] In an optional implementation of an embodiment of the present application, when the minimum control system layer 10 is awakened to take over the control of the vehicle, the minimum control system layer 10 controls the vehicle to be in a power-saving state by controlling the components involved in other peripheral system layers to shut down or reduce power operation, so as to ensure that the vehicle can achieve a longer mileage.

[0043] In an optional implementation of an embodiment of the present application, the standard control system layer 20 is configured with an independent power supply, which is used to power the standard control system layer when it is awakened when it is determined that the main power supply of the vehicle fails, so as to ensure the stability of the operation of the standard control system layer.

[0044] Furthermore, in an optional implementation of the embodiment of the present application, when the independent power supply configured in the standard control system layer 20 is awakened, the standard control system layer 20 controls the vehicle to be in a power-saving state by controlling the components involved in other peripheral system layers to shut down or reduce power, so as to ensure that the vehicle can still achieve a longer mileage while controlling most of the functions on the vehicle side.

[0045] Optionally, in one implementation of the present invention, when the minimum control system layer 10 is in operation, the control outputs of the basic vehicle functions are distributed to one or more microprocessors, and the multiple microprocessors communicate with each other via CAN / LIN. In this way, the minimum control system 10 does not involve Ethernet services during operation, while ensuring the security and accuracy of vehicle control system communications and further reducing power consumption during vehicle operation.

[0046] Optionally, in one implementation of the present invention, the minimum control system layer 10 can be accessed through both manual switching and automatic switching. Specifically, when the vehicle's standard control system layer 20 generates a notification regarding control failure, the user is prompted and guided to immediately switch control modes to awaken the minimum control system layer 10 to take over control of the vehicle's operation. Alternatively, when the standard control system layer determines that it is unable to effectively control the vehicle's operation, such as when a failure of a key functional component related to the standard control system layer causes the vehicle to enter limp mode, the battery SOC is extremely low, or an OTA upgrade fails, the minimum control system layer 10 is automatically activated and switched to control the vehicle's operation.

[0047] Optionally, in one implementation of an embodiment of the present application, the exit method of the minimum control system layer 10 includes: when the fault of activating the minimum control system layer 10 returns to normal or the vehicle maintenance is completed, the vehicle is powered on and off again, and a judgment is made based on the results of the power on and off to determine whether to exit or switch to the standard control system layer 20 to control the operation of the vehicle.

[0048] In an embodiment of the present application, the standard control system layer 20 is a control system layer that implements the standard functions and platform configuration requirements of the vehicle. The control functions it contains are suitable for the standard configurations of most customers and vehicle models, so as to facilitate the rapid development of projects or vehicle models based on the standard system control layer.

[0049] Optionally, in one implementation of the embodiment of the present application, as Figure 1 As shown, the standard control system layer 20 includes a signal capability interface 201 and a service capability interface 202; the signal capability interface 201 is used for the input and output of different hardware signals of the vehicle and the signal interaction of each function key in the microcontroller, and the service capability interface 202 is used for information interaction between the standard control system layer and the customized system layer or the value-added system layer. Furthermore, the interface of the standard control system layer 20 can be divided into a standard capability interface and an open capability interface according to personalized needs. Among them, the standard capability interface includes, for example: hardware signal input / output. This type of interface is generally not changed to speed up the project development cycle and save development costs. The open capability interface is an interface defined to meet the personalized needs of users. This type of interface does not affect the normal implementation of other functions of the vehicle. It is mostly an application developed on the vehicle side that meets the personalized smart car use needs of users through service calls.

[0050] Optionally, in one implementation of the present invention, the control input of the standard control system layer 20 is real-time data signals from one or more sensors in the first sensor group 201, to meet the input signal collection and processing functions for standard vehicle functions. Specifically, the first sensor group 201 is an extension of the sensor group 101. The control output of the standard control system layer 20 is to control one or more actuators in the first actuator group 202, to meet the output arbitration and control functions for the implementation of standard vehicle functions. Specifically, the first sensor group 201 includes sensors operating under standard vehicle driving conditions, including but not limited to vehicle speed sensors, throttle position sensors, brake position sensors, gear position sensors, power status sensors, steering wheel angle sensors, brake pressure sensors, temperature sensors, onboard cameras, onboard radars, and other sensors commonly installed on vehicles to monitor vehicle operating conditions, to meet the input signal collection and processing functions for the implementation of standard vehicle functions. Its control output is to control the first actuator group 202, including but not limited to operating control parameters of one function among the vehicle's drive motor, engine battery, inverter, brake, steering, air conditioning, or fan.

[0051] Optionally, in one implementation of the present embodiment, the customized system layer 30 and the value-added system layer 40 operate based on the standard control system layer 20 or the minimum control system layer 10. This facilitates the development and expansion of functions associated with the customized system layer 30 or the value-added system layer 40 implemented through the standard control system layer 20, and facilitates the effective management of the developed or expanded functions. Specifically, since the customized system 30 and the value-added system layer 40 do not modify the vehicle's hardware configuration, information exchange between the value-added system layer 40 and the customized system layer 30, between the Zeng Zhihua system layer 40 and the standard control system layer 20, and between the customized system layer 30 and the standard control system layer 20, all occurs through the service capability interface 201 and signal capability interface 202 provided by the standard control system layer 20. These layers are developed based on the standard control system layer 20, with the goal of not modifying the standard control system layer 20 and the minimum control system layer 10. That is, the customized system layer 30 and the value-added system layer 40 rely on the standard control system layer 20 and the minimum control system layer 10 and cannot operate independently. This reduces the difficulty of configuring differentiated customized and value-added systems for different vehicle models. And ensure the rationality of the operation control logic between each layer of the vehicle system.

[0052] Optionally, in one implementation of the embodiment of the present application, the standard control system layer 20 further provides a standardized interface, so that the standard control system layer can simply and reliably perform data transmission with internal and external systems through the standardized interface.

[0053] Optionally, in one implementation of the embodiment of the present application, the value-added system layer 40 adopts an OTA upgrade method, and iteratively upgrades the software of the value-added system layer 40 based on big data analysis and AI analysis of customer usage feedback information, so as to reduce the vehicle model development cycle, provide new functions or the difficulty of performance improvement.

[0054] The present application provides a layered topology of a vehicle's electrical and electronic architecture, including: a minimum control system layer for controlling the basic functions required for the vehicle's driving state; a standard control system layer for covering the vehicle's standard functions and suitable for system configuration in a platform-based configuration method; a customized system layer for providing corresponding vehicle configurations based on customer functional requirements; a value-added system layer for providing diversified software value-added services for the vehicle; and a minimum control system layer for controlling the vehicle's operating state when a failure occurs in the standard control system layer. This vehicle electrical and electronic layered topology, while ensuring the robustness of the entire vehicle, is compatible with the functional requirements for rapid iteration of vehicle functions, can accelerate the development cycle of vehicle models or projects, and can also meet customer needs for personalized and intelligent vehicle use.

[0055] Thus far, this application has described specific embodiments of the present subject matter. Other embodiments are within the scope of the appended claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve the desired results. Furthermore, the processes depicted in the accompanying drawings do not necessarily require the specific order shown or the sequential order to achieve the desired results. In certain embodiments, multitasking and parallel processing may be advantageous.

[0056] In the 1990s, technological improvements could be clearly distinguished as either hardware improvements (for example, improvements to circuit structures like diodes, transistors, and switches) or software improvements (improvements to process flows). However, with the advancement of technology, many process flow improvements today can now be considered direct improvements to hardware circuit structures. Designers almost always create the corresponding hardware circuit structure by programming the improved process flow into the hardware circuit. Therefore, it cannot be said that a process flow improvement cannot be implemented using hardware modules. For example, a programmable logic device (PLD), such as a field programmable gate array (FPGA), is an integrated circuit whose logical function is determined by user programming. Designers can "integrate" a digital system layer onto a PLD through their own programming, eliminating the need for chip manufacturers to design and manufacture dedicated integrated circuit chips. Moreover, nowadays, instead of manually fabricating integrated circuit chips, this programming is mostly done using "logic compiler" software. This is similar to the software compiler used when developing programs. Before compilation, the original code must also be written in a specific programming language, called a hardware description language (HDL). There is not just one HDL, but many, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones are VHDL (Very-High-Speed ​​Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art will also understand that by simply programming the method flow in one of these hardware description languages ​​and then programming it into an integrated circuit, a hardware circuit that implements the logic method flow can be easily obtained.

[0057] The controller can be implemented in any suitable manner. For example, the controller can take the form of a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro)processor, logic gates, switches, application-specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers. Examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art will also know that in addition to implementing the controller in a purely computer-readable program code format, the controller can be implemented in the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontrollers by logically programming the method steps. Therefore, such a controller can be considered a hardware component, and the devices included therein for implementing various functions can also be considered as structures within the hardware component. Or even, the devices for implementing various functions can be considered as both software modules that implement the method and structures within the hardware component.

[0058] The system layers, devices, modules, or units described in the above embodiments may be implemented by computer chips or physical devices, or by products having certain functions. A typical implementation device is a computer. Specifically, the computer may be, for example, a personal computer, a laptop computer, a cellular phone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

[0059] For the convenience of description, the above devices are described as being divided into various units according to their functions. Of course, when implementing this application, the functions of each unit can be implemented in the same or multiple software and / or hardware.

[0060] It should also be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, commodity, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or includes elements inherent to such process, method, commodity, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not exclude the presence of other identical elements in the process, method, commodity, or apparatus that includes the element.

[0061] Those skilled in the art will appreciate that the embodiments of the present application may be provided as methods, system layers, or computer program products. Therefore, the present application may take the form of a complete hardware embodiment, a complete software embodiment, or an embodiment combining software and hardware. Furthermore, the present application may take the form of a computer program product implemented on one or more computer-usable storage media (including but not limited to magnetic disk storage, CD-ROM, optical storage, etc.) containing computer-usable program code.

[0062] The present application may be described in the general context of computer-executable instructions executed by a computer, such as program modules. Generally, program modules include routines, programs, objects, components, data structures, and the like that perform specific tasks or implement specific abstract data types. The present application may also be practiced in distributed computing environments where tasks are performed by remote processing devices connected via a communications network. In a distributed computing environment, program modules may be located in local and remote computer storage media, including storage devices.

[0063] The various embodiments in this specification are described in a progressive manner. Similar parts between the various embodiments can be referred to in conjunction with each other. Each embodiment focuses on the differences between the other embodiments. In particular, the system-level embodiments are generally similar to the method embodiments, so the description is relatively simple. For relevant parts, refer to the description of the method embodiments.

[0064] The above are merely embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
