The present application is described below based on examples, but the present application is not limited to only these examples. In the following detailed description of the present application, certain specific details are set forth in detail. The present application will be fully understood by those skilled in the art without the details described herein. Well-known methods, procedures, flows, components and circuits have not been described in detail so as not to obscure the nature of the application.
Moreover, those of ordinary skill in the art will appreciate that the drawings are provided herein for illustrative purposes and that the drawings are not necessarily drawn to scale.
Unless the context clearly requires otherwise, the words "comprise," comprising, "and the like throughout the specification are to be construed as including, rather than being exclusive or exhaustive, that is to say, as" including but not limited to.
In the description of the present application, it should be understood that the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance. Furthermore, in the description of the present application, unless otherwise indicated, the meaning of "a plurality" is two or more.
The schemes described in the present specification and embodiments, if related to personal information processing, all perform processing on the premise of having a validity base (for example, obtaining agreement of a personal information body, or being necessary for executing a contract, etc.), and perform processing only within a prescribed or agreed range. The user refuses to process the personal information except the necessary information of the basic function, and the basic function is not influenced by the user.
In the following description, a vehicle control system will be described as an example, but it should be understood that the solution according to the embodiments of the present application is also applicable to control systems of other types of machine devices, such as unmanned vehicle control systems or aircraft control systems, etc., and the present application is not limited thereto.
Fig. 1 is a schematic diagram of a control system according to an embodiment of the invention. As shown in fig. 1, the control system comprises a central control unit 11 and at least one domain controller 12.
Wherein the central control unit 11 is a hardware device for receiving and processing user requests. In this embodiment, the central control unit 11 is connected to each domain controller 12, and the central control unit 11 is configured to instruct, when a user request is detected, the corresponding domain controller 12 to respond to the user request to provide a corresponding service to the user.
It should be appreciated that the central control unit 11 may be present in the control system as a separate control device or may be integrated in a corresponding domain controller, as the application is not limited in this regard. In order to be able to receive the user request and to feed back the result of the request processing to the user, the central control unit 11 may be connected to a corresponding input/output device, such as a touch screen or the like. Meanwhile, in order to process the user request in time, the central control unit 11 may be started in a hot start manner to avoid the process of re-powering.
The domain controller 12 is a processor hardware platform for providing a plurality of vehicle functions, and at least one electronic controller unit is integrated into the domain controller 12, each of the electronic controller units being operable to provide at least one vehicle function. In the present embodiment, the domain controller 12 may control the corresponding electronic controller unit to provide the corresponding vehicle function under the direction of the central control unit 11 to provide the service to the user.
It should be understood that in order to be able to provide vehicle functions, each of said electronic controller units should also be connected to a respective actuator (e.g. power windows, air conditioning, car lights, and audio, etc.) or sensor (e.g. radar sensor, speed sensor, acceleration sensor, etc.).
Further, since the integrated domain controller is too complex, in order to ensure that the domain controller can operate normally, each domain controller 12 typically includes two parts, namely a System on Chip (SoC) and a micro control unit (Micro Control Unit, MCU).
Among them, since the performance of the system on chip is stronger than that of the micro control unit, the related art generally uses the system on chip as a carrier of a service program to make the system on chip provide services for users by running an internally deployed service program. However, in the initial power-up stage, the domain controller is usually started by a cold start mode when the domain controller is started, that is, the micro control unit is started first and then the corresponding system on chip is started through the micro control unit, which makes it take a long time for the related art system on chip to be successfully started, and the domain controller cannot provide services for the user before the system on chip is not successfully started.
In this embodiment, the service program related to the user experience is deployed in the micro control unit in advance, and then when the central control unit 11 detects that the service acquisition request is triggered, the target system-on-chip of the target domain controller or the target micro control unit responds to the service acquisition request according to the system start state of the target system-on-chip of the corresponding target domain controller.
Therefore, the embodiment can respond to the service acquisition request without waiting for the successful start of the target system on chip, thereby solving the problem that the domain controller service is not available due to low start speed of the system on chip in the initial power-on stage, and further ensuring the user experience.
Meanwhile, since the micro control unit is usually in an idle state in the initial power-on stage, the service program is deployed in the micro control unit, so that the micro control unit can replace a system-on-chip to provide service for a user before the system-on-chip is successfully started, and the utilization efficiency of the micro control unit can be improved.
Alternatively, the central control unit 11 and each domain controller 12 may be connected through an ethernet. The domain controllers 12 and the electronic controller units may be connected by a CAN bus (Controller Area Network, controller area network bus), flexRay bus, or LIN bus (Local Interconnect Network ). Thus, data interaction of the vehicle system can be achieved.
Fig. 2 is a flowchart of a control method according to an embodiment of the present invention. As shown in fig. 2, the control method specifically may include the following steps:
it should be understood that the execution subject of the control method may specifically be the central control unit in the above-described embodiment.
S100, detecting a system start state of the target system-on-chip in response to detecting that the service acquisition request is triggered.
Specifically, the central control unit may determine a target domain controller corresponding to a service acquisition request and detect a system start state of a target system on chip of the target domain controller when detecting that the service acquisition request is triggered.
It should be appreciated that the overall vehicle architecture can be generally divided into a cabin domain, a body domain, an autopilot domain, a power domain, and a chassis domain according to the electronic-electrical architecture of the existing vehicle. Accordingly, the domain controllers of the vehicle may include cabin domain controllers, body domain controllers, autopilot domain controllers, power domain controllers, and chassis domain controllers, among others. The cabin domain controller is used for controlling various electronic information systems (such as a central control system, a vehicle-mounted infotainment system, a head-up display system, a seat system, an instrument system, a rearview mirror system, a driving behavior monitoring system, a navigation system and the like) in the intelligent cabin. The body area controller is used for controlling various electronic devices (such as car lights, car doors, car windows, sunroofs, windscreen wipers, air conditioners, antennas, gateway communication and the like) on the car body. The autopilot domain controller is configured to implement and control autopilot functions of the vehicle. The power domain controller is an intelligent power assembly management unit, and the functions of the power domain controller include, but are not limited to, engine management, gearbox management, battery management, power distribution management, emission management, speed limit management, oil saving and electricity saving management and the like. The chassis domain controller is used for controlling the running behavior and running posture of the vehicle, and the functions of the chassis domain controller include, but are not limited to, brake system management, vehicle transmission system management, running system management, steering system management, vehicle speed sensor management, vehicle body posture sensor management, air suspension system management, airbag system management and the like. In step S100, the central control unit may determine a target domain controller among the cabin domain controller, the body domain controller, the autopilot domain controller, the power domain controller, and the chassis domain controller according to the current service acquisition request. For example, if the current service acquisition request is to turn on the air conditioner, the central control unit may determine a body domain controller for managing each electronic device on the body as a target domain controller.
It should be understood that the above-mentioned control domain division manner is only given for illustration, and in the actual application process, the control domain may be divided in other manners due to the expansion of the service or the difference of the applied machine equipment, but the central control unit may determine the target domain controller from the corresponding domain controllers according to the current service acquisition request.
It should be appreciated that, since some services may need to be implemented by multiple domain controllers in cooperation, the number of target domain controllers determined by the central control unit may be one or more.
And S200, indicating the target system-on-chip or the target micro control unit to respond to the service acquisition request according to the system start state.
Specifically, after detecting the system start state of the target system on chip, the central control unit may instruct the target system on chip or the target micro control unit of the target domain controller to respond to the service acquisition request according to the system start state.
Optionally, since the system on chip generally feeds back a service available message to the central control unit after successful start, when detecting a service acquisition request, the central control unit may determine a system start state of the target system on chip by detecting whether the service available message sent by the target system on chip is received. Specifically, if a service available message sent by the target system-on-chip is received, the central control unit may determine that the target system-on-chip is in a successful start state. Or if the service available message sent by the target system-on-chip is not received, the central control unit can determine that the target system-on-chip is in an unsuccessful starting state.
Alternatively, the central control unit may instruct the target micro-control unit to respond to the service acquisition request when the target system-on-chip is in an unsuccessful start state. Or the central control unit may instruct the target system-on-chip to respond to the service acquisition request when the target system-on-chip is in a successful start-up state.
Alternatively, in order to enable successful communication with the target micro control unit and the target system on chip, the central control unit may have a first program and a second program deployed therein. The central control unit may evoke the first and second programs during an initial power-up phase. The first program is used for realizing data communication with the target micro-control unit, and the second program is used for realizing data communication with the target system-on-chip. Further, when the target system-on-chip is in an unsuccessful start state, the central control unit may instruct the target micro control unit to respond to the service acquisition request through the first program. Or when the target system-on-chip is in a successful start state, the central control unit can instruct the target system-on-chip to respond to the service acquisition request through the second program. Correspondingly, a first response program for responding to the first program is also deployed in the target micro-control unit, and a second response program for responding to the second program is also deployed in the target system-on-chip.
Further, SOME/IP protocol stack (Scalable service-Oriented MiddlewarE over IP, internet protocol-based extensible service-oriented communication middleware) may be employed for communication between the first program and the first response program and between the second program and the second response program. Wherein the SOME/IP protocol stack is a service-oriented in-vehicle Ethernet communication protocol, which may be used for different physical layer networks including Ethernet, CAN, flexRay, etc., with the objective of providing interoperability between these networks.
Optionally, in order to save the memory space of the central control unit, the central control unit may further stop running the first program after detecting that the target system-on-chip is in a successful start state.
Optionally, the target system-on-chip or the target micro-control unit may control the corresponding electronic controller unit to provide the corresponding service according to the service acquisition request under the instruction of the central control unit.
Fig. 3 is a schematic diagram of a control system according to an embodiment of the present invention. As shown in fig. 3, the control system includes a central control unit 31 and a target domain controller 32. The central control unit 31 includes an application layer 311, an application framework layer 312, and a local service layer 313.
The Application layer 311 includes at least one Application (APP). In this embodiment, the user may trigger a corresponding service acquisition request through each of the application programs.
The application framework layer 312 includes at least one vehicle service component therein. In this embodiment, each of the vehicle service components is configured to maintain a service state of a corresponding vehicle service, where the service state may provide service support to an application program, may communicate a downward call of the application program with each service program in the local service layer 313, or may be configured to receive an up-to-date state of the corresponding vehicle service and notify the up-to-date state to a corresponding application program in time.
The local service layer 313 includes a proxy service, which is a Native process for maintaining at least one service program. In the present embodiment, the proxy service is used to maintain a service program related to user experience deployed in the central control unit 31.
Further, in the present embodiment, the service program deployed at the central control unit 31 may include a first program, a second program, and a selection program. The first program is used for communicating with a first response program in the target micro control unit 322, the second program is used for communicating with a second response program in the target system-on-chip 321, and the selection program is used for detecting a system start state of the target system-on-chip 321 and indicating the first program to communicate with the first response program or indicating the second program to communicate with the second response program according to the system start state so as to enable the target micro control unit 322 or the target system-on-chip 321 to respond to the service acquisition request.
Specifically, in the actual application process, after the central control unit is started, the first program and the second program are called and the first program and the second program complete corresponding service identifier binding operation and service subscription operation. When an application detects that a user triggers a service acquisition request, a vehicle service component corresponding to the service acquisition request communicates the service acquisition request to a selection program corresponding to the service acquisition request. The selection program may detect a system start state of the target system on chip 321 of the target domain controller corresponding to the service acquisition request, and communicate with a first response program in the target micro control unit 322 or instruct a corresponding second program to communicate with a second response program in the target system on chip 321 according to the first program indicated by the system start state, so that the target micro control unit 322 or the target system on chip 321 responds to the service acquisition request. It should be appreciated that the service identities of the first program and the second program corresponding to the same service program may be different.
Alternatively, the application and the vehicle service component may communicate via a Binder. Wherein the Binder is a mechanism for cross-process communication that allows components in one process to communicate with components in another process to enable inter-process communication. The vehicle service components and the service programs in the local service layer 313 may communicate via HAL (Hardware Abstraction Layer ). The first program and the second program in the local service layer 313 and the first response program in the target micro control unit 322 and the second response program in the target system on chip 321 may use a SOME/IP protocol stack to communicate.
When the control method of the embodiment of the invention detects that the service acquisition request is triggered, detecting the system starting state of the target system on chip of the target domain controller corresponding to the service acquisition request, and indicating the target system on chip or the target micro control unit of the target domain controller to respond to the service acquisition request according to the system starting state. Therefore, the target system-on-chip or the target micro-control unit is instructed to respond to the service acquisition request according to the system start state of the target system-on-chip, and the embodiment can respond to the service acquisition request without waiting for the successful start of the target system-on-chip, so that the problem that the domain controller service is unavailable due to low start speed of the system-on-chip in the initial power-on stage is solved, and user experience is further ensured.
Fig. 4 is a schematic diagram of a control device according to an embodiment of the invention. As shown in fig. 4, the control device of the embodiment of the present invention includes a detection unit 41 and an indication unit 42.
Specifically, the detecting unit 41 is configured to detect, in response to detecting that a service acquisition request is triggered, a system start state of a target system on chip, where the target system on chip is a system on chip of a target domain controller, and the target domain controller is a domain controller corresponding to the service acquisition request;
the indicating unit 42 is configured to indicate, according to the system start state, the target system on chip or a target micro control unit to respond to the service acquisition request, where the target micro control unit is a micro control unit of the target domain controller.
When detecting that the service acquisition request is triggered, the control device of the embodiment of the invention detects the system start state of the target system on chip of the target domain controller corresponding to the service acquisition request, and then indicates the target system on chip or the target micro control unit of the target domain controller to respond to the service acquisition request according to the system start state. Therefore, the target system-on-chip or the target micro-control unit is instructed to respond to the service acquisition request according to the system start state of the target system-on-chip, and the embodiment can respond to the service acquisition request without waiting for the successful start of the target system-on-chip, so that the problem that the domain controller service is unavailable due to low start speed of the system-on-chip in the initial power-on stage is solved, and user experience is further ensured.

Thus, the processor 51 performs the process of the embodiment of the present invention as described above to realize the processing of data and the control of other devices by executing the instructions stored in the memory 52. The bus 53 connects the above-described components together, and connects the above-described components to the display controller 54 and the display device and the input/output (I/O) device 55.
