Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of intelligent transportation vehicles, and in particular to a method for implementing an intelligent cockpit, an intelligent cockpit, and a computer-readable medium. Background Art

[0002] Currently, civilian cars are developing towards electrification, networking, intelligence and sharing. The smart cockpit of a car needs to provide not only digital instruments and on-board controls, but also rich entertainment functions.

[0003] Automotive electrical and electronic architecture is also evolving from a traditional distributed architecture to a regional centralized architecture, ultimately developing into a centralized architecture. A characteristic of the regional centralized architecture is that it integrates the computing power previously dispersed across multiple electronic control units (ECUs) and microcontrollers (MCUs) within a domain onto a large regional computing platform, known as the domain master processor. Currently, the entire vehicle can be divided into the powertrain domain, chassis domain, body / comfort domain, cockpit / infotainment domain, and autonomous driving domain based on specific functional domains.

[0004] The current approach to implementing smart cockpits in cars either results in bloated and complex cockpits or creates a large computational resource overhead for the entire system. Summary of the Invention

[0005] Embodiments of the present application provide a method for implementing a smart cockpit, a smart cockpit, and a computer-readable medium.

[0006] In a first aspect, an embodiment of the present application provides a method for implementing a smart cockpit, comprising: implementing basic functions through a microkernel operating system of a microkernel layer; wherein the basic functions include: functions that are necessary for the operation of the microkernel operating system; under the control of the microkernel operating system, implementing additional functions through the system area of ​​the microkernel application layer, and allocating exclusive computing resources to each safety-critical business; wherein the additional functions include: auxiliary functions required for the operation of the microkernel operating system; under the control of the microkernel operating system, implementing safety-critical businesses through the application area of ​​the microkernel application layer; under the control of the microkernel operating system, implementing non-safety-critical businesses through the virtual area of ​​the microkernel application layer.

[0007] In a second aspect, an embodiment of the present application provides an electronic device, comprising: at least one processor; a memory, wherein at least one program is stored in the memory, and when the at least one program is executed by the at least one processor, any one of the above-mentioned smart cockpit implementation methods is implemented.

[0008] In a third aspect, an embodiment of the present application provides a computer-readable medium having a computer program stored thereon. When the computer program is executed by a processor, any one of the above-mentioned methods for implementing a smart cockpit is implemented.

[0009] The implementation method of the smart cockpit provided in the embodiment of the present application runs an operating system on a set of hardware devices, and implements all the functions of the smart cockpit in one operating system. It does not require excessive computing resource overhead and is relatively simple to implement. By using microkernel technology in the operating system, security-critical services can be hosted in the application area of ​​the microkernel application layer, which is currently impossible for systems such as Linux. The scalability is relatively good, and for new functions, it is only necessary to divide the new functions into security-critical services and non-security-critical services, and add the new functions in the areas where the security-critical services or non-security-critical services are located.

[0020] Figure 1 A flowchart of a method for implementing a smart cockpit provided in one embodiment of the present application.

[0021] First, refer to Figure 1 One embodiment of the present application provides a method for implementing a smart cockpit, including:

[0022] Step 100, such as Figure 2 As shown, the basic functions are realized by the microkernel operating system of the microkernel layer; wherein the basic functions include: functions that are necessary for the operation of the microkernel operating system.

[0023] In some exemplary embodiments, the basic functions include: a process management function, a capability execution function, an interrupt management function, an exception handling function, and an inter-process communication function.

[0024] In some exemplary embodiments, the functional safety of the microkernel operating system complies with ISO 26262-6:2011, Road vehicles — Functional safety — Part 6: Software-layer product development.

[0025] Step 101, as Figure 2 As shown, under the control of the microkernel operating system, additional functions are implemented through the system area of ​​the microkernel application layer, and exclusive computing resources are allocated to each security-critical business; wherein the additional functions include: auxiliary functions required for the operation of the microkernel operating system.

[0026] In some exemplary embodiments, the additional functions include: hardware abstraction functions, basic middleware, and system service functions.

[0027] In some exemplary embodiments, the hardware abstraction function includes at least one of the following: a device driver, a file system, a network protocol stack, and the like.

[0028] In some exemplary embodiments, the basic middleware includes at least one of the following: a C or C++ program runtime environment, a system interface library, and the like.

[0029] In some exemplary embodiments, the system service function includes at least one of the following: a resource management service function, a system monitoring service function, and the like.

[0030] In some exemplary embodiments, the system service function is implemented through an independent process space of the system area.

[0031] In some exemplary embodiments, the computing resources include at least one of the following: CPU resources, memory resources, and cache resources.

[0032] In some exemplary embodiments, the computing resources allocated to the safety-critical business are exclusive resources of the safety-critical business and have exclusive usage rights.

[0033] The embodiment of the present invention only implements simple basic functions in the microkernel layer, and complex additional functions are moved to the system area of ​​the microkernel application layer. The system service functions are implemented in an independent process space. Such a decentralized design makes the software system architecture robust to runtime errors, which means that a failure within the process corresponding to a system service function will not affect other processes and the kernel, ensuring the reliable operation of the kernel and security-critical services.

[0034] Step 102, as Figure 2 As shown, under the control of the microkernel operating system, security-critical services are implemented through the application area of ​​the microkernel application layer.

[0035] In some exemplary embodiments, the safety-critical service is a service that requires real-time performance or safety.

[0036] In some exemplary embodiments, safety-critical services include at least one of the following: services requiring real-time performance, services requiring functional safety, services requiring startup time, and services requiring information security. For example, in the smart cockpit field, safety-critical services include at least one of the following: instrument monitoring services and assisted driving monitoring services.

[0037] The functional safety of the instrument monitoring and assisted driving monitoring services implemented in the smart cockpit complies with ISO26262-6:2011, Road vehicles — Functional safety — Part 6: Software layer product development.

[0038] Step 103, as Figure 2 As shown, under the control of the microkernel operating system, non-safety-critical services are implemented through the virtual area of ​​the microkernel application layer.

[0039] In some exemplary embodiments, the application area, the system area, and the virtual area are each composed of a group of processes, divided according to business types, and implemented using the process management function provided in the microkernel operating system.

[0040] In some exemplary embodiments, non-safety-critical services are services that have no requirements for real-time performance and safety.

[0041] In some exemplary embodiments, the non-safety-critical service includes at least one of the following: a digital instrument service, an infotainment service, an assisted driving service, and the like.

[0042] In some exemplary embodiments, Figure 2 As shown, under the control of the microkernel operating system, the non-safety-critical business is realized through the virtual area of ​​the microkernel application layer, including: under the control of the microkernel operating system, the virtual machine manager in the virtual area is used to manage the virtual machines in the virtual area; and the non-safety-critical business is realized through the main virtual machine in the virtual area.

Specifically, Linux container technology is used within the primary VM to isolate the Linux environment of the primary VM into at least one relatively independent execution space. Leveraging Linux's rich software ecosystem, different non-safety-critical services are implemented within different execution spaces. Because the execution spaces are isolated, the quality of service of each execution environment can be well guaranteed.

[0049] In some exemplary embodiments, a primary virtual machine is used to provide virtualization services for detection hardware devices and systems for non-safety-critical businesses, so that non-safety-critical businesses can use these detection hardware devices and systems simultaneously and work normally.

[0052] In some exemplary embodiments, the system further includes: dividing the shared memory space into at least two subspaces through a microkernel operating system. The at least two subspaces can be allocated to different services to enable communication and interaction between the services. For example, the shared memory space is divided into subspace 1 and subspace 2. Subspace 1 is allocated to the assisted driving service and the assisted driving monitoring service, which use subspace 1 for communication and interaction; subspace 2 is allocated to the digital instrument service and the instrument monitoring service, which use subspace 2 for communication and interaction.

[0054] In some exemplary embodiments, the first hardware module includes: a central processing unit (CPU), an interrupt, a memory, and the like.

[0055] In some exemplary embodiments, the CPU is a high-computing-power CPU.

[0056] In some exemplary embodiments, all modules in the hardware device comply with International Standardization Organization (ISO) 26262-6:2011, Road vehicles — Functional safety — Part 5: Hardware-layer product development, and chip manufacturing complies with AEC-Q100 requirements.

[0057] In some exemplary embodiments, the second hardware module includes: a debugging module, a memory, and a network module.

[0061] In some exemplary embodiments, the hardware modules with independent computing capabilities include: a graphics processing unit (GPU) and an embedded neural network processor (NPU).

[0062] In some exemplary embodiments, the GPU is a high-performance GPU.

[0063] In some exemplary embodiments, under the control of the microkernel operating system, managing and using the third hardware module in the hardware device through the virtual area of ​​the microkernel application layer includes: under the control of the microkernel operating system, managing the virtual machines in the virtual area through the virtual machine manager in the virtual area; and managing and using the third hardware module in the hardware device through the main virtual machine in the virtual area.

[0064] The following describes the startup process of the smart cockpit software system, such as Figure 3As shown, after the hardware device is powered on, it performs a hardware self-test and boots the micro-kernel operating system from the memory.

[0065] The microkernel operating system initializes the first hardware modules such as interrupts and memory, starts the root process, and then initializes the entire system area.

It does not require excessive computing resource overhead and is relatively simple to implement. By using microkernel technology in the operating system, security-critical services can be hosted in the application area of ​​the microkernel application layer, which is currently impossible for systems such as Linux. The scalability is relatively good, and for new functions, it is only necessary to divide the new functions into security-critical services and non-security-critical services, and add the new functions in the areas where the security-critical services or non-security-critical services are located.
