It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Example 1
Referring to fig. 1 or fig. 2, the present embodiment provides an APP on-screen display method based on dual systems, including:
starting a first operating system, and correspondingly displaying an icon and a name of an APP of the first operating system to an HMI interface of the first operating system;
generating an APP list containing icons and names of the APPs of the second operating system based on the APP information file of the second operating system in the vehicle memory, and correspondingly displaying the icons and names of the APPs in the APP list to an HMI interface of the first operating system;

The dual-system-based APP same-screen display method provided by the application comprises the steps of firstly starting a first operating system, and simultaneously loading an HMI interface running on a first operating system side so as to realize that icons and names of the APP in the first operating system are correspondingly displayed on the HMI interface of the first operating system; then, based on an APP information file of a second operating system in the vehicle memory, APP information is stored in the APP information file, the APP information comprises an icon and a name of the APP, and the icon and the name of the APP of the second operating system are pre-displayed on the same HMI interface; finally, after the second operating system is started, the icon and the name of the second operating system APP in the HMI interface are updated based on the currently installed APP of the second operating system, so that the APP of the two operating systems is finally displayed on the same HMI interface, and the APP of the dual system is conveniently managed, so that convenience of the dual system can be better enjoyed.
The embodiment provides a dual-system-based APP on-screen display method, which starts a first operating system and correspondingly displays an icon and a name of the APP in the first operating system to an HMI interface, including:
acquiring a starting instruction of a user;
starting a first operating system by adjusting the vehicle machine bottom layer resources, and loading an HMI interface;
and correspondingly displaying the icon and the name of the APP in the first operating system to the HMI interface.
In a specific implementation, the first operating system may be a Linux system, and the second operating system may be an Android system. The Linux system is composed of a plurality of microkernels, the source codes of the Linux system are completely open, and the Linux system has very strong network functions and tool chains, not only supports all Internet protocols including TCP/IPv4, TCP/IPv6, link layer topological programs and the like, but also can develop a new protocol stack by utilizing the network characteristics of Unix, and has stronger portability, so that the Linux system is more suitable for the development and operation of HMI interfaces. And the Android system has a huge APP application program, so that a user can conveniently select and install the needed APP, and further user experience is improved.
In addition, because the bottom layer resources of the vehicle and the machine are limited, if two systems are started at the same time, the bottom layer resources are not distributed enough, and the events such as interface blocking and the like are caused, so that when the vehicle and the machine are loaded with the double systems, the two operating systems are started one by one. When a user turns on the vehicle, two operation systems in the vehicle are started with priority, in practical application, the HMI interface for interaction is operated on the side of the Linux system, so that the Linux system can be started with priority, and the HMI interface operated on the side of the Linux system starts to be loaded. After the HMI interface is loaded, a module Linux launch for recording APP information in the Linux system can send icons and names of all the current APPs in the Linux system to the HMI interface for display.
After the first operating system is started, the first operating system generates an APP list containing icons and names of the APPs of the second operating system based on the APP information file of the second operating system in the memory of the vehicle, and the specific method comprises the following steps:
starting a communication agent of a first operating system;
the communication agent of the first operating system acquires an APP information file of the second operating system stored in the memory of the vehicle, and generates an APP list for storing icons and names of the APP in the second operating system based on the APP information file of the second operating system.
The communication agent of the first operating system is enabled to acquire APP information of the second operating system before the second operating system is started, and further icons and names of the APP of the second operating system are pre-displayed on an HMI interface on one side of the first operating system, so that the second operating system is enabled to be started as unobscured as possible.
Further, displaying the icon and name correspondence of the APP in the APP list to the HMI interface, including:
the communication agent of the first operating system sends the APP list to the HMI interface through inter-process communication;
and displaying icons and names of the APP of the second operating system by the HMI interface according to the received APP list.
Still taking a Linux system and an Android system as examples, two operation systems are respectively provided with a communication agent, and the communication agents are used for communication between the systems and communication between the operation systems and bottom resources such as a vehicle memory, wherein the communication agent of a first operation system is Linux gateway, and the communication agent of a second operation system is Android gateway. When the Linux system is started and the Android system is not started yet, the Linux system side can read and process the APP information files of the Android system, which are reserved in the local memory of the vehicle machine when the vehicle is started last time, by utilizing a communication agent Linux gateway, sort and generate the information of icons, names and the like of the APPs in the Android system, generate an APP list, send the APP list to the HMI interface through interprocess communication, correspondingly display the icons and the names of the APPs in the APP list on the HMI interface, and pre-display the icons and the names of the APPs in the second operating system on the same HMI interface of the first operating system before the second operating system is started.
After the second operating system is started, the APP list is updated based on the currently installed APP of the second operating system, and the specific method comprises the following steps:
starting a second operating system and a communication proxy of the second operating system;
the communication agent of the second operating system acquires the currently installed APP information of the second operating system from the packet management service of the second operating system through interprocess communication, and synchronously arranges the currently installed APP information to generate an APP information list, wherein the APP information list comprises icons and names of all APPs currently installed by the second operating system;
the communication agent of the second operating system transmits the APP information list to the communication agent of the first operating system through inter-system communication;
and the communication agent of the first operating system updates the APP list according to the APP information list so that the icons and names of the APPs in the updated APP list are consistent with the icons and names of the APPs in the APP information list. The method ensures that the icons and names of the APPs in the APP list are consistent with the icons and names of the APPs installed in the second operating system as much as possible.
Wherein updating the APP list according to the APP information list comprises at least one of:
deleting icons and names of the APP which are not in the APP information list from the APP list;
adding icons and names of the APPs which exist in the APP information list but do not exist in the APP list to the APP list;
checking whether icons and names of the APPs existing in the APP list and the APP information list are consistent, and replacing icons and/or names inconsistent with the APP information list in the APP list with corresponding icons and/or names in the APP information list.
In a specific implementation, taking a Linux system and an Android system as an example, a from work is a managed execution environment in which an application running in the Android system provides various services, where the from work includes a packet management service Package Manager Service and an APP event management module Linux Open APP Manager, APP information of the Android system is stored in the packet management service Package Manager Service, and the APP event management module may collect the APP information from the packet management service Package Manager Service and send the collected APP information to a communication agent Android gateway of the Android system through inter-process communication.
After the Android system is started, the Android gateway of the communication agent of the Android system acquires APP information from the packet management service Package Manager Service through the APP event management module Linux Open APP Manager, and synchronously organizes the latest APP information to generate an APP information list, after the Android gateway of the communication agent of the Android system acquires the APP information list, the Android gateway of the communication agent of the Android system transmits the APP information list to the Linux gateway of the communication agent of the Linux system through inter-system communication, and the Linux gateway updates the APP list for storing icons and names of the APPs in the second operating system according to the latest APP information list provided by the Android system, so that the icons and names of the APPs currently installed in the second operating system are stored in the APP list, and consistency of the APP information is ensured.
Further, the updated APP list is sent to the HMI interface through inter-process communication, and the icon and the name of the second operating system APP in the HMI interface are corrected and updated based on the updated APP list, and the specific method comprises the following steps:
the communication agent of the first operating system sends the updated APP list to the HMI interface through inter-process communication;
the HMI interface corrects and updates the currently displayed icons and names of the APPs of the second operating system according to the received updated APP list, so that the icons and names of the APPs of the second operating system displayed on the HMI interface are consistent with the updated icons and names of the APPs in the APP list, and further the icons and names of the APPs of the second operating system displayed on the HMI interface are consistent with the currently installed icons and names of the APPs of the second operating system, so that the APP operation faults are avoided.
The method for correcting and updating the icons and names of the currently displayed APP of the second operating system by the HMI interface according to the received updated APP list comprises at least one of the following steps:
deleting icons and names of the APPs which are not in the updated APP list from the HMI interface;
adding the icons and names of the APPs which exist in the updated APP list but do not exist in the HMI interface to the HMI interface;
checking whether icons and names of the APPs existing in the HMI interface and the updated APP list are consistent, and replacing icons and/or names inconsistent with the updated APP list in the HMI interface with corresponding icons and/or names in the updated APP list.
The HMI interface performs updating operations such as adding, deleting, changing and the like on the display of the APP icons and names according to the latest APP list so as to ensure that the icons and names of the APP displayed on the HMI interface are corresponding and consistent with the icons and names of the APP currently installed in the second operating system, and further ensure good use feeling of the user.
In addition, in the dual-system-based APP on-screen display method provided by the embodiment, as can be seen from fig. 2, in the architecture applied by the scheme of the present application, a desktop management module is not required to be set on one side of the second operating system, and further, cooperative processing is not required to be added between the desktop management module of the first operating system and the desktop management module of the second operating system, so that APPs of the two operating systems can be displayed in the same HMI interface, which is simple, convenient and fast; meanwhile, as the desktop management module is not required to be arranged at one side of the second operating system, the communication problem between the desktop management module and the first operating system and/or the HMI interface is not required to be considered, the requirements for functions such as communication capacity at one side of the second operating system are reduced, communication between the two operating systems can be realized by utilizing the universal modules such as a gateway and the like, and APP of the second operating system is displayed on the HMI interface of the first operating system, so that the system construction cost is saved.
In the implementation, taking the first operating system as a Linux system and taking the second operating system as an Android system as an example, since the Android system side does not need to perform desktop management to directly communicate with an HMI interface, the Android system is not required to be arranged, desktop management is performed only through the Linux system side, and then APP of the two operating systems is displayed in the same HMI interface based on communication between the two operating systems. The implementation mode has the advantages that if the Android system side is also provided with a desktop manager for desktop management, the desktop management is needed by both operating systems, and cooperative processing operation is additionally needed between the desktop management on two sides, so that the complexity of data processing is increased; in addition, as known by those skilled in the art, the native launcher of the Android system does not have a communication function, if the native launcher of the Android system is required to communicate with the Linux system directly to perform desktop management, the function requirement on the native launcher of the Android system is relatively high, the native launcher of the Android system is required to be functionally improved to support communication between the Android system and the Linux system, and the workload and cost of research and development personnel are increased.
In addition, the dual-system-based APP same-screen display method provided by the embodiment further comprises the following steps:
deleting an APP information file of a second operating system in the memory of the vehicle;
and converting the format of the updated APP list, generating a new APP information file of the second operating system, and storing the APP information file into the memory of the vehicle.
Specifically, deleting an APP information file of a second operating system in the vehicle memory through a communication agent of the first operating system, converting the format of the updated APP list through the communication agent of the first operating system, generating a new APP information file of the second operating system, and storing the new APP information file into the vehicle memory. Taking Linux system and Android system as examples, after the updated APP list is sent out, the APP information file of the Android system which is locally reserved is deleted, and then the updated APP list is made into the APP information file of the Android system in json format to be stored in the local memory of the vehicle, so that APP information of the Android system (second operating system) which is acquired when the vehicle is restarted is as latest as possible, the operations of adding, deleting and modifying icons and names of the APP of the second operating system in an HMI interface are reduced, and the use experience of a user is further improved.
