Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
Referring to fig. 1, fig. 1 exemplarily shows main steps of a vehicle user data sharing method in the present embodiment. As shown in fig. 1, the method for sharing data of a vehicle user in this embodiment includes the following steps:
step S101: and controlling the vehicle machine APP corresponding to the current login user of the vehicle machine to call account services corresponding to the vehicle machine APP in advance in the operating system.
In this embodiment, the vehicle machine may be a control system capable of implementing a specific function, and in some cases, may directly refer to a controller of the control system. It should be noted that the scope of the present invention is not limited to this specific embodiment. Without departing from the principle of the present invention, it should be clear to those skilled in the art that the vehicle machine may be an in-vehicle entertainment display system, an in-vehicle central control system, an in-vehicle computer system, etc., and these modifications or alternatives fall within the scope of the present invention.
In this embodiment, the in-vehicle user data sharing method is applied to an operating system based on a Linux kernel, which is an open source system. The Android operating system is an operating system constructed on the basis of a Linux kernel, and for simplicity of explanation, the Android operating system is taken as an example for explanation in the embodiment of the invention.
In practical application, the car machine APP runs in an Android operating system of a car machine, each car machine APP can generate a corresponding process in the Android operating system during running, and the highest authority of the car machine APP process is a system process. The Android operating system is constructed on the basis of a Linux kernel, a Linux sandbox still exists in the Android operating system, different users belong to different user groups due to the limitation of the Linux sandbox, and a vehicle machine APP process without system authority cannot access a directory and a file with the system authority, wherein the sandbox is an isolated running mechanism of a program and aims to limit the access authority when an untrusted process or an untrusted code runs. In addition, after the car machine switches the login user, the car machine APP can start a new process, then the car machine APP process of the background user is killed, and the new car machine APP process cannot access the data of the car machine APP process of the original user.
Specifically, in order to realize data sharing, after the Android operating System runs, a corresponding System account service can be established for each vehicle machine APP in the System Server, the vehicle machine APP can acquire the account System service through the account service, and the vehicle machine APP can also directly acquire the corresponding account System service to execute subsequent operations. The account System service is a service process which runs in a System Server and has certain authority.
The System Server is a provider of Android basic services and is the most basic requirement for the operation of an Android System, all services are operated in a process called the System Server, and the System Server process is the first virtual machine process inoculated after a Zygote process of the Android operating System is started. The last login user is a master user, the current login user is a non-master user for example, and the vehicle machine APP corresponding to the non-master user can access data of the master user running in the account system service through the account service, so that the new vehicle machine APP process can access the data of the vehicle machine APP process of the original user. The account System service can be a System service corresponding to a preset master user in an Android operating System, and is also pre-constructed by a System Server, and the master user can be a vehicle owner.
Step S102: and controlling the vehicle APP to call account system services added in advance in the operating system according to the account system services.
The account System service runs in the System Server, after users are switched, the account System service cannot be killed, and the vehicle-mounted APP processes corresponding to different users can access data of the master user through the account System service. Specifically, for example, the car APP is used as the display electric quantity information APP, the display electric quantity information APP corresponding to the currently logged-in user can access history information of battery electric quantity use in the storage space of the master user through the account system service, and the display electric quantity information APP corresponding to the next logged-in user can also access history information of battery electric quantity use in the storage space of the master user through the account system service.
The vehicle machine APP processes corresponding to different users can store and/or acquire shared data through an open interface of the account system service, and the account system service can control access permissions of the vehicle machine APP corresponding to the users.
Step S103: and the account system service judges whether the vehicle APP has the access right, and if so, the step S104 is executed.
In practical application, in order to ensure that the requirement of the vehicle machine on data security can be met while data sharing is carried out between different users, an access permission can be allocated to the vehicle machine APP through the account system service or the access of the vehicle machine APP is prohibited, before the vehicle machine APP stores and/or acquires shared data in a database, the account system service can judge whether the vehicle machine APP has the access permission, and if the vehicle machine APP has the access permission, the step S104 can be executed.
Specifically, whether the car-in-device APP has the access right or not can be judged by identifying the UID/PID of the car-in-device APP process, wherein the Android operating system allocates different UIDs (User Identification ) to each User, and which User runs the current car-in-device APP can be determined specifically according to the UID; the PID (Process Identification) is an identity of a vehicle-mounted machine APP Process, the Android operating system allocates a unique PID to each vehicle-mounted machine APP Process, the account system service can determine which user runs the current vehicle-mounted machine APP specifically according to the UID, whether the PID of the vehicle-mounted machine APP Process is in an authority list preset by the account system service is judged, and if the PID of the vehicle-mounted machine APP Process is in the authority list, the vehicle-mounted machine APP Process has access authority. Therefore, the account system service can judge whether the vehicle-machine APP processes corresponding to different users have access rights according to the UID/PID corresponding to the vehicle-machine APP processes. Therefore, the account system service can judge whether the vehicle-machine APP processes corresponding to different users have access rights according to the UID/PID corresponding to the vehicle-machine APP processes. Specifically, taking the users UID as 1, 2 and 3, and the car APP processes PID corresponding to each user as 4, 5 and 6 as examples, if UID/PID is 1/4 in the authority list preset by the account system service, it indicates that the car APP process with PID being 4 corresponding to the user UID being 1 has the authority to access the account system service.
Step S104: and storing and/or acquiring shared data in a system process database which is pre-constructed in an operating system according to the account system service.
In practical application, a system process database can be constructed in an operating system in advance, wherein the system process database is constructed in a storage space corresponding to a master user, data of vehicle machine APPs corresponding to different users can be stored in the system process database, the system process database has access authority limitation, and only the vehicle machine APP process with system authority can access the system process database. Optionally, in this embodiment, the car APP process that sets UID to system can access the system process database.
In practical application, an ID number may be allocated to the car-machine registered user, where an ID number user _ ID may be allocated to a primary user as 0, and an ID number user _ ID may be allocated to an i-th non-primary user as i + 9.
The following describes, with reference to fig. 2, the in-vehicle multi-user Data sharing method provided by the present invention, by taking a non-master user with a master user and a user _ id of 10, a car-machine APP as a navigation APP and a music APP, and a system process database as a Data Provider database as examples.
Referring to fig. 2, fig. 2 schematically shows a schematic block diagram of a data sharing method for a vehicle user in the present embodiment. As shown in fig. 2, the method for sharing data of a vehicle user in this embodiment mainly includes the following steps:
the navigation APP and the music APP corresponding to the main user and the navigation APP and the music APP corresponding to the non-main user with user _ id of 10 can both store and/or acquire shared Data from the Data Provider database through account system service. The shared data may include vehicle body characteristic data of a vehicle corresponding to the vehicle machine, and/or vehicle driving data, and/or vehicle-mounted device operation data, specifically, the vehicle body characteristic data may include a color of the vehicle, a height of the vehicle, vehicle length data, and the like; the vehicle driving data can comprise the residual battery capacity of the vehicle, the driving mileage of the vehicle and the like; the vehicle-mounted device operation data can comprise a vehicle-mounted device gesture unlocking password and the like.
By the vehicle-mounted device user data sharing method, shared data can be stored in the database, real-time updating of the shared data is achieved, the shared data can be obtained from the database, data sharing among different users is achieved, the requirement of a vehicle-mounted device on data safety can be met, a user can know vehicle information more, and user experience is improved.
Although the foregoing embodiments describe the steps in the above sequential order, those skilled in the art will understand that, in order to achieve the effect of the present embodiments, the steps may not be executed in such an order, and may be executed simultaneously (in parallel) or in an inverse order, and these simple variations are within the scope of the present invention.
