The same reference numerals in the accompanying drawings indicate the same or similar components or parts. It should be understood by those skilled in the art that these drawings are not necessarily drawn to scale. In the accompanying drawings:

[0026] The specific implementation of the embodiment of the present invention is further described below in conjunction with the accompanying drawings of the embodiment of the present invention.

[0027] Embodiment 1

[0028] The present application embodiment provides a method for updating a vehicle application, such as Figure 1 As shown, Figure 1 A flowchart of a vehicle application update method provided in an embodiment of the present application. The vehicle application update method comprises the following steps:

[0029] Step 101: Run the operating system program stored in the primary partition in the vehicle storage space.

[0030] The vehicle application update method provided in the embodiment of the present application is applied to an on-board electronic device, and the vehicle storage space may be a storage medium in the on-board electronic device. The vehicle storage space includes multiple areas, such as a main partition, an extended application partition, a boot partition, and a shared data area.

[0031] Among them, the main partition stores the operating system program, and the main partition can also store the core application program. The main partition can be further divided into a first partition and a second partition. The first partition stores the operating system program, and the second partition stores the core application program. If the core application program is updated, it may not affect the operating system program. Of course, this is just an exemplary description and does not mean that the present application is limited to this; the boot partition stores the boot loader. The boot loader is a program that runs before the operating system runs when the vehicle-mounted electronic device is started. It can initialize the hardware device, establish a memory space mapping map, and configure the software environment and hardware environment of the operating system of the vehicle-mounted electronic device; the extended application area includes at least one application partition, and each application partition stores the corresponding vehicle application program and data; the shared data area stores data shared between at least one vehicle application and the application partition address corresponding to each vehicle application in the extended application area.

[0032] Of course, this is just an exemplary explanation. The vehicle storage space may include at least one of a main partition, an extended application partition, a boot partition, and a shared data area. In an embodiment of the present application, the vehicle storage space may include a main partition and an extended application partition.

[0033] When the vehicle storage space includes a boot partition, optionally, in one embodiment of the present application, the method further includes: executing a boot loader stored on the boot partition in the vehicle storage space, detecting a partition flag of each application partition, the partition flag being used to indicate whether the application partition has been updated; and updating the application partition to be updated according to the partition flag of each application.

[0034] The partition flag may include two states, a pending update state and a no update state, which may be represented by a binary digit. For example, a partition flag value of "1" indicates that the corresponding application partition needs to be updated (i.e., a pending update state), and a partition flag value of "0" indicates that the corresponding application partition does not need to be updated (i.e., no update state). Of course, this is just an example. Spatially upgrading and updating each application partition can make each application partition large enough to meet the hardware resource requirements for the corresponding vehicle application update. It should be noted that after updating the application partition, the application partition address of the shared data area also needs to be updated.

[0035] For example, in one application scenario, when the target vehicle application needs to be updated, the partition flag of the target application partition corresponding to the target vehicle application is set to a pending update state. When the on-board electronic device is started next time, the boot loader is run first. At this time, it is determined that the partition flag of the target application partition is in a pending update state, and the target application partition is expanded to reserve sufficient space for updating the target vehicle application.

[0036] Step 102 : Determine a target application partition corresponding to a target vehicle application to be updated in an extended application area in the vehicle storage space according to an application address list in a shared data area in the vehicle storage space.

[0037] It should be noted that, in the present application, the target is only used to indicate the singular and is not limited in any way. For example, the target vehicle application indicates a vehicle application and can be any vehicle application.

[0038] The application address list is used to indicate the application partition address of at least one vehicle application, and the target vehicle application belongs to at least one vehicle application. In the extended application area, each vehicle application corresponds to an application partition, and each application partition has a corresponding application partition address. The application address list is used to indicate the correspondence between at least one vehicle application and at least one application partition address.

[0039] It should be noted that the target vehicle application to be updated can be a vehicle application that has been installed on the on-board electronic device, or it can be an uninstalled vehicle application. If the target vehicle application has been installed, the application partition address of the target vehicle application can be directly found according to the application address list. If the target vehicle application is not installed, it is necessary to first set the corresponding target application partition for the target vehicle application and update the application address list.

[0040] For example, in one embodiment of the present application, when the target vehicle application is a newly added application, the method further includes: setting a corresponding target application partition for the target vehicle application in the extended application area.

[0041] Step 103 : updating the target vehicle application in the target application partition according to the update data of the target vehicle application.

[0042] After determining the target application partition, updating the target vehicle application only requires updating the data in the target application partition, without affecting the operating system program and other vehicle application programs.

[0043] Here, a specific example is given to illustrate how to update the target vehicle application. Optionally, in one embodiment of the present application, updating the target vehicle application in the target application partition according to the update data of the target vehicle application includes:

[0044] A new process is set for the update task of the target vehicle application; and the target vehicle application is updated in the target application partition according to the update data of the target vehicle application using the new process.

[0045] It should be noted that after running the operating system program, a process needs to be assigned to each task to be executed. A process is an operation activity related to a data set and is the basic unit for resource allocation and scheduling of the operating system. When there are multiple application tasks waiting to be executed, each task is called periodically. A fixed time interval (such as 5ms, 1ms or 10ms) can be set to run the corresponding vehicle application according to the process queue and the application address list of the shared data area. The execution cycle of each task is an integer multiple of the fixed time interval.

[0046] Optionally, in one embodiment of the present application, the method further includes: updating the application address list according to the updated target vehicle application. For example, if the target application partition is expanded before the target vehicle application is updated, the storage space size of the target application partition can be restored after the target vehicle application is updated. The specific process is similar to the process of expanding the target application partition in the explanation of step 101, and will not be repeated here.

[0047] In an optional application scenario, the vehicle application on the vehicle-mounted electronic device can also be uninstalled. For example, taking the uninstallation of the target vehicle application as an example, the target application partition corresponding to the target vehicle application in the extended application area is determined according to the application address list. During the operation of the operating system program, a new process is assigned to the uninstallation task of the target vehicle application, and the target vehicle application is uninstalled in the target application partition using the process. Specifically, the programs and data stored in the target application partition can be deleted, and the target application partition can be determined as the storage space to be allocated, and the address of the target application partition can be deleted from the application address list. Not only is flexible updating of each vehicle application achieved, but also installation (i.e., adding) of vehicle applications and uninstallation of vehicle applications are achieved, and flexible management of vehicle applications is achieved. Of course, this is only an exemplary description and does not mean that the present application is limited to this.

[0048] In an embodiment of the present application, the vehicle storage space includes a main partition and an extended application partition. The main partition stores an operating system program. In the extended application partition, each vehicle application has a corresponding application partition. Each vehicle application can be updated flexibly without affecting the operation of the operating system program in the main partition. Vehicle application updates and additions and deletions are more convenient.

[0068] The vehicle-mounted electronic device of the embodiment of the present application exists in various forms, including but not limited to:

[0069] (1) Mobile communication devices: These devices are characterized by having mobile communication functions and their main purpose is to provide voice and data communications. These terminals include: smart phones (such as iPhone), multimedia phones, functional phones, and low-end phones.

[0073] Thus far, specific embodiments of the subject matter have been described. Other embodiments are within the scope of the appended claims. In some cases, the actions recited in the claims may be performed in a different order and still achieve the desired results. Additionally, the processes depicted in the accompanying drawings do not necessarily require the specific order or sequential order shown to achieve the desired results. In some embodiments, multitasking and parallel processing may be advantageous.

[0074] In the 1990s, improvements to a technology could be clearly distinguished as hardware improvements (for example, improvements to the circuit structure of diodes, transistors, switches, etc.) or software improvements (improvements to the method flow). However, with the development of technology, many improvements to the method flow today can be regarded as direct improvements to the hardware circuit structure. Designers almost always obtain the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that an improvement in a method flow cannot be implemented using a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the user's programming of the device. Designers can "integrate" a digital system on a PLD by programming it themselves, without having to ask a chip manufacturer to design and produce a dedicated integrated circuit chip. Moreover, nowadays, instead of manually making integrated circuit chips, this kind of programming is mostly implemented by "logic compiler" software, which is similar to the software compiler used when developing and writing programs, and the original code before compilation must also be written in a specific programming language, which is called hardware description language (HDL). There is not only one HDL, but many kinds, 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 should also know that it is only necessary to program the method flow slightly in the above-mentioned hardware description languages ​​and program it into the integrated circuit, and then it is easy to obtain the hardware circuit that implements the logic method flow.

[0075] The systems and devices described in the above embodiments can be implemented by computer chips or entities, or by products with certain functions. A typical implementation device is a computer. Specifically, the computer can be, for example, a personal computer, a laptop computer, a cellular phone, a camera phone, a smart phone, 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.

Moreover, the present application may adopt the form of a computer program product implemented in one or more computer-usable storage media (including but not limited to disk storage, CD-ROM, optical storage, etc.) that include computer-usable program code.

[0080] In a typical configuration, a computing device includes one or more processors (CPU), input / output interfaces, network interfaces, and memory.

[0081] The memory may include non-permanent storage in a computer-readable medium, random access memory (RAM) and / or non-volatile memory in the form of read-only memory (ROM) or flash RAM. The memory is an example of a computer-readable medium.
