[0031] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0032] It should be pointed out that the embodiments of the present invention and the technical features therein may be combined with each other without conflict.

[0033] In addition, the terms "first", "second", "third", etc. included in the embodiments of the present invention are used to distinguish similar objects, and are not necessarily used to describe a specific number or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances. This is just a way of distinguishing objects with the same attributes when describing them in the embodiments of the present invention.

[0034] Furthermore, the vehicle involved in the embodiment of the present invention may be an internal combustion engine vehicle using an engine as a power source, a hybrid vehicle using an engine and an electric motor as a power source, an electric vehicle using an electric motor as a power source, or the like.

[0035] Figure 1 The following is a schematic diagram showing the main steps of the software update method provided by the embodiment of the present invention:

[0036] Step S101: In response to a software update, a first software update request is broadcast to other vehicle systems of a plurality of other vehicles via a short-range communication connection; the software update request includes software identification information.

[0037] Specifically, an embodiment of the present invention provides a method for downloading software between vehicles (vehicle-machine systems). Vehicles can communicate with each other via short-distance communication, where the short-distance communication technology can be wireless USB, IEEE802.11, Bluetooth, infrared, Zigbee, and the embodiment of the present invention does not limit the specific short-distance communication technology used in the vehicle.

[0038] Through short-distance communication connections, vehicles can directly transmit data and download software, overcoming the problems of network resource waste and download anomalies caused by network interruptions when all vehicles need to connect to the server through network communication and download software from the server when software upgrades are required.

[0039] It is understandable that the embodiments of the present invention may also be applied to software upgrades between other smart devices other than vehicles (such as smart refrigerators, smart terminals, etc.).

[0040] Furthermore, when there is a need for software upgrade in the vehicle system of any vehicle, the vehicle uses the vehicle system to broadcast a first software update request to other vehicle systems of multiple other vehicles; wherein the software update request includes software identification information. Among them, the software identification information includes software version information, vehicle configuration information, etc.; it can be understood that each software package includes software version information, and carrying software identification information in the software update request can clarify the software package corresponding to the version required by the vehicle, as well as the software package compatible with the vehicle. It can be understood that the software versions run by the vehicle systems of different vehicles are different, so by broadcasting the first software update request to other vehicle systems of multiple other vehicles, the vehicle systems (vehicles) with software packages matching the software version information and matching the vehicle configuration information can provide corresponding feedback. For example: vehicles of the same model can provide each other with upgrade software packages, or vehicles of the same manufacturer can provide each other with upgrade software packages, or vehicles of different manufacturers but with the same type of vehicle systems can provide each other with upgrade software packages.

[0041] Step S102: after receiving feedback information regarding the software update request sent by one or more of the other vehicle systems, determining one or more target vehicle systems according to the feedback information, and downloading an update software package from the target vehicle systems.

[0042] Specifically, after receiving feedback information regarding the software update request sent by one or more other vehicle systems, the vehicle system that needs to upgrade software determines one or more target vehicle systems based on the feedback information, wherein the one or more target vehicle systems can provide the update software package.

[0043] Furthermore, when it is determined based on the feedback information that there are multiple target vehicle systems that can provide update software packages, the distance between the vehicle where each target vehicle system is located and the vehicle status, etc. can be further determined; in one scenario, vehicle A parked in a parking lot is the demander of the update software package, and vehicle B parked in the parking lot and vehicle C driving nearby are both providers of the update software package; vehicle A can choose to download the update software package from the target vehicle system of vehicle B based on the distance between the vehicles and the vehicle status (stopped or driving), thereby improving the efficiency and reliability of downloading the software package; it can be understood that if vehicle A is a moving vehicle, vehicle A can choose to download the update software package from the target vehicle system of vehicle C based on the distance between the vehicles and the vehicle status (stopped or driving).

[0044] Furthermore, there are two methods for downloading the update software package from the target vehicle system:

[0045] The first method is to download the update software package directly from the target vehicle system. If the download of the update software package is interrupted due to communication interruption, the remaining part is continued to be downloaded from other target vehicle systems through the breakpoint resume technology until the complete update software package is obtained. That is, the download of the update software package from the target vehicle system includes: in the case where the download of the update software package from the target vehicle system is interrupted, the currently downloaded data information is recorded, and based on the currently downloaded information, the undownloaded data is downloaded by using the breakpoint resume technology.

[0046] The second method: preferably, a download request for the update software package is sent to one or more target vehicle systems, so that the target vehicle systems divide the update software package into multiple data blocks; and each data block is downloaded from one or more target vehicle systems. For example, if the update software package is 10G, the update software package can be divided into multiple data blocks, each data block is 100MB, so that each data block can be downloaded in a short time. The present invention does not limit the size of the update software package and the number of divided data blocks; by dividing the update software package into multiple data blocks, the vehicle system can download different data blocks from one or more vehicle systems respectively, which further improves the download efficiency, download flexibility and reliability.

[0047] Further, downloading data blocks from one or more target vehicle systems includes the following methods:

[0048] The first method is to directly download all the data blocks from one target vehicle system.

[0049] The second method is to download different data blocks from the plurality of target vehicle systems respectively.

[0050] The third method: when multiple target vehicle systems are determined, download the data block from the first target vehicle system; when the download is interrupted, continue to download the remaining data blocks from the second target vehicle system.

[0051] That is, downloading the data blocks from one or more target vehicle systems includes: downloading all the data blocks directly from one target vehicle system; or, downloading different data blocks from multiple target vehicle systems respectively; or, when multiple target vehicle systems are determined, downloading the data blocks from the first target vehicle system; and when the download is interrupted, downloading the remaining data blocks from the second target vehicle system.

[0052] The embodiment of the present invention adopts different methods for downloading data blocks according to different scenarios, which further improves the flexibility of downloading data blocks, thereby improving the flexibility and reliability of downloading update software packages.

[0053] Further preferably, the target vehicle system providing the update software package may further compress the data blocks to obtain compressed data blocks in addition to dividing the update software package into a plurality of data blocks, thereby further improving download efficiency.

[0054] Furthermore, in the case where the downloading of the data block or compressed data block from the target vehicle system is interrupted, the currently downloaded data information is recorded, and based on the currently downloaded information, the download of the undownloaded data is performed by utilizing breakpoint resumption.

[0055] The embodiments of the present invention improve the reliability of downloading update software packages by dividing the update software package into data blocks, downloading data blocks from different vehicles, and performing breakpoint resumption operations, so that vehicles can still download data and complete software updates through short-distance communication with other vehicles in locations where there is a lack of network communication signals (such as underground parking lots).

[0056] Step S103: Use the update software package to update the existing software.

[0057] Specifically, after determining that the download of the update software package is complete, the vehicle system executes an update operation for the vehicle system software, so that the existing software is upgraded to the latest software version (ie, the updated software).

[0058] Furthermore, in the case that the downloaded update software package is a plurality of data blocks, the downloaded data blocks are integrated into a download software package, and the download software package is used to update the existing software.

[0059] Furthermore, in the case that the downloaded data blocks are compressed data blocks, a decompression operation is performed on each of the downloaded compressed data blocks, the decompressed data blocks are integrated into a download software package, and the download software package is used to update the existing software.

[0060] Further, after integrating the downloaded data blocks into a download software package and before using the download software package to update the existing software, verification is performed on the download software package to determine that the download software package is complete and has not been changed.

[0061] By integrating and verifying data blocks or compressed data blocks, the security and reliability of executing updated software are improved.

[0062] Furthermore, in an embodiment of the present invention, the vehicle system that sends the software update request may also be a vehicle system that provides the latest software package for the vehicle systems of other vehicles; specifically, when the vehicle system is the software package provider, the steps of dividing the update software package into multiple data blocks, compressing the data blocks, etc. are performed so that other vehicle systems can download the compressed data blocks from the vehicle system. That is, the second software update request broadcasted by other vehicle systems is received; in the case of having an update software package corresponding to the second software update request, feedback information for the second software update request is sent to the other vehicle systems; after receiving the download instruction of the other vehicle systems, the update software package is divided into multiple data blocks, and compression is performed on each data block to generate a compressed data block, so that the other vehicle systems can download the compressed data block.

[0063] Figure 2 A schematic diagram showing the main steps of another software updating method that can be applied to an embodiment of the present invention is shown:

[0064] Step S201: In response to the software update, the vehicle system broadcasts a first software update request to other vehicle systems of multiple other vehicles via a short-range communication connection.

[0065] Step S202: after receiving feedback information regarding the software update request sent by one or more of the other vehicle-mounted systems, determining one or more target vehicle-mounted systems according to the feedback information.

[0066] Step S203: sending a download request for the update software package to one or more of the target vehicle systems, so that the target vehicle systems divide the update software package into a plurality of data blocks (or compressed data blocks).

[0067] Step S204: downloading each of the data blocks (or compressed data blocks) from one or more of the target vehicle systems.

[0068] Step S205: Integrate the downloaded data blocks (or compressed data blocks) into a download software package, and use the download software package to update the existing software.

[0069] Specifically, the process described in steps S201 to S205 in which any one of the vehicle systems downloads data blocks from other vehicle systems and integrates the data blocks to complete the software update is consistent with the description of steps S101 to S103 and will not be repeated here.

[0070] like Figure 3 As shown, a software updating device provided by an embodiment of the present invention is applied to a vehicle system, comprising:

[0071] A signal management module 301, which is used to broadcast a first software update request to other vehicle systems of multiple other vehicles in response to the software update through a short-distance communication connection; the software update request includes software version information;

[0072] A download module 302, which is used to determine one or more target vehicle systems according to the feedback information after receiving feedback information sent by one or more other vehicle systems for the software update request, and download the update software package from the target vehicle systems;

[0073] The updating module 303 is used to update the existing software using the updating software package.

[0074] Furthermore, the embodiment of the present invention may also include an integration module for integrating the downloaded data blocks into a download software package; or, performing a decompression operation on the downloaded compressed data blocks and integrating the decompressed data blocks into a download software package; and a rule management module for managing the software identification information contained in different software packages.

[0075] Figure 4 1 is a system architecture diagram of a software update provided by an embodiment of the present invention. Figure 4 As shown, it includes vehicle computer systems V1, V2...Vn of multiple vehicles; wherein V1 is the party in need of the update software package, and in response to the software update, V1 broadcasts a first software update request to other vehicle computer systems of multiple other vehicles through a short-distance communication connection; after receiving feedback information regarding the software update request sent by one or more other vehicle computer systems, one or more target vehicle computer systems (V2...Vn) are determined according to the feedback information, and the update software package is downloaded from the target vehicle computer systems (V2...Vn); and the existing software is updated using the update software package.

[0076] At the same time, V1 can also act as an update software provider and receive second software update requests broadcast by other vehicle systems (V2...Vn); when it has an update software package corresponding to the second software update request, it sends feedback information for the second software update request to other vehicle systems (V2...Vn); after receiving the download instructions from other vehicle systems, it divides the update software package into multiple data blocks, and performs compression on each data block to generate compressed data blocks, so that other vehicle systems (V2...Vn) can download the compressed data blocks.

[0077] It should be understood that Figure 4 The number of vehicles in is only illustrative. Depending on the implementation needs, there can be any number of vehicles.
