OTA (Over The Air) technology provides an online upgrade technology that enables the upgrade of each vehicle controller to be as convenient and efficient as the upgrade of mobile phone applications.

[0003] However, with the increase in vehicle controller software versions (i.e. OTA update packages), the efficiency of OTA upgrades has gradually decreased.

[0004] Therefore, this application is specially filed. Summary of the invention

[0005] In view of this, the purpose of this application is to propose a vehicle update package processing method, electronic device and vehicle, which is conducive to improving the vehicle OTA update efficiency, reducing user waiting time, optimizing the utilization of server resources, reducing storage costs, and being more adaptable to fast-paced update iterations, thereby improving the update quality of vehicle software and user satisfaction.

[0008] Based on the attribute data, determining a target software package among multiple version software packages;

[0009] Generate and store a corresponding differential update package for the target software package.

[0010] Here, the "multiple" in "multiple version software packages" does not refer to a part of all version software packages, but refers to the number of all version software packages being multiple.

[0011] Further, the attribute data includes a usage frequency and a version date, and determining a target software package from multiple versions of software packages based on the attribute data includes:

[0012] Determine the first candidate software package according to the usage frequency of each version of the software package;

[0015] Furthermore, the determining of the first candidate software package according to the usage frequency of each version of the software package includes:

[0016] Sort the software packages of each version in descending order according to their usage frequency;

[0017] A first preset number of version software packages ranked top are determined as the first candidate software packages; or a version software package whose usage frequency reaches a frequency threshold is determined as the first candidate software package.

[0018] Further, determining the second candidate software package according to the version date of each version software package includes:

[0019] Sort the software packages in order of their version dates from the most recent to the most recent.

[0020] A second preset number of version software packages ranked top are determined as the second candidate software packages; or a version software package with a version date between the current time point and a historical time point is determined as the second candidate software package.

[0021] Further, determining the target software package according to the first candidate software package and / or the second candidate software package includes:

[0022] Determining the first candidate software package as the target software package;

[0023] Alternatively, determining the second candidate software package as the target software package;

[0024] Alternatively, a union of the first candidate software package and the second candidate software package is determined as the target software package;

[0025] Alternatively, the intersection of the first candidate software package and the second candidate software package is determined as the target software package.

[0026] Furthermore, it also includes:

[0027] In response to storing a differential update package corresponding to a non-target software package other than the target software package, the differential update package corresponding to the non-target software package is deleted.

[0028] Further, generating and storing a corresponding differential update package for the target software package includes:

[0029] Determine the difference data between every two target software packages and the location of the difference data, or determine the difference data between every two target software packages with adjacent versions and the location of the difference data;

[0030] The difference data and the location of the difference data are recorded to obtain a difference update package between the two target software packages.

[0031] Furthermore, it also includes:

[0032] In response to receiving an update instruction from the vehicle, determining a first identity identifier of an old software package to be updated and a second identity identifier of a new software package to be updated;

[0033] determining whether a differential update package between the old software package and the new software package is stored according to the first identity identifier and the second identity identifier;

[0034] In response to storing a differential update package between the old software package and the new software package, sending the differential update package to the vehicle;

[0035] In response to the fact that a differential update package between the old software package and the new software package is not stored, a differential update package between the old software package and the new software package is calculated online, and the differential update package is sent to the vehicle.

[0036] Based on the above purpose, in a second aspect, the present application also provides a method and device for processing a vehicle update package, including:

[0037] The acquisition module is used to obtain the attribute data of each version of the software package;

[0038] A determination module, configured to determine a target software package among multiple version software packages based on the attribute data;

[0043] From the above, it can be seen that the vehicle update package processing method provided by the present application is not to pre-generate and store corresponding differential update packages for all versions of the software package, but to select some from all versions of the software package as the target software package, and only pre-generate and store corresponding differential update packages for the target software package. This can reduce the storage quantity of differential update packages, thereby reducing the storage cost of the server and optimizing the resource utilization of the server. By pre-generating and storing differential update packages, when the vehicle side needs to be updated and upgraded, the differential update package can be directly sent to the vehicle side, which can save the time consumed in generating differential update packages, reduce the user's waiting time, and improve the update efficiency.

[0055] In order to make the objectives, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0056] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should be the usual meanings understood by people with ordinary skills in the field to which the present application belongs. The "first", "second" and similar words used in the embodiments of the present application do not represent any order, quantity or importance, but are only used to distinguish different components. "Including" or "comprising" and similar words mean that the elements or objects appearing in front of the word cover the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0057] At present, the update iteration of vehicle controller ECU software is getting faster and faster. OTA (Over The Air) technology provides an online upgrade technology, which makes the upgrade of each vehicle controller as convenient and efficient as the upgrade of mobile phone applications. However, with the increase of vehicle controller software versions (i.e. OTA update packages), the efficiency of OTA upgrades has gradually decreased.

[0058] Specifically, vehicle OTA update methods include full update and differential update. Among them, full update is to send the entire software package of the new version to the vehicle for installation and update. Its advantage is that the update process is relatively simple and direct, and compatibility issues are not likely to occur. But the disadvantages are also obvious. The full update package is usually large, takes a long time to download, consumes more network traffic, and has high requirements for vehicle storage space.

[0059] Differential update only sends the difference between the new and old versions (i.e., differential update package). The advantage of this method is that the update package is small, so the download speed is fast, saving network traffic and vehicle storage space. However, the generation and application of differential updates are relatively complex, requiring accurate version comparison and processing. As the number of versions increases, the number of differential update packages increases exponentially. For example, for a certain controller software of a vehicle, there are a total of n versions, and the number of differential update packages that may appear is n(n-1) / 2. If all differential update packages are generated in advance and stored on the server, it will take up a large storage space. If the differential update package is not generated and stored in advance, then the differential update package needs to be calculated online each time the terminal requests it, which will obviously waste more time and occupy more computing power, resulting in reduced update efficiency.

[0060] Therefore, if a single update method is used without fully considering the software usage rate, version differences and actual user needs, it will lead to either inefficient update efficiency or waste of storage space or computing power during the update process.

[0061] In response to the above problems, an embodiment of the present application provides a method for processing a vehicle update package. The method for processing a vehicle update package provided by the embodiment of the present application can improve the efficiency of vehicle OTA updates, reduce user waiting time, optimize server resource utilization, reduce storage costs, and be more adaptable to fast-paced update iterations, thereby improving the update quality of vehicle software and user satisfaction.

[0062] Figure 1 A flow chart of a method for processing a vehicle update package is shown. The method for processing a vehicle update package can be executed by a processing device for the vehicle update package. The processing device for the vehicle update package can be implemented in the form of software and / or hardware and integrated in a server.

[0063] like Figure 1 As shown, the method for processing the vehicle update package includes the following steps:

[0064] S110: Obtain attribute data of each version of the software package.

[0065] Herein, each version software package refers to a data package for different versions of the same vehicle controller software. For example, if a certain vehicle controller software includes 20 versions in total, then each version software package refers to any version of the 20 versions.

[0066] The attribute data of the software package includes data characterizing the popularity of the software package, or data characterizing the needs of vehicle users. For example, the attribute data of the software package may refer to the number of times and frequency of the software package being installed and used by the vehicle, or may refer to the rating of the software package, the version date of the software package, etc. Among them, the higher the rating of the software package, the more popular the software package is among users, or in other words, the more vehicle users have a need to install the software package. The closer the version date of the software package is to the current time, the newer the software package is. Generally, vehicle users have a higher need to install the new version, so the new version is more popular. The more times the software package is installed and used by the vehicle, the more popular the software package is among users; similarly, the more frequently the software package is installed and used by the vehicle, the more popular the software package is among users.

[0067] S120: Determine a target software package from multiple versions of software packages based on the attribute data.

[0068] Specifically, multiple versions of software packages are screened with reference to the attribute data to obtain a target software package.

[0069] In some implementations, based on the attribute data, target software packages that are installed and used more frequently by vehicles are screened out from multiple versions of software packages, or in other words, target software packages that are more popular with users are screened out, thereby achieving the purpose of making the number of target software packages less than the number of all software packages.

[0070] S130: Generate and store a corresponding differential update package for the target software package.

[0071] The differential update package refers to a data package that records the difference between two software packages. Specifically, the differential update package described in this embodiment refers to a data package that records the difference between each two target software packages. For example, if the target software packages are software package A, software package B, and software package C, then the meaning of generating and storing the corresponding differential update packages for the target software packages is: calculating and storing the differential update package between software package A and software package B, calculating and storing the differential update package between software package A and software package C, and calculating and storing the differential update package between software package B and software package C.

[0072] Compared to generating and storing corresponding differential update packages for all versions of software packages, only generating and storing corresponding differential update packages for target software packages reduces the number of stored differential update packages, thereby reducing storage costs and reducing the requirements for server storage capabilities. At the same time, by pre-generating and storing corresponding differential update packages for target software packages, when the vehicle side needs to be updated, there is no need to calculate the differential update package online, but directly read the stored differential update package and send it to the vehicle, which can save more time and reduce the waiting time of vehicle users, thereby improving update efficiency and user experience. In addition, by using differential update packages for updates, the amount of data downloaded by the vehicle side is less, which further saves time and improves overall efficiency.

[0073] The vehicle update package processing method provided in the embodiment of the present application does not pre-generate and store corresponding differential update packages for all versions of the software packages, but selects some from all versions of the software packages as target software packages, and pre-generates and stores corresponding differential update packages only for the target software packages. This can reduce the storage quantity of differential update packages, thereby reducing the storage cost of the server and optimizing the resource utilization of the server. By pre-generating and storing differential update packages, when the vehicle side needs to be updated and upgraded, the differential update package can be directly sent to the vehicle side, which can save the time consumed in generating differential update packages, reduce the waiting time of users, and improve the update efficiency.

[0074] Based on the above embodiment, this embodiment provides an optional implementation method for the step S120 "determining a target software package from multiple versions of software packages based on the attribute data", such as Figure 2 A flow chart of a method for processing a vehicle update package is shown, wherein the method for processing a vehicle update package comprises the following steps:

[0075] S210: Obtain attribute data of each version of the software package.

[0076] Exemplarily, the attribute data includes the usage frequency and version date of the software package. Among them, the closer the version date is to the current time, the newer the version of the corresponding software package is, and the new version of the software package is usually required by the user. The usage frequency of a certain software package may specifically refer to the ratio of the number of times the software package has been installed and used by the vehicle in the past six months to the total number of times all software packages have been installed and used by the vehicle. Alternatively, the number of times a certain software package has been installed and used by a vehicle in the past six months can also be used to represent its usage frequency. If a software package is installed and used by a vehicle more times, or the frequency of use is higher, it means that the software package is more popular with the vehicle. For software packages that are more popular with vehicles, the corresponding differential update packages are pre-generated and stored, so that when a vehicle needs to install and use the software package, the corresponding differential update package can be directly sent to the vehicle for installation and use by the vehicle, which can save the time consumed by online calculation of differential update packages, improve the overall update efficiency, reduce user waiting time, and improve the user experience.

[0077] S220: Determine a first candidate software package according to the usage frequency of each version of the software package.

[0078] Specifically, a software package with a higher frequency of use may be determined as the first candidate software package to screen out a software package that is more popular with the vehicle.

[0079] S230: Determine a second candidate software package according to the version date of each version software package.

[0080] Optionally, a software package with a newer version date may be determined as a second candidate software package to screen out a software package that is more likely to be required by the vehicle.

[0081] S240: Determine the target software package according to the first candidate software package and / or the second candidate software package.

[0082] In some implementations, the first candidate software package is determined as the target software package.

[0083] In some implementations, the second candidate software package is determined as the target software package.

[0084] In some implementations, both the first candidate software package and the second candidate software package are determined as the target software package. For example, assuming that the first candidate software package includes software package A and software package B, and the second candidate software package includes software package B and software package C, software package A, software package B, and software package C are determined as the target software packages.

[0085] In some implementations, the intersection of the first candidate software package and the second candidate software package is determined as the target software package to further improve the accuracy of determining the target software package, so that the target software package determined in this way is more likely to be the software package required by the vehicle. For example, assuming that the first candidate software package includes software package A and software package B, and the second candidate software package includes software package B and software package C, software package B is determined as the target software package.

[0086] S250: Generate and store a corresponding differential update package for the target software package.

[0087] The vehicle update package processing method provided in the embodiment of the present application screens the target software package from multiple software packages based on the usage frequency and / or version date of the software package, thereby achieving the purpose of obtaining a software package that is more popular with the vehicle, and then pre-generates and stores corresponding differential update packages for such software packages. When the vehicle needs to install a certain software package, the corresponding differential update package can be directly sent to the vehicle, thereby saving the time for online real-time calculation of the differential update package, reducing the user's waiting time, improving the overall update efficiency, and helping to improve the user's vehicle experience.

[0088] Based on the above embodiment, this embodiment provides an optional implementation method for step S220 "determining the first candidate software package according to the usage frequency of each version of the software package", such as Figure 3 A flow chart of a method for processing a vehicle update package is shown, wherein the method for processing a vehicle update package comprises the following steps:

[0089] S310: Obtain attribute data of each version of the software package.

[0090] S320: Sort the version software packages in descending order of usage frequency; determine a first preset number of version software packages that are ranked top as the first candidate software packages; or determine a version software package whose usage frequency reaches a frequency threshold as the first candidate software package.

[0091] The first preset number is determined based on the remaining storage space of the server.

[0092] In some implementations, the number of differential update packages that can be stored is estimated based on the remaining storage space of the server, and then the first preset number is determined based on the number of differential update packages that can be stored, and finally the sorted topN software packages are determined as the first candidate software packages, where N is the first preset number.

[0093] In some implementations, if there are a large number of version software packages whose usage frequencies reach a frequency threshold, a first preset number of version software packages may be selected as first candidate software packages to take into account the storage capacity of the server.

[0094] S330: Determine a second candidate software package according to the version date of each version software package.

[0095] S340: Determine the target software package according to the first candidate software package and / or the second candidate software package.

[0096] S350: Generate and store a corresponding differential update package for the target software package.

[0097] The vehicle update package processing method provided in the embodiment of the present application estimates the number of differential update packages that can be stored according to the remaining storage space of the server, and then determines the first preset number N according to the number of differential update packages that can be stored, and finally determines the top N sorted software packages as the first candidate software packages, thereby achieving the purpose of taking into account the storage capacity of the server and reducing the requirements for the storage capacity of the server.

[0098] Based on the above embodiment, this embodiment provides an optional implementation method for step S230 "determining the second candidate software package according to the version date of each version software package", such as Figure 4 A flow chart of a method for processing a vehicle update package is shown, wherein the method for processing a vehicle update package comprises the following steps:

[0099] S410: Obtain attribute data of each version of the software package.

[0100] S420: Determine a first candidate software package according to the usage frequency of each version of the software package.

[0101] S430: Sort the version software packages according to the order of their version dates from recent to recent; determine a second preset number of version software packages that are ranked top as the second candidate software packages; or determine the version software packages whose version dates are between the current time point and the historical time point as the second candidate software packages.

[0102] The second preset number is determined according to the remaining storage space of the server. Specifically, the number of differential update packages that can be stored is estimated according to the remaining storage space of the server, and then the second preset number is determined according to the number of differential update packages that can be stored, and finally the top N ranked software packages are determined as the second candidate software packages, where N is the second preset number.

[0103] The closer the version date is to the current time, the newer the corresponding software package is, and the newer the software package is, the more likely it is that the vehicle needs to install and use it. Therefore, by screening multiple software packages according to the version date of the software package, the newer software package is used as the second candidate software package, making the second candidate software package more likely to be the software package that the vehicle needs to install and use, and pre-generating and storing differential update packages for such software packages. When the vehicle needs to install and use it, the pre-stored differential update package can be directly sent to the vehicle without the need to calculate the differential update package online in real time, thereby saving time, reducing the waiting time of users, and improving the overall efficiency of the update.

[0104] In some implementations, software packages with version dates within the past six months may also be determined as the second candidate software packages. If there are a large number of software packages with version dates within the past six months, some of them may be used as second candidate software packages. Specifically, they may be screened according to version date so that the second candidate software packages are software packages with newer version dates.

[0105] S440: Determine the target software package according to the first candidate software package and / or the second candidate software package.

[0106] S450: Generate and store a corresponding differential update package for the target software package.

[0107] The vehicle update package processing method provided in the embodiment of the present application sorts the version software packages in order of version date from recent to ancient, and determines a second preset number of version software packages that are ranked first as the second candidate software packages; or determines a version software package whose version date is between the current time point and the historical time point as the second candidate software package, thereby achieving the purpose of screening multiple version software packages based on the version date, so that the screening result is a software package with a newer version date, so as to obtain a software package that is more likely to be required to be installed and used by the vehicle.

[0108] Based on the above embodiment, this embodiment provides an optional implementation method for step S240 "determining the target software package according to the first candidate software package and / or the second candidate software package", such as Figure 5 A flow chart of a method for processing a vehicle update package is shown, wherein the method for processing a vehicle update package comprises the following steps:

[0109] S510: Obtain attribute data of each version of the software package.

[0110] S520: Determine a first candidate software package according to the usage frequency of each version of the software package.

[0111] S530: Determine a second candidate software package according to the version date of each version software package.

[0112] S540: Determine the first candidate software package as the target software package; or determine the second candidate software package as the target software package; or determine the union of the first candidate software package and the second candidate software package as the target software package; or determine the intersection of the first candidate software package and the second candidate software package as the target software package.

[0113] In some implementations, the first candidate software package is determined as the target software package.

[0114] In some implementations, the second candidate software package is determined as the target software package.

[0115] In some implementations, both the first candidate software package and the second candidate software package are determined as the target software package. For example, assuming that the first candidate software package includes software package A and software package B, and the second candidate software package includes software package B and software package C, software package A, software package B, and software package C are determined as the target software packages.

[0116] In some implementations, the intersection of the first candidate software package and the second candidate software package is determined as the target software package to further improve the accuracy of determining the target software package, so that the target software package determined in this way is more likely to be the software package required by the vehicle. For example, assuming that the first candidate software package includes software package A and software package B, and the second candidate software package includes software package B and software package C, software package B is determined as the target software package.

[0117] S550: Generate and store a corresponding differential update package for the target software package.

[0118] The vehicle update package processing method provided in the embodiment of the present application, by determining the first candidate software package as the target software package; or determining the second candidate software package as the target software package; or determining the union of the first candidate software package and the second candidate software package as the target software package; or determining the intersection of the first candidate software package and the second candidate software package as the target software package, achieves the purpose of fully determining the target software package according to the use frequency and version date of the software package, so that the target software package is a software package with a high use frequency and a newer version date, and finds the software package that meets the vehicle installation and use requirements to the greatest extent, and achieves the balance between the vehicle software update efficiency and the server storage capacity. That is, the differential update packages of all software packages are not stored, thereby reducing the requirements for the server storage capacity, and the differential update packages of the software packages that need to be installed and used by the vehicle can be stored, thereby improving the vehicle software update efficiency.

[0119] Based on the above embodiment, this embodiment adds the following step: "In response to storing a differential update package corresponding to a non-target software package other than the target software package, deleting the differential update package corresponding to the non-target software package", such as Figure 6 A flow chart of a method for processing a vehicle update package is shown, wherein the method for processing a vehicle update package comprises the following steps:

[0120] S610: Obtain attribute data of each version of the software package.

[0121] S620: Determine a first candidate software package according to the usage frequency of each version of the software package.

[0122] S630: Determine a second candidate software package according to the version date of each version software package.

[0123] S640: Determine the target software package according to the first candidate software package and / or the second candidate software package.

[0124] S650: Generate and store a corresponding differential update package for the target software package.

[0125] S660: In response to storing a differential update package corresponding to a non-target software package other than the target software package, delete the differential update package corresponding to the non-target software package.

[0126] As time goes by, the usage frequency of some software packages will change, and their version dates will become older and older, so the target software package will change. When it is detected that a differential update package corresponding to a non-target software package other than the target software package is stored, the differential update package corresponding to the non-target software package is deleted to release storage space, thereby achieving reasonable utilization of storage resources and allowing limited storage space to be used to store differential update packages corresponding to software packages that are more likely to be installed and used by the vehicle.

[0127] The vehicle update package processing method provided in the embodiment of the present application adds an operation of dynamically processing differential update packages. In response to storing a differential update package corresponding to a non-target software package other than the target software package, the differential update package corresponding to the non-target software package is deleted to release storage space, thereby achieving rational use of storage resources and allowing limited storage space to be used to store differential update packages corresponding to software packages that are more likely to be installed and used by the vehicle.

[0128] Based on the above embodiment, this embodiment provides an optional implementation method for the above step S130 "generating and storing a corresponding differential update package for the target software package". Figure 7 A flow chart of a method for processing a vehicle update package is shown, wherein the method for processing a vehicle update package comprises the following steps:

[0129] S710: Obtain attribute data of each version of the software package.

[0130] S720: Determine a first candidate software package according to the usage frequency of each version of the software package.

[0131] S730: Determine a second candidate software package according to the version date of each version software package.

[0132] S740: Determine the target software package according to the first candidate software package and / or the second candidate software package.

[0133] S750, determining the difference data between every two target software packages and the location of the difference data, or determining the difference data between every two target software packages with adjacent versions and the location of the difference data; recording the difference data and the location of the difference data, and obtaining a differential update package between the corresponding two target software packages.

[0134] In some implementations, for example, if the target software packages are arranged in order from the earliest to the latest version date, they are A, B, C, and D, respectively, then the difference data between A and B and the location of the difference data are calculated, the difference data and the location of the difference data are recorded, and the difference update package between A and B is obtained. Similarly, the difference update package between A and C, the difference update package between A and D, the difference update package between B and C, the difference update package between B and D, and the difference update package between C and D are calculated. That is, the difference update package between every two target software packages is determined.

[0135] In some implementations, for example, if the target software packages are arranged in order from the earliest to the latest version date, respectively, A, B, C, and D, then the differential update package between A and B, the differential update package between B and C, and the differential update package between C and D are calculated respectively. That is, the differential update package between two software packages of adjacent versions is determined.

[0136] In some embodiments, for example, the versions of a software package range from ver1.0, ver1.1, ver1.2…ver2.9, a total of 20 versions. There may be 190 combinations of differential versions. If all these 190 combinations are pre-generated as differential update packages and stored on the server, a lot of storage space will be wasted. Therefore, a strategy can be formulated, such as storing only 20 differential update packages with the highest probability of being installed and used by vehicles, such as 10 differential update packages corresponding to 10 combinations between the 5 most recent versions, and 10 differential update packages corresponding to 10 combinations between the 5 most frequently used versions in the past six months. When the differential update package that the vehicle needs to install and use belongs to one of these 20 packages, it will be distributed directly from the server to the vehicle. If not, two complete software packages will be taken to generate differential update packages in real time and distribute them.

[0137] The vehicle update package processing method provided in the embodiment of the present application is for calculating the corresponding differential update package for each two target software packages, or for calculating the corresponding differential update package for two adjacent versions in the target software packages. Specifically, the difference data between the two target software packages and the location of the difference data are determined, the difference data and the location of the difference data are recorded, and the differential update package between the two target software packages is obtained.

[0138] Based on the above embodiment, this embodiment adds a differential update package distribution step. Specifically, when a vehicle needs to upgrade a certain software package, the server searches for a differential update package between the software package currently in use on the vehicle (i.e., the software package to be upgraded) and the software package the vehicle expects to upgrade to, and if a corresponding differential update package is pre-stored, it is directly sent to the vehicle. Otherwise, the differential update package between the two is calculated in real time based on the two complete software packages, and then distributed. Figure 8 A flow chart of a method for processing a vehicle update package is shown, wherein the method for processing a vehicle update package comprises the following steps:

[0139] S810: Obtain attribute data of each version of the software package.

[0140] S820: Determine a first candidate software package according to the usage frequency of each version of the software package.

[0141] S830: Determine a second candidate software package according to the version date of each version software package.

[0142] S840: Determine the target software package according to the first candidate software package and / or the second candidate software package.

[0143] S850: Generate and store a corresponding differential update package for the target software package.

[0144] S860: In response to receiving an update instruction from a vehicle, determining a first identity identifier of an old software package to be updated and a second identity identifier of a new software package to be updated; determining whether a differential update package between the old software package and the new software package is stored according to the first identity identifier and the second identity identifier; in response to a differential update package between the old software package and the new software package being stored, sending the differential update package to the vehicle; in response to a differential update package between the old software package and the new software package not being stored, calculating the differential update package between the old software package and the new software package online, and sending the differential update package to the vehicle.

[0145] Among them, the vehicle update instruction can be initiated by the vehicle or by the server. The old software package to be updated refers to the software package currently in use by the vehicle (assuming it is version A), and the new software package to be updated refers to the software package that the vehicle is preparing to install and use (assuming it is version B). The server first searches for the difference update package between version A and version B in the pre-stored difference update package. If so, the difference update package is directly read and sent to the vehicle. If not, the difference update package between the complete software package of version A and the complete software package of version B is calculated online. After the calculation is completed, the obtained difference update package is sent to the vehicle.

[0146] The first identity identifier and the second identity identifier may specifically be version numbers of a software package.

[0147] By pre-generating and storing corresponding differential update packages for target software packages with higher usage frequencies and newer version dates, when vehicles need to be upgraded, they can be directly read and distributed, saving the time consumed in calculating differential update packages, reducing user waiting time, and improving upgrade efficiency.
