[0002] OTA (Over The Air) is a remote upgrade technology, which is widely used in the firmware upgrade of vehicle ECU equipment units. With the popularization of smart cars, the ECU firmware package is getting bigger and bigger, especially the size of the firmware package for large screens and instruments in vehicles. They are all hundreds of megabytes. If you do not control a large number of vehicles and request the server to download at the same time, it will cause huge traffic and bandwidth pressure on the server; and usually the cloud will use CDN (Content Delivery Network, content distribution network) technology to improve the upgrade package. download speed, while CDN traffic is generally charged by bandwidth, and the monthly peak value is used as the billable bandwidth. If there is no flow control, the instantaneous peak value will be very large in the case of large concurrent downloads, thereby increasing traffic costs.
[0003] The traffic limit for vehicle OTA upgrade is different from that of traditional Internet access. For OTA, once the update is opened to a user, the download and access of this user can no longer be restricted. Otherwise, the user experience will be seriously affected, but the user who opens the update is not Downloads will definitely be triggered, and downloading through CDN servers is more difficult to accurately count and limit traffic

no. 1 Embodiment

[0059] refer to figure 1 , the first specific embodiment of the present invention, a vehicle OTA upgrade current limiting control method, including the following steps:

[0060] The upgrade service module receives the version query request from the vehicle, and initiates a download window request to the flow control unit when there is an updated version;

[0061] The upgrade service module receives the download window request result returned by the flow control unit according to the number of currently idle available download windows, and determines whether to send a confirmation update result to the vehicle according to the download window request result;

[0062] The upgrade service module receives the update package download request from the vehicle, pushes the update package information to the vehicle after receiving the update package download request, and sends the download status of the vehicle to the flow control unit, which is used for the flow control unit to update ...

no. 2 Embodiment

[0074] refer to figure 2 , the second specific embodiment of the present invention, a vehicle OTA upgrade current limiting control method, including the following steps:

[0075] The flow control unit receives the download window request sent when the upgrade service module checks that there is an updated version according to the version query request of the vehicle; if the upgrade service module checks that there is no version update, it directly returns the result that there is no version update;

[0076] The flow control unit returns the download window request result to the upgrade service module according to the number of available download windows currently idle;

[0077] After the vehicle end confirms the upgrade according to the download window request result of the upgrade service module, the flow control unit updates and calculates the number of available download windows according to the download status of the vehicle end obtained after the upgrade service module p...

no. 3 Embodiment

[0088] refer to image 3 , the third specific embodiment of the present invention, a vehicle OTA upgrade current limiting control method, including the following steps:

[0089] The upgrade service module receives the version query request from the vehicle side, checks whether the version is updated, and initiates a download window request to the flow control unit when there is an updated version;

[0090] The flow control unit receives the download window request, and returns the download window request result to the upgrade service module according to the number of available download windows currently idle;

[0091] The upgrade service module receives the request result of the download window, and determines whether to send a confirmation update result to the vehicle according to the request result of the download window;

[0092] The upgrade service module receives the update package download request from the vehicle, pushes the update package information to the vehicle af...

Abstract

The invention discloses a vehicle OTA upgrade traffic limiting control method, a vehicle OTA upgrade traffic limiting control system and a vehicle OTA upgrade traffic limiting control apparatus, wherein the method comprises the following steps: an upgrade service module receives a vehicle side version query request, and initiates a downloading window request to a traffic control unit if an updateversion exists; the upgrade service module receives a request result returned back by the traffic control unit according to the number of the currently idle available downloading windows, and determines whether to send an acknowledgement update result to the vehicle side; the upgrade service module receives an update pack downloading request of the vehicle side, pushes update pack information to the vehicle side, and sends a downloading state of the vehicle side to the traffic control unit for update calculation for the number of the available downloading windows. According to the method, thesystem and the apparatus provided by the invention, concurrent downloading quantity is limited according to the currently idle windows, meanwhile, update adjustment for dynamic windows is executed, and influence on the overall throughput caused by occupation to the downloading windows by silent users is avoided. The vehicle OTA upgrade traffic limiting control method, the vehicle OTA upgrade traffic limiting control system and the vehicle OTA upgrade traffic limiting control apparatus provided by the invention can be widely used in the field of data processing.
