Embodiment Construction

[0080] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0081] Now the industry generally has low requirements for the network quality of the Internet of Vehicles, and the overall QoS (network quality of service) of the network operators for the Internet of Things links is also low. However, with the development of various music and video entertainment applications on the mobile Internet, users The requirements for the entertainment experience of the large screen of the Internet of Vehicles are getting higher and higher.

[0082] In addition, OTA download technology has now become an essential service in the era of contemporary smart cars, and an important feature of OTA is that a relatively large image file needs to be downloaded by the vehicle terminal. Therefore, during the OTA rele...

Abstract

The embodiment of the invention provides a vehicle over-the-air OTA processing method and device, a server is in communication connection with a vehicle, and the method comprises the steps: obtainingroad network quality distribution information and vehicle historical information; according to the road network quality distribution information and the vehicle historical information, determining a scheduling strategy of a time period and a road section for respectively pushing a preset upgrading file to a plurality of vehicles; calculating a first charge required for OTA downloading by the plurality of vehicles according to the scheduling strategy; and determining a called charging interface for OTA downloading according to the first charge. According to the invention, road network quality distribution information and vehicle historical information of each vehicle are used, the scheduling strategy for pushing the preset upgrading file and the called charging interface for OTA downloadingare determined respectively, and the resource cost of an enterprise is reduced according to the called charging interface while the reasonable utilization rate of bandwidth flow is increased according to the determined scheduling strategy.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle over-the-air OTA processing method and a vehicle over-the-air OTA processing device. Background technique [0002] According to the definition of the China Internet of Things School-Enterprise Alliance, the Internet of Vehicles (Internet of Vehicles) is a huge interactive network composed of information such as vehicle location, speed, and route. Through GPS (Global Positioning System, Global Positioning System), RFID (Radio Frequency Identification, radio frequency identification), sensors, camera image processing and other devices, vehicles can complete the collection of their own environment and status information; through Internet technology, all vehicles can Its own various information transmissions converge to the central processing unit; through computer technology, the information of these large vehicles can be analyzed and processed, so as to calculate the bes...
