Content delivery method and system through in-vehicle network based on regional content popularity

A content delivery method through an in-vehicle network, applied on the in-vehicle network of the target vehicle and a client of the target user in a target region, comprising

• based on an interaction between the target vehicle and other target vehicles within a preset communication range, calculating a delay that the target vehicle responds to the target user within the preset communication range and a success rate that the target user is responded to;
• based on the delay and the success rate that the target user is responded to, each content object contained in a cached content library of the target vehicle, and a cache ratio of the cached content library of the target vehicle, searching target content objects that match the target user in the cached content library;
• determining an utility that the target user is responded to by the target vehicle;
• and
• based on the utility that the target user is responded to by the target vehicle, optimally screening the target user responded to by the target vehicle, and establishing a set of target users responded to by the target vehicle;
• wherein the content objects contained in the cached content library of the target vehicle are determined by following method:
• extracting a data eigenvalue of a specified preset data type of each content object in the content library corresponding to the target region;
• based on the data eigenvalue of the specified preset data type of the content object, determining content objects that fall into the content category of each present type by means of self-organizing clustering;
• based on the content category and the data eigenvalue of the content object, determining the content category corresponding to all content objects, and determining the cache ratio of all content objects corresponding to the target vehicle under each content category;
• and
• inputting the content objects contained in each content category into the cached content library of the target vehicle.
