Vehicle-mounted retrieval system, vehicle-mounted end and cloud service center

Abstract

The invention provides a vehicle-mounted retrieval system, a vehicle-mounted end and a cloud service center. The vehicle-mounted retrieval system comprises the vehicle-mounted end and the cloud service center. The cloud service center stores historical data of the vehicle-mounted end. The vehicle-mounted end sends a retrieval request carrying the current position information of the vehicle-mounted end and identity data of the vehicle-mounted end to the cloud service center. The cloud service center retrieves related historical data related to the identity data in the historical data of the vehicle-mounted end based on interest points in a retrieval preset area of the current position information and based on the identity data after the retrieval request is obtained and the identity data is confirmed to be valid. The cloud service end regards interest point data of the interest points matched with the related historical data as a retrieval result of the retrieval request and feeds the retrieval result back to the vehicle-mounted end. The vehicle-mounted end receives the retrieval result. The vehicle-mounted retrieval system, the vehicle-mounted end and the cloud service center improve retrieval efficiency of vehicle-mounted devices.

Description

technical field [0001] The invention relates to the technical field of vehicle systems, in particular to a vehicle retrieval system, a vehicle terminal and a cloud service center. Background technique [0002] Cars have been used as people's daily means of transportation for more than 120 years. During this period, with the development of technology, cars have also undergone rapid changes. With the continuous development and progress of automobile technology, vehicle-mounted equipment that can realize various functions, as an auxiliary product of automobiles, has gradually entered people's lives. [0003] For example, the navigation function of the car map provides great convenience for car users to find their way and destination. [0004] With the development of network technology, online shopping has gradually become the mainstream consumption channel, and the vehicle terminal has gradually realized the function for users to use the vehicle terminal system for online shop...

AI Technical Summary

Problems solved by technology

Due to the limited performance and resources of the in-vehicle terminal, when shopping online through the in-vehicle system, the system reads the product database of the merchant and retrieves the products in the product database. Due to the large number of products, it takes a lot of time and the speed is slow. , which greatly affects the user experience; moreover, the search is not targeted, resulting in the retrieved products not meeting the user's needs
