Car keyless entry system based on proximity perception of a smartphone and control method

Abstract

The invention discloses a car keyless entry system based on proximity perception of a smartphone. The car keyless entry system comprises an information request module, a real-time positioning engine module, an information sending module, a vehicle-mounted device and a cloud platform, wherein the information request module, the real-time positioning engine module and the information sending moduleare arranged in the smartphone; the information request module is used for requesting information for the cloud platform; the real-time positioning engine module is used for realizing accurate and reliable space positioning of the smartphone relative to a car; the vehicle-mounted device includes a vehicle-mounted iBeacon base station, a vehicle-mounted bluetooth communication module, an information processing module, a car door controller module and an engine controller module, and the information processing module is used for induction-controlling a vehicle-mounted controller according to thechange of the spatial position information of a user relative to the car; the cloud platform is used for pre-storing UUID and MAC address information of the vehicle-mounted iBeacon base station of each car and a bluetooth fingerprint database and threshold information which correspond to each car type. According to the car keyless entry system, interference-free car entry control and location service are conducted through highly reliable human-car relative positioning.

Description

technical field [0001] The invention relates to automobile automation technology, in particular to an automobile keyless entry system and a control method based on proximity sensing of a smart phone. Background technique [0002] Existing cars are beginning to be equipped with a large number of keyless entry systems, which mainly use on-board equipment and smart keys to estimate the distance between the smart key and the car wirelessly, and realize authentication to provide convenience for drivers and passengers. With the popularization of smart phones and mobile Internet, using the communication capabilities, computing power and various built-in sensors of smart phones, a safe and reliable car keyless entry system can be realized through dynamic passwords and other methods. CN106379273A discloses an account management method for a car keyless system. Another key technology in the car keyless entry system is to estimate the mutual positional relationship between the smart k...
