Method, device and system for intelligent unlocking of vehicles

Abstract

An intelligent vehicle unlocking method, device, and system. The method comprises: when an entire vehicle is in a locked state, controlling various antennae provided on the vehicle to send low frequency signals; receiving a first response signal sent by an intelligent vehicle key when receiving the low frequency signals sent by the various antennae, wherein the first response signal comprises signal strengths of the various antennae detected by the intelligent vehicle key; determining, according to the signal strengths of the various antennae in the first response signal, a location of the intelligent vehicle key; when the intelligent vehicle key is located within a guest welcoming area, performing intelligent key pre-verification on the intelligent vehicle key, and sending prompt information after verification is completed; and when the intelligent vehicle key is located near an unlocking area, then performing intelligent key verification on the intelligent vehicle key, and unlocking the entire vehicle after verification is completed, and controlling, after the entire vehicle is unlocked and a vehicle door is opened, the various antennae to stop sending the low frequency signals. Further disclosed is a device and system using the method. The method, device, and system improve user experience of a vehicle user and enhances convenience.

Description

technical field [0001] The invention relates to the field of vehicle intelligent control, in particular to a method, device and system for intelligently unlocking a vehicle. Background technique [0002] With the development of intelligent technology, the intelligent entry system of automobiles has been widely used in mid-to-high-end models. At present, the intelligent entry system of automobiles usually needs to be triggered by the intelligent entry button (or capacitive sensor) on the door handle. It takes a while from the button (or capacitive sensor) to be triggered until the door is unlocked. Generally, the one-way two-way communication time is greater than 100ms, and the two-way communication time is greater than 200ms. If the action of opening the door is too fast, it will be pulled because the unlocking is not completed. Do not open the door. Contents of the invention [0003] Based on this, the purpose of the embodiments of the present invention is to provide a m...
