Method, device and system for vehicle intelligent unlocking

Abstract

The invention provides a method, device and system for vehicle intelligent unlocking. The method in one embodiment comprises the steps that when a whole vehicle is in a locked state, antennas arranged on the vehicle are controlled to sent low-frequency signals; a first response signal returned when a vehicle intelligent key receives the low-frequency signals of the antennas is received, and the first response signal comprises the signal strength, detected by the vehicle intelligent key, of the antennas; the area where the vehicle intelligent key is located is determined according to the signal strength of the antennas in the first response signal; when the vehicle intelligent key is located in a meeting area, intelligent key pre-authentication is carried out on the vehicle intelligent key, and prompting information is sent after intelligent key pre-authentication succeeds; and when the vehicle intelligent key is close to an unlocking area, intelligent key authentication is carried out on the vehicle intelligent key, the whole vehicle is controlled to be unlocked after intelligent key authentication succeeds, and after the whole vehicle is unlocked, and when any vehicle door of the vehicle is in an opened state, the antennas are controlled to stop sending the low-frequency signals. According to the method, device and system for vehicle intelligent unlocking, the use experience of vehicle users is improved, and convenience is improved.

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...
