Embodiment Construction

[0048] The specific implementation manner of the present invention will be described in more detail below with reference to schematic diagrams. The advantages and features of the present invention will be more apparent from the following description. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0049] As described in the background, in the prior art, generally, the vehicle and the smart key can realize data communication through Bluetooth connection, wireless connection and other means. Usually, in order to prevent the vehicle from being stolen, the vehicle and the smart key can only be connected within a certain preset distance, for example, 5m, 10m, 15m, etc., so as to realize data communication. However, criminals can use the function of signal repeaters to extend the network distance between two node...

Abstract

The invention provides a method for unlocking a vehicle through an intelligent key and an automatic unlocking method of the vehicle, and is applied to the technical field of vehicle relay attack prevention. The contradiction between the safety and the convenience of the keyless start system is handled by combining the scene matching of the user and the explicit authorization, so the scene matching ensures that a vehicle owner can still realize non-perceptual automatic unlocking in most use scenes, and the convenience of the keyless start system is met; meanwhile, the safe unlocking of the vehicle in a non-automatic unlocking scene can be achieved in an authorized unlocking mode, and then the keyless starting system is prevented from being subjected to relay attacks.

Description

technical field [0001] The invention relates to the technical field of preventing vehicle relay attacks, in particular to a method for unlocking a vehicle with a smart key and an automatic unlocking method for the vehicle. Background technique [0002] Signal relay attack is a common attack on automotive Bluetooth Peps (Passive Entry Passive Start, keyless start / entry) system. Usually, the normal working process of the car Bluetooth Peps system is: when the owner carrying the Bluetooth key (usually a smart key installed with the Peps system, a mobile phone, a bracelet and other terminal devices) approaches the vehicle within a preset distance, the vehicle's The control system recognizes the unlock signal sent by the Bluetooth key and automatically unlocks the door; when the vehicle senses that the Bluetooth key is far away from the vehicle through the Bluetooth signal, the door lock will automatically lock. [0003] However, criminals can use signal repeaters to prolong the...
