Vehicle anti-theft system and method based on V2X vehicle networking technology

Abstract

The invention discloses a vehicle anti-theft system and method based on the V2X vehicle networking technology. The vehicle anti-theft system comprises an anti-theft module, an intelligent vehicle-mounted unit, an intelligent drive test unit and a background service center. Starting is carried out within a preset time after the vehicle is shut down and powered off; the intelligent vehicle-mounted unit is used for authenticating the identity of a person in a main cab and identifying an intelligent vehicle key after the vehicle is restarted; the anti-theft module relieves the working state underthe conditions that the intelligent vehicle key identification is passed and the personnel identity authentication of the main cab is successful; and the intelligent vehicle-mounted unit sends a pre-alarm signal to the background service center under the conditions that the intelligent vehicle key identification is passed and the personnel identity authentication of the main cab is unsuccessful. The system overcomes the problem that in the prior art, a PKES is prone to being attacked by a relay, a relay signal is used for spoofing a vehicle, and therefore the purpose of stealing the vehicle isachieved, and the anti-theft performance of the vehicle cannot be guaranteed.

Description

technical field [0001] The present invention relates to the technical field of V2X Internet of Vehicles, in particular, to a vehicle anti-theft system and method based on the V2X Internet of Vehicles technology. Background technique [0002] With the improvement of people's requirements for vehicle safety, vehicle anti-theft technology has emerged as the times require. With the development of the automobile industry, customers have put forward higher and higher requirements for the convenience of smart keys on the premise of ensuring the safety of vehicles. Automobile intelligent keyless entry system, referred to as PKES (PASSIVE KEYLESS ENTER SYSTEM), means that the communication between the vehicle and the smart key can send a low-frequency signal through the vehicle, and the smart key returns a high-frequency signal after receiving the low-frequency signal, and passes the authentication in the signal Mechanism to achieve two-way communication and start the technology of ...

Problems solved by technology

[0003] However, in the prior art, PKES is vulnerable to relay attacks. Under normal circumstances, when the vehicle user closes the vehicle and goes out for errands, a third party can use the relay signal to deceive the vehicle, making the vehicle mistakenly believe that the user has sent a vehicle start signal And execute the vehicle to start, so as to achieve the purpose of stealing the vehicle, resulting in the anti-theft performance of the vehicle cannot be guaranteed
