Method for vehicle safety remote control and diagnosis and system thereof

Abstract

The invention provides a method for vehicle safety remote control and diagnosis and a system thereof. A control and diagnosis terminal and a cloud side instruction server perform first identity authentication and key agreement; a vehicle-mounted terminal and the cloud side instruction server perform second identity authentication and key agreement; and the control and diagnosis terminal establishes communication connection with the vehicle-mounted terminal through the cloud side instruction server and performs remote control or remote diagnosis on a vehicle according to the control and diagnosis instruction of a user. Different secret keys are adopted between the control and diagnosis terminal and the cloud side instruction server and between the vehicle-mounted terminal and the cloud side instruction server and so that the information security of remote control and diagnosis information can be guaranteed, and the problem of security insufficiency in the prior art can be effectively solved. The system for vehicle safety remote control and diagnosis has the advantages of being scientific in design, high in practicality, convenient and rapid, high in security and high in reliability.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to a method and system for remote control and diagnosis of vehicle safety. Background technique [0002] With the improvement of wireless network coverage, the popularization of various mobile terminals, the rapid development of intelligent technology, and the wide application of vehicle MCU or ECU, people's demand for intelligent vehicles is getting higher and higher. At present, for remote start vehicles, remote The remote control and remote diagnosis technology of vehicles such as switching vehicle air conditioners, remotely opening and closing windows, remotely driving vehicles, and remotely diagnosing vehicle faults have greatly facilitated people's use of vehicles, and also facilitated timely remote diagnosis and collection of vehicle information by vehicle manufacturers. [0003] However, while the remote control and remote diagnosis of vehicles bring convenience and practicalit...

AI Technical Summary

Problems solved by technology

[0003] However, while the remote control and remote diagnosis of vehicles bring convenience and practicality to people, there are also potential safety hazards that cannot be ignored.

For example, hackers or people with malicious attacks intercept the remote control commands of legitimate users and carry out replay attacks to control the vehicle; or steal the information between the user terminal and the vehicle terminal through network interception, so as to obtain the basic information and control commands of the vehicle , diagnostic instructions and diagnostic results, vehicle location, user information, etc., causing economic losses or other adverse effects to legitimate users or vehicle manufacturers
