Method capable of realizing car security and theft prevention through a key control module

Abstract

The invention relates to a method of realizing car security and theft prevention through a key control module, particularly through cancelling an intelligent key to invalidate the intelligent key to realize car security and theft prevention. The present invention designs a key control module to be installed on the bus or the OBD diagunostic interface inside the car, thereby avoiding the risk that the cars maybe easily stolen. When the key control module 2 discovers the illegal entry into the car, the original intelligent key 5 inside the car is cancelled immediately through the car load CAN bus or OBD diagnostic interface, invalidating the original car intelligent key 5, thereby losing the control of the car. The aforementioned key control module 2, includes the signal reception module 21, the signal handling module 22, the intelligent key cancellation notification module 23, the door-window status detection module 24. The present invention utilizes the car load CAN bus and the OBD port, and manages the original car intelligent key kept inside the car through the installed key control module to judge whether the car has illegal entries, thereby preventing the car from being stolen; while preserving the conveniences of remote control cars, the car theft prevention and security are strengthened.

Description

technical field [0001] The invention relates to a method for realizing automobile safety and anti-theft by adding a key management module, in particular a method for realizing automobile safety and anti-theft by canceling the intelligent key and making the intelligent key invalid. Background technique [0002] In the Internet era where the demand for intelligent remote control of automobiles is becoming more and more popular, the demand for remote opening and closing of doors and remote start / stop of the engine has attracted more and more attention. However, most of the solutions now require an original car smart key to be placed in the car. To achieve these functions, this solution obviously has flaws, and there are hidden dangers in vehicle safety. The car may be pried open at any time or the glass may be broken. Thieves can enter the car and drive away directly, resulting in car theft. [0003] In order to solve this automobile safety problem, the present invention design...
