Abstract
The utility model provides a vehicle anti-theft system comprising a vehicle body control module, an engine control module, a starting button and a keyless control module. The vehicle body control module drives the keyless control module to detect an intelligent key according to a starting signal of the starting button; the engine control module sends a verification code to the keyless control module after powered on, and checks the code after receiving the verification code fed back by the keyless control module and relieves or keeps the anti-theft state of an engine according to the result of code check; and the keyless control module judges whether the legitimate intelligent key is detected in powering on after receiving the verification code sent by the engine control module, and verifies the verification code sent by the engine control module under the condition of detecting the legitimate intelligent key and feeds back a verification code of the keyless control module self. The vehicle anti-theft system has high safety and reduces the risk that the vehicle is stolen.
Description
Technical field
The utility model relates to a kind of Vehicle Anti-Theft System.
Background technology
Along with the raising that people require vehicle safety, the vehicle anti-theft technology is arisen at the historic moment.Vehicle with anti-theft feature promptly allows to enter in the vehicle, does not obtain legal checking, also can't be with vehicle launch.Improve vehicle safety so greatly, reduced stolen risk.Present Vehicle Anti-Theft System is provided with Body control module, engine control module, no key control module and starter button cooresponding with it usually, press starter button, starter button sends cranking signal to Body control module, Body control module sends authentication request according to cranking signal to no key control module, to carry out the authentication of Intelligent key; If Intelligent key is legal, then Body control module sends the initiated innovation request to engine control module, and the permission cranking signal that sends according to engine control module starts the starter operation, when engine speed reaches start request, engine control module will be controlled driving engine oil spout igniting, and driving engine will be started.In the above-mentioned Vehicle Anti-Theft System, when engine speed reaches start request, engine control module will be controlled driving engine oil spout igniting, and some professional thieves only need power on starter by some method can finish the starting of driving engine, so this anti-theft system safety is lower.
The utility model content
Technical problem to be solved in the utility model provides the higher Vehicle Anti-Theft System of a kind of safety, needs between the engine control module of this Vehicle Anti-Theft System and the no key control module removing the anti-theft state of driving engine after the sign indicating number success.
The utility model is achieved through the following technical solutions: a kind of Vehicle Anti-Theft System comprises the Body control module that is controlled to be the power supply of finished vehicle electronic parts, engine control module, the start button that links to each other with Body control module of control driving engine oil spout igniting and the no key control module of verifying the Intelligent key legitimacy; Described Body control module is surveyed Intelligent key according to the no key control module of actuation signal driving of start button, and is controlled to be the power supply of finished vehicle electronic parts; Described engine control module, send identifying code in the back that powers on to no key control module, wait for no key control module feedback identifying code, and behind the identifying code of receiving no key control module feedback, carry out sign indicating number, and remove or maintenance engine anti-theft state according to result to sign indicating number; Described no key control module, after receiving the identifying code that engine control module is sent, then judge and whether detected legal Intelligent key when powering on, if detected legal Intelligent key, then the identifying code that engine control module is sent is verified, and the identifying code of feedback no key control module oneself is given engine control module; Do not have the key control module during if power on and do not detect legal Intelligent key, then do not have the key control module and the identifying code that engine control module sends is not verified, and can not feed back the identifying code of no key control module oneself.
According to Vehicle Anti-Theft System of the present utility model, even engine speed reaches the startup requirement, when the anti-theft state that still can't remove driving engine between engine control module and the no key control module to sign indicating number when unsuccessful, driving engine can not lighted a fire in oil spout, therefore can't start the engine, greatly reduce the stolen risk of vehicle.
