Abstract
The present invention discloses a vehicle guard against theft and robbery cryptographic system includes a central controller and a data input and display equipment. The central controller is connected with the ECU of the vehicle, and stores several kinds of ciphers. Different kind of cipher corresponds to different work modes: if login with 'valid' cipher, the system will enter 'normal work mode', the user then can normally operate the vehicle; if login with 'guard against robbery' ciphers, the system will enter 'guard against robbery warning work mode', the user can operate the vehicle in a predetermined guard against robbery cipher valid period, but the central controller will send warning information to the user by wireless communication module; if the cipher submitted for many times is not matching with the cipher stored in the central controller, the system will enter 'guard against theft warning work mode' and trigger the warning device, and the user will not able to operate the vehicle. The invention makes the vehicle not only has reliable guard against theft ability but also has unique guard against robbery function.
Description
[technical field]
The invention belongs to the automobile technical field of security and protection, specifically is a kind of vehicle theft and robbery prevention password system.
[background technology]
Along with popularizing of automobile, steal that to rob the vehicle phenomenon serious day by day, present vehicle anti-theft technology roughly has three classes: the one, traditional burglar alarm, the survivability of this class device is very poor, security is low; Second class is the anti-theft device of controlled in wireless, this class device (as vehicle vibrations) easily affected by environment and produce wrong report, and this class device need additionally carry telepilot, and very inconvenient; The 3rd class is a fingerprint identification anti-theft device, this class apparatus structure complexity, cost is higher, and can't satisfy rents, by means of the theft-proof requirement of car.
In addition, the behavior of plundering vehicle now is also very rampant, and existing anti-theft technique all can't head it off.
[summary of the invention]
Purpose of the present invention just provides a kind of safe, and survivability is strong, does not have wrong report, need not telepilot, and the problem of robbing of meeting of stealing is met to solve automobile by the vehicle theft and robbery prevention password system with anti-theft and anti-robbing function easily and effectively.
The present invention is by the following technical solutions: the vehicle theft and robbery prevention password system, it is characterized in that: comprise central controller, data input and display device, described central controller is connected with original each ECU in the vehicle, store polytype password in the described central controller, described central controller is connected with wireless communication module, described central controller is connected with the vehicle location module, and described central controller is connected with warning device." legal " password of storing in the described central controller is used for the password of normal unlocking vehicle, management central controller etc., after the login of " legal " password, system enters " normal mode of operation ", the user can normally open driving vehicle, can revise the password of self, add, delete, revise " anti-snatch " password, effective work timing of " anti-snatch " password etc. is set; " anti-snatch " password of storing in the central controller is used for vehicle " chance is robbed " situation, when vehicle " chance is robbed ", after importing " anti-snatch " password and starting vehicle, system enters " robbing-proof alarm mode of operation ", the user is operating and controlling vehicle normally, but central controller will send warning message to designated user by wireless communication module, and when should " anti-snatch " password service time in case surpass default effective work timing, central controller will make vehicle show various faults and can't continue unlocking vehicle by original each ECU in the vehicle.When the password continuous several times of storing in the data of inputing in the data input device and the central controller does not conform to, system enters " burglar alarm mode of operation ", central controller makes vehicle show various faults by original each ECU in the vehicle and can't unlocking vehicle, and triggers warning device.
Advantage of the present invention is this cryptographic system and the design of vehicle control system one, and it is strong to have survivability, and cost is low, safe, characteristics easy to use, and make vehicle not only have remarkable anti-theft capability, more have unique anti-snatch function.
[description of drawings]
Fig. 1 is a hardware principle synoptic diagram of the present invention.
Fig. 2 is the FB(flow block) of realization vehicle theft and robbery prevention of the present invention.
[embodiment]
As shown in Figure 1, central controller 1 in the vehicle theft and robbery prevention password system is connected with display screen 2, timing device 4, password storage module 3, alarm 7 (warning device), data input device 8, wireless communication module 5 and vehicle location module 7, and various vehicle electronics control modules (ECU) also link to each other with central controller by the CAN bus transceiver.Wherein, display screen 2 and data input device 8 can replace with touch display screen.Vehicle location module 7 can be adopted the worldwide navigation locating module.
Fig. 2 has provided realization vehicle theft and robbery prevention FB(flow block), and concrete steps are as follows:
When vehicle transfers starting state to by flameout state, show on the display screen 2 " please input password " that the user verifies by " affirmation " key submission system after by the data input 8 input passwords being set.
Central controller judges that at first whether password that the user submits to is the password of " legal " type of being stored in the central controller, if the password of " legal " type, system enters " normal mode of operation ", central controller will send the instruction that allows use to each ECU by the CAN bus, and the user can normally open operating and controlling vehicle.
If password that the user submits to is not the password of " legal " type, whether the password that central controller is then judged the user again and submitted to is the password of " anti-snatch " type.If the password of " anti-snatch " type, system enters " robbing-proof alarm mode of operation ", central controller calculates the employed time of this password on the one hand whether above default effective work timing, in case surpass default effective work timing, central controller will send the withdraw from service instruction to fuel injection ECU by the CAN bus, vehicle will show as the oil piping system fault, thereby vehicle can't be travelled, even flame-out back with restarting vehicle by " anti-snatch " password, also is that fault remains unchanged; On the other hand; in the default effective work timing of this " anti-snatch " password; the user is operating and controlling vehicle normally; but during the time interval that every process is preset; central controller all will send warning message to the user of appointment by wireless communication module such as GPRS, and warning message comprises license plate number, per 5 minutes information such as vehicle location, report to the police thereby reach under the situation of protection car owner safety; the robber finally also can't seize vehicle by force, and the warning message that is sent provides certain for arresting the robber
If the user submitted to neither the password of " legal " type, neither " anti-snatch " password, central controller will at first be judged the wrong continuously number of times of submitting to of user, if number of times (as 3 times) less than appointment, then point out the user " password of input is wrong; please re-enter ", the user need re-enter password and submit the central controller checking to; Otherwise if the wrong continuously number of times of submitting to of user is greater than the number of times (as 3 times) of appointment, system enters " burglar alarm mode of operation ", central controller 1 makes each ECU unit all will not carry out various operations, thereby can't unlocking vehicle, and in the default time, will no longer verify, and send the warning message that comprises vehicle position information to the user of appointment by wireless communication module 5 (as GPRS) to the password of submitting to.
