Detailed description of the invention
As shown in Figure 3, generation of the present invention drive schema management system comprise password input block 101, password encryption module 102, bus message sending module 103, bus 104 and generation drive schema management module 105.Described password input block 101 communicates to connect with described bus message sending module 103, the communication link between both is arranged password encryption module 102, and bus message sending module 103 is driven schema management module 105 through bus 104 and generation and communicated to connect.If bus 104 transmits the password of input in the mode of plain code, then password may be stolen easily, and therefore the setting of described password encryption module 102 is necessary.As can be seen here, essence of the present invention is, realizes generation and drives the startup of management mode by inputting the password that presets and it being transmitted in an encrypted form or exit.In addition, generation of the present invention drives schema management system preferably will be integrated with vehicle anti-theft control module 106 for driving schema management module 105 in Body control module, make can not enter when vehicle is stolen for driving pattern.
In generation of the present invention, drives the step of schema management method as shown in Figure 4, mainly comprises: first, and user inputs password (step 201) by password input block 101; Afterwards, the password of password encryption module 102 to input is encrypted, to form bus message (step 202); Next, described bus message is undertaken sending (step 203) by the predetermined transmission cycle by bus message sending module 103; The bus message sent transfers to for driving schema management module 105 (step 204) through bus 104; In generation, drives schema management module 105 and receives bus message and confirm whether effectively (step 205) this information; If bus message is effective, then in generation, drives schema management module 105 in bus 104, broadcasts the message starting for the pattern of driving/exit, to start/to exit generation driving pattern (step 206a), if bus message is invalid, then in generation, drives schema management module 105 and can not broadcast the message starting for the pattern of driving/exit in bus 104, and generation drives pattern and therefore can not start/exit (step 206b).
Preferably, drive the present age schema management module 105 integrated in Body control module with vehicle anti-theft control module 106 time, generation then in Body control module drives schema management module 105 not only will according to bus message, the current antitheft authentication scenario that also will provide in conjunction with vehicle anti-theft control module 106, determines whether the message that the broadcast generation pattern of driving starts/exits in bus 104.Now step 206a and 206b is replaced by following step 207a, 207b and 207c: namely, when vehicle anti-theft control module 106 provides correct car owner's key information (namely vehicle does not have stolen situation) and bus message is effective, in generation, drives schema management module 105 in bus 104, broadcasts the message starting for the pattern of driving/exit, to start/to exit generation driving pattern (step 207a); When vehicle anti-theft control module 106 provides correct car owner's key information (namely vehicle does not have stolen situation) but bus message is invalid, in generation, drives schema management module 105 and can not broadcast the message starting for the pattern of driving/exit in bus 104, thus can not start/exit for driving pattern (step 207b); When vehicle anti-theft control module 106 fails to provide correct car owner's key information (situation that vehicle is stolen), no matter whether bus message is effective, in generation, drives schema management module 105 and all can not broadcast the message starting for the pattern of driving/exit in bus 104, thus can not start/exit for driving pattern (step 207c).
Visible, in the generation that enforcement of the present invention does not need increase special, drives key; And in order to not increase new hardware resource, the parts comprised in system of the present invention can select the standard configuration of vehicle.Fig. 5 is block diagram generation of the present invention driving the preferred embodiment of schema management system.As shown in the figure, the digital keys on vehicle central control panel can be used as password input block 101 to input the password of digital form, central control panel itself is bus message sending module 103, password transmission to Body control module starts/exits for driving pattern as above-mentioned bus 104 by controller local area network (CAN) bus of vehicle, password encryption module 102 can adopt the form of counting machine, and other control modules in Fig. 5 are after acquisition Current vehicle generation drives the status information of pattern, enter/exit the associative operation specified for the pattern of driving.
Hereafter the preferred embodiment that generation of the present invention drives schema management method and management system is specifically described.
Central control panel is the vehicle bus unit of vehicle standard configuration, and its digital keys is generally used for radio station list and selects or the selection of CD song; And in the present invention, central control panel and digital keys thereof, except for except above-mentioned purpose, also carry the task that user drives the input of pattern password and the transmission of CAN information generation.
In order to ensure the safety and reliability of password in bus transfer process of input, drive in the above-mentioned steps 202 of schema management method in generation of the present invention, the password inputted the digital keys by pressing central control panel is encrypted, and is specifically described below.
Digital keys due to central control panel has two kinds of number of keys (6 keys or 9 keys), correspondingly, 1 or 2 bus message byte (Byte) can be used to encode, as shown in table 1.In each byte, last 2 (Bit) input as rolling code.Password encryption module 102 (in this case counting machine) sends the cycle according to predetermined bus message, after each transmission information, counting machine adds 1, again by Counter Value divided by 4 remainder numbers, numerical value can be obtained thus between " 00,01,10,11 " continuously and the code of circulation change.For the central control panel of 6 keys, front 6 difference these 6 buttons corresponding of its bus message byte, represent the password of real digital form; For the central control panel of 9 keys, the 4 to 6 difference these 9 buttons corresponding of front 6 and second the bus message bytes of first bus message byte, represent the password of real digital form.Owing to being enrolled among bus message by the rolling code constantly changed, so the information be presented in bus is constantly change, do not know that the people of coded system is difficult to the authentic password cracked wherein.
Table 1
The following description is all for the central control panel of 6 keys.Suppose that the currency of counting machine is 100, as can be seen from Table 2, when inputting " 1 " (from the #1 that pushes button to lifting), bus message can occurrence dynamics change " $ 04, $ 05, $ 06, $ 03 ".
Table 2
It may be noted that, bus message value herein adopts the binary-coded decimal of 16 systems to represent, Bit7 ~ Bit0 can be divided into Bit7 ~ Bit4 and Bit3 ~ Bit0 two sections, for the bus value " $ 04 " in table 2, " 0000 " of Bit7 ~ Bit4 represents the first " 0 ", " 0100 " of Bit3 ~ Bit0 represents and " 4 " of last position all adopts this method for expressing below.
In addition, due to the length possibility of key press time different (the above-mentioned bus message comprising varying number sends the cycle), the bus message value pressing same button also can change.Extend upon pressing the key, the bus message value then inputting " 1 " can become " $ 04, $ 05, $ 06, $ 07, $ 00 ", shorten upon pressing the key, the bus message value then inputting " 1 " can become " $ 04, $ 05, $ 02 ", (comprise 5 and 3 bus messages transmission cycles respectively, and the situation shown in table 2 comprises 4 bus messages transmission cycles) respectively as shown in Table 3 and Table 4.It is pointed out that the time of pressing a certain button can not exceed predetermined threshold value, when the threshold value is exceeded, can think to be seized button thus qualified information is invalid.
Table 3
Table 4
On the other hand, counting machine is cumulative, and when user inputs password again, because the initial value of counting machine there occurs change, the value of rolling code also can correspondingly change, and further ensures the safety of user password.Situation as shown in table 5, when user inputs password " 1 " again, the initial value of counting machine is " 102 ", and therefore the value of rolling code is " 02 ", thus bus message now from above shown in input password " 1 " time bus message different.
Table 5
According to above principle, link up now the situation seeing actual 4-digit number password.For password " 1234 ", table 6 and table 7 compared for the different bus message value that different button durations causes, and table 7 and table 8 compared for the different bus message value that different counting machine initial values causes.
Table 6
Table 7
Table 8
In generation, drives schema management module 105 after receiving bus message, according to the coded system of aforementioned bus message, can parse the password of current input, obtain current rolling code value simultaneously, rolling code should be the continuous of the scope that can not exceed " 00,01,10,11 " and the value of circulation change.
According to this principle, when the rolling code value that the bus message received obtains after resolving occurs saltus step or remains unchanged, can judge that Current bus information is invalid, the password mal obtained; When rolling code value is continually varying, but represent in bus message byte that the position of certain button (such as 30s) within the time exceeding aforementioned predetermined threshold represents all the time and be in input state, then can judge that Current bus information is normal, but this button may be stuck, the password mal obtained.
Known by above-mentioned analysis, rolling code is introduced to the password that the digital keys by central control panel inputs, and the password of rolling code and input is enrolled same CAN information byte, utilize the numerical value that rolling code constantly changes, make bus message produce change of rolling, solve safety issue during CAN transmission.Meanwhile, possess the feature of serial number by rolling code itself, improve the reliability of bus message transmission.
Fig. 6 is the detailed diagram of generation of the present invention driving the specific embodiment of schema management system, illustrated therein is generation to drive integrated in Body control module of schema management module and vehicle anti-theft control module.The antitheft authentication function of vehicle is by the security module in charge in Body control module, and it bears reading, the work such as identification and engine anti-theft certification of key information.When not considering that generation drives pattern, vehicle anti-theft control module is at reading key information and after judging that information is correct, divide two-way work, lead up to bus and engine control module mutual, carry out engine anti-theft certification, the numbering of key is then outputted to CAN by another road, arranges function for driver personalityization.
When vehicle is in for when driving pattern, although vehicle is not in the control of car owner, vehicle anti-theft authentication also must normally work, and generation drives pattern and should not have influence on vehicle anti-theft authentication function.Meanwhile, also need for pattern of driving the state obtaining vehicle anti-theft authentication, especially need the authentication scenario knowing current key, only have legal car key just can enter, maintain or exit for driving mode state.So in the present invention, generation drives schema management module to be needed in conjunction with current vehicle anti-theft authentication situation, and then show that its generation drives the definite state of pattern, and the message that the broadcast generation pattern of driving starts/exits in bus.
In newly-increased generation, drives the functional independence of schema management module in security module, does not affect the normal work of antitheft certification.Security module is at reading key information and after judging that information is correct, increases by a road key numbering and outputs to generation and drive schema management module.In generation, drives schema management module and only after acquisition key numbering, just can enter real mode of operation, namely can carry out working as the judgement that former generation drives mode state, and can receive and process the input of the bus message from CAN, to tackle the change that generation drives mode state.If security module judges that current is the invasion of illegal key, can not export key numbering, these epoch drive schema management module and can not work.
It can thus be appreciated that, in vehicle of the present invention generation, drives schema management system and will carry out integrated for driving schema management module and vehicle anti-theft authentication function, the situation guaranteed not affect vehicle anti-theft function and normally run, export and drive the enable signal of schema management by increasing by a road key numbering as generation, make also to be in the antitheft administrative measure of car load for pattern of driving, ensure that generation drives the safety of state.
The invention is not restricted to above-described specific embodiment, it will be understood by those skilled in the art that under the prerequisite not deviating from technical conceive of the present invention, can change above-described embodiment.Such as, the present invention not only may be used for generation drive pattern, other vehicle management patterns (pattern of such as hiring a car) can also be used for, extendability and application better.
