Abstract
The invention relates to the field of plug-in hybrid vehicles, in particular to an anti-theft starting control method for a vehicle. A plug-in hybrid vehicle anti-theft method based on encryption of a gearbox comprises the steps that a vehicle body controller and a gearbox controller are included, and the vehicle body controller generates original data with an encryption data bit; the original data are processed through an encryption algorithm, so that encryption data are obtained; verification data are obtained through comparative calculation of the encryption data and a secret key; and the verification data are sent to the gearbox controller after a data message and a check code are added for the verification data, the gearbox controller checks the verification data through a check algorithm according to the secret key, the original data and the encryption algorithm, starting of a vehicle is allowed if the verification data pass the check, and starting of the vehicle is forbidden if the verification data do not pass the check. According to the plug-in hybrid vehicle anti-theft method based on encryption of the gearbox, an anti-theft validation method from the vehicle body controller to the gearbox controller is adopted, validation of a motor or an engine is omitted only, and the vehicle cannot be started by starting the motor or the engine manually so that violent disassembling can be effectively avoided, and anti-theft validation of the plug-in hybrid vehicle is achieved accordingly.
Description
Technical field
Start control method the present invention relates to the mixed dynamic vehicular field of plug-in, more particularly to a kind of vehicle anti-theft.
Background technology
In conventional fuel oil power, it is common to use the side of certification is encrypted by car body controller and engine controller
Formula, to ensure that engine controller only starts engine after correct information is received, and allows to drive vehicle.Go out now
In existing plug-in hybrid dynamic system, such as the plug-in motor vehicle driven by mixed power based on P2 structures, because engine and motor have
Make the possibility of vehicle traction, as long as pulling out the electric wire below ignition switch, then line is picked up, after car engine
Just take away, at this moment just can be start, existing antitheft mode cannot correspond to the robber garage that this violence disassembles and be.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of mixed dynamic anti-stealing method for vehicles of the plug-in of gearbox encryption, should
Method is moved using the antitheft authentication mode from car body controller to gearbox control because gearbox is that dynamical system is final
Power output mechanism, therefore individually bypassing motor or the certification of engine cannot all start car or, manually booting motor or engine
, violence can be prevented effectively from and disassembled, it is achieved thereby that the antitheft certification of the mixed motor-car of plug-in, improves the reliability of antitheft certification
Property.
What the present invention was realized in：A kind of mixed dynamic anti-stealing method for vehicles of the plug-in of gearbox encryption, including Body Control
Device and gearbox control, comprise the following steps：Setting key, encryption data position, AES and checking algorithm；
S1. the car body controller is endowed an initial data for encryption data position；
S2. initial data process with AES obtaining encryption data；
S3. it is compared with encryption data and key and is calculated checking data；
S4. to be sent to gearbox control after checking data interpolation data message and check code, gearbox control is according to close
Key, initial data and AES are verified using checking algorithm to checking data, and verification is allowed to start by then vehicle,
Verification is not by then vehicle No starting.
The encryption data position is 64 or 128.
The AES is to the left or to move right 3~5 by initial data is overall in encryption data position, it is mobile after go out
Mend 0 in existing room.
The checking algorithm is verified for CRC16.
In the step S3, it is described compare be calculated as with calculate or XOR calculate.
The mixed dynamic anti-stealing method for vehicles of plug-in of gearbox encryption of the present invention is used from car body controller to gearbox control
Antitheft authentication mode, because gearbox is the final power take-off mechanism of dynamical system, therefore individually bypasses motor or start
The certification of machine cannot all start vehicle or, manually booting motor or engine, can be prevented effectively from violence and disassemble, it is achieved thereby that inserting
The antitheft certification of the mixed motor-car of electricity, improves the reliability of antitheft certification.
Brief description of the drawings
Fig. 1 is the control logic block diagram that the plug-in that gearbox of the present invention is encrypted mixes anti-stealing method for vehicles.
Specific embodiment
With reference to specific embodiment, the present invention is expanded on further.It should be understood that these embodiments are merely to illustrate the present invention
Rather than limitation the scope of the present invention.In addition, it is to be understood that after the content for having read statement of the present invention, people in the art
Member can make various changes or modifications to the present invention, and these equivalent form of values equally fall within the application appended claims and limited
Scope.
Embodiment 1
Such as Fig. 1, a kind of mixed dynamic anti-stealing method for vehicles of the plug-in of gearbox encryption, including car body controller and gearbox control,
Comprise the following steps：Setting key, encryption data position, AES and checking algorithm；
S1. the car body controller is endowed an initial data for encryption data position；The initial data manufacture when with
Machine is recorded as fixed value after assigning；In the present invention, the encryption data position is 64 or 128.
S2. initial data process with AES obtaining encryption data；
S3. it is compared with encryption data and key and is calculated checking data；In the present embodiment, it is described as having preferably
Compare and be calculated as with or calculate or XOR calculating；
S4. to be sent to gearbox control after checking data interpolation data message and check code, gearbox control is according to close
Key, initial data and AES are verified using checking algorithm to checking data, and verification is allowed to start by then vehicle,
Verification is not by then vehicle No starting；In the present embodiment, the checking algorithm is CRC16 verifications.
In the present embodiment, the AES is to the left or to move right 3 by initial data is overall in encryption data position
~5, the room occurred after movement mends 0.
During specific implementation, the AES compares calculating using same or calculating from moving to left 5；Initial data is 8
Byte is all 1；8 raw bytes of byte are complete 1 i.e. 255,255,255,255,255,255,255,255.8 bytes are moved to left
5 and will room mend 0 after become 255,255,255,255,255,255,255,224.In the present embodiment, the key of selection is 8
The key of individual byte is 255,255,255,255,255,255,255,255.Being verified data after or calculating same with key is
255,255,255,255,255,255,255,224.Then for checking data header adds two data messages of byte, afterbody
Two check codes of byte of addition, data message is 37,82, and the CRC16 check codes of 10 bytes after interpolation data message are
190,119.It is 37,82,255,255,255,255,255,255,255,224,190 so to need 12 bytes for sending,
119.Receiving terminal receive after data by CRC16 verify it is errorless after, to 255,255,255,255,255,255,255,224 this
8 data of byte are reduced using key 255,255,255,255,255,255,255,255 and obtain 255,255,255,255,
255,255,255,224.Then 5 are moved to right.Mend 1 in room.So obtain 255,255,255,255,255,255,255,255 this
8 initial data, with the success of initial data comparison match, gearbox control allows vehicle launch.
