Detailed Description
The following description is of some of the several embodiments of the invention and is intended to provide a basic understanding of the invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of the invention.
Fig. 1 is a schematic view showing a vehicle theft proof verification method according to an embodiment of the present invention.
As shown in fig. 1, a vehicle theft verification method according to an embodiment of the present invention is implemented by a fingerprint recognition device 100, a theft prevention controller 200, and a motor controller 300. The vehicle theft proof verification method illustrated in fig. 1 is a verification method applied to an electric vehicle, and is implemented by the motor controller 300, and if applied to a fuel vehicle, the motor controller 300 is replaced with an engine controller. The following description will be given taking the case of an electric vehicle as an example.
As shown in fig. 1, a vehicle theft verification method according to an embodiment of the present invention includes the steps of:
fingerprint presetting step S100: the fingerprint identification device 100 acquires a fingerprint for the first time and matches and stores the fingerprint with a corresponding car key, for example, when a driver enters a car for the first time;
a fingerprint verification step S200, in which a driver touches a fingerprint identification device 100 in the vehicle, the fingerprint identification device judges whether the fingerprint identified this time is matched with a fingerprint preset in the fingerprint identification device 100, if the fingerprint identification device 100 judges that the fingerprint identified this time is matched with an input fingerprint, the fingerprint is legal and enters a first anti-theft verification step S300, if the fingerprint is judged not to be matched with the input fingerprint, the fingerprint is illegal, the whole verification process fails and the process is ended;
a first theft-proof checking step S300: performing a first anti-theft check between the fingerprint identification device 100 and the anti-theft controller 200, if the first anti-theft check is legal, continuing a second anti-theft check step S400 described below, otherwise, failing the whole check process and ending the process; and
a second anti-theft verification step S400: a second check is performed between the antitheft controller 200 and the motor controller 300, if the second antitheft check is legal, it indicates that the antitheft controller 200 is a real antitheft controller (not an antitheft controller simulated by a hacker, for example), if the second antitheft check is successful, the motor controller or the engine controller allows the vehicle to start or allows the gear shift, that is, the whole check process is successful, otherwise, the whole check process is failed and the process is ended.
In the fingerprint presetting step S100, the fingerprint identification device 100 first obtains a fingerprint and matches the fingerprint with a corresponding car key, for example, the fingerprint is stored as a car key, of course, a driver may enter fingerprints of multiple fingers, for example, a thumb and an index finger, or the car may be used by multiple drivers, so that the multiple drivers may respectively enter the fingerprint when entering the car for the first time, and store the fingerprint as corresponding car keys.
In addition, the fingerprint recognition device 100 is preferably installed in a place in the vehicle where it is easy and not misactivated by the driver, such as a shift knob, or a one-touch start button.
In the first anti-theft verification step S300, anti-theft verification between the fingerprint identification device 100 and the anti-theft controller 200 is performed, and the verification method may be, for example, one-way or two-way verification based on AES, but is not limited to this verification method.
Next, a verification algorithm of the first anti-theft verification step S300 is described as an example.
Fig. 2 is a flowchart showing an example of the first theft proof check step.
As shown in fig. 2, it is indicated in step S1 that the fingerprint authentication has been passed;
in step S2, authentication request data 1 is transmitted from the fingerprint identification device 100 to the antitheft controller 200;
in step S3, the antitheft controller 200 verifies the request data 1;
in step S4, authentication request data 2 is transmitted from the antitheft controller 200 to the fingerprint identification device 100;
in step S5, the grain identification device 100 verifies the request data 2;
in step S6, authentication request data 3 is transmitted from the fingerprint identification device 100 to the antitheft controller 200;
in step S7, the antitheft controller 200 verifies the request data 3;
in step S8, in the case where the verification passes, a message that the verification is successful is transmitted from the antitheft controller 200 to the fingerprint recognition device 100.
After the first anti-theft verification step S300 is successfully verified, a second anti-theft verification step S400 is performed, and in the second anti-theft verification step S400, verification between the anti-theft controller 200 and the motor controller 300 is performed, for example, in a one-way or two-way verification based on AES, but not limited to this verification.
Next, a verification algorithm of the second theft prevention verification step S400 is described as an example.
Fig. 3 is a flowchart showing an example of the second theft proof check step.
As shown in fig. 3, it is indicated in step S11 that the authentication between the fingerprint recognition device 100 and the antitheft controller 200 has been passed;
in step S12, authentication request data 1 is transmitted from the antitheft controller 200 to the motor controller 300;
in step S13, the motor controller 300 verifies the request data 1;
in step S14, authentication request data 2 is transmitted from the antitheft controller 200 to the antitheft controller 200;
in step S15, the antitheft controller 200 verifies the request data 2;
in step S16, authentication request data 3 is transmitted from the antitheft controller 200 to the motor controller 300;
in step S17, the motor controller 300 verifies the request data 3;
in step S18, in the case where the verification passes, a message indicating that the vehicle is permitted to start or the electric vehicle is permitted to shift is transmitted from the motor controller 300 to the antitheft controller 200.
As described above, the vehicle theft verification method according to the present invention can authenticate with the theft prevention controller by replacing the vehicle key with the fingerprint, whereby the driver can unlock and perform the theft prevention controller authentication without wearing the vehicle key, and in the case where the authentication is passed, the vehicle is allowed to start (for example, the electric vehicle is allowed to shift gears). Moreover, the vehicle key and the fingerprint information are matched (and a plurality of fingerprints can be recorded) only when the vehicle key and the fingerprint are recorded for the first time, and the vehicle can be driven without carrying the key afterwards.
