Drawings
FIG. 1 is a flow chart of an electronic shift vehicle type mechanical locking anti-theft method according to the present invention.
Fig. 2 is a diagram illustrating mathematical operations.
Detailed Description
The method of the invention comprises the following steps:
the anti-theft device cancels the locking hardware of the steering column, increases the anti-theft certification of a vehicle body control unit and a gear shifting controller, and meets the performance requirement of the anti-theft device of the automobile GB 15740.
The vehicle body control unit is a vehicle control module and has the functions of: the storage part of the 'root key' of the vehicle and the authentication of the 'gear shifting controller' is involved.
The 'gear shifting controller' is an authenticated part, and if the authentication is unsuccessful, the gear shifting can not be carried out, namely, the vehicle can not be driven, so that the safety is ensured (the vehicle is not stolen).
The anti-theft authentication process comprises the following steps:
the driving cycle begins, the gear shifting controller actively initiates anti-theft authentication with the vehicle body control unit, and if the authentication is successful, the gear shifting controller allows the vehicle to be used by gear shifting; if the authentication fails, the gear shifting controller does not allow the gear shifting to use the vehicle, and sends anti-theft authentication failure information to the whole vehicle instrument to prompt that the whole vehicle is not anti-theft.
The gear shifting controller and the vehicle body control unit are two parts with different functions, the gear shifting controller controls the vehicle to switch gears, and the vehicle body control unit controls a vehicle door lock, light, a skylight, a key and the like.
The invention adds the anti-theft authentication of the gear shifting controller and the vehicle body control unit.
When a user starts the vehicle, the shift controller needs to actively request and identify (anti-theft) the body control unit.
The invention establishes the identity authentication relationship between the vehicle body control unit and the gear shifting controller through the anti-theft authentication process. Finally, a part, namely steering column locking hardware, is eliminated, so that the cost of the whole vehicle is reduced.
When the whole vehicle leaves a factory, the same secret key is written in two parts of the gear shifting controller and the vehicle body control unit. When the user uses the vehicle and starts authentication, the shift controller sends a seed (i.e., a string of random numbers) to the "body control unit", and performs a complex mathematical operation based on the key and the seed, such as the operation shown in fig. 2, to obtain a result a. And the vehicle body control unit performs the same complex mathematical operation according to the same secret key and the same seed to obtain a result B, and sends the result B to the gear shifting controller. And the gear shifting controller compares the self-calculated result A with the received result B, if the self-calculated result A is consistent with the received result B, the anti-theft authentication result passes, and if the self-calculated result A is inconsistent with the received result B, the anti-theft authentication result does not pass.
The vehicle body control unit performs the same mathematical operation on the received seeds and the secret keys to obtain a result B, and the result B is sent back to the gear shifting controller. And the gear shifting controller compares the results A and B, if the results A and B are consistent, the identity authentication is successful, the anti-theft authentication is passed, and the passed result information is sent to the vehicle body control unit through the vehicle body CAN bus.
The fact that the whole vehicle is not stolen means that the result A and the result B are different in comparison, and the two identity authentication results are not successful. The vehicle will not be able to be used (gear change).
It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
