An anti-theft method and system based on electronic shifter

Abstract

The invention provides an anti-theft method and system based on an electronic shifter, belonging to the technical field of automobiles. It solves the problem that the anti-theft risk of the existing anti-theft system is low. The anti-theft method based on the electronic shifter includes the following steps: the on-board controller sends a password authentication request according to the user's identity key; the electronic shifter generates a random code when receiving the password authentication request, and then combines the random code with its internal password Combined to form a password authentication signal and send it to the on-board controller, the on-board controller processes the password authentication signal 1 and feeds back the password authentication signal 2; the electronic shifter performs password comparison and verification on the feedback password authentication signal 2. When the verification result satisfies the unlocking conditions, the P gear parking mechanism executes the gear unlocking to realize the normal gear shift; otherwise, the P gear parking mechanism locks the gear shift. An anti-theft system based on an electronic shifter is also proposed. The invention can reduce the risk of vehicle theft.

Description

Technical field [0001] The present invention belongs to the field of automotive technology, relates to an anti-theft method based on an electronic shifter and a system thereof. Background [0002] Auto anti-theft device is a device that is installed on the car and mated with the accessories or circuits on the car to prevent the vehicle from being stolen or to increase the difficulty of car theft. The early car anti-theft device to mechanical anti-theft device-based, mechanical anti-theft system mainly relies on locking clutch, brake, throttle, steering wheel or transmission gear and other important parts of the operation of the car to achieve anti-theft purposes, this anti-theft system principle is simple, the price is relatively cheap, in the early stage of automobile development is widely used. However, because each time it is troublesome to disassemble and assemble, it is not convenient enough to find a place to place it when it is not used, and the security is not good, it is...

AI Technical Summary

Problems solved by technology

[0005] 1. The behavior judgment process is relatively complicated, and the user’s operation sequence on the vehicle cannot always be the same. During the judgment, it is likely that the car cannot be started because the user’s actions cannot be matched, which brings inconvenience to the user.

[0006] 2. Judging by the operation sequence of pulling the handbrake, buckling the seat belt, stepping on the foot brake, and starting the ignition, if the thief's operation sequence is exactly the same as this, it will be difficult to prevent theft. The system is easy to be destroyed so that it cannot prevent theft, and the risk of the vehicle being stolen is relatively high
