Automobile intelligent key control method and system thereof

Abstract

The invention relates to the technical field of automobile intelligent key control, in particular to an automobile intelligent key control method and a system thereof. The method comprises the steps that an automobile owner sets user information through an owner electronic terminal and sends the user information to a vehicle-mounted T-Box; the vehicle-mounted T-Box communicates with a passive entry & passive start (PEPS) controller according to the set information, generates a startup key, generates a verification code according to the startup key, and sends the verification code and vehicle information to the user electronic terminal; the user electronic terminal is connected with the vehicle-mounted T-Box through the verification code and the vehicle information within the prescribed time; and when the user electronic terminal is successfully connected with the vehicle-mounted T-Box, the vehicle-mounted T-Box sends the startup key to the PEPS controller, so that the PEPS controller controls an automobile to be unlocked, and a start button comes into effect. By the adoption of the automobile intelligent key control method and the system thereof, the using safety and reliability of the automobile intelligent key can be achieved when the automobile is let out.

Description

technical field [0001] The invention relates to the technical field of automobile intelligent key control, in particular to an automobile intelligent key control method and system thereof. Background technique [0002] The existing smart key system PEPS (PassiveEntry&PassiveStart), also known as keyless system, passive keyless entry and start system, is mainly composed of vehicle communication and control system and smart key RFID (Radio Frequency Identification) carried by the user for legal identification, also known as Composition of RFID, SmartKey or Fob. When the user enters the detection range of the vehicle with the smart key, the user only needs to directly pull the outer opening handle on the door or press the unlock button on the door handle, and the vehicle will actively identify and authenticate the legitimacy of the smart key. When the user enters the car, he only needs to press the start button, and the vehicle will actively identify and authenticate the smart...

Problems solved by technology

This invention patent application has the following disadvantages: 1) Unable to bind unknown electronic terminals, if the electronic terminal is lost, it needs to be re-bound; 2) The requirements for the terminal are high, especially the low-frequency antenna and high-frequency antenna increase the manufacturing cost of the car; 3 ) The car owner cannot effectively control the loaned vehicle; 4) The Bluetooth module on the car has power consumption problems. Although the Bluetooth module is low power consumption, it has an impact on the dark current of the vehicle; 5) Only users who bind mobile phones can use it, so Product promotion is difficult
