Problems solved by technology

However, the inventor's investigation and research found that the error in the learning process is mainly due to the uncertainty of the radio signal propagating in the air when the smart key sends the key information to the car through a high-frequency signal, which in turn causes the car to make an error in the key learning process.

[0020] Please refer to figure 1 , figure 1 A flowchart showing a smart key learning method. The intelligent key learning method is applied to such as figure 2 The smart key learning system 300 is shown. The method comprises the steps of:

[0021] In step S101 , the off-line diagnosis electrical inspection device 100 judges whether the vehicle is the vehicle 200 to be learned.

[0022] In the present embodiment, if the car connected with the offline diagnosis electric inspection device 100 is not the car 200 to be learned, a learning failure report is generated and the flow process ends; The car 200 then proceeds to step S102. Avoid repeated learning of the vehicle 200 to be learned. Such as image 3 As shown, step S101 includes the following sub-steps:

[0023] In sub-step S1011, the off-line diagnostic electrical testing device 100 inquires whether there is an authentication key in the car.

[0024] In this embodiment, the authentication key may be a vehicle identif...

Abstract

The embodiments of the present invention provide an intelligent key learning method and an intelligent key learning system, and relate to the technical field of vehicle keys. The intelligent key learning method is used for the intelligent key learning system. The intelligent key learning system comprises an offline diagnosis electric inspection device and a vehicle to be learned, wherein the offline diagnosis electric inspection device and the vehicle to be learned form communication connection. The intelligent key learning method comprises that the offline diagnosis electric inspection deviceacquires an identification code corresponding to a target intelligent key according to a learning starting command; the identification code is identified so as to acquire the feature data of the target intelligent key; and the feature data of the target intelligent key is stored in a vehicle to be learned so as to complete the learning on the target intelligent key by the vehicle to be learned. According to the present invention, with the method and the system, the activation of the intelligent key is not required during the intelligent key learning, such that the learning time is reduced, the radio interference during the learning is avoided, and the learning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of car keys, in particular to a method and system for learning an intelligent key. Background technique [0002] In the high-tech era, the function of the car key is no longer just to open and close the door and start the engine. The traditional key unlocking function has been gradually replaced by the keyless entry and start system (PEPS). As the function of the user identification card, the smart key establishes low-frequency and high-frequency two-way communication with the PEPS host in the whole system, and can unlock the door or start the engine after passing a series of authentications. The characteristic information of each smart key is unique. When each car leaves the factory, it needs to establish a one-to-one correspondence with the key, and the process is called the key learning process. [0003] Manufacturers continue to shorten and increase the speed of car learning in pursuit of production ef...
