Embodiment Construction

[0026] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0027] figure 1 It shows a block diagram of a communication matching verification system for a car electronic key according to an embodiment of the present invention. Such as figure 1 As shown, the system may include a car electronic key 1 and a car controller 2 . The car controller 2 can perform communication matching with the electronic key 1 to write a communication key into the electronic key 1 , and the communication key can be used to replace the initial key of the electronic key 1 .

[0028] In the present invention, the term "initial key" refers to the key preset in the electronic key 1 and the car controller 2 before communication matching, and the i...

Abstract

The invention discloses a communication matching verification method for an automobile electronic key, an automobile electronic key, a communication matching method for an automobile controller, an automobile controller used for communication matching with an automobile electronic key, and a communication matching verification system for an automobile electronic key. The communication matching verification method comprises the steps of detecting a self-recovery identification in the electronic key after the electronic key is in communication matching with the automobile controller, wherein the self-recovery identification is written in by the automobile controller and used for representing whether communication matching succeeds; resetting a communication key written in by the automobile controller in the electronic key into an initial key of the electronic key when it is detected that the self-recovery identification represents that communication matching fails, so that the electronic key can be in communication matching with the automobile controller again. In this way, the problem of resource waste caused when one-time matching fails and the electronic key can not be used again is solved.

Description

technical field [0001] The present invention relates to the field of automobile electronic keys, in particular to a communication matching verification method for automobile electronic keys, an automobile electronic key, a communication matching method for automobile controllers, and a communication matching method for automobile electronic keys. A car controller, and a communication matching verification system for car electronic keys. Background technique [0002] With the continuous development of modern automotive electronic technology and the rapid progress of electronic keys, smart key systems have been installed on many cars, which solves the inconvenience caused to users by directly using mechanical keys. [0003] In order to establish a secure one-to-one communication relationship, a communication matching process is required between the car electronic key and the car controller. The conventional communication matching process is as follows: the electronic key and ...
