Automobile electronic key and method thereof, automobile controller and method and system thereof

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.
