The embodiment of the invention provides a vehicle key authentication method and device, a vehicle and a storage medium, the method is applied to a microcontroller, the microcontroller is arranged in the vehicle, a security element chip is further arranged in the vehicle, and the method comprises the steps that when a connection event of a vehicle key is detected, authentication for the vehicle key is initiated to the security element chip; obtaining an authentication result generated by the security element chip, and judging whether the security element chip is abnormal or not according to the authentication result; if the security element chip is abnormal, judging whether the vehicle key is legal or not; and if the vehicle key is legal, authenticating the vehicle key. Therefore, when the safety element chip is abnormal, the vehicle key can be authenticated through the microcontroller, the situation that when the safety element chip is abnormal, the vehicle key cannot be authenticated, so that a vehicle door cannot be unlocked and a vehicle cannot be started is avoided, and meanwhile the use experience of a user is improved.

    本发明实施例提供了一种车辆钥匙认证方法、装置、车辆和存储介质,该方法应用于微控制器,微控制器设置于车辆中,车辆中还设置有安全元件芯片,该方法包括:当检测到车辆钥匙的连接事件时,向安全元件芯片发起针对车辆钥匙的认证;获取安全元件芯片生成的认证结果,并根据认证结果判断安全元件芯片是否异常;若安全元件芯片异常,则判断车辆钥匙是否合法;若车辆钥匙合法,则对车辆钥匙进行认证。从而在安全元件芯片发生异常时,可以通过微控制器对车辆钥匙进行认证,避免在安全元件芯片出现异常时,无法对车辆钥匙进行认证,进而无法解锁车门和启动车辆,同时,也增加了用户的使用体验。
