The invention discloses an unlocking and locking control method and system for an electronic steering lock, and relates to the technical field of domain controllers, and the method comprises the following steps: obtaining an unlocking and locking preparation state of a vehicle; when the obtained unlocking and locking preparation state of the vehicle is ready, performing signal interaction through a CAN message to execute bidirectional authentication between the vehicle body domain controller and the electronic steering lock controller to obtain a bidirectional authentication result; and when the bidirectional authentication is successful, controlling to execute unlocking and locking operations. Compared with the prior art in which communication is carried out between the vehicle body domain controller and the electronic steering lock controller through an LIN bus, the communication between the vehicle body domain controller and the electronic steering lock controller is realized through signal interaction by the CAN bus, so that the problems of overtime bus communication and wrong data transmission caused by voltage fluctuation or LIN bus interference are solved; and bidirectional authentication between the vehicle body domain controller and the electronic lock controller can be realized, and the anti-interference capability and the system safety of the electronic steering lock are effectively improved.

    本申请公开了电子转向锁解闭锁控制方法及系统,涉及域控制器技术领域,方法包括如下步骤:获取车辆的解闭锁准备的状态;当获取的车辆的解闭锁准备状态就绪时,控制通过CAN报文进行信号交互执行车身域控制器和电子转向锁控制器之间的双向认证获取双向认证结果;当双向认证成功时,控制执行解闭锁操作。本申请通过CAN总线进行信号交互实现车身域控制器和电子转向锁控制器之间的通信,相比于现有技术中车身控制器和电子转向锁控制器之间通过LIN总线进行通信,不会出现电压波动或LIN总线干扰导致的总线通信超时和数据传输错误的问题,并且可以实现车身域控制器和电子锁控制器之间的双向认证,有效提升电子转向锁的抗干扰能力和系统安全性。
