 System description (hidden door handle)系统说明(隐藏式门把手)

Function introduction功能介绍
The hidden door handle realizes the retraction and expansion of the hidden door handle by the forward and reverse rotation of the motor in the door handle mechanism. At the same time, there is a position sensor inside the mechanism to identify whether the door handle is currently in an expanded or retracted state. The IBCM is responsible for processing the control logic of the door handle expansion and retraction and sends it to FLDCM&FRDCM for driving through the CAN bus. FLDCM is responsible for driving the left front door handle and left rear door handle, and FRDCM is responsible for driving the right front door handle and right rear door handle.隐藏式门把手通过门把手机构内的电机正反转来实现隐藏式门把手的回缩和展开，同时，机构内部还有位置传感器来识别门把手当前是处于展开还是回缩的状态IBCM负责处理门把手展开和回缩的控制逻辑并通过CAN总线发送给FLDCM&FRDCM进行驱动，FLDCM负责驱动左前门把手和左后门把手，FRDCM负责驱动右前门把手和右后门把手。
Hidden door handle does not work隐藏式门把手不能动作
When the hidden door handle cannot operate:当隐藏式门把手不能动作时：
1. First, check whether the door handle is stuck, frozen or other external forces that prevent it from moving;首先应排查门把手是否存在卡滞、结冰等外力导致无法动作；
2. Secondly, check whether the door handle motor and mechanism are faulty, or whether there is an open circuit or short circuit in the wiring harness between the door handle motor and FLDCM&FRDCM;其次再排查门把手电机、机构是否存在故障，或门把手电机与FLDCM&FRDCM之间的线束是否存在开路或短路；
3. Once again, you can check whether the communication between the FLDCM & FRDCM that drives the door handle and the IBCM is normal. You can check it through the CAN bus tool, or you can judge whether the door lock, window and other parts of the door can work normally.再次可排查驱动门把手的FLDCM&FRDCM与IBCM之间的通讯是否正常，可以通过CAN总线工具进行检查，也可以通过该门的门锁、车窗等部件是否能正常工作来判断。
