The invention discloses an automobile instrument screen operation state monitoring method, an intelligent cabin and a vehicle thereof, and the method comprises the steps: periodically querying the operation state of an automobile instrument screen module MFD through an IIC communication protocol by using a microcontroller unit MCU in a cabin domain controller CSC; judging whether the message interaction between the MCU and the MFD is successful or not; and when the heartbeat signal is detected to be lost, the microcontroller unit MCU performs hard wire resetting on the automobile instrument screen module MFD through the hard wire IO. In conclusion, the requirement for the safety integrity level of the automobile is considered, the safety of the automobile in the running process is remarkably improved through accurate fault detection and timely recovery measures, the requirement for functional safety is met, potential accidents caused by instrument screen faults are reduced, and the safety of the automobile is improved. And higher-level safety guarantee is provided for drivers and passengers.

    本发明公开了一种汽车仪表屏运行状态监控方法、智能座舱及其车辆,方法步骤包括:利用座舱域控制器CSC中的微控制器单元MCU周期性地通过IIC通信协议查询汽车仪表屏模块MFD的运行状态,判断微控制器单元MCU与汽车仪表屏模块MFD之间的交互消息是否成功;当检测到心跳信号丢失时,微控制器单元MCU通过硬线IO对汽车仪表屏模块MFD进行硬线复位。综上所述,本发明考虑了汽车安全完整性等级的要求,通过精确的故障检测和及时的恢复措施,显著提高了汽车在运行过程中的安全性,不仅满足了功能安全的需求,而且通过减少因仪表屏故障导致的潜在事故,为驾驶员和乘客提供了更高级别的安全保障。
