The invention belongs to the field of automobile safety control, and discloses a driver fatigue early warning system and early warning method.The system comprises a domain controller CEM, a communication module, an image acquisition module, an execution unit and a whole automobile control unit; the communication module, the image acquisition module and the whole vehicle control unit are all connected to the domain controller CEM, and the execution unit is connected with the whole vehicle control unit; the image acquisition module is used for acquiring head image information of a driver and sending the acquired head image information to the domain controller CEM, and the domain controller CEM is used for sending a mode switching signal to the whole vehicle control unit through the communication module to the execution unit when image information of a fatigue state is monitored. The battery management system BMS outputs the automobile output power to the whole automobile control unit and sends the automobile output power to the vehicle-mounted MCU through the whole automobile control unit, and the vehicle-mounted MCU receives the automobile output power and outputs the corresponding engine torque to reduce the automobile speed. Interference is carried out from two aspects of reminding and deceleration operation execution, and bidirectional early warning for a driver is realized.

    本发明属于汽车安全控制领域,公开一种驾驶人员疲劳预警系统及预警方法,所述系统包括域控制器CEM、通信模块、图像采集模块、执行单元和整车控制单元;通信模块、图像采集模块和整车控制单元均连接到域控制器CEM,执行单元连接整车控制单元;图像采集模块用于采集驾驶人员头部图像信息,并将采集到的头部图像信息发送到域控制器CEM,域控制器CEM用于在监测到疲劳状态的图像信息时,通过通信模块向整车控制单元发出模式切换信号到执行单元。电池管理系统BMS将输出汽车输出功率到整车控制单元,并经整车控制单元发送到车载MCU,车载MCU接收汽车输出功率,并输出对应发动机扭矩,降低车速。从提醒和执行减速操作两方面进行干预,实现对驾驶人员的双向预警。
