The invention discloses an active speed limiting system based on the fatigue state of a driver, which comprises a driver fatigue level analysis device, a sound-light alarm device, a speed limiting device and a vehicle speed sensor, wherein the driver fatigue level analysis device is used for analyzing the fatigue level of the driver, sending a sound-light alarm signal to the sound-light alarm device when the fatigue level of the driver is mild fatigue driving, and sending an activation instruction the speed limiting device when the fatigue level of the driver is deep fatigue driving; the speedlimiting device is used for activating itself through the activation instruction, intercepting an accelerator opening value signal sent to a vehicle-mounted computer ECU by an accelerator pedal position sensor in real time when the speed limiting device is in an activated state, and collecting the real-time speed of the vehicle through the vehicle speed sensor; when the real-time speed of the vehicle is less than or equal to the preset limiting speed, the intercepted accelerator opening value signal is forwarded to the vehicle-mounted computer ECU in real time; and when the real-time speed ofthe vehicle is greater than the preset limiting speed, an accelerator opening value signal corresponding to the limiting speed is sent to the vehicle-mounted computer ECU.

    一种基于驾驶员疲劳状态的主动限速系统,包括驾驶员疲劳等级分析装置、声光报警装置和限速装置和车速传感器;驾驶员疲劳等级分析装置用于分析驾驶员疲劳等级,当驾驶员疲劳等级为轻度疲劳驾驶时,向声光报警装置发送声光报警信号;当驾驶员疲劳等级为深度疲劳驾驶时,向限速装置发送激活指令;限速装置用于通过激活指令激活自身,当自身处于激活状态时,实时拦截加速踏板位置传感器发送给车载电脑ECU的油门开度值信号,并通过车速传感器采集车辆实时速度;当车辆实时速度小于等于预设的限制速度时,向车载电脑ECU实时转发拦截到的油门开度值信号;当车辆实时速度大于预设的限制速度时,向车载电脑ECU发送限制速度对应的油门开度值信号给车载电脑ECU。
