The invention relates to a vehicle emergency state automatic identification and emergency braking auxiliary system which comprises a steering wheel pressure sensing module used for sensing the force of a driver holding a steering wheel, and when the detected sound decibel value exceeds a preset threshold value, an acoustic sensing module transmits a signal to a controller; when detecting that the force of holding the steering wheel by the driver exceeds a set threshold value, the pressure sensing module sends a signal to the controller; and when the detection results of the acoustic sensing module and the pressure sensing module simultaneously reach respective threshold values, the system enters an emergency braking state. According to the system, the current emergency situation is recognized through instinctive response of a driver, the braking response efficiency can be greatly improved, meanwhile, the misoperation risk under the emergency situation is reduced, and the traffic accident occurrence probability and the damage degree are reduced. A double-verification mode of voice recognition and pressure detection is adopted, whether the driver is in the critical moment or not can be accurately recognized, and the misjudgment risk is reduced.

    本发明涉及一种车辆危急状态自动识别与紧急制动辅助系统,所述系统包括方向盘压力感应模块用于感知驾驶员握紧方向盘的力度,当检测到的声音分贝值超过设定的预定阈值时,声学感应模块将信号传递给控制器,当检测到驾驶员握紧方向盘的力度超过设定的阈值时,压力感应模块会向控制器发送信号;当声学感应模块与压力感应模块的检测结果同时达到各自的阈值,系统进入紧急制动状态。该系统利用驾驶员的本能反应来识别当前的危急情况,可以大幅提高制动响应效率,同时降低危急情况下的误操作风险,减小交通事故发生概率与损伤程度。采用了语音识别和压力检测双重校验的模式,可以较为准确的识别驾驶员是否处于危急时刻,降低了误判风险。
