The invention discloses a voice recognition emergency braking system and method for an intelligent driving vehicle, relates to the technical field of voice recognition emergency braking, and solves the problem that when emergency braking is performed through voice recognition, the situation that in-vehicle volumes of different users have different characteristics in different time periods is neglected, and emergency braking is performed according to the different characteristics, so that the emergency braking efficiency is improved. And the technical problem of difficulty in self-optimization of the time period in division is solved. The method comprises the following steps: acquiring sound data when a vehicle runs; dynamically planning the time period of each day, analyzing the historical volume in the vehicle to obtain the characteristic volume of each time period in the vehicle, and obtaining a discrimination factor based on the characteristic volume, the volume in the vehicle, the personnel tone and the sound data outside the vehicle; obtaining a control instruction according to the personnel voice characters and the discrimination factor; the vehicle is braked based on the control instruction; according to the invention, the self-adaptability and accuracy of the voice recognition emergency braking system of the intelligent driving vehicle can be improved.

    本发明公开了一种智能驾驶车语音识别紧急制动系统及方法,涉及语音识别紧急制动技术领域,解决了在通过语音识别进行紧急制动中,忽视了不同用户在不同时间段中车内音量具有不同特征,并根据不同特征进行紧急制动,以及难以使时间段在划分中进行自我优化的技术问题;本发明通过获取车辆行驶时的声音数据;动态规划各天的时间段,对历史车内音量进行分析得到车辆内部各时间段的特征音量,基于特征音量、车内音量、人员音调和车外声音数据得到判别因子;根据人员语音文字和判别因子得到控制指令;基于控制指令对车辆进行制动;本发明能提高智能驾驶车语音识别紧急制动系统的自我适应性和准确性。
