建立声学指标以检测驾驶员头脑糊涂的系统和方法
Abstract:
本发明提供一种用于检测车辆内驾驶员的头脑糊涂状态的装置。该装置包含车辆界面装置，其被配置为接收来自于驾驶员的第一声音信号，该信号指示驾驶员处于非头脑糊涂状态时的至少一个单词，并且基于第一声音信号确定背诵至少一个单词的第一总时间。车辆界面装置被进一步配置为命令驾驶员背诵至少一个单词，以确定驾驶员的头脑糊涂状态，和接收来自于驾驶员的指示至少一个单词的第二声音信号。车辆界面装置被进一步配置为基于第二声音信号确定背诵至少一个单词的第二总时间，并且将第一总时间和第二总时间进行比较。
Abstract(English):

An apparatus for detecting an impairment state of a driver in a vehicle is provided. The apparatus comprises a vehicle interface device configured to receive a first audible signal from a driver indicative of at least one word while the driver is in a non-impaired state and to determine a first total time to recite the at least the word based on the first audible signal. The vehicle interface device is further configured to command the driver to recite the at least one word to determine the impairment state of the driver and to receive a second audible signal from the driver indicative of the at least one word. The vehicle interface device is further configured to determine a second total time to recite the at least one word based on the second audible signal and to compare the first total time to the second total time.
