    • An awake state estimation portion calculates an average steering angle, an average steering angular speed and a corrective steering angle on the basis of the steering angle acquired from a steering angle detection portion. The awake state estimation portion acquires the traveling speed of the vehicle from a vehicle speed detection portion. The awake state estimation portion corrects the calculated corrective steering angle by a correction value commensurate with the type of the traveling path on which the vehicle is traveling, and estimates the degree of the awake state of the driver on the basis of the post-correction corrective steering angle. Besides, the awake state estimation portion specifically determines the correction value commensurate with the type of the traveling path on which the vehicle is traveling, on the basis of at least one of the steering angle, the average steering angular speed and the traveling speed.
    • 唤醒状态估计部分基于从转向角检测部分获取的转向角来计算平均转向角,平均转向角速度和矫正转向角。 唤醒状态推定部从车速检测部获取车辆的行驶速度。 唤醒状态估计部通过与车辆行驶的行驶路径的类型相对应的校正值来校正计算出的校正转向角,并且基于校正后校正校正值来估计驾驶员的唤醒状态的程度 转向角。 此外,基于转向角,平均转向角速度和行驶速度中的至少一个,清醒状态估计部具体地确定与车辆行驶的行驶路径的类型相对应的校正值。

    • A blink detection section generates an eye-closure signal indicating the duration of a period for which the driver closes his/her eyes. An eye-closure count section calculates the respective occurrence frequencies of single eye closures in a prescribed measurement period for a first eye-closure period threshold and a second eye-closure period threshold, based on the eye-closure signal and the respective eye-closure period thresholds. A drowsy state determination section compares the respective occurrence frequencies with the first eye-closure frequency threshold and the second eye-closure frequency threshold to determine which of the drowsiness levels corresponding to the respective thresholds the drowsiness level of the driver is at.
    • 眨眼检测部分产生指示驾驶员关闭他/她的眼睛的周期的持续时间的闭眼信号。 闭眼计数部分基于闭眼信号和相应的眼睛闭合来计算针对第一闭眼周期阈值和第二闭眼周期阈值的规定测量周期中的单眼闭合的相应出现频率 期限阈值。 睡眠状态确定部分将各出现频率与第一闭眼频率阈值和第二闭眼频率阈值进行比较,以确定与驾驶员的嗜睡水平相对应的各个阈值中的哪一个嗜睡水平。
