The invention relates to systems and methods for detecting alertness of an occupant of a vehicle. Exemplary embodiments described in this disclosure are generally directed to systems and methods for detecting alertness of a driver of a vehicle. In one exemplary method, a driver alertness detection system determines whether a driver of a vehicle is susceptible to lagophthalmos. If the driver is susceptible to lagophthalmos, the driver alertness detection system may evaluate an alertness state of the driver by disregarding an eyelid status of the driver and monitoring biometrics of the driver such as, a heart rate and/or a breathing pattern. Alternatively, the driver alertness detection system may evaluate an alertness state of the driver by placing a higher priority on the biometrics of the driver than on the eyelid status. However, if the driver is not susceptible to lagophthalmos, the driver alertness detection system evaluates the alertness state by placing a higher priority on the eyelid status than on the biometrics of the driver.
本公开提供“用于检测车辆乘员的警觉性的系统和方法”。本公开中描述的示例性实施例总体上涉及用于检测车辆驾驶员的警觉性的系统和方法。在一种示例性方法中,驾驶员警觉性检测系统确定车辆驾驶员是否易患兔眼症。如果驾驶员易患兔眼症,则驾驶员警觉性检测系统可通过忽略驾驶员的眼睑状态并监测驾驶员的生物特征诸如心率和/或呼吸模式来评估驾驶员的警觉性状态。替代地,驾驶员警觉性检测系统可通过将驾驶员的生物特征置于比眼睑状态更高的优先级来评估驾驶员的警觉性状态。然而,如果驾驶员不易患兔眼症,则驾驶员警觉性检测系统通过将眼睑状态置于比驾驶员的生物特征更高的优先级来评估警觉性状态。
