    • The present invention relates to a lane marking crossing warning system (22) for a vehicle (1), the warning system (22) including a sensor arrangement (2) arranged to detect at least one lane marking line (5, 6, 7) that defines a corresponding lane boundary; a control unit (3) arranged to determine if the vehicle (1) has entered a curve (9, 9′); and warning means (13), arranged to issue a warning. When the control unit (3) has determined that the vehicle (1) has entered a curve (9, 9′), the control unit (3) is arranged to determine if an imaginary sensor line (8a, 8b) running a certain distance (11, 12) from the lane marking line (5, 6) has been crossed by the vehicle (1). If that is the case, the control unit (3) is arranged to determine that a warning is to be issued by the warning means (13).
    • 本发明涉及一种用于车辆(1)的车道标识交叉警告系统(22),所述警告系统(22)包括传感器装置(2),其被布置成检测至少一条车道标线(5,6,7) 定义相应的车道边界; 布置成确定车辆(1)是否已经进入曲线(9,9')的控制单元(3); 以及布置成发出警告的警告装置(13)。 当控制单元(3)确定车辆(1)已经进入曲线(9,9')时,控制单元(3)被布置成确定运行一定距离的虚拟传感器线(8a,8b) (11,12)已经被车辆(1)穿过。 如果是这种情况,则控制单元(3)被布置成确定由警告装置(13)发出警告。

    • A driver attentiveness detection device and method using at least one digital camera device (2) and a control unit (5). The camera device (2) is arranged to detect eye configurations of a vehicle driver (4). The control unit (5) compares the detected eye configurations with previously stored models of eye configuration samples (13, 14, 15, 16) which are indicative of eyes that look inside or outside a predetermined field of view (6). The control unit (5) further determines whether the detected eye configurations are looking inside or outside the predetermined field of view from the comparison, and is also arranged to indicate when the vehicle driver (4) has been determined to be looking outside the predetermined field of view (6) to a predetermined extent.
    • 一种使用至少一个数字照相机装置(2)和控制单元(5)的驾驶员注意力检测装置和方法。 相机装置(2)被布置成检测车辆驾驶员(4)的眼睛配置。 控制单元(5)将检测到的眼睛配置与预先存储的眼睛配置样本(13,14,15,16)的模型进行比较,该眼睛配置样本指示在预定视场内部或外部观看的眼睛(6)。 控制单元(5)进一步确定检测到的眼睛配置是否在比较之内的内部或外部的预定视野内,并且还被布置为指示车辆驾驶员(4)何时被确定在外部的预定场地 (6)到预定的程度。

    • A drowsiness detection device and method for a person (4), having a digital camera device (2) and a control unit (5). The digital camera device (2) includes a video processor (6). The digital camera device (2) is arranged to detect the eyes (3) of the person (4) in a series of images. The video processor (6) is arranged to detect eyelid movements in the images and convert images of the eyelid movements to an electric signal (s(t)) which is transferred to the control unit (5) The control unit (5) is arranged to fit a modeled signal (y(t)) against the electric signal (s(t)) and to determine whether the modeled signal (y(t)) constitutes an eyelid blink. The control unit (5) uses a number of modeled signals (y(t)) determined to constitute an eyelid blink to determine whether the level of alertness has fallen below a certain threshold.
