    • A system and method are provided for detecting one or both eyes of the driver of a vehicle. The system includes a video imaging camera oriented to generate images of the driver's face. The system also includes a video processor for processing the images generated with the video imaging camera. Filters are applied to each of potential eye candidates to determine which candidates represent an eye, weighted values are assigned to the filtered eye candidates, and an eye is detected based on the weighting of each eye candidate. According to one aspect, different size patches of potential eye candidates are processed and compared to models.
    • 提供了用于检测车辆驾驶员的一只眼睛或两只眼睛的系统和方法。 该系统包括面向驾驶员脸部图像的摄像机。 该系统还包括用于处理由视频成像相机产生的图像的视频处理器。 将滤波器应用于每个潜在的候选眼睛以确定哪些候选者表示眼睛,将加权值分配给滤波的眼睛候选,并且基于每个眼睛候选者的加权来检测眼睛。 根据一个方面,处理潜在眼睛候选者的不同尺寸的斑块并与模型进行比较。

    • A steering control system is provided for a vehicle having a steering wheel, steerable wheels, and a hydraulic steering actuator for controlling a steering angle of the steerable wheels in response to a hydraulic control signal. The steering control system includes a hydro-mechanical valve coupled to the steering wheel and generating a first hydraulic signal as a function of steering wheel position, an electro-hydraulic valve generating a second hydraulic signal as a function of an electronic control signal, an electronic control unit generating the electronic control signal, and a hydraulic combining unit which combines the first and second hydraulic signals supplies the hydraulic control signal to the hydraulic steering actuator. The steering control system also includes a steering wheel angle sensor, a yaw rate sensor, and a steered wheel angle sensor. The control unit generates an electronic control signal as a function of the sensor signals.
    • 提供一种用于具有方向盘,可转向轮和液压转向致动器的车辆的转向控制系统,用于响应于液压控制信号来控制转向轮的转向角。 转向控制系统包括联接到方向盘并且产生作为方向盘位置的函数的第一液压信号的液压机械阀,产生作为电子控制信号的函数的第二液压信号的电动液压阀,电子 产生电子控制信号的控制单元和组合第一和第二液压信号的液压组合单元将液压控制信号提供给液压转向致动器。 转向控制系统还包括方向盘角度传感器,偏航率传感器和转向轮角度传感器。 控制单元产生作为传感器信号的函数的电子控制信号。
