    • A vehicle occupant sensing system includes a plurality of image pickup devices arranged to capture a three-dimensional image in a region including at least a cover part of the front airbag system and an upper part of the front passenger seat, and a signal processing unit for processing image signals taken by the image pickup devices to determine a three-dimensional position of the captured image. The signal processing unit is configured to determine a three-dimensional position of a part of the captured image pertaining to the cover part and includes a storage section which stores in advance a reference three-dimensional position corresponding to an external configuration of the cover part, and a comparing section which compares the three-dimensional position of the image part pertaining to the cover part with the reference three-dimensional position to determine if there is an object placed on the cover part.
    • 车辆乘员感测系统包括多个图像拾取装置,其被布置成在至少包括前气囊系统的盖部分和前排乘客座椅的上部的区域中捕获三维图像;以及信号处理单元, 处理由图像拾取装置拍摄的图像信号,以确定拍摄图像的三维位置。 信号处理单元被配置为确定与盖部件相关的捕获图像的一部分的三维位置,并且包括:预先存储与盖部的外部构造对应的基准三维位置的存储部, 以及比较部分,其将与盖部分相关的图像部分的三维位置与参考三维位置进行比较,以确定是否存在放置在盖部上的物体。

    • The invention provides a railway car with superior riding quality by improving the flexural rigidity of the car body structure while suppressing increase of body structure mass. A reinforcing plate 7 is attached to a roof construction 1 on the side facing an inner side of the car body at a longitudinal center portion of a railway car body structure 10 composed of a roof construction 1, a side construction 2, an underframe 3 and an end construction 4. The range in which the reinforcing plate 7 is adhered in the longitudinal direction of the railway car body structure 10 is between two body bolsters 6, and the range in which the plate 7 is adhered in the horizontal direction of the roof construction 1 is approximately half the length of the roof construction 1 in the horizontal direction. The thickness of the reinforcing plate 7 is increased gradually as the height of the roof construction 1 in the vertical direction increases. According to this arrangement, the deformation of the roof construction 1 at the longitudinal center portion of the railway car body structure 10, which is excessive without the present arrangement, is suppressed, and the flexural rigidity of the railway car body structure 10 is effectively improved. In other words, the bending vibration of the railway car body in the vertical direction can be suppressed, and a superior riding quality is provided.
    • 本发明通过提高车身结构的抗弯刚度,同时抑制身体结构质量的增加,提供了具有优越骑行质量的铁路车辆。 在由车顶结构1,侧构造2,底架3构成的铁路车身结构体10的纵向中心部分处,在车身结构1的面向轿厢内侧的一侧的车顶结构1上安装有加强板7, 末端施工4。 加强板7沿着铁路车身结构体10的长度方向粘接的范围是在两个主体6之间,并且板7沿屋顶结构1的水平方向粘附的范围大约为一半 屋顶结构1的水平方向的长度。 随着屋顶结构1的垂直方向的高度增加,加强板7的厚度逐渐增加。 根据该结构,能够抑制在本车辆结构体10的纵向中央部处的屋顶结构体1的变形,而不会有现有的结构,因此能够有效地提高铁路车身结构体10的弯曲刚度 。 换句话说,可以抑制铁路车体在垂直方向上的弯曲振动,并提供优越的骑行质量。
