    • A plurality of position data sets representing a plurality of points on a road ahead of a vehicle are acquired, and the degree of curvature of the road at each point is computed. On the basis of the degree of curvature, a constant curvature degree section of a curve is identified, and the degree of curvature and the end position of the constant curvature degree section are determined. In order to cause the vehicle to properly pass through the curve, curve deceleration control is executed on the basis of the actual vehicle speed, a proper vehicle speed determined from the degree of curvature, and the end position of the constant curvature degree section. That is, the curve deceleration control is performed on the basis of the start point of a section of a curve having the maximum degree of curvature and the constant degree of curvature of that section.
    • 获取表示车辆前方道路上的多个点的多个位置数据组,并计算出各点的道路的曲率。 基于曲率,确定曲率的恒定曲率部分,并且确定恒定曲率部分的曲率和终点位置。 为了使车辆正确地通过曲线,基于实际车速,从曲率度确定的适当车速和恒定曲率度部分的终点位置来执行曲线减速控制。 也就是说,曲线减速控制是基于具有该部分的最大曲率半径和恒定曲率的曲线的一部分的起点进行的。

    • An X-ray diagnostic system has a display unit, a selection unit, a calculation unit and an imaging execution unit. The display unit displays images of a plurality of frames collected by a predetermined frame rate about an object. The selection unit selects an image of a particular frame from the images of the frames displayed on the display unit. The calculation unit calculates a delay time to the particular frame selected by the selection unit based on the frame rate. The imaging execution unit executes an imaging based on the delay time calculated by the calculation unit.
