    • In construction machinery, control is conducted to keep a work machine to operate at a constant speed regardless of the operation thereof. Different engine output lines T0-T3 and pump torque lines M1-M4 are defined for different operation types. All the matching points of the engine output lines T0-T3 and pump torque lines M1-M4 designate a constant engine speed N1. One engine output line and one pump torque line are selected according to the operation type presently selected. An output horsepower of the engine is controlled on an equal horsepower line corresponding to a sum of a horsepower for an auxiliary machine and a horsepower at a matching point of the selected lines. The pump torque for the work machine is controlled on the selected pump torque line. The engine operates at a constant speed N1 even when the operation type varies or the horsepower for the auxiliary machine changes.
    • 在施工机械中,进行控制以使作业机器以恒定的速度运行,而不管其操作如何。 针对不同的操作类型定义不同的发动机输出线T 0 -T 3和泵扭矩线M 1 -M 4。 发动机输出线T 0 -T 3和泵扭矩线M 1 -M 4的所有匹配点表示恒定的发动机转速N 1。根据当前选择的操作类型选择一个发动机输出线和一个泵扭矩线。 发动机的输出功率被控制在对应于辅助机器的马力与选定线路的匹配点的马力之和的等马力线路上。 工作机械的泵扭矩由选定的泵扭矩线控制。 即使操作类型变化或辅助机器的马力发生变化,发动机也以恒定速度N 1运行。

    • When a moving body (e.g., a car) is entering a roundabout, a navigation machine extracts link data of the roundabout from road map data. The navigation machine detects a route entering the roundabout (i.e., a route the moving body is currently taking), a center of the roundabout, and an exiting route based on the link data to determine an angle of the exiting route with respect to the entering route. A direction mark having the exiting route angle is prepared as a heading direction guidance image. The navigation machine can show an appropriate route (direction) at the roundabout without increasing the amount of stored image data.
    • 当移动体(例如,汽车)进入回旋处时,导航机从路线图数据中提取回旋处的连接数据。 导航机器检测进入环形交叉路口的路线(即,移动体当前正在进行的路线),回旋处的中心,以及基于链接数据的离开路线,以确定出口路线相对于进入的角度 路线。 具有出口路线角度的方向标记被准备为航向方向引导图像。 导航机可以在回旋处显示适当的路线(方向),而不增加存储的图像数据量。
