    • A CPU of a navigation device includes a clock unit, a continuous driving time measurement unit that measures continuous driving time from a traveling start time, a course stage prediction unit, and a presenting information controller. The course stage prediction unit selects based on the traveling start time, a first transition determination reference time for transition from a “first stage” to a “middle stage” from prepared data of the first transition determination reference time and a second transition determination reference time for transition from the “middle stage” to a “last stage” from prepared data of the second transition determination reference time. The course stage prediction unit then predicts a course stage by comparing the continuous driving time with the selected transition determination reference times. Depending on the predicted course stage, the presenting information controller presents information convenient for a driver in the predicted course stage.
    • 导航装置的CPU包括时钟单元,连续驱动时间测量单元,其测量从行驶开始时间开始的连续行驶时间,课程预测单元和呈现信息控制器。 课程阶段预测单元基于行驶开始时间,从第一转变判定基准时间的准备数据和第二转变判定基准时间从“第一阶段”到“中间阶段”的转变的第一转移判定基准时间 用于从第二转变确定参考时间的准备数据从“中间阶段”转换到“最后阶段”。 课程阶段预测单元然后通过将连续行驶时间与所选择的转移确定参考时间进行比较来预测课程阶段。 根据预测的课程阶段,演示信息控制器在预测课程阶段提供方便驾驶员的信息。

    • A preprocessing unit calculates a square sum SJ(tn) of jerk J, and a driving characteristic calculation unit determines whether the jerk square sum SJ(tn) is equal to or above a predetermined threshold value. The position/traveling direction determination unit determines the position and traveling direction of the vehicle. A troublesome driving place determination unit records an intersection at which the jerk square sum SJ(tn) is calculated to be equal to or above the predetermined threshold value and the traveling direction of the vehicle at that time in association with each other in a troublesome driving place database. With reference to the troublesome driving place database, the troublesome driving place determination unit then calculates the risk cost at each intersection around the vehicle for each traveling direction. It is therefore possible to perform route guidance taking the driver's personal feeling into an account.
    • 预处理单元计算加加速度J的平方和SJ(t N n N),驱动特性计算单元判定冲击平方和SJ(t N n N)是否等于 或高于预定阈值。 位置/行进方向确定单元确定车辆的位置和行进方向。 麻烦驾驶位置确定单元记录计算出冲击平方和SJ(t N)的交叉点等于或高于预定阈值以及当时的车辆行驶方向 在一个麻烦的驾驶地点数据库中相互联系。 参照麻烦的驾驶位置数据库,故障驾驶位置决定单元计算出每个行驶方向的车辆周围的各交叉路口的风险成本。 因此,可以根据驾驶员的个人感觉进行路线指导。
