    • PURPOSE: A vehicle position value generating system and method are provided to create a vehicle position value at an appropriate quality and an affordable price in region where a global positioning system(GPS) signal is not receivable. CONSTITUTION: A vehicle position value generating system(100) comprises a rotation detecting device(110), a grade sensor(120), a satellite navigation device(130), and a position value calculating device(140). The rotation detecting device detects rotation quantity of left and right sides of two front wheels or two rear wheels, respectively, according to the operation of a vehicle. The grade sensor detects a grade of the vehicle. The satellite navigation device obtains a first position value of the vehicle by using three or more artificial satellites. The position value calculating device calculates the amount of movement of the vehicle in a three-dimensional space by using the rotation quantity and the grade of the vehicle when the satellite navigation device is unable to function appropriately. The position value calculating device creates a second position value of the vehicle by using the first position value and the calculated amount of movement.
    • 目的:提供一种车辆位置值生成系统和方法,以在不能接收全球定位系统(GPS)信号的区域中以适当的质量和可承受的价格创建车辆位置值。 构成:车辆位置值生成系统(100)包括旋转检测装置(110),等级传感器(120),卫星导航装置(130)和位置值计算装置(140)。 旋转检测装置根据车辆的操作分别检测两个前轮或两个后轮的左右两侧的旋转量。 等级传感器检测车辆的等级。 卫星导航装置通过使用三个以上的人造卫星来取得车辆的第一位置值。 位置值计算装置在卫星导航装置不能正常工作时,通过使用车辆的旋转量和坡度来计算三维空间中的车辆的移动量。 位置值计算装置通过使用第一位置值和计算出的移动量来创建车辆的第二位置值。
