[Solution] A position positioning device according to an embodiment is a position positioning device for positioning the position of a vehicle, and is provided with a first positioning unit, a second positioning unit, and a determination unit. The first positioning unit receives a positioning signal from a satellite and positions a first position of a vehicle. The second positioning unit positions a second position of the vehicle on the basis of the output of the independent positioning sensor. The determination unit sets the second position as the position of the vehicle in at least one of a case where the first position is within a range based on a predetermined position and a case where a change in the direction of travel of the vehicle is a predetermined amount.

    [解决手段]根据实施方式的位置定位装置是对车辆的位置进行定位的位置定位装置,具备第一定位部、第二定位部和判别部。第一定位部接收来自卫星的定位用信号,对车辆的第一位置进行定位。第二定位部基于独立定位用传感器的输出,对车辆的第二位置进行定位。在第一位置处于基于规定的位置的范围内的情况以及车辆的行进方向的变化为规定量的情况中的至少一方的情况下,判别部将第二位置设为上述车辆的位置。
