Title:
POSITION CORRECTING DEVICE, NAVIGATION SYSTEM, AND AUTOMATED DRIVING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/135431
Kind Code:
A1
Abstract:
This position correcting device is provided with a receiving unit (49), a position acquiring unit (51), a determining unit (53) and a position information transmitting unit (55). The receiving unit receives position information S1 of a vehicle from a navigation device which has the function of acquiring the position information S1. The position acquiring unit acquires position information S2 of the vehicle with a higher accuracy than the navigation device. The determining unit determines whether a difference between the position information S1 and the position information S2 exceeds a predetermined threshold, or determines whether a traveling road specified by the position information S1 matches a traveling road specified by the position information S2. If it is determined that the difference exceeds the threshold, or if it is determined that the specified traveling roads do not match, the position information transmitting unit transmits the position information S2 to the navigation device.
