Patent ID: 7440847

Claim:
A navigation system for guiding a moving object from a current position to a destination comprising: a setting device that sets the current position and the destination, using map information; a sensor that detects movement of the moving object; a computing device that calculates a move distance, without regard to a direction of movement, that the moving object has moved from the current position based on data outputted from the sensor, the computing device determining a position of the moving object by shifting the current position by the calculated move distance, along a designated path defined by designated path data between the current position and the destination, which designated path data have been determined by a path planning; and a display device for displaying path guidance information depending on the determined position of the moving object; wherein, said display device displays said designated path as nodes and links in a linear map arrangement, as path guidance information; and when said moving object approaches a particular intersection or corner, said display device further displays a two-dimensional partial map which indicates that particular intersection or corner by using map information, to prompt the moving object to change its orientation.
