PROBLEM TO BE SOLVED: To provide an on-vehicle navigation system which can automatically record vibrating spot information corresponding to each spot on a map on a vibrating spot recording means by measuring the position where the vibration of a road surface is detected and recording the vibration information and position information by correlating the information with map information. SOLUTION: An on-vehicle navigation system is provided with a vibration sensing means 103 which detects vibrations of road surfaces and acceleration changes by impacts, etc., from road surfaces, an its-own-vehicle position measuring means 102 which measures the position of its own vehicle by acquiring the positioning information of the GPS and various kinds of information for correcting the positioning error of the GPS, and a vibrating spot recording means 107 which records the vibration information and the position information on a spot from which the vibration information is acquired by correlating the information with map information. Therefore, the navigation system can record the vibrating spot information corresponding to each spot on a map on the recording means 107 without requiring any input from a user. |
