PROBLEM TO BE SOLVED: To correctly predict a destination and a required time in accordance with driving hysteresis of a driver. SOLUTION: A car-mounted information device detects driving starting and completion by driving starting and completion detection means 6, 10, and accumulates and stores driving starting and completing points, date, and traveling distance as driving hysteresis information in a driving hysteresis storing means 11. In starting driving, a frequency determining means 13 searches the operation hysteresis information in the driving hysteresis storing means 11 based on searching conditions of a current time and a current position detected by a current place detection means 1, and forms required time frequency distribution data to destination frequency distribution data and required time frequency distribution data to a destination of the highest frequency. A destination is predicted by a destination predicting means 14 based on the destination frequency distribution data, a required time to the destination is predicted by a required time predicting means 15 based on the required time frequency distribution data, sound is outputted by a sound outputting means 18, and the destination frequency distribution data and the required time frequency distribution data are displayed in graphs by a display means 5. |
