PROBLEM TO BE SOLVED: To avoid a condition where an occupant feels troublesome or disagreeable by providing the sound guide including the simplified content when a vehicle travels on a route where the vehicle traveled in the past relatively frequently, i.e., when the route is known and sufficiently familiar to the occupant. SOLUTION: A control unit 60 to fetch the passing frequency data DCO from a passing frequency counter part 62 compares the passing frequency to be indicated by the passing frequency data DCO with a prescribed frequencyαA, for example, 5 times, and the prescribed frequencyαB, for example, 10. Whether or not the passing frequency indicated by the passing frequency data DCO is 5 or less, and when the passing frequency exceeds 5, whether or not the passing frequency is not less than 6 and not more than 10, is judged. When it is not more than 5, the control unit 60 forms the command signal CG to indicate the regular guide. When it is not less than 6 and not more than 10, the command signal CG to indicate the simple guide is formed, and when it exceeds 10, the command signal CG to indicate the guide stop is formed. |
