PROBLEM TO BE SOLVED: To perform highly accurate search. SOLUTION: This system has a search mode setting processing means for setting a search mode for avoiding irradiation of sunlight onto a vehicle seat, a passing time estimation processing means for estimating a passing time of a prescribed spot on a road from a starting place to a destination, a search cost calculation processing means for calculating search cost based on an irradiation state of the sunlight on the seat side set in the search mode when traveling along the road at an estimated passing time relative to the road, a route determination processing means for searching for a route based on the calculated search cost. Since the search cost is calculated based on the irradiation state of the sunlight on the seat side set in the search mode, highly accurate search can be performed based on the search mode.
