An image recognition section detects a first traffic regulation sign from a picked-up image of an area in front of a vehicle. An acquisition section uses a position of the vehicle to acquire a road link, including a second traffic regulation sign at the position of the vehicle, from a storage section. When no current first traffic regulation sign is detected on a current road link after turning-right or turning-left of the vehicle, a determination section determines a current final traffic regulation sign on the current road link, which is to be notified to a vehicle occupant, by use of a degree of adequacy of cooperation between previous first and second traffic regulation signs detected and acquired on a previous road link before the turning-right or turning-left of the vehicle, but also previous and current factors acquired on the previous and current road links.
