A vicinity environment estimation device includes neighborhood monitoring sensors that detect another vehicle, a car navigation system that acquires information about an untravelable region where a vehicle cannot travel, a vehicle-to-vehicle communication instrument that acquires information about detectable regions and results of detection of neighborhood monitoring sensors mounted in the another vehicle by wireless communication, and an ECU that estimates presence of a vehicle in the neighborhood of a host vehicle. When a blind closed region surrounded by detectable regions of the neighborhood monitoring sensors mounted in the another vehicle received by the host vehicle, detectable regions of the neighborhood monitoring sensors mounted in the host vehicle, and the untravelable region is formed, the ECU estimates the number of vehicles in the blind closed region which is not directly detectable by the neighborhood monitoring sensors, by continuously managing the entry/exist of vehicles to/from the blind closed region.
A vicinity environment estimation device that detects obstacles traveling in a vicinity of a host vehicle and notifies a user, the vicinity environment estimation device comprising:
A control method for a vicinity environment estimation device that includes an obstacle detection portion that detects an obstacle present in a vicinity of a host vehicle, a no-entry region acquisition portion that acquires an untravelable region where it is impossible for a vehicle to travel, and a vehicle-to-vehicle communication instrument that receives from another vehicle a result of detection of obstacle detection portions, which detect an obstacle present in a vicinity of the other vehicle, mounted in the other vehicle and detectable regions of the obstacle detection portions mounted in the other vehicle, the method comprising:
