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. |
