Abstract
An inter-vehicle communication and driving assistance device performs wireless communication with other vehicles, and includes an inter-vehicle communication unit including a reception level detection unit, a position information reception unit, and an arithmetic processing unit. The arithmetic processing unit calculates inter-vehicle distances to other vehicles using latitude and longitude information of the other vehicles and the own vehicle, receives a position error radius, and acquires a reception level from the other vehicles. When a difference between the inter-vehicle distances is smaller than position error radius, a vehicle with a larger reception level is determined as a vehicle closer to the own vehicle. When the difference between the inter-vehicle distances is larger than the position error radius, a vehicle with a smaller inter-vehicle distance is determined as a vehicle closer to the own vehicle, and a distance to a leading vehicle is calculated.
