Emergency reporting device

摘要

An emergency reporting device is configured to reduce the load of communication circuits of base stations when sending emergency signals. The emergency reporting device is configured to track the time in the travel time recording section from when a vehicle last exited a communication area of a base station until it detects a peripheral vehicle or track the time in the same manner for a peripheral vehicle as well. When the vehicle encounters a peripheral vehicle after receiving an emergency signal from an emergency vehicle, an exchange of travel information occurs between the two vehicles. The emergency reporting device determines whether or not to send the emergency signal held by the vehicle to the peripheral vehicle based on the travel information that was exchanged when the vehicles encountered each other.
