Abstract
An inter-vehicle distance measuring apparatus is composed of an inter-vehicle data measuring and transmitting unit for measuring and transmitting inter-vehicle distance data related to the distance between a vehicle in front and a host vehicle, a communications unit installed by a road for receiving the inter-vehicle distance data transmitted from the inter-vehicle data measuring and transmitting unit, an inter-vehicle distance measuring unit for measuring the distance between the vehicle in front and the host vehicle, a correction amount determining unit for calculating a correction amount for correcting the distance between the vehicle in front and the host vehicle measured by the measuring unit based on the inter-vehicle distance data received by the communications unit, and a correcting unit for correcting the distance between the vehicle in front and the host vehicle measured by the inter-vehicle distance measuring unit based on the correction amount.
