Vehicle distance control system based on communication among vehicles and control method thereof

Abstract

The invention discloses a vehicle distance control system based on communication among vehicles and a control method thereof. According to one aspect of the invention, the vehicle distance control system based on communication among vehicles comprises a relative distance and speed input part which receives a relative distance and a relative speed between a front vehicle and the vehicle; a communication part which receives pavement information from an identified front vehicle; a constant changing part which compares the received pavement information with the pavement information received at a previous time point and changes a vehicle distance constant when the pavement information changes; a target vehicle distance calculation part which calculates a target vehicle distance between an identified front vehicle and the vehicle according to the changed vehicle distance constant; and a target acceleration calculation part which utilizes the received pavement information to calculate a target acceleration of the vehicle. According to the invention, a safe distance is ensured according to pavement assistance.

Description

technical field [0001] The present invention relates to a vehicle-to-vehicle communication-based vehicle distance control system and a control method thereof, in particular to calculating the road-based target vehicle distance of a vehicle traveling behind by using road surface information received from a vehicle traveling ahead through vehicle-to-vehicle (V2V) communication A vehicle-to-vehicle distance control system based on inter-vehicle communication and a target acceleration and a control method thereof. Background technique [0002] According to statistical results, with the rapid popularization of vehicles, the growth rate of vehicles is much faster than the expansion speed of road network. [0003] Therefore, with the increasing risk of collisions between vehicles on the road, in combination with consumer demand for safer and smarter cars and the development trend of the car-related industry, various smart safety systems have been developed and put into use .

AI Technical Summary

Problems solved by technology

[0021] The inter-vehicle distance control system installed on existing vehicles fixes the maximum deceleration to 9.8m without fully considering the friction coefficient between the tire conditions and the road surface when calculating the minimum safety distance for the driver based on the maximum deceleration while driving. / s 2 , so the optimal safe distance cannot be ensured

[0022] Therefore, its disadvantage is that it is impossible to avoid a collision between the vehicle in front and the vehicle in case of an emergency
