MAKING TRANSPORT SAFER: V2V-BASED AUTOMATED EMERGENCY BRAKING SYSTEM

Abstract. An important goal in the field of intelligent transportation systems (ITS) is to provide driving aids aimed at preventing accidents and reducing the number of traffic victims. The commonest traffic accidents in urban areas are due to sudden braking that demands a very fast response on the part of drivers. Attempts to solve this prob-lem have motivated many ITS advances including the detection of the intention of surrounding cars using lasers, ra-dars or cameras. However, this might not be enough to increase safety when there is a danger of collision. Vehicle to vehicle communications are needed to ensure that the other intentions of cars are also available. The article describes the development of a controller to perform an emergency stop via an electro-hydraulic braking system employed on dry asphalt. An original V2V communication scheme based on WiFi cards has been used for broadcasting positioning information to other vehicles. The reliability of the scheme has been theoretically analyzed to estimate its performance when the number of vehicles involved is much higher. This controller has been incorporated into the AUTOPIA pro-gram control for automatic cars. The system has been implemented in Citroën C3 Pluriel, and various tests were per-formed to evaluate its operation
