WIRELESS VEHICLE TO VEHICLE WARNING SYSTEM

To satisfy the increasing demand for automotive safety a warning system (WARN) to support drivers has been developed. The basic idea is to transmit safety-related information from one vehicle to surrounding vehicles by direct wireless communication. To ensure user-acceptance of the system different strategies have been developed in order to provide only relevant information to a specific driver. The strategies rely on a comparison of the received alert messages with the current driving situation. Simulations show a significant safety-improvement due to the system if at least 10 percent of all vehicles are equipped with the system. (A) For the covering abstract see ITRD E106371.

Wireless Inter-Vehicle Communication for Hazard Warning

Abstract Increasing automotive safety may be achieved by notifying drivers about incidents ahead. To enable drivers for proper reaction a warning system has been developed. Safety-related information is transmitted from one vehicle to surrounding vehicles by direct wireless data communication. The system evaluates some signals provided by the vehicle to detect hazardous conditions. Different strategies have been developed to decrease drivers interaction and to provide only relevant information to a specific driver. Simulations show a significant safety improvement due to the system if at least 10 to 15 percent of all vehicles are equipped with the systems.
