APPLICATION OF LASER RADAR TO REAR-END COLLISION WARNING SYSTEM

A rear-end collision warning system for heavy-duty trucks using laser radar has been developed by Nissan, Nissan Diesel and Kanto Seiki. The range to a target is calculated on the basing of the elapsed time between transmission of a laser pulse and reception of reflected light. The design of this co-operative laser radar system is based on the assumption that targets are reflex reflectors. Two key technologies of this system are also described. One is the calculation method for obtaining a stable range rate using normal distributed range data. The other is the warning algorithm in which human factors are taken into consideration.
