Wireless safety personnel radio device for collision avoidance system of autonomous vehicles

Military, commercial and agricultural autonomous/non-autonomous vehicles are designed to operate in the vicinity of people. The wireless personal safety radio device (WPSRD) described in this paper is worn by personnel and installed on the autonomous vehicle. It can initiate various actions in response to the information about the location or moving direction of personnel or vehicles. Such actions include shutting the vehicle down or warning personnel in the field via visual and audio alarm signals from the WPSRD. When an individual perceives danger to persons or property, the stop button on the WPSRD device may be pressed, issuing an immediate command to slow/stop the vehicle. The relative distance is estimated from the relative amplitude strength from the priori known unit locations.
