摘要

In 2008, Raytheon Company created a partnership with Toyota Motor Engineering and Manufacturing North America, Inc. (TEMA) to develop the Cooperative Pedestrian Warning System (CPWS) vehicle safety application. This system detects pedestrians via passive sensors, maps their current and future predicted locations to an interface grid based on a GPS reference plane, and sends the location probability information to nearby vehicles. Once a likely pedestrian collision is detected, a warning is presented to both the vehicle driver and the endangered pedestrian. The CPWS system is designed with a video analytics-based front feeding Raytheon's patent-pending Pedestrian Prediction Logic (PPL) which reports to the GPS reference plane. The CPWS uses a Dedicated Short Range Communication (DSRC) based 5.9 GHz wireless infrastructure-to-vehicle (I2V) link for communication between the roadside and vehicle radios, leveraging technology from the Vehicle Infrastructure Integration (VII) initiative. CPWS was successfully demonstrated at the 2008 World Congress on ITS in New York City.
