RADAR-BASED GUIDANCE AND WIRELESS CONTROL FOR AUTOMATED VEHICLE PLATOONING AND LANE KEEPING ON AN AUTOMATED HIGHWAY SYSTEM

摘要

A computerized system onboard a vehicle for automatic radar-based vehicle guidance includes a front-looking radar sensing module. The front-looking radar sensing module comprises a pair of radar sensors. The pair of radar sensors are placed at front of vehicle. The pair of radar sensors emits radar waves at a specified radar frequency and senses reflected radar waves. The radar waves are reflected by a set of radar reflectors placed at the side of a roadway at a distance ahead of the vehicle on the roadway. The front-looking radar sensing module obtains a reflected-radar information from the pair of radar sensors and determines the distance between the vehicle and the radar reflectors ahead of the vehicle at a specified time.
