Development of a Backup Collision Intervention System

摘要

This paper describes a system designed to assist drivers when backing out of a parking space.The system has the following functions that help to prevent the host vehicle from coming tooclose to objects behind it or to vehicles approaching it from the rear or either side whenreversing. Audible and visual warning advises the driver of the presence of an approachingobject. The system generates force to push back the accelerator pedal if it is being depressedby the driver. The system applies brake if it judges that braking is needed. Radar sensors andsonar sensors are fitted to the rear for detecting objects behind the vehicle. A brake actuatorand an accelerator pedal actuator for generating force to push back the pedal are provided. Aprototype test vehicle was built and driving tests were conducted by a panel of ordinarydrivers in public parking lots. The results confirmed that the system worked as designed.
