AUTOMOTIVE DRIVE ASSIST SYSTEM WITH SENSOR FUSION OF RADAR AND CAMERA AND PROBABILITY ESTIMATION OF OBJECT EXISTENCE FOR VARYING A THRESHOLD IN THE RADAR

摘要

An ACC system (1) includes: a millimeter radar (10); a stereo camera (11); a preceding vehicle recognition ECU (20) that determines object type information indicating the detection status of these components; and a cruise control ECU (30) that controls a brake actuator (40) and an electronically-controlled throttle valves (41) based on object parameters and the object type information. With regard to the object detected by the millimeter wave radar (10) with the intensity of a received radio wave equal to or higher than a lower threshold value that is lower than higher threshold value, the object that is detected also by the stereo camera (11), or the object that was detected by the millimeter wave radar (10) with the intensity of a received radio wave equal to or higher than a higher threshold value is treated as the preceding vehicle candidate.
