Research On The Active Safety Technology For The Urban Road Vehicle

With the social development, The traffic safety issues become more and more prominent,causing the widespread concern of the society and the government. The traditional vehiclesafety concept is gradually changing, The research of intelligent vehicle with activeanti-collision function is very important.This paper reviews the various specific calculation method of the vehicle safety distancein the active anti-collision measuring system. According to the current vehicle road trafficaccident of high-frequency, this article researchs the lateral and longitudinal collision and thesafety distance of changing lanes in the many lanes. This research has the important mean for theimpovement of the road traffic safety.This article compares the application scope of the existing vehicle ranging technology,discusses the ultrasonic detection technology, laser detection technology and millimeter wave detectiontechnolog and analyzes the error of ultrasonic ranging technology.The determination of the vehicle safety driving distance is factored by the driver’sdriving experience，driving conditions of the vehicles and the natural environment. This paperdesigns the calculation method of the vehicle safety driving. The method has the referencevalue and practical significance to the relevant studies.
