Automatic control system of highway automobile for avoiding rear-end collision

Abstract

The present invention provides an automatic control system of highway automobile for avoiding rear-end collision. The system comprises detection devices and a central processing unit. The system is characterized in that: the system further comprises reduction gears. The quantity of the reduction gears is the same as the quantity of the detection devices, the reduction gears are distributed on a highway each to each, the detection devices are configured to obtain vehicle speeds, the central processing unit communicates with the detection devices and the reduction gears, and it is determined whether vehicles have rear-end collision risks or not according to the vehicle speed values obtained by the detection devices; and if the vehicles have rear-end collision risks, the working of the reduction gears is controlled. In the invention, the reduction gears are arranged to perform active intervention of the vehicles which generate rear-end collision risks to reduce the relative speeds, and therefore, the probability of occurrence of rear-end collision can be effectively reduced.

Description

technical field [0001] The invention relates to the field of traffic safety, in particular to an automatic control system for automobile rear-end collision prevention on expressways. Background technique [0002] Rear-end collision is the most common form of road traffic accidents. According to the statistics of China's traffic management department, rear-end collision accidents account for about 30% of the total number of road traffic accidents, and hundreds of millions of casualties and property losses are caused by rear-end collisions every year. The main reasons for rear-end collision accidents are: the braking distance of the vehicle is longer due to high vehicle speed, the driver's awareness is low, or the driver's reaction speed is slowed down due to fatigue driving. At present, in order to prevent rear-end collisions, display screen reminders or sound The reminder mode, and the reminder object is for all passing vehicles, and there is no active and targeted preventio...
