Embodiment Construction

[0053] Such as figure 1 As shown, the radar is used to detect the distance and angle of the obstacle in front of the vehicle from the vehicle, and the speed of the obstacle relative to the vehicle; the steering wheel angle sensor is used to collect the rotation angle of the steering wheel; the vehicle speed sensor is used to measure the speed of the vehicle. Real-time driving speed; the turn signal sensor is used to collect the switch information of the turn signal; the camera is used to collect the road surface image information in front of the car in real time; the positioning speed sensor is used to locate the car and measure the speed of the car in real time; The central processing unit is used to receive the information sent by the radar and judge the danger level of the vehicle caused by the obstacles in front, judge the driving direction of the car according to the signal sent by the steering wheel angle sensor, and judge the driving direction of the car according to the...

Abstract

The invention relates to a high-reliability and low-false alarm rate highway automobile anti-collision system and method. The highway automobile anti-collision system comprises a central processing unit, radar, a steering wheel angle sensor, a vehicle speed sensor, a steering lamp sensor, a camera, a location speed measurement sensor and an output unit, wherein the radar communicates with the central processing unit. The technical problem that the false alarm rate of a traditional radar automobile intelligent anti-collision system is high is solved by the highway automobile anti-collision system. According to the highway automobile anti-collision system, by utilizing the multi-sensor fusion technique, the advantages of all the sensors are fully exploited; the integrated information of people, vehicles and roads is provided, and therefore, false alarms caused by traffic signs, temporary passage vehicles, roadside buildings, curves, overtaking and platform bridges are reduced, unreal obstacles are eliminated, and the false alarm rate under the complicated environment is reduced.

Description

technical field [0001] The invention belongs to the field of traffic safety, and in particular relates to a high-reliability and low-false-alarm-rate highway vehicle collision avoidance system and method. Background technique [0002] Traffic accidents have become "the world's number one killer" in peacetime. According to the data released by the World Health Organization, 1.2 million people die in road traffic accidents around the world every year, and 50 million people are injured at the same time, with an average death of one person every half minute; [0003] my country is one of the countries with the largest traffic accident casualties in the world. In the past ten years, the total number of traffic accident injuries and deaths in my country has been more than 500,000 people every year. On average, one person dies in a car accident every five minutes. [0004] Based on the above situation, automobile anti-collision has become a hot research point, and the current aut...
