Embodiment 1

[0020] In order to overcome the problems of heavy burden on the driver, high judgment errors and unsafe traffic in the existing system, the present invention provides an active safety system for preventing rear-end collisions of automobiles. figure 1 , figure 2 , image 3 The automobile anti-rear collision active safety system shown in this system adopts the combination of radar distance measurement and sound and light alarm system. This alarm method combined with sound and light produces double visual and auditory stimulation to the driver, causing driving staff's attention. The detection performance of radar ranging is not affected by the shape and color of objects, and the detection accuracy is less affected by weather and environment. The ranging distance is long and the accuracy is high, which is more suitable for the requirements of automobile anti-collision active safety systems.

[0021] The automobile anti-rear collision active safety system includes a distance mea...

Embodiment 2

[0026] Based on the basis of Embodiment 1, the ranging module described in this embodiment is a radar ranging system, and the radar ranging system is composed of an electromagnetic wave transmitting module, an electromagnetic wave receiving module and an information processing module, and the electromagnetic wave transmitting module and the electromagnetic wave receiving module Signal connection, the signal connection between the electromagnetic wave receiving module and the information processing module.

[0027] The electromagnetic wave transmitting module is installed on the front end of the vehicle to send microwave signals to the front of the vehicle; the electromagnetic wave receiving module is installed on the front end of the vehicle to receive the reflected signal reflected by the vehicle in front of the transmitted signal; the information processing module is responsible for signal modulation radio frequency Signal transmission and demodulation of received signals.

Embodiment 3

[0033] Based on the above two embodiments, in this embodiment, the control module is a fuzzy control system, and the fuzzy control system is composed of a fuzzy controller, a controlled object and a feedback quantity, and the feedback quantity is the input of the fuzzy controller. The controller first feeds back the quantity to fuzzify it, then activates the corresponding fuzzy control rules, and uses the fuzzy reasoning method to obtain a new fuzzy quantity, then clears the fuzzy quantity, and finally obtains a precise value as the fuzzy value after defuzzification The output of the controller to control the controlled object.

[0034] The working process of the fuzzy control system is that the radar ranging system obtains the output of the controlled object, compares it with the given value, and obtains the deviation between the two as the input of the fuzzy controller. The fuzzy controller first fuzzifies it into a fuzzy quantity, then finds the fuzzy decision-making logic ...

Abstract

The invention provides an automobile rear-end collision prevention active safety system. The automobile rear-end collision prevention active safety system comprises a distance measuring module mountedon an automobile head, a sound and light alarm installed on an automobile instrument board and a control module installed under the instrument board. The control module is separately connected with the sound and light alarm and the distance measuring module, and the control module receives information detected by the distance measuring module to control the sound and light alarm to issue an alarm. The alarm combination of sound and light creates visual and audible double stimulus to a driver to attract attention of the driver. The detection performance of radar distance measuring is not affected by the shape and color of an object, the detection accuracy is less affected by weather and environments, the distance measuring distance is far and the precision is high, and the radar distance measuring can better meet the requirements of the automobile rear-end collision prevention active safety system.

Description

technical field [0001] The invention is actually an active safety system for preventing rear-end collisions of automobiles. Background technique [0002] Cars bring convenience to people, but the problems that follow are also obvious. With the increase of vehicles, traffic accidents become more and more frequent, resulting in an astonishing number of property losses and casualties. Traffic accidents have become the number one hazard in the world, and China is one of the countries with the largest number of traffic deaths in the world. Since the end of the 1980s, the number of annual traffic accident deaths in China has exceeded 50,000 for the first time, and the number of traffic accidents in mainland China has exceeded 500,000 each year, and the number of deaths due to traffic accidents has exceeded 100,000, ranking first in the world for more than ten consecutive years. . In recent years, the official statistics of the national road traffic accident deaths in China: 106,...
