Multifunctional intelligent anti-collision device of automobile

Abstract

The invention discloses a multifunctional intelligent anti-collision device of an automobile. The device comprises an air bag, anti-collision detecting units and an anti-collision controller. The anti-collision detecting unit comprises a front camera, a head ultrasonic distance measurement sensor, a rear camera, a tail ultrasonic distance measurement sensor, an infrared human detection sensor, an automobile speed sensor and an acceleration sensor. The anti-collision controller comprises a DSP digital signal processor, a voltage conversion circuit module, a touch liquid crystal display, a Flash memory, a USB communication circuit, a GPRS wireless communication module, a clock circuit module, a signal conditioning circuit, a voice play circuit and a relay. The multifunctional intelligent anti-collision device of the automobile is simple in structure, reasonable in design, convenient to use and operate, capable of avoiding accidents such as reversing collision, collision with an obstacle ahead due to acceleration, collision with a rear obstacle due to emergency braking, secondary collision after a car accident and the like, complete in functions, high in working stability and reliability, high in practicality and convenient to popularize and use.

Description

technical field [0001] The invention belongs to the technical field of transportation safety, and in particular relates to a multi-functional smart car anti-collision device. Background technique [0002] With the rapid development of my country's transportation industry and the sharp increase in car ownership, road traffic accidents have become a hot topic of global concern. The rapid development of expressways has provided good driving conditions for vehicle operations and greatly improved road traffic conditions. However, the traffic accidents that follow have also increased significantly, causing serious losses to the lives and properties of the country and the people. In the prior art, there are the following situations in automobile collisions: (1) the driver's fault is the main factor that causes road traffic accidents, no matter from the total amount of accidents or the number of casualties, they respectively reach more than 90% of the total amount. Among the facto...

(2) The secondary collision accident is more serious than the primary accident, and has a greater impact, directly threatening the life safety of the primary accident survivors, accident rescuers and on-site survey personnel; therefore, some devices to prevent secondary collisions have appeared on the market

However, most of the current markets are actively preventing secondary collisions, and there are few devices for passive prevention.

However, for different drivers, their reaction speed and judgment ability are different, and the device for actively preventing secondary collisions does not work very well in many cases.

(3) When the car is starting, turning around or reversing, the driver's field of vision is quite limited because the low-speed vehicle is very close to other vehicles or obstacles

The driver needs to observe the situation behind the car with the help of the rearview mirror. However, the viewing angle of the rearview mirror is limited, and it is often impossible to completely see all the situations behind the car. Although some cars are equipped with brake adjustment systems and rear Mirror angle adjustment device, but in the process of use, the driver will be greatly distracted by adjusting the angle device, and it is very easy to collide
