The Design And Research On Control System Of The Automobile Floating And Recovering Automatically System In Water

Now, the safety of the automobile is increasingly paid attention to us. The safety of the automobile is divided into the active safety and passive safety, the passive safety is that the automobile protect the passenger's ability when the accidents occur. The passive safety of automobile is an important part of the automobile safety, now there take place many accidents of falling into water, result in huge great damage to people. Therefore we should provide some safety measure when the automobile fall into water.For long time, people gradually installed various safety measures to automobile, But because of various reasons,-effectively safety measure had been not provide after the automobile fall into water. The design of The Automobile F, loating and Recovering Automatically System in Water really according to this consideration, it can make automobile float to the surface of the water and the passenger can flee safely. So it can protect the safety of people.The thesis starts by introducing the present passive safety measure of the automobile, educing the passive safety measure of the automobile that have not—The Automobile Floating and Recovering Automatically System in Water. The thesis mainly introduce the principle and realizer procession of The Automobile Floating and Recovering Automatically System in Water, demonstrate the possibility of this system, design the control system of The Automobile Floating and Recovering Automatically System in Water. When the system collect definite signal of pressure and speed, opening the drive machine, making use of the air occurrence machine charge to the air bag, and opening plastics foam controller, making use of the buoyancy of the air bag and plastics foam makes the automobile float on the surface of the water, or make the automobile Recover automatically.The thesis designs the whole scheme and control system of The Automobile Floating and Recovering Automatically System in Water. Analyse various circumstance of automobile falling into water, elaborate to various part of control system. And Combine the effective demand of the automobile, design each module and concrete installation position on the automobile, which emphasize on the character of air bag and charge process. And elaborate some relations among this system and storage battery, the ABS system and other systems in automobile. In order to realize the schedular function, thesis design the signal procession system ,electronic control system, drive system, ignition system, automatic display system, electrical source system, etc. hardware system, and the electronics control system is the whole core subsystem of whole system. And in virtue of keil C51 software program the control software with C language, thus it can realize the automatic control of the whole system. After designing the hardware and software, the thesis do some primary test imitating the actual condition that the automobile fall into water, and get some data and experience, demonstrate the possibility of the system form practice.The design of The Automobile Floating and Recovering Automatically System in Water, develop new realm for the passive safety design of the automobile, realize the break that have no the effectively safety measure after the automobile fall into water, and it indicates the development direction for safety design about this aspect.
