2、owing concern, the security points to the initiative and passive safety and security is passive safety accident, the protection of the crew. the passive security is an important part of the security, and now it happened many of the car accident, falling into the peoples lives and property has caused

3、 great losses, and urgently needed in this respect, and provide appropriate security measures to ensure that the peoples lives and property security. Long, people came to the car fitted with all kinds of security measures, but owing to various reasons have been unable to provide in the fall of the s

4、ecurity measures after the drowning escape system design, it is therefore considered that the car fell through the car after the safety device, the crew can escape the safety and to ensure that the peoples security. The papers on the bus has a passive security devices, led to the new car is not the

5、passive security device of the car for a fall. the paper mainly on the ground safety system and implement the principle of the process, the feasibility of this system, designed to the ground safety systems of control system. The sensor system were to sign, monolithic integrated circuits, will the si

6、gnal in the glass drive, quickly open the glass. Paper work out the car had a device for the overall plan and control systems, for the drowning of the situation was analysed and control systems of various components of the united states and the actual needs and developed its various components, and

7、in the interior of the installation, emphasizing to monolithic integrated circuits to control was analysed. In order to achieve the intended function, the preliminary design of the system of signals to penetrate the systems and electronic control system power supply system, the system, including ele

8、ctric control system is the core of the system, subsystem, and the aid of a system of control software, the whole system of automatic. System design in hardware and software completed, the paper and a car into thewaters of the actual situation in a preliminary test and made some data and experience

9、from in practice, and argues for the system of feasibility. The ground safety device design, safety design for the passive opened up new areas and achieved in the car had no valid security measures after the breakthrough in this respect, safety design pointed out the development direction to our car

13、汽车落水逃生系统概述汽车落水逃生系统是汽车安全系统的一个组成部分，由于现在对汽车安全性能要求的越来越高，需要越来越多的安全措施，而现在也发生了许多汽车落水事故给人们的生命财产造成了巨大的损失。本系统的研发正是针对这种情况，通过此措施来提高汽车的被动安全性能。系统的基本构想是：在汽车落水后，传感器检测水位或水压信号，通过电路进行处理后，迅速启动备用电源和密封式车窗升降器，降下车窗玻璃 ，从而得到安全逃生的目的。其工作原理为：当汽车落水后，通过安装在汽车内部、低部位的水位或水压传感器，将所感应到的水压或水位信号传入控制电路，控制电路接收并处理传感器的信号，一旦压力达到设定的触发电压时，控制电路发出信号使得整个系统回路导通，通过控制电路启动应急电源和电机，使得汽车后部车窗快速落下，由于传感器安装部位较低，以及汽车自身具有一定的浮力，当系统启动时，汽车外部水位没有将车后部的车窗全部淹没，车窗快速降下后，人可以快速从车内逃出。12 汽车落水逃生系统研究现
