Vehicle Intelligent Safety Driving Control System Based On STM32

The popularity of cars to the people at the unprecedented convenience of transportation while its deficiencies are gradually exposed: increasingly congested traffic routes, increased traffic safety risks. Countries and people are eager to improve the situation. And a variety of MCU as the core of intelligent control technology, sensor technology and the Internet and other technologies to flourish to solve this problem provides an effective solution. In this thesis, the smart safe driving system based STM32 chip, which can effectively reduce the traffic in the rear-end and rear-end accidents, can achieve automatic cruise function, but also can be further used for research on urban intelligent autopilot network.This paper describes the current situation and analyze the data traffic accidents incentive is to get the maximum safe driving distance, and thus lead to the subject of safe driving intelligent control system, described the significance of this topic. This topic uses the mobile phone app to control the smart car to start, stop and adjust speed. On this basis, the control of the car(B) is greater than the speed of the smart car(A) travel. When the car driving B will detect the distance between the vehicle and the vehicle speed at the same time, through the Bluetooth module to accept A before the car speed. These data based on the traffic safety control system calculates a minimum longitudinal safe driving distance, when the B car more than this distance will automatically slow down, and to the B car driver a voice alarm, avoid rear end accidents; and forward car a Bluetooth transmission alarm signal that a car driver to take timely security measures to avoid rear end.Then introduced the relevant aspects of domestic and foreign research situation, and describes the content of the research projects and organization of work: firstly introduces the design of hardware systems to modular design introduced the core control unit STM32 minimum system modules, motor module, servo module design speed detection module, LCD display module, ultrasonic module, data transmission module. Secondly, it introduces the algorithm and implementation process of the task involved. Then introduces the implementation process of the subject software system, using C language functions of the above each module. After overall debugging, the model car can complete the scheduled tasks, and can be extended with good function. Finally, the research of this subject were summarized and future research directions are suggested.
