本科生毕业设计（论文） PAGE V 基于CAN总线的轿车车灯控制系统及雷达系统的设计 摘 要 随着现代汽车技术的日益发展，汽车电子装置不断增加，汽车综合控制系统中需实时交换的各种控制信息随之越来越多，传统线束技术已远远不能满足这种需求，汽车总线控制技术应运而生。本设计主要实现车灯控制系统和雷达系统的智能化。 本设计以单片机P87C591为核心构建硬件平台，通过CAN总线模块接收和发送报文、光敏传感器采集光信号和湿度传感器采集湿度信号，传感器采集的信号输入给AD转换器，再传输给单片机，由单片机对信号进行分析处理，输出控制信号控制汽车车灯的亮灭，雷达系统通过超声波的发送和接收模块，把信号传给A/D转换器，在由单片机对信号进行分析处理，控制报警电路报警。在软件设计上，有CAN总线收发系统，灯光系统，雷达系统和测距系统等。 本系统实现了汽车车灯控制的智能化和雷达系统的测距功能，再有障碍物靠近车辆时，报警电路能够及时报警，保证了汽车在行驶过程中的汽车的安全行驶，大大提高了车辆在行驶中的安全性和可靠性。 关键词:CAN总线，P87C591，车灯控制，雷达系统 Abstract With the development of modern automobile, automobile electronic device increases ceaselessly, all sorts of information control will be more and more real-time exchange need comprehensive automobile control system, the traditional wiring technology has far can not meet this demand, vehicle bus control technology emerge as the times require. This design is mainly the realization of intelligent lighting control systems and radar systems. The P87C591 single-chip design as the core of the hardware platform, receiving and sending newspaper, a photosensitive sensor signal collection and humidity sensor and humidity signal through the CAN bus module, signal sensor inputs to the AD converter, and then transmitted to the microcontroller, the signal was processed by SCM, the output control signals to control the vehicle lamp light out, radar system by ultrasonic sending and receiving module, sending a signal to the A/D converter, by the microcontroller on the signal analysis and processing, control alarm circuit alarm. In software design, CAN bus transceiver system, lighting system, radar system and ranging system. This system has realized the ranging function of intelligent and radar system of automobile light control, another obstacle to the vehicle, the alarm circuit can alarm in time, ensure the safety of vehicles in the automobile driving process, greatly improving the safety and reliability of the vehicle.
