基于STC15单片机的汽车灯光系统设计与仿真
Design and Simulation of an Automotive Lighting System Based on STC15 Microcontroller
摘要
Abstract
To address the issues of high cost and limited functionality in current automotive intelligent lighting systems,a low-cost vehicle lighting system using the STC15W4K32S4 microcontroller as the core controller is designed and simulated.The system incorporates three key functions:automatic light adaptation,ultrasonic obstacle avoidance,and manual mode switching.Besides using buttons to simulate manual control of light modes and turn signals,in automatic mode,a photoresistor collects ambient light intensity.After conversion by the ADC(Analog-to-Digital Converter)module,the system automatically switches between high and low beams.An ultrasonic module detects forward distance to trigger obstacle avoidance warnings.A multi-task scheduling and state machine management algorithm is employed by the overall control process to effectively coordinate the concurrent operation and mode switching of various functional modules.Software programming is completed using Keil C51,and the hardware simulation environment is built with Proteus to achieve system function simulation.Test results show that the system stably achieves light switching triggered at an illumination threshold(100 lux)in automatic mode,obstacle avoidance responses triggered at a specific distance threshold(100 cm),and basic control in manual mode.It meets the basic functional requirements of a vehicle lighting system while providing relatively intelligent auxiliary control,offering technical reference for developing low-cost intelligent vehicle auxiliary devices and retrofitting traditional lighting systems.关键词
