Intelligent electric vehicles is one of the embodiment. The system simulation based on 51 single chip microcomputer remote control car design. 89 s51 microcontroller is an 8 bit microcontroller, the ease of use and the ISP online programming function is well received by the vast number of users. Here is how to use 89 s51 single-chip microcomputer to realize the wireless remote control car design. The purpose of this system with the requirement of design topics, using 89 s51 microcontroller as the control core, adopted L298N control of the motor car, devices using bluetooth wireless remote control module; Design based on the complete hardware and software system, a good implementation before and after the electric car, turn around, and parking. The circuit of the whole system has simple structure, reliable performance is high, basically meet the design requirements. Key words: single chip microcomputer; Bluetooth wireless remote control; The PWM speed regulation; L298N; . 目 录 一、前 言 1 二、方案设计与论证 3 2.1 直流调速系统 3 2.2 无线控制系统 4 2.3 系统总体控制方案设计 5 三、硬件设计与实现 6 3.1 89S51单片机 6 3.2 系统运动控制部分设计 7 3.3.1 电机选型 7 3.3.2 L298N驱动电机 7 3.3 蓝牙无线电发射接收模块介绍 9 3.4单片机的最小应用系统设计 11 3.5 PWM调速系统 12 四、软件设计 14 4.1 系统软件设计说明 14 4.2 程序设计 14 4.3 手机蓝牙控制端的设置 15
