汽车自动变速器教学演示装置单片机控制系统设计

System Design with Microcomputer Control on Automatic Transmission Teaching Instrument of TOYATA A240E

在汽车自动变速器教学演示装置控制系统设计中,利用AT89C52单片机控制发光二极管来模拟自动变速器展开图上面的各挡位油路及其自动变速功能和故障现象。利用键盘和LED显示器进行人机交互,这样就将复杂抽象的自动变速器换挡及复杂的油路动作过程简单化。此设计在教学当中,能使学生对难懂的自动变速器原理及换挡过程各元件的动作很容易接受,并能在较短时间内掌握汽车自动变速器的工作原理。

In the design of the control system of a teaching experimental device for the Automatic Transmission of car, the AT89C52 single chip is used to control the LED for the purpose of simulating, on an expanded view of the Automatic Transmission,the oil circuit of different gears, its automatic speeding function and the trouble phenomenon. The adoption of keyboard and LED monitor for the communication between people and the computer makes the gear shift and the complex oil circuit action more simple and easy. Therefore, it＇ s much more acceptable for students to understand the principle of the Automatic Transmission and the action during the gear shifts and know well the operating principle of the speeder much faster.
