Abstract: This design of mold vehicle controller is based on control technologies of single-chip microcomputer and PWM direct current motor. The controller can receive and judge the main control signals from the imitate driving room and put out signals to control the mold vehicle according to different main control signals, such as headway, retreat, accelerate, decelerate, turn a corner and put on brakes, etc. Adopting 16-bit single-chip machines of Lingyang to control slice outside 8253 to put out signal of PWM, the output signal has characteristics of small error, high control series and good stability.

Key words: single-chip microcomputer of Lingyang, timer, PWM
