Title Electric bicycle controller system detect program designing
Abstract
Currently on the market for electric bicycle driving mainly adopts brushless DC motor, the design begins from the Principle and structure
of this brushless DCmotor, describes the motor speed regulation methods, introduces the brushlessmotor position sensor on the
mainstream, and PWM control method are discussed. Then designs the electric vehicle controller of several functional modules of the hardware part, The main control chip is STM8S single chip microcomputer, gives the overall design diagram of Electric bicycle. The current detection, brake, turn, power sensor

detection circuit of the hardware circuit design, then the
software design of electric vehicle controller modules,
includingspeed control, power tube self-test, over current protection etc.Finally, thepractical tests on the speed control system gives
the control of armature terminal voltage,Holzer signal and rotary
handle degree of rotation not simultaneouslythe armature winding voltage. And the corresponding waveforms are analyzed at last.
