The Design of Electronic Bike Controller based on PIC16F877

Based on PIC16F877 microcontroller as the main control chip electric bicycle controller was studied, with rated voltage of 48V DC power rating of 350W brushless motor for the control of the object, through all kinds of electric bicycle signal detection, processing, and with energy feedback, electronic Flexible brake, cruise, under-voltage protection, speed limits, over-current protection, PID speed control, anti-speed driving, soft-start functions. Gives the main modules of the circuit, introducing an important program modules. To software-based, maximum extent reduce costs and Experimental results show the high performance of the controller.
