Abstract: A pure electric bus controller based on STM32 is designed through analyzing the function and running state of pure electric bus control. The function of each module of the controller is analyzed,and the power supply circuit and voltage detection circuit are designed. The controller adjusts the speed of the DC motor through outputting pulse width modulation with different duty cycles.The information collected by the sensor is transmitted to the microprocessor in real time through the CAN bus,and the microprocessor analyses the collected information and sends commands through CAN bus to control the running state of the bus safely,accurately and in real time.

Key words: STM32, electric bus, controller, pulse width modulation
