Briefly speaking, the controller is composed of peripheral devices and the main chip (or single-chip microcomputer). Peripheral devices are some functional devices, such as execution, sampling, etc., they are resistors, sensors, bridge switch circuits, and auxiliary microcontroller or application-specific integrated circuit to complete A device that controls the process; a single-chip microcomputer is also called a microcontroller.It is an integrated chip that integrates a memory, a decoder that converts the signal language, a sawtooth wave generator, and a pulse width modulation function circuit, and can turn on the power circuit of the switching circuit. Or cut off, the driving time of the power tube is controlled by the square wave to control the motor speed, the drive circuit, input and output ports are integrated together to form a computer chip. This is the intelligent controller for electric bicycles. It is based on the "fool The appearance of high-tech products.

The design quality and characteristics of the controller, the function of the microprocessor used, the circuit of the power switch device and the layout of peripheral devices, etc., are directly related to the performance and operating status of the entire vehicle, and also affect the performance and efficiency of the controller itself. The controller, used in the same car and equipped with the same battery in the same charge and discharge state, sometimes shows a large difference in driving ability.
