What is the role of the main control board in the Displayer Control Panel of Pedal Assist E-Bike in the system?

The main control board of the Displayer Control Panel of Pedal Assist E-Bike is responsible for receiving signals from various sensors, such as pedaling frequency sensors, torque sensors, speed sensors, etc. These sensors monitor the rider's pedaling action, force and vehicle operation status in real time. The main control board processes and analyzes these signals to provide a basis for subsequent control instructions.

Control instruction output Based on the received and processed sensor signals, the main control board calculates the corresponding control instructions through the built-in control algorithm. These instructions will be passed to the motor controller and battery controller to achieve intelligent control of the motor and battery. For example, according to the pedaling frequency and torque signals, the main control board can adjust the output power of the motor to provide appropriate assistance; according to the battery power and vehicle operation status, the main control board can control the battery charging and discharging process to extend the battery life.

The main control board has a 1:1 power assist function, which can give a corresponding proportion of motor power according to the rider's pedaling force, making riding easier. Accurate speed regulation is achieved through advanced electronic technology and microprocessors to ensure that the driver can flexibly adjust the vehicle speed according to needs. Supports multiple riding modes, such as cruise mode, to enhance the riding experience; for mountain riding, the three-speed function provided by the main control board can make the motor more powerful when running at low speed.

The main control board has multiple safety protection mechanisms, such as short circuit protection, overheat protection, overcurrent protection, overvoltage protection, undervoltage protection, etc. When the system is abnormal, the main control board can detect it in time and take corresponding protection measures to ensure the safety of the vehicle and the rider. For example, when the battery voltage is too low, the main control board will start undervoltage protection to prevent excessive discharge of the battery; when the motor current is too large, the main control board will perform overcurrent protection to avoid damage to the motor.

The main control board communicates with other components through the communication interface to realize information interaction and sharing. For example, it communicates with the display screen to display the vehicle's operating status, power, speed and other information, so that the rider can understand the vehicle situation; it communicates with the buttons to receive the rider's operating instructions, such as turning on and off, switching modes, etc.
