Working principle of electric four-wheel controller
Author:
The electric four-wheel controller is mainly composed of two parts: drive module and control module. The drive module is responsible for receiving control signals, converting electrical energy into mechanical energy, and outputting the mechanical energy to the drive motor to realize the forward or reverse of the vehicle. The control module is responsible for receiving information from on-board sensors and controllers, performing data processing and sending control signals to control the speed and direction of the vehicle.
First, the composition of the electric four-wheel controller.
The electric four-wheel controller is mainly composed of two parts: drive module and control module. The drive module is responsible for receiving control signals, converting electrical energy into mechanical energy, and outputting the mechanical energy to the drive motor to realize the forward or reverse of the vehicle. The control module is responsible for receiving information from on-board sensors and controllers, performing data processing and sending control signals to control the speed and direction of the vehicle.
The working principle of the 2. drive module
1. Speed control of drive motor
The speed control of the drive motor is the most basic control process of the electric four-wheel controller. The controller adjusts the speed of the motor by controlling the phase sequence and duty cycle of the motor. When the controller needs to accelerate the vehicle, it will increase the phase sequence and duty cycle of the motor, so that the motor outputs more torque, thereby realizing the acceleration of the vehicle.
2. Motor output torque control
The output torque control of the drive motor is another key process to achieve vehicle motion. The controller adjusts the torque output by the motor by controlling the current of the motor. When the controller needs to improve the climbing performance of the vehicle or achieve higher acceleration, it will increase the current size to increase the output torque.
Third, the working principle of the control module
1. Vehicle speed control
Vehicle speed control is another important function of the electric four-wheel controller. The controller calculates the speed information of the vehicle by receiving signals from on-board sensors (such as wheel speed sensors), and adjusts the output torque and speed of the motor according to the control signal to achieve the purpose of controlling the speed of the vehicle.
2. Steering control
The controller realizes the steering control by controlling the phase sequence and duty cycle of the motor. When it is necessary to turn to the left, the controller will reduce the phase sequence and duty cycle of the left motor, while increasing the phase sequence and duty cycle of the right motor, so that the vehicle turns to the left.
IV. Analysis of Advantages and Disadvantages
1 Advantages
The electric four-wheel controller can realize more precise control. On different roads, the output torque and speed of the four motors can be adjusted independently to make the vehicle run more smoothly. Moreover, the brake system of the electric four-wheel controller can distribute the braking force to different tires, improve braking efficiency and ensure driving safety.
2. Disadvantages
The cost of the electric four-wheel controller is relatively expensive. After installation, it will increase the total weight of the vehicle and reduce the cruising range of the vehicle. Since the electric four-wheel controller needs to receive signals from sensors for data processing, and then send control signals to the motor, there will be a certain delay, which affects the response speed of the vehicle.
V. Future Development Direction
With the rapid development of the electric vehicle market, the electric four-wheel control technology will continue to upgrade. In the future, the electric four-wheel controller will strengthen the integration with the on-board automatic driving system to achieve more intelligent control. At the same time, optimizing the algorithm of electric four-wheel controller, improving the control accuracy and reducing the delay problem will become an important research field in the electric vehicle industry.

This paper introduces the composition and working principle of the electric four-wheel controller in detail, analyzes the working principle of the electric four-wheel controller from the two aspects of the drive module and the control module, and discusses the advantages and disadvantages of the electric four-wheel controller and the future development direction. I believe this article can help you to further understand the development trend of electric vehicle technology.
