What are the functions of the motor control system of new energy vehicles?

In short, the motor controller of pure electric vehicles has a variety of functions, including motor operation mode control., speed and torque control, brake energy recovery, temperature and fault protection, as well as data acquisition and diagnosis, etc.

The drive motor controller of hybrid new energy vehicles mainly has the following functions: energy management: control the flow of vehicle energy, including battery charging and discharging, engine start-stop and auxiliary device control, etc. Motor drive: Control the speed and torque of the motor, so that the vehicle can obtain the best power performance and energy efficiency under different working conditions.

Motor Control System - The main function of the MCU Motor Controller (Micro Controller Unit) is to receive torque instructions from the whole vehicle controller, and then control the drive motor to work according to the set direction, speed, angle and response time.

For electronic control systemTo control batteries, motors and other components, its functions include: battery management, engine, motor energy management, etc. The electronic control system is composed of ECU and other control systems, sensors and other sensing systems, driver intention recognition and other subsystems.

The role of electric vehicle motor controller - function introduction The motor controller is equipped with IGBT junction temperature estimation, variable load frequency and over-modulation technology. The system has high efficiency, strong power and high reliability, and has CAN wake-up and hibernation functions to reduce the static power consumption of the motor controller and avoid battery feeding.

The improvement of electronic control efficiency can significantly improve the economy of pure electric vehicles. Electronic control, in a broad sense, electronic control includes the whole vehicle controller, motor controller and battery management system. This article introduces the working principle and optimization scheme of motor control.

[Pacific Automobile Network] The main function of the electronic control system of new energy vehicles is to control the output torque of the motor and make the vehicle run. The whole electronic control system is comparable to the engine and engine controller of fuel vehicles.

Other functions: including temperature control, noise control, waterproof and dustproof, etc.In a word, the drive motor controller of hybrid new energy vehicles is a very important part of the whole vehicle system. Its function and performance directly affect the power performance, energy efficiency, safety and other aspects of the vehicle.

Motor Control System - The main function of the MCU Motor Controller (Micro Controller Unit) is to receive torque instructions from the whole vehicle controller, and then control the drive motor to work according to the set direction, speed, angle and response time.

What does the motor control system consist of?

1. The drive motor control system is mainly composed of motor controller, drive motor, sensor, etc. The motor controller is controlled by a key ignition switch, which has weak, strong, stop, charging indicator lights, and fault indicator lights.It realizes the control of the drive motor through a series of switches, hardware circuits and logic controls.

2. Motor controller (driver): The motor controller is the brain of the motor drive system. It receives external signals, such as user input or sensor feedback, and controls the operation of the motor. The controller is responsible for adjusting the speed, direction and torque of the motor to meet the needs of specific applications.

3. The automatic control system is mainly composed of four links: controller, controlled object, actuator and transmitter. Controller: The wiring of the main circuit or control circuit and the resistance value in the circuit can be changed in a predetermined order to control the start-up, speed regulation, braking and reverse master command device of the motor.

4. [Pacific Automobile Network] The motor control system is mainly controlled by the motor.It is composed of a device, a drive motor, an electronic shift control device, an acceleration pedal, and also includes high-voltage wires, signal lines and cooling systems. The motor drive system of new energy vehicles includes power electronic converters and corresponding controllers.

5. It consists of three parts: signal input device - various sensors, which collect the signals of the control system and convert them into electrical signals and transmit them to the ECU. The electronic control unit - ECU provides reference voltage to each sensor, accepts sensor signals, and the actuator issues instructions after storage, calculation and analysis processing.

6. It consists of three parts: executive components, measuring components and controls.

What is the drive motor control system generally composed of?

1. The drive motor is a complex system, which is usually composed of multiple parts to realize its functions. The main components include: Motor: This is the core part of the motor, which converts electrical energy into mechanical energy, thus driving the mechanical system.

2. The motor control system is usually composed of the following main components: Controller: The controller is the core of the motor control system, which is responsible for receiving and processing instruction signals from the outside, and generating corresponding control signals according to the set control algorithm.

3. The motor drive system is mainly composed of motor, power converter, controller, detection sensor and power supply and other parts. The function of the motor drive system refers to the idling control of the motor by controlling the rotation angle and operating speed of the motor to achieve the control of the occupy ratio.

4. Controller: The controller that drives the motor is a key component used to control the operation of the motor. The controller receives control signals from the outside and generates the current and voltage waveforms required to drive the motor through appropriate control algorithms and circuits to achieve the speed, steering and torque control of the motor.

Introduction to the electronic control system of new energy vehicles

The electronic control system can be divided into the following four parts: 1) Engine and power transmission centralized control system, including engine centralized control system, automatic transmission control system, defense Hold-and brake and traction control system, etc.

On the basis of the design of the electronic control system of new energy vehicles, the electronic control system of the whole vehicle of new energy vehicles is divided into two parts: high-voltage electronic control system and low-voltage electrical control system.

In the field of new energy vehicles, there are three major parts of automobiles. These three parts are batteries, motors and electronic control. Electronic control is actually equivalent to the gearbox in fuel vehicles. When buying new energy vehicles, if you want to achieve the purpose of saving, the electronic control system can be said to be very important.

The electronic control system of new energy vehicles, in a small way, refers to the whole vehicle controller. In general, it includes the whole vehicle controller, battery management system, drive motor controller, etc.

The electronically controlled new energy vehicle motor and electronic control system of new energy vehicles replace the function of the traditional engine gearbox, and its performance directly determines the main performance indicators of electric vehicles such as hill climbing, acceleration and maximum speed.

The importance of electric motor control New energy vehicles as traditional fuel vehiclesThe replacement, its main electrical system is the "three electricity" of the electric powertrain system extended on the basis of the "three small electricity" (air conditioning, steering, braking) of traditional automobiles - battery, motor, electronic control.
