What are the components of the automotive electrical system

1. The components of the automotive electrical system include seven major parts, namely: charging system, start-up system, ignition system, lighting and signal system, instrument system, Auxiliary electrical system and electronic control system.The charging system consists of a battery, a voltage regulator and an alternator, etc., which mainly provides the power needed for the system to work when the car starts and runs.

2. Power supply system The power supply system includes storage batteries, generators and their regulators.

3. The power supply system includes batteries, generators and regulators. The generator is the main power supply. When the generator works normally, the generator supplies power to all vehicle electrical equipment and charges the battery at the same time. The function of the regulator is to keep the output voltage of the generator constant. The start-up system includes a series excitation DC motor, a transmission mechanism and a control device.

4. The automotive electrical system consists of seven major parts, which are charging system, starting system, ignition system, lighting and signal system, instrument system, auxiliary electrical system, and electronic control system.The following is a brief introduction to the composition and function of each system. Charging system composition: composed of storage batteries, voltage regulators and alternators, etc.

working process of automotive electronic control system automotive circuit control principle

1. Second, electronic control systemThe working principle of Tong is the air flow meter and throttle position sensor related to the engine speed sensor. The relevant signals of a series of sensors such as the camshaft position sensor are used to judge the working status of the engine.

2. The working principle of the engine electronic control system is: when the engine starts, the ECU quickly enters the working state, removes some programs or steps from RAM, and enters the central processing unit (CPU). These programs can control gasoline injection, control ignition timing, control idling state, etc. Under the control of the CPU, the instruction signals are looped one by one.

3. The working principle of the body electronic control system mainly includes the following aspects: sensor perception: the body electronic control system senses the state and changes of the internal and external environment of the vehicle through various sensors.

4. The working principle of the automotive electronic control system is to take the engine speed and load as the basic signals to reflect the actual working conditions of the engine. Determine the relevant fuel injection volume and fuel injection pulse width data according to the fuel injection volume and fuel injection timing pulse width corresponding to each working condition of the engine.

5. The working principle is based on the feedback data of the sensor, and the computer then controls the actuator. The sensors of the electronic control system of fuel vehicles include: crankshaft sensor, camshaft sensor, oxygen sensor, intake pressure sensor, air flow meter, water temperature sensor, explosion sensor, throttle position sensor.

6. The working methods of automobile electronic control systems are similar. For example, the engine system, the engine computer is equivalent to the human brain, and the sensor is equivalent to the human touch nerves and eyes.The known signal is transmitted to the computer, and the computer then controls the work of other actuators, so that the vehicle can operate normally.

What are the functions of the automotive electronic control system

1. The automotive sensors are arranged in different positions of the automobile. The main function is to provide the automobile control system with information on various working conditions of automobile operation, such as engine speed, speed The valve opening, coolant temperature, etc. Sensors with the same function also have different structural forms in different cars.

2. The automotive electronic control system can be divided into the following four parts: 1) Engine and power transmission centralized control system. Including engine control system, automatic transmission control system, anti-lock braking and traction control system, etc. 2) Integrated control and safety system of the chassis.

3. The electronic system of the automobile can provide a role for the power performance, economic performance and emission performance of the automobile. It is divided into engine electronic control system, chassis electronic control system, body electronic control system, etc.

4. The electronic automatic transmission takes the electronic control system as the control center, which has a shorter control time, more accurate gear shifting, and more perfect matching, reducing the frequent operation of the driver, reducing the labor intensity, and making it easier for users to get a good driving experience.

5. There are three main functions of the engine electronic control system: self-diagnosis function---self-diagnosis and alarm system. In the engine control system, the electronic control unit (ECU) is equipped with a self-diagnosis system to monitor the work of various parts of the control system.

The basic composition and role of each part of the automotive electronic control system

1. The automotive electronic control system generally consists of three parts in terms of hardware structure: sensor, electronic control unit (ECU) and actuator. When the car is running, each sensor constantly detects the operating condition information of the car and transmits this information to the ECU in real time through the input interface.

2. All electronic control systems of all cars are composed of three parts: sensors, controllers and actuators. Sensor: It mainly collects the signals of various parts required by the controller to provide data support for the controller command actuator.

3. Composition of sensor and actuator. First, the electronic control unit is a car.The general command of electronic control comprehensively analyzes and processes the relevant signals input by each sensor and the signals feedback from the actuator, and then maintains the best working state of the vehicle and engine.

4. The electronic control system of the car is composed of sensor engine ecu driver and control program software and other parts. First, this includes electronic fuel injection system brake, anti-lock control system, anti-side slip system, electronic control suspension system, electronic control automatic transmission, electric Sub-power steering and other related systems.

5. The electronic control system of the automobile is composed of sensor engine control module, driver and control program software and other parts. First, the electronic control system of the automobile is roughly divided into four parts, namely the engine electronic control system, the chassis comprehensive control system, the body electronic safety system and information. Communication system.
