What does the electrical system of a car consist of?

The automotive electronic control system is basically composed of sensors, electronic controllers (ECUs), drivers, and control program software, and is used in conjunction with the mechanical systems on the vehicle (usually integrated with subsystems in the power system, chassis system, and body system), And use cables or radio waves to transmit information to each other, which is the so-called "mechanical and electrical integration". Such as electronic fuel injection system, brake anti-lock brake control system, anti-skid control system, electronically controlled suspension system, electronically controlled automatic transmission, electronic power steering, etc.

The automotive electronic control system can be roughly divided into four parts: engine electronic control system, chassis integrated control system, body electronic safety system, and information communication system. Among them, the first two systems are directly related to the driving performance of the car.

Automotive electronic control systems 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, brake anti-lock braking and traction control system, etc.;

2) Chassis integrated control and safety system. Including vehicle stability control system, active body attitude control system, cruise control system, collision avoidance warning system, driver intelligent support system, etc.;

3) Intelligent body electronic system. Automatic seat adjustment system, intelligent headlight system, car night vision system, electronic door lock and anti-theft system, etc.;

4) Communication and information/entertainment systems. Including intelligent car navigation system, voice recognition system, "ON STAR" system (with functions such as automatic call for help and inquiry), car maintenance data transmission system, car audio system, real-time traffic information consulting system, dynamic vehicle tracking and management system, and information service system (including network, etc.), etc.
