What Systems Comprise the Chassis?

[DelCecilia]

Automotive chassis electronic control systems primarily consist of signal input devices, electronic control units, and actuators. Below is relevant information: 1. Voltage Signals: Voltage signals are categorized into analog and digital signals. Analog signals refer to infinitely variable voltage signals within a given range, with most sensor signals being analog voltage signals. Digital signals represent one of two states: on/off, high/low, or present/absent. In automotive electronic control systems, due to the adoption of computer technology, signal processing speed and capacity have significantly improved compared to traditional analog circuits. However, the central processing unit of a computer can only receive digital signals. 2. Electronic Control Unit (ECU): The electronic control unit provides reference voltage to various sensors, receives electrical signals from sensors or other devices, and performs storage, computation, and analysis on the received signals before issuing commands to actuators. Actuators complete the required mechanical actions based on the control signals output by the electronic control unit to achieve adjustment and control of a particular system.
