Which Parts of a Car Require Chips?
1 Answers
According to their types, they can be divided into four major categories: functional chips MCU (Micro Control Unit), power semiconductors (IGBT, MOSFET, etc.), sensors, and others. The specific descriptions are as follows: 1. MCU: The full name in automobiles is Motor-Control-Unit, which translates to "Motor Control Unit" in Chinese. It is the module that controls motor actions, primarily connecting and controlling various peripheral circuits and interface circuits in the car. It acts as the brain of the car, controlling all electronic systems, including suspension, engine control systems, in-vehicle infotainment, wipers and windows, electric seats, and other components that require electricity. 2. Power semiconductors (IGBT, MOSFET, etc.): The full name of the IGBT chip is "Insulated Gate Bipolar Transistor." It is a composite fully controlled voltage-driven power semiconductor device composed of BJT (Bipolar Junction Transistor) and MOS (Metal-Oxide-Semiconductor Field-Effect Transistor), mainly used in new energy vehicles. Functionally, the IGBT chip serves as the power conversion device used by MCU chips, enabling power conversion in electric drive systems to improve power efficiency and quality. Therefore, it is also known as a super switch for controlling electrical energy. 3. Sensors: Automotive sensors are input devices for the car's computer system. Their role is to convert various operational conditions of the car, such as speed, temperature of various media, and engine operating conditions, into electrical signals for the computer, ensuring the car operates in the best possible state. 4. Others: Since traditional automotive functional chips are only suitable for localized functions such as engine control and battery management and cannot meet the high data volume requirements for intelligent driving-related computations, in recent years, with the popularization of intelligent driving assistance systems, global chip giants have entered the automotive industry, introducing main control chips with AI computing capabilities.
