[Understanding Automotive] Complete conquest of hysteresis "Hysteresis" is the correct spelling in English, although some may mistakenly write it as "Hysterisis." The name itself can indeed be quite challenging, reminiscent of names from Greek mythology. Perhaps because of this, understanding hysteresis can also be difficult. Today, I'll attempt to write about hysteresis with the expectation of achieving a complete understanding. The translation of "히스테..
[Understanding Automotive] Watchdog Timer What's a watchdog timer? Simply put, you can think of it as a watchdog for your home...? That is to say, it's a function that monitors something and fixes errors when anomalies occur. It plays a role in monitoring whether an MCU (Microcontroller Unit) is stuck in uncontrollable situations like an infinite loop or abnormal stop situations. It's the minimum device that ensures an MCU operates prop..
[Understanding automobiles] About the operating principle of air conditioner (composition) Last time, I explained the big framework of the air conditioning system, but this time, let's see how it functions and what needs to be done. In fact, the best thing to do is to explain it in a video. I'm not good at it. But I'm going to explain it so that we can do "image training" very easily, which we can do well. I hope you read this and draw it in your head and think about how it works. ※co..
[Understanding the Automobile] About HVAC (Air-Conditioning System) HVAC (Heating Ventilation Air Conditioning), or the air conditioning system, is a system that maintains the comfort of a vehicle's interior through functions such as heating, ventilation, and cooling. *It refers to the heating and cooling devices in an automobile. Although commonly associated with cooling, the term encompasses both heating and cooling functionalities. *The importance of HVAC goe..
[Understanding Automotive] What is LIN communication There's LIN (Local Interconnect Network) communication, which always accompanies CAN (Controller Area Network) communication in automobile specifications. Its name does sound rather elegant, doesn't it? explain LIN(Local Interconnect Network) communication is a communication protocol used for various active sensors* and actuators within a car to communicate with control units. It is primarily us..
[Understanding Automotive] Types of Documents and Explanation of Terminology in Automotive Documentation Writing Based on Background As the connectivity, smartification, and proliferation of ADAS and autonomous driving-related functions in automobiles increase rapidly, the use of external open-source solutions is also on the rise. In such cases, the following considerations should be taken into account to address responsibility-related issues and resolve any arising issues in automobiles: Responsibility: The origin and basis ..
[Understanding Automotive] Explanation of Types and Classification of Communication in Specification Document CAN Communication: Records data transmitted and received through Controller Area Network (CAN) communication. CAN communication is widely used in automobiles and other control systems, with this data primarily used for communication with external devices and systems. LIN Communication: Records data transmitted and received through Local Interconnect Network (LIN) communication, which is a simple..
[Understanding Automotive] Types of interfaces defined in AUTOSAR. Reference Interfaces are pathways that enable interaction between two different entities or systems. They are widely used across various fields, with computer technology being one of the primary areas where interfaces are prevalent. In computer science, interfaces facilitate interaction between users and computers, allowing users to manipulate computers and perceive results. Interfaces also play..
