Automotive Technology/Electronics & Electrics 썸네일형 리스트형 PCU Powertrain Control Unit During cleaning up my study room, I have found a very old PCU which my project team has developed for Hyundai's A-segment sedan in 2007. This is the scrap after PCB heat-up test, the burnt damage can still be seen in the copper connection between PCB and connector. Nowdays, the size of control unit is much smaller than this one and number of integrated functions are tens of times increased. It i.. 더보기 Coolant Temperature Sensor Our human body has to keep a certain range of temperature (37deg C) for healthy daily life. Like our body, an internal combustion engine is designed to be operated optimally under a certain temperature condition. In general, the coolant temperature stays around 90 deg C for an optimal operation of an engine. If the operation temperature stays out of this designed range, the engine can show sever.. 더보기 Sensors_General A power control system in vehicles works as a system composed with sensors, controller and actuators. We can easily compare any system with our body system. We have sensors, such as, eyes to see, nose to smell, tongue to taste, etc. Our brain analyze the signals from our sensors and make and order to the actuators (our hand, leg, foot, any kind of muscle in our body) for a planned purposes. Nowa.. 더보기 Electronic Control (2) Electronic Control (2) Normally the control system consists of sensor parts which supply the information of moving parts of a vehicle or engine, controller part which processes the signals from sensors and make a proper decision based on the control logic inside of the control program and the actuator part which really does proper actions and generates a necessary movement of a vehicle. Sensors .. 더보기 Electronic Control (1) Electronic Control (1) Together with big technical advance in electronic industry, every side of our life is also being equipped with electronic devices and controllers, and our car is not an exception of this trend. The value of electronic part in our car is getting bigger every year, if electronic vehicle comes to our daily life the automotive industry can be categorized as a part of electroni.. 더보기 이전 1 다음
