Automotive electrical components refer to the entire electrical and electronic systems of a vehicle, encompassing a wide range such as engine control, powertrain, ADAS (Advanced Driver-Assistance Systems), infotainment, and body control. In recent years, their importance has grown exponentially with the electrification of vehicles and the evolution of autonomous driving technology. Key features include advanced electronic control technology, high safety, reliability, and durability, and close integration with software. Applications are extensive, including ECUs, sensors, actuators, inverters, and Battery Management Systems (BMS). Representative services include hardware and software design and development, functional safety design, evaluation and verification including EMC testing, mass production manufacturing, and supply chain management. These are core components that determine vehicle performance, safety, and comfort, and a balance between quality, cost, and development time is always required.
