Equipment that relies on current or electromagnetic fields for normal operation, as well as equipment that can generate, transmit, and measure current and battery fields, and whose rated voltage does not exceed 1000V AC or 1500V DC. The overall structure of commonly used cars is basically composed of the following four parts: engine, chassis, body, and electrical and electronic equipment. Automotive electrical and electronic equipment mainly includes power supply, engine starting and ignition systems, lighting, signaling, electronic control equipment, etc. In modern cars, electronic technology has undergone a leap in development. At present, electronic devices such as electronic ignition, engine power output control (EPC), engine electronic injection system, anti lock braking system (ABS), speed sensitive steering system (SSS), satellite navigation system (GPS), safety airbag system (SRS), and automatic diagnostic device are widely used in automobiles, especially in sedans, greatly improving the reliability and safety performance of sedans. With the continuous development of electronic technology, cars will become more electronic and intelligent
