With the increase in the number and types of electronic components and the increasing use of complex electronic components in the vehicle, the application of electromagnetic compatibility is becoming more and more important, and it is directly related to the vehicle Safety, energy saving and environmental protection. Electromagnetic interference can not only affect the normal work of electronic devices, but also affect the automotive electrical system itself has become increasingly modern automotive electronics and electrical equipment and automotive electrical and electronic products work properly, while the outside world of electromagnetic interference Will affect the normal work of electronic equipment on the car, so, for the overall design of the car, the automotive electromagnetic compatibility issues must be resolved, at present, the automotive electronics industry and the vehicle is facing the following aspects.
1, with the use of automotive electronic systems and complexity increases, automotive EMC challenges are also rising, for example, the system power supply voltage increases, the increase in vehicle electronic equipment, high-frequency electronic devices more frequently, some of the electronic Module interfaces with existing low-power, low-cost, low-power sensors with poor linearity and zero offset. Since these sensors rely on small-signal operation, electromagnetic interference can be catastrophic for their normal operation.
2, the automotive electrical and electronic systems and components of the sensitivity of the electromagnetic field to a minimum, so that electronic equipment from the car essential mobile communication devices such as mobile phones, GPS and infotainment equipment, and so on the electromagnetic system Interference.
3, to protect electronic equipment from harsh automotive environments such as snow and lightning and dust and other effects, and to ensure that the power supply system from transient, light switch and motor starting and other large load and inductive load interference.
4, to minimize the other car's electronic systems and road systems, electronic facilities, electromagnetic emissions
