Mems (micro-electromechanical system) sensor; there are three MEMS technology products: infrared sensor, magnetic sensor, angle measuring sensor; in high-end cars, about 25 to 40 MEMS sensors;
This article refers to the address: http://
1) High-precision production of high-volume MEMS sensors with high reliability and low unit price, especially suitable for application in automotive electronic control systems;
2) a car airbag sensor in an airbag;
3) MEMS automotive micro-accelerometer is replacing the previous electromechanical acceleration sensor
4) MEMS gyroscope applications in high-end vehicles include: suspension control, tumbling
5) Automotive MEMS pressure sensor and tire pressure automatic monitoring system, MEMS pressure sensor is suitable for any type of tire, embed a small piece of pressure sensitive chip in the tire sidewall, automatically measure tire pressure, temperature, speed and other data, and use A specific code is sent out.
6) MEMS applications in engine management systems
7) Micro-mechanical gyro is a vibrating angular rate sensor, which has attracted much attention in the automotive field. It is mainly used for GPS signal compensation and vehicle chassis control systems for car navigation;
8) EFI of the electronic fuel injection system of the vehicle should use multiple pressure MAP sensors to monitor the absolute pressure of the engine intake differential, improve its power performance, reduce fuel consumption and reduce exhaust emissions.
9) Micro-silicon piezoresistive MEMS pressure sensor can be used in engine exhaust gas circulation system instead of ceramic capacitive pressure sensor;
10) Pressure measurement in automotive air conditioning compressors is also a large market for MEMS.
11) Air pressure measurement in the cylinder, bursting control;
