MEMS Gyroscopes Development and Application Overview on Intelligent Vehicles

With the development of automobile intelligence and automatic driving, the measurement of vehicle motion angular velocity is not only of great significance for improving the active safety, intelligent control and comfort of automobiles, but also an indispensable reference for the control of automatic or unmanned automobiles. Firstly, aiming at the requirements of chassis safety control, navigation control, lane keeping, passive safety and other automotive electronic control systems for angular velocity measurement in Intelligent vehicles, this paper studies, analyzes and compares the characteristics and application status of various micro-electromechanical gyroscopes, and the principle and performance of micro-electromechanical gyroscopes, including micro-vibration gyroscopes, fluid gyroscopes, solid micro-gyroscopes, suspended rotor micro-gyroscopes, optical micro-gyroscopes, atomic gyroscopes. This paper holds that micro-vibration gyroscopes, fluid gyroscopes, solid micro-gyroscopes and electrostatic suspension rotor micro-gyroscopes are most likely to be used in automobile systems in the short term, while atomic gyroscopes have good research prospects.
