Description

technical field [0001] The invention relates to the technical field of vehicle sensors, in particular to a vehicle acceleration and angular velocity measurement system. Background technique [0002] Acceleration and angular velocity are important physical quantities for sensing the running state of a car. In electronic control systems such as automatic variable speed control, electronic stability control, electronic navigation, and slope boosting of automobiles, acceleration and angular velocity are widely used as important parameters in the control system. At the same time, in the vehicle handling and ride comfort evaluation experiments, accurate collection of acceleration and angular velocity is a key step in evaluating vehicle quality. Therefore, the precise measurement of acceleration and angular velocity is extremely important, whether it is in the evaluation of automobile experiments or in the electronic control of automobiles. [0003] The current technology for acce...
