Research on Correction Model of Automobile Angular Velocity Based on Graph Optimization

This paper proposes a vehicle angular velocity correction model based on graph optimization. The errors caused by the manufacturing process of the wheel gear ring will produce a fixed spike noise to the wheel angular velocity. We propose a graph-based optimization method to reduce the noise caused by the gear ring and improve the estimation accuracy of the wheel angular velocity.The experimental results show that the spike noise is eliminated by graph-based optimization and the data fluctuations are reduced.We can draw a conclusion that the wheel angular velocity can be corrected by this method.
