Research on Steering Transmission Ratio Based on Person Correlation Analysis
Aiming at the vehicle that has lost its driving ability,An effective method is explored to detect whether there is deviation in the steering system under static conditions,especially the key evaluation inde-xes.A set of steering transmission ratio measurement system is used for real vehicle test,and the angle of steering wheel rotation,the force of steering wheel rotation and the angle of wheel rotation are collected synchronously.Based on the real vehicle test data of 8 motor vehicles and 3 different types of vehicles,the steering transmission ratio of vehicles is studied by using the Person correlation analysis method.By divid-ing the experimental data into three working conditions and analyzing the correlation one by one,the consis-tency of the change of steering transmission ratio is fully reflected,which lays a foundation for further ex-ploring the feasibility of steering transmission ratio as a characterization parameter of steering performance.
