Study on the Composite Steering Matching Characteristics of Distributed Independent Drive Vehicles

In order to study the compound steering mechanism of the distributed independent electric drive vehicle and improve the steering maneuverability and handling stability of the vehicle, taking a certain 8 × 8 independent electric drive vehicle as the object, the vehicle simulation model, the distributed independent electric drive control model and the compound steering control model of the vehicle were constructed, and the research was carried out on the basis of geometric steering by actively superimposing the speed difference angle on the driving wheel. In other words, the method of applying the virtual steering angle of wheel forward was used to study the influence of geometric steering mode and compound steering mode on the steering radius of vehicle under the same steering angle. Through the dynamic simulation under different driving conditions, combined with the vehicle stability parameters such as yaw angle, lateral acceleration, sideslip angle of the center of mass, the influence of compound steering on vehicle handling and stability was studied, and finally the matching characteristics of compound steering of distributed independent electric drive vehicle were obtained.
