Research on Logic Control of Variable Transmission Ratio SBW based on Pan-Boolean Algebra

In order to improve the steering performance of automobiles and make full use of the advantages that Steer by Wire(SBW) can design transmission ratio freely, a variable transmission ratio control strategy based on Pan-Boolean algebra is proposed. Based on the 2 DOF vehicle steering model, the Matlab/Simulink software is used to model and simulate the SBW system, and is compared with the same parameter fuzzy control variable transmission ratio method. The results show that at low speed-high angle, high speed- low angle, the sideslip angle of this method is smaller than that of fuzzy control, the overshoot of yaw velocity transient response is less, and the steering sensitivity and vehicle handling performance of this method is more stable than that of fuzzy control.
