Research on Control Strategy of Traction Control for Four Wheel Drive Vehicle

摘要：

　　In order to improve the performance of four wheel driver vehicle,structural characteristics of inter-axle torque distribution with planetary gear are analyzed,and a dynamic model of four wheel drive vehicle is established.A synthetic control strategy was proposed to achieve the engine throttle control,inter-axle torque distribution control and drive wheel brake control.Traction control system based on fuzzy logic control is designed.The simulation of traction control on split-μ road and low-μ road are carried out.The results show that,the traction control system for four wheel drive vehicle based on fuzzy control can prevent excessive slip of driving wheels,and vehicle traction property and dynamic performance are improved obviously.
