四轮驱动汽车车轮驱动防滑的牵引力控制仿真分析
Simulation Analysis of Traction Control for Anti-slip Control of Four Wheel Drive Vehicle
摘要
Abstract
In order to improve the vehicle dynamics and driving stability of full-time 4WD vehicle, dynamic models of engine,inter-axle and inter-wheel electronic limited-slip differential and hydraulic system were established,engine target torque fuzzy controller,inter-axle torque distribution fuzzy controller and inter-wheel torque distribution PID controller were designed.Integrated traction con-trol strategy was proposed,and the acceleration performance was analyzed by simulating on low-μroad,step-μ road,split-μ road and ramp road.The results indicate that the strategy can regulate the drive torque quickly according to the slip of driving wheels,inhibit the excessive slip of driving wheels effectively,improve the dynamic performance and passing ability on bad roads obviously,and show a good adaptability.关键词
