Simulation analysis of stability control strategy for heavy single tractor

摘要

A 2DOF reference model of heavy single tractor was set up using the yaw rate and the lateral acceleration as control variables based on analysis of tractor instability mechanism. The reference model of tractor was simulation controlled using allocation strategy of braking moment and control strategy of slip ratio with PD algorithm for typical fishhook steering in Trucksim. The simulation results show that this control method is correct and feasible, the control target that enhance tractor stability has been realized.
