Analysis of handling stability for electric-driven articulated truck based on co-simulation

On the basis of the establishment of articulated truck model and hydraulic steering system model, this paper establishes optimal direct yaw moment control strategy based on the main and auxiliary control variables. The main control variables are side slip angle and yaw rate of vehicle, and the auxiliary control variable is the articulated angular acceleration. The handling and stability of articulated truck and the oil pressure fluctuations of the hydraulic steering system are studied under the control strategies based on co-simulation. The results of the study indicate that the control strategy using the main and auxiliary control variables effectively solves the response delay issues of control moment, vehicle handling and stability are improved when subjected to external disturbance during the driving process, and the oil pressure fluctuations of the hydraulic steering system reduced significantly.
