Abstract: In order to improve the high-speed stability of distributed electric drive articulated heavy vehicles, a direct yaw torque hierarchical controller has been designed in conjunction with distributed electric drive technology. The upper layer is a sliding-model control-based decision control for the additional yaw torque. The lower controller adopts the equal-proportional distribution method to allocate the torque of the wheels. Finally, the effectiveness of the control strategy was verified and analysed with the co-simulation platforms of TruckSim and MATLAB/Simulink, and the working condition of double lane change (DLC) was selected. The results show that the stability of both the tractor and trailer of the designed SMC distributed electric drive articulated heavy-duty vehicle is improved, effectively improving the lateral stability of the distributed electric drive articulated heavy-duty vehicle.

Keywords: articulated heavy vehicle; distributed electric drive; SMC; sliding mode control; lateral stability; torque distribution.
