Abstract: A direct yaw moment differential braking control strategy based on fuzzy Proportion、Integral、Differential (PID) control is proposed for the dangerous situation of double-trailer train under high-speed overtaking condition, such as lateral instability, trailer folding and tail-throwing. Two kinds of lateral stability control strategies for differential braking were designed, namely single-control mode controlled only by tractor and multi-control mode controlled by both tractor and trailer, aiming at the lateral deflection angle and yaw velocity deviation and deviation change rate of the TruckSim nonlinear model and the four-degree-of-freedom linear model respectively. The effectiveness of the control strategy was verified through the co-simulation of MATLAB/Simulink software and TruckSim software and the Hardware-in-the-Loop (HIL) platform. The results show that, in high-speed overtaking conditions, the lateral stability control system of multi-control vehicles is better able to reduce the lateral declination angle, yaw speed, articulated angle and Rearward Amplification (RWA) coefficient of the vehicle than that of uncontrolled vehicles and single-control vehicles, and is significantly better in improving the lateral stability of double-truck trains.

Key words: double-truck train, direct yaw moment control, differential braking, fuzzy Proportion、Integral、Differential (PID) control, hardware-in-the-loop validation
