摘要：
To enhance the driving safety caused by cross-wind, the transient analysis model of a car overtaking truck on cross-sea bridge was established using a coupling method of composite wind and moving mesh, and the mechanism of aerodynamic interaction between “wind-vehicle-bridge” in the overtaking processes of a car and the influences on the aerodynamic characteristics of the car were revealed. The overtaking trajectory planning models were developed using a fifth degree polynomial interpolation algorithm, and the longitudinal and lateral coordination motion controllers were developed, using dual fuzzy PID control method for the longitudinal controllers and sliding mode control method of radial basis function network for the lateral controllers. The path tracking capability analysis and driving stability evaluation of the overtaking processes of a car under cross-wind were carried out. The results show that the aerodynamic interference is significantly related to the travelling lanes and positions. The longitudinal and lateral coordination motion controllers have better accuracy and robustness in controlling the path tracking, and the crosswind stability is significantly improved. © 2024 Chinese Mechanical Engineering Society.
