用于越野汽车差速锁止控制系统的动力学模型仿真

Study of Vehicle Dynamics Simulate Model Using in Off-road Vehicle Differential Lock Automatic Control System

建立了包括发动机、传动系统、轮胎和整车的动力学模型,并详细给出了各运动方程。通过对该模型进行的仿真计算,所建立的模型可以较精确地反映汽车在几种工况下的动力学性能,为开展越野汽车差速锁止控制研究奠定了基础。

The dynamic model including engine, transmission, tire and vehicle was made and the motion equation of the vehicle was proposed. Simulation result in same maneuver proved that the presented model gets vehicle dynamic performance by simulation in high precision. The foundation for the research on the vehicle differential lock automatic control system by simulation is laid.
