摘要:
为了研究驱动力矩在驱动/转向工况下对汽车操纵稳定性的影响,建立了包含纵向运动﹑侧向运动﹑横摆运动以及前﹑后车轮转动在内的非线性5自由度整车模型.通过理论推导和建模仿真,得出驱动力矩对汽车操纵稳定性的影响来自3个方面:轮胎纵向力在侧向的分量﹑轮胎纵向力对侧偏力的影响和纵向车速的变化.通过对前轮驱动车型进行仿真,结果表明,驱动力矩的增大会使整车转向性能减弱，驱动轮打滑时,汽车失去转向能力.
Abstract:
To analyze the influence of the drive torque on vehicle handling stability in the situation of drivingand steering,a non-iner 5 degree of freedom full vehicle model is established,including the longitudinal mo-tion,the lateral motion,the yaw motion and the rotations of the front and rear wheels.The weight of the tirelongitudinal force in the lateral,the influence of the longitudinal tire force on the corning stiffness and the vari-able longitudinal speeds are the three aspects impact vehicle handling stability by theoretical derivation andsimulation. By simulating the front drive vehicle,the result shows that,the steering performance is gettingworse with the drive torque increasing; even worse,the steering ability will be lost when the drive wheels areshipped.
