摘要
基于某A级车各总成性能试验数据,利用CarSim建模仿真,并结合整车操作稳定性试验结果验证仿真模型的准确性.依据轮毂电机设计方案,对加装轮毂电机后的汽车进行仿真,分别从开环和闭环的角度评价轮毂电机对汽车瞬态操纵稳定性的影响.结果表明:加装轮毂电机后,汽车瞬态动态响应幅度减弱,响应变迟缓,轨迹跟踪性降低,驾驶负担增加.
Based on the assembly performance test data of an A-class vehicle, the whole vehicle model is built and simulated by CarSim, and the accuracy of the model is verified combining with the handling behavior test results. According to the hub motor design scheme, the vehicle installed with hub motor is simulated, and the effect of hub motor on vehicle transient handling behavior is analyzed by open-loop and closed-loop evaluations. The simulation results show that, after the vehicle is installed with hub motor, the transient dynamical response is weakened, the response is delayed, the tracking ability is decreased, and the driving burden increases.
