为了解决纯电动轿车模式切换时的操作复杂性和乘坐舒适性等问题,提出了模式识别策略和模式切换策略.模式识别策略是基于模糊控制,通过识别车速、加速度均值和电池SOC(荷电状态)来进行自动识别;模式切换策略是基于德国的冲击度限制标准,通过限制转矩的增加率来减小整车的冲击度.仿真结果表明:提出的控制策略能准确地识别驾驶员的意图,避免了通过手动切换挡位的操作复杂性;并且在模式切换过程中使整车的冲击度小于10m/s3,满足了德国的冲击度限制标准.
In order to solve the operational complexity and ride comfort of pure electric car mode switching, a pattern recognition strategy and a mode switching strategy are proposed.Face recognition strategy is based on fuzzy control, through the recognition of vehicle speed, acceleration average and battery SOC ) Mode switching strategy is based on the German limit of impact standard, by limiting the rate of increase of torque to reduce the impact of the vehicle. Simulation results show that: the proposed control strategy can accurately identify the driver’s intentions , To avoid the manual operation by switching the gear complexity; and in the mode switching process so that the impact of the vehicle less than 10m / s3, to meet the German impact limit.
