| 摘要： | 一种防止电动汽车的车辆出现“死踏板现象”的扭矩控制方法，包括动力电池单元，其技术要点是，动力电池单元与扭矩控制单元的输入端相连接，所述扭矩控制单元输入端还与加速踏板信号输出单元相连接；所述扭矩控制单元与电机驱动单元相连接；所述电机驱动单元通过由变速箱、传动轴和差速器组成的传动单元与驱动单元的输入端相连接。本发明扭矩控制根据动力系统最大扭矩能力和驾驶员可能出现的最大的扭矩请求，实时修改驾驶扭矩曲线，避免出现驾驶员扭矩请求超出动力系统最大扭矩能力的情况，即“死踏板现象”。所述的扭矩控制方法既能避免“死踏板现象”又能够保证动力系统最大扭矩能力，适用于需要使用动力电池的纯电动车和混合动力电动车。 | ||
| 摘要(英文)： | A vehicle of the electric automobile "dead pedal phenomenon" in the torque control method, including power battery unit, is characterized in that, with a torque power battery unit is connected to the input end of the control unit, the torque control unit also with the accelerator pedal signal input end of the output unit which is connected to; the torque control unit is connected with the motor drive unit; a drive unit of the motor comprises a gear box, the transmission shaft and the differential gear box of the transmission unit is connected with the input end of the driving unit. Torque control of the present invention according the power system the maximum torque capacity and the driver the possibility of the largest torque request, real time modification driving torque curve, to avoid the driver torque request exceeds the power system of the maximum torque capacity, i.e. "dead pedal phenomenon". The torque control method can avoid the "dead pedal phenomenon" power system can also be ensured to the maximum torque capacity, requires the use of a power battery is a pure electric vehicle and hybrid electric vehicle. | ||
