The invention provides a multi-axle distributed intelligent driving control method for a vehicle. The multi-axle distributed intelligent driving control method comprises the following steps: step 1, acquiring ballast data of each wheel; 2, judging whether the ballast data is smaller than, larger than or equal to a preset threshold value or not; if yes, judging that the wheel is in a suspended state, and marking the wheel as an invalid wheel; if yes, judging that the wheel is in a grounding state, and marking the wheel as a to-be-determined wheel; step 3, carrying out slip state judgment on the to-be-determined wheel; 4, if the angular acceleration difference value is larger than a preset threshold value, it is judged that the wheel is in a slipping state, and the wheel is marked as an invalid wheel; and fifthly, torque is not distributed to the invalid wheel, and torque is distributed to the effective wheel. The problem that in the prior art, torque of a multi-axle distributed driving vehicle cannot be transferred and controlled when wheels slip or are in a suspended state is effectively solved.
本发明提供一种车用多轴分布式智能驱动控制方法,包括:步骤一:获取各车轮的压载数据;步骤二:判断所述压载数据是否小于、大于或等于预设阈值;如果小于则判断该车轮为悬空状态,并将该车轮标记为无效轮;如果大于或等于则判断该车轮为接地状态,并将该车轮标记为待定轮;步骤三:对所述待定轮进行打滑状态判定;步骤四:如果所述角加速度差值大于预设阈值,那么判断该轮为打滑状态,并标记为无效轮;步骤五:对所述无效轮不分配扭矩,对所述有效轮分配扭矩。本发明有效的解决了在现有技术中多轴分布式驱动车辆在车轮打滑或者悬空状态下扭矩无法转移控制的问题。
