The invention discloses a pure electric distributed multi-axle vehicle effective axle detection and power distribution method. The method comprises the steps that 1, a distribution mode is selected according to the vehicle speed; step 2, effective bridge detection; judging whether each round is in a rejecting state or not, if not, entering step 3, and if yes, entering step 4; 3, driving force distribution: in a full-drive mode, uniformly distributing torque required by a driver to all wheels, and in a free distribution mode, selecting the number of drive axles according to the torque required by the driver, and carrying out driving force distribution; and 4, according to a suspended wheel and invalid axle recovery torque limiting algorithm, power is recovered for the invalid axle in a free distribution mode, and power is recovered for the suspended wheel in a full-drive mode.
本发明公开了一种纯电动分布式多轴车辆有效桥检测以及动力分配方法,包括步骤1:根据车速选择分配模式;步骤2:有效桥检测;判断各个轮是否为剔除状态,若不是剔除状态,则进入步骤3,若是剔除状态,则进入步骤4;步骤3:驱动力分配,全驱模式下,将驾驶员需求扭矩平均分配给所有轮,自由分配模式下,根据驾驶员需求扭矩大小、选择驱动桥数量,进行驱动力分配;步骤4:悬空轮及无效桥恢复限扭算法,自由分配模式下,给无效桥恢复动力,全驱模式下,给悬空轮恢复动力。
