The invention provides a parallel hybrid power torque distribution method, device and equipment and a medium, and relates to the technical field of new energy automobiles. The method comprises the following steps: traversing the distribution torque of an engine under different rotating speeds and different required torques of a motor; in any round of traversal process, if the current distribution torque of the engine is smaller than the current demand torque, a fuel equivalent factor of the motor in a power assisting mode is calculated according to the energy recovery coefficient, and if the current distribution torque is larger than the current demand torque, a fuel equivalent factor of the motor in a charging mode is calculated; the distribution torque of the engine corresponding to the fuel equivalent factor meeting the set condition is selected to serve as the target distribution torque of the engine under the current rotating speed and the current demand torque; establishing a torque distribution table according to respective target distribution torque of the engine and the motor under different rotating speeds and different required torques; and the real-time rotating speed and the real-time required torque of the motor are obtained, and the real-time distribution torque is obtained through the torque distribution table. The energy consumption of the whole vehicle can be reduced.

    本申请提供一种并联式混合动力扭矩分配方法、装置、设备和介质,涉及新能源汽车技术领域。方法包括:在电机的不同转速和不同需求扭矩下,对发动机的分配扭矩进行遍历;在任一轮遍历过程中,若发动机的当前分配扭矩小于当前需求扭矩,则根据能量回收系数计算电机处于助力模式的燃油等价因子,若大于当前需求扭矩,则计算电机处于充电模式的燃油等价因子;选择符合设定条件的燃油等价因子所对应的发动机的分配扭矩,作为当前转速和当前需求扭矩下发动机的目标分配扭矩;根据不同转速和不同需求扭矩下发动机和电机各自的目标分配扭矩建立扭矩分配表;获取电机的实时转速和实时需求扭矩,并通过扭矩分配表获取实时分配扭矩。本申请可以降低整车能耗。
