The invention provides a torque distribution method, a hybrid power system and a vehicle. The method comprises the following steps: acquiring required torque; in the range that the torque provided by the engine is smaller than the required torque, multiple fuel-saving engine torques are selected, the fuel-saving amount under multiple unit electric quantities is calculated, and the fuel-saving amount under the target unit electric quantity is selected from the fuel-saving amount; a plurality of charging engine torques are selected within the range that the torque provided by the engine is larger than or equal to the required torque, the fuel quantity required by a plurality of unit electric quantities is calculated, and the fuel quantity required by the target unit electric quantity is selected from the fuel quantity; whether the fuel saving amount under the target unit electric quantity is smaller than the fuel amount needed by the target unit electric quantity or not is judged, and if yes, the engine distribution torque and the motor distribution torque are obtained based on the fuel saving amount under the target unit electric quantity; if not, the engine distribution torque and the motor distribution torque are obtained based on the fuel quantity needed by the target unit electric quantity. According to the technical scheme, efficient torque distribution is achieved, and efficient operation of the system is guaranteed.
本申请提供一种扭矩分配方法、混动系统及车辆。该方法包括:获取需求扭矩;在发动机提供的扭矩小于需求扭矩的范围内,选取多个节油发动机扭矩,计算多个单位电量下的节油量并从中选择目标单位电量下的节油量;在发动机提供的扭矩大于等于需求扭矩的范围内选取多个充电发动机扭矩,计算多个单位电量所需的燃油量并从中选择目标单位电量所需的燃油量;判断目标单位电量下的节油量是否小于目标单位电量所需的燃油量,如是:基于目标单位电量下的节油量得到发动机分配扭矩和电机分配扭矩;如否:基于目标单位电量所需的燃油量得到发动机分配扭矩和电机分配扭矩。根据本申请的技术方案,实现了扭矩高效分配,保证了系统高效运行。
