The invention discloses a vehicle and a torque distribution method and device.The vehicle comprises an engine, a first motor and a second motor, and the torque distribution method comprises the following steps that the torque distribution mode and the vehicle demand torque of the vehicle are obtained; acquiring an engine torque distribution factor, a first motor torque distribution factor and a second motor torque distribution factor according to the torque distribution mode of the vehicle and the required torque of the vehicle; and according to the engine torque distribution factor, the first motor torque distribution factor and the second motor torque distribution factor, the engine, the first motor and the second motor are controlled to provide corresponding output torque. Therefore, the engine torque distribution factor, the first motor torque distribution factor and the second motor torque distribution factor are dynamically adjusted according to different torque distribution modes of the vehicle and the vehicle demand torque, so that distribution of the torque distribution factors in multiple torque distribution modes is achieved, the energy consumption of the whole vehicle is reduced, and the driving feeling is improved.
本发明公开了一种车辆及其扭矩分配方法和装置,其中,车辆包括发动机、第一电机和第二电机,方法包括以下步骤:获取车辆的扭矩分配模式和车辆需求扭矩;根据车辆的扭矩分配模式和车辆需求扭矩获取发动机扭矩分配因子、第一电机扭矩分配因子和第二电机扭矩分配因子;根据发动机扭矩分配因子、第一电机扭矩分配因子和第二电机扭矩分配因子,分别控制发动机、第一电机和第二电机提供相应的输出扭矩。由此,根据不同的车辆的扭矩分配模式和车辆需求扭矩,动态调整发动机扭矩分配因子、第一电机扭矩分配因子和第二电机扭矩分配因子,从而实现多种扭矩分配模式下的扭矩分配因子的分配,降低整车能耗,并提升驾乘感受。
