The embodiment of the invention provides a torque distribution method and system and a vehicle, and the method comprises the steps: obtaining the current remaining electric quantity of a power battery of the vehicle and the demand torque of the vehicle under the condition that the current driving mode of the vehicle is a preset driving mode; determining a target electric quantity interval in which the current residual electric quantity is located from a plurality of preset electric quantity intervals; and according to the distribution proportion corresponding to the target electric quantity interval, the engine and/or the motor are/is controlled to output the torque of the corresponding proportion. According to the embodiment of the invention, under the preset driving mode, the demand torque of the vehicle is distributed to the engine and/or the motor according to the current residual electric quantity of the vehicle and the corresponding distribution proportion, so that reasonable distribution of the torque can be realized, and the cruising ability of the vehicle is further improved.

    本申请实施例提供了一种扭矩分配的方法、系统以及车辆,所述方法包括:在车辆当前的驾驶模式为预设驾驶模式的情况下,获取所述车辆的动力电池的当前剩余电量和所述车辆的需求扭矩;从多个预设电量区间中,确定所述当前剩余电量所处的目标电量区间;按照所述目标电量区间对应的分配比例,控制所述发动机和/或所述电机输出各自对应比例的扭矩。本申请实施例通过在预设驾驶模式下,根据车辆当前的剩余电量并按照对应的分配比例来分配车辆的需求扭矩给发动机和/或电机,可以实现扭矩的合理分配,从而进一步提高车辆的续航能力。
