The invention discloses a four-wheel-drive hybrid power system and a multi-driving-mode control method, and the system comprises a driving mode selection module which is used for a driver to select a driving mode of a vehicle; an operation parameter acquisition module, used for determining the vehicle demand power P, the power battery charge state SOC and the vehicle speed V; a working mode selection module, used for comparing the three control parameter signals and the conditions of entering and exiting four-wheel drive to judge the optimal working mode in all corresponding working modes under the driving mode; and an output execution module, used for executing power output according to the optimal working mode after receiving a working mode signal of the output execution module. According to the method, the corresponding switching strategy and the working mode with the optimal performance can be automatically operated according to the driving mode selected by the user, and the requirements for the dynamic property and the control stability of the vehicle are met while energy consumption is reduced.

    本发明公开了一种四驱混合动力系统和多驾驶模式控制方法,包括驾驶模式选取模块,供驾驶员选取车辆的驾驶模式;运行参数获取模块,确定车辆需求功率P、动力电池荷电状态SOC和车速V;工作模式选取模块,比较三个控制参数信号和进入退出四驱的条件判断该驾驶模式下对应的所有工作模式中最优的工作模式;输出执行模块,接收输出执行模块的一个工作模式信号后,依据该最优的工作模式执行输出动力。本发明能够根据用户选择的驾驶模式自动运行对应的切换策略和性能最优的工作模式,在降低能量消耗的同时满足车辆动力性和操控稳定性要求。
