The invention provides a four-wheel-drive hybrid power system, a control method and a vehicle, and the four-wheel-drive hybrid power system comprises an engine, a first motor, a second motor, a third motor, a first transmission part, a second transmission part and a third transmission part, the second transmission part comprises a second transmission shaft and a first driven gear arranged on the second transmission shaft; the third transmission part is arranged on the side, away from the first transmission part, of the second transmission part; a fourth transmission part; the engine, the first motor, the second motor, the first transmission part, the second transmission part and the third transmission part form a front axle driving system, and the third motor and the fourth transmission part form a rear axle driving system. The four-wheel-drive hybrid power system is divided into the front-axle drive system and the rear-axle drive system, so that when the vehicle only has the two-wheel-drive requirement, the front-axle hybrid power system provides driving force, the rear-axle pure electric drive system is decoupled from the rear wheel end, and the economical efficiency of the vehicle can be considered while the dynamic property and cross-country ability of the vehicle are guaranteed.
本发明提供了一种四驱混合动力系统、控制方法及车辆,四驱混合动力系统包括发动机、第一电机、第二电机、第三电机,还包括:第一传动部;第二传动部,第二传动部包括第二传动轴和设置于第二传动轴上的第一从动齿轮;第三传动部,第三传动部设置于第二传动部远离第一传动部的一侧;第四传动部;发动机、第一电机、第二电机、第一传动部、第二传动部和第三传动部构成前轴驱动系统,第三电机和第四传动部构成后轴驱动系统。通过将四驱混合动力系统分为前轴驱动系统和后轴驱动系统,使得车辆仅有两驱需求时,由前轴混动系统提供驱动力,后轴纯电驱动系统与后车轮端解耦,可在保证车辆动力性与越野性的同时,兼顾车辆经济性。
