The invention relates to a plug-in type hybrid power system based on a four wheel drive sport utility vehicle, and belongs to the technical field of hybrid power vehicles. The hybrid power system includes a whole vehicle control device, a motor control device, a motor, a speed changer control device, an automatic speed changer, a battery management system, a power battery, a motor control device,a motor, a speed changer clutch, a motor end electromagnetic clutch, a direct current-direct current converter, a vehicle-mounted battery charger, a preceding stage main speed reducer, and a posteriorstage main speed reducer. The output end of the motor is connected with a middle speed reducer through the automatic speed changer. The middle speed reducer is separately connected to the preceding stage main speed reducer and the posterior stage main speed reducer. The preceding stage main speed reducer is connected with a front axle in a coupled mode. The posterior stage main speed reducer is connected with a back axle in a coupled mode. The output end of the motor is connected with the posterior stage main speed reducer. According to the hybrid power system, low speed accelerating assistance can be achieved, the overtaking accelerating capacity is improved, driving requirements of a driver can be met, and the driving safety and reliability are ensured.
Description
