Abstract

The invention provides a novel four-drive hybrid power system and further provides a novel four-drive hybrid power driving method. The novel four-drive hybrid power system comprises an engine, an automatic transmission, a first motor, a battery, a first power battery, a second power battery, a second motor and a reducer. The engine is connected with a front driving shaft of a vehicle through the automatic transmission to drive front wheels of the vehicle; the engine is connected with the first motor; the first motor is connected with the first power battery; the first power battery is connected with the second power battery; the second power battery is connected with the second motor; the battery is connected with the first power battery and used for meeting the requirements of electric appliances for a voltage platform of the vehicle; and the second motor is connected with a rear driving shaft of the vehicle through the reducer to drive rear wheels of the vehicle. The four-drive function can be achieved, and front and rear power assemblies can output torque as required, so that the vehicle obtains the optimal power combination, the dynamic property of the vehicle is remarkably improved, meanwhile, the economical efficiency is excellent, and energy saving and environmental protection are achieved.

Description

technical field

[0001] The present application relates to the field of automobile power systems, in particular to a novel four-wheel-drive hybrid power system and a driving method thereof. Background technique

[0002] Automobiles have been widely used as a means of transportation. In order to meet the requirements of energy saving and environmental protection, new energy vehicles have become the main direction of the development of the vehicle industry. In the driving system of new energy vehicles, the hybrid system has attracted wide attention because it has the advantages of low emission of electric vehicles and high specific energy of internal combustion locomotives.

[0003] The hybrid power system in the prior art is mainly divided into P0, P1, P2, P3, P4, and PS (planetary row scheme) systems according to the location of the motor. Among them, the P0 system means that the motor is installed at the front of the engine. This type of hybrid is called the P0 architecture...
