Abstract

The invention discloses a driving system and method for a hybrid power four-wheel drive automobile. The system comprises a battery module, an engine module, a generator and a gearbox, wherein the engine module is connected with the gearbox through the generator; the gearbox drives front wheels of the automobile through a transmission shaft and a drive axle; the driving system for the hybrid power four-wheel drive automobile further comprises an electric motor and a differential; the battery module is electrically connected with the generator and the electric motor respectively; the electric motor is connected with the differential; and the differential drives rear wheels of the automobile. The system collects and converts power of the automobile during breaking and downhill running into electric energy for storage, and the stored electric energy enables the electric motor to work to drive the rear wheels when four-wheel drive is needed, so that energy is saved, and the economical efficiency of the whole automobile is improved. The driving system and method are applicable to the hybrid power four-wheel drive automobile.

Description

technical field [0001] The invention relates to the field of vehicle power control, in particular to a drive system and method for a four-wheel drive vehicle of a hybrid vehicle. Background technique [0002] The four-wheel drive car takes into account the characteristics of cars and off-road vehicles. It has strong road applicability, power and safety, and is loved by consumers. Its main advantages are as follows: [0003] 1) Improve passability. Since all four wheels of a four-wheel drive vehicle transmit power, the driving force obtained by the vehicle is twice that of a two-wheel drive. Moreover, the front and rear wheels support each other, which greatly improves the passability on wet, ice and snow roads and uneven roads. [0004] 2) Improve climbing performance. Four-wheel-drive vehicles can climb steeper slopes that two-wheel-drive vehicles cannot. [0005] 3) Excellent cornering performance. The adhesion of the tire is closely related to the power transmitted t...
