Hybrid drive device, drive method and hybrid car

Abstract

The invention provides a hybrid drive device, which is connected with wheels. The hybrid drive device comprises a double planetary row of a planetary frame, an engine, a first motor, a second motor, a differential mechanism, a first clutch and a second clutch wherein a sun wheel of a front planetary raw, a planetary wheel of the front planetary raw, an outer gear ring of the front planetary raw, the sun wheel of the rear planetary raw, the planetary wheel of the rear planetary raw, the outer gear ring of the front planetary raw, the front planetary raw and the rear planetary raw share the double planetary row of a planetary frame; and the planetary wheel of the rear planetary raw is meshed with the planetary wheel of the front planetary raw. The invention further provides a hybrid car which comprises the hybrid drive device, and a drive method of the hybrid drive device. Adopting the technical scheme of the invention, the problem that the oil consumption of the car during the running process is high due to unreasonably distributed power for the generator, the engine and the motor of the series-parallel hybrid system brought by the condition that the optimal output power of the engine can be adjusted by a manner that the generator works around zero rotation speed when the speed needed by the car is higher is solved.

Description

Technical field [0001] The present invention relates to a driving device of a vehicle, an automobile including the driving device, and a driving method, and more particularly to a hybrid power driving device, a driving method of the driving device, and a hybrid automobile including the driving device. Background technique [0002] Generally speaking, hybrid power generally refers to hybrid power, that is, a mixture of fuel (gasoline, diesel, etc.) and electric energy. Hybrid Electrical Vehicle (Hybrid Electrical Vehicle, HEV for short) is an auxiliary power-driven vehicle with an electric motor as the engine. The hybrid drive system has three connection modes: series, parallel and hybrid. The series hybrid power system generally directly drives the generator to generate electricity by the engine, and the generated electric energy is stored in the storage battery, and then transferred from the storage battery to the motor to convert into kinetic energy, and finally the car is dri...

Problems solved by technology

[0013] The purpose of the present invention is to propose a new hybrid driving device and driving method, which can improve the optimal output power of the engine when the speed demanded by the vehicle is relatively high, and the generator needs to work at zero speed to adjust the optimal output power of the engine. The unreasonable power distribution of the generator, engine and electric motor in the hybrid power system causes the problem of high fuel consumption during the running of the vehicle
