Abstract

The invention discloses a hybrid power system for a vehicle, aiming to overcome the problems of complicated power dividing configuration structure and large control difficulty of the existing hybrid power system. The hybrid power system for the vehicle comprises a first hybrid power system for the vehicle and a second hybrid power system for the vehicle. Each of the first hybrid power system for the vehicle and the second hybrid power system for the vehicle comprises a hybrid power system, an engine, a first motor and a second motor, wherein the hybrid power system comprises a planetary gear mechanism and a dual clutch transmission; the output end of an engine crankshaft is fixedly connected with a clutch driving disc in the dual clutch transmission through a connecting shaft; the output and input ends of a first motor rotor are coaxially connected with a planet-row sun gear in the planetary gear mechanism; the output and input ends of a second motor rotor are coaxially connected with a dual clutch transmission first shaft in the dual clutch transmission; and in the second technical scheme, the output and input ends of the second motor rotor are coaxially and fixedly connected with the right end of a dual clutch transmission second shaft in the dual clutch transmission.

Description

technical field [0001] The present invention relates to a power plant for a vehicle, more specifically, the present invention relates to a hybrid power system for a vehicle. Background technique [0002] With the continuous consumption of non-renewable fuels, the gradual warming of the global climate and the intensification of environmental pollution in recent years, auto companies at home and abroad have increased their resource investment in the research and development of new energy vehicles. As pure electric vehicles and fuel cell vehicles are limited by the development of battery technology, the current technology still cannot solve the problems of too short driving range and high battery cost, so hybrid vehicles have a broader application prospect. [0003] Under specific driving conditions, hybrid electric vehicles rely on the motor to supplement and coordinate the required power to achieve a significant reduction in engine fuel consumption. This driving method requi...
