Abstract

The invention belongs to the technical field of hybrid power, and relates to a hybrid power drive system and a hybrid electric vehicle. The hybrid power drive system comprises an engine, an input element, an output element, a box body, a first motor, a second motor, a first planet gear set, a second planet gear set, a third planet gear set, a first clutch, a second clutch, a first brake and a second brake. According to the hybrid power drive system, a basic three-planet-gear-set planet gear structure is provided through a reasonable layout of a planet gear set mechanical structure and a plurality of control elements including the first clutch, the second clutch, the first brake and the second brake, and three kinds of E-CVT operating modes can be achieved to obtain higher transmission efficiency. More operating modes may be achieved by selectively connecting one or more of the first clutch, the second clutch, the first brake and the second brake, and higher transmission efficiency is further obtained.

Description

technical field [0001] The invention belongs to the technical field of hybrid power, and in particular relates to a hybrid power driving system and a hybrid power vehicle. Background technique [0002] At present, the drive system of hybrid electric vehicles (including plug-in hybrid electric vehicles, PHEV) mainly includes three basic forms: series, parallel and hybrid (power split type). In the series mode, there is no mechanical connection between the engine and the output shaft, which can realize the optimal control of the speed / torque, but all its energy needs to be transferred to the output shaft after two conversions between mechanical power and electric power, and the loss is relatively large . Parallel transmission has high efficiency, but the mechanical connection between the engine and the output shaft cannot ensure that the engine is always in a better working area, and it is usually used for medium and high speeds. The hybrid combination combines the advantage...
