Abstract

The invention discloses a hybrid electric vehicle power control system and a hybrid electric vehicle. The hybrid electric vehicle power control system comprises an internal combustion engine, a singleclutch, a driving motor assembly, a dual-clutch gearbox assembly, a driving shaft and a single clutch hydraulic control mechanism; the single clutch hydraulic control mechanism comprises an oil pumpand a single clutch hydraulic control valve assembly; the single clutch hydraulic control valve assembly comprises a main oil circuit pressure adjustment valve, a first solenoid valve and a second solenoid valve; the oil pump is sequentially connected with the first solenoid valve and the main oil circuit pressure adjustment valve through pipelines to form a first one-way passage; and the oil pumpis connected with the second solenoid valve through a pipeline to form a second one-way passage. The hybrid electric vehicle power control system can conveniently control the single clutch to be connected or disconnected by controlling the magnitude of the pressure in the second one-way passage, and thus conversion of different driving modes of the hybrid electric vehicle is achieved.

Description

technical field [0001] The invention relates to the field of hybrid electric vehicle power, and more particularly, relates to a hybrid electric vehicle power control system and a hybrid electric vehicle. Background technique [0002] Hybrid vehicles generally refer to gasoline-electric hybrid vehicles, that is, vehicles that use traditional internal combustion engines (diesel engines or gasoline engines) and electric motors as power sources. With the increasingly stringent environmental protection measures around the world, hybrid vehicles have become the focus of automobile research and development because of their energy-saving and low-emission characteristics. [0003] The power control system of the existing hybrid electric vehicle is relatively complicated, which leads to high cost and difficult maintenance of the hybrid electric vehicle. [0004] Therefore, how to provide a power control system that has a simple structure and can conveniently control the driving mode ...
