Problems solved by technology

Many current systems adopt dual-motor coaxial layout and parallel shaft deceleration layout. In order to improve integration and reduce assembly volume, customized disc motors are used, which makes the platform application of the system on different models more difficult. , and the axial and radial dimensions of the entire powertrain are larger, and the overall size is larger. On most models, it can only be placed horizontally, and the layout is more difficult, which cannot meet the needs of longitudinal (rear-wheel drive or four-wheel drive) vehicles. layout requirements

Abstract

The invention provides a hybrid power control system. The system comprises an engine, a first motor and a second motor which are coaxially arranged, wherein a power input shaft of the engine is connected with a first planet row, the first motor is connected with a sun gear of the first planet row, the second motor is connected with a sun gear of a second planet row, the power transmission shaft is used for outputting power from at least one power source of the engine, the first motor and the second motor to the wheels so as to drive the wheels to rotate, and the clutch is arranged between the first planet row and the power transmission shaft and used for transmitting the power from the first planet row to the power transmission shaft in the combined state. The device is ingenious in design and simple and compact in structure, the device composed of the engine, the first motor and the second motor is coaxially arranged, the radial size of the assembly is effectively reduced, meanwhile, when the engine is directly driven, the transmission path is simple, the mechanical loss is small, and the transmission efficiency is high, so that the device has great application potential on most vehicle types with longitudinal arrangement requirements.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a hybrid power device, a control system and an automobile. Background technique [0002] At present, domestic OEMs also have a strong interest in series-parallel systems, and are starting to develop similar products to market. Many current systems adopt dual-motor coaxial layout and parallel shaft deceleration layout. In order to improve integration and reduce assembly volume, customized disc motors are used, which makes the platform application of the system on different models more difficult. , and the axial and radial dimensions of the entire powertrain are larger, and the overall size is larger. On most models, it can only be placed horizontally, and the layout is more difficult, which cannot meet the needs of longitudinal (rear-wheel drive or four-wheel drive) vehicles. layout needs. Contents of the invention [0003] According to one aspect of the present invention,...
