Problems solved by technology

[0004] When the hybrid transmission is working, it is necessary to reasonably coordinate the operation mode of the engine and the electric motor according to various driving conditions, not only to provide the vehicle with power, torque and power requirements under various working conditions, but also to switch the electric motor and engine operation mode smoothly when the working conditions change requirements and high-efficiency use of energy, but the existing hybrid transmissions have a large impact when switching between various working conditions, which reduces energy use efficiency and affects driving experience

Abstract

The invention discloses a dual-motor hybrid power gearbox which comprises an engine, a main driving motor, an auxiliary driving motor, a planet row, a parking clutch and an engine lock-up clutch. An outer gear ring of the planet row is connected with a main driving motor and an output shaft through gear meshing, a planet carrier of the planet row is connected with the engine, a sun gear of the planet row is connected with the auxiliary driving motor, the auxiliary driving motor is an ISG motor, an input shaft of the main driving motor is connected with the output shaft through gear meshing, and the output shaft is connected with a differential through gear meshing. A parking clutch is arranged on an outer gear ring of the planet row, and the parking clutch locks the outer gear ring of the planet row to meet the vehicle parking requirement. The engine lock-up clutch is arranged on the planet carrier of the planet row and the engine input shaft, and the engine lock-up clutch locks the planet carrier of the planet row and the engine input shaft to achieve the engine lock-up function. The gearbox has the advantages of being reliable in work, low in energy efficiency, compact in structure and low in cost.

Description

technical field [0001] The invention belongs to the technical field of new energy hybrid power systems, and in particular relates to a double-motor hybrid power transmission and a control method. Background technique [0002] Today, when energy saving and environmental protection have become the development theme of the automobile industry, new energy electric vehicles have become the key research objects of various automobile manufacturers. [0003] There are many types of gearboxes for hybrid electric passenger cars, some of which are bulky due to their low integration, some of which are too expensive to sell, and some of which rely too much on the functions of the motor drive controller. In order to consider the design cost, reliable operation, and light weight at the same time, a dual-motor hybrid transmission is described in this patent; the dual-motor design not only ensures the integrity of the driving and power generation functional requirements of the hybrid transmi...
