Description
Technical Field
The application relates to the technical field of hybrid electric vehicles, in particular to a double-motor hybrid power transmission system and a hybrid electric vehicle.
Background
A hybrid vehicle is a vehicle using various energy sources, and is generally provided with a conventional engine (ICE) using liquid fuel and an electric motor using electric energy. Hybrid vehicles may operate in a variety of drive modes, however, have limited battery capacity and rely primarily on engine combustion to provide power. The dual-motor P1+ P3 hybrid is one of the mainstream schemes of the hybrid power structure at the present stage, such as the THS system for power splitting in some existing vehicle models. Prior art hybrid powertrain systems typically include: the transmission consists of two rows of planetary mechanisms, a generator, a driving motor, an output shaft, a differential and other main components. The generator and the engine are respectively arranged on the sun gear and the planet carrier of the planet row to realize power division, and the driving motor and the other planet mechanism realize speed ratio amplification. The hybrid power system can perform engine power splitting and drive the motor independently. The hybrid scheme has a fixed speed ratio except electric driving, and the engine and the generator form an electronic stepless speed change, so that the engine can be driven at a fixed point and high efficiency, the working efficiency is improved, and the oil consumption of the vehicle is good. However, because the pure power split scheme is adopted in the scheme, the engine can only output power in a power split mode without torque amplification, so that the power output cannot be amplified, and the power acceleration of the vehicle is influenced. When the vehicle runs at high speed, part of the power of the engine must be diverted to the driving motor or the battery through the generator, so that additional energy loss is generated, and the fuel consumption of the vehicle is deteriorated.
