Abstract

An embodiment of the present application provides a vehicle hybrid powertrain, and the vehicle hybrid powertrain includes a battery, an inverter, a first motor, an engine, a second motor and a gearbox. In this application, two motors are combined with the engine without combining the motors into the existing engine gearbox, and the structure is simple and the transmission efficiency is high. Moreover, when the vehicle is running at a low speed, the engine can be used to drive the vehicle to provide a larger torque for the vehicle to avoid overheating of the motor. When the engine and the motor work at the same time, the engine can drive the first motor to generate electricity, and then charge the battery while the vehicle is running, increasing the cruising range of the vehicle. The rear drive shaft and the two output shafts in the present application can make the vehicle in the front-drive or four-wheel drive state, and the vehicle can be adjusted to the front-drive mode or the four-wheel drive mode according to needs during driving to meet different driving needs.

Description

technical field [0001] The present application relates to the field of vehicle technology, in particular to a vehicle hybrid powertrain, a control method and a vehicle. Background technique [0002] With the popularization of automobiles, the pollution caused by automobiles has attracted widespread attention. In order to reduce the pollution caused by automobiles, new energy vehicles have developed rapidly in recent years. Among them, hybrid vehicles have gradually increased their market share due to their lower carbon emissions and higher cruising range. The transmission system of a hybrid vehicle is different from traditional fuel vehicles and pure electric vehicles. In the current related technologies, the motor is directly combined with a hydraulic automatic transmission (AT), a mechanical continuously variable automatic transmission (CVT) or an electronically controlled mechanical transmission. in an automatic transmission (AMT) gearbox. [0003] In the process of imp...
