Problems solved by technology

[0003] In related technologies, the power system of extended-range electric vehicles mostly adopts the series mode, the engine does not participate in power assistance, and electric vehicles are completely driven by electric motors, and the power performance is poor
In order to improve the power performance of the electric vehicle, it is necessary to increase the power of the drive motor, which will lead to a low load on the drive motor, thus making the work efficiency of the drive motor poor.

Abstract

The invention discloses a control method of a hybrid electric vehicle. A power transmission system of the hybrid electric vehicle comprises a power battery, an engine, a first motor, a second motor, a first planetary gear set, a second planetary gear set, an output shaft, a first clutch and a second clutch. The control method comprises the following steps: detecting the SOC (state of charge) of the power battery, and obtaining the demanded torque of the hybrid electric vehicle; controlling the hybrid electric vehicle to enter a corresponding working mode according to the SOC of the power battery and the demanded torque of the hybrid electric vehicle, wherein the working modes comprise a pure electric driving mode, a pure electric accelerating mode, a hybrid-power accelerating mode, a first range-extended mode, a second range-extended mode and an range-extended accelerating mode. According to the control method, the power property of the hybrid electric vehicle is improved through the assistance of the engine, so that the working efficiency of the motors is improved, and the cost of the motors is reduced. The invention further discloses a hybrid electric vehicle and a power transmission system of the hybrid electric vehicle.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a control method of a hybrid vehicle, a hybrid vehicle implementing the control method and a power transmission system of the hybrid vehicle. Background technique [0002] At present, the short mileage of pure electric vehicles has become the biggest bottleneck in its development, and the range-extended electric vehicles can not only meet the requirements of daily zero-emission driving, but also meet the requirements of longer mileage, so the range-extended electric vehicles will Become a trend in the development of hybrid vehicles. [0003] In related technologies, most of the power systems of extended-range electric vehicles adopt series mode, and the engine does not participate in power assistance. Electric vehicles are completely driven by electric motors, and the power performance is poor. In order to improve the vehicle power performance of the electric vehicle, ...
