Embodiment Construction

[0023] Exemplary embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present invention, but are not intended to exhaust all possible ways of the present invention, nor are they intended to limit the scope of the present invention. In the present invention, "transmission coupling" means that the driving force / torque can be transmitted between two components. If there is no special description, it means that the two components are directly connected or the driving force / torque is transmitted through a traditional gear pair. .

Abstract

The invention provides a three-motor power split hybrid power system, and belongs to the field of hybrid power vehicles. The power split hybrid power system comprises an engine and three motors. Wherein the engine and the first motor form a power split hybrid power system through a planetary gear mechanism, and the second motor and the third motor form a high-low speed two-gear electric driving system. Therefore, when the vehicle comprising the power split hybrid power system is at a high speed, through high-speed two-power hybrid driving of the high-gear motor electric driving system and the power split hybrid power system of the engine, the engine and the first motor are in an economical power split hybrid power state when the vehicle is in a relatively high speed. Therefore, compared with a high-speed single-mode input type power split hybrid power system in the prior art, the high-speed single-mode input type power split hybrid power system has the advantage that the defects of poor working efficiency and poor fuel consumption of the whole power split hybrid power system when the vehicle is at a high speed can be eliminated.

Description

【Technical field】 [0001] The invention belongs to the field of hybrid power vehicles, and more specifically relates to a hybrid power system with power splitting of three motors and a hybrid power vehicle including the hybrid power system. 【Background technique】 [0002] A hybrid electric vehicle refers to a hybrid electric vehicle in which two or more energy converters provide driving power. The development of power battery technology plays a key role in the power drive system of hybrid electric vehicles and the application of electric drive and engine drive dual power drive devices. [0003] In the prior art, there are various hybrid power systems for vehicles with a power split function, which can realize the decoupling between the speed and torque of the vehicle and the speed and torque of the engine. This type of hybrid system typically includes Toyota's Prius first-generation single-mode input power-split hybrid system, figure 1 A schematic diagram of the power-split...
