Embodiment Construction

[0021] The hybrid power system of the present invention can realize five working modes: (1) internal combustion engine F idling—power generation working mode; (2) pure electric working mode; (3) internal combustion engine F idling power transmission and electric motor EM2 drive—extended range work (4) Hybrid driving mode of internal combustion engine and electric motor; (5) Driving mode of internal combustion engine.

[0022] (1) The internal combustion engine F is idling—the working state of the vehicle in the power generation mode: ①The vehicle is at rest; ②The clutch is disconnected; the internal combustion engine F is working, driving the generator EM1 to run; ③It can charge the battery pack of the vehicle, or serve as It is used as an emergency generator and outputs 220V voltage for use by other electrical appliances.

[0023] (2) The working state of the vehicle in the pure electric working mode: ①The power of the battery pack is between 15% and 100%; ②The internal combu...

Abstract

The invention provides a hybrid power system in the double clutch form. A motor EM2 drives a vehicle to run in a pure electric working mode. An internal combustion engine F is connected with the motorEM1; and the internal combustion engine F drives the vehicle through a dual clutch DCT in the hybrid power working mode, and can drive the vehicle to run together with the motor EM1 and the motor EM2. Switching between various working modes can be achieved. A DCT gearbox used in the invention has only two-stage variable speed functions, so the synchronizer and the like are not needed. The invention has the characteristics of simple structure and reliability; and the invention can promote the development of the hybrid electric vehicle and has broad market prospect.

Description

technical field [0001] The present application relates to a power system of a hybrid electric vehicle. Background technique [0002] Compared with traditional internal combustion engine vehicles, gasoline-electric hybrid vehicles have the characteristics of low fuel consumption and low pollution; there are many various design schemes for current gasoline-electric hybrid systems, and many design schemes have complex structures and a large number of parts; complex structures lead to Declining reliability, complex maintenance, and rising costs have led to high prices and low reliability of current gasoline-electric hybrid vehicles. Contents of the invention [0003] The invention proposes a hybrid power system with simple structure and high reliability. [0004] Such as figure 1 As shown, the present invention is an oil-electric hybrid power system, the main components are battery pack, internal combustion engine F, motor EM1, motor EM2, dual-clutch DCT, and power output sh...
