Hybrid driving system and vehicle including same

Abstract

The invention relates to a hybrid driving system, which comprises an internal-combustion engine, a first motor, a second motor, a power output shaft used for outputting power, a first brake, a second brake, a first transmission mechanism, and a second transmission mechanism. Two connected transmission mechanisms and brakes are arranged in the hybrid driving system. When the two brakes respectively brake, the two transmission mechanisms are in two different connection modes, namely two different transmission ratios (tap positions) are formed, therefore various working modes and corresponding tap positions can be selected according to different driving conditions of a vehicle, and driving requirements of the vehicle under different working conditions can be met further. Besides, by the adoption of the hybrid driving system provided by the invention, the low-speed torsion of the whole vehicle can be increased and the starting is quickened, moreover, the highest efficiency of the internal-combustion engine can be exerted under a high-speed condition, thereby promoting energy conversion efficiency, reducing tail gas emission and energy loss, and finally achieving the effects of low emission, low fuel consumption and high kinetic energy of the whole vehicle.

AI Technical Summary

Benefits of technology

This patented technology allows for flexible selection between multiple operating states based on factors like speed or road condition. It also increases the amount of work done by an electric car compared to traditional cars without this feature. Additionally, there's no harmful emission from conventional vehicles that use fossil fuels due to their higher specific gravity than gasoline. Overall, these technical improvements lead to improved performance and reduced environmental impact during operation.

Problems solved by technology

This patented technical solution describes how conventional passenger cars use hydraulic systems like hydroplanes without any greenhouse gas emissions. To address these issues, there was developed a new type called hybrid electrified drivetrain (HEC). These solutions involve replacing certain parts of the existing diesel engines with electric motors instead of fossil fuel sources, reducing pollution levels associated with exhaust emission from them. Additionally, they aim to provide more flexibility during acceleration/decelerating modes than just allowing the electric machine to operate efficiently within specific operating environments.
