Problems solved by technology

[0003] With the development of technology, higher requirements are put forward for the fuel efficiency, exhaust emission, power performance, space compactness and cost of hybrid vehicles. In order to solve the above problems, some hybrid power transmission systems have appeared one after another, but these systems cannot Nice to solve all the above problems
[0004] For example, the hybrid drive technology with dual planetary arrays and dual motors has been adopted. Although it has greatly improved exhaust emissions and power performance, it still has disadvantages such as high cost, complicated control, and insufficient reliability.
[0005] For example, the hybrid drive technology using traditional dual-clutch transmission and motor integration, although the technical difficulty is relatively small, and fuel efficiency has been improved to a certain extent, but there are disadvantages such as large space occupation, little emission improvement, and high cost.

Embodiment Construction

[0043] see figure 1, the driving system 100 of the hybrid vehicle of the present invention includes: an engine 1 , a generator 3 and an electric motor 12 , and the driving system 100 is configured with a hybrid driving mode. Wherein, the hybrid driving mode mainly includes a first hybrid driving mode, a second hybrid driving mode, a third hybrid driving mode and a fourth hybrid driving mode. When the driving system 100 is executing the first hybrid driving mode, the hybrid vehicle can be simultaneously driven by the electric motor 12 , the engine 1 and the generator 3 . When the driving system 100 is executing the second hybrid driving mode, the electric motor 12 and the engine 1 can jointly drive the hybrid vehicle. When the driving system 100 is executing the third hybrid driving mode, the hybrid vehicle can be jointly driven by the electric motor 12 and the generator 3 . When the driving system 100 is executing the fourth hybrid driving mode, the hybrid vehicle is jointly...

Abstract

The invention provides a driving system for a hybrid vehicle and the hybrid vehicle. The driving system comprises an engine, a generator and a motor, wherein the driving system is provided with hybriddrive modes comprising a first hybrid drive mode, a second hybrid drive mode, a third hybrid drive mode and a fourth hybrid drive mode. According to the driving system disclosed by the invention, through the arrangement of the hybrid drive modes, the driving modes of the driving system are diversified, a driver can realize multiple driving modes conforming to actual conditions according to different roads and use conditions, the transmission efficiency is improved, and the energy consumption is saved. The motor, the engine and the generator can jointly participate in driving in the first hybrid drive mode of the driving system, so that the acceleration performance of the driving system is effectively improved.

Description

technical field [0001] The invention relates to the technical field of hybrid vehicle manufacturing, in particular to a drive system of a hybrid vehicle and a hybrid vehicle with the drive system. Background technique [0002] Due to the immaturity of pure electric drive technology and the obvious shortcomings of traditional transmission systems, hybrid power transmission system technology will become the main application technology of transmission systems at present and in the future. [0003] With the development of technology, higher requirements are put forward for the fuel efficiency, exhaust emission, power performance, space compactness and cost of hybrid vehicles. In order to solve the above problems, some hybrid power transmission systems have appeared one after another, but these systems cannot Nice to all solve the above problems. [0004] For example, the hybrid drive technology with dual planetary arrays and dual motors has been adopted. Although it has greatly...
