Problems solved by technology

[0004] At present, the hybrid power system of commercial vehicles and other vehicles is mainly based on the range-extended power system. For commercial vehicles that mainly operate in urban conditions, the energy consumption saving rate of the extended-range power system is relatively obvious, but for those that are often used in suburban conditions and high-speed For highway commercial vehicles running under working conditions, the energy saving rate is not obvious

Abstract

The invention provides a hybrid power driving system and a vehicle. The hybrid power driving system comprises a power battery device, a range extender system and a motor driving system; the power battery device is arranged for supplying electricity to the motor driving system; the range extender system comprises an engine and an electric generator; the electric generator can generate electricity under driving of the engine so as to supply the electricity to the motor driving system and / or charge the power battery device; the hybrid power driving system further comprises a vehicle controller which is arranged for controlling the engine and / or the electric generator of the range extender system to generate driving force; and the range extender system is in mechanical connection with a main coupling mechanism, so that the generated driving force is transmitted to a main driving shaft of the vehicle through the main coupling mechanism so as to drive wheels on the two sides of the driving shaft to rotate. The vehicle controller of the hybrid power driving system can control the engine and / or the electric generator of the range extender system to generate the driving force aiming at different application work conditions, and thus the economy of the vehicle can be effectively improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a hybrid drive system and a vehicle. Background technique [0002] With the increasingly severe energy crisis and global warming, how to realize the energy saving and emission reduction of automobiles has become an urgent task faced by the global automobile industry. Compared with the traditional automobile industry, new energy vehicles represented by hybrid vehicles, new energy vehicles and fuel cell vehicles have obvious advantages in terms of total energy conversion efficiency and total emissions, so they are considered to be an important direction for future automotive development . [0003] At this stage, new energy vehicles mainly include pure electric vehicles and hybrid vehicles. Among them, hybrid power is an important transition technology for the development of new energy vehicles. It has the characteristics of giving full play to the respective advantages of electr...
