Problems solved by technology

[0004] The energy dissipated by vehicle vibration is much greater than the energy dissipated by vehicle braking, but the recoverable vibration energy is more discrete than the recoverable braking energy, and it is not as concentrated as the braking energy, which is the reason for recovery. The energy generated by the vibrations creates a certain degree of difficulty

Abstract

The invention belongs to the technical field of automobile energy conservation, and particularly relates to an automobile vibration energy recovery system and a control method. The automobile vibration energy recovery system is used for recovering energy consumed during vibration in the automobile driving process, and converting mechanical energy produced during vibration into recyclable electric energy. However, energy produced during vibration of an automobile is scattered, and the recovery efficiency is low if the energy is directly recovered into electric energy. By means of the automobile vibration energy recovery system, mechanical energy is firstly converted into pneumatic energy so that scattered energy can be concentrated, and then the pneumatic energy is concentrated and converted into electric energy; through the control over the energy releasing moment of the pneumatic energy, an electric generator can work within a high generating capacity range all the time, and then the energy recovery efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile energy saving, and in particular relates to an automobile vibration energy recovery system and a control method. Background technique [0002] The deterioration of the environment and the shortage of resources have posed severe challenges to the development of the automobile industry. How to better save energy and reduce emissions on the basis of ensuring the original functions of automobiles has become a key issue that needs to be solved urgently. At present, the development of new energy vehicles has solved the problem of vehicle emission reduction from the source, and pure electric vehicles can even achieve zero emissions. Compared with the rapid development of emission reduction technology, there has not been a major breakthrough in the field of automotive energy-saving technology. [0003] During the driving process of the car, frequent braking will consume the kinetic energy of the car, ...
