The invention discloses an energy recovery and storage circuit of a hybrid suspension of an overall vehicle and a control method of the energy recovery and storage circuit. The energy recovery and storage circuit comprises four main linear motor-storage battery energy feedback circuits of the overall vehicle, six MOS tubes, four diodes, a control unit ECU, two voltage detection units and two storage batteries, wherein the voltage detection units convey voltage signals to the control unit ECU by detecting output end voltage of the four linear motor-storage battery energy feedback circuits and charging end voltage of the two storage batteries respectively, and achieve on / off control of the six MOS tubes through the control unit ECU, so that the four linear motor-storage battery energy feedback circuits concertedly charge the storage batteries in order; and the two storage batteries concertedly work in energy storage and energy supply states. A storage battery-based energy storage circuit is designed on the basis of recovering vibration energy of the hybrid suspension through a super capacitor; and the feedback vibration energy can be stably stored.
Description
technical field [0001] The invention relates to an energy recovery and storage circuit of a hybrid suspension of a whole vehicle and a control method thereof, and belongs to the fields of automobile electronic control technology and automobile energy saving and emission reduction technology. Background technique [0002] With the rapid development of the economy, the number of private cars is gradually increasing. Then it brings problems such as environmental pollution and resource shortage, and the concept of energy saving and emission reduction has also been put on the agenda of many countries. Traditional vehicles use passive suspension to buffer the impact of the ground on the body, but a lot of energy is dissipated in the form of heat energy in the vibration of the passive suspension. The proposal of the new linear motor hybrid suspension allows part of the vibration energy to be recovered. Many scholars have also studied the energy feeding characteristics of the linea...
