Abstract

The invention discloses an improved ceiling control method of an energy feedback suspension system, and belongs to the field of automobile energy conservation and emission reduction. An energy feedback suspension is formed by connecting a spring and a linear motor in parallel, and an improved ceiling control strategy is put forward with the control aim of low suspension energy consumption and excellent riding comfort. The working mode of the linear motor is analyzed and judged by connecting an automobile signal, and the suspension is in three different damping modes; meanwhile, when the suspension is in a driven mode and a semi-driving mode, the energy feedback suspension system can recycle vibration energy through an energy feedback circuit, so the aims of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention belongs to the field of automobile energy saving and emission reduction, and in particular relates to an improved ceiling control method for an energy-feeding suspension system. Background technique [0002] The traditional passive suspension dissipates all the vibration energy of the suspension in the form of heat energy, and because its fixed structural parameters cannot adapt to changing road conditions, its application on vehicles is limited. Compared with passive suspension, the vibration isolation of semi-active suspension has been greatly improved, but its scope of application is limited. Active suspension actively adapts to road conditions and improves vehicle dynamics by providing appropriate driving force, but it requires a large amount of external energy to provide driving force and increases vehicle fuel consumption, so it has not been widely used. In recent years, many scholars have begun to focus on electromagnetic suspensi...
