Abstract

The invention discloses an anti-settling combined energy-regenerative suspension actuator of an electric automobile and a control method thereof; the suspension actuator comprises a magneto-rheological shock absorber, a motor unit, an energy feedback unit and an actuator monitoring device, and the control method comprises the following steps: 1, data acquisition and transmission; 2, an actuator controller controls the suspension actuator in four modes including a high energy-saving mode, an energy-saving mode, a stable mode and a dynamic mode according to the sampling data of the actuator controller. The suspension actuator is reasonable in design, easy to realize, and the heights of the sprung mass and the unsprung mass of the automobile and the control force of the actuator can be adjusted; when the automobile runs on different road surfaces, multi-mode switching can be carried out on the suspension system according to the magnitude of an energy feedback voltage on a piezoelectric plate, and the comfort and stability during automobile running are improved; meanwhile, energy generated by the suspension system is recycled in time, waste of automobile energy is reduced, the endurance mileage of the electric automobile is prolonged, the service life of a battery is prolonged, and the practical value is high.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle suspension actuators, and in particular relates to an electric vehicle anti-subsidence composite energy-feeding suspension actuator and a control method thereof. Background technique [0002] As the number of automobiles continues to increase, the storage of petroleum energy continues to decrease, and automobile exhaust emissions have exacerbated the deterioration of the natural environment, especially abnormal phenomena such as the global greenhouse effect and smog weather, which have seriously endangered human life and health and social stability. Sustainable development, green and environmentally friendly new energy electric vehicles have become the focus of contemporary society. After the Chinese government formulated a series of subsidy policies for the development of new energy vehicles in 2009, the related technologies of new energy vehicles have developed rapidly, but the shortcom...
