Electric vehicle anti-settling composite energy-feeding suspension actuator and its control method

Abstract

The invention discloses an electric vehicle anti-settling compound energy-feeding suspension actuator and a control method thereof. The suspension actuator includes a magneto-rheological shock absorber, a motor unit, an energy-feeding unit and an actuator monitoring The control method of the device comprises the steps of: 1. data collection and transmission; 2. the actuator controller controls the suspension actuator in four modes: high energy-saving mode, energy-saving mode, stable mode and dynamic mode according to the sampled data. control. The invention is reasonable in design and easy to realize, and can adjust the height of the sprung mass part and the unsprung mass part of the automobile, as well as the control force of the actuator. The size of the suspension system can be multi-mode switched to improve the comfort and stability of the car. At the same time, the energy generated by the suspension system can be recovered in time to reduce the waste of vehicle energy and improve the mileage and battery life of electric vehicles. Strong practicality.

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...

However, the energy recovery system is single, and there is no deep recovery of the vibration energy of the suspension system

In 2017, Zhao Hongxing and other scholars designed a combination of piezoelectric ceramic spherical shell and permanent magnet linear motor to form a vibration energy composite recovery device. However, this method only realizes energy recovery and fails to fully consider electric vehicles. Driving road conditions, switch suspension system mode
