Description
technical field [0001] The invention belongs to the technical field of vehicle vibration damping devices, and in particular relates to a control method for an energy-feeding type damping continuously adjustable actuator. Background technique [0002] When the vehicle is driving on an uneven road, the vibration energy caused by the bumps of the road, the acceleration and deceleration of the vehicle, and the steering has not been paid attention to and utilized, and it is usually mainly converted into heat dissipation by the vehicle suspension shock absorber. Lose. If these vibration energies can be recovered and utilized, renewable energy will be obtained, which can effectively reduce vehicle energy consumption, thereby achieving the purpose of saving energy. Suspension is one of the important components of a car, and at the same time the suspension plays a very important role in damping vibration. At present, vehicle suspension systems mainly include passive suspension, sem...
