The invention discloses a switch block and a control method for controlling grading variable voltage charging of an ESASRE suspension. The switch block comprises multiple serially connected controllable small storage battery pack modules, each controllable small storage battery pack module is formed by connecting a small partitioning storage battery pack and a first controllable switch, which are connected in series, with a second controllable switch in parallel; multiple serially connected controllable small storage battery pack modules are connected between two points A and C at the output end of a three-phase rectifier of an energy feeding motor of the ESASRE suspension; a point B is arranged between the points A and C; the voltage sum of all serially connected storage batteries between the points A and B is equal to the voltage sum of all serially connected storage batteries between the points B and C; a third controllable switch is serially connected between the cathode end of one storage battery pack next to the point B and the point C; a fourth controllable switch is serially connected between the points A and B; the respective control over the charging voltage of the storage batteries by the energy feeding motor is realized under the condition of the controllable switches as few as possible.
Description
technical field [0001] The invention belongs to the technical field of vehicle suspension control, and in particular relates to a switch group and a control method for the step-by-step variable voltage charging control of a vehicle electromagnetic energy-feeding type semi-active suspension (ESASRE). Background technique [0002] As an important structural and functional part of a vehicle, the suspension has a great influence on the overall performance of the vehicle. The traditional vehicle suspension cannot recycle the vibration energy between the axle and the sprung mass when the car is running, so that most of the above vibration energy is dissipated in the form of heat energy, resulting in energy waste. With the rapid development of electronic control technology in the automotive industry, energy-feeding suspensions that can realize the function of vibration reduction and convert the vibration energy between the axle and the sprung mass into recyclable energy have attrac...
