Problems solved by technology

For example, a ball screw type shock absorber involved in the Chinese published patent "Ball screw type inerter with mechanical variable inertia coefficient" with application number 201410650452.4 mainly uses a mechanical structure to slow down the instantaneous impact of the road surface , but once processed and manufactured, its various parameters have been determined, and the parameters cannot be adjusted according to different road conditions and different models, and there are certain limitations
The Chinese invention patent with the publication number CN 102261417B "Adjunct air chamber and working method of constant internal pressure air spring with continuously changing volume" discloses an additional air chamber and working method of constant internal pressure air spring with continuously changing volume. The partition is divided into three air chambers, and a linear motor is used to control the movement of the partition, so that the volume of the three chambers of the air spring cylinder body changes, thereby controlling the stiffness of the suspension system, but this method only It can control the stiffness of the suspension system without solving the energy consumption problem

Abstract

The invention discloses a control system of an integrated self-energized active suspension actuator. The control system comprises an active control system and an energy recovery system, wherein the active control system comprises an actuator, a vehicle speed sensor, a road surface unevenness sensor, an unsprung mass displacement sensor, a sprung mass displacement sensor, an actuator speed sensor and a road surface unevenness detector; and the energy recovery system comprises a driver module, a rectification filtration module, a boosting module, a first metal oxide semiconductor (MOS) switch module, a second MOS switch module, an energy storage module, an open circuit voltage (OCV) detection module, a control module and a control circuit power supply module. The control system is applied toa heavy-duty commercial vehicle, integrates an air spring, a spiral spring and a linear motor, can effectively reduce the stiffness of a suspension system, reduces the deviation frequency of the suspension system, can carry out active control, adjusts the damping of the suspension system according to the operating conditions, and improves the smoothness and control stability. In addition, vibration energy recovery can be carried out, and system self-energization is achieved without the need to consume external energy.

Description

technical field [0001] The invention belongs to the technical field of heavy-duty commercial vehicle suspension systems, and in particular relates to an integrated self-powered active suspension actuator control system and a control method thereof. Background technique [0002] When the vehicle is running, affected by the unevenness of the road surface, the sprung mass and the unsprung mass of the vehicle will have relative displacement, causing the vehicle to vibrate. The suspension system is an important part of the automobile chassis that plays a role in damping vibration. Its position is between the frame and the axle. Various forces and moments between bridges affect vehicle ride comfort and handling stability. At present, the power performance of heavy-duty commercial vehicles is getting better and better, and the market has put forward higher requirements for the timeliness of transportation of heavy-duty commercial vehicles. When excited, the vehicle will be subjec...
