Problems solved by technology
Although this kind of suspension control system can improve the stability and comfort of the suspension system, the electronic components in the suspension control system are easily restricted by the installation position in the actual application process, making the control accuracy not accurate enough and installation and maintenance inconvenient ; In addition, the circuit layout of electronic components is easily limited by the space of the suspension system itself, and the cost of the suspension control system is relatively high, so that the suspension control system has not been widely used

The invention discloses a method and a system for regulating a height and damping force. The method comprises the following steps of: arranging a pneumatic valve, an air spring, an adjustable damper and a damping force regulation device used for regulating the damping force of the adjustable damper between a first connection part and a second connection part, wherein the positions of the pneumaticvalve, the air spring, the adjustable damper and the damping force regulation device are adaptive; independently connecting the pneumatic valve with the damping force regulation device and the air spring; colleting at least one movement variable, which is relative to the second connection part, of the first connection part by the pneumatic valve; meanwhile, according to a collected kinematic variable and / or the change of the kinematic variable, controlling the air spring to inflate or deflate by the pneumatic valve to realize height regulation; and / or carrying out air driving on the dampingforce regulation device to control the adjustable damper to output corresponding damping force so as to realize the regulation of the damping force of the adjustable damper. By use of the method, thesensitivity of height regulation and damping force regulation is improved.
Description
technical field [0001] The invention relates to the field of shock absorbers, in particular to a method and system for adjusting height and damping force. Background technique [0002] The existing suspension system mainly includes two control systems of height adjustment and damping force adjustment. These two control systems are independent of each other and have corresponding control mechanisms respectively. In the manual adjustment mode, it is necessary to press two buttons at the same time to realize the synchronous adjustment of the two control systems, which is inconvenient to operate. In the electronic control mode, the suspension control system based on CDC damper (CDC, Continuous Damping Control) is more commonly used. The suspension control system first uses sensors to collect information and sends the collected information to the electronic control unit. The electronic control unit calculates the air pressure in the air spring airbag and the damping force of the...
