Abstract

The present invention discloses a hydraulic interconnection suspension pipeline connection mode switching device and a control method. A sensor unit comprises a vehicle speed sensor and four range finders, and the vehicle speed sensor and the four range finders are responsible for inputting the real-time vehicle speed and the real-time length of four suspensions of a vehicle into an electronic control unit (ECU) respectively; the ECU of a processing unit is used for calculating the real-time data of the vehicle by combining the data stored in an memory unit; and an electromagnetic directional valve A and an electromagnetic directional valve B of an execution unit are used for controlling a hydraulic oil pipeline to be connected and disconnected, and thus switching among different connection modes of the hydraulic interconnection suspensions is realized. By applying the method, the running state of the vehicle can be judged, appropriate hydraulic interconnection suspension pipeline connection modes are thus selected, the vehicle body posture is controlled, and the riding comfort of the vehicle is improved.

Description

Technical field [0001] The invention belongs to the field of automobile suspension control, and particularly relates to a hydraulic interconnected suspension pipeline connection mode switching device and a control method. Background technique [0002] With the popularization of automobiles, people have higher and higher requirements for car comfort. More and more high-end vehicles develop active suspensions, air suspensions and interconnected suspensions with superior performance to meet this requirement. Interconnected suspensions are mainly divided into air interconnected suspensions and hydraulic interconnected suspensions. Among them, hydraulic interconnected suspensions are mainly divided into two types. One is the left and right interconnection, which can effectively reduce the vehicle's roll in a curve; the second is the front and rear interconnection, which can effectively reduce the large nodding and raising of the head when the vehicle is accelerating or decelerating....
