Abstract

The invention relates to the technical field of commercial vehicles, in particular to a cab suspension system, a control method of the cab suspension system and a commercial vehicle. The cab suspension system provided by the present invention includes a three-way acceleration sensor, an air spring and a driving controller. The three-way acceleration sensor is used to detect the acceleration of the cab; the damping of the air spring is adjustable, and the air spring is installed on the chassis and Located under the driver's cab; the driving controller is connected in communication with the three-way acceleration sensor and the air spring, and the driving controller is configured to control and adjust the damping of the air spring according to the detection results of the three-way acceleration sensor. The cab suspension system judges the jitter situation through the three-way acceleration sensor, and then adjusts the damping force of the air spring through the driving controller to solve the driving jitter problem and improve driving comfort and safety.

Description

technical field [0001] The invention relates to the technical field of commercial vehicles, in particular to a cab suspension system, a control method of the cab suspension system and a commercial vehicle. Background technique [0002] With the development of the domestic economy and the maturity of the road freight market, the requirements for the reliability, safety, intelligence and comfort of commercial vehicles are getting higher and higher. At present, the cabs of domestic high-end commercial vehicles all adopt the four-point suspension type, that is, air springs are used at the connection between the cab and the frame to ensure comfort and safety. However, with the use of users and the different road conditions of commercial vehicles, it is inevitable that some vehicles will vibrate in the cab when driving on flat roads, which not only makes the driver feel uncomfortable and tired, but also greatly affects driving safety. Can adversely affect the cargo being loaded. ...
