Embodiment Construction

[0038] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0039] see figure 1, the intelligent electronically controlled air suspension system for commercial vehicles shown in the figure mainly includes integrated ECU1, air compressor 2, 4 sets of three-in-one sensors 3, 4 sets of variable stiffness air springs 4, and an air storage tank 8.

[0040] Each three-in-one sensor 3 is composed of a range sensor, an air pressure sensor and a temperature sensor, and is fixed on the air bag upper cover 4a of the variable stiffness air spring 4 in the form of threads (see Figure 5 ), and the overall protection level can reach IP6K9K, 4 sets of three-in-one sensors 3. Connect to the signal input end of the integrated ECU through a CAN16 and waterproof connector.

[0041] The ranging sensor adopts the ultrason...

Abstract

The invention provides an intelligent electronic control air suspension system for a commercial vehicle. The intelligent electronic control air suspension system is composed of an integrated ECU, an air compressor, a three-in-one sensor, a rigidity-variable air spring, an air supply pipeline, a wiring harness, a key, an air storage tank, a pressure sensor and the like. The height, air pressure andtemperature of the air bag are monitored in real time through the three-in-one sensor. By comparing the height of the air bag with the storage height in the system and combining the current vehicle state and road conditions, inflation and deflation of the air bag are controlled to achieve adjustment of various vehicle body heights. Rigidity adjustment of the air bag is achieved through on-off ofa built-in electromagnetic valve of the air bag, the phenomena of side tilting and nodding during turning and braking are avoided, and both vehicle driving comfort and control stability are achieved.The axle load of the vehicle is accurately calculated through the air pressure value of the air bag, overload alarm is conducted, and the overload problem of the commercial vehicle is better avoided.The temperature of the air bag is monitored in real time, the health degree of the air bag is simulated, and intelligent service is provided for the air suspension.

Description

technical field [0001] The invention relates to an electronically controlled air suspension system in the automotive field, in particular to an intelligent electronically controlled air suspension system for commercial vehicles. Background technique [0002] The air suspension system is a general term for suspensions that use air springs as elastic components. Air suspensions have gained extensive research interest due to their good road friendliness and ability to maintain the natural vibration frequency under arbitrary loads. The traditional air suspension adjusts the inflation and deflation of the airbag through the opening of the mechanical height valve, so as to keep the ride height of the vehicle constant. With the continuous development of vehicle control technology, the electronically controlled air suspension system is constantly replacing the traditional air suspension system. [0003] At present, electronically controlled air suspension systems are widely used a...
