Embodiment 1

[0036] An electronically controlled air suspension system for a commercial vehicle, including an ECAS processor, a height sensor for detecting the height of the air suspension; the ECAS processor is connected with the vehicle air source and the suspension airbag, and the ECAS processor includes an ECAS solenoid valve, an ECSAS The inlet end of the solenoid valve is connected to the air source of the vehicle, and the outlet end is connected to the suspension airbag. The ECAS processor controls the inflation and deflation of the suspension airbag by controlling the ECAS solenoid valve; each suspension airbag is connected to a switch electromagnetic The valve 26 also includes an air pressure sensor, which is connected with the suspension air bag for detecting the pressure of the suspension air bag. Wherein the number of airbags in this implementation is 4, which are respectively the left front axle airbag 27, the right front axle airbag 28, the left rear axle airbag 29 and the rig...

Embodiment 2

[0090] The difference between this embodiment and Embodiment 1 is that a more detailed calibration interval is provided during calibration, and calibration is carried out at no-load, quarter-load, half-load, three-quarter-load, and full-load.

Embodiment 3

[0092] The difference between this embodiment and Embodiment 1 is that: the up key 22 and the down key 23 are separate keys.

Abstract

The invention relates to the field of commercial vehicle air suspension, and discloses a commercial vehicle electronic control air suspension system and a load identification method, the commercial vehicle electronic control air suspension system comprises an ECAS processor and a height sensor used for detecting the height of an air suspension; the ECAS processor is connected with the whole vehicle air source and the suspension air bag, the ECAS processor comprises an ECAS electromagnetic valve, the air inlet end of the ECSAS electromagnetic valve is connected with the whole vehicle air source, the air outlet end of the ECSAS electromagnetic valve is connected with the suspension air bag, and the ECAS processor controls inflation and deflation of the suspension air bag by controlling the ECAS electromagnetic valve; each suspension air bag is connected with a switch electromagnetic valve, and the air pressure sensors are connected with the suspension air bags and used for detecting the pressure of the suspension air bags. The number of the air pressure sensor is one, the air pressure sensor is connected with pipelines of all the suspension air bags in parallel, and monitoring of pressure of different suspension air bags is achieved by controlling different switch electromagnetic valves. The system has the advantages of accurate monitoring, simple and reliable logic and the like.

Description

technical field [0001] The invention relates to the field of commercial vehicle air suspension, in particular to a commercial vehicle electronically controlled air suspension system and a load identification method. Background technique [0002] Since the implementation of GB1589-2016, it can be clearly felt that the country has started stricter regulations on freight vehicles. On the one hand, this is to solve the historical problem of ultra-long and ultra-wide vehicles, and on the other hand, it is hoped that the entire freight industry will develop in the direction of high-speed logistics, energy-saving and intensive. It is against this background that air suspension has gradually received more attention. [0003] As far as the current domestic freight situation is concerned, the air suspension is almost only used in drop-and-hook high-speed transport tractors and large closed trucks. The tractor is equipped with air suspension, which can pick up and drop the trailer fa...
