Embodiment Construction

[0033] Below in conjunction with specific embodiment, the present invention is described in further detail:

[0034] A commercial vehicle dryer control method, such as figure 1 shown, including:

[0035] S1. Turn on the drying tank replacement warning system;

[0036] S2. Obtain air compressor displacement information P and air compressor and engine transmission ratio information R, and record EAD-air compressor status information and EEC1-engine speed information through the vehicle CAN network;

[0037] S3. Perform algorithm control on the above data;

[0038] S4. Make a logical judgment on the cumulative sum of the pump air volume of the stage air compressor;

[0039] S5. After the accumulated air volume of the air compressor pump and C12 reach the warning set value H, the drying tank replacement warning system prompts the replacement of the drying tank;

[0040] S6. Operate the one-key recovery button to eliminate the alarm.

[0041] Step S3 includes:

[0042] S3.1. ...

Abstract

The invention belongs to the technical field of vehicle chassis braking systems, and relates to a control method for a commercial vehicle dryer, comprising: opening a drying tank replacement warning system; acquiring air compressor displacement information P and air compressor and engine transmission ratio information R, The vehicle CAN network records the EAD-air compressor status information and EEC1-engine speed information; performs algorithm control on the above data; makes logical judgment on the cumulative sum of the air compressor pump air volume at the stage; the cumulative air compressor air volume and C12 reach the early warning setting After setting the value H, the drying tank replacement warning system prompts to replace the drying tank; operate the one-key recovery button to eliminate the alarm. The invention is suitable for the application of drying tanks with different performances, and different application type buttons are set to correspond to drying tanks with different performances, so as to ensure more accurate application effects; no additional processor is required, and the regeneration gas of the dryer is automatically adjusted according to the pumping volume of the air compressor. amount to ensure the drying effect during the life cycle of the dryer.

Description

technical field [0001] The invention belongs to the technical field of vehicle chassis braking systems, and relates to a control method of a commercial vehicle dryer. Background technique [0002] The brake system commonly used in commercial vehicles is air brake, and the cleanliness of the compressed air is crucial to the function of the brake system. The treatment of compressed air mainly comes from dryers. At present, the control methods widely used in dryers are: 1. Ordinary mechanical pressure control; 2. Electronically controlled intelligent pressure control. The above two controls basically use the same control logic throughout the entire life cycle of the dryer, and cannot be adjusted according to the degree of use of the dryer. At the same time, there is no warning system for the need to replace the drying tank to ensure that the driver replaces the drying tank in time to achieve. The drying effect that meets the requirements cannot be better matched with different...
