Description

Technical Field

[0001] The invention relates to the technical field of engine instrument display, and more particularly to an instrument parking regeneration progress bar display method. Background Art

[0002] Parking regeneration means that when the carbon load reaches a level that makes it impossible to burn off the soot and solve the blockage problem during driving, the driver needs to stop the car and press the regeneration switch on the car to perform parking regeneration. Parking regeneration is a regeneration method for the diesel particulate filter (DPF). The DPF is a ceramic filter installed in the diesel engine emission system. Its main function is to capture harmful particles in the exhaust gas, reduce the emission of particulate matter through filtration and oxidation, and meet the National VI emission standards. When the particulate content in the collector reaches a certain value, it will cause the engine performance to decline. If regeneration is not performed in time, it will cause the DPF to be blocked, affect the engine power, and cause irreversible damage to the DPF.

[0003] During the parking regeneration process, the engine idle speed will increase and enter the heating stage. This stage includes heating stage 1 and heating stage 2, during which the engine speed will continue to increase to reach the temperature required by the particulate filter, thereby starting the regeneration process.

[0004] Regeneration phase: After the heating phase, the engine enters the regeneration phase, which is a key step in clearing the accumulation of particles in the particle filter. During this phase, the engine speed will continue to increase until the regeneration is complete.

[0005] Cooling phase: After regeneration is completed, the engine speed is appropriately reduced and enters the cooling phase. This phase marks the end of the entire regeneration process. At this time, the regeneration indicator light goes out and the driver can continue driving safely.

[0006] Through the implementation of these stages, the engine can effectively remove accumulated soot and other pollutants, thereby improving engine efficiency and performance, while also contributing to environmental protection and energy conservation.

[0007] A reminder light will light up on the unit's instrument panel to remind the user that the engine is regenerating. The regeneration icon on the instrument panel will also be displayed during the engine's parking regeneration process, and words such as "cannot load" will also appear to remind the user that the engine cannot be loaded or other actions. Under normal circumstances, the engine's regeneration time is generally completed in about 30 minutes, the engine speed will return from high speed to idle, the regeneration icon and prompt words on the instrument panel will disappear, and the engine can work normally at this time. However, there is no progress bar displayed during the regeneration process, and there is no prompt when exiting the regeneration due to regeneration failure for some reason. This requires the user to stay by the engine and keep looking at the instrument panel to confirm whether the engine regeneration stage has been successfully completed. This not only poses a safety hazard to the user, but also increases the workload for the user. Summary of the invention

[0008] The technical problem to be solved by the present invention is to provide a method for displaying a parking regeneration progress bar on an instrument panel in view of the deficiencies in the prior art, thereby solving the technical problem that the absence of a progress bar on the prior instrument panel regarding engine regeneration poses a safety hazard to the user and increases the user's workload.

[0009] The method for displaying a parking regeneration progress bar on an instrument panel of the present invention comprises: when the engine is performing parking regeneration, detecting the regeneration stage of the engine, setting the regeneration progress according to the regeneration stage of the engine, and displaying the regeneration progress on the instrument panel.

[0010] As a further improvement, the method for setting the regeneration progress is:

[0011] The parking regeneration stages include a normal stage, a start stage, a heating stage 1, a heating stage 2, a running stage and a cooling stage;

[0012] The regeneration schedule includes a first loading partition, a second loading partition, a third loading partition, a fourth loading partition, and a fifth loading partition;

[0013] When it is detected that the regeneration phase of the engine switches from the normal phase to the heating phase, the first loading partition starts loading;

[0014] When it is detected that the regeneration stage of the engine switches from the first heating stage to the second heating stage, the first loading partition is loaded;

[0015] When it is detected that the regeneration stage of the engine is in the second heating stage, the second loading partition starts loading;

[0016] When it is detected that the regeneration stage of the engine switches from the second heating stage to the operation stage, the loading of the second loading partition is completed;

[0017] When it is detected that the regeneration phase of the engine is in the running phase, the third loading partition starts loading;

[0018] When the regeneration phase of the engine switches from the running phase to the cooling phase, the loading of the third loading partition is completed;

[0019] When it is detected that the regeneration phase of the engine is in the cooling phase, the fourth loading partition starts loading;

[0020] When it is detected that the regeneration phase of the engine switches from the cooling phase to the normal phase, the loading of the fourth loading partition is completed.

[0021] Furthermore, the interval of the first loading partition is 0-7% of the regeneration progress.

[0022] Furthermore, the interval of the second loading partition is 7%-23% of the regeneration progress.

[0023] Furthermore, the interval of the third loading partition is 23%-86% of the regeneration progress.

[0024] Furthermore, the interval of the fourth loading partition is 86%-100% of the regeneration progress.

[0025] Beneficial Effects

[0026] The advantages of the present invention are:

[0027] The present invention obtains the regeneration stage of the engine. When the engine performs parking regeneration, the regeneration progress is set according to the regeneration stage of the engine, and the regeneration progress is displayed on the instrument. The progress of the parking regeneration can be intuitively understood through the regeneration progress, thereby avoiding the safety hazard of the user viewing the parking regeneration process and reducing the workload of viewing.
