Abstract
Description
Technical Field

[0002] Active Grille Shutter (AGS) is a vehicle's grille adjustment system that can control the air intake volume of the engine compartment and the wind resistance of the entire vehicle by changing the opening and closing angles of the grille, thereby improving the vehicle's fuel economy and accelerating the engine warm-up process.
[0003] When the vehicle is using AGS or AGS self-checking, it may encounter a stuck situation. At present, the AGS is usually stopped at the maximum opening allowed by the current stuck position. For example, if it is a closed stuck, the AGS is kept fully open. If it is an open stuck, the AGS is opened to the stuck point and the instrument prompts to wait for maintenance. Or directly execute the normal AGS working strategy.

[0048] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.
[0049] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.
[0050] Figure 1 A schematic diagram of an implementation flow of a self-correction method for an active air intake grille provided in an embodiment of the present invention is described in detail as follows.
[0051] Step 101, when the active air intake grille AGS performs a self-check, determine the angle corresponding to the stuck point position.
[0052] Optionally, when the AGS encounters a jam during normal operation or when the vehicle is started, the AGS self-check is performed to determine the angle corresponding to the jam point position. Optionally, the angle corresponding to the jam point position includes: a maximum angle and a minimum angle. The AGS may encounter a jam during normal operation or when the AGS encounters a jam during self-check. At this time, the maximum angle and minimum angle corresponding to the jam point position during the operation of the AGS are recorded.
[0053] It should be noted that during the AGS self-test, AGS will perform a single opening and closing action. If the action is blocked, AGS will perform multiple rounds of opening and closing actions in an attempt to break through the sticking point and perform normal action. The specific self-test methods vary from manufacturer to manufacturer.
[0054] It should be noted that the corresponding relationship between the AGS angle and the opening is not limited in this embodiment. For example, the AGS blade angle of 0° corresponds to an opening of 0; the blade angle of 90° corresponds to an opening of 100; or the AGS blade angle of 0° corresponds to an opening of 100; the blade angle of 90° corresponds to an opening of 0. Below, we take the AGS blade angle of 0° corresponding to an opening of 0, and the blade angle of 90° corresponding to an opening of 100 as an example for description.
[0055] Optionally, when the AGS performs self-test, after determining the angle corresponding to the stuck point position, the following steps may also be performed:
[0056] Detect whether the difference between the maximum angle and the minimum angle is less than the preset angle;
[0057] When the difference between the maximum angle and the minimum angle is not less than the preset angle, the AGS is controlled to execute a normal working strategy.
[0058] In one embodiment, the preset angle may be 90°. When the difference between the maximum angle and the minimum angle is greater than or equal to 90°, it indicates that the current AGS does not have a stuck fault, so the AGS can be controlled to execute a normal working strategy.
[0059] When the difference between the maximum angle and the minimum angle is less than 90°, it indicates that the current AGS has a stuck fault, and step 102 and subsequent steps are executed.
[0060] Step 102: Determine the current opening range of the AGS according to the angle corresponding to the stuck point position.
[0061] Optionally, this step may include: when the difference between the maximum angle and the minimum angle is less than a preset angle, determining that the maximum angle is the maximum opening of the current opening range of the AGS, and the minimum angle is the minimum opening of the current opening range of the AGS. That is, the current opening range of the AGS is an opening range bounded by the maximum opening and the minimum opening.
[0062] In this embodiment, when the difference between the maximum angle and the minimum angle is less than 90°, it indicates that the current AGS has a stuck fault. At this time, the controller obtains the recorded maximum angle as the maximum opening currently available for the AGS, recorded as Vmax, and obtains the recorded minimum angle as the minimum opening currently available for the AGS, recorded as Vmin.
[0063] Step 103: Determine preset parameters corresponding to the vehicle according to the current opening range of the AGS.
[0064] Optionally, this step may include:
[0065] By using a preset opening-parameter table, the maximum preset parameter of the vehicle corresponding to the maximum opening is determined by looking up the table;
[0066] By using the preset opening-parameter table, the minimum preset parameters of the vehicle corresponding to the minimum opening are determined by looking up the table.
[0067] Optionally, the preset parameters may include the engine water temperature, the transmission oil temperature or the air conditioning pressure value. We take the engine water temperature as an example for description, and the preset opening-parameter table may be as shown in Table 1. It should be noted that Table 1 is only an example and does not represent the actual correspondence between the engine water temperature and the opening.
[0068] Table 1
[0069]
[0070] The water temperature corresponding to Vmax (ie, the maximum preset parameter) and the water temperature corresponding to Vmin (ie, the minimum preset parameter) are obtained by table lookup and interpolation.
[0071] Step 104, obtaining the current real-time parameters of the vehicle.
[0072] For example, obtain the real-time water temperature of the vehicle's current engine.
[0073] Step 105 , determining the opening of the AGS within the current opening range of the AGS according to the real-time parameters and the preset parameters, and controlling the AGS to execute the opening.
[0074] Optionally, determining the opening of the AGS within the current opening range of the AGS according to the real-time parameters and the preset parameters may include:
[0075] Check whether the real-time parameter is greater than or equal to the maximum preset parameter;
[0076] When the real-time parameter is greater than or equal to the maximum preset parameter, the opening of the AGS is determined to be the maximum opening;
[0077] That is, when the real-time parameter is greater than or equal to the maximum preset parameter, the opening of the AGS is Vmax. At this time, the AGS opening is at its maximum to the sticking point, so that the AGS blades will not generate force with the sticking point, and thus will not be damaged.
[0078] When the real-time parameter is less than the maximum preset parameter, the opening of the AGS is determined to be the opening corresponding to the preset opening-parameter table, and the AGS is controlled to execute the requested opening of the controller;
[0079] That is, when the real-time parameter is less than the maximum preset parameter, the opening degree requested by the controller itself will not exceed the sticking point, so it is sufficient to control the AGS to normally execute the requested opening degree of the controller.
[0080] Similarly, check whether the real-time parameter is less than or equal to the minimum preset parameter;
[0081] When the real-time parameter is less than or equal to the minimum preset parameter, the opening of the AGS is determined to be the minimum opening.
[0082] When the real-time parameter is less than or equal to the minimum preset parameter, the opening of the AGS is Vmin. At this time, the AGS opening is as small as the sticking point. In this way, the AGS blade will not generate force with the sticking point, so the AGS blade will not be damaged.
[0083] When the real-time parameter is greater than the maximum preset parameter, the opening of the AGS is determined to be the opening corresponding to the preset opening-parameter table, and the AGS is controlled to execute the requested opening of the controller.
[0084] When the real-time parameter is greater than the minimum preset parameter, the opening requested by the controller itself will not exceed the sticking point, so it is sufficient to control the AGS to normally execute the requested opening of the controller.
[0085] It should be noted that when the AGS is stuck, the opening angle range of the AGS is greater than Vmin and less than Vmax. Within this range, the AGS strategy can be executed normally. When it exceeds this range, the maximum opening angle of the AGS is Vmax, and the minimum opening angle is Vmin, that is, it reaches the sticking point. This can maximize the effect of maintaining the vehicle cabin temperature and reducing wind resistance, while avoiding contact force between the AGS blades and the sticking point, causing damage.
[0086] The following is a specific example of a method for self-correction of an active air intake grille. Figure 2 shown.
[0087] When the AGS is running normally, check whether it is stuck. If it is stuck, perform AGS self-check, or when the vehicle is started, perform AGS self-check;
[0088] Record the maximum and minimum angles corresponding to the stuck point position;
[0089] Check whether the difference between the maximum angle and the minimum angle is less than 90°;
[0090] When the difference between the maximum angle and the minimum angle is not less than 90°, the AGS is controlled to execute the normal working strategy.
[0091] When the difference between the maximum angle and the minimum angle is less than 90°, the current opening range of the AGS is determined to be the range consisting of the maximum angle and the minimum angle, and the maximum opening of the current opening range of the AGS is recorded as Vmax, and the minimum opening of the current opening range of the AGS is recorded as Vmin.
[0092] The maximum water temperature corresponding to the maximum opening is obtained by looking up the table, and the maximum water temperature is recorded as Tmax. At the same time, the minimum water temperature corresponding to the minimum opening is obtained by looking up the table, and the minimum water temperature is recorded as Tmin.
[0093] Detect whether the current water temperature T is greater than or equal to Tmax. If the current water temperature T is greater than or equal to Tmax, request the opening of AGS to be Vmax. If the current water temperature T is less than Tmax, control the AGS to execute the requested opening of the controller.
[0094] Detect whether the current water temperature T is less than or equal to Tmin. If the current water temperature T is less than or equal to Tmax, request the AGS opening to be Vmin. If the current water temperature T is greater than Tmax, control the AGS to execute the requested opening of the controller.
[0095] The above-mentioned self-correction method of the active air intake grille determines the current opening range of the AGS by recording the angle corresponding to the position of the AGS stuck point; determines the preset parameters corresponding to the vehicle based on the current opening range of the AGS; obtains the current real-time parameters of the vehicle; and determines the opening of the AGS within the current opening range of the AGS based on the real-time parameters and the preset parameters, and controls the AGS to execute the determined opening, so as to achieve the effect of maintaining the cabin temperature and reducing wind resistance to the greatest extent when the AGS is stuck, and at the same time avoids the contact force between the AGS blade and the stuck point to cause damage, thereby extending the service life of the AGS blade.
[0096] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
