Related technologies mostly adopt a built-in active air intake grille scheme to balance the needs of design and wind resistance reduction. However, the built-in active air intake grille scheme greatly affects the air intake amount of a cooling module and has poor flexibility, which makes it difficult to accurately match the actual air intake demand of the automobile, thereby affecting the thermal management of the vehicle. SUMMARY

[0013] When thermal management demand information indicates that an increase in air intake is required, the displacement of the active air intake grille in the direction from the front of the vehicle to the rear is determined based on the target location and the current location.

[0014] When thermal management demand information indicates that a reduction in air intake is required, the displacement of the active air intake grille in the direction from the rear of the vehicle to the front is determined based on the target location and the current location.

[0015] In one embodiment, adjusting the blades in the active air intake grille to a target opening includes:

[0016] Determine the current opening of the blades in the active air intake grille;

[0017] Based on the target opening and the current opening, determine the opening adjustment amount of the blades in the active air intake grille;

[0018] According to the opening adjustment amount, the blades in the active air intake grille are adjusted from the current opening to the target opening.

[0019] In one embodiment, the adjustment amount of the blade opening in the active air intake grille is determined based on the target opening and the current opening, including at least one of the following:

[0020] When thermal management demand information indicates that an increase in air intake is required, the amount of adjustment required to increase the opening of the blades in the active air intake grille is determined based on the target opening and the current opening.

[0021] When thermal management demand information indicates that the intake volume needs to be reduced, the amount of adjustment required to reduce the opening of the blades in the active intake grille is determined based on the target opening and the current opening.

[0022] In one embodiment, the active air intake grille is located between the front bumper and the crash beam in the longitudinal direction of the vehicle body.

[0023] Secondly, this application also provides a vehicle thermal management control device, comprising:

[0024] The determination module is used to obtain the vehicle's thermal management requirements information; based on the thermal management requirements information, it determines the target position of the active air intake grille in the longitudinal direction of the vehicle body and the target opening of the blades in the active air intake grille.

[0025] The adjustment module is used to move the active air intake grille to a target position along the longitudinal direction of the vehicle body and adjust the blades in the active air intake grille to a target opening degree, so as to perform thermal management of the vehicle through the active air intake grille.

[0033] The aforementioned vehicle thermal management control method, active air intake grille, controller, vehicle, and readable storage medium determine the target position and target blade opening of the active air intake grille based on the vehicle's thermal management requirements. This allows the active air intake grille to be moved to the target position along the vehicle's longitudinal direction and its blades to be adjusted to the target opening. This adjusts the airflow path and intake volume of the active air intake grille into the vehicle, thereby achieving vehicle thermal management. Because the active air intake grille can both move along the vehicle's longitudinal direction and adjust the blade opening, it allows for more flexible adjustment of the vehicle's intake volume and accurate matching of actual vehicle air intake needs.

[0045] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0046] In one embodiment, such as Figure 1 As shown, a vehicle thermal management control method is provided. This embodiment illustrates the application of this method to the ECU (Electronic Control Unit) of an automobile. It is understood that this method can also be applied to other components in an automobile, such as a control module or device specifically designed for vehicle thermal management, or the vehicle control unit (VCU), etc. In this embodiment, the method includes steps S101 to S103:

[0047] Step S101: The ECU obtains the vehicle's thermal management requirements information.

[0048] The vehicles can be, but are not limited to, various sedans, SUVs (sport utility vehicles, or suburban utility vehicles), MPVs (multi-Purpose Vehicles), sports cars, trucks, off-road vehicles, motorcycles, tricycles, electric vehicles, dump trucks, tractor-trailers, agricultural vehicles, and special vehicles (such as sanitation vehicles, snowplows, bulldozers, etc.). For example, the vehicles can be new energy vehicles.

[0049] Thermal management requirements information can be related to vehicle temperature control. For example, thermal management requirements information can be information on the need to effectively manage the various heat generated during vehicle operation to ensure that all vehicle components operate within a suitable temperature range, thereby improving vehicle reliability, safety, fuel economy, and driving range, and ultimately enhancing vehicle performance.

[0050] In some embodiments, the thermal management requirement information can be determined by comprehensively considering factors such as the vehicle's current driving status, driving mode, range, temperature differences between various vehicle components and the outside environment, and cabin temperature.

[0051] In some embodiments, the thermal management requirement information can correspond to the vehicle's thermal management requirements, which can be based on the heat dissipation requirements that the active grille shutter can meet. In some embodiments, the heat dissipation requirements have different levels, such as being divided into 1-5 levels, from level 1 to level 5, with the corresponding heat dissipation requirements ranging from lowest to highest. For example, for a gasoline vehicle, when the vehicle engine is first cold-started, in order to ensure that the engine temperature rises quickly to a suitable operating temperature, the corresponding thermal management requirements can be at a lower level, that is, the heat dissipation requirements are lower.

[0052] For example, when the vehicle is traveling at a high speed, the temperature of the various components of the vehicle does not exceed the preset maximum operating temperature and / or the ambient temperature outside the vehicle is lower than the preset temperature (such as 0°C), the thermal management requirement information can be minimal or no heat dissipation is required.

[0053] In some embodiments, thermal management requirements information may include at least one of the following: engine cooling requirements; air conditioning cooling requirements; motor cooling requirements; battery cooling requirements.

[0054] In step S102, the ECU determines the target position of the active air intake grille in the longitudinal direction of the vehicle body and the target opening of the blades in the active air intake grille based on the thermal management requirements information.

[0055] The longitudinal direction of the vehicle body is defined based on the vehicle body itself. Specifically, it can be a direction extending longitudinally along the vehicle body. The longitudinal direction of the vehicle body can include the direction from the front of the vehicle to the rear of the vehicle and the direction from the rear of the vehicle to the front of the vehicle.

[0056] An active grille shutter (AGS) is a type of air intake grille that actively adjusts the opening angle of the air intake based on the vehicle's operating conditions, essentially adjusting the opening of the blades. The active grille is a structural component installed at the front of the vehicle. Its main functions include guiding airflow into the car to aid in heat dissipation, influencing air resistance during driving, blocking foreign objects from entering the vehicle, and maintaining harmony with the vehicle's design structure.

[0057] In some embodiments, the amount of air entering the vehicle per unit time can vary depending on the position of the active air intake grille in the longitudinal direction of the vehicle body. For example, the farther the active air intake grille is from the vehicle bumper in the longitudinal direction of the vehicle body, the greater the corresponding air intake volume, and vice versa.

[0058] In some embodiments, the opening degree of the blades in the active air intake grille varies, and the corresponding air intake volume can vary. For example, a larger numerical value of the opening degree of the blades in the active air intake grille indicates a greater degree of openness of the blades, resulting in a greater amount of air entering the vehicle, thereby effectively meeting the vehicle's high heat dissipation requirements; conversely, a smaller numerical value of the opening degree of the blades in the active air intake grille indicates a smaller degree of openness of the blades, resulting in a smaller amount of air entering the vehicle.

[0059] In some embodiments, since both the position of the active air intake grille and the opening of its blades can affect the vehicle's air intake volume, the combination of the target position of the active air intake grille and the target opening of its blades corresponding to the same thermal management requirement information may not be unique. For example, the target positions corresponding to the same thermal management requirement information may include A and B, and the target openings may include C and D. A and C form combination 1, and B and D form combination 2. Although A and B are different, and C and D are different, the air intake volume effects achieved by combination 1 and combination 2 may be the same or different. For instance, the increased air intake volume through A is greater than the increased air intake volume through B, but the increased air intake volume through D is greater than the increased air intake volume through C. Therefore, the air intake volume effects achieved by combination 1 and combination 2 may be the same.

[0060] In some embodiments, the ECU can determine at least one set of adjustment schemes based on thermal management requirements information. These schemes include the target position of the active air intake grille and the target opening of the blades within the grille. When the number of adjustment schemes is greater than or equal to two, the ECU can evaluate each scheme separately based on vehicle drag and energy consumption control dimensions to determine the target position and blade opening of the active air intake grille from among these schemes. In some embodiments, the ECU can determine the target adjustment scheme based on real-time vehicle driving information, such as vehicle speed, to make the adjustment of the active air intake grille more aligned with actual driving needs. For example, at higher vehicle speeds, such as 100 km / h, the ECU prioritizes the adjustment scheme that shortens the distance between the active air intake grille and the foreground of the vehicle, thereby reducing drag at high speeds.

[0061] In step S103, the ECU moves the active air intake grille to the target position along the longitudinal direction of the vehicle body and adjusts the blades in the active air intake grille to the target opening, so as to perform thermal management of the vehicle through the active air intake grille.

[0062] In some embodiments, the vehicle may include moving components, such as tracks or drive motors. The ECU controls these moving components to move the active air intake grille along the longitudinal direction of the vehicle body to a target position and adjusts the opening of the blades within the grille to the target opening. This ensures the active air intake grille is positioned at the target location, and the blades control air intake according to the target opening, thereby achieving thermal management for the vehicle. In some embodiments, the movement of the active air intake grille and the adjustment of the blade opening can be performed simultaneously or sequentially. For example, the active air intake grille can be moved along the longitudinal direction of the vehicle body to the target position first, and then the blades can be adjusted to the target opening; alternatively, the blades can be adjusted to the target opening first, and then the active air intake grille can be moved along the longitudinal direction of the vehicle body to the target position. The order of the active air intake grille movement control and blade opening adjustment can be configured according to actual needs.

[0063] The aforementioned technical solution determines the target position and blade opening of the active air intake grille based on the vehicle's thermal management requirements. This allows the active air intake grille to be moved to the target position along the vehicle's longitudinal direction and its blades adjusted to the target opening. This adjusts the airflow path and intake volume into the vehicle, thus achieving thermal management. Because the active air intake grille can both move along the vehicle's longitudinal direction and adjust blade opening, it allows for more flexible adjustment of the vehicle's air intake volume and more accurate matching of actual air intake needs.

[0064] In one embodiment, such asFigure 2 As shown, the aforementioned "moving the active air intake grille along the longitudinal direction of the vehicle body to the target position" may include steps S201 to S203:

[0065] Step S201: The ECU determines the current position of the active air intake grille in the longitudinal direction of the vehicle body.

[0066] Step S202: The ECU determines the amount of displacement of the active air intake grille in the longitudinal direction of the vehicle body based on the target position and the current position.

[0067] In some embodiments, the ECU can determine the amount of displacement of the active air intake grille in the longitudinal direction of the vehicle body based on a preset algorithm, according to the target position and the current position. For example, the preset algorithm may be to establish a coordinate axis in the longitudinal direction of the vehicle body with a specific component of the vehicle (such as a bumper or anti-collision beam) as the origin, convert the target position and the current position into specific coordinates, namely target coordinates and current coordinates, and determine the amount of displacement by the difference between the two coordinates.

[0068] Step S203: The ECU moves the active air intake grille from its current position to the target position along the longitudinal direction of the vehicle body according to the displacement amount.

[0069] In some embodiments, the vehicle design uses a drive motor to move the active air intake grille. Accordingly, the ECU can determine the required rotational speed of the drive motor based on the amount of displacement, and move the active air intake grille from its current position to the target position along the longitudinal direction of the vehicle body by controlling the rotational speed of the drive motor.

[0070] By determining the current and target positions of the active air intake grille in the longitudinal direction of the vehicle body, the displacement of the active air intake grille in the longitudinal direction of the vehicle body can be determined more accurately, thereby moving the active air intake grille from its current position to its target position along the longitudinal direction of the vehicle body.

[0071] In one embodiment, the aforementioned "determining the displacement of the active air intake grille in the longitudinal direction of the vehicle body based on the target position and the current position" may include at least one of the following: when the thermal management demand information indicates that an increase in air intake is required, the ECU determines the displacement of the active air intake grille in the direction from the front to the rear of the vehicle based on the target position and the current position; when the thermal management demand information indicates that a decrease in air intake is required, the ECU determines the displacement of the active air intake grille in the direction from the rear to the front of the vehicle based on the target position and the current position.

[0072] In some embodiments, when thermal management demand information indicates that an increase in air intake is required, the amount of displacement of the active air intake grille in the direction from the front of the vehicle to the rear is determined based on the target location and the current location. That is, the distance between the active air intake grille and the rear of the vehicle (such as the rear bumper) is shortened to increase the air intake.

[0073] In some embodiments, when thermal management demand information indicates a need to reduce air intake, the amount of displacement of the active air intake grille in the direction from the rear of the vehicle to the front is determined based on the target location and the current location. That is, the distance between the active air intake grille and the frontmost part of the vehicle (such as the front bumper) is shortened to reduce air intake.

[0074] The above technical solutions determine different displacement amounts for different thermal management needs. Specifically, when it is necessary to increase the air intake, i.e. increase heat dissipation, the displacement amount of the active air intake grille in the direction from the front to the rear of the vehicle is determined, thereby reducing air obstruction and increasing the air intake. When it is necessary to reduce the air intake, i.e. reduce heat dissipation, the displacement amount of the active air intake grille in the direction from the rear to the front of the vehicle is determined, thereby increasing air obstruction and reducing the air intake.

[0075] In one embodiment, the aforementioned "adjusting the blades in the active air intake grille to the target opening" may include: the ECU determining the current opening of the blades in the active air intake grille; determining the opening adjustment amount of the blades in the active air intake grille based on the target opening and the current opening; and adjusting the blades in the active air intake grille from the current opening to the target opening according to the opening adjustment amount.

[0076] In some embodiments, the ECU can execute the actions of "adjusting the blades of the active air intake grille to the target opening" and "moving the active air intake grille along the longitudinal direction of the vehicle body to the target position" simultaneously or sequentially. For example, the ECU can first move the active air intake grille along the longitudinal direction of the vehicle body to the target position, and then adjust the blades of the active air intake grille to the target opening. Alternatively, the ECU can first adjust the blades of the active air intake grille to the target opening, and then move the active air intake grille along the longitudinal direction of the vehicle body to the target position.

[0077] By determining the opening adjustment amount of the blades in the active air intake grille based on the current opening and target opening of the blades, the opening adjustment of the blades in the active air intake grille can be achieved more accurately from the current opening to the target opening.

[0078] In one embodiment, the aforementioned "determining the opening adjustment amount of the blades in the active air intake grille based on the target opening and the current opening" may include at least one of the following: when the thermal management demand information indicates that an increase in air intake is required, determining the opening adjustment amount by which the blades in the active air intake grille need to be increased based on the target opening and the current opening; when the thermal management demand information indicates that a decrease in air intake is required, determining the opening adjustment amount by which the blades in the active air intake grille need to be decreased based on the target opening and the current opening.

[0079] In some embodiments, the amount of adjustment required to increase the opening can be to make the blades fully open or to make the blades partially open, that is, it is only necessary to increase the opening compared to the original opening; similarly, the amount of adjustment required to decrease the opening can be to make the blades fully closed or to decrease the opening compared to the original opening.

[0080] The above technical solutions determine different opening adjustment amounts for different thermal management needs. Specifically, when it is necessary to increase the intake volume, i.e. increase heat dissipation, the opening adjustment amount of the blades in the active air intake grille that needs to be increased is determined, thereby reducing air obstruction and achieving an increase in intake volume; when it is necessary to reduce the intake volume, i.e. reduce heat dissipation, the opening adjustment amount of the blades in the active air intake grille that needs to be decreased is determined, thereby increasing air obstruction and achieving a decrease in intake volume.

[0081] In one embodiment, the aforementioned active air intake grille is located between the front bumper (i.e., the front bumper) and the anti-collision beam (i.e., the front anti-collision beam) in the longitudinal direction of the vehicle body.

[0082] In some embodiments, when thermal management demand information indicates a need to increase air intake, the ECU shortens the distance between the active air intake grille and the bumper beam to increase air intake. When the current position information of the active air intake grille indicates that the distance between the active air intake grille and the bumper beam is zero, the ECU stops shortening the distance between the active air intake grille and the bumper beam.

[0083] In some embodiments, when thermal management demand information indicates a need to reduce air intake, the ECU shortens the distance between the active air intake grille and the front bumper to reduce air intake. When the current position information of the active air intake grille indicates that the distance between the active air intake grille and the front bumper is equal to 0, the ECU stops shortening the distance between the active air intake grille and the front bumper.

[0084] By installing a movable active air intake grille between the front bumper and the anti-collision beam, not only can flexible adjustment of air intake be achieved, along with more flexible vehicle thermal management, but the original design structure of the vehicle is also preserved. For example, the car grille is the outermost layer of the front end, located above the front bumper and between the headlights, and is one of the visual elements of the vehicle's front face. When the active air intake grille is installed between the front bumper and the anti-collision beam, the active air intake grille and the grille can exist in independent front and rear spaces, avoiding physical conflict. There is no need to change the original shape, position, and function of the grille, thus directly preserving the original car grille structure.

[0085] In one exemplary embodiment, such as Figure 3 As shown, a traditional built-in AGS solution is presented, where the AGS is positioned between the main and secondary anti-collision beams. This results in higher overall vehicle drag compared to an external AGS solution, and the cooling module's airflow is also lower. For example... Figure 4 As shown, an external AGS solution is presented. After applying an external AGS, the overall vehicle drag is further reduced compared to an internal AGS, while the air intake of the cooling module is significantly increased. Although changing from an internal to an external AGS offers the aforementioned advantages, it also presents the following problems: it requires altering the original vehicle front-end structure design; the arrangement and motion envelope of the AGS blades are limited; and the external AGS replacing the air intake grille has a certain impact on the styling. Based on the above analysis, to ensure that the original vehicle structure remains largely unchanged (retaining the air intake grille features), while simultaneously reducing overall vehicle drag and improving overall vehicle cooling performance, this application proposes a vehicle thermal management control method:

[0086] like Figure 5 As shown, from a side view of the vehicle, a partial structural diagram of the AGS (Air Gauge System) corresponding to the vehicle's thermal management control method is presented. When the vehicle's air intake demand is low, the AGS blades close and slide forward as a whole. When it slides to its maximum forward position, it fits against the air intake grille in the front bumper, achieving the same drag reduction effect as an external AGS. When the vehicle's air intake demand is high, the AGS first slides backward as a whole. If the demand is still not met when it slides to its maximum rearward position, the AGS blades will open, further increasing the air intake of the cooling module.

[0087] like Figure 6 As shown, viewed from the front of the vehicle, this is a schematic diagram of the AGS (Automatic Guided Vehicle) structure corresponding to the vehicle's thermal management control method, i.e., the front view. The sliding AGS main structure uses an AGS motor to drive the blades to rotate, thus opening and closing the blades. Simultaneously, the AGS frame is connected to the tracks via connecting rods, and the movement of the tracks enables the AGS to slide forward and backward as a whole.

[0088] like Figure 7As shown, viewed from the driver's side to the passenger's side, this is a partial structural diagram of the AGS (Automatic Guided Vehicle) of the vehicle corresponding to the thermal management control method, i.e., a side view. The sliding AGS main structure uses an AGS motor to drive the blades to rotate, thereby opening and closing the blades. Simultaneously, the AGS frame is connected to the tracks via connecting rods, and the movement of the tracks enables the AGS to slide forward and backward as a whole.

[0089] like Figure 8 The diagram illustrates a possible sliding AGS control logic. In the diagram, lev represents the cooling request level for the relevant component. A higher level indicates a greater cooling demand, requiring an increase in the vehicle's airflow; conversely, a lower level requires a decrease in airflow. For example, lev 0 is the lowest level, and lev 3 is the highest level. Specifically, when the vehicle is powered on and the AGS fault signal is normal (i.e., no fault exists), the ECU adjusts the position and opening of the AGS based on the cooling request levels of various components such as the engine, electric drive system, and air conditioning.

[0090] If the cooling request level is greater than Lev 0, slide AGS to the rear limit position and check if the blades are fully open. If the blades are not fully open and the cooling request level is greater than lev 0 and less than lev 3, keep AGS in the rear limit position and close the blades. If the blades are not fully open and the cooling request level is greater than lev 3, keep AGS in the rear limit position and fully open the blades.

[0091] If the cooling request level is less than Lev 0, check if AGS is in the rear limit position. If AGS is in the rear limit position, first close the AGS blades and slide AGS to the front limit position.

[0092] In the above technical solution, the AGS can slide from the middle position of the main and secondary anti-collision beams (rear limit) to a position that fits against the air intake grille of the front bumper (front limit). The AGS opening process includes two steps: first sliding backward, then opening the blades. The AGS closing process includes two steps: first closing the blades, then sliding forward. The main structure of the AGS is connected to the tracks, and the forward and backward sliding of the AGS is achieved through the movement of the tracks. The above technical solution can achieve wind resistance reduction and cooling effects similar to those of an external AGS; at the same time, it retains the characteristics of the front air intake grille (middle grille) and does not affect the original structural design of the vehicle.

[0093] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0094] Based on the same inventive concept, this application also provides a vehicle thermal management control device for implementing the vehicle thermal management control method described above. The solution provided by this device is similar to the solution described in the above method; therefore, the specific limitations of one or more vehicle thermal management control device embodiments provided below can be found in the limitations of the vehicle thermal management control method described above, and will not be repeated here.

[0095] In one exemplary embodiment, such as Figure 9 As shown, a vehicle thermal management control device 900 is provided, comprising:

[0096] The module 901 is used to obtain the vehicle's thermal management requirements information; based on the thermal management requirements information, it determines the target position of the active air intake grille in the longitudinal direction of the vehicle body and the target opening of the blades in the active air intake grille.

[0097] The adjustment module 902 is used to move the active air intake grille to a target position along the longitudinal direction of the vehicle body and adjust the blades in the active air intake grille to a target opening, so as to perform thermal management of the vehicle through the active air intake grille.
