Technical Field

[0001] This invention relates to the field of automotive technology, and more particularly to a method, apparatus, device, and storage medium for controlling the air intake grille. Background Technology

[0002] The grille is a crucial component of a car's front styling, influencing the overall design and serving as the air intake for the engine compartment. Currently, to reduce wind resistance and fuel consumption, an increasing number of vehicles are considering active grille shutters, which can control the size of the front air intake and reduce unnecessary internal drag. Existing active grille shutters typically use signals such as current vehicle operating parameters as input, which, after processing with a specific logic strategy, output signals to control the opening and closing of the grille.

[0003] However, the above-mentioned grille control scheme does not control the grille opening accurately enough, and the control is performed after calculating the grille opening value at the current moment, which results in a delay and leads to poor vehicle system performance.

[0007] Obtain historical driving parameters, vehicle driving information, and current vehicle operating parameters;

[0008] The control strategy is determined based on the amount of data for the air intake grille control parameters in the historical driving parameters.

[0009] The opening of the air intake grille is controlled based on the control strategy, the historical driving parameters, the vehicle driving information, and the vehicle's current operating parameters.

[0010] Optionally, determining the control strategy based on the amount of data for the air intake grille control parameters in the historical driving parameters includes:

[0011] When the data volume of the air intake grille control parameter is within the first data volume range, a preset first strategy is used as the control strategy. The preset first strategy is to control the air intake grille opening based on the influence value of the air intake grille opening on the vehicle engine coolant temperature.

[0012] When the data volume of the air intake grille control parameter is in the second data volume range, a preset second strategy is used as the control strategy. The preset second strategy is to control the opening of the air intake grille according to the relationship between the air intake grille control parameter and the vehicle fuel consumption value.

[0013] When the data volume of the air intake grille control parameters is in the third data volume range, the preset third strategy is used as the control strategy.

[0030] The grille opening value corresponding to the second target fuel consumption value in the third similar historical parameter list is used as the fourth air intake grille opening value;

[0031] The opening of the air intake grille is controlled according to the opening values ​​of the third and fourth air intake grilles at a preset frequency.

[0032] Optionally, determining the impact of the grille opening on the engine coolant temperature based on the historical driving parameters (no control parameters for the grille) and the current vehicle operating parameters includes:

[0033] Based on the engine coolant temperature with no control parameters for the air intake grille in the historical driving parameters, it was determined that there was no active control of the coolant temperature.

[0034] The influence of the air intake grille opening on the engine coolant temperature is determined based on the current grille opening value in the vehicle's current operating parameters, the coolant temperature without active control, and the preset lower limit of coolant temperature.

[0035] Optionally, determining the first air intake grille opening value based on the water temperature influence value and the vehicle's current operating parameters includes:

[0036] The first air intake grille opening value is determined based on the temperature difference between the current engine coolant temperature and the preset upper limit value in the vehicle's current operating parameters, the current grille opening value, and the coolant temperature influence value.

[0037] Furthermore, to achieve the above objectives, the present invention also proposes an air intake grille control device, characterized in that the air intake grille control device comprises:

[0040] The grille control module is used to control the opening degree of the air intake grille based on the control strategy, the historical driving parameters, the vehicle driving information, and the vehicle's current operating parameters.

[0041] Furthermore, to achieve the above objectives, the present invention also proposes an air intake grille control device, the air intake grille control device comprising: a memory, a processor, and an air intake grille control program stored in the memory and executable on the processor, the air intake grille control program being configured to implement the air intake grille control method as described above.

[0042] In addition, to achieve the above objectives, the present invention also proposes a storage medium storing an air intake grille control program, which, when executed by a processor, implements the air intake grille control method as described above.

[0043] This invention discloses a method for determining a control strategy based on the amount of data for the air intake grille control parameters in the historical driving parameters, by acquiring historical driving parameters, vehicle driving information, and current vehicle operating parameters. The air intake grille opening is then controlled based on the control strategy, historical driving parameters, vehicle driving information, and current vehicle operating parameters. Because this invention acquires relevant parameters, determines the control strategy based on the amount of data for the air intake grille control parameters, and then calculates the air intake grille opening based on the control strategy and the aforementioned parameters, it can control the air intake grille opening more precisely. Furthermore, by combining vehicle driving information to calculate and proactively control the air intake grille opening at the next moment, the overall vehicle system performance is optimized.

[0050] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0051] Reference Figure 1 , Figure 1This is a schematic diagram of the air intake grille control device structure in the hardware operating environment involved in the embodiments of the present invention.

[0052] like Figure 1 As shown, the air intake grille control device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen or an input unit such as a keyboard; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wireless-Fidelity (Wi-Fi) interface). The memory 1005 may be a high-speed random access memory (RAM) or a stable non-volatile memory (NVM), such as a disk drive. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0053] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the air intake grille control device, and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0054] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a data storage module, a network communication module, a user interface module, and an air intake grille control program.

[0055] exist Figure 1 In the air intake grille control device shown, the network interface 1004 is mainly used for data communication with the network integrated platform workstation; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and memory 1005 in the air intake grille control device of the present invention can be set in the air intake grille control device, and the air intake grille control device calls the air intake grille control program stored in the memory 1005 through the processor 1001 and executes the air intake grille control method provided in the embodiment of the present invention.

[0056] Based on the above hardware structure, an embodiment of the air intake grille control method of the present invention is proposed.

[0057] Reference Figure 2 , Figure 2This is a flowchart illustrating the first embodiment of the air intake grille control method of the present invention.

[0058] In this embodiment, the air intake grille control method includes the following steps:

[0059] Step S10: Obtain historical driving parameters, vehicle driving information, and current vehicle operating parameters.

[0060] It should be noted that the execution subject of the method in this embodiment can be an air intake grille control device with data processing, network communication and program running functions, such as an automotive electronic control unit (ECU), or other electronic devices that can achieve the same or similar functions. This embodiment does not limit this.

[0061] It's worth noting that historical driving parameters can be obtained through the vehicle network. These parameters can include both grille control parameters and historical parameters without grille control parameters. Grille control parameters can be from vehicles equipped with active grille control, and may include engine coolant temperature, current fuel consumption, grille opening, vehicle speed, fan speed, engine speed, and engine torque. Grille without control parameters can be from vehicles equipped with a standard grille but without active grille control, and may include engine coolant temperature, current fuel consumption, vehicle speed, fan speed, engine speed, and engine torque.

[0062] Understandably, vehicle driving information can be obtained through high-precision maps, such as the vehicle's current altitude and latitude / longitude, as well as the altitude and latitude / longitude at a preset distance ahead of the vehicle.

[0063] It should be understood that the current operating parameters of the vehicle can be obtained through communication between the controller and the vehicle body, and may include parameters such as vehicle speed, fan speed, current engine coolant temperature, engine speed, engine torque, total vehicle weight, and current grille opening value.

[0064] Step S20: Determine the control strategy based on the amount of data of the air intake grille control parameters in the historical driving parameters.

[0065] It's worth noting that since actively controlling the grille intake can reduce vehicle fuel consumption and energy consumption, analyzing the amount of data in historical driving parameters to control the grille opening can make the opening value more precise. At least one preset threshold can be set, and the control strategy can be determined by categorizing the amount of data in the grille control parameters based on this threshold. For example, if the preset threshold is set to 10,000 data points, when the amount of data is less than or equal to 10,000, the grille is controlled based on the impact of the grille opening on the vehicle's engine coolant temperature; when the amount of data is greater than 10,000, the grille is controlled based on the relationship between the grille control parameters and the vehicle's fuel consumption.

[0066] Step S30: Control the opening of the air intake grille based on the control strategy, the historical driving parameters, the vehicle driving information, and the vehicle's current operating parameters.

[0067] Understandably, after determining the control strategy based on the data volume in the above steps, the grille opening can be controlled according to the control strategy and the above parameters. For example, if the amount of data for the obtained grille control parameters is greater than a preset threshold, the grille control parameters in the historical driving parameters are compared with the current vehicle operating parameters to obtain the grille opening value in the historical driving parameters where the current fuel consumption value of the vehicle is equal to the target fuel consumption value. Then, the operating parameters when the vehicle reaches the preset position ahead are determined based on the vehicle driving information, and the grille opening value is further adjusted according to the operating parameters to control the grille opening.

[0068] This embodiment discloses a method for determining a control strategy by acquiring historical driving parameters, vehicle driving information, and current vehicle operating parameters, based on the amount of data for the air intake grille control parameters in the historical driving parameters, and controlling the air intake grille opening based on the control strategy, historical driving parameters, vehicle driving information, and current vehicle operating parameters. Because this embodiment determines the control strategy based on the amount of data for the air intake grille control parameters by acquiring relevant parameters, and then calculates the air intake grille opening based on the control strategy and the aforementioned parameters, it can more accurately control the air intake grille opening. Furthermore, by combining vehicle driving information to calculate and proactively control the air intake grille opening for the next moment, the vehicle system's state is optimized.

[0069] refer to Figure 3 , Figure 3 This is a flowchart illustrating the second embodiment of the air intake grille control method of the present invention.

[0070] Furthermore, considering the impact of actively controlling the air intake grille on reducing vehicle fuel consumption and energy consumption, this embodiment analyzes historical driving parameters based on the amount of data in the air intake grille control parameters to determine the impact of having or not having actively controlling the air intake grille on vehicle energy consumption. Based on this impact, the opening value of the air intake grille is controlled more precisely. Therefore, based on the first embodiment described above, in this embodiment, step S20 includes:

[0071] Step S201: When the data volume of the air intake grille control parameter is in the first data volume range, a preset first strategy is used as the control strategy. The preset first strategy is to control the air intake grille opening based on the influence value of the air intake grille opening on the vehicle engine coolant temperature.

[0072] Understandably, at least two different preset thresholds can be set, and the data can be divided into multiple intervals based on these thresholds. The control strategy is then determined based on the interval containing the data volume. These intervals may or may not overlap. For example, if two preset thresholds are set to 10,000 and 100,000, three non-overlapping intervals can be defined: the first interval is 0 to 10,000, the second interval is 10,000 to 100,000, and the third interval is above 100,000.

[0073] Understandably, the preset first strategy could be to analyze the engine coolant temperature in the historical driving parameters (where there are no control parameters for the air intake grille) to obtain the average coolant temperature, and then compare the current engine coolant temperature in the vehicle's current operating parameters with the average coolant temperature. If it is equal to or higher than the average coolant temperature, the air intake grille opening is increased by a preset degree; if it is lower than the average coolant temperature, the current grille opening value is maintained.

[0074] Step S202: When the data volume of the air intake grille control parameter is in the second data volume range, a preset second strategy is used as the control strategy. The preset second strategy is to control the opening of the air intake grille according to the relationship between the air intake grille control parameter and the vehicle fuel consumption value.

[0075] It is worth noting that the preset second strategy can be to compare the air intake grille control parameters with the vehicle's current operating parameters, select identical data based on the comparison results, use the grille opening value in the identical data as the second air intake grille opening value, and control the air intake grille opening based on the second air intake grille opening value and the vehicle's driving information.

[0076] Furthermore, since the amount of data in the second data range is insufficient, when comparing the air intake grille control parameters with the vehicle's current operating parameters, it is possible that no completely identical data will be found. As an implementation method, in this embodiment, data that meets the similarity conditions is selected as a reference during the comparison. Therefore, step S202 includes: comparing the air intake grille control parameters with the vehicle's current operating parameters, selecting data that meets the first similarity condition based on the comparison result, obtaining a first similar historical parameter list, using the grille opening value corresponding to the first target fuel consumption value from the first similar historical parameter list as the second air intake grille opening value, and controlling the air intake grille opening based on the second air intake grille opening value and the vehicle driving information.

[0077] Understandably, if the vehicle's current operating parameters are "wind speed 8 meters per second, fan speed 2000 revolutions per minute, current fuel consumption 9 liters per 100 kilometers, ..., current grille opening 30 degrees," then the data satisfying the first similarity condition can be those where the difference in wind speed is within 1 meter per second, the difference in fan speed is within 200 revolutions per minute, and the other parameters can also be compared under similar conditions. Therefore, the first similarity historical parameter list could be: Data 1 "wind speed 8 meters per second, fan speed 2120 revolutions per minute, current fuel consumption 8.2 liters per 100 kilometers, ..., grille opening 28 degrees," and Data 2 "wind speed 9 meters per second, fan speed 2100 revolutions per minute, current fuel consumption 8 liters per 100 kilometers, ..., grille opening 32 degrees."

[0078] It is worth noting that the first target fuel consumption value can be the first fuel consumption value selected after sorting the first similar historical parameter list in ascending order according to the current fuel consumption value of the whole vehicle. Then, the grille opening value in the first data is used as the second air intake grille opening value, which is 32 degrees.

[0079] It should be understood that the road information ahead can be analyzed based on information such as the vehicle's current altitude and latitude / longitude, and the altitude and latitude / longitude at a preset distance ahead of the vehicle in the vehicle's driving information. If the road ahead is downhill (slope ≤ -1°), the grille opening value is controlled to 0° in advance, i.e., the air intake grille is closed; if the road ahead is flat (-1° < slope < 1°), the grille opening value is controlled to the second air intake grille opening value, i.e., 32 degrees; if the road ahead is uphill (slope ≥ 1°), the grille opening value is controlled to 90° in advance, i.e., the air intake grille is fully opened.

[0080] Step S203: When the data volume of the air intake grille control parameter is in the third data volume range, the preset third strategy is used as the control strategy. The preset third strategy is to control the opening of the air intake grille according to the air intake grille control parameter, road condition matching and vehicle fuel consumption value.

[0081] It is worth noting that the preset third strategy can be to compare the air intake grille control parameters with the vehicle's current operating parameters, select identical data based on the comparison results, and use the grille opening value in the identical data as the third air intake grille opening value to analyze the vehicle's driving information and obtain the vehicle's forward operating parameters; compare the air intake grille control parameters with the vehicle's forward operating parameters to obtain a forward comparison result, select identical data based on the forward comparison result to obtain a third identical historical parameter list, and use the grille opening value corresponding to the second target fuel consumption value in the third identical historical parameter list as the fourth air intake grille opening value; and control the air intake grille opening according to the third and fourth air intake grille opening values ​​at a preset frequency.

[0082] Furthermore, since the amount of data in the third data range is already sufficient, it is not necessary to fully open or close the air intake grille when there are ups and downs in the road ahead. As an implementation method, in this embodiment, after obtaining the third air intake grille opening value by comparison, the air intake grille opening value is compared again with the air intake grille control parameters based on the road information ahead to obtain a more accurate air intake grille opening value and achieve advance control. Therefore, step S203 includes: comparing the air intake grille control parameters with the vehicle's current operating parameters to obtain a current comparison result; selecting data that meets the second similarity condition based on the current comparison result to obtain a second similarity historical parameter list; and using the grille opening value corresponding to the second target fuel consumption value in the second similarity historical parameter list as the third air intake grille opening value; analyzing the vehicle's driving information to obtain the vehicle's forward operating parameters; comparing the air intake grille control parameters with the vehicle's forward operating parameters to obtain a forward comparison result; selecting data that meets the third similarity condition based on the forward comparison result to obtain a third similarity historical parameter list; and using the grille opening value corresponding to the second target fuel consumption value in the third similarity historical parameter list as the fourth air intake grille opening value; and controlling the air intake grille opening according to the third air intake grille opening value and the fourth air intake grille opening value at a preset frequency.

[0083] Understandably, after analyzing vehicle driving information and obtaining the forward operating parameters, the similarity between the forward operating parameters and the current operating parameters can be determined. If the similarity condition is met, the grille opening is controlled based on the obtained third grille opening value; if the similarity condition is not met, the grille opening value is further determined based on the forward vehicle driving information. For example, if the road ahead is flat and the road conditions remain unchanged, no further adjustment to the grille opening value is needed; if there is a downhill slope ahead, after analyzing the vehicle driving information, it is predicted that the vehicle needs to decelerate, resulting in a decrease in overall fuel consumption. Therefore, parameters such as vehicle speed and current fuel consumption in the current operating parameters are adjusted to obtain the forward operating parameters.

[0084] Of course, the same method of comparing the air intake grille control parameters with the vehicle's current operating parameters can be used to compare the air intake grille control parameters with the vehicle's front operating parameters to obtain the fourth air intake grille opening value, and then control the air intake grille opening according to the fourth air intake grille opening value at a preset frequency.

[0085] In practical implementation, for example, if the vehicle's current operating parameters are "wind speed 8 meters per second, fan speed 2000 revolutions per minute, current fuel consumption 9 liters per 100 kilometers, ...", then the data that meets the second similarity condition can be those where the difference in wind speed is within 1 meter per second, the difference in fan speed is within 200 revolutions per minute, and the other parameters can also be compared under similar conditions. The second similarity historical parameter list could be: Data 1 "wind speed 8 meters per second, fan speed 2120 revolutions per minute, current fuel consumption 8.2 liters per 100 kilometers, ..., grille opening value 28 degrees", and Data 2 "wind speed 9 meters per second, fan speed 2100 revolutions per minute, current fuel consumption 8 liters per 100 kilometers, ..., grille opening value 32 degrees". The second target fuel consumption value can be the first fuel consumption value selected after sorting the second similarity historical parameter list in ascending order according to the current fuel consumption value of the vehicle. The grille opening value in the first data entry would then be used as the third air intake grille opening value, which is 32 degrees. If the obtained vehicle's forward operating parameters are "wind speed 7.8 m / s, fan speed 1800 rpm, current fuel consumption 8.1 liters per 100 km, ...", then the third similar historical parameter list could be: Data 1 "wind speed 7.8 m / s, fan speed 1860 rpm, current fuel consumption 8.0 liters per 100 km, ..., grille opening 25 degrees", and Data 2 "wind speed 7.9 m / s, fan speed 1900 rpm, current fuel consumption 8.3 liters per 100 km, ..., grille opening 24 degrees". Therefore, the fourth air intake grille opening value is 25 degrees, and the air intake grille opening is controlled to 25 degrees in advance according to a 2 Hz frequency.

[0086] In this embodiment, when the data volume of the air intake grille control parameters is in the first data volume range, a preset first strategy is used as the control strategy; when the data volume of the air intake grille control parameters is in the second data volume range, a preset second strategy is used as the control strategy; and when the data volume of the air intake grille control parameters is in the third data volume range, a preset third strategy is used as the control strategy. Because this embodiment divides the data volume of the air intake grille control parameters into three data ranges and formulates corresponding control strategies according to different ranges, it can more accurately control the air intake grille opening by combining vehicle driving information and current vehicle operating parameters with historical driving parameters, and can also perform control in advance by combining road information.

[0087] refer to Figure 4 , Figure 4This is a flowchart illustrating the third embodiment of the air intake grille control method of the present invention.

[0088] Furthermore, vehicles without active grille shutters and vehicles with active grille shutters have different effects on engine coolant temperature when other key parameters and road information are the same. Therefore, this embodiment provides a method to determine the effect of the absence of active grille shutters on engine coolant temperature, so as to calculate the coolant temperature impact value more accurately. Therefore, based on the above second embodiment, in this embodiment, step S201 includes:

[0089] Step S2011: Determine the influence value of the air intake grille opening on the engine coolant temperature of the vehicle based on the no control parameters of the air intake grille in the historical driving parameters and the current operating parameters of the vehicle.

[0090] Understandably, the engine coolant temperature without active control parameters in the historical driving parameters can be used to calculate the median engine coolant temperature to obtain the coolant temperature without active control. Then, based on the current grille opening value, the coolant temperature without active control, and the preset lower limit of coolant temperature in the current vehicle operating parameters, the influence of the grille opening on the vehicle's engine coolant temperature can be determined.

[0091] Furthermore, considering the impact of the grille opening on the vehicle's engine coolant temperature, this embodiment combines the engine coolant temperature without grille control parameters, the current grille opening value, and a preset lower limit for coolant temperature to accurately calculate the impact of the grille opening on the vehicle's engine coolant temperature. Therefore, step S2012 includes: determining the coolant temperature without active control based on the engine coolant temperature without grille control parameters from historical driving parameters, and determining the impact of the grille opening on the vehicle's engine coolant temperature based on the current grille opening value, the coolant temperature without active control, and the preset lower limit for coolant temperature from the vehicle's current operating parameters.

[0092] It is understandable that, based on the historical driving parameters, the engine coolant temperature without control parameters of the air intake grille can be calculated as the average engine coolant temperature, to obtain the coolant temperature T0 without active control. If the preset normal coolant temperature range is T1~T2 (i.e., the preset lower limit of coolant temperature is T1, and the preset upper limit of coolant temperature is T2), and T1≤T0≤T2, the current engine coolant temperature is T3, the current grille opening value is OP0, and 0≤OP0≤90, then the calculation method for the influence value F of the air intake grille opening on the vehicle engine coolant temperature is: F=(90-OP0) / (T0-T1).

[0093] Step S2012: Determine the opening value of the first air intake grille based on the water temperature influence value and the current operating parameters of the vehicle.

[0094] It should be understood that the first air intake grille opening value can be determined based on the temperature difference between the current engine coolant temperature and the preset lower limit of coolant temperature in the vehicle's current operating parameters, the current grille opening value, and the coolant temperature influence value.

[0095] Furthermore, since the opening of the air intake grille has a significant impact on the engine coolant temperature, in order to more accurately calculate the coolant temperature impact value under different air intake grille openings, this embodiment further combines the coolant temperature difference between the current engine coolant temperature and the preset upper limit of coolant temperature in the vehicle's current operating parameters to determine the air intake grille opening value. Therefore, the step of determining the first air intake grille opening value based on the coolant temperature impact value and the vehicle's current operating parameters also includes: determining the first air intake grille opening value based on the coolant temperature difference between the current engine coolant temperature and the preset upper limit of coolant temperature, the current grille opening value, and the coolant temperature impact value in the vehicle's current operating parameters.

[0096] It is worth noting that if the temperature difference between the current engine coolant temperature and the preset upper limit is ΔT, and the opening value of the first air intake grille is OP1, and 0≤OP1≤90, then the method for determining the opening value of the first air intake grille based on the temperature difference between the current engine coolant temperature and the preset upper limit, the current grille opening value, and the coolant temperature influence value in the current vehicle operating parameters is as shown in Table 1:

[0097]

[0098] Table 1

[0099] Step S2013: Control the opening of the air intake grille according to the first air intake grille opening value and the vehicle driving information.

[0100] Understandably, the road information ahead can be analyzed based on information such as the vehicle's current altitude and latitude / longitude, and the altitude and latitude / longitude at a preset distance ahead. If the road ahead is downhill (slope ≤ -1°), the grille opening value is controlled to 0° in advance, i.e., the air intake grille is closed; if the road ahead is flat (-1° < slope < 1°), the grille opening value is controlled to the first air intake grille opening value; if the road ahead is uphill (slope ≥ 1°), the grille opening value is controlled to 90° in advance, i.e., the air intake grille is fully opened.

[0101] In this embodiment, the engine coolant temperature without active control is determined based on the engine coolant temperature without control parameters in the historical driving parameters. The influence of the grille opening on the engine coolant temperature is then determined based on the current grille opening value, the coolant temperature without active control, and the preset lower limit of coolant temperature in the current vehicle operating parameters.
