Description

Technical Field

[0001] The present invention relates to the field of vehicle control technology, and in particular to a control method for a vehicle air conditioner, a computer-readable storage medium, a control device for a vehicle air conditioner, and a vehicle controller. Background Art

[0002] With the continuous advancement of automobile technology and people's increasing requirements for riding comfort, the performance and intelligence of automobile air-conditioning systems, as an important part of improving the riding experience, have become the focus of consumers. When the vehicle is driving in a straight line, the relevant automobile air-conditioning system can better meet the passengers' needs for temperature, humidity and air flow distribution, ensuring the comfort of the in-car environment. However, under the common driving condition of vehicle turning, the relevant air-conditioning system has exposed some significant defects and deficiencies.

[0003] For example, when a vehicle turns, the relative position of the passengers in the vehicle will shift relative to the air outlet due to the adjustment of the vehicle body posture. The relevant air conditioning system often lacks a response mechanism to such dynamic changes, and the airflow direction of the air outlet remains unchanged, causing the airflow that should have been blowing to the passengers to shift. This shift phenomenon is particularly obvious during rapid turns, making the airflow distribution felt by passengers uneven. Some passengers may feel uncomfortable due to the weakened airflow, while others may feel uncomfortable or disturbed due to the excessively strong airflow.

[0004] Secondly, when driving at high speed, the vehicle speed is high and the aerodynamic feel caused by turning is further amplified. Due to the high-speed movement of the vehicle, the flow state of the air in the car is more complex and changeable. It is difficult for the relevant air-conditioning system to accurately predict and adjust the airflow direction of the air outlet to adapt to this rapidly changing environment. This not only affects the passengers' comfort experience, but may also reduce the energy efficiency of the air-conditioning system to a certain extent and increase energy consumption. Summary of the invention

[0005] The present invention aims to solve at least one of the technical problems in the related art to a certain extent. To this end, the first object of the present invention is to propose a control method for a vehicle air conditioner, which can significantly improve the uniformity of air flow distribution in the vehicle, optimize the driving experience of the driver and passengers, and effectively improve the energy efficiency of the air conditioning system.

[0006] A second objective of the present invention is to provide a computer-readable storage module.

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The following describes a vehicle air conditioning control method, a computer-readable storage medium, a vehicle air conditioning control device, and a vehicle according to embodiments of the present invention with reference to the accompanying drawings.

[0034] Figure 1 1 is a flow chart of a method for controlling a vehicle air conditioner according to an embodiment of the present invention.

[0035] Specifically, in some embodiments of the present invention, Figure 1 As shown, the control method of the vehicle air conditioner includes:

[0036] S101, acquiring air conditioner operation data and vehicle operation data.

[0037] Specifically, in this embodiment, the vehicle operation data includes the vehicle's steering wheel steering acceleration, the angle ratio between the steering wheel and the wheel, and the driving speed. A steering acceleration sensor can be installed on the steering wheel, and the vehicle's steering wheel steering acceleration can be obtained through the steering acceleration sensor. An angle sensor can be installed on the steering wheel and the wheel, and the system can calculate the ratio between the steering wheel rotation angle and the wheel rotation angle. A speed sensor is installed on the vehicle, and the driving speed can be obtained through the speed sensor. The air conditioner operation data includes the air outlet speed of the air conditioner, the current air outlet angle, and the target air supply position. A wind speed sensor and an air outlet angle sensor can be installed on the air conditioner, and the air outlet speed of the air conditioner can be obtained through the wind speed sensor, and the current air outlet angle can be obtained through the air outlet angle sensor. The target air supply position can be set through an interface such as a remote control, a control panel, or a smart phone application of the air conditioner. In addition, the present invention may not specifically limit the method for obtaining air conditioner operation data and vehicle operation data.

[0038] S102, when it is determined according to the vehicle operation data that the vehicle is in a turning state, calculating a target air outlet angle of the air conditioner according to the air conditioner operation data and the vehicle operation data.

[0039] Specifically, in this embodiment, the vehicle operation data includes the steering wheel acceleration of the vehicle. When the steering wheel acceleration of the vehicle is greater than the preset acceleration, it is determined that the vehicle is in a steering condition, and the target air outlet angle of the air conditioner can be calculated according to the operation data of the air conditioner and the vehicle data, wherein the vehicle operation data also includes the angle ratio between the steering wheel and the wheel and the driving speed, and the air conditioner operation data includes the air outlet speed of the air conditioner, the current air outlet angle and the target air supply position. In a specific example, the target air outlet angle of the air conditioner can be calculated according to the following formula:

[0040] cos(θadjust)=Astreeer*[(Bstreer-Wheel) / Vcar]*(1-e-θcurrent*Vcar / (Vair*(Doutlet–Target))*1 / Astreer*(Bstreer-Wheel))

[0041] Among them, θadjust represents the target air outlet angle, Astreer represents the steering wheel steering acceleration, Bstreer-Wheel represents the angle ratio between the steering wheel and the wheel, Vcar represents the driving speed, θcurrent represents the current air outlet angle, Vair represents the air outlet speed, and Doutlet–Target represents the distance between the air outlet of the air conditioner and the target air supply position.

[0042] In addition, the present invention may not specifically limit the method of calculating the target air outlet angle of the air conditioner. For example, a preset table may be queried based on the operating data of the air conditioner and the vehicle data to determine the target air outlet angle of the air conditioner.

[0043] S103: adjusting the air outlet angle of the air conditioner according to the target air outlet angle.

[0044] Specifically, in this embodiment, after the target air outlet angle of the air conditioner is calculated based on the air conditioner operating data and the vehicle operating data, an adjustment instruction can be sent to the air conditioner to control the mechanical components on the air conditioner (such as air guide plates, air outlet adjustment mechanisms, etc.), thereby adjusting the air outlet angle of the air conditioner so that the air outlet angle gradually approaches or reaches the target air outlet angle. In addition, after the adjustment is completed, sensors or other detection means can be used to verify whether the actual air outlet angle of the air conditioner is consistent with the target air outlet angle. No specific limitation is made here. If there is a deviation, adjustment is made again until the target air outlet angle is reached.

[0045] Further, in some embodiments of the present invention, when the steering wheel steering acceleration is greater than a preset acceleration, it is determined that the vehicle is in a turning state; when the steering wheel steering acceleration is less than or equal to the preset acceleration, it is determined that the vehicle is in a straight-moving state.

[0046] Specifically, in this embodiment, the steering wheel steering acceleration can be obtained by a steering acceleration sensor arranged on the steering wheel. When the steering wheel steering acceleration is greater than a preset acceleration, it is determined that the vehicle is in a steering state. When the steering wheel steering acceleration is less than or equal to the preset acceleration, it is determined that the vehicle is in a straight-moving state. The preset acceleration can preferably be 0.5 radians per square second. In addition, the present invention may not specifically limit the value of the preset acceleration.

[0047] Furthermore, in some embodiments of the present invention, when the vehicle changes from a turning state to a straight-moving state, the target air outlet angle of the air conditioner is determined to be zero degrees.

[0048] Specifically, in this embodiment, when the vehicle changes from a turning state to a straight state, the target air outlet angle of the air conditioner is determined to be zero degrees. At this time, an adjustment instruction can be sent to the air conditioner to control the mechanical components (such as air guide plates, air outlet adjustment mechanisms, etc.) on the air conditioner, so as to adjust the air outlet angle of the air conditioner so that the air outlet angle gradually returns to zero degrees. In addition, after the adjustment is completed, a sensor or other detection means can be used to verify whether the actual air outlet angle of the air conditioner is consistent with the target air outlet angle, which is not specifically limited here. If there is a deviation, it is adjusted again until the target air outlet angle is reached. This optimizes the driving experience of the driver and passengers and effectively improves the energy efficiency of the air conditioning system.

[0049] Furthermore, in some embodiments of the present invention, the air outlet angle of the air conditioner is adjusted according to the target air outlet angle, including: performing multiple fine-adjustments on the air outlet angle of the air conditioner according to the target air outlet angle, so that the air outlet angle of the air conditioner reaches the target air outlet angle after multiple fine-adjustments, wherein the air conditioner performs the next fine-adjustment at an interval of a preset time after performing one fine-adjustment.

[0050] Specifically, in this embodiment, after the target air outlet angle of the air conditioner is calculated according to the air conditioner operation data and the vehicle operation data, the air outlet angle of the air conditioner can be fine-tuned multiple times according to the target air outlet angle. For example, when the angle to be adjusted is 20 degrees, the system can divide 20 degrees into four 5-degree intervals for four fine-tunings, and after each adjustment of 5 degrees, a smooth transition is performed at intervals of a preset time, wherein the preset time can be preferably 0.5 seconds, thereby ensuring that the driver and passengers will not feel the airflow deviation due to turning, thereby improving the driving experience of the driver and passengers. In addition, the present invention may not specifically limit the value of the preset time.

[0051] Furthermore, in some embodiments of the present invention, the air outlet angle of the air conditioner is adjusted according to the target air outlet angle, including: performing multiple fine-adjustments on the air outlet angle of the air conditioner according to the target air outlet angle, and obtaining the air outlet angle of the air conditioner after each fine-adjustment, until the difference between the air outlet angle of the air conditioner and the target air outlet angle is less than or equal to a preset angle.

[0052] Specifically, in this embodiment, after the target air outlet angle of the air conditioner is calculated according to the air conditioner operation data and the vehicle operation data, the air outlet angle of the air conditioner can be fine-tuned multiple times according to the target air outlet angle until the difference between the air outlet angle of the air conditioner and the target air outlet angle is less than or equal to the preset angle. For example, the target air outlet angle is 20 degrees, the initial air outlet angle of the air conditioner is 5 degrees, the preset angle can be preferably ±3 degrees, and the degree of each fine adjustment is 4 degrees. After three fine adjustments, the air outlet angle of the air conditioner is 17 degrees. At this time, the difference between the air outlet angle of the air conditioner and the target air outlet angle is less than or equal to the preset angle, and it is determined that the adjustment of the air conditioner is completed. In addition, the present invention may not specifically limit the value of the preset angle.

[0053] Furthermore, in some embodiments of the present invention, the vehicle includes a front air conditioner and a rear air conditioner, and when the vehicle is in a turning state, the air outlet adjustment angle of the front air conditioner is greater than the air outlet adjustment angle of the rear air conditioner.

[0054] Specifically, in this embodiment, the vehicle includes a front air conditioner and a rear air conditioner, both of which are equipped with an intelligent wind direction adjustment system. When the vehicle is in a turning state, the air outlet adjustment angle of the front air conditioner is greater than the air outlet adjustment angle of the rear air conditioner. For example, when the vehicle is driving at a speed of 60km / h on a rural road and turns left, the system first detects that the position of the front passenger is relatively stable, but considering that the vehicle turns to the left, in order to avoid the airflow from deviating from the passenger's body due to the turn, the air outlet of the front air conditioner will automatically adjust the angle by about 10° to ensure that the airflow can still blow accurately to the passenger. At the same time, for the rear passengers, since they are far away from the air outlet, the system will adjust the air outlet angle of the rear air conditioner by about 5° after calculation to reduce the impact of the turn on the rear airflow, so that the rear passengers will not feel the airflow deviating due to the turn, thereby improving the comfort of the passengers.

[0055] In a specific embodiment of the present invention, Figure 2As shown, data collection is first performed to obtain air conditioner operation data and vehicle operation data. When it is determined that the vehicle is in a turning state according to the vehicle operation data, the target air outlet angle of the air conditioner is calculated according to the air conditioner operation data and the vehicle operation data, and it is determined whether the air outlet angle needs to be adjusted according to the target air outlet angle. For example, when the difference between the air outlet angle of the air conditioner and the target air outlet angle is less than or equal to the preset angle, it is determined that the air outlet angle of the air conditioner does not need to be adjusted, and the air conditioner operation data and the vehicle operation data are continuously obtained to perform data monitoring and calculation. Otherwise, the air outlet angle of the air conditioner is adjusted according to the target air outlet angle, and when the vehicle changes from a turning state to a straight state, the target air outlet angle of the air conditioner is determined to be zero degrees. An adjustment instruction can be sent to the air conditioner to control the mechanical components (such as an air guide plate, an air outlet adjustment mechanism, etc.) on the air conditioner, so as to adjust the air outlet angle of the air conditioner so that the air outlet angle gradually returns to zero degrees. In addition, if the initial air outlet angle is three degrees when the vehicle is in a straight-moving state, then when the vehicle changes from a turning state to a straight-moving state, the target air outlet angle of the air conditioner is determined to be three degrees.

[0056] In summary, according to the control method of the vehicle air conditioner in an embodiment of the present invention, by obtaining the air conditioner operating data and the vehicle operating data, and when it is determined according to the vehicle operating data that the vehicle is in a turning state, the target air outlet angle of the air conditioner is calculated according to the air conditioner operating data and the vehicle operating data, so as to adjust the air outlet angle of the air conditioner according to the target air outlet angle. As a result, the uniformity of the air flow distribution in the vehicle can be significantly improved, the driving experience of the driver and passengers can be optimized, and the energy efficiency of the air conditioning system can be effectively improved.

[0057] Based on the control method of the vehicle air conditioner proposed in the aforementioned embodiment of the present invention, the embodiment of the present invention also proposes a computer-readable storage module, on which a control program of the vehicle air conditioner is stored. When the control program of the vehicle air conditioner is executed by the processor, the control method of the vehicle air conditioner of the aforementioned embodiment of the present invention is implemented.

[0058] According to the computer-readable storage medium of an embodiment of the present invention, by executing the control program of the vehicle air conditioner through the processor, the uniformity of the air flow distribution in the vehicle can be significantly improved, the driving experience of the driver and passengers can be optimized, and the energy efficiency of the air conditioning system can be effectively improved.

[0070] In some embodiments of the present invention, the vehicle includes a front air conditioner and a rear air conditioner, and when the vehicle is in a turning state, the air outlet adjustment angle of the front air conditioner is greater than the air outlet adjustment angle of the rear air conditioner.
