[0026] Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings.

[0027] An embodiment of the present application provides a vehicle, including an air conditioner and a control device for the vehicle air conditioner. The control device for the vehicle air conditioner includes one or more processors for implementing air conditioner air outlet parameter control. The air outlet parameters here include at least one of the air outlet direction and the air outlet volume. In some embodiments, the air conditioner includes a control device for the vehicle air conditioner. In some embodiments, the control device for the vehicle air conditioner is electrically connected to the air conditioner and does not belong to the air conditioner. For example, part of the existing control system of the air conditioner itself can be configured, such as configuring rules for the CCM (Chassis Control Module, vehicle stability control system) as the control device for the vehicle air conditioner here.

[0028] Specifically, the air conditioner includes an air outlet grille and an air outlet grille motor electrically connected to the air outlet grille, and the air outlet grille motor is electrically connected to the control device of the vehicle air conditioner. By controlling the air outlet grille motor, the angle of the air outlet grille can be controlled, thereby controlling the air outlet direction of the air conditioner.

[0029] The air conditioner includes a fan, and in some embodiments, the fan is electrically connected to the control device of the vehicle air conditioner, and the air volume of the air conditioner is adjusted by adjusting the fan speed. In some embodiments, the air conditioner includes an air duct adjustment device, and the air duct adjustment device is electrically connected to the control device of the vehicle air conditioner, and the air volume of the air conditioner is adjusted by adjusting the air duct adjustment device. The air duct adjustment device is, for example, an air volume adjustment valve, an air flow distribution device, etc., arranged in the air supply duct of the air conditioner.

[0030] Combination Figure 1 As shown, an embodiment of the present application provides a vehicle air-conditioning control method, which is applied to the aforementioned vehicle air-conditioning control device. The vehicle air-conditioning control method includes steps S11 to S13.

[0031] Step S11, obtaining movement information for characterizing vehicle acceleration.

[0032] Step S12, determining an air outlet compensation strategy of the air conditioner according to the movement information. Step S13, adjusting the air outlet parameters of the air conditioner according to the air outlet compensation strategy. The air outlet parameters include at least one of the air outlet direction and the air outlet volume.

[0033] By adopting the vehicle air-conditioning control method provided in the embodiment of the present application, movement information that can characterize the vehicle acceleration is obtained, and the air outlet compensation strategy of the air-conditioning is determined based on the movement information. At least one of the air outlet direction and the air volume of the air-conditioning can be adjusted according to the actual change of the vehicle acceleration during the driving process of the vehicle. In the air-conditioning control process, the impact of the driving state change on the air outlet of the air-conditioning is taken into account, which is beneficial to improving the accuracy of the air outlet control of the air-conditioning in the vehicle, thereby optimizing the user experience of the passengers in the vehicle.

[0034] Taking into account that the acceleration of the vehicle in different directions will have different effects on the air outlet of the air conditioner, the corresponding air outlet compensation strategy will change accordingly. The following is a specific description of the process of ultimately adjusting the air outlet parameters of the air conditioner based on the movement information.

[0035] Combination Figure 2 As shown, the embodiment of the present application provides another method for controlling a vehicle air conditioner, including steps S111 to S131.

[0036] Step S111, obtaining movement information for characterizing the acceleration of the vehicle. The movement information is used to characterize the acceleration of the vehicle along a first direction, as the first acceleration, and the first direction is parallel to the rotation axis direction of the vehicle tire. Figure 3 is the top view of the vehicle, where the first direction is Figure 3 The x-axis is shown.

[0037] Here is an explanation of the optional implementation method for obtaining the mobile information:

[0038] In some embodiments, the vehicle includes an acceleration sensor, and obtaining movement information for characterizing the acceleration of the vehicle includes: obtaining the acceleration of the vehicle along a first direction through the acceleration sensor.

[0039] In some embodiments, the vehicle includes an angular velocity sensor for measuring the angular velocity of the vehicle. The angular velocity sensor is electrically connected to a control device of the vehicle air conditioner. The control device determines the acceleration of the vehicle along the first direction according to the angular velocity of the vehicle.

[0040] In some embodiments, obtaining movement information for characterizing vehicle acceleration includes: obtaining the center of gravity position of the vehicle and determining a change in the center of gravity position. Figure 4 It is a schematic diagram of the moving trajectory of the center of gravity. The change of the center of gravity of the vehicle can be determined according to the moving trajectory of the center of gravity, and the change of the center of gravity can reflect the acceleration of the vehicle. For example, if the vehicle accelerates along the first direction to the right side of the vehicle, the center of gravity of the vehicle shifts to the left. If the vehicle accelerates along the first direction to the left side of the vehicle, the center of gravity of the vehicle shifts to the right. In this way, the acceleration of the vehicle can be accurately characterized according to the center of gravity of the vehicle.

[0041] In some embodiments, obtaining movement information for characterizing vehicle acceleration includes: obtaining changes in the steering angle of the steering wheel of the vehicle during vehicle driving. Specifically, the change in the steering wheel steering angle here is the rate of change of the steering wheel steering angle. For example, the acceleration of the vehicle in a first direction is represented by the change in the steering wheel steering angle in adjacent unit times. If the steering wheel rotates in the same direction in adjacent unit times and the change in the steering wheel steering angle increases, it means that the rate of change of the steering wheel steering angle in the current direction increases, and the acceleration of the vehicle in the first direction points to the side corresponding to the current steering wheel rotation direction, and the absolute value of the acceleration is positively correlated with the rate of change of the steering wheel. In this way, the acceleration of the vehicle can be accurately characterized by only monitoring the steering angle of the steering wheel.

[0042] Step S121: determining a first compensation angle of the air outlet grille along a first direction according to the first acceleration.

[0043] During the implementation process, it is necessary to pre-set the correspondence between the first acceleration and the first compensation angle to determine the first compensation angle corresponding to the current first acceleration. In some embodiments, the correspondence can be expressed in the form of a mapping relationship between numerical values, and the first compensation angle corresponding to the current first acceleration can be directly called. This is conducive to simplifying the calculation process in actual use and saving computing power. In some embodiments, the correspondence can be expressed in the form of a formula, with the first acceleration as the independent variable and the first compensation angle as the dependent variable. The first compensation angle can be calculated in real time based on the current first acceleration and the formula. In this way, while accurately determining the first compensation angle, there is no need to store a large amount of data.

[0044] Step S131, adjusting the air outlet grille according to the first compensation angle to adjust the air outlet direction of the air conditioner. Specifically, the air outlet grille is adjusted by controlling the air outlet grille motor.

[0045] During vehicle turning and U-turning, acceleration in the first direction is easily generated, and the air conditioning outlet is delayed relative to the movement of the vehicle interior. For example, when the vehicle is accelerating to the right, the wind blown out from the air conditioning outlet grille cannot completely follow the vehicle's acceleration to the right, causing the air conditioning outlet to be biased to the left. For the occupants, the actual air outlet direction of the air conditioner does not match the target air outlet direction, causing a temperature change in the body, affecting the user experience. Therefore, adjusting the air outlet direction of the air conditioner according to the acceleration of the vehicle in the first direction is conducive to improving the accuracy of the air conditioning outlet control during vehicle driving, and optimizing the occupant experience during vehicle driving, especially during vehicle turning and U-turning.

[0046] Specifically, the relationship between the first compensation angle and the first acceleration is: the first compensation angle is in the same direction as the first acceleration, and the absolute value of the first compensation angle is positively correlated with the absolute value of the first acceleration. That is, if the current first acceleration is to the right, that is, the vehicle accelerates to the right, then the first compensation angle also increases to the right. And the larger the value of the first acceleration, the larger the first compensation angle. Combined with the above analysis of the air-conditioning outlet deviation, it can be seen that when the first acceleration is to the right, the air-conditioning outlet is biased to the left. On this basis, adjusting the air outlet grille so that the air-conditioning outlet direction is adjusted to the right is conducive to counteracting the deviation between the air-conditioning outlet and the target outlet direction, so that the actual air outlet of the air conditioner is more in line with the target outlet direction, thereby improving the accuracy of the air-conditioning outlet control, and then improving the experience of the passengers in the vehicle.

[0047] Specifically, in some embodiments, adjusting the air outlet grille according to the first compensation angle includes: taking the angle of the air outlet grille along the first direction when the first acceleration is 0 as the first reference angle; determining the first target angle according to the sum of the first reference angle and the first compensation angle; and adjusting the air outlet grille along the first direction to the first target angle. In the process of determining the first compensation angle according to the first acceleration, the case where the first acceleration is 0 is actually used as a comparison. Correspondingly, the target angle is determined based on the first reference angle of the air outlet grille when the first acceleration is 0 to adjust the air outlet grille, which is conducive to achieving accurate control of the air outlet direction.

[0048] Further, in some embodiments, determining the first target angle according to the sum of the first reference angle and the first compensation angle includes: calculating the sum of the first reference angle and the first compensation angle as the first sum. Obtaining the angular range of motion of the air outlet grille in the first direction as the first angle interval. When the first sum belongs to the first angle interval, determining the first sum as the first target angle; when the first sum does not belong to the first angle interval, determining the angle value closest to the first sum in the first angle interval as the first target angle. Considering the hardware limitation, it is necessary to verify the feasibility of the sum of the first reference angle and the first compensation angle. If the first sum does not belong to the angular range of motion that can be achieved by the air outlet grille in the first direction, it means that the first sum is not actually feasible, so the feasible angle value closest to the first sum is selected as the first target angle to achieve the most accurate control of the air outlet angle of the air conditioner.

[0049] During the implementation process, since the angle change of the air outlet grille is actually achieved through the control of the air outlet grille motor, after determining the first target angle, the motor operation step corresponding to the air outlet grille angle to be adjusted is determined according to the motor operation characteristic curve of the air outlet grille motor, which is used to control the air outlet grille motor.

[0050] In some embodiments, the control method further includes: determining the compensation step length of the air outlet grille motor according to the first compensation angle. Specifically, the air outlet grille angle to be adjusted is determined according to the first target angle and the current air outlet grille angle, and the compensation step length of the air outlet grille motor is positively correlated with the air outlet grille angle to be adjusted. That is, the larger the air outlet grille angle to be adjusted, the faster the adjustment process of the air outlet grille. In this way, on the one hand, when the air outlet grille angle to be adjusted is large, the air outlet grille can be adjusted to the first target angle more quickly, and the adjustment of the air outlet direction of the air conditioner can be completed in a shorter time, avoiding the situation where the adjustment is too delayed. On the other hand, when the air outlet grille angle to be adjusted is small, the air outlet grille angle is avoided to be adjusted too quickly, resulting in excessive adjustment and the like, which is conducive to improving the accuracy of the air outlet grille adjustment, thereby improving the accuracy of the air outlet direction control of the air conditioner.

[0051] Combination Figure 5 As shown, the embodiment of the present application provides another method for controlling a vehicle air conditioner, including steps S112 to S132.

[0052] Step S112, obtaining movement information for characterizing the vehicle acceleration.

[0053] Here, the movement information is used to characterize the acceleration of the vehicle along the second direction, which is parallel to the wheelbase direction of the vehicle. The wheelbase is the distance between the front axle and the rear axle of the vehicle. Figure 3 As shown, the second direction here is the y-axis direction, that is, the body direction of the vehicle when it is moving straight.

[0054] During implementation, similar to the above-mentioned method for obtaining the angular velocity for representing the vehicle in the first direction, the second acceleration of the vehicle in the second direction can be directly determined by an acceleration sensor, or the second acceleration can be represented by the change in the center of gravity of the vehicle. In other embodiments, the second acceleration can also be determined by a speed sensor monitoring the speed and then calculating the speed.

[0055] Step S122, determining the compensation air volume according to the second acceleration of the vehicle.

[0056] During the implementation process, it is necessary to pre-set the correspondence between the second acceleration and the compensation air volume to determine the compensation air volume corresponding to the current second acceleration. In some embodiments, the correspondence can be expressed in the form of a mapping relationship between numerical values, and the corresponding compensation air volume can be directly called according to the current second acceleration. This is conducive to simplifying the calculation process in actual use and saving computing power. In some embodiments, the correspondence can be expressed in the form of a formula, with the second acceleration as the independent variable and the compensation air volume as the dependent variable. The compensation air volume can be calculated in real time according to the current second acceleration and the formula. In this way, while accurately determining the compensation air volume, there is no need to store a large amount of data.

[0057] Step S132, adjusting the air volume of the air conditioner according to the compensation air volume.

[0058] During the driving process of the vehicle, acceleration in the second direction is generated, such as the acceleration and deceleration process of the vehicle in the straight-line process. For example, with the same air volume, if the current vehicle accelerates forward, that is, the second acceleration points to the front of the vehicle, with the air outlet of the air conditioner as a reference, the distance between the occupant and the air outlet grille is smaller, and the perceived air outlet intensity is greater, which does not match the target situation, causing discomfort to the occupant. Therefore, adjusting the air volume of the air conditioner according to the second acceleration of the vehicle in the second direction during the driving process of the vehicle is conducive to improving the accuracy of the air volume control of the air conditioner and optimizing the occupant experience.

[0059] Among them, the compensation air volume is determined according to the second acceleration of the vehicle, including: when the direction of the second acceleration is in front of the vehicle's driving direction, the compensation air volume is determined to be a negative value; when the direction of the second acceleration is behind the vehicle's driving direction, the compensation air volume is determined to be a positive value. And, the absolute value of the compensation air volume is determined to be positively correlated with the absolute value of the second acceleration. When the direction of the second acceleration is in front of the vehicle's driving direction, for example, when the vehicle accelerates forward during straight driving, the wind intensity felt by the user is greater than the target situation. At this time, the compensation air volume is determined to be a negative value, that is, the compensation air volume is reduced, which is conducive to counteracting the situation where the air volume of the air conditioner is too large, so that the passenger's body feels closer to the target situation. The situation where the direction of the second acceleration is behind the vehicle's driving direction is the opposite, which can counteract the situation where the wind intensity felt by the user is smaller than the target situation, avoid insufficient air supply distance of the air conditioner, and thus help improve the accuracy of the air volume control of the air conditioner and optimize the control of the air volume of the air conditioner. Determining that the absolute value of the compensation air volume is positively correlated with the absolute value of the second acceleration is conducive to further improving the accuracy of the compensation air volume control.

[0060] It should be noted that the process of adjusting the air volume of the air conditioner according to the compensation air volume here takes the case where the second acceleration is 0 as the adjustment reference. Specifically, adjusting the air volume of the air conditioner according to the compensation air volume includes: taking the air volume of the air conditioner as the reference air volume when the second acceleration is 0; determining the target air volume according to the sum of the reference air volume and the compensation air volume; and adjusting the air volume of the air conditioner to the target air volume. Further, considering that the actual implementable air volume range is limited, the feasibility of the target air volume is verified. In some embodiments, determining the target air volume according to the sum of the reference air volume and the compensation air volume includes: calculating the sum of the reference air volume and the compensation air volume; and obtaining the air volume range of the air conditioner. When the sum of the reference air volume and the compensation air volume belongs to the air volume range, the sum of the reference air volume and the compensation air volume is used as the target air volume. When the sum of the reference air volume and the compensation air volume does not belong to the air volume range, the air volume closest to the sum in the air volume range is used as the target air volume. In this way, accurate control of the air volume of the air conditioner can be achieved.

[0061] Combination Figure 6 As shown, the embodiment of the present application provides another method for controlling a vehicle air conditioner, including steps S113 to S133.

[0062] Step S113, obtaining movement information for characterizing the vehicle acceleration.

[0063] Here, the movement information is used to characterize the acceleration of the vehicle along the third direction. As the third acceleration, the third direction is perpendicular to the rotation axis direction of the tire of the vehicle and perpendicular to the wheelbase direction of the vehicle body. Figure 3 The plane where the x-axis and y-axis are located. The third acceleration can reflect the change in the speed of the vehicle in the vertical direction, which is applicable to the vehicle going uphill and downhill. During implementation, the third acceleration of the vehicle along the third direction can be directly determined by the acceleration sensor, and the third acceleration can also be represented by the change in the center of gravity position of the vehicle. In other embodiments, the acceleration in the third direction can also be determined by a slope sensor combined with a speed sensor.

[0064] Step S123: determining a second compensation angle of the air outlet grille along a third direction according to the third acceleration.

[0065] Step S133, adjusting the air outlet grille according to the second compensation angle to adjust the air outlet direction of the air conditioner.

[0066] Similar to the impact caused by the first acceleration, the third acceleration of the vehicle in the third direction will also cause the actual air outlet angle to be inconsistent with the target air outlet angle. For example, if the third acceleration of the vehicle points upward, such as when accelerating uphill, with the passengers as a reference, the actual air outlet angle of the air conditioner will be offset downward compared to the target air outlet angle, causing a perceived temperature and discomfort to the occupants. Therefore, adjusting the air outlet direction of the air conditioner according to the acceleration of the vehicle in the third direction is conducive to improving the accuracy of the air conditioner air outlet control.

[0067] Among them, the second compensation angle is in the same direction as the third acceleration, and the absolute value of the second compensation angle is positively correlated with the absolute value of the third acceleration. That is, if the current third acceleration is upward, that is, the vehicle accelerates upward, then the third compensation angle also increases upward. And the larger the value of the third acceleration, the larger the third compensation angle. Combined with the above analysis of the air-conditioning outlet deviation, it can be seen that when the third acceleration is upward, the air-conditioning outlet is biased downward. On this basis, adjusting the air outlet grille so that the air-conditioning outlet direction is adjusted upward is conducive to counteracting the deviation between the air-conditioning outlet and the target outlet direction, so that the actual air outlet of the air conditioner is more in line with the target outlet direction, thereby improving the accuracy of the air-conditioning outlet control, and then improving the experience of the passengers in the vehicle.

[0068] Specifically, in some embodiments, adjusting the air outlet grille according to the second compensation angle includes: taking the angle of the air outlet grille along the third direction when the third acceleration is 0 as the second reference angle; determining the second target angle according to the sum of the second reference angle and the second compensation angle; and adjusting the air outlet grille along the third direction to the second target angle. In the process of determining the second compensation angle according to the third acceleration, the case where the third acceleration is 0 is actually used as a comparison. Correspondingly, the target angle is determined based on the second reference angle of the air outlet grille when the third acceleration is 0 to adjust the air outlet grille, which is conducive to achieving accurate control of the air outlet direction.

[0069] Further, in some embodiments, the second target angle is determined according to the sum of the second reference angle and the second compensation angle, including: calculating the sum of the second reference angle and the second compensation angle as the second sum; obtaining the angular range of the air outlet grille in the third direction as the second angle interval; when the second sum belongs to the second angle interval, determining the second sum as the second target angle; when the second sum does not belong to the second angle interval, determining the angle value closest to the second sum in the second angle interval as the second target angle. Considering the hardware limitation, it is necessary to verify the feasibility of the sum of the second reference angle and the second compensation angle. If the third sum does not belong to the angular range of the air outlet grille that can be achieved in the third direction, it means that the third sum is not actually feasible, so the feasible angle value closest to the third sum is selected as the second target angle to achieve the most accurate control of the air outlet angle of the air conditioner.

[0070] During the implementation process, since the angle change of the air outlet grille is actually achieved through the control of the air outlet grille motor, after determining the second target angle, the motor operation step corresponding to the air outlet grille angle to be adjusted is determined according to the motor operation characteristic curve of the air outlet grille motor, which is used to control the air outlet grille motor.

[0071] In some embodiments, the control method further includes: determining the compensation step size of the air outlet grille motor according to the second compensation angle. Specifically, the air outlet grille angle to be adjusted is determined according to the second target angle and the current air outlet grille angle, and the compensation step size of the air outlet grille motor is positively correlated with the air outlet grille angle to be adjusted. That is, the larger the air outlet grille angle to be adjusted, the faster the adjustment process of the air outlet grille. In this way, on the one hand, when the air outlet grille angle to be adjusted is large, the air outlet grille can be adjusted to the second target angle more quickly, and the adjustment of the air outlet direction of the air conditioner can be completed in a shorter time, avoiding the situation where the adjustment is too delayed. On the other hand, when the air outlet grille angle to be adjusted is small, the air outlet grille angle is avoided to be adjusted too quickly, resulting in excessive adjustment and the like, which is conducive to improving the accuracy of the air outlet grille adjustment, thereby improving the accuracy of the air outlet grille control.

[0072] In some embodiments, determining the air outlet compensation strategy of the air conditioner according to the movement information includes: when the movement information indicates that the vehicle acceleration is greater than the acceleration threshold, determining the air outlet compensation strategy of the air conditioner according to the movement information. In this way, the triggering conditions for the process of determining the air outlet compensation strategy are set to avoid adjusting the air outlet parameters of the air conditioner when the acceleration is small and has almost no impact on the user experience. Avoid frequent triggering of the air outlet compensation strategy, which leads to waste of resources and wear of components. In combination with the foregoing embodiments, it can be seen that in the process of determining the air outlet compensation strategy of the air conditioner according to the movement information, the adjustment of different dimensions of the air conditioner can be achieved through the acceleration in the first direction, the second direction and the third direction. Correspondingly, the corresponding acceleration thresholds are set for different directions, which can be set according to actual needs, and there is no restriction on the specific values ​​here.
