Description

Technical Field

[0001] The present application relates to the technical field of vehicle accessory control, and particularly to an active intake grille control method, device, electronic device and vehicle. Background Art

[0002] The intake grille is the channel entrance for air to flow into the vehicle engine compartment. It includes multiple vanes. When the opening degrees of the vanes are different, the opening size of the channel entrance is changed, so that the air flow is different. If the ventilation area of the intake grille is large, the wind resistance of the vehicle will increase, affecting the energy use efficiency of the vehicle; if the ventilation area of the intake grille is too small, the cooling performance of the whole vehicle and the air-conditioning comfort will be affected. Therefore, some vehicles adopt an active intake grille (AGS: Active Grille Shutter), which can automatically control the vane angle of the active intake grille.

[0003] In the existing control scheme of the active intake grille, a transmission mechanism is used to drive the vanes to rotate. During the driving process of the vehicle, the vehicle controller can determine the air flow according to the vehicle speed and the temperature inside the vehicle, calculate the desired angle, and thus control the transmission mechanism to drive the vanes to rotate, aiming to control the vanes to rotate to the calculated desired angle. However, during the actual driving process of the vehicle, the vane opening degree of the active intake grille will be affected by environmental factors. For example, if there is wind in the vehicle driving environment, the vane angle change will be affected by the wind speed. Therefore, the result of controlling the vane angle adjustment by the transmission mechanism will be different from the expected result, affecting the control accuracy of the active intake grille.

[0040] The following further describes the detailed embodiments of this application with reference to the drawings.

[0041] It is easily understood that according to the technical solution of the present application, under the condition of not changing the essential spirit of the present application, there are various structural ways and implementation ways that can be mutually replaced by those of ordinary skill in the art. Therefore, the following specific embodiments and the accompanying drawings are only exemplary descriptions of the technical solution of the present application, and should not be regarded as all of the present application or as a limitation or restriction on the technical solution of the application.

[0042] The orientation terms such as up, down, left, right, front, back, front side, back side, top, bottom, etc. mentioned or possibly mentioned in this specification are defined relative to the structures shown in the respective drawings. They are relative concepts, and thus may change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be construed as restrictive terms.

[0043] The embodiment of the present application provides an active intake grille control method, which can be applied to the vehicle's vehicle controller, such as Figure 1 as shown, the method includes the following steps:

[0044] S10: Obtain the desired angle of the active intake grille blades, where the desired angle is the blade angle matching the vehicle driving speed and the temperature inside the vehicle cabin.

[0045] The vehicle controller can obtain the desired angle by using existing solutions. For example, during the vehicle driving process, the vehicle driving speed and the temperature inside the vehicle cabin are obtained. Considering the balance between the vehicle wind resistance and the overall vehicle cooling performance and air conditioning comfort, the desired angle can be determined. The balance requirements can be determined by calibration tests and other methods before the vehicle leaves the factory.

[0046] S20: Obtain the actual angle of the active intake grille blades. If the actual angle is different from the desired angle, control the active intake grille blades to rotate until the actual angle is the same as the desired angle, and then control the active intake grille blades to stop rotating.

[0047] In specific implementation, the actual angle of the active intake grille blades can be detected by an angle sensor set on the blade rotating shaft of the active intake grille. Other types of sensors capable of detecting angles, such as torque sensors, can also be set on the blade rotating shaft of the active intake grille. The vehicle control unit communicates with the sensors to obtain the detection results of the sensors. If the sensor directly detects the angle of the blade rotating shaft, the vehicle control unit directly obtains the actual angle. If the sensor detects other types of rotation data, such as torque, the vehicle control unit calculates the actual rotation angle according to the data detected by the sensor using known arithmetic formulas. The active intake grille blades are controlled to rotate by a transmission mechanism, which can be a motor. The driving output shaft of the motor is connected to the blade rotating shaft of the active intake grille. When the transmission mechanism operates, the driving output shaft rotates, which will naturally drive the blade rotating shaft of the active intake grille to rotate. During the rotation process, the blade angle will approach the expected angle. When judging whether the actual angle is the same as the expected angle, the actual angle and the expected angle of the active intake grille blades are subtracted to complete the comparison. If the two are the same, the result obtained by subtraction is theoretically zero. After the active intake grille blades stop rotating, the control of the active intake grille is completed. As mentioned above, theoretically, the difference between the actual angle and the expected angle of the active intake grille blades is zero. However, considering the case of allowable error, it can be considered that the result of subtracting the actual angle and the expected angle of the active intake grille blades is less than the allowable error value, then it can be considered that the actual angle and the expected angle of the active intake grille blades are consistent.

[0048] In the above solution provided in this embodiment, the blade angle matching the vehicle driving speed and the cabin temperature is used as the expected angle of the active intake grille blades. By obtaining the actual angle of the active intake grille blades and judging whether the actual angle is the same as the expected angle, if the actual angle is different from the expected angle, the active intake grille blades are controlled to rotate until the actual angle is the same as the expected angle, and then the control of the active intake grille blades is stopped, ending the control of the active intake grille. Through this solution, no matter what influence the external environment has on the active intake grille blades, it can ensure that the blade angle reaches the expected angle.

[0049] In some of the described active intake grille control methods, in step S20, the obtaining of the actual angle of the active intake grille blades includes:

[0050] S201: Obtain the real-time torque of the active intake grille blades.

[0051] The real-time torque can be detected by a torque sensor on the blade shaft of the active intake grille blades.

[0052] S202: Take the starting moment when controlling the rotation of the active intake grille blades as the initial moment, and obtain the initial angle of the active intake grille blades at the initial moment.

[0053] The initial angle of the active intake grille blades can be detected by a sensor arranged on the blade rotating shaft of the active intake grille.

[0054] S203: Obtain the acting duration of the real-time torque, query the rotation angle comparison table of the active intake grille blades, and determine the blade rotation angle corresponding to the real-time torque and the acting duration; wherein, when the active intake grille blades rotate in the first direction, the blade rotation angle is positive, and when the active intake grille blades rotate in the second direction, the blade rotation angle is negative, and the first direction is opposite to the second direction.

[0055] Determine the duration when the real-time torque exerts a torsional force on the blade shaft as the acting duration of the real-time torque. The difference between the current actual moment and the initial moment can be directly used as the acting duration. The rotation angle comparison table can be pre-stored in the vehicle controller. For the active intake grille, the torque acts on the blade shaft, which can drive the blade shaft to rotate, and then drive the blades to rotate. The blade shaft itself has a certain damping force, and the damping force can also form a damping torque on the blade shaft. Taking the torque in the rotation direction as positive and the damping torque as negative, finally, the final torque that can make the blade shaft rotate can be calculated, and then the blade rotation angle can be calculated. The actual damping parameters, diameter and other parameters of the blade shaft can be determined in advance, so the corresponding relationship between the real-time torque and the rotation angle can also be determined in advance. After determination, it can be directly stored in the vehicle controller and directly retrieved when needed.

[0056] S204: Take the sum of the initial angle and the blade rotation angle as the actual angle.

[0057] Through the solution of the present application, the actual angle can be obtained by using the real-time torque on the blade shaft of the active intake grille blades, which can achieve the effect of obtaining two parameters with one sensor and simplify the structure of the entire control system.

[0058] In some of the described active intake grille control methods, the controlling the rotation of the active intake grille blades in step S20 includes:

[0059] S211: Obtain the expected current of the transmission mechanism corresponding to the expected angle.

[0060] The expected current of the transmission mechanism can correspond to the magnitude of the output power or the work done by its driving output shaft, and the driving output shaft is directly connected to the blade shaft. Therefore, there can be a one-to-one correspondence between the expected angle and the expected current, and the corresponding relationship can be stored in the vehicle controller in advance.

[0061] S212: Output a transmission control signal to the transmission mechanism, and the transmission control signal is used to control the transmission mechanism to operate at the expected current and drive the active intake grille blades to rotate.

[0062] In this solution, the transmission mechanism is controlled by changing the current of the transmission mechanism, which has a stable and reliable effect.

[0063] Preferably, step S20 in the above solution further includes:

[0064] S221: Obtain the angle difference between the actual angle and the expected angle.

[0065] During the rotation of the active intake grille blades, the actual angle changes in real time, and the difference between it and the expected angle also changes during the change process. The angle difference can be determined by directly subtracting the two.

[0066] S222: If the angle difference is less than the set threshold, reduce the expected current to the target current.

[0067] In this solution, the power for controlling the rotation of the active intake grille blades is divided into coarse adjustment and fine adjustment. If there is a large difference between the actual angle and the expected angle, the blades are rotated by a large current. If the difference between the actual angle and the expected angle is small, the blades are rotated by a small current, thereby improving the control accuracy of the blade rotation. Among them, the set threshold can be within 5% of the expected angle, preferably 3% of the expected angle.

[0068] S223: Output a target control signal to the transmission mechanism, and the target control signal is used to control the transmission mechanism to operate at the target current until the actual angle is consistent with the expected angle.

[0069] As mentioned above, through this method, the control accuracy of the rotation angle of the active intake grille blades can be improved.

[0070] In some solutions, such as Figure 2 shown, in step S20 of the active intake grille control method, it further includes:

[0071] S231: During the process of controlling the rotation of the active intake grille blades, judge whether the real-time torque of the active intake grille blades is greater than the torque upper limit threshold.

[0072] The upper torque limit threshold is determined based on the torque that can damage the active intake grille blades. That is, if the real-time torque is greater than the upper torque limit threshold, it may cause a failure of the active intake grille blades.

[0073] S232: If the real-time torque is greater than the upper torque limit threshold, output a transmission interruption signal to the transmission mechanism; the transmission interruption signal is used to control the transmission mechanism to stop operating.

[0074] This solution stops driving the intake grille blades when it may cause a failure of the active intake grille blades, thereby achieving protection for the active intake grille.

[0075] The embodiment of the present application further provides an active intake grille control device, as Figure 3 shown, including:

[0076] A data acquisition module 10, configured to acquire the desired angle of the active intake grille blades, where the desired angle is the blade angle matching the vehicle driving speed and the temperature inside the vehicle cabin; the desired angle can be acquired by using an existing solution, such as acquiring the vehicle driving speed and the temperature inside the vehicle cabin during vehicle driving, and considering the balance between vehicle wind resistance, the overall vehicle cooling performance, and air conditioning comfort, the desired angle can be determined. The balance requirements can be determined by calibration tests and other means before the vehicle leaves the factory.

[0077] The control output module 20 is configured to obtain the actual angle of the active intake grille vane. If the actual angle is different from the desired angle, it controls the active intake grille vane to rotate until the actual angle is the same as the desired angle, and then controls the active intake grille vane to stop rotating. The actual angle of the active intake grille vane can be detected by an angle sensor arranged on the vane rotating shaft of the active intake grille. Other types of sensors capable of detecting angles, such as torque sensors, can also be arranged on the vane rotating shaft of the active intake grille. The vehicle controller communicates with the sensor to obtain the detection result of the sensor. If the sensor directly detects the angle of the vane rotating shaft, the vehicle controller directly obtains the actual angle. If the sensor detects other types of rotation data, such as torque, the vehicle controller calculates the actual rotation angle according to the data detected by the sensor using a known operation formula. A transmission mechanism is used to control the rotation of the active intake grille vane. The transmission mechanism can be a motor, and the drive output shaft of the motor is connected to the vane rotating shaft of the active intake grille. When the transmission mechanism operates, the drive output shaft rotates, which will naturally drive the vane rotating shaft of the active intake grille to rotate. During the rotation process, the vane angle will approach the desired angle. When judging whether the actual angle is the same as the desired angle, the actual angle and the desired angle of the active intake grille vane are subtracted to complete the comparison. If the two are the same, the result obtained by subtraction is theoretically zero. After the active intake grille vane stops rotating, the control of the active intake grille is completed. As mentioned above, theoretically, the difference between the actual angle and the desired angle of the active intake grille vane is zero. However, considering the case of allowable error, it can be considered that the result after subtracting the actual angle and the desired angle of the active intake grille vane is less than the allowable error value, then the actual angle and the desired angle of the active intake grille vane are considered to be the same.

[0078] In the above solution provided by this embodiment, the vane angle matching the vehicle driving speed and the cabin temperature is used as the desired angle of the active intake grille vane. By obtaining the actual angle of the active intake grille vane and judging whether the actual angle is the same as the desired angle, if the actual angle is different from the desired angle, the active intake grille vane is controlled to rotate until the actual angle is the same as the desired angle, and then the control of the active intake grille is ended. Through this solution, no matter what kind of influence the external environment has on the active intake grille vane, it can ensure that the vane angle reaches the desired angle.

[0079] In some solutions, the control output module 20 is further configured to obtain the real-time torque of the active intake grille blades; take the start time when controlling the rotation of the active intake grille blades as the initial time, and obtain the initial angle of the active intake grille blades at the initial time; obtain the duration of action of the real-time torque; query the rotation angle look-up table of the active intake grille blades, and determine the blade rotation angle corresponding to the real-time torque and the duration of action; wherein, when the active intake grille blades rotate in the first direction, the blade rotation angle is a positive value, and when the active intake grille blades rotate in the second direction, the blade rotation angle is a negative value, and the first direction is opposite to the second direction; use the sum of the initial angle and the blade rotation angle as the actual angle. In this solution, the real-time torque can be detected by a torque sensor on the blade shaft of the active intake grille blades. Determine the duration of the torsional force exerted by the real-time torque on the blade shaft. The rotation angle look-up table can be pre-stored in the vehicle controller. For the active intake grille, the torque acts on the blade shaft, which can drive the blade shaft to rotate, and then drive the blades to rotate. The blade shaft itself has a certain damping force, and the damping force can also form a damping torque on the blade shaft. Taking the torque in the rotation direction as positive and the damping torque as negative, finally, the final torque that can make the blade shaft rotate can be calculated, and then the rotation angle can be calculated. The actual damping parameters, diameter and other parameters of the blade shaft can be determined in advance, so the corresponding relationship between the real-time torque and the rotation angle can also be determined in advance. After determination, it can be directly stored in the vehicle controller and directly retrieved when needed. Through the solution of the present application, the actual angle can be obtained by using the real-time torque on the blade shaft of the active intake grille blades, and the effect of obtaining two parameters with one sensor can be achieved, simplifying the structure of the entire control system.

[0080] In some solutions, the control output module 20 is further configured to obtain the expected current of the transmission mechanism corresponding to the expected angle; output a transmission control signal to the transmission mechanism, and the transmission control signal is used to control the transmission mechanism to operate with the expected current and drive the active intake grille blades to rotate. In this solution, the expected current of the transmission mechanism can correspond to the output power or work done by its driving output shaft, and the driving output shaft is directly connected to the blade shaft. Therefore, there can be a one-to-one correspondence between the expected angle and the expected current, and the corresponding relationship can be pre-stored in the vehicle controller. Controlling the transmission mechanism by changing the current of the transmission mechanism has a stable and reliable effect.

[0081] Preferably, the control output module 20 in the above solution is further configured to obtain the angle difference between the actual angle and the desired angle; if the angle difference is less than a set threshold, the desired current is reduced to a target current, and a target control signal is output to the transmission mechanism. The target control signal is used to control the transmission mechanism to operate at the target current until the actual angle is consistent with the desired angle. In this solution, during the rotation of the active intake grille blades, the actual angle changes in real time, and the difference between it and the desired angle also changes during the change process. The angle difference can be determined by directly subtracting the two. The power for controlling the rotation of the active intake grille blades is divided into coarse adjustment and fine adjustment. If there is a large difference between the actual angle and the desired angle, the blades are rotated by a large current. If the difference between the actual angle and the desired angle is small, the blades are rotated by a small current, thereby improving the accuracy of blade rotation control. Among them, the set threshold can be within 5% of the desired angle, preferably 3% of the desired angle. Through this solution, the accuracy of the rotation angle control of the active intake grille blades can be improved.

[0082] In some solutions, the device further includes a torque judgment module, configured to judge whether the real-time torque of the active intake grille blades is greater than a torque upper limit threshold during the process of controlling the rotation of the active intake grille blades. If the real-time torque is greater than the torque upper limit threshold, a transmission interruption signal is output to the transmission mechanism; the transmission interruption signal is used to control the transmission mechanism to stop operating. In this solution, the torque upper limit threshold is determined according to the torque that will damage the active intake grille blades, that is, if the real-time torque is greater than the torque upper limit threshold, it may cause a failure of the active intake grille blades. When it may cause a failure of the active intake grille blades, the driving of the intake grille blades is stopped to achieve the protection of the active intake grille.

Preferably, the rotation detection sensor 42 is a torque sensor, and the torque sensor detects the real-time torque of the active intake grille blade and sends the actual angle to the vehicle's vehicle controller. Through the active intake grille of the present application, the rotation state of the blade can be monitored in real time, and the monitoring result is sent to the vehicle controller for the vehicle controller to control the active intake grille.
