[0002] Long-term exposure to the sun with strong ultraviolet rays can easily cause skin allergies and redness, and in severe cases may cause skin cancer.

[0060] It should be noted that, in the absence of conflict, the features in the embodiments of the present application may be combined with each other.

[0061] Please also read Figure 1-2 , Figure 1 is a schematic structural diagram of a vehicle roof control system provided in an embodiment of the present application; Figure 2 The present application provides a vehicle roof control method, the control method is applied to Figure 1 The vehicle roof control system 100 shown in the figure is used to control the roof 10 on the vehicle to open or close. Figure 2 As shown, the control method comprises the following steps:

[0062] Step S1, obtaining ultraviolet intensity information outside the vehicle;

[0063] Step S2, judging whether the ultraviolet intensity outside the vehicle exceeds the standard according to the ultraviolet intensity information; and

[0064] Step S3, when it is determined that the ultraviolet intensity outside the vehicle exceeds the standard and the roof is in an open state, controlling the roof 10 to close.

[0065] The vehicle roof control method provided in the present application obtains the ultraviolet intensity information outside the vehicle, and when it is determined that the ultraviolet intensity outside the vehicle exceeds the standard and the roof 10 is in an open state according to the ultraviolet intensity information, the roof 10 is controlled to close automatically when the vehicle encounters scorching sun during driving, without the need for manual operation by the driver, which has a higher level of intelligence and driving safety, and a better driving experience.

[0066] In some embodiments, Figure 1 As shown, the vehicle includes an ultraviolet sensor 20, and the ultraviolet intensity information includes an ultraviolet intensity value. The step of obtaining the ultraviolet intensity information outside the vehicle includes:

[0067] The ultraviolet intensity value outside the vehicle is acquired by the ultraviolet sensor 20 .

[0068] Further, judging whether the ultraviolet intensity outside the vehicle exceeds a standard according to the ultraviolet intensity information includes:

[0069] According to the magnitude relationship between the ultraviolet intensity value outside the vehicle and a preset intensity threshold, it is determined whether the ultraviolet intensity outside the vehicle exceeds the standard.

[0070] The UV intensity value refers to the amount of UV radiation in the sun that is emitted on the ground, and is usually used to measure the possible impact of UV on the human body. The unit of measurement for the UV intensity value is microwatts per square centimeter (μW / cm 2 ), which is used to reflect the power density of ultraviolet radiation.

[0071] When the ultraviolet intensity in the air exceeds 5μW / cm 2 When the ultraviolet light intensity reaches a medium level, it indicates that the ultraviolet light intensity has reached a medium level, which has a medium level of harmful effect on human skin. Therefore, in some embodiments, the preset intensity threshold is 5 μW / cm 2 In this way, when the ultraviolet intensity has reached a medium intensity, it is determined that the ultraviolet intensity outside the vehicle exceeds the standard, and the canopy 10 is controlled to be closed, which can better protect the skin of the driver and passengers from the harm of ultraviolet rays.

[0072] In some embodiments, there are multiple ultraviolet sensors 20. The step of judging whether the ultraviolet intensity outside the vehicle exceeds the standard according to the magnitude relationship between the ultraviolet intensity value outside the vehicle and a preset intensity threshold comprises:

[0073] Whether the ultraviolet intensity outside the vehicle exceeds the standard is determined based on the relationship between the average intensity of the ultraviolet intensity values ​​acquired by the plurality of ultraviolet sensors 20 and a preset intensity threshold.

[0074] In some embodiments, a plurality of the UV sensors 20 may be mounted on the top of the roof 10 of the vehicle.

[0075] In other embodiments, the vehicle may also be provided with only one ultraviolet sensor 20. It is not difficult to understand that, compared with judging whether the ultraviolet intensity outside the vehicle exceeds the standard based on the magnitude relationship between the ultraviolet intensity value obtained by a single ultraviolet sensor 20 and a preset intensity threshold, judging the quality of the air in the environment where the vehicle is located based on the intensity average of the ultraviolet intensity values ​​obtained by multiple ultraviolet sensors 20 can avoid erroneous judgment results due to detection errors or failures of a single ultraviolet sensor 20, and the system has higher accuracy.

[0076] Further, judging whether the ultraviolet intensity outside the vehicle exceeds the standard according to the relationship between the average intensity of the ultraviolet intensity values ​​acquired by the plurality of ultraviolet sensors 20 and a preset intensity threshold value includes:

[0077] Calculate the average intensity of the ultraviolet intensity values ​​obtained by the plurality of ultraviolet sensors 20 at a preset interval;

[0078] Determine whether the intensity average value calculated each time is greater than the preset intensity threshold;

[0079] When it is determined that the intensity average value calculated for the current time is greater than the preset intensity threshold, determining whether the duration for which the intensity average value remains greater than the preset intensity threshold is greater than a first preset duration; and

[0080] When it is determined that the duration for which the intensity average value remains greater than the preset intensity threshold is greater than the first preset duration, it is determined that the ultraviolet intensity outside the vehicle exceeds the standard.

[0081] In this embodiment, when it is determined that the duration for which the average intensity value remains greater than the preset intensity threshold value is greater than the first preset duration, it is determined that the ultraviolet intensity outside the vehicle exceeds the standard, and the canopy 10 is controlled to be closed, which can improve the accuracy of the detection of hot sun weather. The first preset duration can be set by the user as needed, for example, 60s.

[0082] Furthermore, when it is determined that the intensity average value calculated for the current time is greater than the preset intensity threshold, determining whether a duration for which the intensity average value remains greater than the preset intensity threshold is greater than a first preset duration includes:

[0083] When it is determined that the intensity average value calculated currently is greater than the preset intensity threshold, the duration for which the intensity average value remains greater than the preset intensity threshold is obtained according to the continuous cumulative number of times that the intensity average value is greater than the preset intensity threshold and the preset interval time; and

[0084] It is determined whether the duration for which the intensity average value remains greater than the preset intensity threshold is greater than a first preset duration.

[0085] Among them, the continuous cumulative number of times that the intensity average value is greater than the preset intensity threshold value refers to the cumulative number of times that the intensity average values ​​calculated for multiple consecutive times are greater than the preset intensity threshold value, that is, each time the calculated intensity average value is less than the preset intensity threshold value, the cumulative number is reset to zero. Exemplarily, the preset interval time is 1s. If the intensity average value calculated for the 100th time is less than the preset intensity threshold value, the intensity average values ​​calculated for the 101st to 200th times are all greater than the preset intensity threshold value, and the intensity average value calculated for the 201st time is less than the preset intensity threshold value, then the continuous cumulative number of times that the intensity average value is greater than the preset intensity threshold value is 100 times, that is, the duration for which the intensity average value remains greater than the preset intensity threshold value is 100s.

[0086] In some embodiments, Figure 1 As shown, the vehicle further includes a central control unit 70. The ultraviolet intensity information includes an ultraviolet index. The step of obtaining the ultraviolet intensity information outside the vehicle includes:

[0087] The central control unit 70 is used to obtain the current ultraviolet index of the area where the vehicle is located.

[0088] The central control unit 70 may include a central control PAD, a weather APP may be installed on the central control PAD, and the current ultraviolet index of the area where the vehicle is located may be obtained through the weather APP in the central control PAD.

[0089] In some embodiments, judging whether the ultraviolet intensity outside the vehicle exceeds a standard according to the ultraviolet intensity information includes:

[0090] When the ultraviolet index is higher than or equal to a preset index threshold, it is determined that the ultraviolet intensity outside the vehicle exceeds the standard.

[0091] The UV index is a dimensionless physical quantity used to describe the UV intensity level generated by solar radiation on the ground. The range of the UV index is usually expressed by numbers from 0 to 15. When the UV index value is 0 to 2, it means that the UV intensity is the weakest and has basically no effect on the human body; when the UV index value is 3 to 4, it means that the UV intensity is relatively weak and the possible effect on the human body is relatively small; when the UV index value is 5 to 6, it means that the amount of UV is of medium intensity and has a medium-intensity harmful effect on human skin; when the UV index value is 7 to 9, it means that there is a strong UV irradiation intensity, and the possible effect on the human body is relatively large, and corresponding protective measures need to be taken; when the UV index value is 10 or above, it means that the UV irradiation is very strong and has the greatest effect on the human body, and protective measures must be taken. Exemplarily, the preset index threshold is 5.

[0092] In this way, the closing of the canopy 10 is controlled according to the UV index obtained by the weather APP in the central control PAD, which has a higher level of intelligence, can further protect the skin of the driver and passengers from the harm of ultraviolet rays, and further improve the driving experience of the driver and passengers.

[0093] In some embodiments, the vehicle further includes a canopy position sensor 50. When it is determined that the ultraviolet intensity outside the vehicle exceeds a standard and the canopy 10 is in an open state, controlling the canopy 10 to close includes:

[0094] When it is determined that the ultraviolet intensity outside the vehicle exceeds the standard, the canopy position sensor 50 is controlled to start and detect the opening and closing state of the canopy 10; and,

[0095] When it is detected that the roof 10 is in the open state, the roof 10 is controlled to be closed.

[0096] Thus, by default, the roof position sensor 50 is in a dormant state or a shutdown state, and only when it is determined that the ultraviolet intensity outside the vehicle exceeds the standard, the roof position sensor 50 is controlled to start, thereby saving system resources and power.

[0097] In some embodiments, after controlling the canopy position sensor 50 to start and detect the open / closed state of the canopy 10 when it is determined that the ultraviolet intensity outside the vehicle exceeds the standard, the control method further includes:

[0098] When it is detected that the canopy 10 is in the closed state, the canopy 10 is controlled to continue to remain in the closed state.

[0099] In some embodiments, when it is determined that the ultraviolet intensity outside the vehicle exceeds a standard and the roof 10 is in an open state, controlling the roof 10 to close includes:

[0100] When the ultraviolet intensity outside the vehicle exceeds the standard and the canopy 10 is in an open state, obtaining the current speed of the vehicle and determining whether the current speed is lower than a preset speed threshold; and,

[0101] When it is determined that the current vehicle speed is lower than the preset speed threshold, the roof 10 is controlled to be closed.

[0102] For example, Figure 1 As shown, the vehicle further includes an intelligent integrated power brake (IPB) system, and the intelligent integrated power brake system includes a vehicle speed sensor 90 , through which the current vehicle speed of the vehicle can be acquired.

[0103] According to research, when the vehicle is driving too fast, forcibly closing the roof may cause some problems and risks, such as: 1. Increased air resistance: After closing the roof, the aerodynamic characteristics of the vehicle will change, which may lead to increased air resistance. This will affect the acceleration performance, fuel efficiency and stability of the vehicle; 2. Increased noise inside the car: After closing the roof, the sound insulation effect between the interior and the external environment will be reduced, and the noise inside the car may increase, affecting the comfort of the driver and passengers. 3. Changes in temperature inside the car: After closing the roof, the temperature inside the car may be affected. When driving at high speed, the airflow outside the car may increase the temperature inside the car, especially in hot weather; 4. Safety hazards: When driving at high speed, if the roof is not closed firmly, it may suddenly open during driving, which may cause safety hazards. In addition, if the vehicle encounters an emergency and requires emergency braking when driving at high speed, the sudden closing of the roof may cause a certain degree of injury to the driver and passengers; 5. Difficulty in vehicle control: When driving at high speed, closing the roof may affect the handling of the vehicle. Especially in the case of crosswind or unstable airflow, the vehicle may shake, and the driver needs to drive more carefully. Therefore, in this embodiment, the canopy 10 is controlled to close only when it is determined that the current vehicle speed is lower than the preset speed threshold, which can improve driving safety and enhance the driving experience of the driver and passengers. The preset speed threshold can be obtained through experiments, for example, 50 km / h.

[0104] Furthermore, if Figure 1 As shown, the vehicle further includes a prompt unit 80. After obtaining the current vehicle speed of the vehicle and determining whether the current vehicle speed is lower than a preset speed threshold, the control method further includes:

[0105] When it is determined that the current vehicle speed is higher than the preset speed threshold, controlling the prompt unit 80 to send a corresponding prompt signal to remind the driver to slow down; and

[0106] When the vehicle decelerates to a speed lower than a preset speed threshold, the roof 10 is controlled to close.

[0107] In this way, the driver can be reminded to reduce the speed as soon as possible, so as to control the roof 10 to be closed as soon as possible, which can reduce the time that the driver and passengers are exposed to polluted air and improve the driving experience of the driver and passengers.

[0108] In some embodiments, the prompt unit 80 includes a roof closing action indicator light (not shown) and / or a voice module (not shown). The controlling the prompt unit 80 to send a corresponding prompt signal includes:

[0109] Controlling the roof closing action indicator light to flash; and / or,

[0110] The voice module is controlled to broadcast a first voice message for reminding the driver to slow down.

[0111] In some embodiments, the vehicle further includes a central control unit 70. The control method further includes:

[0112] According to the ultraviolet intensity values ​​acquired by the plurality of ultraviolet sensors 20, judging whether each of the ultraviolet sensors 20 is normal; and,

[0113] When there is at least one faulty sensor among the plurality of ultraviolet sensors 20 , the ultraviolet intensity value acquired by the faulty sensor is discarded, and the central control unit 70 is controlled to send a second prompt signal to remind the driver to replace the faulty sensor in time.

[0114] Discarding the ultraviolet intensity value obtained by the faulty sensor means that when calculating the intensity average value of the ultraviolet intensity values ​​obtained by the plurality of ultraviolet sensors, the ultraviolet intensity value obtained by the faulty sensor does not participate in the calculation.

[0115] In this way, when some of the plurality of ultraviolet sensors 20 fail, the canopy 10 can still be controlled to be opened or closed by relying on the ultraviolet intensity values ​​obtained by other normal ultraviolet sensors, thereby improving the reliability of the system.

[0116] Further, judging whether each of the ultraviolet sensors 20 is normal according to the ultraviolet intensity values ​​acquired by the multiple ultraviolet sensors 20 includes:

[0117] When the duration of the unresponsiveness of the ultraviolet sensor 20 is greater than the second preset duration, or the difference between the ultraviolet intensity value obtained by the ultraviolet sensor 20 and the intensity average value of the ultraviolet intensity values ​​obtained by other ultraviolet sensors 20 is greater than a preset error threshold, the ultraviolet sensor 20 is determined to be a faulty sensor.

[0118] It is not difficult to understand that when one of the ultraviolet sensors 20 does not respond for a long time or the difference between the ultraviolet intensity value obtained and the ultraviolet intensity value obtained by other ultraviolet sensors 20 is too large, it can be preliminarily determined that the ultraviolet sensor 20 is faulty.

[0119] In some embodiments, the control method further includes:

[0120] When a first voice control instruction for triggering the opening of the roof 10 is received, controlling the opening of the roof 10; and / or,

[0121] When a second voice control command for triggering the closing of the roof 10 is received, the roof 10 is controlled to be closed.

[0122] The vehicle roof control system 100 has a voice control function, and the driver and passenger can output a voice wake-up command to the central control unit 70 to wake up the voice control function of the vehicle roof control system 100 and execute the relevant voice control command. For example, the second voice control command may include keywords such as "close the roof", "too sunny", "ultraviolet rays are too strong", etc. In this way, the driver and passenger can control the opening and / or closing of the roof 10 without manual operation, which is more intelligent.

[0123] In some embodiments, Figure 1 As shown, the vehicle further includes a motor 40 and a motor speed sensor 60, wherein the motor 40 is connected to the roof 10, and the motor 40 drives the roof 10 to close when rotating in a first direction, and drives the roof 10 to open when rotating in a second direction, wherein the second direction is opposite to the first direction. The motor speed sensor 60 is connected to the motor 40, and is used to detect the speed of the motor 40. Exemplarily, the motor speed sensor 60 includes a Hall sensor.

[0124] The controlling the roof 10 to close includes:

[0125] The motor 40 is controlled to rotate in a first direction to drive the roof 10 to close.

[0126] The control method further comprises:

[0127] In the process of controlling the motor 40 to rotate in the first direction, obtaining the rotation speed of the motor 40;

[0128] Determining whether the canopy 10 encounters an obstacle during the closing process according to the rotation speed of the motor 40; and

[0129] When it is determined that the roof 10 encounters an obstacle during the closing process, the motor 40 is controlled to stop rotating or rotate by a preset angle in a second direction.

[0130] The preset angle can be set as required and is not limited here.

[0131] In this way, it is possible to prevent body parts of the driver and passengers or other objects from being caught by the roof 10 , thereby providing higher safety.

[0132] It should be noted that when the canopy 10 encounters an obstacle during the closing process, the rotation speed of the motor 40 will quickly drop from the normal rotation speed to 0, that is, the absolute value of the acceleration of the motor 40 will suddenly become very large. Therefore, in some embodiments, judging whether the canopy 10 encounters an obstacle during the closing process based on the rotation speed of the motor 40 includes:

[0133] When the absolute value of the acceleration of the rotation speed of the motor 40 is greater than a preset acceleration threshold, it is determined that the roof 10 encounters an obstacle during the closing process.

[0134] Furthermore, the control method further includes:

[0135] When it is determined that the roof 10 encounters an obstacle during the closing process, the prompt unit 80 is controlled to send a corresponding prompt signal to remind the driver and passenger to confirm the state of the roof 10 and detect the obstacle.

[0136] Exemplarily, the prompt unit 80 includes a canopy anti-pinch warning indicator light (not shown) and / or a voice module. The control of the prompt unit 80 to send a corresponding prompt signal includes:

[0137] Control the roof anti-pinch warning indicator light to flash; and / or,

[0138] The voice module is controlled to broadcast the second voice information.

[0139] In some embodiments, after controlling the roof 10 to be closed, the control method further includes:

[0140] Control all windows of the vehicle to close.

[0141] In this way, by closing the car windows, the intensity of ultraviolet rays can be further weakened, which can better protect the skin of drivers and passengers from the harm of ultraviolet rays.

[0142] Please refer again Figure 1 Based on the same inventive concept, the present application also provides a vehicle roof control system 100 , which includes a roof 10 and a domain controller 30 .

[0143] The domain controller 30 is used to control the execution of the steps in the vehicle roof control method described in any of the above embodiments.

[0144] The domain controller 30 may be a body domain module (BDM) on the vehicle, and the domain controller 30 interacts with the vehicle via a CAN (Controller Area Network) line, such as Figure 1 As shown, the domain controller 30 is electrically connected to the ultraviolet sensor 20, the motor 40, the canopy position sensor 50, the motor speed sensor 60, the central control unit 70, the prompt unit 80 and the vehicle speed sensor 90 in the above embodiment.
