[0041] First Embodiment

[0042] The present embodiment provides a liftable sunroof control system, which can realize intelligent control of the vehicle sunroof, improve the comfort of passengers in the vehicle, reduce the user's manual operation, and bring a convenient use experience to the user.

[0043] like Figure 1 As shown, the system provided in this embodiment includes a sunroof module 1, an information acquisition module 2, and a control module 3. Among them, as far as the specific design of the sunroof module 1 is concerned, it also includes a sunroof body 11 and a sunroof lifting mechanism 12. The sunroof body 11 includes a fixed end and a lifting end, and the fixed end is rotatably connected to the roof. The sunroof lifting mechanism 12 can control the lifting end of the sunroof body to lift. The length direction of the sunroof body 11 allows the user in the car to easily see the sky, and the width direction can simultaneously meet the needs of two adults sitting side by side, and their heads can move freely outward. After the sunroof is lifted and opened, it can expand the riding and leisure space in the car, increase the air circulation with the outdoors, and can be further optimized to add a rainproof mechanism to prevent rain from entering the car. When a large number of items need to be carried, the sunroof body 11 is lifted upward, and the space formed by the lifting area can be used as a storage space in the car for traveling, and items can be placed from the inside of the vehicle, and the vehicle can also be driven in the lifted state. In particular, the lifting opening direction of the sunroof body 11 can be toward the front of the vehicle or toward the rear of the vehicle, which is not limited in this embodiment.

[0044] Furthermore, the sunroof module 1 may also be provided with a sunroof curtain, which can be opened or closed. When in the open state, it can block the sunlight and bring a more comfortable in-vehicle environment.

[0045] As for the specific design of the information acquisition module 2, it includes an instruction acquisition unit 21, an image collection unit 22, a sound collection unit 23, and a state acquisition unit 24. These units are all used to acquire information. Among them:

[0046] The instruction acquisition unit 21 is used to collect user instructions, and includes physical buttons, a touch screen, and a microphone. The physical buttons and the touch screen are used to identify the user's physical interaction actions, and the microphone is used to identify the user's voice interaction information. Such a design can obtain user instructions through multiple channels, which is convenient for users to operate.

[0047] The image collection unit 22 is used to obtain in-car image information and out-car image information, which can be completed through a camera. Among them, the in-car image information includes in-car personnel information and in-car environment information, that is, the in-car camera collects in-car environment information such as whether the car is in bed car mode, whether the seats are folded down, whether there is a mattress, and whether there are people lying in the car, the number of people, whether there are people in the back row of the car, and the size of the human body. The out-car camera can collect the sky state, etc. to assist the control module 3 in identifying weather information.

[0048] The sound collecting unit 23 is used to obtain the sound information inside the vehicle, such as the conversation sounds of the users inside the vehicle, and the sound information outside the vehicle, such as the sound of rain, wind, etc.

[0049] The state acquisition unit 24 is used to acquire the sunroof state information and vehicle operation information. Specifically, the vehicle operation information includes vehicle speed information, which can be acquired through a vehicle body sensor or a wheel speed sensor.

[0050] As for the specific design of the control module 3, it is used to send a sunroof control signal to the sunroof lifting mechanism 12 according to the information obtained by the information acquisition module 2 in accordance with preset control rules. The sunroof lifting mechanism 12 lifts the sunroof body 11 according to the sunroof control signal to achieve the purpose of adjusting the sunroof.

[0051] Specifically, the aforementioned preset control rules are:

[0052] First, according to the user's instructions, determine whether to enter normal mode or smart mode:

[0053] If it enters the normal mode, the sunroof control signal is sent directly according to the user's instructions;

[0054] If the intelligent mode is entered, a sunroof control signal is generated and sent according to the information obtained by the instruction acquisition unit 21 , the image collection unit 22 , the sound collection unit 23 , and the state acquisition unit 24 .

[0055] Furthermore, whether in normal mode or intelligent mode, if an obstacle is identified in the sunroof closing area, it is determined whether the user has made an erroneous operation: if so, the sunroof state is kept unchanged; if not, the sunroof control signal is sent normally. The above method for determining whether there is an erroneous operation may be: when an obstacle is identified in the sunroof closing area, such as the head of the person in the car exceeds the area where the lifting sunroof is closed, an alarm prompt is synchronously activated. If the user does not issue an instruction again at this time, that is, the person in the car has the subjective intention to keep the sunroof open, it is determined to be an erroneous operation, and the lifting sunroof will not be closed; but if the user sends an instruction again, it is determined that there is no erroneous operation and the instruction continues to be executed. Such an operation can avoid affecting the opening and closing state of the sunroof due to the user's erroneous operation, and improve the intelligence and accuracy of the sunroof control.

[0056] Furthermore, the sunroof control signal sent by the control module 3 may include a sunroof opening signal, a sunroof closing signal, a sunroof locking signal, and a sunroof opening angle adjustment signal.

[0057] The specific operation process of the system provided in this embodiment is described as follows: Figure 2 shown.

[0058] In step S1 , the user sends a user command to raise the sunroof through a physical button, a touch screen of the MP5, or a voice command.

[0059] Step S2: The lifting sunroof control module identifies the mode selected by the user. If it is in normal mode, it goes to step S3, and if it is in smart mode, it goes to step S5.

[0060] Step S3: Identify and enter the normal mode.

[0061] Step S4: The lifting sunroof is only manually controlled to lift or lower, open or close, etc.

[0062] Step S5: When entering the smart mode, the opening of the sunroof is associated with the external environment, specifically:

[0063] Step S6: When entering the lifting sunroof intelligent control mode, obtaining user instructions, in-vehicle image information, out-vehicle image information, in-vehicle sound information, out-vehicle sound information, sunroof status information, and vehicle operation information, specifically:

[0064] Step S61: judging the opening state of the lift sunroof, i.e., sunroof state information, according to the opening signal of the lift sunroof and the state signal of the locking switch;

[0065] Step S62, the current speed of the vehicle can be determined according to the vehicle speed signal. Specifically, the vehicle speed signal, i.e., the vehicle operation information, can be obtained through the body sensor or the wheel speed sensor; the situation inside the vehicle can be analyzed according to the in-vehicle image signal collected by the in-vehicle camera, such as whether the vehicle is in bed car mode, whether the seats are folded down, whether there is a mattress, whether there are people lying in the vehicle, the number of people, whether there are people in the back row of the vehicle, the body size, i.e., the in-vehicle image information and the outside vehicle image information; the rain sensor and the sound sensor identify whether it is raining, and combine the outside vehicle image signal to identify more weather information, etc., and combine the above information to judge the vehicle speed, the outside vehicle environment, the inside vehicle environment, etc. to judge whether further intelligent control is needed, and to judge whether to continue to execute the opening or maintain the closing, such as whether it is raining or whether it is windy.

[0066] Step S63: If it is determined that further intelligent control is needed, the intelligent control range of the sunroof needs to be further determined based on the information obtained above, such as maintaining closing, maintaining lifting, partially closing, partially lifting, etc.

[0067] S7: Continue intelligent operation according to the information obtained by the information acquisition module 2. For example, when it rains suddenly, the closing of the lifting sunroof is linked to the weather environment. If the vehicle speed is not 0 and the intelligent control is being performed, the lifting height of the lifting sunroof can be linked to the vehicle speed; after the sunroof is lifted, the vehicle is driving, and the design has considered the influence of wind resistance and wind noise in advance. A certain vehicle speed corresponds to a certain and allowable lifting height. After the vehicle is lifted, the space inside the car is significantly larger than the normal closed state, and the thermal insulation performance inside the car is appropriately reduced. At this time, the temperature and wind speed of the air conditioner and the lifting height of the lifting sunroof and the space formed are associated to provide comfortable air conditioning to the greatest extent. If the head of the person in the car exceeds the area where the lifting sunroof is closed, the alarm prompt is activated synchronously; when it is judged that the person in the car has the subjective intention to keep the sunroof open, it is considered to be a wrong operation, and the lifting sunroof will not be closed. If the user sends the instruction again, it is considered that the customer has the subjective intention, and it is executed.

[0068] Second Embodiment

[0069] This embodiment provides a method for controlling a liftable sunroof, comprising the following steps:

[0070] First, obtain user instructions, in-car image information, out-car image information, in-car sound information, out-car sound information, sunroof status information, and vehicle operation information. The user instructions can be obtained by identifying the user's physical interaction actions and sound interaction information. At the same time, the in-car image information includes in-car occupant information and in-car environment information; the vehicle operation information includes vehicle speed information.

[0071] Then, according to the preset control rules, a sunroof control signal is sent according to the information acquired by the information acquisition module to lift the sunroof body, wherein the preset control rules are:

[0072] According to the user instruction, determine whether to enter the normal mode or the smart mode:

[0073] If it enters the normal mode, the sunroof control signal is sent directly according to the user's instructions;

[0074] If the intelligent mode is entered, the sunroof control signal is sent according to the information obtained by the instruction acquisition unit, the image collection unit, the sound collection unit, and the status acquisition unit.

[0075] Furthermore, the preset control rules also include: after entering the normal mode or the intelligent mode, if an obstacle is identified in the sunroof closing area, it is determined whether the user has made an erroneous operation: if so, the sunroof state is kept unchanged; if not, the sunroof control signal is sent normally. The method for determining whether it is an erroneous operation may be: when an obstacle is identified in the sunroof closing area, for example, the head of the person in the car exceeds the area where the lifting sunroof is closed, an alarm prompt is synchronously started. If the user does not issue an instruction again at this time, that is, the person in the car has the subjective intention to keep the sunroof open, it is determined to be an erroneous operation, and the lifting sunroof is not closed; but if the user sends an instruction again, it is determined that there is no erroneous operation and the execution continues. Such an operation can avoid affecting the opening and closing state of the sunroof due to the user's erroneous operation, and improve the intelligence and accuracy of the sunroof control.

[0076] Furthermore, the sunroof control signal includes a sunroof opening signal, a sunroof closing signal, a sunroof locking signal, and a sunroof opening angle adjustment signal, so as to realize diverse control of the sunroof and meet the user's purpose.
