[0033] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0035] According to an embodiment of the present invention, an embodiment of a method for controlling an active suspension in a vehicle is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0036] Figure 1 is a flow chart of a control method of an active suspension in a vehicle according to an embodiment of the present invention. Figure 1As shown, the method may include the following steps:

[0037] Step S102, obtaining size information of the target object.

[0038] In the technical solution provided in step S102 of the present invention, the target object may be an accessory item that needs to be deployed on the roof of the vehicle, such as a suitcase, a bicycle rack, a scooter, etc. The vehicle may be a new energy vehicle or a fuel vehicle. The size information may be used to indicate the size and shape of the target object, such as the length, width, and height of the target object.

[0039] In this embodiment, by determining the size information of the item, it is possible to determine whether the item can be deployed on the roof, ensuring that the item is deployed safely and securely on the roof, preventing the item from falling and causing danger to the vehicle itself or other road users, and also making rational use of the roof space to improve the vehicle's loading capacity.

[0040] Optionally, the size information may be obtained by measuring the length, width and height of the target object using a laser rangefinder or a distance measuring instrument. Alternatively, a measuring tool such as a tape measure or a ruler may be used to directly measure the size of the target object. Alternatively, a camera or a camera may be used to take a picture of the target object and the size of the target object may be measured using image processing software on a computer.

[0041] It should be noted that the above-mentioned method and process for obtaining the size information of the target object are only examples and are not specifically limited here. As long as the process and method can be used to obtain the size information of the target object to measure whether the target object can be deployed on the roof, it is within the protection scope of the embodiments of the present invention.

[0042] Step S104 , when the size information meets the size information threshold and the target object has been deployed on the roof, in response to the vehicle being in a driving state, detecting the road on which the vehicle is driving.

[0043] In the technical solution provided in the above step S104 of the present invention, after obtaining the size information of the target object, it can be determined whether the size information meets the size information threshold. When the size information meets the size information threshold and the target object has been deployed on the roof, when the vehicle is in a driving state, the road on which the vehicle is traveling can be detected. The size information threshold is a critical threshold of the size information used to determine whether the vehicle has the requirements for roof loading.

[0044] In this embodiment, the size information of the target object carried by the vehicle on the roof can be determined. By setting the size information threshold, when the size information meets the size information threshold and the target object has been deployed on the roof, it can be determined whether the vehicle is in a driving state. If the vehicle is in a driving state, the road on which the vehicle is traveling can be detected. The vehicle-mounted system can monitor and analyze the road conditions around the vehicle to detect potential problems or dangers in advance and ensure driving safety. When the size information does not meet the size information threshold, it can be prompted that the target object does not meet the requirements for deployment on the roof.

[0045] Optionally, the road on which the vehicle is traveling may be detected using detection equipment such as on-board cameras, sensors, and a global positioning system (GPS) navigation system, and road information such as road conditions, traffic signs, traffic signals, and pedestrians may be detected.

[0046] It should be noted that the above road detection method is only an example and is not specifically limited here. As long as it can be used to detect the road on which the vehicle is traveling, it is within the protection scope of the embodiment of the present invention.

[0047] Optionally, if the size information of the target object does not meet the size information threshold, a text message may be prompted in the form of a pop-up window on the human-machine interface (HMI) system corresponding to the vehicle, or an alarm sound or voice prompt may be issued to prompt the owner that the size of the target object does not meet the requirements of roof deployment. It should be noted that the above prompt method is only an example and is not specifically limited here. As long as it can be used to prompt that the size of the target object does not meet the requirements of roof deployment, it is within the protection scope of the embodiments of the present invention.

[0048] Step S106 , in response to detecting that the road is a target road, determining a target height of an active suspension in the vehicle based at least on the size information and a height threshold of the target road.

[0049] In the technical solution provided in the above step S106 of the present invention, when the vehicle is in a driving state, after detecting the road on which the vehicle is traveling, when the road is detected as a target road, the target height of the active suspension in the vehicle can be determined based on at least the size information and the height threshold of the target road. The target road can be a road with limited height, such as a tunnel, a bridge, or a road in a specific area. Active suspension is a vehicle suspension system that can automatically adjust the hardness and height of the suspension according to different driving conditions and road conditions to provide better suspension performance and driving comfort.

[0050] Optionally, the height threshold can be used to determine whether the vehicle can pass through a road with a limited height. The height threshold can be set according to the characteristics of the target road and the requirements of the vehicle, and can be the maximum height of the vehicle passing through the target road. For example, it can be the height limit of the road height limit frame or the height limit value on the road height warning sign.

[0051] It should be noted that the above-mentioned setting method of the height threshold is only for illustration and is not specifically limited here. As long as the height of the target road can be limited to the height of the road with a limited height, it is within the protection scope of the embodiment of the present invention.

[0052] Optionally, the active suspension system can lower the vehicle body height to improve handling and stability. It can adjust the height of the vehicle suspension according to the vehicle operating status and the driver's needs to provide better driving comfort and safety.

[0053] In this embodiment, when it is detected that the road is a road with limited height, the target height of the active suspension in the vehicle can be determined by comparing the size of the object and the height of the target road with the height threshold of the target road, thereby ensuring the safe passage of the vehicle on the road with limited height, avoiding safety problems such as collisions, and improving the safety, comfort and adaptability of the vehicle when driving on roads with limited height.

[0054] Step S108: controlling the active suspension according to the control strategy corresponding to the target height.

[0055] In the technical solution provided in the above step S108 of the present invention, after determining the target height of the active suspension in the vehicle based on the size information and the height threshold of the target road, the active suspension can be controlled according to the control strategy corresponding to the target height, wherein the controlled active suspension is used to enable the vehicle with items deployed on the roof to pass the target road safely without scratches, etc. The control strategy can be to adjust the suspension height according to the target height, so that the vehicle with items deployed on the roof can adapt to different road height thresholds and pass the target road.

[0056] In this embodiment, the active suspension system of the vehicle can be adjusted and controlled through the control strategy according to the determined target height to achieve the set target height, ensuring that the vehicle avoids dangers caused by collisions when passing through a road with limited height, thereby improving the safety, comfort and adaptability of the vehicle when driving on a road with limited height. The technical effect of effectively controlling the active suspension in the vehicle is achieved, solving the technical problem of being unable to effectively control the active suspension in the vehicle.

[0057] In step S102 to step S108 of the embodiment of the present invention, considering that the space inside the vehicle is insufficient, the items can be placed on the roof. However, if placed on the roof, the vehicle may encounter some target roads during driving, which may easily cause dangers such as collisions and scratches. Therefore, the size information of the target object to be deployed on the roof of the vehicle can be obtained to determine whether the size information meets the size information threshold. When the size information meets the size information threshold, and when the target object has been deployed on the roof, the road on which the vehicle is traveling can be detected based on the vehicle being in a driving state. After detecting the road on which the vehicle is traveling, the target height of the active suspension in the vehicle can be determined based on the size information and the height threshold of the target road, and then the active suspension can be controlled to achieve the technical effect of effectively controlling the active suspension in the vehicle, thereby solving the technical problem of being unable to effectively control the active suspension in the vehicle.

[0058] The technical solution of the embodiment of the present invention is illustrated below in conjunction with preferred implementation modes.

[0059] As an optional embodiment, step S102, obtaining the size information of the target object, includes: if the terminal device of the driving object of the vehicle establishes a connection with the vehicle, inputting the size information of the target object on the terminal device; and / or, deploying the target object in front of the scanning device of the vehicle, scanning the target object using the scanning device, and determining the size information.

[0060] In this embodiment, if the terminal device of the driving object of the vehicle establishes a connection with the vehicle, the size information of the target object can be input on the terminal device, or the target object can be deployed in front of the scanning device of the vehicle, and the scanning device can be used to scan the target object and determine the size information.

[0061] Optionally, the size information of the object to be deployed on the roof can be input through a terminal device, such as a mobile phone, and the size information can include the length, width and height of the object. Alternatively, the object can be placed in front of the vehicle and the size information of the object can be automatically obtained through a scanning device equipped in the vehicle, such as a camera, millimeter wave radar, laser radar, etc.

[0062] It should be noted that the above-mentioned method for obtaining the size information of an object is only an example and is not specifically limited here. As long as it can be used for obtaining the size information of an object, it is within the protection scope of the embodiments of the present invention.

[0063] As an optional embodiment, the target object is deployed in front of a scanning device of a vehicle, the target object is scanned using the scanning device, and size information is determined, including: in response to the target object being deployed in front of the scanning device, the target object is scanned using the scanning device to obtain a scanning point cloud result of the target object; the scanning point cloud result is converted into image information of the target object; and size information is determined from the image information.

[0064] In this embodiment, when the target object is deployed in front of the scanning device of the vehicle, the scanning device can be used to scan the target object and determine the size information. When the target object is deployed in front of the scanning device, the scanning device can be used to scan the target object. The scanning point cloud result of the target object can be obtained and converted into image information of the target object, and the size information can be determined from the image information.

[0065] Optionally, the object to be measured is placed in front of the scanning device of the vehicle to ensure that the object is within the effective scanning range of the scanning device. By scanning the target object with a scanning device, such as a laser radar, a 3D camera, etc., the three-dimensional point cloud data of the target object can be obtained to obtain a point cloud result. The point cloud data can be composed of countless point coordinates, which can describe the shape and size of the target object in detail.

[0066] Optionally, the acquired point cloud data can be converted into two-dimensional image information through projection or rendering of the point cloud data for further image processing and dimension measurement.

[0067] Optionally, the size of the target object can be determined from the converted image information using image processing algorithms, such as edge detection, feature extraction, etc. The length, width and height of the target object can also be calculated by identifying the outline of the target object.

[0068] It should be noted that the above point cloud results and the method of obtaining size information are only examples and are not specifically limited here.

[0069] In this embodiment, when the user is ready to load items, he can put the items in front of the vehicle and use the on-board scanning device to scan the appearance of the items. In this way, before loading the items, you can intuitively understand whether the size of the items meets the requirements and safety standards, thereby avoiding possible damage to the items or violations, and improving driving experience and safety.

[0070] As an optional embodiment, when the size information meets the size information threshold and the target object has been deployed on the roof, in response to the vehicle being in a driving state, before detecting the road on which the vehicle is driving, the method also includes: if the size information meets the size information threshold, sending a first prompt message to the terminal device, wherein the first prompt message is used to prompt that the target object meets the requirement of being deployed on the roof, and prompts the driving object to deploy the target object on the roof; if the size information does not meet the size information threshold, sending a second prompt message to the terminal device, wherein the second prompt message is used to prompt that the target object does not meet the requirement of being deployed on the roof.

[0071] In this embodiment, after obtaining the size information of the target object, it can be determined whether the size information meets a preset size information threshold. When the size information meets the size information threshold, a first prompt message can be sent to the terminal device, prompting that the target object meets the requirement of being deployed on the roof. When the size information does not meet the size information threshold, a second prompt message can be sent to the terminal device, prompting that the target object does not meet the requirement of being deployed on the roof. The size information threshold is a size limit value set when determining whether the target object is suitable for being deployed on the roof of a vehicle, and can be determined based on factors such as the size of the vehicle, the space limit on the roof, and the size of the target object.

[0072] Optionally, by setting a size information threshold, effective judgment and decision-making can be made when deploying the target object, ensuring that the target object can be safely deployed on the roof of the vehicle while ensuring vehicle and driving safety.

[0073] Optionally, the size information threshold may be a height limit, which may determine whether the height of the target object exceeds the maximum height limit of the vehicle roof, so as to ensure that the target object does not collide with an overpass or other obstacles that are too low when deployed. It may be a width limit, which may determine whether the width of the target object exceeds the maximum width limit of the vehicle roof, so as to ensure that the target object can be safely placed on the roof of the vehicle without exceeding the width of the vehicle.

[0074] It should be noted that the selection of the above size information threshold is only for illustration and no specific limitation is made here.

[0075] In this embodiment, by judging whether the items meet the requirements for roof loading, feedback can be given to the user whether loading is allowed, and how to adjust the active suspension if the vehicle comfort is to be met after loading. This solves the technical problem of being unable to effectively control the active suspension in the vehicle and achieves the technical effect of effectively controlling the active suspension in the vehicle.

[0076] As an optional embodiment, step S104, when the size information meets the size information threshold and the target object has been deployed on the roof, in response to the vehicle being in a driving state, detect the road on which the vehicle is traveling, including: when the size information meets the size information threshold and the target object has been deployed on the roof, in response to the vehicle being in a driving state, using the vehicle's scanning equipment to detect road signs and / or obstacles on the road.

[0077] In this embodiment, when it is necessary to detect the road on which the vehicle is traveling, the scanning device of the vehicle can be used to detect the road signs and / or obstacles on the road when the size information meets the size information threshold, the target object is deployed on the roof, and the vehicle is in a driving state. The road signs can be road height warning signs. The obstacles can be height limit frames.

[0078] In this embodiment, by using the vehicle's scanning equipment to detect road signs and obstacles on the road, especially road height warning signs and height limit obstacles, the driver's perception and alertness of road conditions can be improved, ensuring that the vehicle passes through the road safely and stably during driving.

[0079] Optionally, the detection of road height warning signs and / or height limit frames can be performed by scanning with a scanning device mounted on the vehicle to remind the driver to pay attention to the height limit of the road. It is also possible to identify and detect height warning signs and / or height limit frames on the road through image recognition technology or laser radar scanning, and send corresponding warning information to the driver.

[0080] It should be noted that the above-mentioned detection methods of road height warning signs and / or height limit frames are only examples and are not specifically limited here. Any detection method that can be used to detect road height warning signs and / or height limit frames is within the protection scope of the embodiments of the present invention.

[0081] As an optional embodiment, the height threshold includes at least one of the following: an identification height threshold and an elevated height threshold, wherein, in response to detecting that the road is a target road, before determining the target height of the active suspension in the vehicle based at least on size information and the height threshold of the target road, the method also includes: in response to the road being identified as a height warning sign, and / or the obstacle including a road height limit frame, determining that the road is a target road; obtaining the identification height threshold from the height warning sign, and / or obtaining the elevated height threshold of the road height limit frame.

[0082] In this embodiment, before detecting that the road is a target road and determining the target height of the active suspension in the vehicle at least based on size information and a height threshold of the target road, the road can be determined to be the target road when the road sign is a height warning sign and / or the obstacle is a road height limit frame; and the sign height threshold is obtained from the height warning sign, and / or the elevation height threshold of the road height limit frame is obtained.

[0083] In this embodiment, the height threshold of the sign may be a height value obtained from a height warning sign, which is used to indicate the height limit on the road. The height threshold of the height-limited road frame may be a height value obtained from obstacles such as the height-limited road frame, which is used to indicate the height limit of the height-limited road frame or obstacles on the road.

[0084] Optionally, when the height of the vehicle exceeds the marked height threshold, the vehicle may be unable to pass through the height-restricted area on the road and may collide or be damaged. Therefore, the marked height threshold can be used to measure the degree of match between the height of the vehicle and the height limit of the road to ensure safe passage through the height-restricted area. When the height of the vehicle exceeds the height-restricted frame height threshold, the vehicle may collide or be blocked with the elevated frame or obstacles. Therefore, the elevated frame height threshold of the road height-restricted frame can be used to evaluate the degree of match between the vehicle and the height limit of the elevated frame or obstacles on the road to avoid unexpected events.

[0085] In this embodiment, the sign height threshold and the road height limit frame elevation threshold are obtained based on information such as height warning signs and road height limit frames, and the target road can be further identified and determined to ensure that the vehicle's active suspension system can intelligently adjust the suspension height according to actual road conditions, thereby improving driving safety and comfort.

[0086] As an optional embodiment, step S106, in response to detecting that the road is a target road, determines the target height of the active suspension in the vehicle based at least on the size information and the height threshold of the target road, including: obtaining the height adjustment range of the active suspension; determining the target height based on the size information, the height information of the vehicle body, the ground clearance of the vehicle body, the wheel diameter of the vehicle, the height adjustment range and the height threshold.

[0087] In this embodiment, in the process of determining the target height of the active suspension in the vehicle, the height adjustment range of the active suspension can be obtained, and the target height can be determined based on size information, height information of the vehicle body, ground clearance of the vehicle body, wheel diameter of the vehicle, height adjustment range and height threshold.

[0088] Optionally, the height adjustment range of the active suspension, that is, the maximum and minimum height ranges that the suspension system can adjust, can be determined by a vehicle control unit, a vehicle state monitoring sensor, a networked vehicle system, etc. The above-mentioned method for determining the height adjustment range of the active suspension is only for illustration and is not specifically limited here. As long as it is a method that can be used to determine the height adjustment range of the active suspension, it is within the protection scope of the embodiments of the present invention.

[0089] Optionally, the target height can be comprehensively calculated by an algorithm in the central processing unit, analyzing the relationship between the total height of the vehicle after the roof load and the height limit of the target road. If the estimated total height of the vehicle after the roof load exceeds the height threshold of the target road, a target height is calculated that ensures that the roof load can safely pass the target road without violating the height limit after considering the adjustment range of the active suspension.

[0090] For example, the target height can be determined by the following formula:

[0091] f(H)=∑f(H1, H2, H3, D1)*R

[0092] Among them, H1 can be used to indicate the height of the object, H2 can indicate the height information of the vehicle body, that is, the vehicle body height, H3 can indicate the height from the ground, D1 can indicate the wheel diameter, and R can indicate the height adjustment range of the active suspension, that is, the suspension height adjustment range.

[0093] In an embodiment of the present invention, by accurately obtaining the height adjustment range of the active suspension and comprehensively considering the various dimensional information of the vehicle, the target height can be determined to ensure that the vehicle will not collide or be damaged when passing through an area with height restrictions, thereby improving driving safety. According to the vehicle's body height information, ground clearance, wheel diameter and other parameters, combined with the height adjustment range and height threshold, determining a suitable target height can improve the driving comfort of the vehicle under different road conditions and reduce the vibration and discomfort of the suspension system. Based on the dimensional information and height threshold, the target height can be intelligently determined so that the active suspension system can automatically adjust the height according to the actual road conditions, improve the adaptability and stability of the vehicle, and reduce the operating burden of the driver. By comprehensively considering the vehicle's dimensional information and height restrictions, determining the target height can achieve more accurate suspension height adjustment, which can ensure that the vehicle can accurately adjust the height when passing through the height-restricted area to avoid collisions.

[0094] As an optional embodiment, before controlling the active suspension according to the control strategy corresponding to the target height, the method also includes: in response to the target height being greater than the identification height threshold and / or the elevated height threshold, sending a third prompt message to the terminal device of the vehicle, wherein the third prompt message is used to prompt that the vehicle cannot pass the target road by controlling the active suspension; controlling the active suspension according to the control strategy corresponding to the target height, including: in response to the target height being less than the identification height threshold and the elevated height threshold, adjusting the height of the active suspension to the target height according to the control strategy corresponding to the target height, so that the vehicle passes the target road.

[0095] In this embodiment, before the active suspension is controlled according to the control strategy corresponding to the target height, when the target height is greater than the identification height threshold and / or the elevated height threshold, a third prompt message may be sent to the terminal device of the vehicle, prompting that the vehicle cannot pass the target road by controlling the active suspension. When the active suspension is controlled according to the control strategy corresponding to the target height, when the target height is less than the identification height threshold and the elevated height threshold, the height of the active suspension may be adjusted to the target height according to the control strategy corresponding to the target height, so that the vehicle passes the target road.

[0096] For example, before adjusting the active suspension to adapt to the height requirement of the roof load, determine whether the target height f(H) exceeds the height limit threshold X of the road sign or the height limit threshold Y of the height limit frame. If the target height, that is, the total height of the vehicle required after the roof load is greater than the height limit threshold X of the road sign or the height limit threshold Y of the height limit frame, that is, f(H)>(X,Y), the height restriction will not be overcome by adjusting the suspension. Instead, a third prompt message is sent to the vehicle's terminal device, such as the in-vehicle infotainment system or the driver's smartphone. The prompt message can inform the driver that even if the suspension height is adjusted, the vehicle cannot safely pass the road restriction ahead, thereby avoiding invalid suspension adjustment operations and possible collision risks.

[0097] For another example, if the target height is less than the height limit threshold X of the road sign or the height limit threshold Y of the height limit frame, that is, f(H)<(X,Y). That is, within the permitted range of the road height limit, the active suspension can be adjusted according to the preset control strategy, and the most suitable suspension height can be calculated to ensure the safety of the load and the smooth passage of the vehicle through the height limit area, while maintaining the comfort and driving stability of the vehicle. Through this adjustment, the vehicle can maximize the convenience of roof loading while complying with relevant regulations.

[0098] In this embodiment, by introducing threshold judgment and intelligent feedback mechanism, not only the practicality and safety are enhanced, but also the user experience is improved, ensuring the vehicle's traffic capacity and cargo safety under various road height restrictions.

[0099] In an embodiment of the present invention, by acquiring the size information of a target object deployed on the roof of a vehicle, when the size information meets the size information threshold, the target object has been deployed on the roof, and the vehicle is in a driving state, the road on which the vehicle is traveling is detected. When the road is detected as the target road, the target height of the active suspension in the vehicle is determined based on the size information and the height threshold of the target road, and the active suspension is controlled according to the control strategy corresponding to the target height. The controlled active suspension can be used to make the vehicle pass through the target road. In this embodiment, by acquiring the size information of the target object to be deployed on the roof of the vehicle, it can be determined whether the size information meets the size information threshold. When the size information meets the size information threshold, and when the target object has been deployed on the roof, the road on which the vehicle is traveling can be detected when the vehicle is in a driving state. After detecting the road on which the vehicle is traveling, based on the size information and the height threshold of the target road, the target height of the active suspension in the vehicle can be determined, thereby controlling the active suspension to achieve the technical effect of effectively controlling the active suspension in the vehicle, solving the technical problem of being unable to effectively control the active suspension in the vehicle.

[0100] Another optional specific implementation is described in detail below.

[0101] At present, large-size off-road or sports utility vehicles (SUVs) are favored by the consumer market, and there is an increasing demand for vehicle loading capacity for self-driving travel, outings, camping and other leisure activities. Compared with loading items in the limited space inside the car, placing them on the roof through a shelf is more cost-effective. However, when placing items on the roof, when the vehicle encounters some height-restricted sections during driving, it is restricted by the height of the relevant roads and cannot safely pass through the height-restricted sections through active suspension adjustment.

[0102] In the embodiment of the present invention, vehicle cloud technology, visual recognition technology, and active suspension technology are comprehensively utilized. By comprehensively analyzing the size of the roof load, the vehicle body height, the height limit frame, etc., the top load of the vehicle is always kept within the height limit / safety range of the relevant road through HMI system reminders or through the intervention of the active suspension, thereby achieving the technical effect of ensuring that the vehicle with roof loads can safely pass through the height-restricted section by adjusting the active suspension, and solving the technical problem that the active suspension cannot be adjusted to ensure that the vehicle with roof loads can safely pass through the height-restricted section.

When the items are installed on the roof, facing the height limit frame of the road, it is impossible to judge whether they will collide or scratch, which poses a risk of damaging the items and making it impossible to safely pass through the height-restricted section.

[0105] Figure 3 is a schematic diagram of sending the size of an item to a vehicle through a terminal device according to an embodiment of the present invention, such as Figure 3 As shown, when a user purchases an item, the item size can be sent to the cloud 304 via the terminal device 302, and the cloud 304 then sends it to the vehicle 306. By analyzing whether the item meets the requirements for roof loading, the user is fed back whether it is allowed and how the active suspension will be adjusted to meet the vehicle comfort after loading.

[0106] Figure 4 FIG. 1 is a schematic diagram of a scanning device scanning an object according to an embodiment of the present invention. Figure 4 As shown, when the user is ready to load items, the user can also place the items in front of the vehicle. The on-board scanning equipment will scan the appearance of the items and analyze the size. Then, it will analyze whether the items meet the requirements for roof loading, and feedback will be given to the user whether it is allowed and how the active suspension will be adjusted to meet the vehicle comfort after loading.

[0110] The central processor 701 is used to receive and process data from the terminal device 702 and the scanning device 703, run and comprehensively analyze the passability of the roof after loading, and control the chassis controller 705 or feedback information through the human-machine interface system 704 according to the results.

[0111] The terminal device 702 may be a smart phone or a vehicle-mounted touch screen, and is used to input item size data through the terminal device 702 .

[0112] The scanning device 703 may be a camera, a millimeter wave radar, a laser radar, etc., which is used to identify and measure the size of objects, road height limit signs, the height of height limit racks, etc.

[0113] The HMI system 704 can be used to display system status and warning information to the user, and can also receive user instructions.

[0114] The chassis controller 705 can control the active suspension system and adjust the vehicle height according to the instructions of the central processor 701.

[0115] In the embodiment of the present invention, the object size data is input through the terminal device 702, and the object size, the road height limit sign, and the height of the height limit frame are identified and measured through the scanning device 703. When the height of the roof load is close to the height limit value, the central processor 701 sends a command to the chassis controller 705, and the chassis controller 705 adjusts the active suspension according to the vehicle state and road conditions to ensure safe driving within the height limit range. The current state is displayed to the user through the HMI system 704. If the active suspension cannot meet the passing requirements or relevant regulations, the user will be reminded through the HMI system 704, achieving the purpose of multi-modal interactive adjustment of the active suspension height, solving the technical problem that the active suspension cannot be adjusted to ensure that the roof-loaded vehicle can safely pass the height-restricted section, and achieving the technical effect of ensuring that the roof-loaded vehicle can safely pass the height-restricted section by adjusting the active suspension.

[0116] Figure 8(a) is a schematic diagram of an object scanning according to an embodiment of the present invention. As shown in Figure 8(a), when the vehicle is at a specified distance L, the object can be placed at the specified distance L from the front of the vehicle, and the height of the object can be scanned using a scanning device.

[0117] Figure 8(b) is a flow chart of a process for calculating the height of an object according to an embodiment of the present invention. As shown in Figure 8(b), after scanning the height of the object, a number of algorithms within the central processing unit are used to comprehensively calculate the height of the object input by the mobile phone or the scanning device to obtain a scanning point cloud result, and the central processing unit is used to perform point mapping and imaging to perform height calculation, thereby obtaining the size information of the object.

In addition, the height threshold for height limit sign recognition can be expressed as X, and the height threshold for height limit frame height can be expressed as Y, then the target height of the active suspension in the vehicle can be expressed as f(H)=∑f(H1, H2, H3, D1)*R. When f(H)>(X,Y), that is, the target height is greater than the height threshold of the height limit sign and the height limit frame height, it is indicated that the target road cannot be passed. When f(H)<(X,Y), that is, the target height is less than the height threshold of the height limit sign and the height limit frame height, the target road can be passed by automatically adjusting the suspension height.

[0120] In an embodiment of the present invention, the height of the item input by a mobile phone or the height of the item scanned by a scanning device is comprehensively calculated, calculated by a central processing unit, integrated with the height dimensions related to the vehicle, and compared with the height limit sign or the height limit frame. Finally, a difference analysis is performed with the adjustable range of the active suspension to obtain the passability result of the current roof load. When the control system based on the roof load and the active suspension height of the scanning device allows the suspension height to be adjusted, the suspension height is lowered or increased, or when the suspension height cannot be met, the user is promptly reminded through the HMI system to achieve the technical effect of effectively controlling the active suspension in the vehicle, thereby solving the technical problem of being unable to effectively control the active suspension in the vehicle.
