Description

Detection system and method for determining a horizontal attitude of a vehicle

Technical Field

The present disclosure relates to the field of data processing technologies, and in particular, to a detection system and method for determining a horizontal posture of a vehicle.

Background

Some specific types of vehicles, such as a motor home (especially a trailer) or a movable house, generally need to level a living compartment or a movable house of the motor home after parking so that a user can maintain a horizontal state while living in the living compartment or the movable house to enjoy a more comfortable living space.

The existing leveling modes mainly can be divided into two types, one type is that a leveling device (such as an electric push rod, a jack and the like) is arranged when a motor home or a movable house leaves a factory, the purpose of leveling can be achieved by controlling the leveling device, and even part of vehicles are provided with an automatic leveling system without manual control of the leveling device by a user. The other is that the motor home or the movable house is not provided with a leveling device, and a user needs to fill a leveling cushion block below a tire or a supporting leg at the lower position of the car body to adjust the horizontal state of the car body so as to achieve the purpose of leveling.

In the second adjustment process, the user needs to fill the leveling pad under the corresponding wheel outside the vehicle, and then drive the vehicle in the cockpit to continuously fine-tune the position of the vehicle body until the vehicle body completely reaches a horizontal state. This adjustment process requires the user to repeatedly enter and exit the cockpit a plurality of times to observe and confirm the state of the vehicle body and adjust the position of the vehicle, is tedious and time-consuming for the user, and also requires much physical effort. There are also some detection devices for prompting the user of the horizontal state of the vehicle body, so that the user can more intuitively and effectively observe the horizontal state of the vehicle by additionally installing the detection device on a motor home or a movable house which is not provided with the leveling device when leaving the factory. For example, a vehicle level state detection device commonly used at present is a traditional two-dimensional bubble level, and a user usually installs the bubble level in a living carriage or a movable house of a motor home so as to feed back the level state of a current vehicle body in real time. However, since the user needs to drive the vehicle in the cockpit while leveling the vehicle, and the bubble level is installed in the living carriage of the caravan, for most caravans, especially the trailer-type caravans, the user cannot observe the bubble level in the cockpit, and therefore, the user still needs to repeatedly get in and out of the cockpit to observe the state of the vehicle body, that is, the problem of the tedious, time-consuming and laborious pain point in the leveling process is still not well solved, and the user experience is poor.

Examples

Fig. 1 is a schematic diagram of a detection system for determining a horizontal posture of a vehicle according to an embodiment of the present application, where the embodiment may be suitable for an application scenario in which horizontal posture detection is performed on a vehicle that needs leveling, and the system may be implemented in a form of hardware and software. As shown in fig. 1, the system includes: a level detecting device 110 provided to at least one mounting surface of the vehicle for determining inclination angle data of at least a part of the vehicle in a first direction and a second direction perpendicular to the first direction; at least one interactive display terminal 120, communicatively coupled to the level detection means, is adapted to acquire and process the tilt angle data and display at least one interface element associated with the tilt angle data to instruct a user to level a corresponding portion of the vehicle based on the interface element.

The vehicle in the application scenario for which the present embodiment is aimed is a vehicle that requires a user to perform manual leveling when in use, and is not a vehicle that is capable of performing automatic leveling from a vehicle body leveling system (or leveling device) when leaving the factory. Typically, this embodiment is directed to, for example, a motor home or a mobile house, and after parking, a motor home, particularly a trailer-type motor home, even if a tractor is parked on a level ground, a living car may still be parked on an inclined ground and needs to be leveled; similarly, after a mobile house is towed to a camp by a tractor, there is also a need for leveling the house while it is in use on the floor. In order to enable a user to accurately identify the horizontal state of the vehicle without being limited by the location of the user when leveling the vehicle, the system of the present embodiment includes a horizontal detection device 110, and the horizontal detection device 110 is disposed on at least one mounting surface of the vehicle. Specifically, at least one installation surface of the vehicle refers to a surface that can reflect a current tilting state of the vehicle, and as an example, the level detection device 110 may be installed at a planar position in a living compartment of the car as a car interior wall surface of the car as a car.

The level detecting device 110 is configured to obtain inclination angles of at least a portion of the vehicle in multiple directions when the vehicle is parked, where the level detecting device 110 may include at least one inclination detecting sensor, and after the level detecting device 110 is disposed on an installation surface of the vehicle, the inclination detecting sensor may obtain inclination angle data in two mutually perpendicular directions of the installation surface, where the inclination angle data may reflect an inclination state of the vehicle at a current moment. As an alternative embodiment, the tilt detection sensor may be implemented using a multi-axis sensor, which may typically include a three-axis sensor, a six-axis sensor, and the like. Further, the level detecting device 110 is configured to determine inclination angle data of the mounting surface in a first direction and a second direction perpendicular to the first direction, where the first direction may be a driving direction of the vehicle, and correspondingly, the second direction may be a direction of the vehicle body on the left and right sides of the vehicle. Correspondingly, the tilt angle data in the first direction is a pitch angle of the vehicle reflecting an angle between the first direction of the vehicle and the horizontal plane; the tilt angle data in the second direction is a roll angle of the vehicle reflecting an angle between the second direction of the vehicle and the horizontal plane. The first direction and the second direction are not limited to this, as long as the pitch angle and the roll angle of the vehicle can be reflected, and the specific direction is not limited here.

The detection system in this embodiment further includes at least one interactive display terminal 120, which typically may be at least one of a smart phone of the user, a smart wearable device (e.g., a smart watch, etc.), and a vehicle-mounted display screen in the cockpit. The interactive display terminal 120 includes a communication module and at least one display panel, and the communication module may be used to communicate with the level detection device 110, thereby acquiring and processing the tilt angle data from the level detection device 110. The interactive display terminal 120 further includes at least one display panel on which at least one interface element associated with the tilt angle data may be displayed so that the interface element may be retrieved from the display panel by a user. The interactive display terminal also comprises a processor, wherein the processor is used for processing the inclination angle data acquired from the horizontal detection device to obtain interface elements related to the inclination angle data, and the interface elements can visually represent the elements more intuitively for the inclination state of the vehicle. Therefore, the user is not limited by the position of the user when driving the vehicle to level, and the horizontal state of the current vehicle can be acquired through the interactive display terminal 120 at any place, so that the user can be guided to better adjust the height of the corresponding part of the vehicle to reach the horizontal state, and the problem of tedious, time-consuming and labor-consuming pain points in the process of the original leveling mode is solved.

For example, as shown in fig. 2, which is an architecture diagram of another detection system for determining a horizontal posture of a vehicle, the horizontal detection device 110 includes a sensor, a processor, and a communication module, and when the horizontal detection device is initially installed, the system is powered on, the sensor may be used to detect inclination angle data of at least a portion of the vehicle in a first direction and a second direction, and send the inclination angle data to the processor for filtering and arithmetic processing, and the communication module sends the inclination angle data processed by the processor to the interactive display terminal 120.

Optionally, the level detecting device 110 is provided with a printed circuit board PCB, on which at least one sensor, a processor, and a communication module are integrated. The level detecting device 110 further includes a display panel connected to the PCB, so that the processor can display information such as tilt angle data through the display panel. Further, raw tilt angle data of at least a part of the vehicle in a first direction and a second direction perpendicular to the first direction is acquired through at least one sensor, the raw tilt angle data is preprocessed by a processor and then displayed on a display panel of the level detection device 110, that is, the tilt state of the vehicle can be visually displayed through the level detection device 110 itself, and the processed tilt angle data is sent to the interactive display terminal 120 through a communication module. Optionally, the preprocessing performed by the processor may include filtering and calculating the raw tilt angle data, for example, the raw tilt angle data is processed by using a kalman filtering fusion method in the processor to obtain processed tilt angle data, so that the tilt angle data obtained by the sensor can more accurately reflect the horizontal state of the vehicle.

Optionally, the level detecting device 110 further includes a communication module, and establishes a communication connection relationship with the communication module in the interactive display terminal, and the level detecting device sends the acquired tilt angle data to the interactive display terminal through the communication module. Further, the communication module may adopt a wired communication mode or a wireless communication mode, the wired communication mode may be CAN or RS485, and the wireless communication mode may be a communication mode such as bluetooth, zigbee, wi-Fi, 3G/4G/5G, or a combination thereof, and the communication mode adopted in the communication module in the embodiment of the present application is not limited. Preferably, the level detection device 110 and the interactive display terminal 120 communicate wirelessly, so that the user can not be limited to the location using the interactive display terminal 120 in a mobile scene, for example, when the interactive display terminal 120 is a mobile phone of the user, it is preferable to communicate with the level detection device 110 through bluetooth or Wi-Fi, so that the user can grasp the tilting state of the vehicle in real time through the mobile phone, both in the cockpit and around the vehicle.

In the detection system of the present embodiment, the number of the interactive display terminals 120 is not limited to 1, for example, the interactive display terminals 120 may be a plurality of intelligent terminals, such as a terminal combination of a smart phone and a vehicle-mounted display screen in a cockpit, or a terminal combination of a smart phone and a smart wearable device, or a terminal combination of a mobile phone and a monitoring display screen installed in a car as a house, and the present embodiment is not limited to a specific intelligent terminal. The interactive display terminal 120 includes a communication module, a processor, and at least one display panel, and communication can be performed between the interactive display terminal 120 and the level detection device 110, preferably, wireless communication can be performed between the interactive display terminal 120 and the level detection device 110, so that the interactive display terminal 120 can obtain tilt angle data more flexibly in a mobile scenario. And after the communication module receives the inclination angle data, the processor processes the inclination angle data to obtain interface elements corresponding to the inclination angle data, and the interface elements are displayed in the display panel. The user can directly acquire the current tilting state of the vehicle in the cockpit through the interactive display terminal 120, and directly perform the leveling operation on the vehicle by moving and adjusting the vehicle position. Or, the user can directly fill the leveling cushion block or raise the corresponding part (such as a tire, a jack and the like) of the vehicle according to the interface element displayed on the device outside the carriage through the interactive display terminal 120, the inclined state does not need to be observed in the carriage and then the vehicle is taken out of the carriage for adjustment, or two persons are required to be matched for leveling, the leveling efficiency is improved, the leveling process of the user is simpler and more effective, and the user experience is improved.

In one possible embodiment, the interface element comprises at least one of tilt angle data, a vehicle picture characterizing a tilt state of the vehicle, and a target adjustment parameter characterizing a need for the vehicle to reach a level state, wherein the target adjustment parameter comprises a target adjustment height and/or a target adjustment direction.

In this embodiment, in order to enable the user to more intuitively know the current inclination state of the vehicle and/or which positions of the vehicle need to be adjusted and/or the direction and height of the corresponding positions of the vehicle need to be adjusted, the interface elements displayed by the interactive display terminal 120 are specifically designed to improve the user interaction experience. Therefore, after the interactive display terminal 120 acquires the tilt angle data, the display interface of the interactive display terminal 120 may display at least one interface element including the tilt angle data, a vehicle picture representing a tilt state of the vehicle, and a target adjustment parameter required for representing that the vehicle reaches a horizontal state, so as to instruct a user to horizontally adjust a corresponding portion of the vehicle according to the interface element. The interface elements may be displayed and output by a software interaction interface of the interactive display terminal 120, and a user may obtain the corresponding interface elements by accessing a corresponding interaction interface of the software.

Specifically, as an alternative embodiment, the interactive display terminal 120 may directly display the tilt angle data, so that the user can intuitively know the tilt angle of the current vehicle through the interactive display terminal 120.

As another alternative embodiment, the interactive display terminal 120 may display a vehicle picture representing a tilting state of the vehicle, the tilting of the vehicle picture corresponding to the size of the tilt angle data, i.e., the larger the tilt angle, the more tilted the displayed vehicle picture. For example, as shown in fig. 3, photographs of a vehicle in different tilt states are displayed for a graphical user interface of the interactive display terminal 120, which show a tilt state of a vehicle body in a front-rear direction and a tilt state of the vehicle body in a left-right direction, respectively, and a degree of tilt is matched with tilt angle data of at least a part of the vehicle in a first direction and a second direction, and when the tilt angle data is larger, a vehicle picture is displayed more obliquely. When the vehicle remains horizontal in both different directions, then the corresponding vehicle picture is also displayed horizontally. Alternatively, the vehicle picture may be represented by an electronic bubble map matching the model of the vehicle, with a deviation of the bubble indicating that the vehicle is tilted. Fig. 4 is a schematic view showing the effect of using the electronic bubble chart to represent the vehicle tilting state in the vehicle picture.

As still another alternative embodiment, the interactive display terminal 120 may further display a target adjustment parameter, where the target adjustment parameter may be a target adjustment height and/or a target adjustment direction obtained according to the tilt angle data, where the target adjustment height indicates a height value that needs to be adjusted when the vehicle corresponding position reaches the horizontal state, and the target adjustment direction indicates a direction that needs to be adjusted when the vehicle corresponding position reaches the horizontal state. The specific target adjustment height and target adjustment direction may be determined according to the tilt direction corresponding to the tilt angle data, and are not particularly limited herein. The user can clearly know what direction the corresponding position of the vehicle needs to be adjusted and how much height the corresponding position of the vehicle needs to be adjusted according to the displayed target adjusting parameters, and accordingly proper quantity of leveling cushion blocks can be accurately selected for leveling.

It should be noted that, the above three embodiments may be implemented separately or may be implemented after combination, so that the human-computer interaction experience of the user may be further improved. Taking the embodiment shown in fig. 3 as an example, it shows not only tilt angle data in the front-rear direction and the left-right direction of the vehicle, but also a vehicle picture representing the tilt state of the vehicle. Thus, according to the vehicle tilting state shown in the left diagram of fig. 3, the user can intuitively know that the two rear wheels and the right front wheel of the vehicle need to be raised to achieve the leveling purpose, and the right diagram of fig. 3 shows the display interface after leveling, because the vehicle is in the horizontal state in both directions, the user can intuitively know that the current vehicle is already in the horizontal state. Taking the embodiment shown in fig. 4 as an example, a vehicle picture representing the inclination state of the vehicle and a target adjustment parameter required for representing the vehicle reaching the horizontal state are displayed at the same time, and meanwhile, the vehicle picture is matched with the vehicle type of a user, for example, the left diagram in fig. 4 shows an electronic bubble diagram of a four-wheel motor home (4-wheel RV), and the inclination degree of the corresponding position of the current vehicle, the target height and the target direction required to be adjusted can be known according to the position of the bubble and the height value and the arrow near the corresponding position of the vehicle. The right hand view in fig. 4 shows an electronic bubble diagram of a travel trailer (caravan) with a height adjustable jack parking support at the towing position, and likewise, the inclination of the corresponding position of the current vehicle and the target height and target direction to be adjusted can be known according to the height value and arrow of the bubble at the position and near the corresponding position of the vehicle. Therefore, man-machine interaction information can be provided for the user in a more visual mode, and the user can be assisted in leveling the vehicle more efficiently.

Alternatively, when the level detecting device 110 is mounted on at least one mounting surface of the vehicle, the mounting direction of the level detecting device 110 coincides with the first direction and the second direction, thereby accurately reflecting inclination angle data of the vehicle in the first direction and the second direction. For example, in the first embodiment, the level detecting device 110 may be mounted on a vertical wall surface facing away from the cabin, the acquired tilt angle data in the first direction may be tilt angle data in the left and right directions of the vehicle with respect to the horizontal plane, and the tilt angle data in the second direction may be tilt angle data in the front and rear directions of the vehicle with respect to the horizontal plane. In the second embodiment, the horizontal detecting device 110 may be mounted on a vertical wall surface facing the cabin on the front surface, the acquired inclination angle data in the first direction may be inclination angle data of the left and right sides of the vehicle with respect to the horizontal plane, and the inclination angle data in the second direction may be inclination angle data of the front and rear direction of the vehicle with respect to the horizontal plane; since the mounting direction is exactly opposite, the absolute values of the tilt angle data obtained in the two embodiments are identical and opposite, compared to the first embodiment. In the third embodiment, the horizontal detecting device 110 may be mounted on a vertical wall surface facing the right-side vehicle body of the vehicle, the acquired inclination angle data of the first direction may be inclination angle data of the vehicle front-rear direction with respect to the horizontal plane, and the inclination angle data of the second direction may be inclination angle data of the vehicle left-right direction with respect to the horizontal plane. In the fourth embodiment, the horizontal detecting device 110 may be mounted on a vertical wall surface facing the left body of the vehicle from the front, the acquired inclination angle data in the first direction may be inclination angle data of the vehicle in the front-rear direction with respect to the horizontal plane, and the inclination angle data in the second direction may be inclination angle data of the vehicle in the left-right direction with respect to the horizontal plane; similarly, the absolute values of the inclination angle data obtained in the two embodiments are the same and opposite to each other due to the exactly opposite mounting directions, as compared with the third embodiment. Alternatively, the installation position and the installation direction of the level detection device 110 are not limited to the above-described four embodiments, and it is understood by those skilled in the art that inclination angle data of at least a portion of the vehicle in a first direction and a second direction perpendicular to the first direction can be determined by a geometric conversion relationship based on the determined installation position.

In an alternative embodiment, the interactive display terminal 120 is further configured to display installation guide information for instructing a user to set the level detection device to at least one installation surface of the vehicle after the vehicle is driven to the horizontal plane.

Specifically, before the level detecting device 110 is installed on at least one installation surface of the vehicle, it is required to ensure that the vehicle is parked on a horizontal plane, otherwise the level detecting device may be installed obliquely with respect to the horizontal plane, which may result in inaccuracy of inclination angle data acquired by the subsequent level detecting device, and thus inaccuracy of leveling indication information. If the user is not reminded, the user may ignore the point, so that before the user installs the level detection device, the interactive display terminal displays installation guide information to remind the user to install the level detection device after the vehicle is driven to the horizontal plane.

Accordingly, the interactive display terminal 120 outputs a prompt message prompting the user to drive the vehicle to the horizontal plane at the time of initial installation. Meanwhile, the level detecting device 110 is embedded with a two-dimensional bubble level, and a user can ensure that the level detecting device 110 is horizontally installed according to the two-dimensional bubble level when installing the level detecting device 110.

In a further alternative embodiment, the installation guide information is further used for prompting the user to place the interactive display terminal in any one of the opposite horizontal surfaces of the vehicle, so as to determine whether the current vehicle is on the horizontal plane and/or update the installation guide information correspondingly according to the current inclination state of the vehicle acquired by the interactive display terminal.

As described above, the user needs to ensure that the vehicle is parked on a horizontal plane before installing the level detection device 110. However, it is difficult for the user to determine whether the current vehicle is parked on a level ground. The interactive display terminal 120 itself in this embodiment is provided with a tilt angle detection sensor, for example, when the interactive display terminal 120 includes a smart phone, an acceleration sensor and/or an electronic gyroscope of the smart phone can be used to evaluate the current tilt state of the smart phone, so that the current level state of the vehicle can be calibrated by using the sensor data of the smart phone. Specifically, the installation guide information displayed by the interactive display terminal 120 may also prompt the user to place the interactive display terminal 120 in any one of the opposite horizontal surfaces of the vehicle, for example, the installation guide information may prompt the user to place the smart phone flat on the floor surface or the dining table surface of the caravan, then the inclination angle of the opposite horizontal surface may be obtained by the inclination angle detection sensor of the interactive display terminal 120, and if it is confirmed that the opposite horizontal surface is currently horizontal, the installation guide information may be updated to indicate that the user may currently install the horizontal detection device 110; if it is confirmed that the relative horizontal surface is currently inclined, the installation guide information may be updated to indicate that the user needs to continue driving the vehicle to the horizontal ground.

As another optional implementation manner, the interactive display terminal 120 includes a smart phone and a vehicle-mounted display screen in a cockpit, different terminals in the interactive display terminal can communicate with each other, before installing the horizontal detection device, installation guide information is displayed on the smart phone and the vehicle-mounted display screen, a user is reminded to place the smart phone on any one of opposite horizontal surfaces of the vehicle, the user is reminded to drive the vehicle to the horizontal ground, the inclination state of the smart phone in the current state is acquired through a sensor in the smart phone and is used for representing the inclination state of the current vehicle, the current inclination state is sent to the vehicle-mounted display screen, a driver can directly acquire whether the current vehicle is stopped on the horizontal plane through the vehicle-mounted display screen, and if the current inclination state is no inclination or the inclination angle is smaller than a preset angle, the user is reminded of installing the horizontal detection device; if the current vehicle is in the inclined state according to the inclination angle of the mobile phone, the user is reminded of continuously driving the vehicle to the horizontal ground to install the horizontal detection device.

In an alternative embodiment, the interactive display terminal 120 is further configured to dynamically adjust at least one interface element associated with the tilt angle data in response to a change in the acquired tilt angle data.

In this embodiment, the level detecting device 110 periodically obtains the tilt angle data according to a preset time interval during the leveling process of the vehicle or during the driving process of the vehicle, if the current tilt angle data is the same as the tilt angle data obtained in the previous time interval, the tilt angle data change information is not sent to the interactive display terminal, or the interactive display terminal 120 maintains the interface element displayed in the previous time interval. If the inclination angle data change information is different, the inclination angle data change information is sent to the interactive display terminal 120, and after the interactive display terminal 120 receives the inclination angle data change information, the interface element is updated and displayed according to the changed inclination angle data, so that the real-time performance and accuracy of representing the vehicle inclination state by the interface element acquired by the user through the interactive display terminal are ensured. For example, when the user manually levels the caravan, the man-machine interaction interface of the smart phone can display the latest vehicle inclination state in real time so as to prompt the user whether the vehicle is being leveled in the correct direction.

According to the technical scheme, through the configuration of the interactive display terminal 120 communicated with the horizontal detection device 110 in the detection system, the interactive display terminal 120 displays the interface elements related to the inclination angle data detected by the horizontal detection device 110, and a user can adjust the horizontal posture of the vehicle through the interactive display terminal, so that the problems of complex process, time and labor waste when the user levels the vehicle are solved, and the leveling efficiency and the user experience are improved.

Based on the embodiment, the interface elements displayed by the interactive display terminal are further optimized. Specifically, the detection system includes:

a level detecting device 110 provided to at least one mounting surface of the vehicle for determining inclination angle data of at least a part of the vehicle in a first direction and a second direction perpendicular to the first direction; at least one interactive display terminal 120, communicatively coupled to the level detection means, is adapted to acquire and process the tilt angle data and display at least one interface element associated with the tilt angle data to instruct a user to level a corresponding portion of the vehicle based on the interface element.

The interactive display terminal is used for determining target adjustment parameters required for representing the vehicle to reach a horizontal state according to the inclination angle data and the wheelbase parameters of the vehicle so as to instruct a user to horizontally adjust the corresponding part of the vehicle according to the target adjustment parameters.

In this embodiment, the wheelbase parameter of the vehicle is important parameter information for determining the target adjustment height, and the wheelbase parameter may include a front-rear wheelbase parameter and a left-right wheelbase parameter, and the wheelbase parameter may be determined by a user directly input or according to attribute information of the vehicle.

Specifically, the tilt angle data includes a tilt direction and a tilt angle, and when determining the target adjustment height, it is necessary to determine a wheelbase parameter in a corresponding direction according to the tilt direction, and determine the target adjustment height in the direction according to a relationship between the wheelbase parameter and the tilt angle.

For example, an x-axis is established in the left-right direction of the vehicle, a y-axis is established in the front-rear direction, the positive direction of the x-axis is the right direction, the positive direction of the y-axis is the front direction, the inclination angle data comprises an inclination angle theta of the x-axis and an inclination angle alpha of the y-axis, the front-rear wheelbase parameter of the vehicle is L2, the left-right wheelbase parameter is L1, and the target adjustment heights of the four wheel position points can be determined according to the inclination angle data and the wheelbase parameter.

In a possible embodiment, the interactive display terminal is further configured to determine wheelbase parameters of the vehicle from a database according to vehicle type information of the vehicle input by a user, where the database stores vehicle type information of a plurality of candidate vehicles and candidate wheelbase parameters corresponding to the vehicle type information; or the interactive display terminal is also used for determining the wheelbase parameter of the vehicle according to the wheelbase parameter input by the user, and the wheelbase parameter input by the user is measured by the user according to the wheelbase measurement and input guide information displayed on the interactive display terminal and is input into the interactive display terminal.

In this embodiment, the wheelbase parameter of the vehicle may be determined according to the vehicle type information of the vehicle input by the user through the database, or the wheelbase parameter may be directly input by the user through the interactive display terminal.

The method for determining the wheelbase parameters according to the vehicle type information of the vehicle input by the user can be accessed into a pre-configured vehicle type information database, and the vehicle type information of various candidate vehicles and the candidate wheelbase parameters corresponding to the vehicle type information are pre-stored in the database, wherein the database can be a pre-configured database locally on the interactive display terminal 120 or a cloud database accessed through networking. And the stored information in the database can be dynamically updated in real time in a linked manner to ensure the integrity of the coverage of the candidate vehicles in the database, and the user can determine the wheelbase parameters corresponding to the vehicle model by selecting the corresponding vehicle manufacturer brand and vehicle model through the man-machine interaction interface of the interaction display terminal 120. In the embodiment, a user does not need to manually and practically measure own vehicle wheelbase parameters, and the acquired data directly come from a vehicle manufacturer, so that the data are more accurate and effective.

In the method that the wheelbase parameter is directly input by the user through the interactive display terminal, the measurement is irregular due to the fact that the user performs measurement by himself, so that in order to ensure the accuracy of determining the target adjustment parameter, the wheelbase measurement and the input guide information are displayed in the interactive display terminal to instruct the user to measure the wheelbase parameter according to the wheelbase measurement and the input guide information and input the wheelbase parameter into the interactive display terminal. Fig. 5 is a schematic diagram showing the display effect of the wheelbase measurement and the input of the guidance information. Wherein L1 represents left and right wheelbase parameters, L2 represents front and rear wheelbase parameters, ellipse represents wheel position, and vehicle pictures in wheelbase measurement and input guiding information can be obtained through a database, namely, the database stores various candidate vehicle type information and vehicle pictures corresponding to the vehicle type information.

Specifically, a user can input vehicle type information of a vehicle through an interactive display terminal, firstly, the vehicle type information is queried through a database, whether the vehicle type information is stored in a wheel base parameter corresponding to the vehicle type information or not is determined, and if the vehicle type information is stored in the database, the wheel base parameter is directly obtained; and if not, displaying the wheelbase measurement and input guide information through the interactive display terminal so as to instruct a user to measure the wheelbase parameters according to the wheelbase measurement and input guide information and input the wheelbase parameters into the interactive display terminal.

In one possible embodiment, the target adjustment parameter includes a target adjustment height corresponding to a plurality of candidate location points of the vehicle; accordingly, determining a target adjustment parameter required to characterize the vehicle to reach a level state based on the tilt angle data and the wheelbase parameter of the vehicle, comprising: determining the highest position point in a plurality of candidate position points of the vehicle as a leveling reference point according to the inclination angle data, and determining the target adjustment height of the leveling reference point to be zero; and determining target adjustment heights of other candidate position points according to the inclination angle data.

In this embodiment, the candidate position points refer to position points in the vehicle where leveling can be provided, such as the wheel positions of the vehicle or fixed position points where the height adjustment device is installed. When the target adjustment height is determined, the highest position in all candidate position points is determined to be the leveling reference point according to the inclination angle data, namely, the heights of other candidate position points are adjusted to the height of the leveling reference point, so that leveling can be realized, the target adjustment height of the leveling reference point is 0, and no height adjustment is needed. And meanwhile, determining target adjustment heights of other candidate position points according to the inclination direction and the inclination angle corresponding to the inclination angle data, wherein the other candidate position points are position points except for the leveling reference point in all the candidate position points.

For example, as shown in fig. 6, which is a schematic diagram for determining the target adjustment height, referring to fig. 6, four wheel positions corresponding to W1 to W4 are candidate position points, an x-axis is established in the vehicle front-rear direction, a y-axis is established in the left-right direction, an x-axis positive direction is a front direction, an y-axis positive direction is a right direction, and the inclination angle data includes an inclination angle θ in the x-axis direction and an inclination angle α in the y-axis direction. The left-right wheelbase parameter of the vehicle is L1, the front-rear wheelbase parameter is L2, the highest point around W2 is W1-W4 according to the inclination angle, and the leveling reference point is set, so that the target adjustment height h1=l2×sinθ corresponding to the W1 point, the target adjustment height h3=l2×sinθ+l2×sinα corresponding to the W3 point, and the target adjustment height h4=l1×sinα corresponding to the W4 point. When the level detecting device is installed at other positions, the directions corresponding to the inclination angles are different, and then the calculation formulas of the target adjustment heights of the corresponding candidate position points are different, so that the calculation formulas of the target adjustment heights of the candidate position points are derived by a person skilled in the art according to the example calculation modes of the target adjustment heights, and are not repeated herein.

In an optional embodiment, the interactive display terminal is further configured to acquire installation orientation information of the level detection device in the vehicle cabin;

accordingly, determining a target adjustment height for other candidate location points based on the tilt angle data includes:

Determining the inclination direction corresponding to the inclination angle data according to the installation orientation information;

and determining target adjustment heights of other candidate position points according to the inclination direction and the inclination angle data.

In this embodiment, since the different installation directions of the horizontal detection device 110 may result in different inclination directions corresponding to the inclination angles in the detected inclination angle data, before determining the target adjustment height, it is further necessary to obtain installation orientation information of the horizontal detection device 110 in the cabin, where the installation orientation information may be obtained by inputting by the user in the interactive display terminal 120.

For example, after displaying that the vehicle is currently in the horizontal plane in the installation guiding information, the user is prompted to install the horizontal detection device and provide at least two types of candidate installation orientation information, as shown in fig. 7, which is a schematic view of installation selection for displaying candidate installation orientation information in the interactive display terminal, the P1 corresponding horizontal detection device faces the cabin away from the front, the P2 corresponding front faces the cabin, the P3 corresponding front faces the left side of the vehicle, and the P4 corresponding front faces the right side of the vehicle. And the user installs the horizontal detection device in the carriage according to the installation selection schematic diagram, and inputs the installation orientation information corresponding to the final installation into the interactive display terminal.

After the interactive display terminal acquires the installation orientation information and the inclination angle data, determining an inclination direction corresponding to the inclination angle, so as to determine the target adjustment height according to the inclination direction. For example, on the basis of the above example, if the installation orientation information is that the front surface corresponding to the P4 level detection device faces the right side of the vehicle, the obtained inclination direction corresponding to the inclination angle θ is along the front direction of the vehicle, the inclination direction corresponding to the inclination angle α is along the right direction of the vehicle, W2 is determined to be the highest point around W1 to W4 according to the inclination direction, and the leveling reference point is set, where the target adjustment height h1=l2×sinθ corresponding to the W1 point, the target adjustment height h3=l2×sinθ+l2×sinα corresponding to the W3 point, and the target adjustment height h4=l1×sinα corresponding to the W4 point. The calculation formula for the target adjustment height corresponding to the other installation orientation information can be derived by a person skilled in the art according to the method, and is not described in detail in this embodiment. Optionally, a calculation method of the target adjustment height corresponding to each candidate installation orientation information is set in advance in a processor in the interactive display terminal, and after the user inputs the corresponding installation orientation information, the target adjustment height is calculated according to the corresponding calculation method.

In one possible embodiment, the target adjustment parameters include a target adjustment height and a target adjustment direction for a plurality of candidate location points of the vehicle;

accordingly, the interactive display terminal displays at least one interface element related to the tilt angle data, including:

and displaying the target adjustment heights and the target adjustment directions of the candidate position points at picture positions corresponding to the candidate position points in vehicle pictures of the vehicle, and visually displaying the vehicle pictures to a user.

In this embodiment, in order to achieve better man-machine interaction effect, the user can conveniently level, in the display interface of the interactive display terminal 120, the target adjustment parameters are displayed at the positions of the pictures corresponding to the candidate position points, so that the user can conveniently and intuitively obtain the adjustment direction and/or height information corresponding to the positions of the vehicles to be leveled according to the pictures of the vehicles. In order to enable a user to intuitively know the current inclination condition of the vehicle and the height of the vehicle body to be adjusted, after the interactive display terminal obtains the inclination angle data and calculates the target adjustment height, the interactive display terminal displays corresponding contents through a display screen of the interactive display terminal, and displays corresponding target adjustment parameters at the picture positions corresponding to the candidate position points on the vehicle picture, as shown in an effect schematic diagram of display interface elements, and the current overall inclination state of the vehicle, the target adjustment height of the candidate position points of the vehicle and the inclination angle data are displayed in the figure.
