DETAILED DESCRIPTION OF THE INVENTION

[0032] Generally described, aspects of the present application relate to an adjustable suspension system. More specifically, one or more aspects of the present application provide a method for determining a suspension mode based on the determined suspension mode. This corresponds to a system that dynamically manages the vehicle's individual suspension settings. The system receives user input regarding a desired or specific suspension mode. For example, the user may select a vehicle through a user interface that presents the vehicle or The mode is selected through a separate interface generated on the communicating mobile device. The system may then receive the current speed, position, ground clearance measurements, vehicle status, and related to the vehicle or the environment around the vehicle, including the vehicle's status and historical information about previous measurements Acquire (or continuously acquire) sensor inputs corresponding to or resulting from measurements. (gain)

[0033] The system adjusts the suspension motion based on user input and acquired sensor input. Illustratively, the suspension system may include a controllable component. Bellows or straps that can be individually controlled by specifying a value or command for each For example, a vehicle may have multiple components, such as a wheel and a It has four individually controllable components that correspond to the suspension components. According to an aspect of the present application, the determined suspension mode may be These multiple controllable components can be increased, decreased, or maintained at their current setpoints. This includes specifying or changing the individual values ​​of the components. (e.g. dump mode) requires multiple In another embodiment, the second The mode (e.g. tilt mode) has two controllable components corresponding to the rear wheels of the vehicle. Lower the control element and raise the two controllable components corresponding to the front wheels of the vehicle. This may correspond to achieving a particular angle between the rear end of the vehicle and the ground. In another embodiment, the third mode (e.g., the nominal mode) may be configured to operate on a particular type of road or condition. to effectively lower the vehicle height to a selected threshold point to move the vehicle at To achieve this, multiple controllable components may be pulled down. In an embodiment, a fourth mode (e.g., horizontal mode) selects a selected height for the vehicle and then The four controllable parts may be individually adjusted so that the surface is approximately horizontal. The adjustment involves raising or lowering one or more controllable parts, especially in uneven ground environments. This may include the possibility of dropping the

[0034] The system provides various effective suspension modes that can be activated based on the determined suspension mode. For example, the system may take into account speed, vehicle conditions (e.g. The decision is made based on sensor data such as whether the front door is open, whether the rear door is open, etc. There are various actions that can be taken into consideration to prevent the execution of the suspension mode. In another embodiment, the system may be configured with a control rule to change the suspension settings. Validation from a user or system administrator who presents delegated or established authority to After that, the system will prevent switching to the running state, Modifications to controllable components or vehicle functions, for example, activating a brake, activating a camera, etc. Send or make changes to vehicle settings, such as making other changes to driving It is possible.

[0035] In accordance with aspects of the present application, a truck, a particular suspension system, and a value of the suspension system related values ​​(e.g., values ​​of controllable components), and suspension modes, Although described with respect to vehicles, those skilled in the art will recognize that reference to these embodiments is in fact illustrative. It will be understood that the foregoing is illustrative and should not be construed as limiting.

[0036] As mentioned above, vehicles have some form of suspension system. Height adjustment beyond the typical operating range (e.g., the specified air suspension operating range) When adjustments are made to the vehicle suspension system, the chassis, drivetrain, battery, doors, and gauges are Damage to various vehicle features such as uneven terrain or obstacles such as curbs Potential environmental conditions, such as hazards, can add to these risks. For example, in a vehicle with a conventional height adjustment mechanism, the bottom of the vehicle may be touched to an obstacle such as a rock or curb. It is possible that the vehicle height has been lowered in a way that allows contact. Operating the vehicle while the system is in a lower position can cause damage from impact objects in the road. Therefore, conventional height adjustment systems are not suitable for various types of activities. is inefficient.

[0037] Referring to an illustrative example, a truck (e.g., a vehicle) may be configured to lift and lower the truck body. In this embodiment, each wheel has an adjustable suspension system. By increasing or decreasing the compressed air in the movable bellows or movable strut attached to the frame, Thus, the two bellows on the rear wheels can be individually raised or lowered by any desired amount. can be electronically controlled by a central system connected to the air pump or compressor. It's okay to have it.

[0038] According to a first illustrative example corresponding to the tilt mode, the two rear wheels are fitted with bellows. As the air volume decreases, the truck's bed plate drops lower at the rear than at the front. This allows the truck bed plate to be tilted, resulting in the rear rear of the truck A ramp or other device attached to the lift gate lifts the member onto the ramp and off the ramp. For example, a ramp may be placed in a more suitable position or angle for lifting or lowering the The breakover angle of the ramp, which is the angle formed at the point where it intersects with the rack's loading plate, is When loading onto the truck, the motorcycle can be lowered so that it does not hit the bottom. If the truck is not pulled down, the breakover angle may be 45 to 55 degrees. However, if the truck is tilted by lowering the rear, The breakover angle may be only 20 to 30 degrees.

[0039] So in tilt mode, the truck suspension will tilt the front of the truck to 80m m and the rear of the truck is adjusted to be lowered by 70 mm. Of course, the truck may be raised or lowered by other amounts. For example, the suspension may be 5 mm 10mm, 15mm, 20mm, 25mm le, 30mm, 35mm, 40mm, 45mm, 50 mm, 55 mm, 60 mm, 65 mm, 70 mm Torr, 75mm, 80mm, 85mm, 90mm, 9 5mm, 100mm, 125mm, 150mm, 20 The lift may be raised or lowered by 0 mm or more. Depending on the length of the rack, angles of 2, 3, 4, 5 or more degrees can be created. By tilting the truck bed plate by a few degrees, the inclined The platform can be more easily guided by, for example, a motorcycle or all-terrain vehicle. Also, if the distance from the rear of the truck to the ground is reduced, a shorter ramp should be used. may be used to connect from the ground to the truck bed plate.

[0040] In another embodiment, the truck may be set to a "dump mode" and this "dump mode" In "road" all four tires of the truck are lowered so that the truck bed plate is on the ground. approaching (e.g., as close as possible) the truck, resulting in it entering the truck and being removed from the truck bed plate. In a further embodiment, the truck is A horizontal mode may be set, which selects a selected vehicle height and then waits for the vehicle to reach a substantially horizontal position. This involves adjusting the four controllable parts individually so that, among other things, The ability to raise or lower one or more controllable portions in an uneven environment may include:

[0051] 3A-3C, illustrative examples of various suspension modes are shown. The first mode, generally referred to as the dump mode, will now be described with reference to FIG. 3A. In this mode, the suspension controller 116 controls the suspension system 110 In the controllable portion 114, there are four controllable portions 114A, 114B, 114C, 114 We can try to change each of D to the lowest possible value. The value is the "lowest" even if the controllable portion is physically capable of achieving a lower value or position. In this example, four controllable portions 114A, 114B, 114C, 114D, 114E, 114F, 114G, 114H, 114I, 114J, 114K ... 4B, 114C, and 114D are intended to be able to achieve the same height evenly from the contact surface. In an alternative embodiment, the suspension controller 116 may be configured to receive sensor inputs within the vehicle 100. , historical data from previous interactions at that location, or to the suspension controller 116 If it is determined based on the provided knowledge information that the contact surface is not flat, one or more In yet another embodiment, the controller 116 may adjust the controllable portions individually. , the vehicle is displaced during dump mode, or the user displaces the vehicle 100 (e.g., based on the displacement pattern of the specified load (e.g., to balance an unbalanced load). Alternatively, multiple controllable portions may be adjusted individually. In this mode, the controller 116 checks whether the vehicle door is open and damaged before entering the dump mode. You may want to check further to make sure it is not damaged. 116 is in neutral or drive position to prevent the vehicle from being driven in dump mode. The vehicle may be further prevented from being shifted into the drive or reverse positions. It is possible.

[0052] A second mode, generally referred to as the nominal mode, will now be described with reference to FIG. In this mode, the suspension controller 116 controls the suspension system 110. In the controllable portion 114, four controllable portions 115 are configured to drive the vehicle on a standard surface. Change each of 114A, 114B, 114C, and 114D to its default set of values.

In an embodiment, the controller 116 may cause the vehicle to shift or The user may specify that the vehicle 100 should displace (e.g., balance an unbalanced load). One or more controllable portions may further be individually adjusted based on the displacement pattern.

[0053] A third mode, generally referred to as the tilt mode, will now be described with reference to FIG. 3C. In this mode, the suspension controller 116 controls the suspension system 110.

This minimum or maximum value, or the lowest or highest possible value, can be attempted. The highest possible value is the value at which the controllable portion can physically achieve a lower or higher value or position. In an alternative embodiment, the suspension The controller 116 may use sensor inputs within the vehicle 100, history from previous interactions at the location, Based on the data or knowledge provided to the suspension controller 116, If the surface is determined to be non-flat, one or more controllable portions may be individually adjusted. In yet another embodiment, the controller 116 may cause the vehicle to displace during the lean mode. or the user may wish to displace the vehicle 100 (e.g., to balance an unbalanced load). Based on the load displacement pattern specified in the As will be described later, in this tilt mode, the controller 116 Before entering the vehicle, check that the doors are not open or damaged. Similarly, the controller 116 may check whether the vehicle is being operated in a lean mode. To prevent this, the shifter must be in the neutral, drive or reverse position. Furthermore, the controller may further prevent the vehicle from entering the vehicle. raises the rear controllable portions 114C, 114D further upward after load is detected. to prevent the load from accidentally sliding off the vehicle 100 after loading is complete. It can also prevent the device from falling off.

In block 402, the controller The controller 116 obtains user input regarding the suspension mode. The user input regarding the pension is inputted through a graph provided on the vehicle 100 or the mobile device 200. User input can be accessed through the specified suspect Select a suspension mode or correspond to a suspension mode or It may also be specified manually, for example by specifying a predefined action in the session mode (e.g. For example, selecting "Load Items" may be associated with a tilt mode or (The user may specify the desired action via phone input.) Alternatively, the user input may be automatically designated based on profile information or history information by the controller 116 For example, users may receive notifications automatically by posting on social media ( "Move my old recliner" or use the calendar application. When the vehicle 100 stops moving, the mobile device 200 or the vehicle 100 is notified. You can also specify that the vehicle should travel with the cargo loaded to the destination where the pump mode is specified. In some embodiments, no user input may be received, in which case the controller The controller receives only sensor input as described below.

[0055] In block 404, the controller 116 receives the signal from the sensor interface 118 (or One or more sensor inputs are acquired (directly from the vehicle 100). Sensor inputs include speed and acceleration detectors, position sensors (e.g., GPS), cameras, Door ajar sensor, rear door sensor, vehicle occupant detection sensor, and driving status (drive, reverse The vehicle is equipped with a built-in sensor to detect the vehicle's general operation, such as in neutral, park, etc. It may respond to inputs from sensors or interfaces as well as processing functions. These sensors may be used in accordance with exemplary embodiments, such as curb detection sensors, road slope detection devices, etc. The system may further include additional sensors that may not otherwise be available on the vehicle 100. Therefore, the sensor interface 118 may include several additional components or 1 represents an interface for multiple sensors, which may include an interface.

[0056] At block 406, the controller 406 combines the user input and the sensor input. In one embodiment, the suspension mode is determined based on the The decision on the operating mode defaults to the specific mode selected by the user input. This can then be enabled by a sensor input, as described below. In another embodiment, this suspension mode determination is based on sensors such as speed and position. It is also based on matching the input values ​​to a predetermined range of values ​​for each individual suspension mode. These sensor input values ​​are higher than the user input or no user input. When user input and sensor input are received, the controller 11 6 allows for user-selected suspension modes to be selected based on position rather than other selection criteria such as speed. and suspension mode selection, etc. In yet another embodiment, a priority can be associated with the input for the suspension. The decision is made when two or more applicable suspension modes are available and the controller 116 can use sensor input values ​​to select between different suspension modes , may correspond to selection criteria or selection rules. The robot 116 can utilize machine learning techniques, which can analyze user voice ("auto-verbal") "Load the truck" or "Lower the truck"), vehicle status, mobile device applications A wide set of inputs can be used as inputs, such as vehicle speed, location, and occupant identification. The selected suspension mode is generated based on a trained machine learning algorithm. It is possible.

[0057] At decision block 408, the controller 116 enables the selected suspension mode. A test is performed to determine whether the user The user input and the sensor input are used to determine the suspension mode (block 406), and then In one embodiment, the user can activate the selected suspension mode. provides an interface, such as a graphical interface or an auditory interface. You may confirm your suspension mode transition selection by being prompted by The confirmation occurs when the controller 116 initiates the transition without receiving user input and suspending. When the controller 116 is in the selected mode or when the controller 116 is in the This may be necessary if you select a different suspension mode than the one you selected. The controller 116 uses the sensor inputs and rules to determine the selected suspension. As mentioned above, in one embodiment, , where sensor values ​​indicate a velocity above a threshold and position values ​​indicate an obstacle or potential damage. One or more vehicle state indicators indicate the driving mode the vehicle is in (e.g., reverse) that the driver or passenger is in the vehicle 100. If the selected transition to tilt mode or dump mode occurs, Door ajar sensors prevent entry into dump mode. Activation rules may be defaulted, such as geographic suspension mode. Determine the operational limits or preferred speed range (e.g., transition to nominal operating suspension mode) Other validation rules may be set by the user, such as during execution.

[0058] If a transition to a certain suspension mode cannot be enabled, routine 400 will not continue. , information surrounding the failed validation (e.g., a door ajar detected in a user interface) For example, a notification or error regarding the A transition to a certain suspension mode can be enabled or applied. If no valid validation rules exist, then in block 410 the controller 116 Specify the suspension controller settings for the controllable portion 114 of the suspension mode 112. As mentioned above, in one embodiment, the individual components of the controllable suspension system 110 Each controllable portion 114 may be a bellows or strap that can be controlled by adding or removing air. Thus, in this embodiment, the controller 112 controls the air pump or compressor. A signal or signal is generated from a component that can be used to activate the In other embodiments, different types of suspension systems may be used. The device includes a mechanical or electromechanical suspension device having individual controllable portions 114. As noted in the illustrative example, the controller 116 may be configured to adjust the surface to accommodate uneven surface conditions. The individual values ​​of the controllable parts can be adjusted based on the load, imbalance, etc. The adjustment of the controllable portion 114 can be adjusted to accommodate the terrain along the length of the vehicle 100 or the width of a wide vehicle. Additionally, in other examples, individual controllable portions 114 may be configured to In the method used, especially when the tolerance range or tolerance deviation varies over time, The controller 116 creates a profile (e.g., measurement tolerances) for the controllable portion, Based on this profile information, appropriate adjustments can be made to individual commands. do.

[0059] In the first mode, generally referred to as the damp mode, the suspension controller 116 In the controllable portion 114 of the suspension device 110, You can try to change the value to the lowest possible value. In this mode, the controllable 114. In an alternative embodiment, the suspension controller 116 controls the vehicle 100 sensor inputs within the vehicle, historical data from previous interactions at that location, or suspension control If it is determined based on the knowledge information provided to the roller 116 that the contact surface is not flat, In yet another embodiment, one or more controllable portions may be individually adjusted. The rollers 116 are displaced by the vehicle during dump mode or by the user when the vehicle 100 The displacement pattern of the specified load is used to displace it (for example, to balance an unbalanced load). Based on this, one or more controllable portions may be further individually adjusted.

[0060] In a second mode, generally referred to as the nominal mode, the suspension controller 116 , in the controllable portion 114 of the suspension system 110, the value of each of the controllable portions 114 You can try to change it to a default set of values, which are empty. The vehicle 100 may incorporate a characterized optimum position based on aerodynamics, safety, etc. In this example, the controllable portion 114 is evenly spaced from the contact surface. This nominal mode operation is based on the energy consumption and road conditions. The vehicle speed may further be dynamically changed based on the vehicle operating conditions, such as: In this case, the controller 116 may either shift the vehicle during nominal mode or the user may shift the vehicle. Displacement of a specified load to both sides (e.g., to balance an unbalanced load) Based on the pattern, one or more controllable portions may further be individually adjusted.

[0061] In a third mode, generally referred to as a lean mode, the controller 116 In the control device 110, the part of the controllable portion 114 corresponding to the rear of the vehicle is set to a lower value. While the remaining part of the controllable portion 114 corresponding to the front of the vehicle is changed, You can try to raise this minimum or maximum, or even the maximum possible, to a higher value. The lowest possible value or highest possible value is the value at which the controllable part is physically able to reach a lower or higher value. Or even if the position can be achieved, it may correspond to a set threshold. In this state, the suspension controller 116 is configured to receive sensor inputs from the vehicle 100, historical data from previous interactions with the suspension controller 116 or knowledge provided to the suspension controller 116 If the contact surface is determined to be uneven based on the identification information, one or more controllable portions In yet another embodiment, the controller 116 may adjust the tilt mode or the user displaces the vehicle 100 (e.g., due to an imbalance). Based on the specified load displacement pattern, one or more controls are applied to balance the load. The adjustable portions may further be individually adjustable.

[0062] In some embodiments, the controller 116 controls the selected suspension mode. Therefore, additional settings of the vehicle 100 that need to be changed can also be specified. For example, In dump or tilt mode, the vehicle 100 must remain in park driving mode. Therefore, emergency braking may be automatically applied. The vehicle 100 also has different driving modes. (e.g., drive, reverse, neutral) may be prevented. Additionally, in some embodiments, the suspension is raised or lowered using compressed air. However, other systems include electromechanical actuators that control the vehicle height adjacent to the four wheels. It should be understood that other types of devices may also be used.

[0063] In block 412, the controller 116 controls the controllable portion 1 of the suspension system 110. The controller 116 sends settings or commands to make changes to the A command having a value that is converted by the controller 112 or a command by the controllable portion 114 At block 414, the ruler may send a specific command or signal to be used. The 400th race is over.
