[0001] This invention relates to the field of vehicle technology, and more specifically to a vehicle body height control method, device, equipment, and computer-readable storage medium. Background Technology

[0002] With the rapid popularization of the new energy vehicle industry, air suspension systems, with their ability to dynamically adjust vehicle height and suspension stiffness, have been widely used in new energy vehicles to improve ride comfort, handling stability, and passability on complex road conditions. Air suspension systems typically use an onboard controller to collect basic parameters such as vehicle speed, throttle opening, and braking signals, and control the inflation and deflation of the air springs in the air suspension system according to preset fixed-level rules, thereby achieving several levels of vehicle height adjustment.

[0003] However, existing air suspension systems are mainly used for vehicle height adjustment during driving. When users need to open the trunk or front trunk to retrieve or place items, the vehicle chassis is too high, which is inconvenient for users, especially children and the elderly, and there is a risk of items falling when they are heavy. Summary of the Invention

Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] like Figure 1 As shown in the figure, an embodiment of the present invention discloses a vehicle body height control method, including the following steps: Step S10: Obtain the door opening / closing signal of the vehicle storage compartment, vehicle status information, and environmental information; Step S20: Determine whether the execution conditions for vehicle height adjustment are met based on the vehicle status information and the environmental information. Step S30: If yes, then determine whether the door of the vehicle storage compartment is open or whether the door of the vehicle storage compartment changes from open to closed based on the opening and closing signal of the vehicle storage compartment door. In step S40, if a vehicle storage compartment door is opened, the air suspension corresponding to the opened vehicle storage compartment door is controlled to descend; if a vehicle storage compartment door changes from open to closed, the air suspension corresponding to the changed vehicle storage compartment door is controlled to ascend.

[0019] The opening and closing signals of the vehicle's storage compartment doors are obtained by real-time monitoring of the opening and closing signals of the front trunk door and the rear trunk door using door status sensors.

[0020] Vehicle status information includes: vehicle speed, gear, READY status, power mode, and battery charge. READY status refers to the new energy (pure electric / hybrid) vehicle's high-voltage system completing self-checks, contactor closure, and power output channel establishment, placing the vehicle in an activated standby mode ready for immediate driving. Power mode refers to the distribution logic and control level of battery power by the vehicle's low-voltage electrical system under different operating conditions.

[0021] Environmental information includes: the slope of the road where the vehicle is located, the outdoor temperature, and the weather conditions.

[0022] Furthermore, the acquired door opening and closing signals, vehicle status information, and environmental information are all time-stamped to align the multiple acquired signals in time.

[0023] The conditions for vehicle height adjustment are: vehicle speed is 0 and in non-maintenance mode, road slope is less than or equal to 15° and battery charge is greater than or equal to 15%.

[0024] If the above conditions for adjusting the vehicle height are met, the air suspension height can be adjusted to raise or lower the vehicle. If the above conditions for adjusting the vehicle height are not met, it means that adjusting the air suspension is risky due to the vehicle's own condition and the external environment, and therefore cannot be used.

[0025] In addition to meeting the conditions for vehicle height adjustment, it's also necessary to determine if there's a need for air suspension height. When the opening / closing signal of the vehicle's storage compartment door is detected, it indicates that the user needs to retrieve or place items from the storage compartment. In this case, the air suspension corresponding to the open storage compartment door can be lowered to facilitate the user's access. When the opening / closing signal of the vehicle's storage compartment door is detected, it indicates that the user has completed retrieving or placing items from the storage compartment. In this case, the air suspension corresponding to the closed storage compartment door can be raised to meet the air suspension height requirements for following vehicles. If no opening or closing signal of the storage compartment door is detected, it means that the user does not need to use the storage compartment, and the air suspension does not need to perform any action.

[0026] Furthermore, the present invention does not require a specific order for determining whether the execution conditions for vehicle height adjustment are met, or for determining whether the door of the vehicle storage compartment is open or closed. As long as both the execution conditions for determining whether vehicle height adjustment is met and the determination whether the door of the vehicle storage compartment is open or closed are met, the invention is considered to be within the scope of protection of the present invention.

[0027] Furthermore, the controlled descent height of the air suspension varies depending on the vehicle model. In one embodiment, the descent height for SUVs is between 50mm and 60mm, with a descent time of 15 seconds; for sedans or MPVs, it is between 30mm and 40mm, with a descent time of 10 seconds. Of course, the above descent height and time are merely one embodiment, and this invention does not limit the descent height and time.

[0028] Furthermore, the opening and closing signals of the vehicle's storage compartment can be signals for the opening or closing of the power tailgate and power front doors, as well as signals for the opening or closing of the foot-activated tailgate and foot-activated front doors.

[0029] This invention acquires the opening and closing signals of the vehicle's storage compartment door, controls the air suspension corresponding to the door to descend when the door is open, and controls the air suspension corresponding to the door to rise when the door changes from open to closed. This allows for timely adjustment of the air suspension height, providing convenience for users to retrieve and place items in the vehicle's storage compartment and preventing items from falling.

[0030] like Figure 2 As shown, in one embodiment, if a vehicle storage compartment door is opened, controlling the air suspension corresponding to the opened vehicle storage compartment door to descend includes the following steps: Step S41: Determine whether the door of another vehicle's storage compartment is open at the same time; Step S42, if yes, then control the currently descending air suspension to stop descending, control the air suspension corresponding to the door of the other vehicle storage compartment to descend to the first preset height, and then control the stopped air suspension to descend to the first preset height; Step S43: If not, control the currently descending air suspension to descend to the first preset height.

[0031] Considering that users might open another vehicle storage compartment door while the air suspension is lowering, a multi-door queue scheduling mechanism is activated when multiple storage compartment doors open sequentially. The air suspension corresponding to the last opened storage compartment door receives the highest priority and begins its descent first, interrupting the currently descent process. The descent of the air suspension corresponding to the last opened storage compartment door resumes only after the latter has completed. This mechanism ensures that the most recently opened storage compartment door always responds when users are retrieving or placing items in multiple locations, avoiding user waiting. Once the air suspension corresponding to the most recently opened storage compartment door has descended, it remains in a descent state until the door closes, at which point the corresponding air suspension is raised, ensuring uninterrupted and convenient access for users while the door remains open.

[0032] In one embodiment, when the conditions for vehicle height adjustment are met and the opening of the front trunk door is detected, the front air suspension corresponding to the front trunk door is controlled to descend. If, during the descent of the front air suspension, the opening of the rear trunk door is detected, the descent of the front air suspension corresponding to the front trunk door is stopped, and the descent of the rear air suspension corresponding to the rear trunk door is controlled until the rear air suspension reaches a first preset height. Then, the descent of the front air suspension corresponding to the front trunk door continues to the first preset height. Once the air suspensions corresponding to the front and rear trunk doors have descended to the first preset height, they remain at that height until a door changes from open to closed, at which point the air suspension corresponding to that door is controlled to rise.

[0033] This invention, by setting up a multi-queue scheduling mechanism, can always prioritize responding to the user's latest item retrieval and placement needs.

[0034] In one embodiment, after the air suspension is lowered to a first preset height, the method further includes the following steps: adjusting the height of the air suspension corresponding to the vehicle storage compartment according to the weight of the cargo loaded in the vehicle storage compartment, so that the air suspension is maintained at the first preset height.

[0035] Once the air suspension descends to the first preset height, taking or placing items in the vehicle's storage compartment will change the air suspension load corresponding to that storage compartment.

[0036] Specifically, when placing items in the vehicle's storage compartment, the increased weight of the items directly leads to an increased load on the corresponding air suspension, which will gradually lower the air suspension under the influence of gravity; conversely, when retrieving items, the decreased weight of the items in the vehicle's storage compartment directly leads to a decreased load on the corresponding air suspension, which will cause the air suspension to rise.

[0037] To ensure that the air suspension corresponding to the vehicle's storage compartment for retrieving and placing items is always stably maintained at a first preset height, this invention introduces an adaptive compensation control mechanism based on load changes.

[0038] When retrieving or placing items, if an increase in the weight of items in the vehicle's storage compartment is detected, the corresponding air suspension will inflate, increasing the air pressure inside the airbag to enhance support and effectively counteract the downward pressure effect caused by the increased load. Conversely, if a decrease in the weight of items in the storage compartment is detected, the corresponding air suspension will deflate, appropriately reducing the air pressure inside the airbag to decrease support. In this way, by constantly sensing changes in the weight of items in the storage compartment and dynamically adjusting the air pressure of the air suspension system, the vehicle body maintains a constant height when retrieving or placing items.

[0039] In one embodiment, a user's height setting instruction is received, and the first preset height is determined based on the height setting instruction.

[0040] Users can also customize the height at which the air suspension lowers when retrieving or placing items in the vehicle's storage compartment, based on their own height and habits. In other words, the first preset height can be customized according to user preferences.

[0041] like Figure 3 As shown, in one embodiment, if a vehicle storage compartment door is opened, after controlling the air suspension corresponding to the opened vehicle storage compartment door to descend, the following steps are included: Step S50: Determine whether the door of the vehicle's storage compartment corresponding to the air suspension that is lowering is closed; Step S60: If yes, control the air suspension to stop descending and rise to the second preset height.

[0042] When users are retrieving or placing items, they may accidentally open the vehicle's storage compartment door. If, during the descent of the air suspension corresponding to an open storage compartment door, the air suspension detects that the door is closed, it immediately stops descending and raises to a second preset height. Furthermore, the second preset height is the air suspension height during normal vehicle operation.

[0043] In one embodiment, after controlling the air suspension corresponding to the opened vehicle storage compartment door to descend if the compartment door is opened, the method further includes the following steps: determining whether the vehicle has triggered a safety protection mechanism; if so, controlling the air suspension to stop descending.

[0044] During the descent of the air suspension, unexpected events may occur. To ensure vehicle safety, this invention introduces a safety protection mechanism. When the vehicle triggers the safety protection mechanism, it indicates that continuing the descent of the air suspension poses a safety risk, and the air suspension is then controlled to stop descending. Furthermore, after the air suspension stops descending, it can be controlled to rise to a second preset height to further ensure vehicle safety.

[0045] Security protection mechanisms include: 1. Road slope changes: When the slope is greater than 15°, the air suspension will stop descending. After stopping the descent, the air suspension can be raised to a second preset height. Furthermore, when the slope is greater than or equal to 5° and less than or equal to 15°, the descent speed of the air suspension will be reduced to improve vehicle safety during air suspension adjustment.

[0046] 2. Automatic Collision Avoidance with Rebound: During the descent of the air suspension, if an obstacle is detected below, the air suspension will stop descending. To allow for easy access to items in the vehicle's storage compartment, the air suspension will rebound 10-20mm after detecting an obstacle and maintain that height. Although the air suspension does not descend to the first preset height when an obstacle is present, it still descends partially to allow the user to access items in the storage compartment. Furthermore, the air suspension can be raised to a second preset height to prevent collisions with the vehicle body.

[0047] 3. Side door collision prevention: There is a risk of collision if a side door opens during the air suspension's descent. Upon detecting an open side door, the air suspension should stop descent. After stopping, the air suspension can be raised to a second preset height. Furthermore, when the air suspension corresponding to the front trunk is descenting, since the air suspension corresponding to the rear trunk is not descenting, a collision risk only exists when the front side door is opened. This can be configured so that when the air suspension corresponding to the current trunk is descenting, if the front side door is opened, the air suspension stops descent and rises to the second preset height; similarly, when the air suspension corresponding to the rear trunk is descenting, if the rear side door is opened, the air suspension stops descent and rises to the second preset height.

[0048] 4. Height Limit Protection: When the height limit protection is triggered, the air suspension will stop descending and remain in that position. Alternatively, the air suspension can stop descending and rise to a second preset height. After stopping the descent, the air suspension can also be raised to the second preset height.

[0049] 5. In-driving protection: During the descent of the air suspension, the user may be driving the vehicle. To prevent collisions caused by the air suspension, the air suspension will stop descent if the vehicle speed is not zero. After stopping the descent, the air suspension can be raised to a second preset height.

[0050] 6. Dynamic recovery upon start-up: When the READY state is detected, the air suspension is controlled to stop descending. After the air suspension stops descending, it can also be controlled to rise to a second preset height.

[0051] 7. Air pump overheat protection: When the air pump temperature of the air suspension is greater than or equal to 120℃, the air suspension will stop descending and remain in that position.

[0052] 8. User-controlled air suspension descent can be stopped via physical buttons or the central control screen.

[0053] 9. Lifting / Maintenance Mode Interlock.

[0054] 10. A system malfunction has been detected.

[0055] Furthermore, considering the impact of weather on the air suspension, when heavy rain is detected, the descent speed of the air suspension is reduced to 50% of the normal descent speed to prioritize the response speed of the air suspension when it rebounds; when icy or snowy weather is detected and the temperature is less than or equal to -10°C, the descent action of the air suspension is restricted to prevent the air suspension from freezing and being damaged.

[0056] This invention protects the vehicle body by setting up a safety protection mechanism during the adjustment of the air suspension height.

[0057] In one embodiment, the step of determining whether the execution conditions for vehicle height adjustment are met based on the vehicle status information and the environmental information further includes the following steps: obtaining the vehicle speed, vehicle mode, battery level, and road slope from the vehicle status information and the environmental information; and determining whether the execution conditions for vehicle height adjustment are met based on the vehicle speed, vehicle mode, battery level, and road slope.

The second judgment unit is used to determine, if yes, whether the door of the vehicle storage compartment is open or whether the door of the vehicle storage compartment changes from open to closed based on the door opening and closing signal of the vehicle storage compartment. An actuator is configured to, if a vehicle storage compartment door is opened, control the air suspension corresponding to the opened vehicle storage compartment door to descend; and if a vehicle storage compartment door changes from open to closed, control the air suspension corresponding to the closed vehicle storage compartment door to ascend.
