[0022] It should be understood that the technical solution of the present application can be applied to the following scenarios, but is not limited to:

[0023] In one embodiment, the embodiment of the present application can be applied to a vehicle height adjustment scenario, for example, it can be applied to a scenario where the vehicle adjusts the height of the main vehicle part and / or the trailer part in real time under different road conditions. Among them, the vehicle can include the vehicle height control system of the present application.

[0024] In addition, the above vehicle may be a new energy vehicle, for example, a new energy commercial vehicle, but is not limited thereto. The vehicle may include a main vehicle part and a trailer part.

[0025] In another embodiment, the embodiment of the present application may be applied to an electronic device including a vehicle height control system, which may be used to simulate the adjustment of the vehicle height when the test vehicle is driving.

[0027] The technical solution of the present application is described below through some embodiments. The following embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0028] Figure 1 A schematic diagram of a vehicle height control system provided in an embodiment of the present application, such as Figure 1 As shown, the vehicle height control system includes: a height control client, a main vehicle height adjustment system and a trailer height adjustment system; wherein:

[0029] A height control client is used to obtain a height control instruction and send the height control instruction to a main vehicle height adjustment system and / or a trailer height adjustment system;

[0030] A main vehicle height adjustment system, for adjusting the height of the main vehicle portion of the target vehicle in response to the height control instruction and according to the main vehicle height adjustment data indicated by the height control instruction; and / or,

[0031] The trailer height adjustment system is used to respond to the height control instruction and adjust the height of the trailer part of the target vehicle according to the trailer height adjustment data indicated by the height control instruction.

[0032] It should be noted that the above-mentioned height control client can be a client based on a web page, a mini-program, an application (Application, APP), etc., and specifically can be a client installed on a mobile phone, a computer, or a vehicle-mounted device. This application does not impose any restrictions on this.

[0033] In addition, the height control client can be a client, used to send height control instructions to the main vehicle height adjustment system and / or the trailer height adjustment system; or, it can also be two different clients, used to send height control instructions to the main vehicle height adjustment system and the trailer height adjustment system respectively.

[0034] Similarly, altitude control instructions can also include two forms:

[0035] In the first form, the height control instruction is two instructions, namely, the main vehicle height control instruction and the trailer height control instruction, which respectively indicate the main vehicle height adjustment data and the trailer height adjustment data. Accordingly, the height control client is used to send the main vehicle height control instruction to the main vehicle height adjustment system, and the main vehicle height adjustment system is used to respond to the main vehicle height control instruction and adjust the height of the main vehicle part of the target vehicle; and / or, the height control client is used to send the trailer height control instruction to the trailer height adjustment system, and the trailer height adjustment system is used to respond to the trailer height control instruction and adjust the height of the trailer part of the target vehicle.

[0036] In the second form, the height control instruction is an instruction including a main vehicle height control instruction and / or a trailer height control instruction, which respectively indicate the main vehicle height adjustment data and the trailer height adjustment data. Correspondingly, if the height of the main vehicle part needs to be adjusted, the height control instruction is the main vehicle height control instruction, and the height control client is used to send the main vehicle height control instruction to the main vehicle height adjustment system, and the main vehicle height adjustment system is used to respond to the main vehicle height control instruction and adjust the height of the main vehicle part in the target vehicle; if the height of the trailer part needs to be adjusted, the height control instruction is the trailer height control instruction, and the height control client is used to send the trailer height control instruction to the trailer height adjustment system, and the trailer height adjustment system is used to respond to the trailer height control instruction and adjust the height of the trailer part in the target vehicle; if the height of the main vehicle part and the trailer part needs to be adjusted at the same time, the height control instruction is an instruction including the main vehicle height control instruction and the trailer height control instruction, and the height control client is used to send the height control instruction to the main vehicle height adjustment system and the trailer height adjustment system respectively, the main vehicle height adjustment system is used to respond to the main vehicle height control instruction in the height control instruction, and adjust the height of the main vehicle part in the target vehicle, and the trailer height adjustment system is used to respond to the trailer height control instruction in the height control instruction and adjust the height of the trailer part in the target vehicle.

[0037] In one embodiment, the height control instruction may include the main vehicle height adjustment data and / or the trailer height adjustment data. The main vehicle height adjustment data may be a height value that is increased or decreased according to the needs of the main vehicle part, or a height value after the main vehicle part is adjusted; similarly, the trailer height adjustment data may be a height value that is increased or decreased according to the needs of the trailer part, or a height value after the trailer part is adjusted.

[0038] The following introduces the communication methods between the main vehicle height adjustment system and the trailer height adjustment system and the height control client:

[0039] In one embodiment, the height control client may be connected to the main vehicle height adjustment system and the trailer height adjustment system respectively by wired connection.

[0040] Specifically, communication can be performed through physical media such as Ethernet cables and optical fibers, which can achieve stable and high-speed data transmission.

[0041] In another embodiment, the height control client may be connected to the main vehicle height adjustment system and the trailer height adjustment system respectively by wireless connection.

[0042] Specifically, the main vehicle height adjustment system includes a main vehicle wireless module, and the trailer height adjustment system includes a trailer wireless module; the main vehicle wireless module is used to wirelessly connect to the height control client and receive height control instructions sent by the height control client; the trailer wireless module is used to wirelessly connect to the height control client and receive height control instructions sent by the height control client.

[0043] For example, the main vehicle wireless module includes the main vehicle Bluetooth module, and the trailer wireless module includes the trailer Bluetooth module; the main vehicle Bluetooth module is used to communicate with the height control client based on Bluetooth and receive the height control instructions sent by the height control client; the trailer Bluetooth module is used to communicate with the height control client based on Bluetooth and receive the height control instructions sent by the height control client.

[0044] That is to say, the height control client can communicate with the main vehicle height adjustment system and the trailer height adjustment system through Bluetooth. Among them, Bluetooth is a short-range wireless communication technology that can simplify the connection and data transmission between devices and realize real-time and efficient command transmission.

[0045] For another example, the main vehicle wireless module includes the main vehicle wireless network module, and the trailer wireless module includes the trailer wireless network module; the main vehicle wireless network module is used to communicate with the height control client based on the wireless network (), and receive the height control instructions sent by the height control client; the trailer wireless network module is used to communicate with the height control client based on the wireless network, and receive the height control instructions sent by the height control client.

[0046] Among them, wireless network refers to the network technology that uses electromagnetic waves as the transmission medium to achieve wireless communication between devices. Wi-Fi network is a common wireless network.

[0047] The following is an introduction to the height adjustment process of the main vehicle height adjustment system and the trailer height adjustment system for the corresponding parts of the vehicle:

[0048] In one embodiment, the main vehicle height adjustment system includes: a main vehicle controller, at least one main vehicle solenoid valve, at least one main vehicle airbag corresponding to the at least one main vehicle solenoid valve, at least one main vehicle air reservoir and at least one main vehicle height sensor; at least one main vehicle height sensor is used to collect the height of the main vehicle part from the ground and send the height of the main vehicle part from the ground to the main vehicle controller; the main vehicle controller is used to perform corresponding on-off control of at least one main vehicle solenoid valve according to the height of the main vehicle part from the ground and the main vehicle height adjustment data; at least one main vehicle solenoid valve is used to correspondingly control the gas flow between at least one main vehicle airbag and at least one main vehicle air reservoir to adjust the height of the main vehicle part;

[0049] Correspondingly, the trailer height adjustment system includes: a trailer controller, at least one trailer solenoid valve, at least one trailer airbag corresponding to the at least one trailer solenoid valve, at least one trailer air tank and at least one trailer height sensor; at least one trailer height sensor is used to collect the height of the trailer part from the ground and send the height of the trailer part from the ground to the trailer controller; the trailer controller is used to perform corresponding on-off control of the at least one trailer solenoid valve according to the height of the trailer part from the ground and the trailer height adjustment data; at least one trailer solenoid valve is used to correspondingly control the gas flow between at least one trailer airbag and at least one trailer air tank to adjust the height of the trailer part.

[0050] The main vehicle controller and the trailer controller may both be controllers based on an electronic control unit in an electronic controlled air suspension system (ECAS).

[0051] For example, Figure 2 As shown, taking the main vehicle part of the target vehicle as an example, the power battery is integrated in the chassis of the main vehicle and is at a relatively low height. When encountering a road with obstacles, it is easy to be touched. In combination with the technical solution of the present application, the main vehicle part may include a main vehicle height adjustment system, and a height control instruction may be sent to the main vehicle height adjustment system through the main vehicle remote controller 1 (i.e., the height control client). The main vehicle height adjustment system may adjust the height of the main vehicle part in real time according to the main vehicle height adjustment instruction, thereby controlling the lifting and lowering of the chassis outside the vehicle, achieving visual adjustment of the vehicle height, and avoiding operational restrictions caused by the position of the remote controller, i.e., the position of the client, to achieve real-time and flexible vehicle height adjustment.

[0052] The main vehicle height adjustment system includes: a main vehicle controller, airbag 1, airbag 2, solenoid valve 1, solenoid valve 2, height sensor 1, height sensor 2, main vehicle air reservoir, and main vehicle Bluetooth module. Height sensor 1 is used to collect the height H1 from the ground and send it to the main vehicle controller; height sensor 2 is used to collect the height H2 from the ground and send it to the main vehicle controller; the main vehicle Bluetooth module is used to establish a connection with a mobile phone installed with a height client through Bluetooth, and can send height control instructions to the main vehicle controller through the interface of the height client (this application will introduce this in subsequent embodiments); the main vehicle controller is used to control the on and off of solenoid valves 1 and 2, and then control the ventilation volume of airbags 1 and 2 through the main vehicle air reservoir to achieve the adjustment of the main vehicle chassis suspension height Ha.

[0053] Exemplary, combined Figure 2 ,like Figure 3 As shown, the trailer height adjustment system includes: a trailer controller, an airbag 3, an airbag 4, a solenoid valve 3, a solenoid valve 4, a height sensor 3, a height sensor 4, a trailer air cylinder, and a trailer Bluetooth module. The height sensor 3 is used to collect the height H3 from the ground and send it to the trailer controller; the height sensor 4 is used to collect the height H4 from the ground and send it to the trailer controller; the trailer Bluetooth module is used to establish a connection with a mobile phone installed with a height client through Bluetooth, and can send a height control instruction to the trailer controller through the interface of the height client (this application will introduce this in subsequent embodiments); the trailer controller controls the on and off of the solenoid valve 1 and the solenoid valve 2, and then controls the ventilation volume of the airbag 3 and the airbag 4 through the trailer air cylinder to adjust the trailer chassis suspension height Hb.

[0054] like Figure 3 As shown in (a) in the figure, if only the main vehicle part is equipped with a height adjustment system, that is, the target vehicle includes the main vehicle height adjustment system but not the trailer height adjustment system, and only the main vehicle height can be adjusted, then when the main vehicle is lifted or lowered, the trailer posture will be passively adjusted with the main vehicle posture, which will cause the trailer driving posture to change, and the passability under different road conditions will deteriorate; at the same time, the trailer cargo box posture will also be affected, the cargo position will change with the cargo box posture, and the cargo box levelness is poor, which is not conducive to the stability of driving and transporting goods.

[0055] like Figure 3As shown in (b), if both the main vehicle and the trailer are equipped with a height adjustment system, that is, the target vehicle includes a main vehicle height adjustment system and a trailer height adjustment system, the posture of the main vehicle and the trailer can be adjusted to achieve a coordinated height adjustment effect between the main vehicle and the trailer, and the cargo box has a good levelness, ensuring the stability of driving and transporting goods. On this basis, the height control client can be moved through Bluetooth and the height control client to achieve height adjustment of the main vehicle and the trailer anytime and anywhere.

[0056] In the above content, through the main vehicle height adjustment system, the trailer height adjustment system and the height control client wirelessly connected thereto, it is possible to send height control instructions anytime and anywhere through terminal devices such as mobile phones installed with the height control client, thereby achieving real-time, coordinated, continuous and dynamic adjustment of the main vehicle and trailer, improving the control convenience of vehicle height adjustment, and not being restricted by the operating space of the wired control handle, so as to obtain vehicle passability and a smooth driving experience under different road conditions.

[0057] The vehicle height control method involved in this application is introduced below:

[0058] It should be noted that the embodiment of the vehicle height control method is similar to the embodiment of the above-mentioned vehicle height control system, and their corresponding contents and effects can be referenced to each other, and this application will not repeat them here.

[0059] Figure 4 A flow chart of a vehicle height control method provided in an embodiment of the present application, the method is applied to a vehicle height control system including a height control client, a main vehicle height adjustment system and a trailer height adjustment system, such as Figure 4 As shown, the method may include the following steps:

[0060] S410: The height control client obtains a height control instruction, and sends the height control instruction to the main vehicle height adjustment system and / or the trailer height adjustment system;

[0061] S420: the main vehicle height adjustment system responds to the height control instruction and adjusts the height of the main vehicle part of the target vehicle according to the main vehicle height adjustment data indicated by the height control instruction;

[0062] S430: The trailer height adjustment system responds to the height control instruction and adjusts the height of the trailer part of the target vehicle according to the trailer height adjustment data indicated by the height control instruction.

[0063] Among them, S420 and S430 can be executed simultaneously, or one of them can be executed selectively according to the content indicated by the altitude control instruction.

[0064] In one embodiment, the main vehicle height adjustment system includes a main vehicle wireless module, and the trailer height adjustment system includes a trailer wireless module; the main vehicle wireless module is wirelessly connected to the height control client to receive height control instructions sent by the height control client; the trailer wireless module is wirelessly connected to the height control client to receive height control instructions sent by the height control client.

[0065] In one embodiment, the main vehicle wireless module includes a main vehicle Bluetooth module, and the trailer wireless module includes a trailer Bluetooth module; the main vehicle Bluetooth module communicates with the height control client based on Bluetooth, and receives the height control instructions sent by the height control client; the trailer Bluetooth module communicates with the height control client based on Bluetooth, and receives the height control instructions sent by the height control client.

[0066] Figure 5 A flowchart of another vehicle height control method provided in an embodiment of the present application, the method is applied to a height control client, such as Figure 5 As shown, the method may include the following steps:

[0067] S510: Displaying a height adjustment page;

[0068] S520: Obtain a trigger operation for a height adjustment indicator in a height adjustment page;

[0069] S530: In response to a trigger operation on the altitude adjustment mark, determining an altitude control instruction;

[0070] S540: Send the height control instruction to the main vehicle height adjustment system and / or the trailer height adjustment system accordingly, so that the main vehicle height adjustment system responds to the height control instruction and adjusts the height of the main vehicle part of the target vehicle according to the main vehicle height adjustment data indicated by the height control instruction; and / or, so that the trailer height adjustment system responds to the height control instruction and adjusts the height of the trailer part of the target vehicle according to the trailer height adjustment data indicated by the height control instruction.

[0071] It should be noted that the height adjustment page can be a page used to send height control instructions to the main vehicle height adjustment system and / or the trailer height adjustment system; or, it can also be two different pages, used to send height control instructions to the main vehicle height adjustment system and the trailer height adjustment system respectively.

[0072] The following is an example of a height adjustment page including a main vehicle height adjustment page and a trailer height adjustment page, where the main vehicle height adjustment page and the trailer height adjustment page can be different pages located in the same display interface, or can be pages located in different display interfaces, and this application does not limit this.

[0073] In one embodiment, the height adjustment page includes: a main vehicle height adjustment page and a trailer height adjustment page; the height adjustment mark includes: a height increase or decrease mark and / or a height input box; accordingly, the main vehicle height adjustment page includes: the main vehicle height increase or decrease mark in the height increase or decrease mark and / or the main vehicle height input box in the height input box; the trailer height adjustment page includes: the trailer height increase or decrease mark in the height increase or decrease mark and / or the trailer height input box in the height input box.

[0074] Correspondingly, the above-mentioned acquisition of the trigger operation for the height adjustment mark in the height adjustment page includes: obtaining the trigger operation for the main vehicle height increase or decrease mark in the main vehicle height adjustment page, or the data input or selection operation for the main vehicle height input box, and / or, obtaining the trigger operation for the trailer height increase or decrease mark in the trailer height adjustment page, or the data input or selection operation for the trailer height input box.

[0075] Among them, the trigger operations, selection operations and other operations involved in this application can specifically be single-clicking, double-clicking, pressing, dragging to a designated area or floating touch gestures, etc., and this application does not impose any restrictions on this.

[0076] For example, Figure 6 As shown, the main vehicle height increase / decrease mark may include a main vehicle height increase mark and a main vehicle height decrease mark, respectively as shown in Figure 6 The height adjustment page of the main vehicle is shown as a circle with an upward arrow and a circle with a downward arrow. The trailer height increase and decrease mark can include a trailer height increase mark and a trailer height decrease mark, as shown in Figure 1. Figure 6 The mid-trailer height adjustment page is indicated by a circle containing an upward arrow and a circle containing a downward arrow.

[0077] For example, a trigger operation on the height adjustment mark may correspond to a main vehicle height adjustment data and / or trailer height adjustment data. For example, if a user clicks on the main vehicle height increase mark, the main vehicle height adjustment data may be determined as: increasing the main vehicle height by 2 cm.

[0078] Alternatively, a trigger operation for the height adjustment mark may cause the height of the corresponding main vehicle part or trailer part to increase or decrease continuously until a trigger operation for the stop button is obtained (this will be described in the subsequent embodiments), or until the height of the corresponding main vehicle part and / or trailer part increases or decreases to a specific value. Accordingly, in this case, the height adjustment data may be: controlling the main vehicle height to increase or decrease continuously, and / or controlling the trailer height to increase or decrease continuously.

[0079] In one embodiment, the height adjustment page further includes: a leveling button, and the vehicle height control method further includes the following steps:

[0080] Acquire a trigger operation for a leveling button; in response to the trigger operation for the leveling button, send a leveling control instruction to the main vehicle height adjustment system and / or the trailer height adjustment system, so that the main vehicle height adjustment system and / or the trailer height adjustment system respond to the leveling control instruction and control the height correspondence between the main vehicle part and the trailer part.

[0081] For example, Figure 6 As shown, both the main vehicle height adjustment page and the trailer height adjustment page may include leveling buttons, respectively, as shown in FIG. Figure 6 For example, in response to the user's triggering operation of the leveling button on the main vehicle height adjustment page, the height of the main vehicle part can be controlled to be the height of the trailer part; in response to the user's triggering operation of the leveling button on the trailer height adjustment page, the height of the trailer part can be controlled to be the height of the main vehicle part.

[0082] In one embodiment, the height adjustment page further includes: a stop button, and the vehicle height control method further includes the following steps:

[0083] Obtain a trigger operation for a stop button; in response to the trigger operation for the stop button, send a stop control instruction to the main vehicle height adjustment system and / or the trailer height adjustment system, so that the main vehicle height adjustment system and / or the trailer height adjustment system responds to the stop control instruction and stops adjusting the height of the main vehicle part and / or the trailer part.

[0084] For example, Figure 6 As shown, both the main vehicle height adjustment page and the trailer height adjustment page may include a stop button, respectively, as shown in FIG. Figure 6 For example, in response to the user's triggering operation of the stop button on the main vehicle height adjustment page, the height adjustment of the main vehicle part can be stopped; in response to the user's triggering operation of the stop button on the trailer height adjustment page, the height adjustment of the trailer part can be stopped.

[0085] In the above content, a movable operation control interface is provided, which can ensure the consistency of the height adjustment posture of the main vehicle and the trailer in a visual way, ensure the stability of the cargo box, and prevent the cargo from bumping.
