[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0031] Figure 1 Schematic diagram of the implementation scenario provided by the embodiment of the present application. Figure 1 The implementation scenario provided by the embodiment of the present application includes a tire pressure adjustment unit 11 located at the wheel end of the vehicle and an on-board control unit 12.

[0032] The tire pressure regulating unit 11 is located at the wheel end of the vehicle and can be used to collect tire pressure data at the wheel end. The vehicle-mounted control unit 12 can be connected to the tire pressure regulating unit 11 in a wired or wireless manner to control the tire pressure regulating unit 11 to regulate the tire pressure at the wheel end.

[0033] Optionally, the vehicle-mounted control unit 12 may be a controller, a control system, or a server, a server cluster, etc., and this application does not impose any limitation on this.

[0034] Those skilled in the art should understand that the above-mentioned tire pressure adjustment unit 11 and the vehicle-mounted control unit 12 are only examples, and other existing or future tire pressure adjustment units and computer electronic devices, if applicable to the present application, should also be included in the scope of protection of the present application and are included here by reference.

[0035] Figure 2 is a schematic diagram of the structure of a system for adjusting vehicle tire pressure provided in an embodiment of the present application. Figure 2 The system for adjusting vehicle tire pressure provided in an embodiment of the present application may include a tire pressure adjustment unit 210 and a control unit 220.

[0036] The tire pressure adjustment unit 210 located at the wheel end of the vehicle is configured to collect tire pressure data at the wheel end; and adjust the tire pressure at the wheel end according to the adjustment signal of the control unit 220.

[0037] Schematically, a vehicle may include a wheel end and a non-wheel end. The wheel end may be, for example, a related component that can maintain the same motion state as the wheel during driving and the wheel of the vehicle, and the non-wheel end may be, for example, a related component that cannot maintain the same motion state as the wheel during driving. The tire pressure adjustment unit 210 located at the wheel end may maintain the same motion state as the wheel, and thus may collect tire pressure data and adjust tire pressure for the wheel end in driving state or non-driving state.

[0038] In some examples, the tire pressure regulating unit 210 may include, for example, an air pressure detection device and an air pressure regulating device, and the tire pressure regulating unit may be in communication with the control unit 220. The air pressure detection device may be used to collect tire pressure data at the wheel end, and send the collected tire pressure data to the control unit 220. The air pressure detection device may include, for example, an air pressure sensor, which may collect tire pressure data at the wheel end according to the air pressure change inside the wheel at the wheel end, and convert the collected tire pressure data into an electrical signal and send it to the control unit 220. The air pressure regulating device may be used to adjust the tire pressure at the wheel end according to the adjustment signal sent by the control unit 220. The air pressure regulating device may include, for example, an air pump, an electromagnetic air valve, etc., which may inflate or deflate the wheel at the wheel end under the control of the adjustment signal sent by the control unit 220.

[0039] Considering that when the vehicle is in motion, the non-wheel end of the vehicle cannot maintain the same motion state as the wheel end, and thus the power source at the non-wheel end of the vehicle cannot supply power to the wheel end through wired power supply. In view of this, the embodiment of the present application provides a system for regulating the tire pressure of a vehicle, which can provide power supply to the wheel end of the vehicle through wireless power supply to ensure the stability and reliability of the operation of the wheel end equipment (such as the tire pressure adjustment unit 210).

[0040] In some embodiments, the system for adjusting the tire pressure of a vehicle provided in the embodiments of the present application may further include a wireless charging unit. The wireless charging unit may include, for example, a transmitter and a receiver. The transmitter may be connected to a power source at a non-wheel end of the vehicle, for example, to convert the electric energy of the power source at the non-wheel end into an electromagnetic signal for transmission; the receiver is located at the wheel end of the vehicle, for receiving the electromagnetic signal transmitted by the transmitter and converting the electromagnetic signal transmitted by the transmitter into electric energy to supply power to the wheel end. The transmitter and the receiver may be, for example, electromagnetic induction coils, and the power transmission between the transmitter and the receiver may be, for example, based on the electromagnetic induction phenomenon.

[0041] Considering that when the vehicle is in motion, the wireless charging unit may be disturbed, resulting in the interruption of the power supply to the wheel end. In view of this, in order to further improve the stability of the system for adjusting the tire pressure of the vehicle, especially the stability of the equipment at the wheel end, a battery can be set at the wheel end of the vehicle to ensure the stability of the power supply to the wheel end.

[0042] In some embodiments, the system for regulating vehicle tire pressure provided in the present application may also include a battery located at the wheel end. The battery may, for example, be connected to the tire pressure regulating unit 210 and the receiving end of the wireless charging unit. The battery may, for example, include a charging mode and a discharging mode. The charging mode may be used to store the electrical energy provided by the receiving end of the wireless charging unit according to the control of the control unit 220, and the discharging mode may be used to supply power to the tire pressure regulating unit 210 according to the control of the control unit 220.

[0043] In some embodiments, the system for adjusting the tire pressure of the vehicle may include both a wireless charging unit and a battery at the wheel end, that is, the vehicle may simultaneously supply power to the wheel end through the wireless charging unit and the battery at the wheel end. At this time, the principle of the wireless charging unit and the battery supplying power to the wheel end may refer to the following standard, for example: the battery is preferentially used to supply power to the wheel end.

[0044] In some embodiments, the method in which the control unit 220 controls the charging mode of the battery at the wheel end to store the electric energy provided by the receiving end of the wireless charging unit may include, for example: when the electric power of the battery at the wheel end is lower than the first electric power threshold, the control unit 220 controls the wireless charging unit to work so that the battery at the wheel end can store the electric energy provided by the receiving end of the wireless charging unit through the charging mode. The value of the first electric power threshold may be adjusted according to the actual application situation, and this application does not impose any restrictions on this.

[0045] In some embodiments, the method in which the control unit 220 controls the discharge mode of the battery at the wheel end to supply power to the tire pressure regulating unit 210 may include, for example: when the power level of the battery at the wheel end reaches the second power threshold, the control unit 220 controls the wireless charging unit to stop working, and controls the battery at the wheel end to supply power to the tire pressure regulating unit 210 through the discharge mode. The value of the second power threshold may be the same as or different from the value of the first power threshold, and the specific value may be adjusted according to the actual application situation, and this application does not impose any restrictions on this.

[0046] The control unit 220 is configured to receive feedback from a driving performance inquiry, where the driving performance inquiry is used to prompt and inquire about expectations for the vehicle's driving performance, and the feedback is used to indicate a result of the driving performance inquiry; determine the expected tire pressure at the wheel end of the vehicle under driving conditions based on the feedback and the vehicle's driving conditions; generate an adjustment signal based on the actual tire pressure and the expected tire pressure indicated by the tire pressure data; and send the adjustment signal to the tire pressure adjustment unit.

[0047] Optionally, the expectations for the driving performance of the vehicle may include, but are not limited to, comfort and economy; the driving performance inquiry may be used to prompt the driver of the vehicle or other relevant personnel with optional options to inquire the driver of the vehicle or other relevant personnel. The options may include the expectations for the driving performance of the vehicle provided by the vehicle, such as comfort and economy. The feedback of the driving performance inquiry may be, for example, the selection made by the driver of the vehicle or other relevant personnel based on the options provided by the driving performance inquiry (such as comfort or economy), that is, the result of the driving performance inquiry.

[0048] Different tire pressures will change the state of the vehicle's wheels, thereby affecting the vehicle's driving performance. For example, when the tire pressure at the wheel end is higher, the contact area between the vehicle's wheels and the ground is reduced, and the vehicle's rolling resistance becomes smaller, which can improve the vehicle's fuel economy or reduce the vehicle's energy consumption. When the tire pressure at the wheel end is lower, the contact area between the vehicle's wheels and the ground increases, and the vehicle's buffering capacity for bumpy roads increases, which can improve the comfort of the vehicle during driving. In the system provided in the embodiment of the present application, the control unit 220 can make the system more humane and intelligent by asking the vehicle driver or other relevant personnel about their expectations for the vehicle's driving performance.

[0049] In some embodiments, the driving performance inquiry can be prompted and inquired to the driver of the vehicle or other relevant personnel through one or more interactive methods such as voice, touch display screen, gesture, etc. Similarly, the feedback of the driver of the vehicle or other relevant personnel to the driving performance inquiry can include, for example, feedback based on one or more interactive methods such as voice, touch display screen, gesture, etc. provided by the system, and this application does not impose any restrictions on this.

[0050] Illustratively, the driving conditions of the vehicle may include, but are not limited to, the vehicle's load, speed, road conditions of the road section where the vehicle is located, the temperature of the wheel end, the degree of wear of the wheel at the tire end, etc. The control unit 220 in the system provided in the embodiment of the present application determines the expected pressure at the wheel end through the feedback of the driving performance inquiry and the driving conditions of the vehicle, which can meet the needs of the vehicle driver or other relevant personnel for comfort or economy during the vehicle driving process, and on the other hand, can ensure the safety and operability of the vehicle under the current driving conditions.

[0051] As described above, the tire pressure regulating unit 210 may include, for example, an air pressure regulating device, which may inflate or deflate the wheel at the wheel end under the control of the regulating signal sent by the control unit 220. In some embodiments, when the tire pressure at the wheel end is higher than the desired tire pressure, the tire pressure regulating unit 210 may include, for example, a pressurizing device, and when the control unit 220 generates an adjustment signal based on the actual tire pressure and the desired tire pressure indicated by the tire pressure data, it may be configured, for example, as follows: if the actual tire pressure is less than the desired tire pressure, a first adjustment signal is generated, and the first adjustment signal is used to control the pressurizing device to perform pressurization on the wheel end so that the actual tire pressure after the pressurization is adapted to the desired tire pressure. The pressurizing device may be, for example, a micro air pump, or any other device that can perform pressurization on the wheel end, and this application does not impose any restrictions on this.

[0052] In some embodiments, the first adjustment signal may also include a first rate signal, which may be used to control the boost rate when the boost device performs boost processing on the wheel end. The value of the boost rate indicated by the first rate signal may be adjusted according to actual application conditions, and this application does not impose any restrictions on this.

[0053] In some embodiments, when the tire pressure at the wheel end is lower than the expected tire pressure, the tire pressure adjustment unit 210 may include a decompression device, and the control unit 220 may be configured to generate an adjustment signal according to the actual tire pressure and the expected tire pressure indicated by the tire pressure data, for example: if the actual tire pressure is greater than the expected tire pressure, a second adjustment signal is generated, and the second adjustment signal is used to control the decompression device to decompress the wheel end so that the actual tire pressure after the decompression treatment is compatible with the expected tire pressure. The decompression device may be, for example, an electromagnetic deflation valve, or any other device that can decompress the wheel end, and this application does not impose any restrictions on this.

[0054] In some embodiments, the second adjustment signal may also include a second rate signal, which may be used to control the decompression rate when the decompression device performs decompression processing on the wheel end. The value of the decompression rate indicated by the second rate signal may be adjusted according to actual application conditions, and this application does not impose any restrictions on this.

[0055] Considering that when a tire at the wheel end has a flat tire, the tire pressure at the wheel end will usually drop rapidly, seriously affecting the safety of the vehicle during driving. In view of this, the rate of change of the actual tire pressure at the wheel end indicated by the tire pressure data can also be monitored to avoid traffic accidents caused by possible flat tires during vehicle driving. In some embodiments, the tire pressure adjustment unit 210 may include a boosting device, and the control unit 220 may be configured to generate an adjustment signal according to the actual tire pressure and the expected tire pressure indicated by the tire pressure data, for example: if the rate of change of the actual tire pressure within a preset time period exceeds the change rate threshold, a third adjustment signal is generated, and the third adjustment signal is used to control the boosting device to perform emergency boosting on the wheel end, so that the actual tire pressure after the boosting treatment is adapted to the expected tire pressure. Among them, the length of the time period indicated by the preset time period and the value of the change rate threshold can be adjusted according to the actual application situation, and this application does not impose any restrictions on this.

[0056] In some embodiments, the third adjustment signal may also include a third rate signal, which may be used to control the boost rate when the boost device performs emergency boosting on the wheel end. The value of the boost rate indicated by the third rate signal may be adjusted according to actual application conditions, and this application does not impose any restrictions on this.

[0057] In some embodiments, the boost rate indicated by the third rate signal may be greater than the boost rate indicated by the second rate signal, for example.

[0058] In order to improve the operability and safety of the vehicle during driving, the system for adjusting the vehicle tire pressure provided in the embodiment of the present application may also include a display unit, and the control unit 220 is also configured to generate prompt information according to the actual tire pressure at the wheel end indicated by the tire pressure data; the prompt information is displayed through the display unit, and the prompt information is used to indicate the tire pressure at the wheel end. In some embodiments, the prompt information may include, for example, one or more of text information, picture information, and chart information for indicating the tire pressure at the wheel end. The system provided in the embodiment of the present application allows the driver of the vehicle to know the tire pressure at the wheel end more intuitively, and then adjust the driving operation according to the tire pressure at the wheel end, thereby improving the safety and operability of the vehicle during driving.

[0059] The technical solution provided by the present application, on the one hand, can adjust the tire pressure at the wheel end of a moving vehicle through the cooperation of a control unit and a tire pressure adjustment unit at the wheel end, which can effectively deal with abnormal changes in tire pressure that may occur in a moving vehicle and ensure the safety of the vehicle. On the other hand, the technical solution provided by the present application can also determine the expected tire pressure of the vehicle under different driving conditions based on the feedback of driving performance inquiries and the driving conditions of the vehicle, and dynamically adjust the actual tire pressure of the vehicle based on the expected tire pressure, so that the actual tire pressure of the vehicle can be adjusted according to the changes in driving conditions to ensure the safety of the vehicle; and on the basis of ensuring safety, other requirements such as comfort and economy of the vehicle can be further met based on the feedback of driving performance inquiries.

[0060] In some other possible implementations, the present application also provides a method for regulating vehicle tire pressure. Figure 3 is a flow chart of a method for adjusting vehicle tire pressure provided by an embodiment of the present application, the method is executed by a control unit in a system for adjusting vehicle tire pressure, the system comprising a control unit and a tire pressure adjustment unit located at a wheel end.
