[0042] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0043] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0044] The following is combined Figures 1-7 The tire pressure control method, vehicle controller, tire pressure control system, storage medium, program product, and vehicle according to embodiments of the present invention are described in detail.

[0045] Reference Figure 1As shown, the tire pressure control method according to an embodiment of this application includes: controlling the tire pressure of the vehicle based on road condition information of the current road surface and user instruction information; wherein, the user instruction information includes tire pressure adjustment parameters input by the user. When driving on different road surfaces (ordinary road surface, snow road surface, mud road surface, rock road surface, sand road surface, grass road surface, etc.), the tire pressure needs to be adjusted to maintain optimal performance on different road surfaces. The tire pressure control method according to an embodiment of this application controls the tire pressure based on road condition information of the current road surface and user instruction information, which can adjust the tire pressure of the vehicle to a matching tire pressure value according to user needs and current road conditions, so as to achieve accurate tire pressure adjustment according to different user needs, ensure the driving force of the vehicle, and thus provide users with great convenience and performance improvement under different driving conditions.

[0046] In some embodiments of this application, the tire pressure of a vehicle is controlled based on road condition information and user command information, including: determining a target tire pressure based on the road condition information and user command information; and controlling the tire pressure of the vehicle based on the target tire pressure. Specifically, the target tire pressure is determined based on the user command information and road condition information, and a tire pressure adjustment signal is sent based on the target tire pressure to control the tire pressure of the vehicle to be adjusted to the target tire pressure.

[0047] In some embodiments of this application, determining the target tire pressure of a vehicle based on road condition information and user instruction information includes: determining a first tire pressure signal based on the road condition information; determining a second tire pressure signal based on tire pressure adjustment parameters from the user instruction information; and determining the target tire pressure of the vehicle based on the first tire pressure signal and the second tire pressure signal. The target tire pressure can be determined by the first tire pressure signal corresponding to the road condition information and the second tire pressure signal corresponding to the user instruction information. The determination of the target tire pressure combines the road condition information of the current road surface where the vehicle is located and the user instruction information, enabling the vehicle's tire pressure to be adjusted to a matching value according to user needs and current road conditions, thus achieving accurate tire pressure adjustment based on different user requirements.

[0048] In some embodiments of this application, determining the target tire pressure of a vehicle based on a first tire pressure signal and a second tire pressure signal includes: determining the target tire pressure based on the first tire pressure signal when the first tire pressure signal and the second tire pressure signal match. When the first tire pressure signal corresponding to road condition information and the second tire pressure signal corresponding to user instruction information match, the target tire pressure can be determined based on the first tire pressure signal regardless of whether the second tire pressure signal corresponds to a specific tire pressure or a tire pressure adjustment trend.

[0049] In some embodiments of this application, determining the target tire pressure of a vehicle based on a first tire pressure signal and a second tire pressure signal includes: determining target tire pressure adjustment information when the first tire pressure signal and the second tire pressure signal do not match; and determining the target tire pressure of the vehicle based on the target tire pressure adjustment information. When the first tire pressure signal corresponding to road condition information and the second tire pressure signal corresponding to user command information do not match, determining the target tire pressure based on either the first or second tire pressure signal may not meet the user's tire pressure adjustment needs. In this case, it is necessary to determine the target tire pressure adjustment information, and then determine the target tire pressure of the vehicle based on the target tire pressure adjustment information. This allows for the accurate adjustment of tire pressure according to the user's specific needs by combining the road condition information of the current road surface where the vehicle is located and the user's command information.

[0050] In some embodiments of this application, determining target tire pressure adjustment information when the first tire pressure signal and the second tire pressure signal do not match includes: sending a first prompt message to remind the user when the first tire pressure signal and the second tire pressure signal do not match, and determining the target tire pressure adjustment information based on the user's response to the first prompt message. For example, the first prompt message can be sent to a display device. The user can respond to the first prompt message on the display device. Optionally, the user's response to the first prompt message may include: selecting road condition information as the target tire pressure adjustment information, selecting current user command information as the target tire pressure adjustment information, or changing other user command information as the target tire pressure adjustment information.

[0051] In some embodiments of this application, determining a first tire pressure signal based on road condition information includes: determining the first tire pressure signal using an AI control model based on the road condition information. Optionally, the AI ​​control model can be a machine learning model, such as a deep neural network (DNN), a Bayesian machine learning model, etc. The AI ​​model can be updated by a server system in response to vehicle driving reports. The updated AI model can be transmitted to the vehicle controller to replace the previous version of the AI ​​model accessed by the vehicle controller.

[0052] In some embodiments of this application, reference is made to Figure 2 As shown, the user instruction information includes automatic mode information. Based on the tire pressure adjustment parameters in the user instruction information, a second tire pressure signal is determined, including: determining the second tire pressure signal based on the tire pressure adjustment parameters corresponding to the preset target gear in the automatic mode information. The automatic mode information refers to the automatic tire pressure adjustment information corresponding to the automatic mode, including the preset target gear for automatic tire pressure adjustment. The tire pressure adjustment parameters corresponding to the preset target gear can correspond to different tire conditions.

[0053] In some embodiments of this application, reference is made to Figure 2As shown, the user instruction information includes manual mode information. Based on the tire pressure adjustment parameters in the user instruction information, a second tire pressure signal is determined, including: determining the second tire pressure signal based on the tire pressure settings corresponding to the manual mode information. The manual mode information refers to the manual tire pressure adjustment information corresponding to the manual mode. Optionally, the tire pressure settings in the manual mode information may include: increasing tire pressure settings, decreasing tire pressure settings, and inputting a target tire pressure setting, etc.

[0054] In some embodiments of this application, reference is made to Figure 3 As shown, the user instruction information includes tire pressure holding mode information. Based on the target tire pressure, the vehicle's tire pressure is controlled, including: based on the tire pressure holding signal in the tire pressure holding mode information, after the vehicle's tire pressure reaches the target tire pressure, controlling the vehicle's tire pressure to maintain the target tire pressure. The tire pressure holding mode information refers to the tire pressure holding adjustment information corresponding to the tire pressure holding mode. Optionally, the tire pressure holding mode is a sub-mode of automatic or manual mode.

[0055] Tire pressure can fluctuate due to factors such as altitude and temperature, necessitating real-time tire pressure maintenance to maintain tire pressure balance. In real-time tire pressure maintenance mode, the vehicle controller, based on the tire pressure maintenance signal, continuously controls the tire pressure after the target tire pressure is reached, ensuring the tire pressure is maintained in real time. Specifically, after reaching the target tire pressure, the tire pressure control component can maintain the tire pressure at the target pressure based on real-time monitoring. Optionally, after reaching the target tire pressure, if the tire pressure of any tire is lower than the target pressure, the tire pressure control component inflates the corresponding tire; if the tire pressure of any tire is higher than the target pressure, the tire pressure control component deflates the corresponding tire; and when the tire pressure of any tire equals the target tire pressure, the tire pressure control component is deactivated.

[0056] In some embodiments of this application, reference is made to Figure 4The user instruction information includes target steering information. Based on road condition information and user instruction information, the target tire pressure of the vehicle is determined, including: when the vehicle is in target steering mode, determining a first target tire pressure based on road condition information and user instruction information; adjusting the first target tire pressure to a second target tire pressure, and using the second target tire pressure as the target tire pressure; wherein the second target tire pressure is a tire pressure different from the first target tire pressure. When the vehicle is in target steering mode, if the vehicle performs the target steering function according to the first target tire pressure, it is easy to cause the vehicle to generate greater friction noise and wear the vehicle tires. At this time, adjusting the target tire pressure from the first target tire pressure to a second target tire pressure different from the first target tire pressure allows the vehicle to drive in the target steering mode and under the current road conditions with less noise generated by the tires against the ground, less tire wear, and higher vehicle stability. Optionally, the second target tire pressure is a tire pressure value or tire pressure adjustment value set based on road condition information in target steering mode. Optionally, when the vehicle is in target steering mode, a fourth prompt message is sent to remind the user whether to perform tire pressure control.

[0057] In some embodiments of this application, the target steering mode includes at least one of a U-turn mode and a large-angle turn mode.

[0058] In some embodiments of this application, the tire pressure control method further includes: adjusting the target tire pressure from a second target tire pressure value to a first target tire pressure value when the vehicle exits the target steering mode. When the vehicle exits the target steering mode, the second target tire pressure value is not the ideal tire pressure that matches the current driving state. At this time, adjusting the target tire pressure from the second target tire pressure value to the first target tire pressure value makes the target tire pressure match the driving conditions, thereby ensuring the vehicle's driving force.

[0059] In some embodiments of this application, the vehicle's tires are connected to a tire pressure control assembly via air hoses. Controlling the vehicle's tire pressure according to a target tire pressure includes: sending a tire pressure adjustment signal to the tire pressure control assembly based on the target tire pressure and the vehicle's current tire pressure, so as to adjust the tire pressure to the target tire pressure via the tire pressure control assembly. The tire pressure control assembly can adjust the tire pressure to the target tire pressure according to the tire pressure adjustment signal. The tire pressure control assembly is connected to the vehicle controller and the tires, and is used to adjust the tire pressure to the target tire pressure according to the tire pressure adjustment signal sent by the vehicle controller. The target tire pressure is the vehicle's tire pressure determined based on road condition information and user command information.

[0060] In some embodiments of this application, a tire pressure sensor is connected between the tire and the vehicle controller to collect the current tire pressure. Optionally, the vehicle's domain controller transmits the current tire pressure collected by the tire pressure sensor to the vehicle controller.

[0061] In some embodiments of this application, a tire pressure adjustment signal is sent to a tire pressure control component based on a target tire pressure and the vehicle's current tire pressure, so as to adjust the tire pressure to the target tire pressure via the tire pressure control component. This includes: comparing the vehicle's current tire pressure with the target tire pressure; and, if the current tire pressure and the target tire pressure are different, sending an inflation adjustment signal and / or a deflation adjustment signal to the tire pressure control component to adjust the tire pressure to the target tire pressure.

[0062] In some embodiments of this application, when the current tire pressure differs from the target tire pressure, an inflation adjustment signal and / or a deflation adjustment signal are sent to the tire pressure control component to adjust the tire pressure to the target tire pressure. This includes: when the target tire pressure is lower than the current tire pressure, sending a deflation adjustment signal to the tire pressure control component to adjust the tire pressure to the target tire pressure; and / or, when the target tire pressure is higher than the current tire pressure, sending an inflation adjustment signal to the tire pressure control component to adjust the tire pressure to the target tire pressure. Thus, the tire pressure can be adjusted based on control signals from the vehicle controller using the tire pressure control component.

[0063] In some embodiments of this application, when a vehicle's tires experience an unexpected air leak (such as a puncture or blowout), the tire pressure drops at an abnormal rate. At this time, the rate of tire leakage is determined, and the tire pressure is adjusted based on the rate of leakage to suppress problems such as wheel misalignment caused by tire leakage.

[0064] In some embodiments of this application, reference is made to Figure 5 As shown, the tire pressure control method further includes: when the tire pressure drop rate of the vehicle's tires is less than or equal to a preset speed, sending a second prompt message to remind the user, and determining whether to perform tire pressure control based on the user's response to the second prompt message; when the tire pressure drop rate of the vehicle's tires is greater than the preset speed, sending a third prompt message to remind the user to stop. Optionally, the second prompt message may include prompting the user about abnormal tire pressure, whether to activate tire pressure compensation, whether to stop, and / or prompting the user to repair the vehicle, etc.; the user's response to the second prompt message may include selecting automatic mode, selecting tire pressure holding mode, and / or continuing to drive, etc. Optionally, the preset speed is the maximum inflation speed of a single tire.

[0065] In some embodiments of this application, the vehicle-mounted radar and image acquisition device are respectively connected to the vehicle controller and can be installed on the outer surface of the vehicle. The vehicle-mounted radar can be used to collect environmental information about the vehicle's current location. After receiving the environmental information, the vehicle controller can determine whether it is permissible to operate the image acquisition device to obtain a road surface image of the road where the vehicle is currently located. After receiving the road surface image, the vehicle controller can perform image recognition on the road surface image to obtain road condition information about the road where the vehicle is currently located. In some embodiments of this application, the tire pressure control method further includes: performing image recognition on the road surface image of the road where the vehicle is currently located to obtain road condition information about the road where the vehicle is currently located.

[0066] In some embodiments of this application, road condition information includes road surface type. Image recognition is performed on the road surface image of the road surface where the vehicle is currently located to obtain road condition information of the road surface where the vehicle is currently located, including: inputting the road surface image into a pre-trained road surface type classification model to obtain the road surface type of the road surface where the vehicle is currently located.

[0067] In some embodiments of this application, the image acquisition device may include, but is not limited to, cameras, monitoring equipment, etc. After receiving the road surface image sent by the image acquisition device, the vehicle controller identifies the road surface image. Specifically, the image may first undergo preprocessing operations such as noise reduction and brightness adjustment to improve image quality. Then, features are extracted from the preprocessed road surface image to obtain different road surface types. Next, the extracted features are input into a pre-trained road surface type classification model to obtain the road surface type of the road where the vehicle is currently located.

[0068] In some embodiments of this application, the tire pressure control method further includes: identifying road condition information of the road surface where the vehicle is currently located based on the intelligent driving domain control unit.

[0069] According to a second aspect embodiment of the present application, the vehicle controller includes: a memory configured to store instructions; and a processor configured to retrieve instructions from the memory and, when executing the instructions, to implement the above-described tire pressure control method.

[0070] According to the vehicle controller of this application embodiment, the tire pressure control can be performed based on the road condition information of the current road surface and the user command information. The tire pressure can be adjusted to a matching tire pressure value according to the user's needs and the current road conditions, so as to achieve accurate tire pressure adjustment according to different user needs, and ensure the driving force of the vehicle, thereby providing users with great convenience and performance improvement under different driving conditions.

[0071] According to a third aspect embodiment of the present application, the tire pressure control system includes: the vehicle controller 1 described above; and a tire pressure control component 4, which is connected between the vehicle controller 1 and the tires 5 of the vehicle, and is used to adjust the tire pressure of the tires 5 to a target tire pressure according to a tire pressure adjustment signal sent by the vehicle controller 1.

[0072] According to the tire pressure control system of this application embodiment, the tire pressure of the tire 5 can be controlled by the tire pressure control component 4 between the vehicle controller 1 and the tire 5 of the vehicle, so that the tire pressure of the tire 5 is adjusted to the target tire pressure. In this way, the tire pressure of the vehicle can be adjusted to a matching tire pressure value according to the user's needs and the current road conditions, so as to achieve accurate adjustment of tire pressure according to different user needs, ensure the driving force of the vehicle, and thus provide users with great convenience and performance improvement under different driving conditions.

[0073] In some embodiments of this application, reference is made to Figures 6-7 As shown, the tire pressure control assembly 4 includes an air pump 41 and a switching valve 42. The tire 5 is connected to the air pump 41 and the switching valve 42 via an air hose. The air pump 41 and the switching valve 42 are respectively connected to the vehicle controller 1. Specifically, the vehicle controller 1 includes an air pump controller 11 and a switching valve controller 12. The air pump controller 11 is connected to the air pump 41 and controls the air pump 41, while the switching valve controller 12 is connected to the switching valve 42 and controls the switching valve 42. The switching valve 42 is connected to the tire 5 (such as the tire 5's inflation / deflation hub bearing) via an air hose to perform inflation and deflation operations on the tire 5. The air pump 41 controls the switching valve 42 to adjust the tire pressure of the tire 5 to the target tire pressure according to the tire pressure adjustment signal. When the switching valve 42 receives the tire pressure adjustment signal, it can open or close according to the tire pressure adjustment signal, thereby controlling the gas flow in the air hose. For example, when the tire 5 needs to be inflated, the tire pressure adjustment signal is to open the switching valve 42, and gas flows into the tire 5 through the air hose. Conversely, when tire 5 needs to be deflated, the tire pressure regulation signal closes the switch valve 42, and the gas in the air pipe is released to the external environment. Optionally, the switch valve 42 is a solenoid valve. Optionally, the air pump controller 11 and / or the switch valve controller 12 in the vehicle controller 1 are connected to other controllers via CAN or CANFD; the air pump controller 11 is connected to the air pump 41 via CAN or CANFD; the switch valve controller 12 uses a PWM signal to control the switch valve 42.

[0074] In some embodiments of this application, the tire pressure control system further includes a display device 2 connected to the vehicle controller 1, and the display interface of the display device 2 includes operable controls for setting user instruction information.

[0075] According to a fourth aspect of this application, the vehicle includes: the vehicle controller 1 described above, or the tire pressure control system described above.

[0076] The vehicle according to the embodiments of this application can control tire pressure based on road condition information and user command information of the current road surface. It can adjust the tire pressure of the vehicle to a matching tire pressure value according to user needs and current road conditions, so as to achieve accurate tire pressure adjustment according to different user needs, and ensure the driving force of the vehicle, thereby providing users with great convenience and performance improvement under different driving conditions.
