Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a tire integrated control system for an ultra-heavy multi-axle off-road vehicle. Background Technology

[0002] Vehicles often travel on complex road conditions, frequently encountering muddy and soft surfaces. According to vehicle ground mechanics theory, given a constant coefficient of friction and other conditions, a larger tire contact patch results in greater traction. Therefore, adjusting tire pressure alters the contact patch, thus changing traction and improving road passability. Meanwhile, tire pressure abnormalities are recognized worldwide as the leading cause of death. Traffic authorities report that approximately 46% of highway accidents are caused by abnormal tire pressure, with 75% of these being blowouts due to low pressure or leaks. The fatality rate for tire blowouts at high speeds exceeds 70%. Consequently, Tire Pressure Monitoring Systems (TPMS) have become standard equipment on most car brands, instantly detecting tire pressure and temperature, analyzing the data, and sending it to the instrument panel for timely detection of tire abnormalities.

[0003] However, tire blowout warning systems can only provide warnings, not timely and effective solutions. For example, heavy-duty multi-axle off-road vehicles have different tire pressure requirements in different driving modes, but current technology uses two independent systems for tire inflation / deflation and tire pressure monitoring, which are not integrated. These systems are typically from different manufacturers, leading to communication delays. Therefore, current technology can only adjust tire pressure when the vehicle is stationary, failing to automatically adjust tire pressure during various driving conditions, significantly reducing the vehicle's off-road performance. Summary of the Invention To address, or partially address, the technical problem of reduced off-road performance caused by the inability of existing technologies to automatically adjust tire pressure during various road conditions, this invention provides a tire integrated control system for an ultra-heavy-duty multi-axle off-road vehicle. This system integrates tire pressure detection and tire inflation / deflation into a single, coordinated design to avoid data delays. Based on this, during the ultra-heavy-duty multi-axle off-road vehicle's operation in the target road condition mode, the system provides real-time feedback on tire status and adaptively adjusts the tire pressure of each tire using a single-wheel, single-control approach. This enables automatic tire pressure adjustment for the ultra-heavy-duty multi-axle off-road vehicle in various road condition modes, significantly reducing the occurrence of tire blowouts and thus greatly improving the vehicle's off-road performance. To address the aforementioned technical problems, a first aspect of the present invention discloses a tire integrated control system for an ultra-heavy-duty multi-axle off-road vehicle.

The N sets of wheel-side valve assemblies are used to monitor the actual tire pressure of the corresponding tires when the super-heavy multi-axle off-road vehicle is in the target road condition mode and traveling within the set speed range; wherein, the target road condition mode is one of the following: highway road condition mode, off-road road condition mode, desert road condition mode, and emergency road condition mode. The controller assembly is used to generate a tire pressure adjustment command for each tire in the target road condition mode by referring to the target tire pressure value of each tire in the target road condition mode and the actual tire pressure of each tire. Each of the N central control valve assemblies is used to automatically inflate and deflate the tires on both sides of the axle in a single-wheel, single-control manner according to the tire pressure adjustment commands of the tires on both sides of the axle, so as to realize the automatic tire pressure adjustment of the super heavy-duty multi-axle off-road vehicle during driving in various road conditions.

Exhaust vents are used to control the exhaust of air from the tires on both sides of the axle into the external environment. The control component is used to control the opening and closing ratio of the first tire control port and the second tire control port according to the tire pressure adjustment commands of the tires on both sides of the axle, so as to perform different degrees of inflation and deflation operations on the tires on both sides of the axle.

[0006] Optionally, the wheel-side valve assembly is designed with a wheel-side valve interface, which is connected between the corresponding central control valve assembly and the corresponding tire, and is used to automatically open when the intake pressure reaches the set pressure to transmit the air source gas to the tire.

[0007] Optionally, the wheel-side valve assembly is equipped with a locking valve to close the air pipe passage and ensure tire sealing when tire pressure regulation fails.

[0008] Optionally, the controller assembly is specifically used to determine the inflation / deflation time of each tire by referring to the target tire pressure value of each tire in the target road condition mode and the actual tire pressure; and to generate a tire pressure adjustment command for each tire in the target road condition mode based on the inflation / deflation time of each tire.

[0009] Optionally, the system further includes: a display and control touch screen terminal, connected to the controller assembly, for displaying the actual tire pressure of each tire, or the inflation / deflation progress of each central control valve assembly.

[0010] Optionally, the display and control touch screen terminal has a one-touch inflation / deflation button for receiving one-touch inflation / deflation operations from the user.

[0011] Optionally, each wheel-side valve assembly integrates a tire pressure monitoring component to monitor the actual tire pressure of the corresponding tire.

[0012] A second aspect of the present invention discloses an ultra-heavy multi-axle off-road vehicle, including the tire integrated control system of the ultra-heavy multi-axle off-road vehicle described in the first aspect.

[0013] Through one or more technical solutions of the present invention, the present invention has the following beneficial effects or advantages: This invention provides a tire integrated control system for an ultra-heavy-duty multi-axle off-road vehicle, integrating N central control valve assemblies and N wheel-side valve assemblies into a single system. This allows the system to simultaneously support tire pressure detection and tire inflation / deflation operations, avoiding data delays. Furthermore, during the ultra-heavy-duty multi-axle off-road vehicle's operation in the target road condition mode, the system provides real-time feedback on tire status and adaptively adjusts the tire pressure of each tire using a single-wheel, single-control method. This achieves automatic tire pressure adjustment for the ultra-heavy-duty multi-axle off-road vehicle under various road condition modes, significantly reducing the occurrence of tire blowouts and greatly improving the vehicle's off-road performance.

[0014] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0017] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0018] Firstly, such as Figure 1 As shown in the embodiment of the present invention, a tire integrated control system for an ultra-heavy multi-axle off-road vehicle is provided. This system can perform inflation, deflation, pressure testing, and pressure maintenance operations on any tire in the cab when the vehicle is parked or running at low speed (no higher than 30 km / h), thereby realizing automatic inflation and deflation during low-speed vehicle operation and improving the vehicle's off-road performance.

[0019] The system includes: a display and control touch screen terminal 101, a controller assembly 102, N central control valve assemblies 103, and N sets of wheel-side valve assemblies 104, where N ≥ 1 and is a positive integer. The display and control touch screen terminal 101 is connected to the controller assembly 102; the controller assembly is connected to the N central control valve assemblies 103 via wiring harnesses, achieving an architecture where one controller assembly 102 controls all central control valve assemblies 103. In practical applications, one controller assembly 102 has the capability to manage the inflation and deflation of 2 to 10 sets of tires.

[0020] The configuration of the central control valve assembly 103, wheel-side valve assembly 104, and tires is 1:2:2, and the central control valve assembly 103, wheel-side valve assembly 104, and tires are all connected by air pipes.

[0021] Each central control valve assembly 103 is connected to a set of wheel-side valve assemblies 104. Each set of wheel-side valve assemblies 104 contains two wheel-side valve assemblies 104, which are respectively installed on the tires on both sides of the axle. That is, one central control valve assembly 103 controls two wheel-side valve assemblies 104, and the two wheel-side valve assemblies 104 control the inflation and deflation of their respective tires. Since the two tires are located on both sides of the axle, the two wheel-side valves are also located on both sides of the axle.

[0022] See Figure 2 This is a diagram showing the tire distribution of an ultra-heavy multi-axle off-road vehicle.

[0023] The super-heavy-duty multi-axle off-road vehicle includes four sets of tires, each set consisting of two tires located on both sides of the axle. In one set, one tire is located on one side of the axle, and the other on the opposite side. For example, in... Figure 2 The eight tires are numbered 1, 2, 3, 4, 5, 6, 7, and 8. Tires 1 and 2 are grouped together, and tires 3 and 4 are grouped together.

[0024] The number of wheel-side valve assemblies 104 is in a 1:1 ratio with the number of tires, and each wheel-side valve assembly 104 integrates a tire pressure monitoring component.

[0025] In the specific control process, the N-group wheel-side valve assembly 104 is used to monitor the actual tire pressure of the corresponding tires when the super-heavy multi-axle off-road vehicle is in the target road condition mode and traveling within the set speed range.

[0026] The target road condition mode is one of the following: highway road condition mode, off-road road condition mode, desert road condition mode, and emergency road condition mode. Specifically, the super-heavy multi-axle off-road vehicle is designed with multiple road condition modes, such as highway road condition mode, off-road road condition mode, desert road condition mode, and emergency road condition mode. These modes are divided according to road conditions, and the super-heavy multi-axle off-road vehicle responds differently to different road condition modes, reflected in aspects such as throttle, speed, and control methods. Of course, other modes can also be defined according to actual conditions; this invention does not limit the types of modes.

[0027] The speed range is set as an example of [0, 80 km / h], but this does not constitute a restriction. When the heavy-duty multi-axle off-road vehicle is in the target road condition mode and traveling within the set speed range, it indicates that the heavy-duty multi-axle off-road vehicle is in the driving state of the target road condition mode.

[0028] Furthermore, each wheel-side valve assembly 104 integrates a tire pressure monitoring component to monitor the actual tire pressure of the corresponding tire, thereby obtaining the actual tire pressure of each tire. In practical applications, the tire pressure monitoring component uses a sensor installed at the air outlet of the wheel-side valve that connects to the tire. Since the tire and the wheel-side valve air outlet are connected and have the same pressure, the tire pressure measured by the sensor directly reflects the actual tire pressure.

[0029] Furthermore, the central control valve assembly 103 and the wheel-side valve assembly 104 can transmit data via wired or wireless means. For example, each wheel-side valve assembly 104 collects the actual tire pressure of its corresponding tire and wirelessly transmits it to the corresponding central control valve assembly 103, which then transmits it to the controller assembly 102 for processing. Of course, the wheel-side valve assembly 104 also has other components for regulating tire pressure, which will be described in detail later and will not be repeated here.

[0030] The controller assembly 102 is used to generate a tire pressure adjustment command for each tire in the target road condition mode by referring to the target tire pressure value of each tire in the target road condition mode and the actual tire pressure of each tire.

[0031] In the specific implementation process, the controller assembly 102 is specifically used to determine the inflation / deflation time of each tire by referring to the target tire pressure value and the actual tire pressure of each tire in the target road condition mode; and to generate a tire pressure adjustment command for each tire in the target road condition mode based on the inflation / deflation time of each tire.

[0032] Different road conditions correspond to different tire pressure target values. Based on the tire pressure target value and the actual tire pressure of each tire, the tire pressure adjustment value of each tire can be calculated.

[0033] Each of the N central control valve assemblies 103 is used to automatically inflate and deflate the tires on both sides of the axle in a single-wheel, single-control manner according to the tire pressure adjustment commands of the tires on both sides of the axle, so as to realize the automatic tire pressure adjustment of the super heavy-duty multi-axle off-road vehicle during driving in various road conditions.

[0034] Specifically, a central control valve assembly 103 is used to control the inflation and deflation of the two tires on both sides of the wheel. Each tire on both sides of the wheel corresponds to a tire pressure adjustment command, which carries a tire pressure adjustment value. After receiving the tire pressure adjustment command corresponding to each tire on both sides of the wheel, the central control valve assembly 103 controls the corresponding tire to perform inflation and deflation operations according to the tire pressure adjustment value carried in the command, through the wheel-side valve assemblies 104 on both sides of the wheel, thereby realizing the tire pressure adjustment for the corresponding tire.

[0035] By integrating N central control valve assemblies 103 and N wheel-side valve assemblies 104 into a single system, the system simultaneously supports tire pressure monitoring and tire inflation / deflation operations to avoid data delays. Based on this, during the driving of the ultra-heavy multi-axle off-road vehicle in the target road condition mode, the system provides real-time feedback on tire status and adaptively adjusts the tire pressure of each tire using a single-wheel, single-control method. This achieves automatic tire pressure adjustment for the ultra-heavy multi-axle off-road vehicle in various road condition modes, significantly reducing the occurrence of tire blowouts in various road condition modes, thereby greatly improving the vehicle's off-road performance.

[0036] To further illustrate and explain the present invention, a detailed description is provided below.

[0037] In an optional embodiment, the system further includes: an air tank connected to each of the central control valve assemblies 103, wherein the number of air tanks and hollow valve assemblies is configured in a 1:N ratio, and the air tanks and each central control valve assembly 103 are connected by an air pipe for supplying gas to the central control valve assembly 103.

[0038] All central control valve assemblies 103 in this embodiment have the same structure. In order to realize the functions of inflation, deflation, pressure holding and pressure measurement, the central control valve assembly 103 integrates a control component. It is connected to the controller assembly 102 through CAN communication and receives the tire pressure adjustment command from the controller assembly 102 to realize any of the functions of inflation, deflation, pressure holding and pressure measurement.

[0039] In the specific implementation process, each central control valve assembly 103 is designed with: air pipeline interface, air source monitoring component, first tire control air port and second tire control air port, exhaust port, and control component.

[0040] An air pipeline interface is used to connect to the air tank in order to provide an air source for the tires.

[0041] The gas source monitoring component, located at the gas pipeline interface, is used to monitor the real-time gas source pressure.

[0042] There are two tire control ports: a first tire control port and a second tire control port. The first tire control port is connected to a wheel-side valve assembly 104 on one side of the axle, and the second tire control port is connected to a wheel-side valve assembly 104 on the other side of the axle. The two tire control ports are connected to the wheel-side valves on both sides of the axle to control the transmission flow of air source gas according to the tire pressure adjustment value, thereby performing inflation and deflation operations on both tires.

[0043] The exhaust port is directly connected to the atmosphere and is used to control the tires on both sides of the axle to exhaust air into the external environment, thereby achieving rapid exhaust for tire pressure relief and pressure maintenance.

[0044] A control component is used to control the opening and closing of the air passage interface, the tire control air ports on both sides of the axle, and the exhaust port based on the tire pressure adjustment command.

[0045] Furthermore, based on the tire pressure adjustment commands of the tires on both sides of the axle, the opening and closing ratios of the first tire control air port and the second tire control air port are controlled to perform automatic inflation and deflation in a single-wheel, single-control manner, thereby performing inflation and deflation operations on the tires on both sides of the axle to different degrees.

[0046] Specifically, the control component adjusts the opening and closing ratio of the first tire control air port according to the tire pressure adjustment command corresponding to the first tire control air port. This controls the flow rate of the air source gas according to the tire pressure adjustment value in the tire pressure adjustment command, allowing it to be input to the tire via the wheel-side valve assembly 104 to inflate the tire; or it allows the gas in the tire to be input to the air tank via the wheel-side valve according to the tire pressure adjustment value carried in the tire pressure adjustment command, achieving the deflation operation. At this time, it is necessary to monitor the air pressure value of the air tank in real time to keep it within the safe air pressure threshold to ensure the safety of the air tank. The air pipeline interface can also be controlled in this way, which will not be elaborated here. Of course, in order to quickly deflate and maintain tire pressure, the opening and closing ratio of the vent can also be adjusted according to the tire pressure adjustment command corresponding to the first tire control air port to allow the tire to deflate quickly. Similarly, the control component adjusts the opening and closing ratio of the second tire control air port according to the tire pressure adjustment command corresponding to the second tire control air port. This ensures that the air source gas flow is controlled according to the tire pressure adjustment value in the tire pressure adjustment command, allowing it to be input to the tire via the wheel-side valve assembly 104 to inflate the tire; or, it allows the gas in the tire to be input to the air tank via the wheel-side valve according to the tire pressure adjustment value carried in the tire pressure adjustment command, achieving the deflation operation. In this case, the air pressure value in the air tank needs to be monitored in real time to ensure it remains within the safe air pressure threshold, thus guaranteeing the safety of the air tank. The air pipeline interface can also be controlled in this manner, which will not be elaborated upon here. To enable rapid deflation and pressure holding of the tire, the opening and closing ratio of the vent can also be adjusted according to the tire pressure adjustment command corresponding to the second tire control air port, allowing for rapid deflation of the tire.

[0047] It is worth noting that the control components in the central control valve assembly 103 are capable of handling the inflation and deflation operations of the tires on both sides of the axle in parallel, so that the tires on both sides of the axle meet their respective target tire pressures.

[0048] In one alternative implementation, the wheel-side valve assembly 104 is designed with: a wheel-side valve interface, an external air source interface, and a tire locking valve.

[0049] The wheel-side valve interface is connected between the corresponding central control valve assembly 103 and the corresponding tire, and is used to automatically open when the intake pressure reaches the set pressure to transmit the gas source gas to the tire.

[0050] An external air source interface allows for manual inflation when automatic tire pressure regulation fails. For example, the external air source interface can be opened to inflate the tires using an external air source.

[0051] The tire locking valve is used to close the air passage and ensure tire sealing when tire pressure regulation fails. The locking valve is manually controlled for pressure maintenance.

[0052] In one optional implementation, the system further includes a display and control touch screen terminal 101, connected to the controller assembly 102, for displaying the actual tire pressure of each tire, or the inflation / deflation progress of each central control valve assembly 103.

[0053] Specifically, the controller assembly 102 and the display touchscreen terminal 101 are connected via a CAN 2.0B wiring harness for CAN 2.0B communication, information processing, and command issuance. For example, the display touchscreen terminal 101 displays a one-touch inflation / deflation button to receive one-touch inflation / deflation operations from the user. When the user presses the one-touch inflation / deflation button, an inflation / deflation command is generated and sent to the controller assembly 102.

[0054] In addition, the display and control touch screen terminal 101 is also used to display the actual tire pressure in real time, or the inflation / deflation progress of each of the central control valve assemblies 103. For example, the tire pressure monitoring component communicates wirelessly with the corresponding central control valve assembly 103, and the monitored actual tire pressure is transmitted from the central control valve assembly 103 to the controller assembly 102 and reported to the display and control touch screen terminal 101 for real-time updates.

[0055] The system of this invention is applicable to both automatic and manual control modes, both of which can adjust tire pressure. In automatic control mode, it includes several road condition modes: highway, off-road, desert, and emergency.

[0056] During tire pressure adjustment, the tire pressure monitoring component integrated in the wheel-side valve assembly 104 detects the actual tire pressure and sends it to the controller assembly 102 via the central control valve assembly 103. The controller assembly 102 updates the actual tire pressure of each tire to the display touch screen terminal 101 in real time. Simultaneously, referencing the target tire pressure value for each tire in the target road condition mode and the actual tire pressure, it generates a tire pressure adjustment command for each tire in the target road condition mode and controls the central control valve assembly 103 to perform tire pressure adjustment operations for each tire.

[0057] In manual control mode, the target tire pressure value can be set arbitrarily by the user to achieve the desired operation. During implementation, the user can maintain tire pressure by manually locking the wheel valves, or manually operate the relevant valves to release air from the tires.

[0058] In this embodiment of the invention, the system can perform operation on any tire using both automatic and manual control modes. In automatic control mode, it can control tire pressure for four road conditions.

[0059] To further illustrate and explain the present invention, the following embodiments are provided as examples from practical applications.

[0060] In practical applications, the tire integrated control system of an ultra-heavy multi-axle off-road vehicle includes one controller assembly 102, four central control valve assemblies 103, eight wheel-side valve assemblies 104, control wiring harnesses, and air pipes.

[0061] The controller assembly 102 is connected to the vehicle platform's display and control touchscreen terminal 101 via a CAN 2.0B wiring harness. It receives commands from the touchscreen terminal 101 to perform corresponding inflation / deflation actions and feeds back the inflation / deflation progress, tire pressure data, and tire temperature data to the touchscreen terminal 101 for display. Furthermore, a tire pressure monitoring component is installed at the air outlet where the wheel-side valve connects to the tire. It can directly measure tire pressure and wirelessly transmit the data to the central control valve assembly 103, and further transmit it to the touchscreen terminal 101 for real-time tire measurement updates. Similarly, a tire temperature monitoring component can be set up to monitor the real-time tire temperature.

[0062] The controller assembly 102 sets the tire pressure adjustment range: the air source pressure is 0.79MPa~0.83MPa, and the set pressure adjustment range is 0.21MPa~0.55MPa. In several road condition modes, including highway, off-road, desert, and emergency, the target tire pressure value corresponding to each road condition mode can be selected from the set pressure adjustment range.

[0063] If the controller assembly 102 calculates that the tire needs inflation based on the actual tire pressure and the target tire pressure, then during the inflation operation, the controller assembly 102 energizes the central control valve assembly 103, opening the air pipe interface and tire control air ports to connect the air hose to the wheel-side valve assembly 104. When the intake pressure of the wheel-side valve assembly 104 reaches the set pressure, the wheel-side valve interface automatically opens to inflate the tire, and the valve assemblies close after the inflation time is reached. It is worth noting that the opening and closing ratio of the air pipe interface and different tire control air ports is determined by the tire pressure adjustment command of the corresponding tire.

[0064] If the controller assembly 102 calculates that the tire needs to maintain pressure based on the actual tire pressure value and the target tire pressure value, the wheel-side valve interface, external air source interface, and tire locking valve in the wheel-side valve assembly 104 will automatically close to achieve automatic pressure maintenance.

[0065] If the controller assembly 102 calculates that the tire needs to be deflated based on the actual tire pressure value and the target tire pressure value, the vent in the central control valve assembly 103 remains open under the set back pressure and continues to deflate until the target tire pressure value is reached and then closes.

[0066] The above describes the tire integrated control system for an ultra-heavy-duty multi-axle off-road vehicle disclosed in this invention. By integrating the controller assembly 102, the central control valve assembly 103, and the wheel-side valve assembly 104 into the same system, the hardware and software integration of tire pressure detection and inflation / deflation operations for the ultra-heavy-duty multi-axle off-road vehicle is achieved. This ensures the inflation / deflation indicators of heavy-duty large tires and enables inflation / deflation while driving under different road conditions, greatly enhancing off-road performance. Of course, timely monitoring and adjustment of tire conditions can also improve wheel safety, which has significant reference and promotion value. Furthermore, based on the control architecture of the same controller assembly 102, N central control valve assemblies 103, and 2N wheel-side valve assemblies 104, the inflation / deflation control can be expanded, thereby greatly enhancing vehicle adaptability.

The specific implementation process can be referred to the system embodiments provided in the first aspect above, and will not be described in detail here.
