[0049] 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 embodiments described are only 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 those skilled in the art without creative work are within the scope of protection of the present application.

[0050] See also Figure 1 , Figure 1 This is a schematic diagram of an active suspension motion simulation model. Figure 1 As shown in the active suspension motion simulation model, K w Tire stiffness is a factor that plays a role in the equation of motion for the unsprung mass, representing the reaction force exerted by the tire on the unsprung mass. A greater tire stiffness increases the unsprung mass's response to road excitation, altering the dynamic characteristics of the active suspension accordingly.

[0051] Under the same working conditions, the tire stiffness is proportional to the tire pressure. Based on the simplified model of elastic body assumption, the tire is assumed to be an inflated elastic body, and the tire stiffness is proportional to the tire pressure. Where F is the vertical load and z is the vertical deformation of the tire. Further considering the tire pressure p, under the static approximation, the tire contact area A is related to the tire pressure p and the deformation z. Assuming A changes linearly with deformation (simplified as a rectangular contact), then F≈p·A+F 胎体 . F 胎体 The load contributed by the carcass structure does not affect the tire pressure. The radial stiffness of the tire can be expressed as Therefore, under the same working conditions, tire stiffness is proportional to tire pressure.

[0052] Furthermore, tires are the only part of a vehicle that comes into contact with the ground, and tire pressure directly impacts the vehicle's handling and ride comfort. Under the same operating conditions and speed, varying tire pressures can affect the vehicle's vertical acceleration. Vertical acceleration significantly impacts ride comfort, and proper tire pressure can cushion vibrations and enhance the convergence of vehicle body undulations.

[0053] As can be seen, tire pressure has a significant impact on vehicle body motion and comfort evaluation. Based on this, the embodiments of the present application use tire pressure control in the vehicle's jumping function. By changing the tire pressure, the tire rigidity is changed, thereby optimizing the vehicle's jumping ability, increasing the take-off stroke, increasing the leap distance, optimizing the oscillation curve, and increasing landing cushioning.

[0054] For example, if the technical solution provided by the embodiment of the present application is used during a standing jump, the take-off stroke can be increased and the landing comfort can be improved; if the technical solution provided by the embodiment of the present application is used during a leap, the jump span can be increased, the landing impact force can be reduced, and the aftershock convergence after the leap can be enhanced; if the technical solution provided by the embodiment of the present application is used during a passive jump, it can assist in enhancing the comfort control of road preview or encountering obstacles during driving.

[0055] According to a first aspect of the present application, an embodiment of the present application provides a vehicle jumping method.

[0056] See also Figure 2 , Figure 2 Schematic diagram of a vehicle jumping method provided by an embodiment of the present application. Figure 2 As shown, the vehicle jumping method may include the following steps:

[0057] Step S100: During the vehicle jumping process, the tire pressure of the vehicle is adjusted to assist the vehicle jumping.

[0058] The vehicle's jump can be active, such as when a user selects to enable the jump function, or passive, such as when the vehicle passes through a complex road section with rugged obstacles. In some embodiments, the vehicle's jump includes but is not limited to: standing jump, flying jump, passive jump, etc.

[0059] The vehicle can achieve jumping based on a vehicle suspension. The vehicle suspension can be installed between the vehicle body and the wheels. By adjusting the height of the vehicle suspension, the vehicle height can be adjusted, thereby achieving jumping. In some embodiments, the vehicle suspension includes but is not limited to an active suspension that can adjust parameters such as suspension stiffness and damping. In some embodiments, the active suspension includes but is not limited to air suspension, electromagnetic suspension, hydraulic suspension, etc.

[0060] During a jump, embodiments of the present application control the tire pressure of the vehicle to assist the vehicle in jumping, such as assisting with takeoff, touchdown, landing, and ending the jump. Adjusting the tire pressure can alter both tire stiffness and the vehicle's vertical acceleration, thereby optimizing the vehicle's jumping capabilities. These improvements include increasing takeoff travel, increasing leap distance, optimizing the oscillation curve, and increasing landing cushioning, resulting in more efficient and comfortable jumps.

[0061] It should be understood that in the embodiments of the present application, adjusting the tire pressure of a vehicle includes, but is not limited to, increasing the tire pressure of the vehicle, decreasing the tire pressure of the vehicle, or adjusting the tire pressure of the vehicle to a tire pressure threshold. Furthermore, the tire pressure of all tires of the vehicle can be adjusted, or the tire pressure of only some tires of the vehicle can be adjusted, such as adjusting the tire pressure of only the front tires or only the rear tires of the vehicle.

[0062] In some embodiments, the above step S100 may include the following steps:

[0063] Step S110: During the vehicle jumping process, the tire pressure of the vehicle is adjusted to a first tire pressure threshold to assist the vehicle in taking off.

[0064] Adjusting a vehicle's tire pressure can alter tire stiffness, thereby changing the response of the unsprung mass to road excitation and, consequently, the dynamic characteristics of the vehicle's suspension. Consequently, applying tire pressure adjustments during a jump can effectively increase the vehicle's travel, thereby increasing the jump height when jumping from a stationary position and the height and distance of a flying leap.

[0065] To effectively assist the vehicle in launching, in some embodiments, step S110 may include: adjusting the vehicle's tire pressure to a first tire pressure threshold before the vehicle launches to assist the vehicle in launching. The vehicle's tire pressure may be adjusted to the first tire pressure threshold at any time before the vehicle launches. For example, the vehicle's tire pressure may be adjusted to the first tire pressure threshold when the vehicle receives a jump enable instruction, which may be an instruction generated by the user selecting the jump function. For another example, the vehicle's tire pressure may be adjusted to the first tire pressure threshold when the vehicle meets preset conditions, such as when the vehicle calculates the control parameters required for launching.

[0066] The first tire pressure threshold may be a default or preset tire pressure threshold, or a tire pressure threshold determined in real time based on the actual driving state of the vehicle. To improve the accuracy of the first tire pressure threshold, in some embodiments, the vehicle jumping method may further include the following steps:

[0067] Step S010: Determine a first tire pressure threshold value according to the vehicle's driving status data.

[0068] Driving status data is used to indicate the current driving status of the vehicle, such as the status of the vehicle itself or the status of the driving environment. In some embodiments, the driving status data includes but is not limited to at least one of the following: driving mode data, jump function data, and road condition data. Among them, the driving mode data is used to indicate the current driving mode of the vehicle, including but not limited to: sports mode, off-road mode, comfort mode, track mode, etc.; the jump function data is used to indicate the current jump function of the vehicle, including but not limited to: jumping on the spot, leaping, etc.; the road condition data is used to indicate the current road condition of the vehicle, including but not limited to: road friction coefficient, road signal, etc. The road signal is the ratio of the vehicle speed and the wavelength of the road surface roughness when the vehicle is driving on the road. By referring to multi-dimensional driving status data, the accuracy of the first tire pressure threshold can be further improved to effectively optimize the jumping ability for different driving conditions.

[0069] In some embodiments, the above step S010 may include: determining the first tire pressure corresponding to the vehicle's driving status data in the first mapping data as the first tire pressure threshold. The first mapping data includes at least one set of corresponding relationships between driving status data and the first tire pressure. After obtaining the vehicle's driving status data, the first tire pressure corresponding to the vehicle's driving status data can be searched from the first mapping data as the first tire pressure threshold. By presetting the first mapping data, it is helpful to quickly locate the required first tire pressure threshold and improve the efficiency of tire pressure adjustment. The first mapping data can be obtained in advance based on simulation, or obtained based on real vehicle simulation or real vehicle driving, or obtained based on empirical data, and this embodiment of the present application does not limit this.

[0070] In some embodiments, the above step S100 may include the following steps:

[0071] Step S120: During the vehicle jumping process, the tire pressure of the vehicle is adjusted to a second tire pressure threshold to assist the vehicle in touching the ground.

[0072] Adjusting a vehicle's tire pressure can alter tire stiffness, thereby changing the response of the unsprung mass to road excitation and modifying the dynamic characteristics of the vehicle's suspension. Furthermore, adjusting tire pressure can alter the vehicle's vertical acceleration, thereby providing shock absorption and damping. Therefore, applying tire pressure adjustments at touchdown can effectively increase landing cushioning, achieve a shock-absorbing effect, and improve the comfort of the vehicle during the descent.

[0073] To effectively assist the vehicle in touching down, in some embodiments, the above-mentioned step S120 may include: when the vehicle's jump height satisfies the first jump condition, adjusting the vehicle's tire pressure to a second tire pressure threshold. By comparing the vehicle's jump height with the first jump condition, it can be ensured that the vehicle's tire pressure is adjusted to the second tire pressure threshold after the vehicle takes off, so as to avoid affecting the take-off ability. The embodiments of the present application do not limit the specific setting of the jump height. In actual application, it can be flexibly set according to needs. In some embodiments, the jump height may refer to the height between the wheel arch and the wheel center of the vehicle. For other introductions and descriptions of the jump height, please refer to the following embodiments, which will not be elaborated here.

[0074] In some embodiments, the first jump condition includes the vehicle's jump height being equal to a target height threshold. The target height threshold may be the maximum jump height the vehicle is expected to reach; alternatively, the target height threshold may be an arbitrarily set jump height. By comparing the vehicle's current jump height with the target height threshold, a determination is made as to whether the vehicle's tire pressure should be adjusted to a second tire pressure threshold. This ensures that the vehicle's tire pressure is adjusted to the second tire pressure threshold before the vehicle contacts the ground after taking off, effectively assisting the vehicle in ground contact.

[0075] The target height threshold may be a default or preset height threshold, or a height threshold determined in real time based on the actual driving state of the vehicle. To improve the accuracy of the target height threshold, in some embodiments, the vehicle jumping method may further include the following steps:

[0076] Step S000: Determine a target height threshold according to the vehicle's driving status data.

[0077] In some embodiments, the driving state data includes but is not limited to at least one of the following: driving mode data, jump function data, and road condition data. For other descriptions of the vehicle's driving state data, please refer to the description of step S010 above, which will not be repeated here.

[0078] In some embodiments, the above step S000 may include: determining the target height corresponding to the vehicle's driving status data in the target mapping data as a target height threshold. The target mapping data includes at least one set of corresponding relationships between driving status data and target heights. After obtaining the vehicle's driving status data, the target height corresponding to the vehicle's driving status data can be searched from the target mapping data as the target height threshold. By presetting the target mapping data, it is helpful to quickly locate the required target height threshold and improve the efficiency of tire pressure adjustment. The target mapping data may be obtained in advance based on simulation, or may be obtained based on real vehicle simulation or real vehicle driving, or may be obtained based on empirical data, and this is not limited in the embodiments of the present application.

[0079] The second tire pressure threshold may be a default or preset tire pressure threshold, or a tire pressure threshold determined in real time based on the actual driving state of the vehicle. To improve the accuracy of the second tire pressure threshold, in some embodiments, the vehicle jumping method may further include the following steps:

[0080] Step S020: Determine a second tire pressure threshold value according to the vehicle's driving status data.

[0081] In some embodiments, the driving state data includes but is not limited to at least one of the following: driving mode data, jump function data, and road condition data. For other descriptions of the vehicle's driving state data, please refer to the description of step S010 above, which will not be repeated here.

[0082] In some embodiments, the above-mentioned step S020 may include: determining the second tire pressure corresponding to the vehicle's driving status data in the second mapping data as the second tire pressure threshold. The second mapping data includes at least one set of corresponding relationships between driving status data and the second tire pressure. After obtaining the vehicle's driving status data, the second tire pressure corresponding to the vehicle's driving status data can be searched from the second mapping data as the second tire pressure threshold. By presetting the second mapping data, it is helpful to quickly locate the required second tire pressure threshold and improve the efficiency of tire pressure adjustment. The second mapping data can be obtained in advance based on simulation, or can be obtained based on real vehicle simulation or real vehicle driving, or can be obtained based on empirical data, and this embodiment of the present application does not limit this.

[0083] In some embodiments, the above step S100 may include the following steps:

[0084] Step S130: During the vehicle jumping process, the tire pressure of the vehicle is adjusted to a third tire pressure threshold to assist the vehicle in landing.

[0085] Adjusting a vehicle's tire pressure can alter tire stiffness, thereby changing the response of the unsprung mass to road excitation and modifying the dynamic characteristics of the vehicle's suspension. Furthermore, adjusting tire pressure can alter the vehicle's vertical acceleration, thereby enhancing the convergence of body undulations. Based on this, applying tire pressure adjustment at touchdown can effectively converge aftershocks after the impact of touchdown, rapidly reducing oscillations.

[0086] To effectively assist the vehicle in landing, in some embodiments, the above-mentioned step S130 may include: when the vehicle's jump height satisfies the second jump condition, adjusting the vehicle's tire pressure to a third tire pressure threshold. By comparing the vehicle's jump height with the second jump condition, it can be ensured that the vehicle's tire pressure is adjusted to the third tire pressure threshold after the vehicle touches the ground, so as to avoid affecting the landing cushioning capacity when touching the ground. The embodiments of the present application do not limit the specific setting of the jump height. In actual application, it can be flexibly set according to needs. In some embodiments, the jump height may refer to the height between the wheel arch and the wheel center of the vehicle. For other introductions and descriptions of the jump height, please refer to the following embodiments, which will not be elaborated here.

[0087] It should be understood that when a vehicle jumps, the shock absorbers (e.g., springs) in the vehicle's suspension accumulate force and compress. As the jump begins, the shock absorbers begin to stretch, and the jump height begins to increase. At the highest jump height, the shock absorbers are stretched to their maximum length, and the vehicle is completely off the ground. The vehicle then descends. At the moment of contact with the ground, the shock absorbers are not yet compressed, and their point of contact with the ground is the vehicle's impact point. Under the influence of the vehicle's gravity, the shock absorbers compress, and the vehicle body is also pressed against the ground, at which point the jump height begins to decrease. During the jump, the shock absorbers sequentially undergo the following processes: force accumulation (compression), takeoff (stretching), contact (beginning to compress), gravity (compression), and recovery. Contact refers to the moment the shock absorbers begin to compress at the time of landing impact, but have not yet been compressed, while landing refers to the process of shock absorber compression after the landing impact. Alternatively, contact refers to the moment the jump height begins to decrease at the time of landing impact, but has not yet decreased, while landing refers to the process of the jump height decreasing after the landing impact.

[0088] Based on this, in some embodiments, the second jump condition includes the first decrease in jump height, such as the first decrease in jump height after reaching a target height threshold. By monitoring whether the vehicle's jump height decreases, it is determined whether to adjust the vehicle's tire pressure to the third tire pressure threshold. This ensures that the vehicle's tire pressure is adjusted to the third tire pressure threshold after the vehicle lands, avoiding affecting the landing cushioning capability at touchdown and effectively assisting the vehicle in landing.

[0089] The third tire pressure threshold may be a default or preset tire pressure threshold, or a tire pressure threshold determined in real time based on the actual driving state of the vehicle. To improve the accuracy of the third tire pressure threshold, in some embodiments, the vehicle jumping method may further include the following steps:

[0090] Step S030: Determine a third tire pressure threshold value according to the vehicle's driving status data.

[0091] In some embodiments, the driving state data includes but is not limited to at least one of the following: driving mode data, jump function data, and road condition data. For other descriptions of the vehicle's driving state data, please refer to the description of step S010 above, which will not be repeated here.

[0092] In some embodiments, the above step S030 may include: determining the third tire pressure corresponding to the vehicle's driving status data in the third mapping data as the third tire pressure threshold. The third mapping data includes at least one set of corresponding relationships between driving status data and the third tire pressure. After obtaining the vehicle's driving status data, the third tire pressure corresponding to the vehicle's driving status data can be searched from the third mapping data as the third tire pressure threshold. By presetting the third mapping data, it is helpful to quickly locate the required third tire pressure threshold and improve the efficiency of tire pressure adjustment. The third mapping data can be obtained in advance based on simulation, or can be obtained based on real vehicle simulation or real vehicle driving, or can be obtained based on empirical data, and this embodiment of the present application does not limit this.

[0093] In some embodiments, the above step S100 may include the following steps:

[0094] Step S140: During the vehicle jumping process, the tire pressure of the vehicle is adjusted to a fourth tire pressure threshold to assist the vehicle in completing the jump.

[0095] In order to prevent the vehicle jumping from affecting the normal driving of the vehicle, when the vehicle finishes jumping, the tire pressure of the vehicle can be adjusted to the fourth tire pressure threshold to restore the tire pressure during normal driving of the vehicle.

[0096] To effectively assist the vehicle in completing a jump, in some embodiments, step S140 may include adjusting the vehicle's tire pressure to a fourth tire pressure threshold if the vehicle's body motion amplitude satisfies the third jump condition. By monitoring the vehicle's body motion amplitude, it is determined whether the vehicle has landed, and thus whether the jump has ended. This ensures that the tire pressure is adjusted to the fourth tire pressure threshold after the aftershocks of landing have subsided, thereby preventing any impact on the aftershocks' convergence.

[0097] In order to effectively determine whether the vehicle has completed landing, in some embodiments, the third jump condition includes the fluctuation of the body movement amplitude being within a target fluctuation range. The target fluctuation range can be a preset fluctuation range, which can usually be set to a smaller range to ensure that the fluctuation of the body movement amplitude tends to be stable. The body movement amplitude can be monitored by a sensor, such as an IMU (Inertial Measurement Unit). Therefore, the fluctuation of the body movement amplitude can be reflected based on the fluctuation of the sensor data; when the sensor data fluctuation is within the target fluctuation range, the fluctuation of the body movement amplitude is within the target fluctuation range.

[0098] The fourth tire pressure threshold may be a default or preset tire pressure threshold, or a tire pressure threshold determined in real time based on the actual driving state of the vehicle. To improve the accuracy of the fourth tire pressure threshold, in some embodiments, the vehicle jumping method may further include the following steps:

[0099] Step S040: Determine a fourth tire pressure threshold value according to the vehicle's driving status data.

[0100] In some embodiments, the driving state data includes but is not limited to at least one of the following: driving mode data, jump function data, and road condition data. For other descriptions of the vehicle's driving state data, please refer to the description of step S010 above, which will not be repeated here.

[0101] In some embodiments, the above step S040 may include: determining the fourth tire pressure corresponding to the vehicle's driving status data in the fourth mapping data as the fourth tire pressure threshold. The fourth mapping data includes at least one set of corresponding relationships between driving status data and the fourth tire pressure. After obtaining the vehicle's driving status data, the fourth tire pressure corresponding to the vehicle's driving status data can be searched from the fourth mapping data as the fourth tire pressure threshold. By presetting the fourth mapping data, it is helpful to quickly locate the required fourth tire pressure threshold and improve the efficiency of tire pressure adjustment. The fourth mapping data can be obtained in advance based on simulation, or can be obtained based on real vehicle simulation or real vehicle driving, or can be obtained based on empirical data, and this embodiment of the present application does not limit this.

[0102] Below, an example is used to introduce and illustrate the vehicle jumping method provided in an embodiment of the present application.

[0103] First, the target height and how the target mapping data is determined are introduced.

[0104] Based on the tire pressure, tire contact area, vertical load, deformation under the load and other related values, referring to experimental data or using professional tire models, the tire pressure T can be calculated. 1x The stiffness value K of the lower tire x Then use the vehicle simulation model to obtain different stiffness values ​​K x / Different current values ​​I x Under these conditions, the maximum vehicle jump height, H, is calculated. It should be understood that if the impact of different road conditions on jump height / flying distance needs to be expanded, relevant data such as road surface signals and road friction coefficient should be incorporated into the simulation model. Road surface signals refer to the ratio of vehicle speed to the wavelength of road surface roughness when driving on the road.

[0105] Based on real-vehicle simulations, the current and tire pressures were set according to the optimal model obtained from the simulation model, and a vehicle jump test was performed. For a stationary jump, the maximum height h1 was obtained using the height sensor and verified against the simulated height H. For a flying jump, the maximum height h2 was obtained using the height sensor and verified against the simulated height H. It should be understood that at the same initial speed, a higher jump will result in a longer jump distance. Therefore, the maximum jump height is used as the judgment criterion for both stationary and flying jump conditions.

[0106] Finally, a reasonable H value setting is obtained, and it has a certain threshold range, such as accepting an error of ±5mm. If the impact of road conditions needs to be expanded, it is necessary to match the H value under different working conditions according to the above method. Based on this, the maximum jumping height that the vehicle can achieve when jumping under different driving conditions can be obtained, thereby establishing a target mapping relationship. The established target mapping relationship includes at least one set of corresponding relationships between driving state data and target heights, and the driving state data includes at least one of the following: driving mode data, jumping function data, and road condition data. Among them, driving mode data includes but is not limited to: sports mode, off-road mode, comfort mode, track mode, etc.; jumping function data includes but is not limited to: jumping in place, leaping, etc.; road condition data includes but is not limited to: road friction coefficient, road signal, etc., and the road signal is the ratio of the vehicle speed to the wavelength of the road roughness when the vehicle is driving on the road.

[0107] Next, a method for determining the first tire pressure, the first mapping data, the second tire pressure, the second mapping data, the third tire pressure, the third mapping data, the fourth tire pressure, and the fourth mapping data will be introduced.

[0108] For different driving conditions of the vehicle, such as driving mode, jump function, road conditions, etc., the first tire pressure T1 can be set to the tire pressure corresponding to the jump height H (target height) under different driving conditions. Based on this, first mapping data can be established, which includes a correspondence between at least one set of driving condition data and the first tire pressure.

[0109] The second tire pressure, T2, sets the target tire pressure adjustment value when the vehicle reaches the jump height H (target height). This pressure is more suitable for cushioning the vehicle as it reaches the impact point, significantly improving descent comfort. The third tire pressure, T3, sets the target tire pressure adjustment value during the aftershock convergence process after the vehicle passes the impact point, ensuring rapid convergence of shock waves.

[0110] Based on the optimal working condition in the jump height H simulation, set the current value, the first tire pressure T1 and other parameters involved in the jump process, and create a new simulation model for the vehicle's descent process. Then set different tire pressures T2 x After detecting that the jump height reaches H, adjust the tire pressure of the four tires to T2 x; Detect that the jump height decreases for the first time after reaching H, adjust the tire pressure of all four wheels to T3 x The simulation obtains data during the landing process, including but not limited to: the vertical movement amplitude of the vehicle body, aftershock convergence performance, vehicle body z-axis acceleration, etc., in order to evaluate the optimization effect of different tire pressures on landing cushioning performance. The target tire pressure value T2 with the highest cushioning effect / comfort performance is used. x As the second tire pressure T2; use the tire pressure target value T3 with faster oscillation convergence and higher convergence amplitude x Based on this, second mapping data and third mapping data can be established, wherein the second mapping data includes a correspondence between at least one set of driving state data and the second tire pressure, and the third mapping data includes a correspondence between at least one set of driving state data and the third tire pressure.

[0111] The fourth tire pressure, T4, is set to the pressure of all four tires under the current road conditions. The IMU sensor can detect the vehicle's vehicle body motion amplitude. When the oscillation amplitude (i.e., the vehicle body motion amplitude) reaches the normal driving range, the tire pressure is adjusted to T4 to meet the vehicle's normal driving requirements. The IMU sensor threshold during normal driving is derived from normal driving data. Based on this, fourth mapping data can be established, including a correspondence between at least one set of driving status data and the fourth tire pressure.

[0112] See also Figure 3 , Figure 3 This is a flow chart of another vehicle jumping method provided by an embodiment of the present application. Figure 3 As shown, the vehicle jumping method includes the following steps S301 to S315.

[0113] Step S301: The user checks the usage environment and selects the jump function so that the vehicle receives the jump enable command. When the user selects to enable the jump function, such as a standing jump or a flying jump, the user can check the surrounding road conditions and ensure that the environment is safe before selecting the jump function so that the vehicle receives the jump enable command.

[0114] Step S302: In response to the jump enable command, the vehicle determines whether the function entry conditions are met. These conditions include, but are not limited to, at least one of the following: normal tire pressure, normal tire inflation and deflation control signals, normal vehicle suspension module signal transmission and reception, battery level meeting minimum function requirements, and vehicle speed within the required threshold. If the function entry conditions are not met, the process proceeds to step S303. If the function entry conditions are met, the process proceeds to step S304.

[0115] Step S303: The vehicle feedback function is abnormal.

[0116] Step S304: The vehicle enters the jump function.

[0117] Step S305: The vehicle determines a target height threshold H. The vehicle selects a target height corresponding to the current driving state data as the target height threshold H based on the target mapping data.

[0118] Step S306: The vehicle performs active power preparation and calculates the oil flow rate and control current value required for take-off.

[0119] Step S307: The vehicle obtains the current tire pressure.

[0120] Step S308: The vehicle adjusts the current tire pressure to a first tire pressure threshold value T1. The vehicle selects the first tire pressure corresponding to the current driving state data as the first tire pressure threshold value T1 based on the first mapping data.

[0121] Among them, steps S307 to S308 can be executed synchronously with steps S305 to S306.

[0122] Step S309: The vehicle takes off, and the jumping height reaches the target height threshold H at time t1.

[0123] Step S310: The vehicle adjusts the current tire pressure to a second tire pressure threshold value T2 at time t1. The vehicle selects the second tire pressure corresponding to the current driving state data as the second tire pressure threshold value T2 based on the second mapping data.

[0124] Step S311: The vehicle touches the ground at time t2. At time t2, the vehicle completes the landing impact action.

[0125] Step S312: The vehicle's jump height decreases for the first time at time t3. At time t3, the jump height decreases for the first time since time t1, and the landing impact point has passed.

[0126] Step S313: The vehicle adjusts the current tire pressure to a third tire pressure threshold value T3 at time t3. The vehicle selects the third tire pressure corresponding to the current driving state data as the third tire pressure threshold value T3 based on the third mapping data.

[0127] Step S314: The fluctuation of the vehicle body amplitude data at time t4 becomes stable. The data fluctuation of the IMU sensor read by the vehicle at time t4 becomes stable, and the vehicle ends the jump.

[0128] Step S315: The vehicle adjusts the current tire pressure to a fourth tire pressure threshold value T4 at time t4. The vehicle selects the fourth tire pressure corresponding to the current driving state data as the fourth tire pressure threshold value T4 based on the fourth mapping data.

[0129] According to a second aspect of the present application, an embodiment of the present application provides a vehicle jumping system.

[0130] See also Figure 4, Figure 4 FIG2 is a schematic diagram of a vehicle jumping system provided in an embodiment of the present application. The vehicle jumping system can be used to execute the above-mentioned vehicle jumping method.

[0131] like Figure 4 As shown, the vehicle jumping system includes a controller 100. The controller 100 is used to adjust the tire pressure of the vehicle during the vehicle jumping process to assist the vehicle jumping. The controller 100 can be implemented as the vehicle's main ECU (Electronic Control Unit), for example, a domain controller.

[0132] In some embodiments, as Figure 4 As shown, the vehicle jumping system also includes a tire pressure control module 200 connected to the controller 100. The controller 100 is configured to control the tire pressure control module 200 to adjust the vehicle's tire pressure during the vehicle jumping process to assist in the jump. The tire pressure control module 200 is not limited to a fixed tire inflation and deflation structure, but rather represents a wide range of devices and arrangements capable of implementing active tire inflation and deflation functions, which can be summarized as an air source / inflation and deflation valve and related piping structures.

[0133] Based on this, in some embodiments, the controller 100 is used to: generate a tire pressure control signal according to the tire pressure of the vehicle during the vehicle jumping process; send the tire pressure control signal to the tire pressure control module 200 so that the tire pressure control module 200 adjusts the tire pressure of the vehicle. The tire pressure control signal includes but is not limited to the inflation and deflation valve control signal, so that the tire pressure control module 200 can inflate and deflate the tire, thereby adjusting the tire pressure. In order to enable the controller 100 to grasp the tire pressure of the vehicle, in some embodiments, such as Figure 4 As shown, the vehicle jumping system further includes a tire pressure sensor 210 connected to the controller 100. The tire pressure sensor 210 is used to send the tire pressure of the vehicle to the controller 100.

[0134] In some embodiments, as Figure 4 As shown, the vehicle jumping system also includes a suspension control module 300 connected to the controller 100. The controller 100 is configured to control the suspension control module 300 to adjust the height of the vehicle suspension to control vehicle jumping. The suspension control module 300 can be implemented as a controller for the vehicle suspension or can be provided independently of the vehicle suspension. The suspension control module 300 can adjust the height of the vehicle suspension to control vehicle jumping. In this embodiment of the present application, the vehicle suspension can be implemented as an active suspension.

[0135] Based on this, in some embodiments, the controller 100 is configured to: generate a suspension control signal based on the vehicle's height during a vehicle jump; and transmit the suspension control signal to the suspension control module 300, causing the suspension control module 300 to adjust the vehicle's suspension height. Suspension control signals include, but are not limited to, height control signals, damping control signals, stiffness control signals, and active power current control signals. To enable the controller 100 to determine the vehicle's height, in some embodiments, the vehicle jump system further includes a height sensor 310 connected to the controller 100. The height sensor 310 is configured to transmit the vehicle's height to the controller 100.

[0136] In addition, if Figure 4 As shown, the vehicle suspension system may further include an IMU 110, a speed sensor 120, and a function setting module 130. The IMU 110 is used to send data related to the vehicle body motion amplitude to the controller 100, the speed sensor 120 is used to send the vehicle motion speed to the controller 100, and the function setting module 130 is used to send jump enable instructions, jump function selection instructions, etc. to the controller 100. Of course, the vehicle suspension system may further include other sensors or modules, etc., and this embodiment of the application is not limited thereto.

[0137] See also Figure 5 , Figure 5 Schematic diagram of a height data provided by an embodiment of the present application. A height sensor 310 can be installed at the shock absorber position of the vehicle suspension to measure the original height data. The original height data can reflect the length of the shock absorber stretched or compressed. After the original height data is converted by the height calculation formula built into the vehicle suspension controller, it can be output as the distance between the vehicle's wheel arch and the wheel center, that is, the vehicle's jumping height, as shown in FIG. Figure 5 shown.

[0138] See also Figure 6 , Figure 6 Schematic diagram of another vehicle jumping system provided in an embodiment of the present application. Figure 6As shown, the vehicle jumping system is divided into a simulation calculation module 610, a function call module 620, a function detection module 630, and a function execution module 640. The simulation calculation module 610, the function call module 620, and the function detection module 630 can be implemented as internal modules of the controller 100. The function execution module 640 can include the tire pressure control module 200 and the suspension control module 300. The simulation calculation module 610 is used to simulate height thresholds, simulate tire pressures, and calculate oscillation curves based on different driving modes, jumping functions, road conditions, etc., thereby obtaining the first tire pressure T1, the second tire pressure T2, the third tire pressure T3, and the fourth tire pressure T4 under different driving state data. The function call module 620 can obtain the vehicle's current jumping function, such as standing jump, flying jump, or passive jump. The function detection module 630 can detect whether the vehicle meets the function entry conditions, such as performing tire pressure detection, module detection, vehicle speed detection, and battery detection.

[0139] It should be understood that for jumping functions such as standing jumps or leaps, the tire pressure adjustment of the embodiments of the present application can be applied to the jump, touchdown, landing, and jump termination processes. For passive jumps, such as those performed after encountering obstacles or potholes, the tire pressure adjustment of the embodiments of the present application can be applied to the vehicle's descent process, such as touchdown, landing, and jump termination. The vehicle can determine whether it is a passive jump by detecting the stretching speed or stretching length of the shock absorber and comparing it with a preset threshold.
