[0001] The present application relates to the field of vehicle engineering, and in particular to an all-terrain vehicle. Background Art

[0002] An all-terrain vehicle (ATV) is a vehicle that can travel on any terrain, easily maneuvering over terrain difficult for ordinary vehicles. In China, it's commonly known as a beach buggy. Because its structure is very similar to a motorcycle and many of its components are shared, some also call it a "quad." This type of vehicle has multiple uses and is not restricted by road conditions.

[0003] All-terrain vehicles (ATVs) are typically used for outdoor recreation and are often parked on steep slopes, such as in mountains, deserts, swamps, snowfields, and jungles. Failure to park the vehicle promptly outdoors can easily lead to accidents and pose a threat to personal safety. Existing ATV parking systems primarily rely on manual parking brakes, which often fail to adapt to the complex parking environments of ATVs, resulting in the vehicle rolling away and causing safety issues.

[0005] To achieve the above objectives, this application adopts the following technical solutions:

[0006] An all-terrain vehicle comprises a frame, a suspension assembly, a traveling assembly, a braking system and a power system; the suspension assembly is connected to the frame; the traveling assembly is connected to the frame through the suspension assembly; the braking system comprises a brake disc and a brake caliper for clamping the brake disc, and the brake disc is at least partially arranged on the traveling assembly; the power system is connected to the traveling assembly through a transmission; the braking system also comprises a first parking device, a second parking device, a sensor assembly and a parking controller, the first parking device and the second parking device are both connected to the brake caliper for driving the brake caliper to clamp the brake disc, and the first parking device and the second parking device are connected to the brake caliper through the parking The controller transmits signals to the sensor assembly, and the sensor assembly is used to detect vehicle status parameters of the all-terrain vehicle, wherein the vehicle status parameters include at least the current tire pressure. The parking controller determines the target braking force required to achieve parking based on the vehicle status parameters; when the target braking force is less than or equal to a first set threshold, the parking controller controls the brake caliper to perform the parking operation through the first parking device; when the target braking force is greater than the first set threshold, the parking controller controls the brake caliper to perform the parking operation through the second parking device, wherein the maximum braking force of the first parking device is less than the maximum braking force of the second parking device.

[0007] Furthermore, when the target braking force is greater than a first set threshold and less than a second set threshold, the parking controller controls the brake caliper to perform a parking operation through the second parking device; when the target braking force is greater than or equal to the second set threshold, the parking controller controls the brake caliper to perform a parking operation through the first parking device and the second parking device, wherein the second set threshold is greater than the first set threshold.

When at least two vehicle state parameters meet the parking reinforcement conditions, the parking controller controls the brake caliper through the second parking device to perform the parking operation, wherein the parking reinforcement conditions include temperature thresholds, angle thresholds, and tire temperature thresholds corresponding to the ambient temperature, inclination angle, and tire temperature, respectively.

[0009] Furthermore, when at least three vehicle state parameters satisfy the parking reinforcement condition, the parking controller controls the brake caliper to perform a parking operation through the first parking device and the second parking device.

[0010] Furthermore, the parking controller determines a tire pressure increment based on the current tire pressure and a set standard tire pressure threshold, and analyzes corresponding parking reinforcement conditions based on the tire pressure increment to obtain a target braking force.

[0011] Furthermore, the parking reinforcement condition is to meet at least one of the following: ambient temperature is greater than or equal to 40°C, the tilt angle is greater than or equal to 3° or less than or equal to -3°, the tire pressure increase is greater than or equal to 30 kPa, and the tire temperature is greater than 85°C.

[0012] Furthermore, the parking controller includes a communication module, and the parking controller transmits signals with the tire pressure sensor and the tire temperature sensor through the communication module, wherein the communication module includes at least one of a Bluetooth module, a Zigbee module and a WIFI module.

This configuration enables the vehicle to automatically adjust the parking force based on the parking environment, thereby improving parking safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation of the present application will be clearly and completely described below in conjunction with the drawings in the implementation of the present application.

[0026] In the description of this application, it should be understood that 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 technical features indicated. Therefore, features specified as "first" or "second" may explicitly or implicitly include at least one of such features.

[0027] This application provides Figure 1 An all-terrain vehicle 100 is shown, which includes: a frame 11, a suspension assembly 12, a traveling assembly 13, a braking system 14 and a power system 15. The suspension assembly 12 is connected to the frame 11 and the suspension assembly 12 is at least partially arranged at the lower end of the frame 11, and the traveling assembly 13 is connected to the frame 11 through the suspension assembly 12. The braking system 14 is at least partially arranged on the traveling assembly 13, and the all-terrain vehicle 100 achieves vehicle braking through the cooperation of the braking system 14 and the traveling assembly 13. The power system 15 is at least partially arranged on the frame 11, and the power system 15 is transmission-connected to the traveling assembly 13 to provide power to drive the all-terrain vehicle 100 to move. The present application also provides Figure 1 The up-down, left-right, and front-back directions shown are the up-down, left-right, and front-back directions of the all-terrain vehicle 100 .

[0028] Specifically, if Figure 2 As shown, the braking system 14 includes a brake disc 141 and a brake caliper 142 for clamping the brake disc 141. The brake disc 141 is at least partially disposed on the traveling assembly 13. The brake disc 141, also known as the brake disc, is a frictional component on a disc brake that rotates with the wheels as the vehicle moves. When the vehicle brakes, the brake caliper 142 clamps the brake disc 141 to apply friction braking, slowing or stopping the vehicle. The brake caliper 142, also known as the brake caliper, is a component that applies force to the brake disc 141. The hydraulic pressure generated by the master brake cylinder ultimately acts on a piston inside the brake caliper 142. The piston expands, pushing the brake pads toward the brake disc 141. The brake caliper 142 can help the wheels slow down, stop, or maintain a stopped state.

[0029] like Figure 2 and Figure 3As shown, as an implementation, the braking system 14 further includes a first parking device 143, a second parking device 144, a sensor assembly 145, and a parking controller 146. The parking controller 146 is communicatively connected to the first parking device 143 and the second parking device 144, respectively. The first parking device 143 and the second parking device 144 transmit signals to the sensor assembly 145 via the parking controller 146. The first parking device 143 and the second parking device 144 are both connected to the brake caliper 142, which is used to drive the brake caliper 142 to clamp the brake disc 141 to decelerate, stop, or maintain the wheel in a stopped state.

[0030] The first parking device 143 is a hydraulic pump. When the parking brake is applied, the hydraulic pump of the hydraulic pump is activated, increasing the pressure of the hydraulic oil in the hydraulic pipeline of the hydraulic pump. The hydraulic oil pushes the brake caliper 142 into contact with the brake disc 141, achieving parking braking through friction. The second parking device 144 is a caliper motor. When the parking brake is applied, the caliper motor is activated after receiving a signal from the brake system 14, outputting torque. After the torque is decelerated and amplified by the reduction mechanism, it is transmitted to the screw-nut mechanism, which pushes the brake piston to press against the brake disc 141, completing the parking brake. The braking force of the first parking device 143 is less than that of the second parking device 144.

[0031] Preferably, the parking controller 146 includes a communication module 1461 , and the parking controller 146 transmits signals with the sensor assembly 145 via the communication module 1461 , thereby improving communication efficiency and ensuring communication security.

[0032] Optionally, the communication module 1461 can be a Bluetooth module, a Zigbee module or a WIFI module or a combination of any one or at least two minimum functional units with communication functions. This communication method ensures that the effective signal transmission distance is short and the speed is fast, ensures the security of signal transmission, and thus can improve parking safety.

[0033] As an implementation method, the sensor component 145 is communicatively connected to the parking controller 146. The sensor component 145 is used to detect the vehicle state parameters of the all-terrain vehicle 100 and transmit the vehicle state parameters to the parking controller 146, which can provide the prerequisite for the subsequent automatic parking of the all-terrain vehicle 100.

[0034] Furthermore, the sensor assembly 145 includes a temperature sensor 1451, an angle sensor 1452, a tire pressure sensor 1453, and a tire temperature sensor 1454. The temperature sensor 1451 is used to detect the ambient temperature, the angle sensor 1452 is used to detect the inclination angle of the longitudinal direction of the ATV 100 relative to the horizontal plane, the tire pressure sensor 1453 is used to detect the current tire pressure of the ATV 100, and the tire temperature sensor 1454 is used to detect the tire temperature of the ATV 100. Vehicle status parameters include ambient temperature, inclination angle, current tire pressure, and tire temperature. It should be noted that the longitudinal direction of the ATV 100 is parallel to the front-to-back direction of the ATV 100.

[0035] Although this application cites the above-mentioned sensor types, it does not mean that the sensor assembly 145 only includes the above-mentioned sensor types. Any sensor type used to detect factors affecting the braking effect of the vehicle is within the scope of protection required by this application and will not be described in detail here.

[0036] Furthermore, signal transmission between the sensor assembly 145 and the parking controller 146 may be performed via wired communication, or wireless communication via the aforementioned communication module 1461. The method for communicating between the sensor assembly 145 and the parking controller 146 is selected based on the location and installation conditions of the sensor assembly 145 and is not specifically limited herein.

[0037] In an embodiment of the present application, the tire pressure sensor 1453 and the tire temperature sensor 1454 transmit signals to the communication module 1461 of the parking controller 146 via wireless communication to ensure that the parking controller 146 can receive the tire pressure signal and tire temperature signal obtained by the tire pressure sensor 1453 and the tire temperature sensor 1454.

[0038] like Figure 3 As shown, for example, the temperature sensor 1451 generates an ambient temperature signal representing the ambient temperature, and the temperature sensor 1451 sends the ambient temperature signal to the parking controller 146 .

[0039] For example, the angle sensor 1452 generates a tilt angle signal representing a tilt angle, and the angle sensor 1452 sends the tilt angle signal to the parking controller 146 .

[0040] Illustratively, the tire pressure sensor 1453 generates a tire pressure signal representing the current tire pressure, and the tire pressure sensor 1453 sends the tire pressure signal to the parking controller 146 .

[0041] For example, the tire temperature sensor 1454 generates a tire temperature signal representing the temperature of the tire, and the tire temperature sensor 1454 sends the tire temperature signal to the parking controller 146 .

[0042] As an implementation, parking controller 146 receives vehicle state parameters transmitted by sensor assembly 145 and determines the target braking force required to achieve parking based on the vehicle state parameters. Specifically, the vehicle state parameters include the current tire pressure. Parking controller 146 receives a tire pressure signal representing the current tire pressure transmitted by sensor assembly 145. Parking controller 146 determines the tire pressure increment based on the current tire pressure and a set standard tire pressure threshold. The standard tire pressure is the tire pressure at the time the vehicle leaves the factory, and the tire pressure increment is specifically the difference between the current tire pressure and the standard tire pressure. When the current tire pressure is low, the tire's contact patch is reduced, and friction with the ground is also reduced. This may result in insufficient parking braking force, making the vehicle prone to sliding or rolling when parked. Therefore, parking controller 146 determines the target braking force required to achieve parking based on the tire pressure increment. Specifically, when the parking controller 146 determines that the target braking force is less than or equal to the first set threshold, the parking controller 146 controls the brake caliper 142 to perform the parking operation through the first parking device 143; when the parking controller 146 determines that the target braking force is greater than the first set threshold and less than the second set threshold, the parking controller 146 controls the brake caliper 142 to perform the parking operation through the second parking device 144; when the parking controller 146 determines that the target braking force is greater than or equal to the second set threshold, the parking controller 146 controls the brake caliper 142 to perform the parking operation through the first parking device 143 and the second parking device 144.

[0043] As an implementation method, the first set threshold is greater than or equal to 24Kpa and less than or equal to 36Kpa, and the second set threshold is greater than 36Kpa and less than or equal to 54Kpa. Furthermore, the first set threshold is greater than or equal to 27Kpa and less than or equal to 33Kpa, and the second set threshold is greater than or equal to 40.5Kpa and less than or equal to 49.5Kpa. More preferably, the first set threshold is equal to 30Kpa, and the second set threshold is equal to 45Kpa. The above setting enables the all-terrain vehicle 100 to automatically adjust the parking force according to the parking environment and park in different parking methods, thereby reducing the possibility of the vehicle slipping and improving the stability and reliability of the vehicle when parking. Among them, since the increase in tire pressure increment may cause the tire rigidity to increase, reduce the deformation of the tire, thereby reducing the friction and affecting the parking brake force, then it is necessary to increase the parking brake force to ensure parking safety, so the second set threshold is greater than the first set threshold.

[0044] like Figure 4 FIG. 1 is a flow chart of a first parking method of the braking system 14 of the all-terrain vehicle 100 according to an embodiment of the present application, comprising the following steps:

[0045] S101 , the sensor assembly 145 detects the current tire pressure of the ATV 100 and transmits a detection signal representing the current tire pressure to the parking controller 146 .

[0046] The sensor assembly 145 obtains the current tire pressure of the ATV 100 , encapsulates the detection result representing the current tire pressure into a detection signal, and sends the detection signal to the parking controller 146 in a wireless communication manner.

[0047] S102 : The parking controller 146 determines a tire pressure increment according to the current tire pressure and a set standard tire pressure threshold. The parking controller 146 determines a target braking force required to achieve parking according to the tire pressure increment.

[0048] Parking controller 146 receives a detection signal representing the current tire pressure from sensor assembly 145 and sets the vehicle's factory tire pressure as the standard tire pressure. Based on the current tire pressure and the set standard tire pressure threshold, parking controller 146 determines a tire pressure increment, which is the difference between the current tire pressure and the standard tire pressure. Based on the tire pressure increment, parking controller 146 determines a target braking force required to achieve parking, allowing ATV 100 to select an appropriate parking method based on the target braking force.

[0049] S103 , the parking controller 146 determines whether the target braking force is less than or equal to a first set threshold value. If yes, step S104 is executed; if no, step S105 is executed.

[0050] Parking controller 146 determines the relationship between the target braking force and a first set threshold and a second set threshold. The first set threshold is less than the second set threshold. When the target braking force is less than or equal to the first set threshold, the required parking braking force is relatively small, and engaging first parking device 143 is sufficient to ensure safe parking of the vehicle. Parking controller 146 then controls brake caliper 142 via first parking device 143 to perform the parking operation.

[0051] S104 : The first parking device 143 controls the brake caliper 142 to perform a parking operation.

[0052] The first parking device 143 is a hydraulic pumping device, which controls the brake caliper 142 to perform a parking operation to ensure parking safety when the target braking force is less than or equal to a first set threshold.

[0053] S105 , the parking controller 146 determines whether the target braking force is less than a second set threshold value. If yes, step S106 is executed; if no, step S107 is executed.

[0054] The parking controller 146 determines the relationship between the target braking force and a first set threshold and a second set threshold. The first set threshold is less than the second set threshold. If the target braking force is greater than the first set threshold but less than the second set threshold, it indicates that the required parking braking force is relatively large, and the first parking device 143 is insufficient to ensure parking safety. Therefore, the second parking device 144 is required to ensure parking safety. The parking controller 146 then controls the brake caliper 142 via the second parking device 144 to perform the parking operation.

[0055] S106 : The second parking device 144 controls the brake caliper 142 to perform a parking operation in response to the second parking signal.

[0056] The second parking device 144 is a caliper motor, which controls the brake caliper 142 to perform a parking operation to ensure parking safety when the target braking force is greater than a first set threshold and less than a second set threshold.

[0057] S107 , the parking controller 146 controls the brake caliper 142 to perform a parking operation through the first parking device 143 and the second parking device 144 .

[0058] Parking controller 146 determines the relationship between the target braking force and a first set threshold and a second set threshold, where the first set threshold is less than the second set threshold. When the target braking force is greater than or equal to the second set threshold, it indicates that the required parking braking force is relatively large, and that the first parking device 143 or the second parking device 144 alone is insufficient to ensure parking safety. Therefore, both the first parking device 143 and the second parking device 144 are required to ensure parking safety. Parking controller 146 then controls brake caliper 142 via the first parking device 143 and the second parking device 144 to perform the parking operation.

[0059] It should be noted that although the steps in the above process or the flowchart in the accompanying drawings show a logical order, in some cases, the steps shown or described may be performed in an order different from that shown or described here.

[0060] When the all-terrain vehicle 100 is parked in a complex terrain environment such as a mountain, desert, swamp, snow, or jungle, changes in factors such as ambient temperature, tire inclination angle, and tire temperature will affect tire pressure, thereby affecting the friction between the tire and the ground. Therefore, changes in tire pressure reflect changes in ambient temperature, tire inclination angle, and tire temperature to a certain extent. This embodiment detects changes in tire pressure in real time to obtain the target braking force, and sets a threshold for the target braking force to adopt an appropriate parking method, thereby reducing damage to the tire caused by the parking braking force not being consistent with the actual situation, reducing the risk of the vehicle slipping, and greatly improving the parking safety of the vehicle. Therefore, measuring the parking environment based on changes in the vehicle's current tire pressure is a preferred embodiment. This embodiment can more accurately obtain the vehicle's real-time parking situation, allowing the all-terrain vehicle 100 to cope with complex parking environments, making the vehicle safer.

[0061] As an implementation method, the parking controller 146 receives a detection signal transmitted by the sensor component 145, which is representative of at least one vehicle status parameter including ambient temperature, tilt angle, tire pressure increment, and tire temperature (the detection signal recorded in this application includes at least one of the aforementioned ambient temperature signal, tilt angle signal, tire pressure signal, and tire temperature signal). The parking controller 146 analyzes the corresponding parking reinforcement conditions based on the vehicle status parameters to select the corresponding parking mode. The parking reinforcement conditions include a temperature threshold, an angle threshold, a tire temperature threshold, and a tire pressure threshold corresponding to the ambient temperature, tilt angle, tire temperature, and tire pressure increment, respectively.

[0062] Exemplarily, the vehicle state parameters satisfying the parking reinforcement conditions include the following situations: the ambient temperature reaches a temperature threshold, the tilt angle reaches an angle threshold, the tire pressure increment reaches a tire pressure threshold, the tire temperature reaches a tire temperature threshold, etc.

[0063] The parking controller 146 responds to the detection signal when the all-terrain vehicle 100 remains stationary for more than a preset time, and generates a parking signal for controlling the first parking device 143 and / or the second parking device 144 when the vehicle state parameters meet the preset parking reinforcement conditions. The parking controller 146 transmits the parking signal to the first parking device 143 and / or the second parking device 144. The first parking device 143 and / or the second parking device 144 responds to the parking signal to control the brake caliper 142 to perform the parking operation, so as to realize the function of the all-terrain vehicle 100 automatically adjusting the parking force in different ways, thereby improving parking safety.

[0064] Furthermore, the preset parking reinforcement condition is to meet at least one of the following: ambient temperature greater than or equal to 40°C, tilt angle greater than or equal to 3° or less than or equal to -3°, tire pressure increase greater than or equal to 30kPa, and tire temperature greater than 85°C.

[0065] As an implementation, parking controller 146 enters a first operating state when none of the vehicle's state parameters meet the preset parking reinforcement conditions. It should be noted that in this first operating state, parking controller 146 is unable to generate a parking signal for controlling first parking device 143 and / or second parking device 144 in response to detection signals of the vehicle's state parameters. In this state, if ATV 100 remains in its current state or the driver manually activates the parking switch, parking controller 146 receives the switch signal generated by the switch and controls first parking device 143 to perform the parking operation.

[0066] The parking controller 146 is in the second working state when at least one vehicle state parameter meets the preset parking reinforcement condition. The parking controller 146 responds to the detection signal of the vehicle state parameter and generates a parking signal for controlling the first parking device 143 and / or the second parking device 144.

[0067] The power consumption in the first working state is less than that in the second working state, which reduces the power consumption of the entire vehicle, saves electricity, and reduces the frequency of use of the brake caliper 142 , thereby increasing the service life of the brake caliper 142 .

[0068] like Figure 5 FIG. 1 is a flow chart of an implementation method of the braking system 14 of the all-terrain vehicle 100 according to an embodiment of the present application, comprising the following steps:

[0069] S201 , the sensor assembly 145 detects vehicle state parameters and transmits a detection signal of the vehicle state parameters to the parking controller 146 .

[0070] S202 : The parking controller 146 receives a detection signal representing a vehicle state parameter. When the ATV 100 remains stationary for more than a preset time, the parking controller 146 responds to the detection signal.

[0071] S203 : The parking controller 146 analyzes corresponding parking reinforcement conditions according to the vehicle state parameters.

[0072] S204 , when the sensor assembly 145 detects that any vehicle state parameter meets the preset parking reinforcement condition, the parking controller 146 generates a first parking signal, and the first parking device 143 controls the brake caliper 142 to perform a parking operation in response to the first parking signal.

[0073] S205 , when the sensor assembly 145 detects that at least two vehicle state parameters meet the preset parking reinforcement conditions, the parking controller 146 generates a second parking signal, and the second parking device 144 controls the brake caliper 142 to perform a parking operation in response to the second parking signal.

[0074] S206: When the sensor assembly 145 detects that at least three vehicle state parameters meet the preset parking reinforcement conditions, the parking controller 146 generates a third parking signal, and the first parking device 143 and the second parking device 144 control the brake caliper 142 to perform a parking operation in response to the third parking signal.

[0075] It should be noted that although the steps in the above process or the flowchart in the accompanying drawings show a logical order, in some cases, the steps shown or described may be performed in an order different from that shown or described here.

[0076] In the above configuration, the ATV 100 detects vehicle status parameters such as ambient temperature, tilt angle, tire pressure, and tire temperature during parking in real time through the sensor assembly 145. The parking controller 146 compares and analyzes the vehicle status parameters with the preset parking reinforcement conditions and generates corresponding parking signals to control the corresponding parking mechanism to perform the parking operation. This allows the ATV 100 to perform the parking operation more accurately when dealing with complex parking environments, making the vehicle safer.

[0077] Specifically, if Figure 6 FIG. 1 is a flow chart of the second parking method of the present application. When the parking controller 146 detects that any one of the vehicle state parameters of the ambient temperature, the tilt angle, and the tire pressure increment satisfies a preset parking reinforcement condition, the parking controller 146 generates a first parking signal. The first parking device 143 controls the brake caliper 142 to perform a parking operation in response to the first parking signal. The operation specifically includes the following steps:

[0078] S301 : The parking controller 146 receives detection signals representing the ambient temperature, tilt angle, and tire pressure increment of the all-terrain vehicle 100 .

[0079] S302 : When the ATV 100 remains stationary for more than a preset time, the parking controller 146 responds to a detection signal of a vehicle state parameter.

[0080] S303 , when the parking controller 146 determines whether the ambient temperature is greater than or equal to 40° C., if the determination result is yes, the parking controller 146 generates a first parking signal and executes step S306 ; if the determination result is no, executes step S304 .

[0081] S304 , the parking controller 146 determines whether the tire pressure increment is greater than or equal to 30 kPa. If so, the parking controller 146 generates a first parking signal and executes step S306 ; if not, executes step S305 .

[0082] S305. The parking controller 146 determines whether the vehicle tilt angle is greater than or equal to 3° or less than or equal to -3°. If so, the parking controller 146 generates a first parking signal and executes step S306. If not, executes step S307.

[0083] S306 , the hydraulic pump oil device of the first parking device 143 controls the brake caliper 142 to perform a parking operation in response to the first parking signal.

[0084] S307 : The ATV 100 maintains its current state or the driver manually triggers the parking switch, and the parking controller 146 obtains the switch signal generated by the switch to control the first parking device 143 to perform the parking operation.

[0085] It should be noted that although the steps in the above process or the flowchart in the accompanying drawings show a logical order, in some cases, the steps shown or described may be performed in an order different from that shown or described here.

[0086] In this embodiment, a single variable has a relatively small impact on the entire vehicle. It is sufficient to cyclically detect the aforementioned vehicle state and control the hydraulic pump oil of the first parking device 143 to perform automatic parking, thereby ensuring the parking safety of the vehicle.

[0087] It should be noted that when the tire temperature is high, the tire contact patch is small, and the braking effect of the first parking device 144 controlled by the tire temperature to perform the parking maneuver is poor. Therefore, the present application also provides a second parking method, in which the second parking device 144 controls the brake caliper 142 to perform the parking maneuver.

[0088] like Figure 7 FIG. 1 is a flow chart of the third parking method of the present application. When the parking controller 146 detects that any two of the vehicle state parameters of the current ambient temperature, tilt angle, tire pressure increment, and tire temperature meet the preset parking reinforcement conditions, the parking controller 146 generates a second parking signal. In response to the second parking signal, the parking controller 146 controls the brake caliper 142 to perform a parking operation. Specifically, the following steps are included:

[0089] S401 : The parking controller 146 receives detection signals representing the ambient temperature, tilt angle, tire pressure increment, and tire temperature of the all-terrain vehicle 100 .

[0090] S402 : When the ATV 100 remains stationary for more than a preset time, the parking controller 146 responds to a detection signal of a vehicle state parameter.

[0091] S403, the parking controller 146 determines whether the ambient temperature is greater than or equal to 40°C and whether the tire pressure increase is greater than or equal to 30 kPa. If the judgment result is yes, the parking controller 146 generates a second parking signal and executes step S406; if the judgment result is no, executes step S404.

[0092] S404. The parking controller 146 determines whether the ambient temperature is greater than or equal to 40°C and whether the tire temperature is greater than or equal to 85°C. If so, the parking controller 146 generates a second parking signal and executes step S406. If not, execute step S404.

[0093] S405. The parking controller 146 determines whether the ambient temperature is greater than or equal to 40°C and whether the vehicle tilt angle is greater than or equal to 3° or less than or equal to -3°. If the judgment result is yes, the parking controller 146 generates a second parking signal and executes step S406; if the judgment result is no, execute step S404.

[0094] S406 , the caliper motor of the second parking device 144 responds to the second parking signal and controls the brake caliper 142 to perform a parking operation.

[0095] S407 : The ATV 100 maintains its current state or the driver manually triggers the parking switch, and the parking controller 146 obtains the switch signal generated by the switch to control the first parking device 143 to perform the parking operation.

[0096] It should be noted that although the steps in the above process or the flowchart in the accompanying drawings show a logical order, in some cases, the steps shown or described may be performed in an order different from that shown or described here.

[0097] In this embodiment, since the two variables increase the probability of the all-terrain vehicle 100 slipping, the vehicle state parameters are cyclically detected, and the second parking device 144 caliper motor is used to control the parking operation, which improves the parking force safety to a certain extent.

[0098] like Figure 8 FIG. 1 is a flow chart of a fourth parking method of the present application. When the parking controller 146 detects that at least three vehicle state parameters of the current ambient temperature, tilt angle, tire pressure increment, and tire temperature meet preset parking reinforcement conditions, the parking controller 146 generates a third parking signal. The first parking device 143 and the second parking device 144 control the brake caliper 142 to perform a parking operation in response to the third parking signal. The fourth parking method includes the following steps:

[0099] S501 : The parking controller 146 receives detection signals representing the ambient temperature, tilt angle, tire pressure increment, and tire temperature of the all-terrain vehicle 100 .

[0100] S502 : When the ATV 100 remains stationary for more than a preset time, the parking controller 146 responds to a detection signal of a vehicle state parameter.

[0101] S503. When the parking controller 146 determines whether the ambient temperature is greater than or equal to 40°C, whether the tire pressure increment is greater than or equal to 30 kPa, and whether the vehicle tilt angle is greater than or equal to 3° or less than or equal to -3°, if the judgment result is yes, execute step S505; if the judgment result is no, execute step S504.

[0102] S504. The parking controller 146 determines whether the ambient temperature is greater than or equal to 40°C, whether the tire pressure increment is greater than or equal to 30 kPa, and whether the tire temperature is greater than or equal to 85°C. If the judgment result is yes, the parking controller 146 generates a third parking signal and executes step S505; if the judgment result is no, executes step S506.

[0103] S505 , the hydraulic pump oil device of the first parking device 143 and the caliper motor of the second parking device 144 respond to the third parking signal and control the brake caliper 142 to perform a parking operation.

[0104] S506 : The ATV 100 maintains its current state or the driver manually triggers the parking switch, and the parking controller 146 obtains the switch signal generated by the switch to control the first parking device 143 to perform the parking operation.

[0105] It should be noted that although the steps in the above process or the flowchart in the accompanying drawings show a logical order, in some cases, the steps shown or described may be performed in an order different from that shown or described here.

[0106] In this embodiment, since three or more variables have a very high impact on the vehicle's slipping tendency, the vehicle state parameters are detected cyclically. This method of performing parking operations simultaneously can maximize the parking force and greatly improve parking safety.

[0107] It should be noted that in the aforementioned method for executing the braking system 14 of the all-terrain vehicle 100, the illustrated order does not limit the execution steps; in certain circumstances, the illustrated steps can be executed in a different order. For example, when the sensor assembly 145 detects that two vehicle state parameters satisfy a preset parking reinforcement condition, the parking controller 146 generates a second parking signal. Simultaneously, when the parking controller 146 detects that the target braking force is greater than or equal to a second set threshold, the parking controller 146 generates a third parking signal. At this point, the first parking device 143 and the second parking device 144 control the brake caliper 142 to perform a parking operation in response to the third parking signal to ensure vehicle safety. Similar scenarios are not further described here.

[0108] In summary, the all-terrain vehicle 100 provided in the embodiment of the present application can not only ensure automatic parking when the vehicle state parameters meet the preset parking reinforcement conditions, but also allow manual intervention according to specific scenarios or personal habits, greatly improving the parking safety of the vehicle.

[0109] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims appended to this application.
