Description

Technical Field

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

[0002] An all-terrain vehicle is a vehicle that can travel on any terrain and can travel freely on terrain where ordinary vehicles are difficult to maneuver. In the prior art, when an all-terrain vehicle is parked, the user usually switches the gear of the vehicle to the P gear first, and then controls the brake caliper to lock the brake disc through the parking device to achieve the purpose of parking the vehicle.

[0003] When the user switches the vehicle gear to P gear, the brake caliper does not lock the brake disc. If the ATV moves at this time (for example, when the vehicle is parked on a slope, the caliper is not locked to the brake disc before the gear is switched to P gear, and the vehicle will slide down the slope), the wheels will drive the parking gear in the gearbox to rotate, resulting in an increase in the meshing force between the parking gear and the parking rocker arm. When the user switches the P gear to other gears, the meshing force between the parking gear and the parking rocker arm is large, resulting in a large force between the parking gear and the parking rocker arm when the parking gear and the parking rocker arm are separated, resulting in increased wear on the parking gear and the parking rocker arm. Summary of the invention

[0004] In order to solve the deficiencies of the prior art, an object of the present invention is to provide an all-terrain vehicle whose parking action causes less wear on the gear structure in the gearbox.

[0005] To achieve the above object, the present invention adopts the following technical solution:

[0006] An all-terrain vehicle comprises: a frame, a suspension assembly, a travel assembly, a transmission assembly, a braking system, a gearbox assembly and a shifting system. The suspension assembly is connected to the frame, the travel assembly comprises a driving wheel, and the driving wheel is connected to the frame through the suspension assembly. The transmission assembly comprises a half shaft that is transmission-connected to the driving wheel; the braking system comprises a parking controller and a brake, and the parking controller locks the driving wheel through the brake. The gearbox assembly comprises a gear assembly, and the gear assembly comprises a parking rocker arm and a parking gear, and the parking gear is connected to the half shaft. The shifting system is connected to the gearbox assembly, and the shifting system comprises a gear position adjustment device.

[0007] Furthermore, the transmission assembly includes a transmission controller and an actuator. The transmission controller can generate a parking execution signal when the gear adjustment device is switched to the parking gear, and the parking controller controls the brake to lock the driving wheel in response to the parking execution signal; after the brake locks the driving wheel, the parking controller generates a parking status signal, and the transmission controller controls the actuator to work in response to the parking status signal, and the actuator drives the parking rock arm to engage with the parking gear to limit the rotation of the driving wheel.

[0008] Furthermore, the gear shifting system also includes a gear controller, which is respectively connected to the gear adjustment device and the transmission controller. When the gear adjustment device is switched to the parking gear, the gear controller generates a gear switching signal, the transmission controller generates a parking execution signal in response to the gear switching signal, and the parking controller controls the brake to lock the drive wheel in response to the parking execution signal.

[0009] Furthermore, the all-terrain vehicle also includes a vehicle speed detection module, which is used to detect the current vehicle speed of the all-terrain vehicle. When the gear controller generates a gear switching signal, if the current vehicle speed is less than or equal to a preset vehicle speed, the transmission controller generates a parking execution signal in response to the gear switching signal, and the parking controller controls the brake to lock the drive wheel in response to the parking execution signal.

[0010] Furthermore, the all-terrain vehicle also includes a vehicle controller, which is electrically connected to the gear controller and the transmission controller respectively. The vehicle controller is used to obtain a gear switching signal. The braking system also includes a brake pedal connected to the vehicle controller. When the brake pedal is stepped on, if the current vehicle speed is less than or equal to a preset vehicle speed, the vehicle controller transmits the gear switching signal to the transmission controller, so that the transmission controller generates a parking execution signal in response to the gear switching signal.

[0011] Furthermore, the all-terrain vehicle includes a first power module, which is used to supply power to the parking controller and the transmission controller. When the all-terrain vehicle is powered off, if the current vehicle speed is less than or equal to the preset vehicle speed, the transmission controller generates a parking execution signal, and the parking controller controls the brake to lock the driving wheel in response to the parking execution signal. After the brake locks the driving wheel, the parking controller generates a parking state signal, and the transmission controller controls the actuator to work in response to the parking state signal, and the actuator drives the parking rocker arm to engage with the parking gear to limit the rotation of the driving wheel.

[0012] Furthermore, the all-terrain vehicle includes a vehicle controller and a second power module, the second power module is used to power the all-terrain vehicle, when the all-terrain vehicle is powered off, the second power module is powered off so that the vehicle controller generates a power-off signal, the transmission controller generates a parking execution signal in response to the power-off signal, and the parking controller controls the brake to lock the drive wheel in response to the parking execution signal.

[0013] Furthermore, the vehicle controller is also electrically connected to the first power module, and the vehicle controller is used to detect the current state of the first power module. After the vehicle controller generates a power-off signal, if the vehicle controller detects that the first power module is in a working state, the vehicle controller transmits the power-off signal to the transmission controller, so that the transmission controller generates a parking execution signal in response to the power-off signal, and the parking controller controls the brake to lock the drive wheel in response to the parking execution signal.

[0014] Furthermore, the all-terrain vehicle also includes an instrument panel, which is electrically connected to the vehicle controller. After the vehicle controller generates a power-off signal, if the vehicle controller detects that the first power module is in a fault state, the vehicle controller controls the instrument panel to perform a corresponding display.

[0015] Further, after the transmission controller generates a parking execution signal and sends the parking execution signal to the parking controller, if the transmission controller does not receive a parking status signal within a preset time, the transmission controller controls the all-terrain vehicle to perform a corresponding warning action.

[0016] Furthermore, the actuator is a motor, and the transmission controller drives the parking rock arm to rotate through the actuator so that the parking rock arm is engaged with the parking gear.

[0017] The all-terrain vehicle is provided with a transmission controller and a parking controller. When the gear of the all-terrain vehicle is switched to the parking gear, the brake is first controlled by the parking controller to limit the rotation of the driving wheel, and then the transmission controller controls the all-terrain vehicle to switch to the parking gear, so as to avoid the driving wheel from rotating, resulting in a large meshing force between the parking rocker arm and the parking gear, and the gear adjustment device is difficult to disengage from the parking gear, thereby reducing the difficulty of the gear adjustment device disengaging from the parking gear, and at the same time reducing the wear of the parking rocker arm and the parking gear, and extending the service life of the parking rocker arm and the parking gear.

[0029] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the specific implementation modes of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the implementation modes of the present invention.

[0030] like Figure 1 As shown, the present application provides an all-terrain vehicle 100, which includes a frame 11, a suspension assembly 12, a travel assembly 13, and a transmission assembly 14. The frame 11 serves as the basic framework of the all-terrain vehicle 100, and the suspension assembly 12 is connected to the frame 11. The travel assembly 13 includes a driving wheel 131, which is connected to the frame 11 through the suspension assembly 12, and the driving wheel 131 is connected to the power source of the all-terrain vehicle 100 (when the all-terrain vehicle 100 is an electric drive vehicle, the power source is the driving motor of the all-terrain vehicle 100; when the all-terrain vehicle 100 is a fuel drive vehicle, the power source is the engine of the all-terrain vehicle 100) through the transmission assembly 14. The transmission assembly 14 includes a half shaft 141, which is connected to the driving wheel 131 through transmission, and the half shaft 141 drives the driving wheel 131 to rotate to drive the all-terrain vehicle 100.

[0031] like Figure 1 and Figure 2 As shown, specifically, the all-terrain vehicle 100 further includes a braking system 15, a gearbox assembly 16 and a gear shifting system 17. The braking system 15 includes a parking controller 151 and a brake 152. The parking controller 151 is electrically connected to the brake 152. The parking controller 151 locks the driving wheel 131 through the brake 152 to limit the rotation of the driving wheel 131. The brake 152 at least includes a brake caliper and a brake disc. The brake disc is connected to the driving wheel 131. The brake caliper locks the brake disc to limit the rotation of the driving wheel 131, thereby preventing the vehicle from sliding down a slope after parking.

[0032] like Figure 2 and Figure 3As shown, the gearbox assembly 16 includes a gear assembly 161, and the gear assembly 161 includes a parking rocker arm 1611 and a parking gear 1612 that can mesh with each other. The parking gear 1612 is connected to the half shaft 141. When the parking rocker arm 1611 is meshed with the parking gear 1612, the parking rocker arm 1611 can limit the rotation of the half shaft 141 by limiting the rotation of the parking gear 1612, thereby limiting the rotation of the driving wheel 131. The gear shift system 17 is connected to the gearbox assembly 16, and the gear shift system 17 includes a gear adjustment device 171. The user switches the gear of the all-terrain vehicle 100 by operating the gear adjustment device 171.

[0033] like Figure 3 As shown, specifically, the transmission assembly 16 further includes a transmission controller 162 and an actuator 163, wherein the transmission controller 162 is electrically connected to the parking controller 151, and the transmission controller 162 is also connected to the gear adjustment device 171, and the actuator 163 is connected to the parking rocker arm 1611, wherein the actuator 163 is a motor. When the gear adjustment device 171 is switched to the parking gear or the all-terrain vehicle 100 is powered off, the transmission controller 162 can generate a parking execution signal, and the transmission controller 162 transmits the parking execution signal to the parking controller 151, and the parking controller 151 controls the brake 152 to lock the driving wheel 131 in response to the parking execution signal to limit the rotation of the driving wheel 131, thereby achieving parking of the all-terrain vehicle 100.

[0034] Furthermore, after the brake 152 locks the driving wheel 131, the parking controller 151 generates a parking status signal, and the parking controller 151 transmits the parking status signal to the transmission controller 162. The transmission controller 162 controls the actuator 163 to operate in response to the parking status signal, that is, the actuator 163 drives the parking rocker arm 1611 to rotate so that the parking rocker arm 1611 engages with the parking gear 1612, thereby limiting the rotation of the driving wheel 131, so that the all-terrain vehicle 100 is in the parking gear (the gear adjustment device 171 is in the P gear). In the embodiment of the present application, when the gear of the all-terrain vehicle 100 is switched to the parking gear, the parking controller 151 first controls the brake 152 to limit the rotation of the driving wheel 131, and then switches the gear of the all-terrain vehicle 100 to the parking gear, thereby preventing the driving wheel 131 from rotating, resulting in a large meshing force between the parking rocker arm 1611 and the parking gear 1612, and making it difficult for the gear adjustment device 171 to disengage from the parking gear. Through the above arrangement, the difficulty of the gear adjustment device 171 disengaging from the parking gear is reduced, and the wear of the parking rocker arm 1611 and the parking gear 1612 is reduced, and the service life of the parking rocker arm 1611 and the parking gear 1612 is extended.

[0035] It should be noted that a preset time is set in the transmission controller 162. After the transmission controller 162 generates a parking execution signal, the transmission controller 162 transmits the parking execution signal to the parking controller 151. If the transmission does not receive the parking state signal transmitted by the parking controller 151 within the preset time, the transmission controller 162 controls the all-terrain vehicle 100 to perform a corresponding alarm action to remind the user that the parking controller 151 or the brake 152 is faulty, wherein the alarm action is to display the alarm light. Optionally, the alarm action can also be to output an alarm sound. The alarm actions that can achieve the above functions are all within the protection scope required by this application and are not described in detail here. It can be understood that the user can determine whether the current parking controller 151 or the brake 152 is in a faulty state by checking the alarm action, and then the user can promptly repair the controller or the brake 152 when the parking controller 151 or the brake 152 is in a faulty state. Through the above setting, the maintainability of the parking controller 151 and the brake 152 is improved.

[0036] Exemplarily, the preset time is set to 4 seconds. If the transmission does not receive the parking status signal transmitted by the parking controller 151 within 4 seconds, the transmission controller 162 controls the ATV 100 to perform the aforementioned warning action.

[0037] like Figure 4 As shown, the ATV 100 further includes a first power module 18, which is electrically connected to the parking controller 151 and the transmission controller 162. When the ATV 100 performs the second braking mode, the first power module 18 is used to provide energy for the parking controller 151 and the transmission controller 162 to work, thereby preventing the transmission controller 162 and the parking controller 151 from being in a power-off state after the ATV 100 is powered off, thereby improving the use stability of the transmission controller 162 and the parking controller 151. The first power module 18 is a battery or other energy source capable of driving the electrical components of the ATV 100.

[0038] like Figure 2As shown, as an implementation method, the gear shift system 17 includes, in addition to the gear adjustment device 171, a gear controller 172, and the gear controller 172 is connected to the gear adjustment device 171. The gear controller 172 is also electrically connected to the transmission controller 162. When the gear adjustment device 171 is switched to the parking gear, the user manipulates the gear adjustment device 171 to switch the gear adjustment device 171 to the parking gear, so that the gear controller 172 generates a gear switching signal, and the gear controller 172 transmits the gear switching signal to the transmission controller 162, and then the transmission controller 162 generates a parking execution signal in response to the gear switching signal, and the transmission controller 162 transmits the parking execution signal to the parking controller 151, so that the parking controller 151 controls the brake 152 to lock the drive wheel 131 in response to the parking execution signal to limit the movement of the all-terrain vehicle 100. The above arrangement can prevent the driving wheel 131 from rotating to drive the parking gear 1612 to rotate when the gear of the all-terrain vehicle 100 is in the parking gear, thereby preventing the meshing force between the parking rocker arm 1611 and the parking gear 1612 from being large, and preventing the gear adjustment device 171 from being difficult to disengage from the parking gear. Through the above arrangement, the difficulty of the gear adjustment device 171 disengaging from the parking gear is reduced, and the wear of the parking rocker arm 1611 and the parking gear 1612 is reduced, and the service life of the parking rocker arm 1611 and the parking gear 1612 is extended.

[0039] like Figure 5 As shown, specifically, the all-terrain vehicle 100 further includes a vehicle controller 19, which is electrically connected to the gear controller 172. The vehicle controller 19 is also electrically connected to the transmission controller 162, and the vehicle controller 19 is used to obtain the gear switching signal output by the gear controller 172. The braking system 15 further includes a brake pedal 153, which is connected to the vehicle controller 19. When the vehicle controller 19 obtains the gear switching signal output by the gear controller 172, if the brake pedal 153 is stepped on, the vehicle controller 19 outputs the gear switching signal to the transmission controller 162, so that the transmission controller 162 outputs a parking execution signal to the parking controller 151 in response to the gear switching signal, and then the parking controller 151 can control the brake 152 to lock the driving wheel 131 in response to the parking execution signal. It is understandable that during the driving process of the all-terrain vehicle 100, if the user accidentally touches the gear adjustment device 171 to switch the gear adjustment device 171 to the parking gear, the above arrangement can prevent the vehicle controller 19 from directly outputting the gear switching signal to the transmission controller 162 to cause the brake 152 to reduce the rotation speed of the driving wheel 131, thereby interfering with the user's normal driving. Through the above arrangement, the user's driving experience is improved.

[0040] like Figure 6As shown, as an implementation, the ATV 100 further includes a second power module 21, which is electrically connected to the vehicle controller 19, and is used to supply power to the ATV 100, wherein the second power module 21 is a storage battery or a power battery, etc. When the ATV 100 is powered off, the second power module 21 is powered off. When the vehicle controller 19 detects that the second power module 21 is powered off, the vehicle controller 19 generates a power-off signal, and the vehicle controller 19 transmits the power-off signal to the transmission controller 162. The transmission controller 162 generates a parking execution signal in response to the power-off signal, and the transmission controller 162 transmits the parking execution signal to the parking controller 151. The parking controller 151 controls the brake 152 to lock the driving wheel 131 in response to the parking execution signal. After the brake 152 locks the driving wheel 131, the parking controller 151 generates a parking state signal, and the parking controller 151 transmits the parking state signal to the transmission controller 162. The transmission controller 162 controls the actuator 163 to work in response to the parking state signal so that the ATV 100 is in the parking gear. It can be understood that after the user turns the ignition switch of the ATV 100 to the lock gear, the parking controller 151 can automatically control the brake 152 to lock the driving wheel 131, and the transmission controller 162 automatically controls the actuator 163 to work so that the ATV 100 is in the parking gear. Through the above settings, the user does not need to operate the gear adjustment device 171, and the ATV 100 can lock the driving wheel 131 and switch itself to the parking gear, thereby reducing the user's operation steps and improving the human-computer interaction experience.

[0041] It should be noted that the first power module 18 is an independent energy source. After the second power module 21 is powered off, the first power module 18 can provide working energy for control components such as the transmission controller 162, the parking controller 151, and the gear controller 172, so that the all-terrain vehicle 100 can still implement the aforementioned parking process after power is cut off.

[0042] like Figure 7As shown, as an implementation method, the vehicle controller 19 is also electrically connected to the first power module 18, and the vehicle controller 19 is used to detect the current state of the first power module 18. After the vehicle controller 19 generates a power-off signal, if the vehicle controller 19 detects that the first power module 18 is in a working state, the vehicle controller 19 transmits the power-off signal to the transmission controller 162, and the transmission controller 162 generates a parking execution signal in response to the power-off signal. The transmission controller 162 transmits the parking execution signal to the parking controller 151, and the parking controller 151 controls the brake 152 to lock the drive wheel 131 in response to the parking execution signal. Since the first power module 18 is used to provide energy for the transmission controller 162 and the parking controller 151, after the vehicle controller 19 generates a power-off signal, the vehicle controller 19 detects the current state of the first power module 18 to ensure that the first power module 18 can provide energy for the transmission controller 162 and the parking controller 151, thereby improving the reliability of the transmission controller 162 and the parking controller 151 when the transmission controller 162 and the parking controller 151 perform corresponding actions.

[0043] like Figure 7 As shown, the ATV 100 further includes a dashboard 22, which is electrically connected to the vehicle controller 19. The dashboard 22 is disposed in the cockpit of the ATV 100. The user can obtain the status information of the ATV 100 by observing the dashboard 22, wherein the status information of the ATV 100 includes the current speed and mileage of the ATV 100. After the vehicle controller 19 generates a power-off signal, if the vehicle controller 19 detects that the first power module 18 is in a fault state, the vehicle controller 19 generates a fault signal, and the vehicle controller 19 transmits the fault signal to the dashboard 22, and the dashboard 22 performs a corresponding display in response to the fault signal.

[0044] Specifically, a light emitting unit is provided on the instrument panel 22. After the instrument panel 22 receives the fault signal transmitted by the vehicle controller 19, the instrument panel 22 controls the light emitting unit to output corresponding fault light in response to the fault signal, so that the user can obtain the fault information of the first power module 18 in time, and then the user can timely repair the first power module 18. Through the above arrangement, the maintainability of the first power module 18 is improved.

[0045] Optionally, a sound unit can also be provided on the instrument panel 22. After the instrument panel 22 receives the fault signal transmitted by the vehicle controller 19, the instrument panel 22 controls the sound unit to output a corresponding fault sound in response to the fault signal. The sound unit is a buzzer or an audio playback device. Devices that can achieve the above functions are within the protection scope required by this application and are not limited here.

[0046] like Figure 8As shown, as an implementation, the ATV 100 further includes a vehicle speed detection module 23, which is electrically connected to the vehicle controller 19, and is used to detect the current vehicle speed of the ATV 100. The vehicle speed detection module 23 is also used to send the current vehicle speed of the ATV 100 to the vehicle controller 19. The vehicle controller 19 is provided with a preset vehicle speed. If the current vehicle speed of the ATV 100 is less than or equal to the preset vehicle speed, the vehicle controller 19 transmits a power-off signal to the gearbox controller 162, and the gearbox controller 162 generates a parking execution signal in response to the power-off signal. The gearbox controller 162 transmits the parking execution signal to the parking controller 151, and the parking controller 151 controls the brake 152 to lock the driving wheel 131 in response to the parking execution signal. The vehicle speed detection module 23 is a Hall sensor, and the rotation speed of the travel component is detected by the Hall sensor to obtain the current vehicle speed of the ATV 100. When the current speed of the all-terrain vehicle 100 is relatively high, if the parking controller 151 controls the brake 152 to lock the driving wheel 131, the driving wheel 131 may be locked, thereby causing the all-terrain vehicle 100 to slide or even roll over. The above arrangement improves the safety of the all-terrain vehicle 100 during driving.

[0047] Furthermore, when the brake pedal 153 is stepped on, if the current speed of the ATV 100 is less than or equal to the preset speed, the vehicle controller 19 transmits the gear switching signal to the transmission controller 162, and the transmission controller 162 generates a parking execution signal in response to the gear switching signal. The transmission controller 162 transmits the parking execution signal to the parking controller 151, and the parking controller 151 controls the brake 152 to lock the driving wheel 131 in response to the parking execution signal. Since the transmission controller 162 is provided with a preset time, if the current speed of the ATV 100 is relatively high, the time required for the brake 152 to lock the driving wheel 131 is also relatively long, resulting in a relatively long interval between the transmission controller 162 outputting the parking execution signal and the transmission controller 162 receiving the parking state signal, and thus the transmission controller 162 has a relatively high false alarm rate. Through the above-mentioned setting, the false alarm rate of the transmission controller 162 is reduced.

[0048] In order to clearly illustrate the technical solution of the present application, the implementation mode of the present application also provides the following Fig. 9 The flowchart of the all-terrain vehicle 100 performing parking is shown, and the flowchart includes the following steps:

[0049] S1, start;

[0050] S2, determining whether the ATV 100 is in the parking gear, if so, repeating step S2, if not, executing step S3;

[0051] S3, determining whether the all-terrain vehicle 100 is in a power-off state, if not, executing step S4, if yes, executing step S5;

[0052] S4, the all-terrain vehicle 100 executes a first parking process;

[0053] S5, the all-terrain vehicle 100 executes the second parking process;

[0054] S6. End.

[0055] 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 executed in an order different from that shown or described here.

[0056] like Fig.10 As shown, the first parking process of the all-terrain vehicle 100 includes the following steps:

[0057] S41, determining whether the gear adjustment device 171 is switched to the parking gear, if so, executing step S42, if not, repeating step S41;

[0058] The vehicle controller 19 detects whether the gear adjustment device 171 is switched to the parking gear. If so, step S42 is executed. If not, the vehicle controller 19 repeatedly detects whether the gear adjustment device 171 is switched to the parking gear.

[0059] S42, determining whether the brake pedal 153 is depressed, if so, executing step S43, if not, repeating step S42;

[0060] The vehicle controller 19 detects whether the brake pedal 153 is depressed. If so, step S43 is executed. If not, the vehicle controller 19 repeats the detection of whether the brake pedal 153 is depressed.

[0061] S43, determining whether the current vehicle speed is less than or equal to a preset vehicle speed, if so, executing step S44, if not, repeating step S43;

[0062] The vehicle speed detection module 23 detects the current vehicle speed of the all-terrain vehicle 100 and encapsulates it into a speed signal for transmission to the vehicle controller 19. If the vehicle controller 19 determines that the current vehicle speed is less than or equal to the preset speed, step S44 is executed. If the vehicle controller 19 determines that the current vehicle speed is greater than the preset speed, the vehicle speed detection module 23 repeatedly detects the current vehicle speed of the all-terrain vehicle 100.

[0063] S44, generating a parking execution signal to control the brake 152 to lock the driving wheel 131, generating a parking state signal and transmitting it to the transmission controller 162;

[0064] The vehicle controller 19 transmits the gear switching signal to the transmission controller 162 , and the transmission controller 162 generates a parking execution signal in response to the gear switching signal. The parking controller 151 controls the brake 152 to lock the drive wheel 131 in response to the parking execution signal, and then the parking controller 151 generates a parking status signal and transmits it to the transmission controller 162 .

[0065] S45, determining whether the time interval between the parking execution signal and the parking status signal is greater than a preset time, if so, executing step S46, if not, executing step S47;

[0066] S46, the instrument panel 22 performs corresponding display;

[0067] The instrument panel 22 displays the fault information.

[0068] S47 , controlling the parking rocker arm 1611 to engage with the parking gear 1612 .

[0069] The transmission controller 162 controls the actuator 163 to drive the parking rocker arm 1611 to engage with the parking gear 1612 in response to the parking state signal.

[0070] 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 executed in an order different from that shown or described here.

[0071] like Fig.11 As shown, the second parking process performed by the all-terrain vehicle 100 includes the following steps:

[0072] S51, detecting whether the first power module 18 is in a fault state, if so, executing step S52, if not, executing step S53;

[0073] The vehicle controller 19 detects whether the first power module 18 is in a faulty state. If the first power module 18 is in a faulty state, step S52 is executed; if the first power module 18 is not in a faulty state, step S53 is executed.

[0074] S52, the instrument panel 22 performs corresponding display;

[0075] The instrument panel 22 displays the fault information.

[0076] S53, determining whether the current vehicle speed is less than or equal to a preset vehicle speed, if so, executing step S54, if not, repeating step S53;

[0077] The vehicle speed detection module 23 detects the current vehicle speed of the all-terrain vehicle 100 and encapsulates it into a speed signal for transmission to the vehicle controller 19. If the vehicle controller 19 determines that the current vehicle speed is less than or equal to the preset speed, step S54 is executed. If the vehicle controller 19 determines that the current vehicle speed is greater than the preset speed, the vehicle speed detection module 23 repeatedly detects the current vehicle speed of the all-terrain vehicle 100.

[0078] S54, generating a parking execution signal to control the brake 152 to lock the driving wheel 131, generating a parking state signal and transmitting it to the transmission controller 162;

[0079] The vehicle controller 19 transmits the gear switching signal to the transmission controller 162 , and the transmission controller 162 generates a parking execution signal in response to the gear switching signal. The parking controller 151 controls the brake 152 to lock the drive wheel 131 in response to the parking execution signal, and then the parking controller 151 generates a parking status signal and transmits it to the transmission controller 162 .

[0080] S55, determining whether the time interval between the parking execution signal and the parking status signal is greater than a preset time, if so, executing step S56, if not, executing step S57;

[0081] S56, the instrument panel 22 performs corresponding display;

[0082] The instrument panel 22 displays the fault information.

[0083] S57 , controlling the parking rocker arm 1611 to engage with the parking gear 1612 .

[0084] The transmission controller 162 controls the actuator 163 to drive the parking rocker arm 1611 to engage with the parking gear 1612 in response to the parking state signal.

[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 executed in an order different from that shown or described here.

[0086] In summary, when the gear of the all-terrain vehicle 100 is switched to the parking gear, the brake 152 is first controlled by the parking controller 151 to limit the rotation of the driving wheel 131, and then the all-terrain vehicle 100 is switched to the parking gear, so as to avoid the rotation of the driving wheel 131, which causes a large meshing force between the parking rocker arm 1611 and the parking gear 1612, and the gear adjustment device 171 is difficult to disengage from the parking gear. Through the above-mentioned setting, the difficulty of the gear adjustment device 171 disengaging from the parking gear is reduced, and the wear of the parking rocker arm 1611 and the parking gear 1612 is reduced, and the service life of the parking rocker arm 1611 and the parking gear 1612 is extended. In addition, the vehicle controller 19 and the gearbox controller 162 can also control the all-terrain vehicle 100 to perform an alarm action, so that the user can obtain the fault information of the parking controller 151, the brake 152 and the first power module 18 in time, thereby improving the maintainability of the parking controller 151, the brake 152 and the first power module 18.
