[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be fully described below in combination with the drawings in the embodiments of the present invention through specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work fall within the protection scope of the present invention.

[0028] Embodiment 1

[0029] Figure 1 is a flow chart of a control method for a vehicle power take-off provided in the first embodiment of the present invention, with reference to Figure 1 As shown, this embodiment can be applied to vehicles such as electric vehicles or fuel vehicles. The method can be executed by a control device for a vehicle power take-off in an embodiment of the present invention, wherein the device can be implemented by software and / or hardware. The method specifically includes the following steps:

[0030] S110, determining whether the power take-off of the vehicle enters the working mode, if the power take-off enters the working mode, executing S120; if the power take-off does not enter the working mode, executing S150;

[0031] Among them, the power take-off (PTO) is one or more sets of speed gears, also known as a power output device, which is generally composed of a gear box, a clutch, etc. The power take-off is arranged on the vehicle. If the power take-off is put into use, the clutch of the power take-off can be controlled to combine with the drive shaft of the vehicle, so as to transmit power to an external working device connected to the power take-off, such as a lifting pump, etc., to realize other functions of the vehicle. The embodiment of the present invention does not limit the type of specific external working device. In other words, for some vehicles including a power take-off, in addition to having normal formal functions, it can also have other functions. For example, when the vehicle is a mixer truck, the power take-off can be controlled to stir the contents of the mixing tank; for example, when the vehicle is a cleaning vehicle, the power take-off can be controlled to clean the road surface, etc.

[0032] Furthermore, for a vehicle including a power take-off, the power take-off is not controlled to work in all states of the vehicle. For example, at a higher driving speed, in order to ensure the safe driving of the vehicle, the power take-off does not enter the working mode. In addition, the factors for the power take-off not entering the working mode may also be insufficient power of the vehicle (if the vehicle is a fuel vehicle, the fuel is insufficient; or if the vehicle is an electric vehicle, the power is insufficient), or when the vehicle does not need to realize other functions at present, etc. The embodiments of the present invention do not give examples of the reasons for not entering the working mode.

[0033] Specifically, when the power take-off needs to be put into use, it is necessary to determine whether the power take-off has entered the working mode. If the power take-off has entered the working mode, the vehicle can realize other functions brought by the power take-off, enriching the use scenarios of the vehicle; if the power take-off has not entered the working mode, the vehicle can only realize the normal driving function. Furthermore, the working mode of the power take-off includes driving mode or parking mode. The driving mode can be understood as controlling the power take-off to enter the working state when the vehicle is driving at a low speed. In addition to the function of driving at a low speed, the vehicle also has other functions brought by the power take-off; the parking mode can be understood as controlling the power take-off to enter the working state when the vehicle is stationary, and the vehicle has other functions brought by the power take-off.

[0034] S120, controlling the clutch of the power take-off to engage with the drive shaft of the vehicle.

[0035] Specifically, if the power take-off enters the working mode, whether it is the driving mode or the parking mode, it is necessary to control the clutch of the power take-off to combine with the drive shaft of the vehicle, so as to obtain power and provide it to the external working device connected to the power take-off. In this regard, it can be understood that the power obtained by the power take-off is provided by the drive shaft of the vehicle.

[0036] S130: Determine whether the driving speed exceeds the calibrated speed of the power take-off.

[0037] Among them, the power take-off enters the working mode. When the clutch of the power take-off is combined with the drive shaft, or when the clutch of the power take-off is enabled, the gear set in the gearbox of the power take-off works, and different speed ratio conversions can be achieved through different numbers of teeth, thereby achieving different speeds of the power take-off. At different speeds, the power take-off can provide different degrees of power to the external working device and achieve different working intensities.

[0038] Furthermore, the speed adjustment of the power take-off can be adjusted in combination with the driving speed of the vehicle, so as to achieve convenient speed adjustment of the power take-off and integrated design of the vehicle. Among them, the vehicle has a cruise control button, which is used to turn on, adjust and turn off the cruise control function of the vehicle. Cruise control is a car driving assistance system that allows the car to drive automatically at a set speed without the driver having to operate the throttle. When the car enters the cruising state, the controller will continuously adjust the fuel supply according to the road conditions and the driving resistance of the car to keep the speed stable. Generally, the cruise control button is not used when the vehicle is driving at a low speed. In order to achieve the integrated setting of the vehicle, the speed adjustment of the power take-off can be combined with the cruise control button.

[0039] Specifically, first obtain the vehicle's driving speed, and determine the magnitude of the driving speed and the calibrated speed of the power take-off. The calibrated speed of the power take-off can be understood as a pre-set threshold. If the vehicle's driving speed is less than or equal to the threshold, it proves that the current vehicle speed is low, and the speed of the power take-off can be adjusted using the cruise control button without affecting the vehicle's driving; if the vehicle's driving speed is greater than the threshold, using the cruise control button to adjust the speed of the power take-off at this speed may interfere with the vehicle's driving, etc., affecting the safety of the vehicle's driving, so the cruise control button is different from adjusting the speed of the power take-off. Therefore, by determining the magnitude relationship between the driving speed and the calibrated speed of the power take-off, it is determined whether the cruise control button is used to adjust the speed of the power take-off.

[0040] S140, the cruise control button for controlling the vehicle is used to adjust the rotation speed of the power take-off.

[0041] Specifically, if the vehicle's driving speed does not exceed the calibrated speed of the power take-off, then when the current cruise control button is used to adjust the speed of the power take-off, it will not interfere with or affect other functions of the vehicle. Adjusting the speed of the power take-off by using the existing buttons can reflect the integrated design of the vehicle without the need to add redundant buttons. Furthermore, if the vehicle's driving speed exceeds the calibrated speed of the power take-off, it proves that the current vehicle speed is high, or that it is not conducive to turning on the working mode of the power take-off at this speed, and the power take-off will not start the working mode. Therefore, there will be no situation where the speed of the power take-off cannot be adjusted when the driving speed exceeds the calibrated speed of the power take-off. Therefore, it is further demonstrated that using the existing cruise control button to adjust the speed of the power take-off is simple and reliable.

[0042] S150: Control the clutch of the power take-off to be disengaged from the drive shaft of the vehicle.

[0043] Specifically, if the power take-off does not enter the working mode, the clutch of the power take-off is kept in a non-engaged state with the vehicle's drive shaft. Furthermore, if the power take-off is originally in the working mode, whether the power take-off is originally in the driving mode or the parking mode, when it is determined that the current power take-off does not need to enter the working mode again, it is necessary to control the clutch of the power take-off and the vehicle's drive shaft to adjust from the engaged state to the non-engaged state.

[0044] In summary, an embodiment of the present invention provides a control method for a vehicle power take-off. First, it is determined whether the power take-off needs to enter the working mode. If it is determined that it needs to enter the working mode, the clutch of the power take-off can be controlled to combine with the vehicle drive shaft to achieve energy acquisition; further, by comparing the driving speed and the calibrated speed of the power take-off, if the requirements are met, the speed of the power take-off can be adjusted using the vehicle's cruise control button. In general, the power take-off can be adaptively adjusted to its working state in different situations, thereby achieving more effective and accurate control of the power take-off and enriching the functionality of the vehicle.

[0045] Embodiment 2

[0046] Figure 2 is a flow chart of a control method for a vehicle power take-off provided by Embodiment 2 of the present invention, with reference to Figure 2 As shown, the second embodiment is refined on the basis of the above embodiment, and refines how to adjust the speed of the power take-off. In this embodiment, the method specifically includes the following steps:

[0047] S210, determining whether the power take-off of the vehicle has entered the working mode; if the power take-off has entered the working mode, executing S220; if the power take-off has not entered the working mode, executing S2100.

[0048] S220: Control the clutch of the power take-off to engage with the drive shaft of the vehicle.

[0049] S230, determining whether the driving speed exceeds the calibrated speed of the power take-off. If the driving speed does not exceed the calibrated speed of the power take-off, executing S240; if the driving speed exceeds the calibrated speed of the power take-off, executing S270;

[0050] S240, controlling the power take-off to operate at the initial speed.

[0051] Among them, after the clutch of the power take-off is combined with the drive shaft of the vehicle, that is, when the power take-off is in working mode, it has an original initial speed. The power take-off works at the initial speed when it just enters the working mode. According to different application situations, the speed of the power take-off needs to be adaptively adjusted to the operating speed to ensure the working efficiency of the power take-off. Among them, the speed adjustment of the power take-off can rely on the cruise control button, and the cruise control button includes an acceleration button and a deceleration button. The acceleration button can increase the speed at the initial speed, and the deceleration button can reduce the speed at the initial speed.

[0052] S250, control the acceleration button to start or the deceleration button to start, and adjust the initial speed to the operating speed.

[0053] Among them, the control accelerator button is started or the decelerator button is started, and the initial speed is adjusted to the operating speed. Specifically, if the control accelerator button is started, the adjusted operating speed includes the initial speed plus the first adjusted speed; if the control decelerator button is started, the adjusted operating speed includes the initial speed minus the first adjusted speed. The numerical value of the first adjusted speed can be adaptively adjusted according to demand, and the embodiment of the present invention does not specifically limit this.

[0054] There are various ways to adjust the initial speed to the operating speed, and adaptive adjustments can be made according to different needs. Figure 3 This is a partial flow chart of a control method for a vehicle power take-off provided in Embodiment 2 of the present invention, with reference to Figure 2 and Figure 3 As shown, controlling the acceleration button to start or the deceleration button to start, and adjusting the initial speed to the operating speed may include the following steps:

[0055] S251, control the acceleration button to start at the first time, and the operating speed includes the initial speed plus the first-stage adjustment speed.

[0056] S252, control the deceleration button to start at the first time, and the operating speed includes the initial speed minus the first-stage adjustment speed.

[0057] S253, control the deceleration button to start at the second time, and the operating speed includes the initial speed plus the second-stage adjustment speed.

[0058] S254, controlling the deceleration button to start at the second time, the operating speed includes the initial speed minus the second-stage adjustment speed.

[0059] Specifically, refer to Figure 3 As shown, any one of steps S251, S252, S253 and S254 can be executed for the speed adjustment process of the power take-off. Wherein the duration of the first time is greater than the duration of the second time, the corresponding S251 and S252 can be understood as tapping, and the corresponding S253 and S254 can be understood as long pressing. Wherein, the first-order speed adjustment is greater than the second-order speed adjustment, which can be understood as the time period of tapping, and the amplitude of speed adjustment by tapping is smaller than the amplitude of speed adjustment by long pressing. By further dividing the functions of the acceleration button and the deceleration button, the corresponding speed can be adjusted according to the activation time of the button. The duration of button activation and the speed adjustment amplitude can be adaptively adjusted according to different needs, and the embodiment of the present invention does not make specific limitations on this.

[0060] S260: Acquire and store the operating speed, and control the operating speed to replace the initial speed.

[0061] Furthermore, the adjusted operating speed can be stored and replace the original initial speed, so that the next time the power take-off working mode is started, the adjusted speed can be used directly for operation. In other words, the last speed before exiting the working mode should be memorized, and when the vehicle re-enters the working mode, the last speed can be automatically read. In this way, after adjusting a speed, the vehicle can directly read it next time without repeated adjustment.

[0062] S270, determining whether the driving speed exceeds the cruise control calibrated speed, if the driving speed exceeds the cruise control calibrated speed, executing S290; if the driving speed does not exceed the cruise control calibrated speed, executing S280;

[0063] Specifically, if the vehicle's speed exceeds the calibrated speed of the power take-off, it proves that the current speed is too high, or that it is not conducive to starting the working mode of the power take-off at this speed, and the power take-off will not start the working mode. Therefore, when the driving speed exceeds the calibrated speed of the power take-off, the speed of the power take-off cannot be adjusted. The function of the cruise control button can be adjusted in more detail in combination with the driving speed to ensure the safety and reliability of the vehicle. Specifically, when the driving speed has exceeded the calibrated speed of the power take-off, the relationship between the driving speed and the calibrated speed of the cruise control is determined.

[0064] S280, the function of controlling the cruise control button is suspended.

[0065] Specifically, when the vehicle speed does not exceed the cruise control calibrated speed, the function of the cruise control button is suspended, that is, the cruise control button is in a blank state, and no related action is performed even if the cruise control button is activated.

[0066] The cruise control calibrated speed can be understood as a pre-set threshold value, and the cruise control calibrated speed is greater than the power take-off calibrated speed. If the vehicle's speed is less than or equal to the threshold value, it proves that the current vehicle speed is not high, or that the difference between the current vehicle speed and the power take-off calibrated speed is small. In this case, the cruise control button (acceleration button or deceleration button) does not immediately adjust the vehicle's speed, thereby ensuring that there is no interference between the vehicle's cruise control mode and the power take-off working mode, ensuring the reliability and stability of the vehicle.

[0067] S290, the cruise control button is used to adjust the driving speed.

[0068] Specifically, when the vehicle's driving speed exceeds the cruise control calibrated speed, the cruise control button can be used to adjust the driving speed, that is, when the acceleration button is activated, the vehicle's running speed increases; when the deceleration button is activated, the vehicle's running speed decreases.

[0069] Furthermore, if the vehicle's speed is greater than the cruise control calibrated speed, it means that the current vehicle speed is high, or the difference between the current vehicle speed and the power take-off calibrated speed is large. In this case, the cruise control button (acceleration button or deceleration button) is used to adjust the vehicle's speed, which can also ensure that there is no interference between the vehicle's cruise control mode and the power take-off working mode, thereby ensuring the reliability and stability of the vehicle.

[0070] S2100: The clutch controlling the power take-off is not engaged with the drive shaft of the vehicle.

[0071] In summary, the control method of the vehicle power take-off provided in the embodiment of the present invention realizes efficient and reliable operation of the power take-off by refining how to adjust the rotational speed of the power take-off; at the same time, the function of the cruise control button can be adjusted according to different driving speeds to ensure the overall safety of the vehicle.

[0072] Embodiment 3

[0073] Figure 4 1 is a flow chart of a control method for a vehicle power take-off provided in Embodiment 3 of the present invention. Embodiment 3 is a refinement on the basis of the above-mentioned embodiment, which refines how to judge or start the working mode of the power take-off. In this embodiment, the method specifically includes the following steps:

[0074] S310: Obtain the initial gear position of the vehicle.

[0075] The gear position of the vehicle includes a parking gear and a driving gear, wherein the driving gear includes a forward gear and a reverse gear. The initial gear position of the vehicle can be understood as the gear position of the vehicle when the vehicle is determining whether to start the working mode of the power take-off. Furthermore, the working mode of the power take-off is selected according to the gear position of the vehicle. Specifically, determining whether the power take-off of the vehicle enters the working mode includes: determining whether the power take-off of the vehicle enters the parking mode or the driving mode. When the initial gear position obtained is in the parking gear, the determination process is to determine whether the power take-off of the vehicle enters the parking mode; when the initial gear position obtained is in the driving gear, the determination process is to determine whether the power take-off of the vehicle enters the driving mode.

[0076] Specifically, judging whether the power take-off of the vehicle enters the working mode, whether it is the parking mode or the driving mode, includes the following steps:

[0077] S320, determining whether the power value is greater than or equal to a preset power value, if the power value is greater than or equal to the preset power value, executing S340; if the power value is less than the preset power value, executing S330.

[0078] Among them, when the vehicle is a fuel vehicle, the power value of the vehicle can be understood as the amount of oil in the vehicle, and judging whether the power value is greater than or equal to the preset power value can be understood as whether the current amount of oil in the vehicle can support the vehicle to operate in the power take-off mode. Alternatively, when the vehicle is an electric vehicle, the power value of the vehicle can be understood as the amount of electricity in the vehicle, and judging whether the power value is greater than or equal to the preset power value can be understood as whether the current amount of electricity in the vehicle can support the vehicle to operate in the power take-off mode.

[0079] If the power value is insufficient, the power take-off will not operate, and the clutch of the power take-off will not engage with the vehicle's drive shaft.

[0080] S330: Control the clutch of the power take-off to be disconnected from the drive shaft of the vehicle.

[0081] S340, determining whether the power take-off working switch is activated, if the power take-off working switch is activated, executing S350; if the power take-off working switch is not activated, executing S330.

[0082] If the power value is sufficient, the power take-off is initially determined to be in working mode, and then the state of the power take-off working switch is judged. The power take-off working switch can be understood as a power switch that controls whether the power take-off is in working mode. If the power take-off working switch is activated, it proves that the operator or controller has output an instruction that requires the power take-off to work; if the power take-off working switch is not activated, it proves that the operator or controller has not output an instruction that requires the power take-off to work, and then the clutch of the power take-off is not engaged with the drive shaft of the vehicle.

[0083] S350, determining whether the current gear position of the vehicle is consistent with the initial gear position, if the current gear position of the vehicle is consistent with the initial gear position, executing S360; if the current gear position of the vehicle is inconsistent with the initial gear position, executing S330.

[0084] Furthermore, if the power value of the vehicle is sufficient and the power take-off working switch is started at the same time, it proves that the power take-off can initially enter the working mode. Next, it is necessary to obtain the current gear of the vehicle and determine whether the current gear of the vehicle is consistent with the initial gear. Exemplarily, if the initial gear is the parking gear and the current gear is also the parking gear, then whether the current gear of the entire vehicle is consistent with the initial gear; or if the initial gear is the forward gear and the current gear is also the forward gear, then whether the current gear of the entire vehicle is consistent with the initial gear; or if the initial gear is the reverse gear and the current gear is also the forward reverse gear, then whether the current gear of the entire vehicle is consistent with the initial gear. If the gear does not change, S360 can be continued to be executed; if the gear changes, S330 is executed. It should be noted that when the power take-off is in the working mode, if the gear changes, S330 is also executed.

[0085] S360, controlling the clutch of the power take-off to engage with the drive shaft of the vehicle.

[0086] S370: Determine whether the driving speed exceeds the calibrated speed of the power take-off.

[0087] S380, the cruise control button of the vehicle is used to adjust the speed of the power take-off.

[0088] S390. Control the power take-off of the vehicle to exit the working mode.

[0089] Furthermore, when the working mode of the vehicle power take-off ends, it is necessary to control the vehicle power take-off to exit the control mode, and it is necessary to control the clutch of the power take-off to disengage from the drive shaft of the vehicle.

[0090] In summary, an embodiment of the present invention provides a control method for a vehicle power take-off. By specifically describing how to control the working mode of the power take-off, it is demonstrated that the control method for a vehicle power take-off provided by the present invention has stability and reliability.

[0091] Embodiment 4

[0092] Figure 5 This is a schematic diagram of the structure of a vehicle power take-off control device provided in the fourth embodiment of the present invention. The technical solution of this embodiment can be applied to the case where the power take-off on the vehicle is adjusted. The device can be implemented by software and / or hardware and is generally integrated on any electronic device with network communication function, including but not limited to: servers, computers, personal digital assistants and other devices. Figure 5 As shown, the control device 100 of the vehicle power take-off provided in this embodiment may include: a working mode judgment module 200 and a form speed comparison module 300.

[0093] Among them, the working mode judgment module 200 is used to judge whether the power take-off of the vehicle enters the working mode; the working mode includes driving mode or parking mode; if the power take-off enters the working mode, the clutch of the power take-off is controlled to be combined with the drive shaft of the vehicle; if the power take-off does not enter the working mode, the clutch of the power take-off is controlled not to be combined with the drive shaft of the vehicle.

[0094] The speed comparison module 300 is used to obtain the driving speed of the vehicle.

[0095] The speed comparison module 300 also includes a driving speed and a power take-off calibrated speed judgment module 310, which is used to judge whether the driving speed exceeds the power take-off calibrated speed; if the driving speed does not exceed the power take-off calibrated speed, the vehicle's cruise control button is controlled to adjust the speed of the power take-off.

[0096] Optionally, the speed comparison module 300 also includes a driving speed and cruise control calibrated speed judgment module 320. When the driving speed exceeds the power take-off calibrated speed, the driving speed and cruise control calibrated speed judgment module 320 is used to judge whether the driving speed exceeds the cruise control calibrated speed; wherein the cruise control calibrated speed is greater than the power take-off calibrated speed; if the driving speed does not exceed the cruise control calibrated speed, the function of the cruise control button is controlled to be suspended; if the driving speed exceeds the cruise control calibrated speed, the cruise control button is controlled to adjust the driving speed.

[0097] Optionally, the control device of the vehicle power take-off further includes:

[0098] The initial speed operation control module is used to control the power take-off to operate at the initial speed.

[0099] The operating speed adjustment module is used to control the start of the acceleration button or the deceleration button, and adjust the initial speed to the operating speed; wherein, when the acceleration button is started, the operating speed includes the initial speed plus the first adjustment speed; when the deceleration button is started, the operating speed includes the initial speed minus the first adjustment speed.

[0100] The operating speed storage module is used to obtain and store the operating speed, and control the operating speed to replace the initial speed.

[0101] The initial gear position acquisition module is used to obtain the initial gear position of the vehicle.

[0102] The vehicle power value acquisition and judgment module is used to acquire the power value of the vehicle and judge whether the power value is greater than or equal to a preset power value. If the power value is not greater than or equal to the preset power value, the clutch of the power take-off is controlled not to be coupled with the drive shaft of the vehicle.

[0103] The power take-off switch judgment module is used to judge whether the power take-off switch is activated if the power value is greater than or equal to the preset power value. If the power take-off switch is not activated, the clutch of the power take-off is controlled to be not engaged with the drive shaft of the vehicle.

[0104] The current gear and initial gear judgment module is used to judge whether the current gear of the vehicle is consistent with the initial gear if the power take-off working switch is turned on. If the current gear of the vehicle is not consistent with the initial gear, the clutch of the power take-off is controlled to not engage with the drive shaft of the vehicle.

[0105] The working mode exit module is used to control the vehicle's power take-off to exit the working mode.

[0106] In summary, a control device for a vehicle power take-off provided in an embodiment of the present invention first utilizes a working mode judgment module to judge whether the power take-off needs to enter a working mode. When it is determined that the working mode needs to be entered, the clutch of the power take-off can be controlled to combine with the vehicle drive shaft to achieve energy acquisition; further, the driving speed and the calibrated speed of the power take-off are compared through a formal speed comparison module. When the requirements are met, the speed of the power take-off can be adjusted using the vehicle's cruise control button. In general, the power take-off can be adaptively adjusted to its working state in different situations, thereby achieving more effective and accurate control of the power take-off and enriching the functionality of the vehicle.
