[0026] As shown in Figure 1 and Figure 2 In the intelligent control method of the oil pedal of the engineering machinery, the engineering machinery includes a physical control device and an engine 101, and the control device includes a physical knob 104, an angle detection device, a controller 103 and an engine control module ECM 102. The physical knob 104 is used to be operated by a user to rotate in a first direction or in a second direction, one of the first direction and the second direction is a clockwise direction, and the other is a counterclockwise direction, that is, when the user controls the oil pedal, the control of the oil pedal is realized by rotating the physical knob. The angle detection device is in signal connection with the controller 103, and the angle detection device includes a rotary encoder and various detection devices capable of measuring the angular change of the physical knob.

[0027] The controller 103 is in signal connection with an engine control module ECM 102, which is in signal connection with an engine 101, and the controller 103 is in signal connection with the engine control module ECM 102. The controller can be a general purpose processor, a programmable logic controller (PLC), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any appropriate combination thereof, used to implement the functions described herein. ECM is the abbreviation of Engine Control Module, i.e. engine control module. The engine control module ECM is an electronic control system for monitoring and controlling the operation of the engine. The signal connections can be achieved by means of bus connection and / or wireless connection, thereby realizing the transmission of signals.

[0028] The intelligent control method for the oil pedal of the engineering machinery comprises the following steps:

[0029] The angle detection device detects the rotation direction and rotation angle of the physical knob 104 and sends the detection result to the controller 103; the controller 103 generates a control instruction according to the detection result of the angle detection device and sends it to the engine control module ECM 102; wherein when the angle detection device detects that the physical knob 104 rotates in the first direction and the rotation angle reaches a first threshold angle, the controller 103 increases the current throttle gear by m gears and controls the engine 101 to execute the corresponding speed of the throttle gear after increasing the gear through the engine control module ECM 102; when the angle detection device detects that the physical knob 104 rotates in the second direction and the rotation angle reaches a second threshold angle, the controller 103 reduces the current throttle gear by n gears and controls the engine 101 to execute the corresponding speed of the throttle gear after reducing the gear through the engine control module ECM 102. If the user needs to change the current throttle gear, he can achieve it by rotating the physical knob. In operation, if rotating in the first direction, for example, the first direction is clockwise and the second direction is counterclockwise, when the angle detection device detects that the user rotates the physical knob in the first direction and the rotation angle reaches a first threshold angle, the controller 103 increases the current throttle gear by m gears, m can be 1 or other integers, and then sends the engine speed to be executed to the engine control module ECM 102, and controls the engine to adjust the speed to the throttle speed corresponding to the changed gear through the engine control module ECM 102. When the angle of the physical knob rotated by the user reaches multiple first threshold angles, for example, 3, the controller 103 increases the current throttle gear by 3m gears, and controls the engine to adjust the speed to the throttle speed corresponding to the changed gear through the engine control module ECM 102. In operation, if rotating in the second direction, when the angle detection device detects that the user rotates the physical knob in the second direction and the rotation angle reaches a second threshold angle, the controller 103 reduces the current throttle gear by n gears, n can be 1 or other integers, and then sends the engine speed to be executed to the engine control module ECM 102, and controls the engine to adjust the speed to the throttle speed corresponding to the changed gear through the engine control module ECM 102. When the angle of the physical knob rotated by the user reaches multiple second threshold angles, for example, 3, the controller 103 reduces the current throttle gear by 3n gears, and controls the engine to adjust the speed to the throttle speed corresponding to the changed gear through the engine control module ECM 102. The first threshold angle and the second threshold angle can be set to be the same or different, for example, both are set to 10°. The values of m and n can be set to be the same or different, in the embodiment shown in the figure, the values of m and n are set to 1.

[0030] The intelligent control method for the throttle of the engineering machinery of the embodiment does not require the physical knob to correspond to the position of the throttle position one by one, but only needs to detect the rotation direction and rotation angle of the physical knob 104 through the angle detection device to increase or decrease the throttle position, the physical knob is more flexible to set, can more sensitively detect and respond to the increase and decrease demand of the operator for the throttle position, is more convenient for the operator to flexibly operate, and more intelligently controls the throttle position.

[0031] In some embodiments, when the angle detection device detects that the physical knob 104 rotates in the first direction and the rotation angle reaches a first threshold angle each time, the controller 103 increases the current throttle position by m positions includes: when the angle detection device detects that the physical knob 104 rotating in the first direction changes the rotation direction to the second direction or stops rotating for a first threshold time, when it is detected that the physical knob 104 rotates in the first direction again, the rotation angle of the physical knob 104 rotating in the first direction is calculated from the beginning of the rotation in the first direction again. If the operator operates the physical knob, continuously rotates in the first direction to increase the throttle position and then stops rotating or changes the direction to decrease the throttle position, since the angle of the physical knob rotating in the first direction or the angle exceeding part after reaching one or more first threshold angles is not enough to reach a first threshold angle, when the rotation direction is changed to the second direction, when the rotation direction is changed to the first direction again, the rotation angle of the physical knob in the first direction is calculated from the beginning of the change, that is, the part of the angle exceeding last time is zeroed and not calculated; when the rotation in the first direction is continued after stopping rotating for more than the first threshold time, the rotation angle of the physical knob in the first direction is calculated from the beginning of the continued rotation, that is, the part of the angle before stopping rotating is zeroed and not calculated. The first threshold time can be set to 0.5s and the like, which can be set according to the operation habit of the user. Similarly, when the angle detection device detects that the physical knob 104 rotating in the second direction changes the rotation direction to the first direction or stops rotating for a second threshold time, when it is detected that the physical knob 104 rotates in the second direction again, the angle of the physical knob 104 rotating in the second direction is calculated from the beginning of the rotation in the second direction again. The second threshold time can be set to 0.5s and the like, which can be set according to the operation habit of the user. The embodiment can more accurately judge the throttle position change intention of the user, better adapt to the habit of the user, and be more convenient for the user to operate.

[0032] In some embodiments, the method further comprises setting a maximum number of gears j corresponding to a maximum speed of the engine 101 by the controller 103, and limiting the increase of the gear position by the controller 103 when the gear position reaches the maximum number of gears j. In this embodiment, the speed of the engine 101 is divided into different gears, and the jth gear is the maximum gear. For example, when the maximum number of gears j is set to 3, the speed of the engine 101 is divided into 3 gears, and the 3rd gear is the maximum gear. When the maximum number of gears j is set to 5, the speed of the engine 101 is divided into 5 gears, and the 5th gear is the maximum gear. When the user continues to increase the gear position after the gear position reaches the maximum number of gears j, the controller 103 will not increase the gear position.

[0033] In some embodiments, the method further comprises setting a minimum speed and a maximum speed by the controller 103, and sending the current speed of the engine 101 to the controller 103 by the engine control module ECM 102. When the current speed of the engine 101 reaches the maximum speed, the controller 103 limits the increase of the speed of the engine 101. When the current speed of the engine 101 reaches the minimum speed, the controller 103 limits the decrease of the speed of the engine 101.

[0034] In some embodiments, the physical knob 104 is also used to be pressed down and automatically reset when pressed. The physical knob 104 can be automatically reset by setting a reset spring. When the physical knob 104 is pressed and the reset spring is compressed, the reset spring automatically resets the physical knob 104 when the physical knob 104 is released. The method further comprises setting a target gear position k by the controller 103, and switching the current gear position to the kth gear by the controller 103 when the physical knob 104 is pressed down, and controlling the engine 101 to execute the speed corresponding to the kth gear by the engine control module ECM 102. The target gear position can be the gear position frequently used by the user, and the user can directly reach the frequently used gear position by pressing the physical knob, which makes the operation more convenient and efficient.

[0035] In some embodiments, the construction machinery further comprises an electronic monitor 105 connected to the controller 103, and the electronic monitor 105 is provided with an analog knob for user operation. The analog knob corresponds to the physical knob 104, and when the analog knob is rotated in a first direction and the rotation angle reaches a first threshold angle, the controller 103 increases the current gear position by m gears. When the angle detection device detects that the physical knob 104 is rotated in a second direction and the rotation angle reaches a second threshold angle, the controller 103 decreases the current gear position by n gears. The electronic monitor is provided with an operation screen, and the operation screen is provided with an analog knob for user operation, which makes the user operation more diverse.

[0036] In some embodiments, the electronic monitor 105 is further configured to set the maximum number of gears j and / or the target number of gears k.

[0037] In some embodiments, the electronic monitor 105 is further provided with a gear display interface for displaying each gear of the engine 101, and the gear display interface is configured to display the currently selected gear by the user. The currently selected gear by the user when rotating the physical knob or the simulated knob can be displayed on the operation screen in real time, so that the user can be more clearly aware of the information.

[0038] In some embodiments, the electronic monitor 105 is further configured to set the maximum number of gears j, and the method for intelligently controlling the engine throttle of the construction machinery further comprises: calculating the economic number of gears under the current maximum number of gears j according to the maximum number of gears j set by the user by using the controller 103 and displaying the economic number of gears. The economic gear refers to a gear with good economy, i.e., an oil-saving gear. For an engine, the engine speed within a certain range is good in economy. When the maximum number of gears j is different, the engine speed good in economy is different for the number of gears, i.e., the economic number of gears is different. By displaying the economic number of gears, the user can be informed of the information of the economic number of gears in time and accurately select the economic number of gears.

[0039] In some embodiments, the electronic monitor 105 is further configured to set a memory state and a non-memory state. In the memory state, the current throttle gear of the engine 101 is stored. When the control device is restarted after power failure or the engine 101 is restarted after engine shutdown, the controller 103 sends a memory state instruction to the engine control module ECM 102, and the engine control module ECM 102 controls the throttle gear of the engine 101 to return to the throttle gear of the engine 101 before restart after receiving the memory state instruction. In the non-memory state, when the control device is restarted after power failure or the engine 101 is restarted after engine shutdown, the controller 103 does not send a memory state instruction to the engine control module ECM 102.

[0040] In some embodiments, a construction machinery is also disclosed, which applies any of the methods for intelligently controlling the engine throttle of the construction machinery. The construction machinery comprises a physical control device and an engine 101. The control device comprises a knob, an angle detection device, a controller 103, and an engine control module ECM 102. The physical knob 104 is configured to be operated by a user to rotate in a first direction or a second direction. One of the first direction and the second direction is a clockwise direction, and the other is a counterclockwise direction. The angle detection device is signal connected with the controller 103.
