Description

Technical Field

[0001] The present application relates to the technical field of automatic gear shifting for driving operation vehicles, and in particular to an AMT control method, system, device and readable storage medium for driving operation vehicles. Background Art

[0002] In the current market, the control logic of the power take-off on sanitation vehicles matched with AMT gearboxes is as follows: in neutral state, the driver presses the power take-off switch to give a signal to the gearbox TCU, the TCU controls the power take-off clutch to engage, and the air tank supplies air to the power take-off cylinder. After the cylinder is ventilated, the power take-off and the gearbox are combined.

[0003] Existing sanitation watering vehicles are often used for multiple purposes, and one vehicle is used for multiple operating conditions. For example, the common speed of a watering truck is 15-20km / h, and the current AMT vehicles can meet the operating requirements. However, in some operating conditions, such as nighttime operation of watering trucks, the speed must be increased as much as possible, or in some special operating environments such as spreading snow-melting agents on snowy days. However, since the gearbox needs to be unloaded when the vehicle shifts gears automatically, the vehicle body is required to release the connection with the gearbox during the automatic shifting process. However, since the power take-off of the existing sanitation vehicle body is rigidly connected to the gearbox, the power take-off connected to the gearbox cannot be disengaged during the operation of the gearbox. Therefore, the driver cannot automatically change gears and adjust the vehicle speed during driving according to the current operating conditions and actual usage needs. At the same time, since the vehicle body cannot temporarily take power while the vehicle is driving, it is necessary to take power during the vehicle starting process. The speed that can be achieved by the vehicle's starting gear is relatively low, and the maximum speed can only reach 15 to 20 km / h. Ultimately, when the vehicle body is operating, the vehicle speed cannot meet customer usage needs. Summary of the invention

[0045] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0046] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0047] In the current market, the control logic of the power take-off on sanitation vehicles matched with AMT gearboxes is as follows: in neutral state, the driver presses the power take-off switch to give a signal to the gearbox TCU, the TCU controls the power take-off clutch to engage, and the air tank supplies air to the power take-off cylinder. After the cylinder is ventilated, the power take-off and the gearbox are combined.

[0048] Existing sanitation watering vehicles are often used for multiple purposes, and one vehicle is used for multiple operating conditions. For example, the common speed of a watering truck is 15-20km / h, and the current AMT vehicles can meet the operating requirements. However, in some operating conditions, such as nighttime operation of watering trucks, the speed must be increased as much as possible, or in some special operating environments such as spreading snow-melting agents on snowy days. However, since the gearbox needs to be unloaded when the vehicle shifts gears automatically, the vehicle body is required to release the connection with the gearbox during the automatic shifting process. However, since the power take-off of the existing sanitation vehicle body is rigidly connected to the gearbox, the power take-off connected to the gearbox cannot be disengaged during the operation of the gearbox. Therefore, the driver cannot automatically change gears and adjust the vehicle speed during driving according to the current operating conditions and actual usage needs. At the same time, since the vehicle body cannot temporarily take power while the vehicle is driving, it is necessary to take power during the vehicle starting process. The speed that can be achieved by the vehicle's starting gear is relatively low, and the maximum speed can only reach 15 to 20 km / h. Ultimately, when the vehicle body is operating, the vehicle speed cannot meet customer usage needs.

[0049] Based on the above problems, the present application provides a method, system, device and readable storage medium for controlling an AMT of a driving operation vehicle.

[0050] First, refer to Figure 1 The embodiment of the present application provides an AMT control system for a driving operation vehicle, which includes:

[0051] AMT gearbox 1;

[0052] A top-mounted power take-off 2, which is transmission-connected to the top-mounted vehicle;

[0053] A power take-off clutch device, which is drivingly connected to the upper mounted power take-off 2 and is configured to be capable of drivingly connecting to / disconnecting from the AMT gearbox 1 in a running state;

[0054] The transmission control unit 3 is configured to respond to the shift signal automatically sent by the AMT transmission 1 according to the vehicle speed change, and after determining that the vehicle body is in the working state, control the body power take-off 2 to separate from the AMT transmission 1 in the operating state; and execute the vehicle's shift operation, and control the body power take-off 2 in the separated state to connect with the AMT transmission 1 after the shift.

[0055] Specifically, the upper-mounted power take-off 2 is connected / disconnected with the AMT gearbox 1 through a power take-off clutch device. At the same time, since the power take-off clutch device can be connected / disconnected with the AMT gearbox 1 in the operating state, the upper-mounted power take-off 2, that is, the vehicle upper-mounted power take-off, can be connected or disconnected when the AMT gearbox 1 is running. Therefore, for a vehicle whose upper-mounted power take-off is in operation, when its AMT gearbox 1 needs to perform automatic gear shifting according to the automatic gear shifting logic, the upper-mounted power take-off 2 can be directly disengaged and then shifted under the control of the gearbox control unit 3, and the upper-mounted power take-off can be performed again after the gear shift is completed, thereby finally completing the gear shift during the driving of the vehicle, and the upper-mounted operation can be continued before and after the gear shift.

[0056] Furthermore, in some embodiments, the power take-off clutch device includes:

[0057] An air reservoir 4, whose air delivery port is connected to a power take-off solenoid valve 5, and the power take-off solenoid valve 5 is control-connected to the gearbox control unit 3;

[0058] A power take-off cylinder 6, which is connected to the power take-off solenoid valve 5, and whose output shaft moves according to the air supply of the air reservoir 4;

[0059] The power take-off clutch 7 is drivingly connected to the upper mounted power take-off 2 and is configured to connect / disconnect the AMT gearbox 1 according to the movement position of the output shaft of the power take-off cylinder 6 and the operating state.

[0060] The power take-off clutch 7 and the output shaft of the AMT gearbox 1 are connected by friction. Specifically, when the power take-off solenoid valve 5 is opened and the air reservoir 4 delivers air pressure into the power take-off cylinder 6, the output shaft of the power take-off cylinder 6 will drive the power take-off clutch 7 to gradually approach and finally press-fit with the output shaft of the AMT gearbox 1 during the movement, thus realizing strong friction transmission. At the same time, due to the strong friction transmission between the power take-off clutch 7 and the AMT gearbox 1, the power take-off clutch 7 can be connected / disconnected by transmission when the AMT gearbox 1 is running, thereby ensuring that the power take-off clutch device can be connected / disconnected by transmission when the AMT gearbox 1 is running.

[0061] Furthermore, in some embodiments, the AMT control system for the driving operation vehicle is characterized by further comprising:

[0062] A pressure switch 8, which is configured to be opened and closed according to the cylinder pressure in the power take-off cylinder 6 and is control-connected to the AMT gearbox 1 control unit;

[0063] The AMT gearbox 1 control unit determines whether the power take-off clutch 7 is connected to the AMT gearbox 1 according to whether the pressure switch 8 is closed.

[0064] In this embodiment, the pressure switch 8 is opened and closed according to the cylinder pressure in the power take-off cylinder 6, and the pressure switch 8 is closed when the cylinder pressure is greater than the set value. When the cylinder pressure is greater than the set value, the power take-off clutch 7 will maintain a strong friction transmission connection with the output shaft of the AMT gearbox 1. At this time, the closed state of the pressure switch 8 will be fed back to the AMT gearbox 1 control unit, so that it can be known whether the vehicle body is in an operating state.

[0065] Furthermore, in some embodiments, the driving operation vehicle AMT control system further includes:

[0066] An angular velocity sensor 9, which is configured to detect the rotation speed of the transmission shaft 10 of the upper mounted power take-off 2 and is control-connected to the control unit of the AMT gearbox 1;

[0067] The AMT gearbox 1 control unit is also configured to obtain the rotational speed of the transmission shaft 10 of the upper-mounted power take-off 2 when the upper-mounted power take-off 2 is connected to the AMT gearbox 1; determine whether the rotational speed of the transmission shaft is greater than a set rotational speed threshold; if greater, control the upper-mounted power take-off 2 to separate from the AMT gearbox 1 in the running state.

[0068] Specifically, the angular velocity sensor 9 is connected to the gearbox control unit 3 through a hard line. When the speed of the transmission shaft 10 of the upper mounted power take-off 2 exceeds the rated speed of the upper mounted structure, the angular velocity sensor 9 will send a signal to the gearbox control unit 3, and the gearbox control unit 3 will control the power take-off solenoid valve 5 to be disconnected, and the power take-off cylinder 6 will drive the power take-off clutch 7 to be separated. At this time, the transmission shaft 10 of the upper mounted power take-off 2 is separated from the power take-off, protecting the upper mounted structure from working under overload to avoid damage.

[0069] In one embodiment, referring to Figure 2 , Figure 2 This is a flow chart of the first embodiment of the AMT control method for a driving operation vehicle of the present application. Figure 2 As shown, the AMT control method for a driving operation vehicle includes:

[0070] S100, responding to the automatic shift signal automatically sent by the AMT gearbox 1 according to the vehicle speed change, after determining that the vehicle body is in an operating state, controlling the power take-off clutch device connected to the body power take-off 2 to separate from the AMT gearbox 1 in the operating state;

[0071] S200, executing a gear shifting operation of the vehicle, and controlling the power take-off clutch device to be connected to the AMT gearbox 1 after the gear shifting.

[0072] Specifically, during the driving process of the vehicle, whether the vehicle body is in working state is determined by whether the pressure switch 8 is closed. If it is in the engaged state, the gearbox control unit 3 controls the power take-off solenoid valve 5 to disconnect, so that the power take-off clutch device is separated from the AMT gearbox 1, and then the normal gear shifting operation of the vehicle is performed (including the disconnection between the AMT gearbox 1 and the engine, the internal gear shifting of the AMT gearbox 1, and the reconnection of the engine to the AMT gearbox 1 after the internal gear shifting of the AMT gearbox 1). After the gear shifting is completed, the gearbox control unit 3 controls the power take-off solenoid valve 5 to engage, so that the belt power take-off clutch device is engaged. When the closing signal of the pressure switch 8 is fed back to the gearbox control unit 3, the driving gear shifting and power take-off are completed.

[0073] Furthermore, in one embodiment, the following steps are also included:

[0074] S300, when the power take-off clutch device is connected to the AMT gearbox 1, obtaining the rotation speed of the transmission shaft 10 of the upper mounted power take-off 2;

[0075] S400, determining whether the transmission shaft speed is greater than a set speed threshold;

[0076] S500: If it is greater than, control the upper mounted power take-off 2 to be separated from the AMT gearbox 1 in the running state.

[0077] In this embodiment, when the speed of the transmission shaft 10 of the upper-mounted power take-off 2 exceeds the rated speed of the upper-mounted structure, the angular velocity sensor 9 will send a signal to the gearbox control unit 3, and the gearbox control unit 3 will control the power take-off solenoid valve 5 to disconnect, and the power take-off cylinder 6 will drive the power take-off clutch 7 to separate. At this time, the transmission shaft 10 of the upper-mounted power take-off 2 is separated from the power take-off, protecting the upper-mounted structure from working under overload to avoid damage.

[0078] Furthermore, in one embodiment, the following steps are also included:

[0079] S600, responding to the gear lock signal, controlling the AMT transmission 1 to enter the gear lock mode; wherein, in the gear lock mode, the AMT transmission 1 no longer responds to the automatic gear shift signal.

[0080] Specifically, step S600, responding to the gear lock signal, controlling the AMT transmission 1 to enter the gear lock mode; wherein, in the gear lock mode, before responding to the automatic shift signal, the AMT transmission 1 includes the following steps:

[0081] S510, determining whether an input manual gear lock command is obtained, or whether the current vehicle speed is maintained within a set range within a set time period;

[0082] S520: If the manual gear lock instruction is obtained, or the current vehicle speed is maintained within a set range within a set time period, a gear lock signal is output.

[0083] In this embodiment, whether to send a gear lock signal is determined by manual input or according to the current vehicle speed. After receiving the gear lock signal, the gear lock mode is entered, the current gear is locked and the gear is not automatically changed, thereby reducing the driver's workload. In addition, the driver can also control the AMT transmission 1 to exit the gear lock mode by manually inputting a command to release the gear lock mode.
