[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0032] like Figures 1 to 4 As shown, a method for electric shifting of a hydrostatically driven harvester according to an embodiment of the present application is applied to a control device of an electric shifting system of a goods receiver, and the electric shifting system of the goods receiver also includes: a cab operation panel, a variable motor 1, a shifting structure, a gearbox 3, a gear selection motor 4, a shifting motor 5, a gear position sensor and an angle sensor; the variable motor 1 and the shifting mechanism 2 are respectively connected to the gearbox 3, and the shifting structure is respectively connected to the gear selection motor 4 and the shifting motor 5, and the shifting structure is provided with a gear position sensor; the method includes:

[0033] Step S101: The operator sends a shift instruction to the control device through the cab operation panel to determine the current driving demand of the receiver. The current driving demand includes the gearbox 3 being in a target gear range and the variable motor 1 being in a target speed range.

[0034] The operator issues a shift command through the cab operating panel to determine the current drive demand of the harvester, and the shift panel transmits the command to the control device through the CAN bus.

[0035] Step S102, the gear sensor collects the actual gear position of the gearbox 3, the angle sensor collects the actual speed of the variable motor 1, the control device receives the actual gear position and the actual speed and respectively determines whether the actual gear position meets the target gear range and whether the actual speed meets the target speed range.

[0036] The control device collects the current gear information of the receiver, the real-time driving motor speed, the handle position, the status of the gear selection motor and the gear shift motor, and other current status information of the harvester through sensors (gear selection displacement sensor 6 and gear shift displacement sensor 7) to determine whether the gear shift conditions are met. The gear shift conditions include: the control handle needs to be in the middle position, the motor speed needs to be below 100 rpm, the gear selection and shift motor is powered on normally, and the displacement sensor voltage is normal.

[0037] After the gear selection motor 4 selects a matching gear according to the current driving demand of the harvester, the gear shift motor 5 automatically switches to a matching gear after the gear shifting condition is met. The gear selection displacement sensor 6 is used to obtain the gear information selected by the gear selection motor 4, and the gear shift displacement sensor 7 is used to obtain whether the gear shift motor 5 is switched to a matching gear, thereby realizing intelligent monitoring of the gear selection operation and the gear shifting operation.

[0038] Step S103: If the actual speed does not meet the target speed range, the control device controls the variable speed motor 1 to deliver a speed that meets the target speed range.

[0039] The motor speed needs to be below 100 rpm, the shift motor must be powered normally, and the displacement sensor voltage must be normal.

[0040] Step S104: If the actual gear position does not meet the target gear position range, the control device controls the gear shifting to the gear position meeting the target gear shifting range through the gear shifting motor 5.

[0041] The electric shifting method for a hydrostatically driven harvester in an embodiment of the present application, wherein the control device controls the variable motor 1 to deliver a speed that satisfies a target speed range, comprises: the control device controls the hydrostatic system of the harvester to adjust the speed through a proportional valve, so that the variable motor 1 delivers a speed that satisfies the target speed range.

[0042] In combination with the above embodiments, based on the current driving demand and the current machine status information, the static hydraulic system is controlled to adjust the speed of the variable motor 1 through the proportional valve to output a speed below 100 rpm, so that the speed of the variable motor 1 meets the demand. The control device also controls the gear selection motor to execute the predetermined trajectory to move based on the set gear position and PID position control. The motor drives the shift head 8 to operate the gearbox 3 according to the set displacement position and through the shift mechanism to output different half-shaft speeds, and the wheel hub is driven to rotate. When the required gear shift is completed, the controller cuts off the motor hydraulic valve to reduce the motor speed to zero.

[0043] In the electric shifting method for a hydrostatically driven harvester according to an embodiment of the present application, the speed of the variable motor 1 in the target speed range is less than 100 revolutions per second.

[0044] The electric shifting method for a hydrostatically driven harvester in an embodiment of the present application, wherein the control device controls the gear shifting to a gear position that satisfies a target gear shifting range through the gear shifting motor 5, comprises: the control device controls the gear shifting motor to move along a predetermined trajectory, so that the gear shifting mechanism operates the gearbox 3 through the shift head 8 to output different half-shaft speeds.

[0045] In the electric shifting method for a hydrostatically driven harvester according to an embodiment of the present application, the target gear position includes the operating handle of the shift mechanism 2 being in the middle position, the gear selection position, and the gear shift position being in the target gear position.

[0046] In combination with the above embodiment, after determining the shift position according to the shift demand before shifting, it is necessary to determine whether the operating handle is in the middle position (that is, whether it is in the neutral state). When the operating handle is in the middle position, the shift handle is shifted to the target gear position through the shift head 8 on the shift mechanism 2.

[0047] The cab operation panel replaces the original gear lever design. By designing a new operation panel, buttons for 1st gear, 2nd gear, 3rd gear, 4th gear and neutral gear are added. The operator changes gears by pressing the buttons, reducing the space occupied by the control handle.

[0048] Based on the same inventive concept, the present application also provides a hydrostatically driven electric shifting system for a receiving machine. Since the implementation principle of the hydrostatically driven electric shifting system for a receiving machine of the present application is the same as that of a hydrostatically driven electric shifting method for a harvester, the implementation method of a hydrostatically driven electric shifting system for a receiving machine specifically refers to a hydrostatically driven electric shifting method for a harvester, and the similarities are not repeated here.

[0049] A hydrostatic drive receiver electric shift system according to an embodiment of the present application includes: a control device, a cab operation panel, a variable motor 1, a shift structure, a gearbox 3, a gear selection motor 4, a shift motor 5, a gear position sensor and an angle sensor: the variable motor 1 and the shift mechanism 2 are respectively connected to the gearbox 3, the shift structure is respectively connected to the gear selection motor 4 and the shift motor 5, and the shift structure is provided with a gear position sensor;

[0050] The cab operation panel is used for the operator to send a shift command to the control device to determine the current driving demand of the receiver, and the current driving demand includes the gearbox 3 being in the target gear range and the variable motor 1 being in the target speed range;

[0051] The gear position sensor collects the actual gear position of the gearbox 3, the angle sensor collects the actual speed of the variable motor 1, and the control device receives the actual gear position and the actual speed and determines whether the actual gear position meets the target gear position range and whether the actual speed meets the target speed range respectively;

[0052] If the actual speed does not meet the target speed range, the control device controls the variable motor 1 to deliver a speed that meets the target speed range;

[0053] If the actual gear position does not meet the target gear position range, the control device controls the gear shifting to the gear position meeting the target gear shifting range through the gear shifting motor 5 .

[0054] In combination with the above embodiments, based on the current driving demand and the current machine status information of the harvester, the static hydraulic system is controlled to adjust the speed of the variable motor 1 through the proportional valve to output a speed below 100 rpm, so that the speed of the variable motor 1 meets the demand. The control device also controls the gear selection motor to execute the predetermined trajectory to move based on the set gear position and PID position control. The motor drives the shift head 8 to operate the gearbox 3 according to the set displacement position and through the shift mechanism to output different half-shaft speeds and drive the wheel hub to rotate. When the required gear shift is completed, the controller cuts off the motor hydraulic valve to reduce the motor speed to zero, thereby realizing the intelligent gear shifting of the harvester.

[0055] The hydrostatic drive electric shift system of the goods receiver in the embodiment of the present application also includes a hydrostatic system, which is provided with a proportional valve; the control device controls the hydrostatic system to adjust the speed through the proportional valve, so that the variable motor 1 delivers a speed that meets the target speed range.

[0057] In combination with the above embodiments, the cab operating panel replaces the original gear lever design. By designing a new operating panel, buttons for 1st gear, 2nd gear, 3rd gear, 4th gear and neutral gear are added. The operator changes gears by pressing the buttons, reducing the space occupied by the operating handle.

[0058] The shift mechanism performs a shift operation according to the instruction. The controller receives the shift instruction from the cab operation panel and controls the shift mechanism to perform an intelligent shift operation on the gearbox 3 by controlling the shift motor 5 .

[0059] The vehicle comfort is improved by adjusting the current of the solenoid valve of the variable motor 1 in real time. The control device collects the voltage signals of the gear selection sensor and the gear shift sensor, obtains the gear information through the algorithm, and the controller adjusts the current of the proportional valve and the starting and braking current curves of the controller to slow down the drastic changes in vehicle speed to improve vehicle comfort.

[0060] Based on the above analysis, it can be seen that compared with the manual shifting method in the related art, the electric shifting method and system for a hydrostatically driven harvester provided by the embodiment of the present invention improves the vehicle comfort by adjusting the current of the solenoid valve of the variable motor 1 in real time.
