The driving motor can be provided with a position encoder, the position information of the shifting fork can comprise the rotation angle of the motor fed back by the position encoder, and the position of the shifting fork can be determined according to the rotation angle of the motor and the transmission ratio between the motor and the shifting fork.
In step S12, if it is determined that the current position of the shift fork represented by the position information does not correspond to the target driving mode of the vehicle, the driving motor needs to be controlled to drive the shift fork to move to the position corresponding to the target driving mode. Therefore, an action command is sent to the driving motor, and the action command is used for indicating the driving motor to drive the shifting fork to move to the position corresponding to the target driving mode for preset time.

FIG. 2 is a schematic structural view of a front axle fork provided according to an exemplary embodiment of the present disclosure; FIG. 3 is a cross-sectional view of a front axle fork provided in accordance with an exemplary embodiment of the present disclosure. Referring to fig. 2 and 3, the differential may be disposed in a front axle assembly 1, and a transmission shaft connecting portion 2 may be disposed on the front axle assembly 1, where the transmission shaft connecting portion 2 is used to connect a front axle transmission shaft, and the front axle transmission shaft may be connected with a front output shaft of the transfer case. The front axle assembly 1 is internally provided with a driving gear and a driven gear engaged with the driving gear, the driven gear can be fixedly connected with the differential shell, and power can be transmitted to the differential shell through a transfer case, a transfer case front output shaft, a front axle transmission shaft, the driving gear and the driven gear. The differential mechanism can be internally provided with two side gears, one side gear is connected with a first long half shaft 3, the first long half shaft 3 can be connected with a second long half shaft 4 fixed on a driving shaft through a front axle shifting fork so as to realize the connection of the first long half shaft 3 and the driving shaft, the driving shaft is connected with a first front wheel, and the other side gear of the differential mechanism is connected with a second front wheel of a vehicle.
For example, the sleeve 5 may be slidably disposed on the first half shaft 3, while the second half shaft 4 may be provided with splines that mate with spline grooves of the sleeve 5, and the sleeve 5 may mate with splines on the second half shaft 4 to connect the first half shaft 3 with the second half shaft 4. A driving motor 7 can be arranged in the front axle shifting fork, an output shaft of the driving motor 7 can be connected with a gear, the gear is meshed with a rack 8, and the rack 8 can be fixedly connected with the shifting fork 6. Thus, when the output shaft of the driving motor 7 rotates, the rack 8 can drive the shifting fork 6 to slide, and the shaft sleeve 5 can slide. The shifting fork 6 can drive the shaft sleeve 5 to slide along different directions by controlling the driving motor 7 to rotate forwards and reversely.
Illustratively, the method may further comprise: and if the number of times of driving the shifting fork to move by the driving motor reaches the preset number of times and the current position of the shifting fork does not correspond to the target driving mode, controlling the prompting device to prompt prompting information corresponding to the fault of the front axle shifting fork.
In this scheme, if the number of times that driving motor drive shift fork removed reaches and predetermines the number of times, and the current position of shift fork does not correspond with target drive mode, can confirm the front axle shift fork trouble this moment, control suggestion device suggestion prompt information corresponding to the front axle shift fork trouble this moment to the user maintains fast, prevents that the user from frequently controlling the driving motor action and leading to the overheated possibility of damage even of driving motor.
Illustratively, the driving modes of the vehicle may include a two-wheel drive mode and a four-wheel drive mode, and the method may further include: in a case where a mode switching instruction for instructing the vehicle to switch between the two-wheel drive mode and the four-wheel drive mode is received, the drive mode instructed by the mode switching instruction is determined as a target drive mode.
For example, in a case where the mode switching command is received, if it is determined that the current position of the fork represented by the position information does not correspond to the target driving mode of the vehicle, sending an action command to the driving motor may include:
and if the current working state of the transfer case is determined to correspond to the target driving mode and the current position of the shifting fork represented by the position information does not correspond to the target driving mode, sending an action command to the driving motor.
In this embodiment, when the mode switching instruction is received, the transfer case may be controlled to switch to the driving mode indicated by the mode switching instruction. For example, if the switching mode indicated by the mode switching instruction is the two-drive mode, the transfer case may be first controlled to switch to the working state corresponding to the two-drive mode. And under the condition that the current working state of the transfer case is determined to correspond to the target driving mode and the current position of the shifting fork represented by the position information does not correspond to the target driving mode, sending an action instruction to the driving motor so that the driving motor drives the shifting fork to move.
For example, if a mode switching instruction is not received, it may be determined that the initial driving mode of the vehicle is the target driving mode.
Illustratively, the method may further include: and if the current position of the shifting fork is determined to correspond to the target driving mode, controlling a prompting device to prompt prompting information corresponding to the fact that the vehicle is currently in the target driving mode.
Fig. 4 is a flowchart of a control method of a front axle shift fork according to an exemplary embodiment of the present disclosure. Referring to fig. 4, the method may include steps S21 to S28.
In step S21, position information of the shift fork is acquired. According to the position information of the shifting fork, the current position of the shifting fork can be determined.
In step S22, it is determined whether the current position of the shift fork corresponds to the target drive mode of the vehicle, and a first determination result is generated.
For example, the driving modes of the vehicle may include a two-wheel drive mode, a four-wheel drive mode, and a low-speed four-wheel drive mode. When the shifting fork is located at a first position corresponding to the two-drive mode, the shaft sleeve disconnects the first long half shaft from the driving shaft; when the shifting fork is located at a second position corresponding to the four-wheel drive mode and the low-speed four-wheel drive mode, the shaft sleeve connects the first long half shaft with the driving shaft.
The target drive mode may be determined by: determining the driving mode indicated by the mode switching instruction as a target driving mode in the case of receiving a mode switching instruction for instructing the vehicle to switch between the two-wheel drive mode and the four-wheel drive mode; and if the mode switching instruction is not received, determining that the initial driving mode of the vehicle is the target driving mode.
For example, if the initial driving mode is the two-drive mode and the mode switching instruction is not received, it may be determined that the target driving mode is the two-drive mode; if the initial driving mode is the four-wheel drive mode and the mode switching instruction is not received, determining that the target driving mode is the four-wheel drive mode; if the initial driving mode is the low-speed four-wheel drive mode and the mode switching instruction is not received, the target driving mode can be determined to be the low-speed four-wheel drive mode.
If the initial driving mode is a two-wheel drive mode and a mode switching instruction for indicating the vehicle to be switched to a four-wheel drive mode is received, determining that the target driving mode is the four-wheel drive mode; if the initial driving mode is a two-wheel driving mode and a mode switching instruction for indicating the vehicle to be switched to a low-speed four-wheel driving mode is received, determining that the target driving mode is the low-speed four-wheel driving mode; if the initial driving mode is the four-wheel drive mode or the low-speed four-wheel drive mode and a mode switching instruction for instructing the vehicle to switch to the two-wheel drive mode is received, it may be determined that the target driving mode is the two-wheel drive mode.
In the case where the first determination result is yes, step S27 may be executed at this time, and the control prompting device prompts the prompting information corresponding to the vehicle being currently in the target drive mode. For example, the meter display target drive mode of the vehicle may be controlled.
Of course, when the mode switching command is received, it may be determined whether or not the current operating state of the transfer corresponds to the target drive mode, and when the current operating state of the transfer corresponds to the target drive mode and the first determination result is yes, the step S27 may be executed.
Under the condition that the first judgment result is negative, the driving motor is required to be controlled to drive the shifting fork to move to the position corresponding to the target driving mode. Therefore, step S23 is executed to send an action command to the driving motor, where the action command is used to instruct the driving motor to drive the shift fork to move to the position corresponding to the target driving mode for a preset time.
After the driving motor is operated, step S24 may be performed to determine whether the current position of the shift fork corresponds to the target driving mode, and generate a second determination result. In a case where the second determination result is yes, the above-described step S27 may be performed.
If the second determination result is negative, step S25 may be executed to determine whether the number of times the driving motor drives the shift fork to move reaches a preset number of times, and generate a third determination result.
In the case that the third determination result is yes, the number of times that the driving motor drives the shift fork to move has reached the preset number of times, and it may be determined that the front axle shift fork is out of order, and therefore step S28 is performed, and the control prompting device prompts a prompting message corresponding to the front axle shift fork out of order. For example, the instrument display can be an electric control fork fault.
If the third determination result is no, step S26 may be executed to extend the preset time in the operation command. And then the above step S23 is re-executed. Like this, under the circumstances that the number of times that driving motor drive shift fork removed does not reach preset number of times, carry out step S23 again at every turn, the motor drives the equal extension of the preset duration that the shift fork removed, under the great circumstances of the sliding resistance of axle sleeve, the shift fork of being convenient for drives the axle sleeve and slides, and then the shift fork of being convenient for removes to the position that corresponds with target drive mode.
FIG. 5 is a schematic illustration of vehicle signaling provided in accordance with an exemplary embodiment of the present disclosure. Referring to fig. 5, the control method of the front axle fork described above can be applied to a four-wheel drive controller, for example. The vehicle CAN be provided with a four-wheel drive switch, the four-wheel drive switch CAN be communicated with the vehicle body Controller through a LIN (Local Interconnect Network, chinese) line, the vehicle body Controller CAN be communicated with the four-wheel drive Controller through a CAN (Controller Area Network), and the four-wheel drive Controller CAN be communicated with the display instrument through a CAN (Controller Area Network, chinese) bus.
When the driver wants to switch between the four-wheel drive mode and the two-wheel drive mode, the driver CAN send out a switch request signal (for example, the switch request signal CAN comprise a mode switching instruction) through the four-wheel drive switch, and the switch request signal is transmitted to the vehicle body controller through the LIN line and is transmitted to the four-wheel drive controller through the vehicle body controller and the CAN bus. The four-wheel drive controller responds to the switch request signal and sends an action signal (namely an action command) to a driving motor of the shifting fork so that the driving motor drives the shifting fork to move, and when the target driving mode is a four-wheel drive mode or a low-speed four-wheel drive mode, the shifting fork can drive the shaft sleeve to move so that the first long half shaft and the second long half shaft are combined; when the target driving mode is a two-wheel driving mode, the shifting fork can drive the shaft sleeve to move so as to disconnect the first long half shaft and the second long half shaft, and therefore internal consumption of the transmission system is reduced.
Meanwhile, the driving motor can transmit the position information of the shifting fork to the four-wheel drive controller through the position feedback signal, and the four-wheel drive controller can determine the position of the shifting fork according to the position feedback signal.
The four-wheel drive controller may control a power output state of the transfer case to switch the vehicle to a drive mode corresponding to the switching request signal. After the vehicle is switched to the driving mode corresponding to the switch request signal, the four-wheel drive controller CAN feed back a four-wheel drive state signal to the display instrument through the CAN bus so that the display instrument CAN display the current driving state of the vehicle. For example, if the number of times that the four-wheel drive controller sends the actuating signal to the driving motor reaches a preset number of times and the current position of the shift fork does not correspond to the target driving mode, the four-wheel drive state signal may include "mode switching = Fault", and the display instrument may correspondingly display "electric control shift fork Fault".

In this scheme, under the condition that the current position of the shift fork does not correspond to the target driving mode of the vehicle, the driving motor needs to be controlled to drive the shift fork to move to the position corresponding to the target driving mode. Therefore, an action command is sent to the driving motor to instruct the driving motor to drive the shift fork to move to a position corresponding to the target driving mode for a preset time. And after the action command is sent, if the shifting fork does not move to the position corresponding to the target driving mode of the vehicle, prolonging the preset time of the action command, and re-executing the step of sending the action command to the driving motor. Like this, can prolong the time that the motor drove the shift fork and remove, under the great condition of sliding resistance of axle sleeve, the shift fork of being convenient for drives the axle sleeve and slides, and then the shift fork of being convenient for removes to the position that corresponds with target drive mode, reduces because of the great wrong condition of wrong report that leads to of sliding resistance of axle sleeve.
