Description

Technical Field

[0001] This invention relates to the field of vehicle shift hub control, and more specifically, to a method, apparatus, and electronic device for confirming the rotation path of a shift hub. Background Technology

[0002] The shift hub is a common transmission mechanism in vehicle gearboxes. The shift hub has shift grooves carved into its annular outer wall, and shift forks are mounted between the two side walls within these grooves. When the shift hub rotates, an axial torque is applied to the shift forks through the inclined surfaces of the shift grooves, causing the shift forks to move axially along the shift hub, thereby driving the synchronizer to engage or disengage gears.

[0003] like Figure 1-2 As shown, the working range of the shift hub is generally limited to 360°. To physically limit the rotation angle of the shift hub 1, an end face boss 2 is provided on the end face of the shift hub 1. When the shift hub 1 rotates clockwise, it stops rotating because its end face boss 2 touches the locking boss 3 at the end of the housing 4. This position of the shift hub is called the top dead center 5, also known as the initial position of the shift hub. When the shift hub 1 rotates counterclockwise, its end face boss 2 will eventually touch the other side of the locking boss 3, at which point it reaches the bottom dead center 6 of the shift position.

[0004] Shift hub angle control refers to ensuring that the shift hub moves from its current angular position along the shortest rotation path to the target angular position without passing through a prohibited rotation area. In conventional control, when the shift hub does not have a prohibited rotation area, it often does not reach the target angular position along the shortest path; when the shift hub has a prohibited rotation area, it does not bypass the prohibited area and needs to change the rotation direction to find the target angular position again. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a method, device and electronic device for confirming the rotation path of the shift hub, so that the shift hub can reach the target angle position efficiently and quickly.

[0006] The technical solution adopted by this invention to solve its technical problem is: constructing a method for confirming the rotation path of a gear shift hub, comprising:

[0007] The angle of the restricted rotation zone of the shift hub is determined based on the top dead center angle and the bottom dead center angle of the shift hub.

[0008] Determine whether the current and target angle positions of the shift hub are outside the prohibited rotation angle range;

[0009] If both the current and target angle positions of the shift hub are outside the prohibited rotation area, the rotation angles from the current angle position to the target angle position and from the current angle position to the bottom dead center position are calculated respectively. The rotation path of the shift hub is determined based on the two rotation angles.

[0010] According to the above scheme, in the method of determining the restricted rotation area angle range of the shift hub based on the top dead center angle and bottom dead center angle of the shift hub, the area where the shift hub rotates counterclockwise from the top dead center angle to the bottom dead center angle is obtained, which is the rotational active area angle; the area where the shift hub rotates counterclockwise from the bottom dead center angle to the top dead center angle is obtained, which is the restricted rotation area angle; and the rotational active area angle... and the angle of the prohibited rotation area The following relationship must be satisfied:

[0017] If the current angle position is rotated counterclockwise to the top dead center angle by an angle less than the angle of the prohibited rotation area, then the current angle position is within the range of the prohibited rotation area angle.

[0018] According to the above scheme, the methods for determining whether the target angle position of the shift hub is outside the prohibited rotation area angle range include:

[0019] If the target angle position is rotated counterclockwise to the top dead center angle by an angle greater than or equal to the angle of the prohibited rotation area, then the target angle position is outside the angle range of the prohibited rotation area.

[0020] ​If the target angle position is rotated counterclockwise to the top dead center angle by an angle less than the angle of the prohibited rotation area, then the target angle position is within the range of the prohibited rotation area angle.

[0024] Get the current position A from the current angle start Rotate counterclockwise to the bottom stop A down rotation angle If A down ≥A start ,but If A down start ,but

[0045] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0046] Example 1

[0047] like Figure 3-4 As shown, the method for confirming the rotation path of the shift hub in this invention includes:

[0048] S1. Determine the restricted rotation zone angle of the shift hub based on its top dead center (TDC) and bottom dead center (BDC) angles. After receiving the target angle command, the shift hub actuator, such as a shift motor, must select the optimal rotation path based on the current gear and the restricted rotation zone to ensure the shift hub quickly reaches the target angle. The optimal rotation path is represented by a signed angle value, the magnitude of which represents the angle difference between the current angle and the target angle. The direction of the angle value is defined as counter-clockwise (positive) and clockwise (negative). The direction of the shift hub's rotation from the initial TDC to the BDC is counter-clockwise.

[0049] If the shift hub can rotate freely more than one revolution, it indicates that the shift hub does not have a restricted rotation angle. If there is a boss on the end face of the shift hub and a corresponding blocking boss on the housing, then the shift hub has a restricted rotation angle due to blocking.

[0051] If A up >A down ,but

[0053] If A up =A down ,but This indicates that the shift hub does not have a restricted rotation angle;

[0054] according to and As can be seen from the definition,

[0060] Then determine if the current angle and position are valid:

[0061] if This means that the current angle position is outside the prohibited rotation area and is therefore valid.

[0062] Conversely if This indicates that the current angle position is within the prohibited rotation area, and the current angle position is invalid. (Shift hub rotation path) This is an invalid value. ​​

[0066] If A up end ,but

[0067] Then determine if the target angle is valid:

[0068] if This indicates that the target angle is outside the rotation restricted area, and the current angle is valid;

[0069] Conversely if This indicates that the target angle is within the rotation restricted area, and the current angle is invalid. (Shift hub rotation path) This is an invalid value.

[0070] S3. If both the current and target angle positions of the shift hub are outside the prohibited rotation area, calculate the counterclockwise rotation angle from the current position to the target position, and the counterclockwise rotation angle from the current position to the bottom dead center position. Determine the shift hub rotation path based on these two rotation angles, including the following steps:

[0071] S301, Obtain the current angle position A start Rotate counterclockwise to target angle position A end rotation angle If A end ≥A start ,but If A end start ,but

[0072] S302, Obtain the current angle position A start Rotate counterclockwise to the bottom stop A down rotation angle If A down ≥A start ,but If A down start ,but ​​​

[0073] S303, Based on the rotation angle and rotation angle The size determines the rotation path of the shift hub:

[0074] if The rotation path of the shift hub

[0075] if The rotation path of the shift hub

[0076] Furthermore, when the top dead center angle and the bottom dead center angle are the same, there is no restricted rotation angle for the shift drum. The method for confirming the rotation path of the shift drum includes:

[0077] Get the current position A from the current angle start Rotate counterclockwise to target angle position A end rotation angle If A end ≥A start ,but If A end start ,but

[0078] According to the rotation angle Calculate the size of the gear shift hub rotation path if but if but
