Description

Technical Field [0001] The present invention relates to a method of initializing a gear actuator position of an automatic manual transmission,

[0001] The present invention relates to a method for initializing a gear actuator position of an automatic manual transmission, and more particularly, to an automatic manual transmission in which an automatic manual transmission is provided with a shift motor and a selector motor for driving the shift lugs of the transmission, The present invention relates to a method of initializing a gear actuator position of an automatic manual transmission that is initialized when a gear actuator is assembled.

In general, an automatic manual transmission (AMT) is a device that implements an automatic transmission function by automating the shifting operation of a manual transmission by using power that the driver operates the shift lever by hand, It has all the convenience of an automatic transmission while maintaining the advantages of fuel economy.

Research is being actively carried out to improve fuel efficiency and environmentally friendly automobiles worldwide. Transmissions are also a trend to replace conventional manual transmissions with automated manual transmissions and dual clutch transmissions instead of automatic transmissions to improve fuel economy. To automate these manual transmissions, an actuator for shifting gears is required, and most of the actuators are made up of motors

The automatic manual transmission shifts the finger to move the shift lug along the shift or select direction with the gear actuator. The gear actuator includes a select motor for select operation and a shift motor for seat operation have.

1, the select motor moves the finger 10 along the select direction on the neutral positions N1, N2, N3, and N4 to move the finger 10 in any one of the neutral positions N1, N2, N3, and N4 And the shift motor performs a selecting operation to select one of the speed change lugs 1, 2, 3, 4, 5, 6, and R, and the shift motor performs the selecting operation at the neutral position selected by the select operation of the select motor ) Is shifted along the shift direction, so that the finger 10 pushes the shift lug to effect shifting.

Here, when the finger 10 is positioned between two neutral positions other than one of the neutral positions N1, N2, N3, and N4 by the select operation of the select motor, the two shift lugs are pushed simultaneously.

On the other hand, when the position value of the shift motor is set incorrectly in the shift operation, the shift is less than the original gear engagement position and the shifting is not performed properly, or the shift motor is moved more than the original gear engagement position and the shift motor is overloaded.

In order to solve these problems, the position of the finger must be properly set when assembling the shift motor and the select motor to the transmission, and the initial position values of the shift motor and the select motor for controlling the moving distance of the finger must be properly set.

However, due to the accumulation of the mechanical tolerance in the structure of the manual transmission and the assembly tolerance, the position of the finger after assembling is different from the design value. When the set position value of the shift motor and the select motor is applied as it is, The shift operation can not be performed properly.

The present invention has been made in order to solve the problems of the gear actuator position initialization method of the conventional automatic manual transmission as described above, and it is possible to provide a gear actuator, which is suitable for shifting during the assembly of the transmission and the gear actuator, And an object of the present invention is to provide a method of initializing a gear actuator position of an automatic manual transmission in which the transmission quality of a manual transmission can be improved.

In order to achieve the above object, a method for initializing a position of a gear actuator of an automatic manual transmission according to the present invention includes shifting a finger from a neutral position to a shift position in a shifting direction by driving a shift motor (S11) (S12). The position of the select motor is detected when the load reaches the one end of the finger in the select direction movement path and the load of the select motor is increased. (S13). The finger is moved to the opposite side along the select direction by applying a constant counter load to the select motor at the shift position of the step S13 (S14), and the finger reaches the opposite end on the select direction movement path, (Step S15) of detecting the position value of the select motor when the step S13 and step S13 And a step (S16) of averaging the two position values at both ends of the shift position detected in step S15 and setting the average position value to the select direction neutral position value at the shift position.

In the gear actuator position initializing method of the automatic manual transmission according to the embodiment of the present invention, the difference between the position values at the two adjacent speed change stages in the select direction among the select direction neutral position values calculated at step S16, Position can be set to the position value of the select motor for moving between the two speed change stages along the select direction.

In order to achieve the above object, a method for initializing a position of a gear actuator of an automatic manual transmission according to the present invention is a method for shifting a finger in a shift direction by applying a constant load to a shift motor at a neutral position of a gear, Detecting a position value of the shift motor when the load of the shift motor reaches one end of the shift motor by increasing the load of the shift motor by a predetermined constant load on the shift motor at the position of step S21, (S22) of detecting the position value of the shift motor when the load of the shift motor increases when the finger reaches the opposite end of the shift motor when the finger reaches the opposite end of the shift motor and the two position values of the shift motor detected in the steps S21 and S22 And setting the average position value to a neutral position in the shift direction (S23). It is gong.

The features and advantages of the present invention will become more apparent from the following detailed description based on the accompanying drawings.

As described above, according to the method of initializing the position of the gear actuator of the automatic manual transmission according to the present invention, the position of the finger suitable for shifting during assembly of the transmission and the gear actuator is learned and initialized in the gear actuator, thereby improving the shift quality of the automatic manual transmission There is an effect that it is possible to prevent the two shift lugs from being pushed simultaneously or moving more than the original gear engagement position and the overload being generated in the gear actuator.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 1, the finger 10 moves in the shift direction A-B by driving the shift motor and moves in the select direction C-D by the select motor to push the shift lugs.

Reference numeral 1 denotes a speed change lug for a 1-speed shift, 2 denotes a 2-speed lug, 3 denotes a 3-speed lug, 4 denotes a 4-speed lug, 5 denotes a 5-speed lug, 6 denotes a 6-speed lug, It is a shift lug for backward movement.

Fig. 2 shows the path through which the fingers 10 move to actuate the shift lugs of Fig. Reference numerals 1 to 6 and R denote the respective shift positions at each stage, and N1, N2, N3 and N4 denote respective neutral positions.

1 to 7, a method of setting the neutral position in the select direction among the gear actuator position initializing methods of the automatic manual transmission according to the embodiment of the present invention will be described.

First, the shift motor is driven to move the finger 10 from the neutral position N1, N2, N3, N4 to the shift position R, 1,2,3,4,5,6 along the shift direction AB (S11).

For example, the finger 10 is moved from the neutral position N2 to the second shift position 2 as shown in Fig. At this time, the load applied to the shift motor is a value smaller than the load for the finger 10 to reach the end of the 2-speed shift position 2. This is because the finger 10 is spaced apart from the end of the 2- So that it is possible to move in the selecting direction. If the finger 10 comes into contact with the end of the 2-speed shifting position 2, it is difficult to detect the load of the shift motor even if the finger 10 is moved in the selecting direction due to friction, .

A certain load is applied to the select motor at the shift position of step S11 and the finger 10 is moved until it reaches one end of the select direction movement path. 4, in the example of step S11, the finger 10 is moved in the C-select direction in a state where the finger 10 is positioned in the 2-speed shift position 2 and is brought into contact with one end of the 2-speed shift position 2 (S12). Here, the select direction movement path means a straight line section in which the fingers 10 can move along the C-D select direction in the two-speed shift position (2). At this time, the load applied to the select motor is the same load as when the actual gear is shifted.

When the finger 10 reaches one end of the shift path in the select direction (CD) in the second shift position (2), the finger 10 is no longer moved and the load of the select motor is increased. And the position value of the motor is detected (S13).

An opposite load is applied to the select motor at the shift position of step S13 to move the finger 10 in the opposite direction along the select direction C-D. 5, in the example of step S13, the finger 10 is moved in the D select direction in a state where it is positioned at one end of the two-speed shift position 2, and is moved to the opposite end of the two-speed shift position 2 (S14).

When the finger 10 reaches the opposite end on the select direction movement path in the 2-speed shift position 2, the finger 10 is stopped and the load of the select motor is increased and the position value of the select motor at this time is detected (S15).

Here, when the load of the select motor is increased, since the current is continuously applied to the select motor, the life of the motor may be shortened. Therefore, when the load increases and then decreases by a predetermined load, it is desirable to detect the position value of the select motor in a zero load state in which the load is removed, for example. When a predetermined time elapses after a load is applied to the select motor, the load is reduced to zero.

If the position value of the select motor is detected in a state where the load of the select motor is increased, it is preferable to set the position reduced by the predetermined shift distance with respect to the learning value to the control position in the actual shift mode.

The two position values at both ends of the shift position detected in steps S13 and S15 are averaged and the average position value is set as the neutral position value in the select direction at the shift position (S16). For example, the position value of the select motor detected at one end of the C-select direction in the two-speed shift position (2) and the position value detected at the other end in the D-select direction are averaged to determine the neutral position Value.

Assuming that the initial position of the finger 10 at the time of assembling the transmission and the gear actuator is N2, the neutral position value in the selection direction in the two-speed shifting position 2 set in the step S16 is set to the other shifting position As shown in Fig.

On the other hand, after calculating the position value of the select motor in the 2-speed shifting position 2, the shift motor is driven to move the finger 10 to the 1-speed shifting position 1 as shown in Figs. 6 and 7 By performing steps S12 to S15, it is possible to obtain the neutral position value in the select direction in the 1-speed shift position (1).

Here, the neutral position value in the select direction calculated in the 1-speed shift position (1) and the value set in the 2-speed shift position (2) should theoretically be the same, but a difference may occur due to machining error or measurement error. It is possible to set any one of the two values as the set value, but it is preferable to set the two values again as the average value.

After setting the position value of the select motor in the 1-speed and 2-speed shifting position (2), the shift motor is driven to restore the finger 10 to the N2 neutral position. Then, To move the finger 10 to the N3 neutral position.

By performing the steps S11 to S16 at the N3 neutral position, it is possible to obtain the neutral position value in the select direction in the 4-speed shift position 4 and the 3-speed position 3.

Likewise, the shift motor is driven to move the finger 10 to the N4 neutral position, and then the steps S11 to S16 are performed to determine the neutral position position in the select direction in the five-speed shift position 5 and the six- . In addition, by performing steps S11 to S16 at the N1 neutral position, it is possible to obtain the select neutral position value at the R-speed change position (R).

Here, a, it is the finger 10, the difference value (P 24) obtained in the select position of the motor and N3 neutral position obtained in N2 neutral position as shown in Figure 8 is to move from N2 neutral position to N3 neutral position Is set to the position value to be applied to the select motor.

The difference in position values in the two gear positions adjacent to each other in the select direction among the select direction neutral position values calculated in the respective neutral positions N1, N2, N3 and N4 (for example, in the second and fourth stages) It is possible to set the position value of the select motor for moving between the two speed change stages along the select direction at the neutral position.

Any two of the gear range, for example, two stages when calculating the Select difference between the motor position value of between 4 However, the difference between the position value (P 24) is a select motor finger in the section (between the neutral position N2 and N3) (10) in the select direction.

That is, the finger 10 is in a state located in the N2, the second end when the four-stage is applied to the difference value of the select motor position value between (P 24) the select motor to the finger movement N3 by the difference value.

Therefore, when the gear is to be shifted from the first or second stage to the R-stage, the select motor is driven by the difference value P R1 obtained at the neutral position in the select direction obtained at the neutral position N1 and the neutral position If you want to shift the gears in the stage or two-stage to three-stage or four-stage, select direction neutral position and that of the difference value obtained from the N3 neutral position obtained in N2 neutral position (P 24) the select motor, and driven by, 3 If the gear is to be shifted to the 5th or 6th stage from the 4th stage to the 5th stage, the select motor is driven by the difference value ( P46 ) obtained at the neutral position in the select direction obtained at the N3 neutral position and its difference value obtained at the N4 neutral position.

As a result, P R1 , P 24 , and P 46 are the amount of positional value change of the select motor required for the finger 10 to move by one speed change stage along the select direction. Since P R1 , P 24 and P 46 may be the same value or may be different values , it is also possible to apply P R1 , P 24 and P 46 respectively. It is also possible to use the unit position value as a unit position value.

Referring to FIG. 9, a method of setting the neutral position in the shift direction among the gear actuator position initializing method of the automatic manual transmission according to the embodiment of the present invention will be described.

First, a constant load is applied to the shift motor at the neutral position of the gear to move the finger 10 in the A shift direction (S21). For example, as shown in Fig. 9, the shift motor is driven to move the finger 10 from the N2 neutral position to the 2-speed shifting position 2.

When the finger 10 reaches one end on the A shift direction movement path in step S21, when the finger 10 moves along the A shift direction at the two-speed shift position and reaches the one end, And the position value of the shift motor at that time is detected (S22).

A constant counter load is applied to the shift motor at the position of step S22 to move the finger 10 in the opposite direction (B shift direction) beyond the neutral position of the gear (S23). For example, the shift motor is driven to move the finger 10 to the one-speed shifting position 1.

When the finger 10 reaches the end in the shift direction at the one-stage shift position (1) in step S23, the load of the shift motor is increased, and the position value of the shift motor at that time is detected (S24).

Here, as in the case of the select motor, when the load of the shift motor is increased, since the current is continuously applied to the shift motor, the life of the motor may be shortened. Therefore, when the load increases and then decreases by a predetermined load, it is desirable to detect the position value of the shift motor in a zero load state where the load is removed, for example. The load is reduced to zero when a predetermined time elapses after a load is applied to the shift motor.

If the position value of the shift motor is detected in a state where the load of the shift motor is increased, it is preferable to set the position reduced by the predetermined shift distance with respect to the learning value to the control position in the actual shift mode.

The two position values of the shift motor detected in steps S22 and S24 are averaged, and the average position value is set to the neutral position in the shift direction (S25).

The steps S21 to S25 may be performed in N3 and N4, and it is preferable that the shift direction neutral position values obtained in the process are averaged and used as the final neutral position value of the shift motor.

In this way, the neutral position of the finger 10 in the shift direction can be initialized in accordance with the shift position of the shift motor in the step S21 to the step S25. In this initial position, the steps S11 to S16 are performed So that the select initialization can be performed. It goes without saying that the steps S11 to S16 may be performed first and the steps S21 to S25 may be performed.

When the shift or position movement takes longer than a predetermined time, the warning signal is regarded as having failed in time out and the warning signal is output to the outside. When the position sensor of the selector motor or the shift motor reaches a predetermined time When the sensor voltage changes within a predetermined period of time (for example, a predetermined time period), a warning signal is output to the outside.

The position values of the select motor and the shift motor can be obtained by integrating the motor speed detection value of the motor speed detection signal. Detecting and inputting the position value of the motor corresponds to a well-known technology in general.
