- the present invention relates to a shift determination device for a manual transmission mounted on an automobile or the like.
- the present invention relates to a measure for determining whether or not an appropriate shift operation is performed by a driver.
- a shift lever is movably disposed in a shift gate formed with a gate groove extending in a direction (sometimes referred to as a shift operation direction). Then, after a select operation that operates the shift lever in the select operation direction along the gate groove, a desired gear position is established in the transmission mechanism of the manual transmission by performing a shift operation that operates in one direction of the shift operation direction.
- the manual transmission has a feature that a shift operation to an arbitrary gear stage intended by the driver is possible. That is, it can be said that the manual transmission has a great feature that the degree of freedom in selecting the shift speed is high (the selection of the shift speed depends on the driver's intention).

Whether or not the state in which the gear position is selected by the shift operation is a state in which engagement of the clutch device 6 is allowed (a state in which the clutch device 6 and the engine 1 are not adversely affected even if the clutch device 6 is connected as it is.
- the shift determination operation in the present embodiment includes three determination conditions for determining whether the clutch device 6 is not allowed to be engaged or that the driver should be alerted when the clutch device 6 is engaged. Using conditions, a shift determination operation is performed according to these conditions.
- the warning lamp 99 is turned on. I have to. This will be specifically described below.
- FIG. 6 is a flowchart showing the procedure of the shift determination operation in the present embodiment.
- the flowchart shown in FIG. 6 is executed every several milliseconds or every predetermined rotation angle of the crankshaft 13 while the vehicle is traveling.
- step ST1 it is determined whether or not the clutch device 6 has been released. That is, it is determined whether or not the clutch mechanism portion 60 has been released by the depression operation of the pedal lever 72 by the driver. Specifically, it is determined whether or not the clutch device 6 has been released based on the output signal from the clutch switch 8B, and the clutch device 6 is in the released state when an ON signal is transmitted from the clutch switch 8B. I am trying to judge.
- step ST7 it is determined whether or not a warning flag stored in the ECU 9 in advance is ON.
- This warning flag is used when the clutch device 6 is not allowed to be engaged due to a determination condition (determination conditions of steps ST2 to ST4) described later, or when the driver should be alerted when the clutch device 6 is engaged.
- the flag is set to ON together with warning ON (the warning lamp 99 is turned on). The warning is not yet ON (the warning is not ON because the clutch device 6 is in the engaged state and the manual shift operation is not performed), and the warning flag is OFF
- NO NO is determined and the process returns.
- step ST2 the process proceeds to step ST2 to perform a first shift determination operation.
- the increase amount ⁇ Ni (input rotation speed change rate) per unit time of the rotation speed Ni of the input shaft IS detected by the input rotation speed sensor 8A is set to a predetermined change rate threshold value a. Determine if it has exceeded.
- This change rate threshold value a is the amount of increase per unit time in the rotational speed of the input shaft IS when a general driver performs a downshift operation at the operation speed when performing an upshift operation (for example, It is set as a value corresponding to the amount of increase in the rotational speed of the input shaft IS per 0.1 sec.
- the time required for the shift operation from the neutral position to the shift position that establishes the target shift speed is as follows. It is about 0.1 sec.
- the shift lever L is operated from the second gear position 2nd (see FIG. 4) to the third gear / fourth gear select position P2
- the shift lever L is moved from the third gear / fourth gear select position P2 (neutral position) to the third gear position.
- the time required for shifting to 3rd is about 0.1 sec.
- the time required for the shift operation from the neutral position to the shift position for establishing the target shift stage is about 0.3 sec. .
- the shift lever L is operated from the third gear position 3rd (see FIG. 4) to the first gear / second gear select position P1
- the shift lever L is moved from the first gear / second gear select position P1 (neutral position) to the first gear position.
- the speed required for shifting to 1st is about 0.3 sec.
- the shift operation speed is generally different between the upshift operation and the downshift operation. For this reason, when the driver intentionally performs the downshift operation, the time required until the rotational speed of the input shaft IS increases from the rotational speed before the shift to the rotational speed after the shift is about This is 0.3 sec. When converted per 0.1 sec, the rotation speed change (change rate of the rotation speed) is 1/3 of the deviation between the rotation speed before the shift and the rotation speed after the shift.
- the rotation speed of the input shaft IS shifts from the rotation speed before the shift for 0.1 sec. It will rise to a later rotational speed. It is the first shift determination operation that captures this fact and detects that a misshift has occurred. That is, when such a misshift occurs, the amount of increase ⁇ Ni per unit time of the rotational speed of the input shaft IS detected by the input rotational speed sensor 8A exceeds a predetermined change rate threshold value a.
- the specific value of the change rate threshold value a is, for example, from the second speed to the first speed at the vehicle speed (for example, 40 km / h) to be shifted from the second speed to the third speed after the vehicle starts.
- the change in the rotational speed of the input shaft IS (the amount of increase in the rotational speed) when the gear is shifted to a stage is set to a value that occurs in 0.1 sec.
- step ST2 If the amount of increase ⁇ Ni per unit time of the rotational speed Ni of the input shaft IS exceeds the predetermined change rate threshold value a, and YES is determined in step ST2, the process proceeds to step ST5, and currently a warning flag. Determines whether or not is ON. That is, it is determined whether the warning lamp 99 has already been turned on (the lighting of the warning lamp 99 has already been started in the previous routine), and accordingly, the warning flag is turned on.
- step ST5 If the warning flag is already ON, and YES is determined in step ST5, the warning flag is kept ON and the process returns. That is, the lighting of the warning lamp 99 is continued.
- step ST5 when the warning flag is OFF, that is, when the warning lamp 99 is turned off (NO in step ST5), the warning lamp 99 is turned on for the first time in the current routine by the first shift determination operation. If the condition to be satisfied is satisfied, the process proceeds to step ST6, the warning lamp 99 is turned on (warning operation to the driver by the warning means), the warning flag is set to ON, and the process returns.
- the driver recognizes that a misshift has been performed and restarts the shift operation (restarts the shift operation from the first speed to the third speed) or the clutch device 6. Therefore, the joint operation is carefully performed (the release operation is slowly performed).
- step ST2 When the amount of increase ⁇ Ni per unit time of the rotational speed of the input shaft IS does not exceed the change rate threshold value a and NO is determined in step ST2, the process proceeds to step ST3 and the second shift determination operation is performed. .
- the second shift determination operation it is determined whether or not the rotational speed Ni of the input shaft IS detected by the input rotational speed sensor 8A exceeds a predetermined rotational speed threshold value b.
- the rotation speed threshold value b is set to, for example, an upper limit value of the allowable rotation speed of the engine 1, and specifically, is 9000 rpm. This value is not limited to this. That is, it is determined whether or not the rotational speed Ni of the input shaft IS exceeds the upper limit value of the allowable rotational speed of the engine 1.
- step ST2 a downshift operation from the fifth gear to the fourth gear is erroneously performed to the second gear, and the operation speed (shift)
- the determination is NO in step ST2 and YES in step ST3.
- the upshift operation from the third speed to the fourth speed is erroneously performed and the downshift operation is performed to the second speed, and the operation speed (operation speed of the shift lever L) is relatively low.
- a NO determination is made in step ST2 and a YES determination is made in step ST3.
- step ST3 determines whether or not the warning flag is currently ON. To do. That is, it is determined whether the warning lamp 99 has already been lit and the warning flag is turned on accordingly.
- step ST5 If the warning flag has already been turned on and YES is determined in step ST5, the warning flag is kept on and the process returns. That is, the lighting of the warning lamp 99 is continued.
- step ST6 when the warning flag is OFF, that is, when the warning lamp 99 is turned off, the warning lamp 99 is turned on and the warning flag is set ON according to the second shift determination operation (step ST6).
- step ST3 If the rotational speed Ni of the input shaft IS does not exceed the rotational speed threshold value b and NO is determined in step ST3, the process proceeds to step ST4 and a third shift determination operation is performed.
- the engine rotational speed Ne calculated based on the output signal of the crank position sensor 81 is subtracted from the rotational speed Ni of the input shaft IS detected by the input rotational speed sensor 8A. It is determined whether or not the value (deviation between the input shaft rotational speed and the engine rotational speed; Ni-Ne) exceeds the rotational deviation threshold c.
- the rotation deviation threshold c is set to an upper limit value in a range that does not adversely affect the clutch device 6 such as damage, and is specifically 3000 rpm. This value is not limited to this.
- step ST2 when the downshift operation is performed from the fifth speed to the fourth speed, the release duration of the clutch device 6 is relatively long, and the engine speed is about the idling speed. If it has decreased to NO, a determination of NO is made in step ST2 and step ST3, and a determination of YES is made in step ST4. In addition, when an upshift operation is performed from the third speed to the fourth speed, the release duration of the clutch device 6 is relatively long, and the vehicle speed increases as the vehicle travels downhill ( In the case where the input rotational speed also increases), the determination is NO in step ST2 and step ST3 and YES in step ST4.
- step ST4 If the deviation between the input shaft rotational speed and the engine rotational speed exceeds the rotational deviation threshold c, and if YES is determined in step ST4, the process proceeds to step ST5, and whether or not the warning flag is currently ON. Determine whether. That is, it is determined whether the warning lamp 99 has already been lit and the warning flag is turned on accordingly.
- step ST5 If the warning flag has already been turned on and YES is determined in step ST5, the warning flag is kept on and the process returns. That is, the lighting of the warning lamp 99 is continued.
- step ST6 when the warning flag is OFF, that is, when the warning lamp 99 is turned off, the warning lamp 99 is turned on and the warning flag is set to ON according to the third shift determination operation (step ST6).
- the lighting of the warning lamp 99 causes the driver to redo the speed change operation or carefully perform the joint operation of the clutch device 6.
- step ST4 If the deviation between the input shaft rotation speed and the engine rotation speed does not exceed the predetermined rotation deviation threshold c and the determination in step ST4 is NO, the process proceeds to step ST7, and the warning flag is ON. Determine whether or not.
- step ST7 When the warning flag is ON, that is, when the warning lamp 99 is in a lighting state and YES is determined in step ST7 (when the warning lamp 99 is turned on by any shift determination operation in the past routine).
- step ST8 the warning is turned off (the warning lamp 99 is turned off), the warning flag is reset to OFF, and the process returns.
- the warning flag is not ON (NO in step ST7), the process returns as it is.
- the driver when the manual shift operation by the driver is not appropriate (when the gear is switched to a gear not intended by the driver (misshift), or when the driver intentionally performs the downshift operation). Even if the selected gear is not appropriate for the vehicle running state), the driver is warned by determining that. Therefore, by allowing the manual shift operation by the driver, while utilizing the characteristics of the manual transmission such that the degree of freedom of selection of the shift stage is high, the manual shift operation to the appropriate shift stage is promoted, or the clutch device It is possible to avoid an adverse effect on the clutch device 6 and the engine 1 by giving a warning that attention is required for the joint operation 6. In addition, drivability can be improved by mitigating shift shock.
- the first determination operation can be determined during the manual shift operation. That is, since the amount of increase ⁇ Ni per unit time of the rotational speed Ni of the input shaft IS appears in the middle of a shift (in the middle of a manual shift operation), a shift determination in the middle of this manual shift operation is possible.
- the first determination operation is executed with priority over the other determination operations, so that a countermeasure according to the determination result (in the present embodiment) In this case, the warning lamp 99 can be turned on early), and the driver can be alerted early.
- the clutch device 6 is not allowed to be engaged, and the driver should be alerted when the clutch device 6 is engaged.
- Three conditions are used as determination conditions for determining this, and a shift determination operation is performed according to these conditions.
- the deviation between the input shaft rotational speed Ni and the engine rotational speed Ne (The countermeasure when Ni-Ne) exceeds the rotation deviation threshold c is different from that of the first embodiment. Therefore, only the differences from the first embodiment will be described here.
- FIG. 7 is a flowchart showing the procedure of the shift determination operation in the present embodiment.
- the same operations as those in the flowchart shown in FIG. 6 in the first embodiment are denoted by the same step numbers, and the description thereof is omitted.
- step ST4 if the deviation (Ni-Ne) between the input shaft rotational speed Ni and the engine rotational speed Ne exceeds a predetermined rotational deviation threshold c, YES is determined.
- engine speed increase control is executed. This engine speed increase control is performed so as to increase the opening of the throttle valve 33 by the control of the throttle motor 34, thereby increasing the engine speed (driving by the speed increase control means). Source speed increase control).
- the engine speed is increased so that the deviation (Ni-Ne) between the input shaft rotational speed Ni and the engine rotational speed Ne is equal to or less than the rotational deviation threshold c.
- the target value of the deviation (Ni ⁇ Ne) is set to the above value.
- the engine speed is controlled as the rotation deviation threshold c. That is, when the rotation deviation threshold c is set to 3000 rpm, when the input shaft rotational speed Ni is 5500 rpm and the engine rotational speed Ne is 2300 rpm (when the rotational speed difference is 3200 rpm), the engine rotational speed Ne.
- the degree of opening of the throttle valve 33 is corrected so as to increase by 200 rpm.
- the opening correction operation of the throttle valve 33 is performed according to a throttle valve opening correction map stored in advance in the ROM 92, for example.
- FIG. 8 shows an example of the throttle valve opening correction map.
- step ST7 it is determined whether or not the warning flag is ON. That is, it is determined whether or not the warning flag is ON (whether or not the warning lamp 99 is in a lit state) because YES is determined in step ST2 or ST3 in the past routine. If the warning flag is OFF, NO is determined in step ST7 and the process returns. In this case, even if the deviation (Ni ⁇ Ne) between the input shaft rotational speed Ni and the engine rotational speed Ne temporarily exceeds the rotational deviation threshold c, the clutch device 6 is not turned on without the warning lamp 99 being lit. Will be properly joined.
- step ST8 if the warning flag is ON, that is, if the warning lamp 99 is in a lit state and YES is determined in step ST7, the process proceeds to step ST8, where the warning is turned off (the warning lamp 99 is turned off). Reset the warning flag to OFF and return.
- the warning lamp 99 is turned on when YES is determined in step ST2 or ST3 in the past routine, and then the warning lamp 99 is turned off as the input shaft rotational speed Ni decreases.
- the present embodiment it is possible to achieve the same effects as in the case of the first embodiment described above.
- the third shift determination operation when the deviation (Ni ⁇ Ne) between the input shaft rotational speed Ni and the engine rotational speed Ne exceeds a predetermined rotational deviation threshold c, The engine speed increase control is being executed. That is, it is possible to obtain a situation in which the clutch device 6 is allowed to be joined without issuing a warning to the driver. For this reason, it is possible to allow the clutch device 6 to be connected while protecting the clutch device 6 without causing the driver to feel uncomfortable (a sense of incongruity of receiving a warning).
- the warning lamp 99 is turned on when the driver should be alerted when the clutch device 6 is engaged.
- the present invention is not limited to this, and the warning lamp 99 may be blinked, or the driver may be alerted by sound such as a warning buzzer, or the warning lamp 99 and the warning buzzer may be used in combination. It may be.
- the present invention is not limited to this, and can also be applied to a vehicle equipped with a diesel engine or a hybrid vehicle equipped with an engine (internal combustion engine) and an electric motor (for example, a traveling motor or a motor generator).
- the clutch switch 8B is used as a sensor for determining whether or not the clutch device 6 is released.
- the present invention is not limited to this, and a clutch stroke sensor that can detect the position of the clutch pedal 70 and a stroke sensor that can detect the slide position of the release bearing 67 can also be employed.
- the present invention can be applied to a manual transmission that can determine whether or not an appropriate shift operation has been performed by a driver and issue a warning to optimize the shift operation.

Abstract
Description
(1)例えば車両が発進して加速していく状況においては、運転者は比較的早い操作速度でシフトレバーを操作しながらアップシフトしていくことになるが、この際に、ミスシフトが生じてダウンシフト側の変速段が選択されてしまうと、クラッチ継合時に過大な減速トルクがクラッチ装置に入力され、クラッチ装置に悪影響を与えたり、大きな変速ショック(減速側の変速ショック)が発生したりする可能性がある。
(2)車両の走行速度が比較的高い状況で意図的にダウンシフト操作を行った場合、この走行速度に対してダウンシフト後の変速段の変速比が大きすぎると、クラッチ継合時にエンジン回転数が急上昇し許容回転数を超えてしまう可能性がある。
(3)車両の走行速度が比較的高い状況で意図的にダウンシフト操作を行った場合に、エンジン回転数が比較的低くなった状況(例えば、クラッチ解放状態の継続時間が長い場合)でクラッチ継合操作を行った場合にも、クラッチ継合時に過大な減速トルクがクラッチ装置に入力され、クラッチ装置に悪影響を与える可能性がある。
上記の目的を達成するために講じられた本発明の解決原理は、運転者のミスシフトや、意図的なダウンシフト操作であってもそれが適正でない場合には、そのことを手動変速機の入力軸回転数の変化等に基づいて判定し、運転者への警告や、駆動源の制御によって、ミスシフト状態や不適正な変速段成立状態でのクラッチ装置の継合が回避できるようにしている。
具体的に、本発明は、クラッチ装置の継合及び解放に伴って駆動源からの駆動力の伝達及び遮断が行われると共に、上記クラッチ装置が解放された状態での運転者による手動シフト操作によって、複数の変速段のうち何れかが選択可能とされた手動変速機のシフト判定装置を対象とする。この手動変速機のシフト判定装置に対し、上記クラッチ装置が解放された状態での運転者による手動シフト操作に伴って変化する上記手動変速機の入力軸回転数に基づき、この手動シフト操作により変速段が選択された状態が、クラッチ装置の継合を許容する状態であるか否か、または、クラッチ装置の継合に際して運転者に注意を促すべき状態であるか否かを判定するシフト判定手段を備えさせている。

次に、本実施形態の特徴とする動作であるシフト判定動作について説明する。このシフト判定動作は、運転者による手動シフト操作が、適切な変速段を選択したものであるか否かを判定する(ミスシフトであるか否かの判定を含む)ために行われる。具体的には、上記クラッチ装置6が解放された状態(クラッチペダル70が踏み込まれた状態)において、運転者による手動シフト操作に伴って変化する上記インプットシャフトISの回転数Niに基づき、この手動シフト操作により変速段が選択された状態が、クラッチ装置6の継合を許容できる状態であるか否か(そのままクラッチ装置6を継合してもクラッチ装置6やエンジン1に悪影響を与えない状態であるか否か)、または、クラッチ装置6の継合に際して運転者に注意を促すべき状態であるか否か(そのままクラッチ装置6を継合させる場合には、その継合速度や継合タイミングに注意すべき状態であるか否か)を判定するようにしている(シフト判定手段によるシフト判定動作)。そして、クラッチ装置6の継合を許容できる状態でない場合や、クラッチ装置6の継合に際して運転者に注意を促すべき状態である場合には、それに応じた制御動作(上記警告ランプ99の点灯や、エンジン1の制御など)を行うようにしている。以下、このシフト判定動作及びその判定結果に応じた制御動作についての複数の実施形態を説明する。
先ず、第1実施形態について説明する。
次に、第2実施形態について説明する。
