Definitions
- the present invention relates to a control device for an automatic transmission, and more particularly to a control device for an automatic transmission that transmits a driving force to wheels by a one-way clutch.
- Japanese Patent Application Laid-Open No. 2-1 29 4 5 4 discloses a lubrication device for a one-way clutch capable of forcibly lubricating a one-way clutch.
- This one-way clutch lubrication device includes a case support wall extending inward from the inner peripheral surface of the case, a one-way clutch disposed adjacent to the case support wall, an inner peripheral surface of the inner race of the one-way clutch, and a case support
- a one-way clutch in an automatic transmission that includes a cylindrical member that is commonly fitted to the inner peripheral surface of the wall and that rotatably supports the rotating member on the inner peripheral side is lubricated.
- a spline is formed on the outer peripheral surface of the cylindrical member to form a first spline connecting portion between the inner peripheral surface of the case support wall and a second spline connecting portion between the inner peripheral surface of the inner race.
- a lubricating oil supply hole that opens to the first spline joint is formed in the case support wall.
- An oil hole that penetrates the inner race in the radial direction and opens to the second spline joint is formed in the inner race.
- Sealing portions are provided outside the opening in the first spline coupling portion, outside the opening in the second spline coupling portion, and between the case support wall and the inner race side surface, and are connected to the first spline from the lubricating oil supply hole.
- a lubricating oil path is formed that reaches the sliding portion of the one-way clutch through the coupling portion, the second spline coupling portion, and the oil hole.
- the lubricating oil from the lubricating oil supply hole is a first spline between the inner peripheral surface of the case support wall and the outer peripheral surface of the cylindrical member.
- a second spline between the inner peripheral surface of the inner race and the outer peripheral surface of the tubular member, through an oil hole that penetrates the inner race in the radial direction, Supplied to the sliding part of the clutch. That is, the lubricating oil supply hole, the first spline, the second spline, and the oil hole form a lubricating oil path for lubricating the one-way clutch.
- the lubricating oil passage is sealed by the sealing portion, and the lubricating oil does not leak in the middle of the lubricating oil passage. Therefore, the lubricating oil supplied from the lubricating oil supply hole is forcibly supplied to the sliding portion of the one-way clutch without depending on the centrifugal force or the like. As a result, the one-way clutch can always be reliably lubricated with a sufficient amount of lubricating oil, and the durability and reliability of the one-way clutch can be greatly improved.
- the one-way clutch used in automatic transmissions restricts the rotation of the outer race and inner race (becomes engaged) when the first gear is driven (running by the driving force of the vehicle)
- some are configured to allow rotation (become disengaged). This is to suppress the deterioration of driveability due to engine braking at the first gear.
- the vehicle travels on a road surface that undulates, for example, the vehicle can vibrate up and down, so that the wheels can be repeatedly separated from the road surface or grounded.
- the one-way latch repeatedly allows or restricts rotation of the outer race and inner race.
- An object of the present invention is to provide an automatic transmission control device capable of suppressing damage to a one-way clutch.
- the control device for an automatic transmission provides a method for rotating the outer ring and the inner ring.
- the automatic transmission that transmits the driving force to the wheels is controlled by a limiting member that permits the direction and limits the reverse direction.
- This control device is connected to the outer ring and the inner ring, and includes a suppression unit that suppresses a difference in rotational speed between the outer ring and the inner ring, a detection unit that detects the state of the limiting member, and a predetermined condition regarding the state of the limiting member. And a control unit that controls the suppression unit so as to suppress a difference in rotational speed between the outer ring and the inner ring.
- the driving force is transmitted to the wheel by the limiting member (for example, a one-way clutch).
- the state of this restricting member (for example, the rotational state of the outer ring and the inner ring) is detected. If the rotation of the outer ring and the inner ring is repeatedly allowed or restricted, pobbing may occur and the one-way clutch may be damaged. In addition, if the rotation of the outer ring and the inner ring is suddenly shifted from a permitted state to a restricted state, the one-way clutch may be damaged. Therefore, it is a state in which the rotation of the outer ring and the inner ring can be allowed or restricted repeatedly, or the state in which the rotation of the outer ring and the inner ring can be repeated from a permitted state to a restricted state.
- the suppression unit is controlled to suppress the rotation of the outer ring and the inner ring.
- the outer ring is fixed to the casing of the automatic transmission.
- the inner ring is connected to the rotating shaft of the automatic transmission.
- the suppressing portion is a friction engagement element that is provided by hydraulic pressure and is provided between the housing and the rotation shaft so as to be connected to the restriction member via the housing and the rotation shaft.
- the control unit controls the friction engagement element so that the friction engagement element is in the engaged state.
- the state where the rotation of the outer ring and the inner ring can be permitted or restricted repeatedly, or the state where the rotation of the outer ring and the inner ring is permitted, is suddenly shifted to a restricted state.
- the friction engagement element is brought into an engagement state.
- the state of the limiting member is a rotation state between the outer ring and the inner ring.
- the control device further includes a rotation speed detection unit that detects the rotation speed of the output shaft of the automatic transmission.
- the detecting unit detects the rotational state of the outer ring and the inner ring based on the rate of change in the rotational speed of the output shaft. The condition is that the rate of change of the rotation speed of the output shaft is larger than a predetermined rate of change.
- the rotational speed of the output shaft of the automatic transmission is detected.
- the rate of change of the output shaft rotation speed is large, the wheel repeatedly leaves the road surface or touches the ground, so the load on the automatic transmission via the wheel increases and decreases in a short cycle. In this case, it can be repeated that the rotation of the outer ring and the inner ring is allowed or restricted. For this reason, when the condition that the rate of change in the rotational speed of the output shaft is large is satisfied, the rotation of the outer ring and the inner ring is suppressed. As a result, the occurrence of pobbing can be suppressed.
- control device further includes an estimation unit that estimates the rotation speed of the output shaft of the automatic transmission, and a rotation speed detection unit that detects the rotation speed of the output shaft of the automatic transmission.
- the detection unit detects the rotational state of the outer ring and the inner ring based on the difference between the estimated rotational speed and the detected rotational speed. The condition is that the difference in rotational speed is larger than a predetermined value.
- the rotational speed of the output shaft of the automatic transmission is estimated.
- the output shaft speed can be estimated by dividing the input shaft speed by the gear ratio.
- the rotation speed of the output shaft is detected.
- pobbing may occur in the restricting member. Therefore, when the condition that the difference in rotational speed is larger than a predetermined value is satisfied, the rotation between the outer ring and the inner ring is suppressed. As a result, the occurrence of pobbing can be suppressed.
- control device further includes a selection unit that selects a control mode of the automatic transmission by the operation of the occupant.
- the detection unit detects the rotation state of the outer ring and the inner ring based on the operation state of the selection unit. The condition is that the selection unit has been operated by a passenger.
- the occupant operates the selection unit (for example, shift lever).
- the control mode for example, shift range
- the shift lever is operated from “P position” to “D position”
- the driving force of the power source is transmitted to the wheels via the automatic transmission.
- the rotation of the outer ring and the inner ring can be abruptly limited. Therefore, when the condition that the selection unit is operated by the occupant is satisfied, rotation of the outer ring and the inner ring is suppressed. Thereby, it is possible to prevent the rotation of the outer ring and the inner ring from being restricted suddenly.
- the limiting member is a one-way clutch.
