摘要:
A deceleration control apparatus for controlling a deceleration value of a vehicle, including a plurality of deceleration-value setting devices, a target-deceleration-value control portion operable to change a target deceleration value of the vehicle according to an operation of each of the deceleration-value setting devices, and a brake control portion operable to control a braking force to be applied to the vehicle, according to the target deceleration value changed by the target-deceleration-value control portion, wherein the target-deceleration-value control portion is operable to successively change the target deceleration value of the vehicle in response to successive operations of one and another of the plurality of deceleration-value setting devices such that the target deceleration value changed according to the operation of the above-indicated one deceleration-value setting device is subsequently changed according to the operation of the above-indicated another deceleration-value setting device.

摘要:
A target deceleration of a vehicle is increased or decreased under given conditions and braking force is controlled in accordance with the increased or decreased target deceleration. Upon the increase or decrease in the target deceleration, the rate of change in the target deceleration is variably set.
摘要:
A control apparatus for controlling a stepped automatic transmission of a vehicle having an output shaft and an input shaft which is to be connected to an engine of the vehicle through a clutch while a shifting action is being effected in the transmission. The control apparatus includes a torque vibration restrainer operable, upon completion of the shifting action in the transmission, to restrain a torque vibration which is generated in a power transmitting path of the vehicle. The torque vibration restrainer applies an inverted-phase torque vibration which is inverted in phase with respect to the generated torque vibration, to the power transmitting path, and/or place the clutch in its slipping state or released state, for restraining the generated torque vibration.
摘要:
In a hydraulic servo for a clutch, a cancel plate is disposed on a second clutch drum that undergoes the same rotation as a second clutch drum provided with a cylinder portion, in such a fashion that the cancel plate is restricted from moving to a side opposite from a return spring in an axial direction. The first clutch drum is disposed, as a separate member, on the second clutch drum. A step portion of the second clutch drum prevents the first clutch drum from moving to a side opposite from the cancel plate. Due to the spring force of the return spring, the oil pressure in the cancel oil chamber and the oil pressure in the operating oil chamber, the force that presses the first clutch drum to the step portion is always greater than the force that presses the first clutch drum to the cancel plate side.

At a first forward speed, the oil passage in a relay valve is switched to control the torque capacity of a lock-up clutch using a linear solenoid valve that controls the engagement pressure of a clutch that is engaged at each of fifth to eighth forward speeds. At each of second to eighth forward speeds, the oil passage in another relay valve is switched to control the torque capacity of the lock-up clutch using a linear solenoid valve that controls the engagement pressure of a brake that is engaged at the first forward speed.

A transmission can be provided which achieves multiple speeds while maintaining good balance of gear ratio steps between gears by having a first clutch which selectively connects a first intermediate output member and a fourth rotating element RE4 together, a second clutch which selectively connects an input shaft and a second rotating element RE2 together, a third clutch which selectively connects the first intermediate output member and a first rotating element RE1 together, a fourth clutch which selectively connects the input shaft and the first rotating element RE1 together, a fifth clutch which selectively connects a second intermediate output member and the first rotating element RE1 together, a first brake which selectively holds the first rotating element RE1 to a transmission case, and a second brake which selectively holds the second rotating element RE2 to the transmission case.
摘要:
Engagement, disengagement, and slip of a lock-up clutch can be controlled using two valves that are a lock-up relay valve and a linear solenoid valve. A lock-up control valve employed in a conventional hydraulic control apparatus can be eliminated, which simplifies the configuration, and reduces the size of a hydraulic control apparatus for a torque converter with a lock-up clutch. When the lock-up clutch is engaged, hydraulic pressure output from the linear solenoid valve is supplied to a disengagement-side oil chamber of the torque converter, and a pressure difference between the engagement-side oil chamber and the disengagement-side oil chamber is applied to a spool valve element of the linear solenoid valve. Therefore, the spool valve element is driven such that an electromagnetic force applied from a linear solenoid becomes equal to the pressure difference.
