Abstract: A hydraulic circuit device for a vehicle, includes a clutch, a flow path, a fluid pump, a pressure generating device, and a control valve. The control valve is configured to determine whether a transmission start-stop function activation condition other than a vehicle speed is satisfied, determine whether a system start-stop function activation condition related to a component of the vehicle is satisfied, the component being other than the transmission, determine whether the vehicle speed is equal to or lower than a first speed threshold, and boost a line pressure of the flow path to accumulate pressure in the pressure generating device for preparing activation of the start-stop function if it is determined that the transmission start-stop function activation condition and the system start-stop function activation condition are satisfied, and if it is determined that the vehicle speed is equal to or lower than the first speed threshold.

Abstract: A control apparatus of an automatic transmission connected to an internal combustion engine of a vehicle includes a determination unit configured to determine an operation state of a hydraulic oil temperature sensor based on comparison between a threshold and a difference between a hydraulic oil temperature of the automatic transmission and a cooling water temperature of the internal combustion engine. When the operation state of the hydraulic oil temperature sensor is determined as normal by the comparison with the threshold, the determination unit further determines the operation state of the hydraulic oil temperature sensor based on an operation state of an oil pressure sensor determined using the hydraulic oil temperature, an oil pressure of hydraulic oil, and a rotation speed.

Abstract: An automatic transmission capable of properly judging faults of a switching mechanism is provided. A control part ECU of the automatic transmission TM has an actual change gear ratio calculating part 10 and a fault judging part 11. Under a condition that the control part ECU has recognized that the first brake device B1 is switched to a reverse rotation preventing state, if the actual change gear ratio is kept to be an actual change gear ratio prior to a reduction of a rotational speed of a drive source ENG when the rotational speed of the drive source ENG is reduced, then the fault judging part 11 judges that a first brake B1 has a fault.

Abstract: In a vehicular parking lock device, supplying a hydraulic pressure from pressure regulation of a line pressure by a linear solenoid valve to a hydraulic brake via a switching valve operated by a first solenoid valve enables a transmission to carry out a shift change. If desired that a parking lock is not operated when an engine stops, the hydraulic pressure stored under pressure in an accumulator is discharged to a drain oil passage by connecting the linear solenoid valve selectively to the drain oil passage by the first solenoid valve, thereby making it possible to prevent the hydraulic pressure stored under pressure in the accumulator from being supplied to a locking oil chamber at the other end of the hydraulic actuator. The first solenoid valve is used for both controlling the operation of the hydraulic brake and discharge of the hydraulic pressure stored under pressure in the accumulator.

Abstract: An automatic transmission of this invention includes a plurality of engaging mechanisms, and the plurality of engaging mechanisms include a mechanical engaging mechanism that functions as a brake. The mechanical engaging mechanism can switch a rotational element between a first state in which rotation is restricted only in one direction and a second state in which rotation is restricted in both directions. When switching from the first state to the second state, engagement control is started in advance for at least one of the plurality of engaging mechanisms to be set in an engaging state.

Abstract: There is provided an automatic transmission capable to preventing an output of a driving source in a neutral range from being transmitted to wheels without increasing the number of control valves which could fail. An automatic transmission includes a first brake, a third clutch, a third brake, a transmission control device configured to control the first brake, the third clutch, and the third brake, and a hydraulic sensor and a hydraulic switch configured to determine whether the first brake is under control of the transmission control device. When the hydraulic sensor and the hydraulic switch detect that the first brake is in an engaged state contrary to control of the transmission control device in a non-traveling range, the transmission control device switches the third clutch and the third brake to the engaged state.

Abstract: A control apparatus of an automatic transmission, which includes a mechanical engaging mechanism functioning as a brake, includes a determination unit determining, when a selected gear is a lowest forward speed gear, and the mechanism is in a second state, whether to switch the mechanism to the first state, and a switching processing unit switching the mechanism to the first state based on a determination result. In the first state, only rotation of a predetermined rotational element provided in planetary gear mechanisms in a first direction is restricted. In the second state, rotation of the predetermined rotational element in both the first and second direction is restricted. The determination unit determines to switch the mechanism to the first state at least on condition that a driving force is larger than a predetermined driving force.

Abstract: Provided is an automatic transmission with which a large impact is hardly applied to the component of the switching mechanism or the switching control circuit when the drive source is re-driven. When a drive source ENG is determined to be in the stopped state, if the position of a slider HC1 does not correspond to the position the control partECU instructed before the drive source ENG is determined to be in the stopped state, the control part ECU of the automatic transmission TM transmits a signal for switching a two-way clutch TW to a state corresponding to the state of a slider HC1.

Abstract: A control apparatus for controlling an automatic transmission including a torque converter to which a driving force of an engine is input includes a specifying unit configured to specify a drag torque of a wet friction type lock-up clutch, and a transmission unit configured to transmit load information including at least the drag torque specified by the specifying unit to a control apparatus of the engine. The specifying unit specifies the drag torque of the lock-up clutch during in-gear based on a slip ratio of the torque converter before in-gear when the lock-up clutch is released.
