摘要： A failure detecting apparatus for a hydraulic circuit of a gearbox includes an operating-state detector. The operating-state detector is configured to detect an operating state of a subject to be controlled with a control-signal pressure output from a solenoid valve. A current setting device is configured to set an electrical current supplied to a solenoid so as to close an output oil passage when a modulator valve is normal and to open the output oil passage when an open failure occurs in the modulator valve, while the solenoid valve is conductive. A failure determining device is configured to detect a failure of the modulator valve when the operating state of the subject to be detected by the operating-state detector is abnormal after a value of the electrical current to be supplied to the solenoid is set at the current setting device.

摘要： Vehicle-position-recognition apparatuses, methods, and programs acquire current position information indicating a current position of a vehicle and acquire road information indicating at least one road based on a connection relationship between plural links. The apparatuses, methods, and programs determine a link where the vehicle travels based on the current position information and the road information and generate travel-history information indicating a route that the vehicle travels at a point where a link is branched based on the determined link. The apparatuses, methods, and programs acquire an image of an area surrounding the vehicle, recognize a recognition target in the acquired image, and store the generated travel-history information in the memory in association with information indicating the recognition of the recognition target. The apparatuses, methods, and programs generate learning-priority information indicating a priority of each link branched out at the branch point based on the stored travel-history information and the stored recognition information, the generated learning-priority information usable to determine on which of the links branched out at the branch point that the vehicle is traveling.

摘要： A power transmission mechanism for transmitting a driving force from a drive shaft to a driven member of a gear via a one-way clutch is provided. The one-way clutch includes a swinging clutch portion swingably fitted in a clutch portion housing groove formed in a first end portion of the drive shaft. The swinging clutch portion has a cylindrical portion as the axis of rotation and a projecting portion. When the drive shaft rotates, the projecting portion of the swinging clutch portion is raised by a slit of a collar fitted onto the drive shaft, engaging one of a plurality of engaging grooves formed in the inner peripheral surface of the driven member. When the drive shaft does not rotate, the swinging clutch portion lies down, and the projecting portion does not engage any engaging groove, allowing the driven member to rotate bidirectionally relative to the drive shaft.

摘要： A control system for a variable displacement pump driven by a drive source for driving a vehicle is provided. The variable displacement pump pressurizes hydraulic oil, and is switchable between a full capacity operation in which a discharge flow rate is maximized and a partial capacity operation in which the discharge flow rate is lower than that in the full capacity operation. It is determined whether an operation for starting the drive source has been performed. A rotational speed of the drive source and a temperature of the hydraulic oil are detected. When the rotational speed of the drive source is equal to or higher than a predetermined rotational speed and the hydraulic oil temperature is equal to or lower than a predetermined temperature, immediately after the operation for starting the drive source is performed, the partial capacity operation of the variable displacement pump is performed. This control suppresses generation of untoward noises caused by the operation of the variable displacement pump when starting to drive the vehicle.
