摘要： When an oil temperature Toil is equal to or lower than a threshold Toref, and when a vehicle is predicted to stop while traveling (a shift position is predicted to be operated to a parking position), restricted discharge processing is executed in which a magnetic lock device is turned ON and an on-off solenoid valve is turned OFF. Thus, discharge of hydraulic oil in an oil chamber is started while movement of a piston rod is restricted by the magnetic lock device. Then, when the vehicle stops and the shift position is changed to a parking position, the restriction on the movement of the piston rod is removed by turning OFF the magnetic lock device.

摘要： A method for operating an automatic transmission apparatus having a parking lock device. The parking lock device has a hydraulic apparatus with a hydraulic cylinder and a hydraulic piston arranged therein, which can be placed in at least two positions by a lock apparatus and an emergency unlock apparatus. The hydraulic piston is operatively connected to a shifting shaft of the parking lock device, and a pressure can be adjusted in the hydraulic cylinder by a hydraulic valve. The shifting shaft can be shifted within an operating position range by the hydraulic apparatus. In doing so, upon activation of the emergency unlock apparatus, the shifting shaft is shifted into a position that is outside of the operating position range, and an operating state of the emergency unlock apparatus is checked.

摘要： A magnetic lock device includes a lock shaft having an abutting portion capable of abutting against a roller of a piston rod of a hydraulic pressure actuator, a transfer shaft configured separately from the lock shaft, the transfer shaft abutting against an end surface of the lock shaft, and a magnetic portion locking (restricting movement to the right side in the drawing) the lock shaft, the transfer shaft, and a plunger by attracting the plunger toward an attracting portion using a magnetic force. The lock shaft is surface-hardened to have a higher hardness and the transfer shaft is made of non-magnetic material.

摘要： A park-by-wire system uses a single spring to bias the system towards park and to permit a ratcheting feature which delays the engagement of park until vehicle speed drops below a threshold. A cam slides with respect to a rod. A stop on the rod limits travel in one direction. The spring biases the cam toward the stop but compresses as necessary to allow the cam to move during ratcheting operation. The spring reacts against the housing. Acting through the cam and the stop, the spring biases the rod toward the park position. The design limits the number of components that move during ratcheting operation. Specifically, the rod and actuator do not oscillate during ratcheting operation.

摘要： A hydraulic unit and an electromagnetic unit are disposed such that a piston rod of the hydraulic unit and a solenoid shaft of the electromagnetic unit are orthogonal to each other. The electromagnetic unit is configured such that an end surface of an expanded diameter portion of a shaft portion of the solenoid shaft on the piston rod side is pressed against an attracting portion of a yoke by the elastic force of a spring when a parking unlocked state is established by a hydraulic pressure.

摘要： In case of power supply loss, a parking lock is operated by moving a piston of a hydraulic actuator rightward by use of hydraulic pressure accumulated in an accumulator. If a hydraulic pressure generating source becomes unable to generate line pressure due to its failure after the power supply loss, it is desirable that the parking lock be releasable to tow a vehicle, for example. In that time, because the hydraulic pressure in the accumulator has got out via an orifice, the parking lock can be released by moving the piston in the hydraulic actuator leftward by use of a manual operation device without interruption by the hydraulic pressure accumulated in the accumulator. Because the hydraulic pressure in the accumulator is automatically released via the orifice, a complicated mechanism for enabling the manual operation device to work without interference from the hydraulic actuator becomes unnecessary.

摘要： In a hydraulic control arrangement for an automated shift transmission, in particular a dual clutch transmission in a motor vehicle including a hydraulic control arrangement, the hydraulic control arrangement has a main pump and a controllable additional pump which jointly ensure that oil is supplied to the hydraulic control arrangement. The additional pump can feed into a control channel of a lubricating pressure slide and build up an adjustable lubricating fluid control pressure. The lubricating fluid pressure in the lubricating cooling system is adjusted in a simple and inexpensive manner by lubricating pressure slide changes modifying the lubricating control pressure in the lubricating cooling system.
