192220000 | Brake control affects transmission change | 16 |
20080302628 | SHIFT RANGE CONTROL APPARATUS - A rod-lock mechanism is provided in an automatic transmission for a vehicle. The rod-lock mechanism has an engaging pin which will be engaged with a rod when the rod is in its initial position, so as to hold the rod in its initial position. The rod-lock mechanism further has an electric actuator for driving the engaging pin when electric power is supplied, so that the engaging pin is brought out of engagement from the rod. A forced parking current supply unit controls electric power supply to the electric actuator. When the electric power is supplied to the electric actuator, the rod is moved in a direction of a parking position to bring a vehicle into a parking condition. | 12-11-2008 |

20130292223 | Pre-Staging and Boosting for Downshifts to Increase Regenerative Braking - A hybrid vehicle has a battery, a regenerative braking system, a transmission, and a controller. The controller boosts and strokes a hydraulic cylinder of an on-coming clutch when the state-of-charge of the battery allows regenerative braking and in response to a pedal actuation. The controller boosts and strokes the hydraulic cylinder before a disconnect clutch is opened and the transmission is downshifted to increase regenerative braking efficiency. | 11-07-2013 |

20100326787 | OPERATING DEVICE FOR A VEHICLE HAVING AN AUTOMATIC TRANSMISSION AND AN ELECTRICALLY ACTUATED PARKING BRAKE SYSTEM - The invention relates to an operating device for a vehicle having an automatic transmission and an electrically actuated parking brake system, comprising at least one mechanical actuation element for inputting operating commands of the vehicle user and a control unit for converting the operating commands into control signals to the transmission and the parking brake system, wherein according to the invention the actuation element ( | 12-30-2010 |
20120211326 | Hydraulic Control Device for Hybrid Transmission - A hydraulic control device for a hybrid transmission is designed such that the cooling and lubrication oil line of the system are in oil communication even before the main oil line pressure reaches the set pressure of the overflow valve, so as to lubricate the transmission as soon as possible. The hybrid transmission design further provides an overpressure protection for the cooler. The hybrid transmission further uses a proportional pressure reducing valve to control the lock-up clutch, thus making for the improvement of its braking performance. | 08-23-2012 |

20130020171 | PARKING BRAKE SYSTEM - A parking brake system that uses a locking device to maintain a parking release condition may include a control lever that may be rotatably connected to the exterior of a transmission, a shift cable that may be rotatably connected to an end of the control lever, the locking device that may be connected to the other end of the shift cable and selectively maintains the parking release condition, and a parking device that includes a piston member in a cylinder and that may be connected to the end of the control lever and uses hydraulic pressure to move the control lever and the shift cable such that the parking release condition may be maintained. | 01-24-2013 |
20130161149 | PARKING LOCK DEVICE - Upon shifting a parking lock device from an unlocked state to a locked state, the power supply to a motor is interrupted when a fitting member reaches a first position of an outer peripheral surface of a position determining plate. At that moment, the rotational energy of a rotation body is absorbed by a rotational energy absorption member. Also, upon shifting the parking lock device from the locked state to the unlocked state, the power supply to the motor is interrupted when the fitting member reaches a second position. At that moment, the rotational energy of the rotation body is absorbed by the rotational energy absorption member as well. | 06-27-2013 |
20130313066 | VEHICLE PARKING LOCK DEVICE - A vehicle parking lock device stopping rotation of a parking gear formed on a rotating member coupled to drive wheels to stop rotation thereof, including: a parking pole having a claw portion for engagement with the parking gear, the parking pole being rotatable around a support shaft by pushing out a cam movable in an axial direction of the parking gear, the support shaft being in parallel with the axial direction; a stopper plate contacting the parking pole to regulate movement in the axial direction; and a spring contacting the parking pole to bias it in a direction of release of engagement between the claw portion and parking gear, the vehicle parking lock device being configured to dispose a contact point of the contact between the spring and parking pole closer to the stopper plate in the axial direction than a contact point between the parking pole and cam. | 11-28-2013 |
20140041986 | ACTUATOR ARRANGEMENT FOR A DRIVE TRAIN - Actuator arrangement for a drive train. The actuator arrangement has an actuator pump driven by electric motor, and a clutch actuator, which is designed for actuation of a friction clutch of the drive train and which is connected to a discharge port of the actuator pump. The actuator arrangement has a parking lock actuator, which is designed for actuation of a parking lock arrangement of the drive train. The parking lock actuator has an open position, in which the parking lock arrangement is released, and a closed position, in which the parking lock arrangement is closed. The parking lock actuator is likewise connected to the discharge port of the actuator pump. The parking lock arrangement can be retained in at least one of the open position and the closed position by means of a retaining device. | 02-13-2014 |
