  • Patent number: 11473650
    Abstract: A method of operating a shifting system for a vehicle transmission includes engaging a clutch to operatively couple one of first and second gear ratios to an input member, and moving a disconnect from a first disconnect position where a disconnectable component is disengaged from the disconnect, to a second disconnect position where the disconnectable component is engaged with the disconnect to operatively couple the other of the first and second gear ratios to the input member through a shifting assembly. Engaging the clutch and moving the disconnect are performed such that the clutch is operatively coupled to one of the first and second gear ratios at the same time that the shifting assembly is operatively coupled to the other one of the first and second gear ratios, thus preventing torque from being transmitted through either the first and second gear ratios of the vehicle transmission to park the vehicle.

  • Patent number: 11453378
    Abstract: A method for controlling a drive train of a hybrid vehicle which includes an internal combustion engine, an electric machine that is operated as a motor or generator, and a transmission. Energy is recovered in the overrun operation of the vehicle by operating the electric machine in generator mode. The transmission has at least one free-wheel-connected low forward gear that only transmits traction torque, and at least one free-wheel-free high forward gear. When the free-wheel-connected low forward gear is engaged and the vehicle transitions into the overrun operation, or the driver requests a transition into the overrun operation by selecting the free-wheel-connected low forward gear, an overrun torque is set via the free-wheel-free high forward gear by a generator operation of the electric machine for energy recovery. The overrun torque thereby substantially corresponds to an overrun torque of a free-wheel-free configuration of the free-wheel-connected low forward gear.

  • Patent number: 11079010
    Abstract: An angle calculation unit acquires a motor rotation angle signal, output from a motor rotation angle sensor detecting a rotational position of a motor, and calculates a motor angle. A signal acquisition unit acquires an output shaft signal that is output from an output shaft sensor and has a value changing stepwise in accordance with a rotational position of an output shaft, the output shaft sensor detecting a rotational position of an output shaft to which the rotation of the motor 10 is transmitted. A drive control unit controls the drive of the motor such that the motor angle becomes a target motor angle value corresponding to a target shift range. A range determination unit determines an actual range based on the output shaft signal and the motor rotation angle signal.

  • Patent number: 11041535
    Abstract: A control apparatus for a synchronous meshing mechanism that is equipped with a gear, a sleeve, a synchronizer ring, and a hydraulic actuator is provided. When it is determined that the sleeve and the gear have been rotationally synchronized with each other in an engagement transition period of the synchronous meshing mechanism, an electronic control unit with which the control apparatus is equipped sets a command pressure for the hydraulic actuator to an intermediate pressure that is lower than a meshing completion pressure. Besides, when meshing has not been completed even after the lapse of a predetermined time from a timing when the command pressure for the hydraulic actuator is set to the intermediate pressure, the electronic control unit sets the command pressure for the hydraulic actuator to the meshing completion pressure.

  • Patent number: 11035420
    Abstract: The transmission includes a rotation shaft, a shift gear, and a gear switching part. The shift gear is rotatably supported by the rotation shaft. The gear switching part is relatively unrotatably supported by the rotation shaft in a movable manner in an axial direction. The gear switching part is configured to be moved in the axial direction by a shift fork, to switch connection and disconnection between the rotation shaft and the shift gear. The gear switching part and the shift fork have a bearing therebetween. The bearing is brought into contact with the gear switching part and the shift fork, thereby reducing friction between the gear switching part and the shift fork, resulting in improvement of durability of the sliding surfaces of the gear switching part and the shift fork.

  • Patent number: 10955048
    Abstract: A method of controlling an automated manual transmission system having a transmission and a shifter is provided. The shifter includes a Drive Mode, a Low Mode and at least one of a Manual Mode and a Hold Mold. The Drive Mode automatically selects a default gear of the transmission and automatically performs all upshifts and downshifts. The Manual Mode permits an operator to manually select an upshift and a downshift of the transmission. The Hold Mode permits an operator to maintain a current operating gear. Control determines whether the shifter is in one of the Manual Mode and the Hold Mode. Control determines whether a vehicle operating condition is outside of a predetermined threshold. Control operates the transmission in Drive Mode based on the vehicle operating condition being outside of the predetermined threshold irrespective of the shifter being in one of the Low Mode, Manual Mode or Hold Modes.
