  • Patent number: 10865839
    Abstract: A clutch control device and a clutch control method are capable of preventing progress of wear and damage of a pneumatic clutch actuator. The clutch control device that controls the operation of a pneumatic clutch actuator to disconnect a clutch is characterized by setting a stroke amount of a piston corresponding to a disconnection position of the clutch as a final target stroke amount, setting other stroke amounts different from the final target stroke amount as intermediate target stroke amounts, and controlling the operation of the piston in a stepwise manner such that an actual stroke amount of the piston is matched with the intermediate target stroke amounts and is thereafter matched with the final target stroke amount, thereby disconnecting the clutch.

  • Patent number: 10851889
    Abstract: While automatic driving control is being performed, traveling in a driving state of a vehicle corresponding to an unconverged region (including an unperformed region and a performed region) is preferentially selected between the traveling in the driving state of the vehicle corresponding to the unconverged region, and traveling in the driving state of the vehicle corresponding to a converged region. As such, learning control that corrects an amount of operation associated with control of the vehicle is performed more easily throughout the entire learning regions regardless of a usage state of the vehicle by a driver. Therefore, it is possible to achieve an appropriate traveling state at an early stage by the learning control that corrects the amount of operation associated with control of the vehicle.

  • Patent number: 10844954
    Abstract: A shift range control device switches a shift range by controlling a drive of a motor, and includes an abnormality monitoring unit and a torque control command unit. The abnormality monitoring unit detects an abnormality occurrence of an intermediate range stop in which the output shaft to which the drive of the motor is transmitted stops in an intermediate range region. The intermediate range region is a range outside a range guarantee region that guarantees the function of each range. When an abnormality of the intermediate range stop occurs, the torque control command unit commands suppression of the torque applied to the automatic transmission.

  • Patent number: 10837525
    Abstract: A motor vehicle transmission for coupling an electric machine to a drivetrain of an electrically driveable motor vehicle. The motor vehicle transmission includes a planetary transmission for converting a torque that is introducible by the electric machine. An internal gear of the planetary transmission has an input toothed gear for forming a spur gear stage with a drive shaft of the electric machine. A brake immobilizes a sun gear of the planetary transmission with a static housing. A clutch rotationally conjointly connects the sun gear to the internal gear. The brake and the clutch at least partially overlap as viewed in a radial or axial direction. By virtue of the overlap, it is possible for axial and radial structural space, respectively, to be saved, such that a motor vehicle transmission with a small structural space requirement is made possible.

  • Patent number: 10821957
    Abstract: A transmission includes a selectable one-way clutch with active and passive states. Successful transition from the active state to the passive state is only possible when there is no torque tending to cause overrunning. After commanding a transition from the active state to the passive state, a controller partially engages a first friction clutch to induce a torque tending away from overrunning until a lash crossing is detected. Then, the controller releases the first clutch and partially applies a second clutch to induce a torque toward overrunning. When slip is detected, indicating successful achievement of the passive state, the second clutch is released.

  • Patent number: 10814858
    Abstract: Methods and controllers for coordinating firing fraction transitions that occur in conjunction with transmission shifts are described. In some embodiments, when a transmission shift to a target gear is expected, a target firing fraction is determined that is desired for use after the shift has completed. In selected circumstances, the change to the target firing fraction is initiated prior to the shift to the target gear. The transition to the target firing fraction preferably completes before an inertia/speed phase of the shift. In other embodiments, the engine transitions to all cylinder operation or other suitable transitional firing fraction in response to an expected transmission shift. After the shift completes, a transition is made to a target firing fraction. The described approaches are well suited for use during skip fire or other cylinder output level modulation operation of the engine and are particularly beneficial during up-shifts.
