  • Patent number: 10793158
    Abstract: The disclosure relates to a method for operating a motor vehicle that includes a drive unit, an output unit, and a clutch arranged between the drive unit and the output unit and configured to transmit a torque. A detection unit detects an operating state of the drive unit. When the operating state of the drive unit is in an overrun mode, a control unit controls a clutch slip, which results in adjustment of the torque that can be transmitted as a function of a speed of the motor vehicle. The disclosure further relates to a device for operating a motor vehicle, and to a motor vehicle that includes such a device.

  • Patent number: 10794435
    Abstract: A transmission includes a selectable one-way clutch with an active state and a passive state. To avoid occupant discomfort and hardware damage, transitions from the passive state to the active state must only be commanded when no or very little slip is present across the selectable one-way clutch. Several methods are presented to eliminate slip, depending on vehicle speed. When the vehicle is stationary, full engagement of a clutch that causes slip to be proportional to vehicle speed eliminates slip. When the vehicle is moving backwards, partial engagement of the above clutch eliminates slip. When the vehicle is moving forwards, full engagement of all but one clutch of a tie-up condition and partial engagement of the remaining clutch of the tie-up condition brings the vehicle to a stop and eliminates slip.

  • Patent number: 10787072
    Abstract: A vehicular control system for reducing shocks by inhibiting switching operation of a dog clutch when drive force cannot be assisted by an engine. A controller determines that an increase in the drive force by the engine is restricted. In a case that an increase in the drive force is not restricted when launching the vehicle, the controller establishes a first gear stage in the transmission to launch the vehicle, and shift to the second gear stage upon satisfaction of a predetermined condition during propulsion while increasing the drive force. In a case that an increase in the drive force is restricted when launching the vehicle, the controller establishes a second gear stage in the transmission to launch the vehicle.

  • Patent number: 10753466
    Abstract: In a transmission control device for controlling a transmission, a controller determines failure of a specific section. The controller variably controls line command pressure and secondary command pressure, and in a case where the failure is determined, fixes the line command pressure to a line pressure set value and the secondary command pressure to a secondary pressure set value. In a case where the failure is determined, the controller further starts a change in the secondary command pressure after start of a change in the line command pressure, and controls the secondary command pressure in such a manner that the secondary command pressure takes a first predetermined time to have the secondary pressure set value.

  • Patent number: 10731737
    Abstract: An angle-measuring device is provided for a rotationally-driven linear actuator, which can be implemented into a clutch actuator. A rotor element has an axis of rotation and rotates concentrically with a rotor of a rotary drive for an axially movable linear actuator element. A measurement magnet arrangement is fixed relative to the rotor element and has a polarization. The polarization is oriented in such a way that the magnetic field lines can change with a rotation of the rotor element so as to enable the angle to be precisely determined from at least one measurement position. At one location, a 360-degree sensor is provided for measuring angular positions based on the measurement magnet arrangement. At another location, a revolution-counting sensor is provided for counting a number of revolutions carried out based on the measurement magnet arrangement.
