  • Patent number: 10487931
    Abstract: The invention concerns a method for actuating a differential lock of a differential in a motor vehicle drive-train, such that when a locking command has been issued the differential lock is engaged as soon as there is essentially no rotational speed difference at the differential lock (S8). To carry out a comfort-orientated actuation of the differential lock, when the locking command has been issued but before the differential lock is engaged, it is first checked whether there is a rotational speed difference at the differential lock (S6). If there is a rotational speed difference, this is automatically reduced before the differential lock is engaged (S7).

  • Patent number: 9994225
    Abstract: A powertrain system includes a geartrain configured to transfer mechanical power between an internal combustion engine, torque machines and a driveline by activation of a synchronous engagement clutch. A method includes commanding activation of the synchronous engagement clutch, including commanding operations of the engine and the first and second torque machines to control members of the clutch, including monitoring speeds thereof. A magnitude of clutch slip is determined. A zero-slip feedback control routine is executed when the clutch slip approaches a zero-slip state, wherein the zero-slip feedback control routine is operative to control the engine and the first and second torque machines to control the rotational speeds of the opposed first and second members to achieve zero clutch slip. The synchronous engagement clutch is activated when the clutch slip is less than a threshold level associated with the zero-slip state.

  • Patent number: 9981552
    Abstract: A clutch control device is provided for a four-wheel drive vehicle for transmitting drive force to the rear wheels. The clutch control device includes a dog clutch and a friction clutch, and a 4WD control unit that controls the engagement and disengagement of the dog clutch and the friction clutch. The 4WD control unit is switchable between a two-wheel drive mode and a four-wheel drive mode. The 4WD control unit is programmed to control engagement of the dog clutch so that the dog clutch is engaged after the friction clutch is engaged and the dog clutch is synchronized. During engagement of the dog clutch, the 4WD control unit is programmed to reduce a transmission torque of the friction clutch when the dog clutch engagement standby state is detected.

  • Patent number: 9925869
    Abstract: A transfer case for a four-wheel drive motor vehicle includes a two-speed range clutch unit, a mode clutch unit, a power-operated actuation mechanism and a control system. The actuation mechanism includes an electric motor, a geartrain driven by the motor for controlling rotation of an actuator shaft, a range actuator assembly and a mode actuator assembly. The range actuator assembly functions to move a shift collar associated with the range unit in response to rotation of the actuator shaft. The mode actuator assembly includes a mode cam and a ballramp unit. The mode cam is rotatively driven by the actuator shaft for controlling the clutch engagement force exerted on the friction clutch by the ballramp unit. The control system controls movement of the shift collar during motive operation of the motor vehicle to permit on-the-move range shifting.
