    摘要: When an engagement of the dog clutch is requested, the dog clutch is engaged while allowing satisfactory sound vibration performance regardless of whether the main drive wheels are in a non-slip state or a slip state. The system for transmitting drive force to the left and right rear wheels (19, 20) comprises a dog clutch (8) and an electronically controlled coupling (16), and a 4WD control unit (34) controls the engagement and disengagement of the dog clutch (8) and the engagement and disengagement of the electronically controlled coupling (16). In this clutch control device for a four-wheel drive vehicle, when there is a request to engage the dog clutch (8) from a disengaged state, the 4WD control unit (34), during the engagement control of the electronically controlled coupling (16), first controls the engagement of the electronically controlled coupling (16), monitors the change gradient ”N/dt of the clutch rotational speed difference ”N of the dog clutch (8) and starts engagement of the dog clutch (8) when it is determined that the gradient of the clutch rotational speed difference ”N is no longer decreasing.

    摘要: To achieve a balance between ensuring four-wheel drive performance during re-acceleration and reducing friction in a drive transmission system during braking when the foot is lifted off an accelerator in a low-speed region when the connected, four-wheel drive mode has been selected. The system for transmitting drive force to the left and right rear wheels (19, 20) comprises a dog clutch (8) and an electronically controlled coupling (16); a 4WD control unit (34) is provided, which controls the engagement and disengagement of the dog clutch (8) and the engagement and disengagement of the electronically controlled coupling (16). In this clutch control device for a four-wheel drive hybrid vehicle, the four-wheel drive hybrid vehicle includes a "disconnected, two-wheel drive mode" and a "connected, four-wheel drive mode." When the foot is lifted off an accelerator in a low-speed region when the "connected, four-wheel drive mode" is selected, the 4WD control unit (34) maintains the "connected, four-wheel drive mode" while the brakes are not depressed, and shifts the mode to the "disconnected, two-wheel drive mode" when the brakes are depressed.

    摘要: To achieve a balance between ensuring four-wheel drive performance, on the one hand, and energy conservation performance, on the other, when there is a request to engage the dog clutch. The system for transmitting drive force to the left and right rear wheels (19, 20) comprises a dog clutch (8) and an electronically controlled coupling (16); a 4WD control unit (34) is provided, which carries out the control of starting the engagement of the dog clutch (8), which is in a disengaged state, after placing the dog clutch (8) in a rotationally synchronized state by engaging the electronically controlled coupling (16) and increasing the output rotation thereof, when there is a request to engage the dog clutch (8). In this clutch control device for a four-wheel drive vehicle, the 4WD control unit (34) sets the engagement start timing of the electronically controlled coupling (16) when a transition is made to the "connected, four-wheel drive mode" to an earlier timing compared to when a transition is made to the "standby two-wheel drive mode," when there is a request to engage the dog clutch (8) while in a state in which the "disconnected, two-wheel drive mode" is selected.
