    摘要: The clutch control apparatus includes a first reference value setting portion for setting a first engagement amount reference value of the first and the second clutches and to obtain a target transmitting torque by calculating a target inertia torque by multiplying a target rotation speed change rate of the engine at a speed change operation by an inertia of the engine and subtracting the target inertia torque from the current output torque of the engine to be the target transmitting torque of the first and the second clutches and a second reference value setting portion for setting a second engagement amount reference value by correcting the first engagement amount reference value based on the vehicle speed and the turning radius.

    摘要: A method for controlling operation of a transfer case in a motor vehicle driveline that includes by an engine controlled by a throttle having a variable position, and a transmission driveably connected to the engine for producing multiple ratios of the speed of a transmission input relative to the speed of a transmission output. The transfer case transmitting rotating power in response to an electric signal applied to a clutch. The method includes determining that the engine throttle position is less than a first reference throttle position during a period of predetermined length; determining that a speed of the vehicle speed is in a predetermined range; determining that the transmission is operating in a speed ratio greater than a reference speed ratio; determining that the engine throttle position is greater than a first reference throttle position; and increasing the torque capacity of the clutch for a predetermined period.

    摘要: The object of the present invention is to suppress the generation of abnormal noise from a transmission system that occurs when a vehicle is turning. A front wheel output shaft is directly linked with the transmission system, and a rear wheel output shaft is linked to the transmission system via a transfer clutch. When the front wheel output shaft rpm Nf and the rear wheel output shaft rpm Nr separate from each other beyond a specified value (α2) while turning a corner, and then the accelerator pedal is released and the engine rpm Ne and turbine rpm Nt approach each other beyond a specified value (β2), and then if vibration at a specified vibration frequency appears in the front wheel output shaft rpm Nf (γ2), the duty ratio Rd of the clutch pressure control valve 52 is decreased (δ2). Next, as the duty ratio Rd decreases, when it is determined that vibration in the front wheel output shaft rpm Nf has been eliminated (ε2), normal slip control is restored, and control is performed so that the duty ratio Rd is increased again (ζ2). By doing this, it is possible to suppress vibration of the front wheel output shaft, and thus suppress the generation of abnormal noise from the transmission system.
