Patent number: 9440533Abstract: A control apparatus for a vehicular 4-wheel drive system provided with: primary drive wheels to which a drive force is transmitted from a drive power source; auxiliary drive wheels to which the drive force is selectively transmitted; a first clutch configured to selectively place a first power transmitting path in a power transmitting state and a power cutoff state; and a second clutch disposed in a second power transmitting path to selectively place the second power transmitting path in a power transmitting state and a power cutoff state. The first and second clutches are placed in fully released states to establish a 2-wheel drive mode. The control apparatus includes a first-clutch control portion configured to bring the first clutch into a partially engaged state when a predetermined condition in which the vehicular 4-wheel drive system generates or is considered to generate a noise is satisfied in the 2-wheel drive mode.Type: GrantFiled: October 14, 2015Date of Patent: September 13, 2016Assignee: Toyota Jidosha Kabushiki KaishaInventors: Yoshinori Maeda, Takahiro Yoshimura, Ryota Horie, Hiroshi Tamura, Hideki Tamoto
