Patent ID: 7150698

Claim:
A control unit for a power transmission apparatus for use in an automobile comprising: (a) an engine; (b) a gear-type transmission having: (b1) a first input shaft to which power is transmitted from said engine through a first friction clutch; (b2) a second input shaft to which motive power is transmitted from said engine through a second friction clutch; (b3) a plurality of gear trains provided between said first input shaft and an output shaft and between said second input shaft and said output shaft; and (b4) a claw clutch provided on said gear trains; (c) a first motor connected to said first input shaft; and (d) a second motor connected to said second input shaft, wherein, said control unit is configured to control said first or second motor so as to suppress a thrust or push-up on torque of said output shaft due to inertia torque after torque transmitted by said second friction clutch coincides substantially with output shaft torque of said engine in conducting a gear-shift through a change-over from said first friction clutch to said second friction clutch.
