Abstract:
A control device for a vehicle having a gear type transmission comprising a plurality of gears and a plurality of mesh type clutches, for transmitting torque from an input shaft to an output shaft; a first torque transmitting path from said input shaft to said output shaft being formed by engaging said gear with said mesh type clutch, and a second torque transmitting path being formed by controlling a torque correcting apparatus when the engagement of said gear with said mesh type clutch is switched from a first engagement to a second engagement; wherein:when switching said second torque transmitting path to a torque transmitting path formed by said second engagement after disengaging said first engagement, torque fluctuation of said output shaft generated during switching said torque transmitting path by controlling said torque correcting apparatus is reduced by controlling torque of said input shaft before and after switching said torque transmitting path.
