ABSTRACT:
A vehicle shift control apparatus is basically provided with an engine, a drive wheel, a transmission and a controller. The transmission is operatively disposed between the engine and the drive wheel for shifting gears by executing a clutch switch operation so as to change a drive transmission path of the transmission. The controller is operatively to the transmission to control a gear shifting of the transmission. The controller includes an engine speed suppressing section that is configured to execute an engine speed suppression control when a driver performs an accelerator operation during the clutch switch operation associated with downshifting while coasting. The engine speed suppression control is further configured to reduce a torque capacity decrease rate of a clutch being released in comparison with a torque capacity decrease rate that would occur if shifting was taking place during normal coasting in which the accelerator operation is not performed.
