Abstract:
A shift control system for vehicle that improves an acceleration feeling while suppressing a shift shock includes a controller that controls a transmission and a hydraulic controller. The controller, during an inertia phase where an input speed of the transmission changes toward a synchronous speed in a gear stage after a shift, sets an oil pressure of a specific frictional engagement device configuring the gear stage after the shift, of a plurality of frictional engagement devices to an oil pressure that, at a time of the shift, exceeds a first oil pressure to set a transmission torque capacity equal to a first drive torque applied to the specific frictional engagement device of a drive torque outputted from a prime mover, but is less than a second oil pressure to set a transmission torque capacity equal to a second drive torque which is the first drive torque to which has been added an inertia torque generated by inertia on a prime mover side accompanying a change in speed ratio.

Claim (Index 1):
A shift control system for vehicle, comprising:\n a plurality of engagement devices set to torque capacities based on oil pressures supplied; a geared transmission coupled to an output shaft of a prime mover and including the plurality of engagement devices; a hydraulic controller that controls oil pressures with respect to the plurality of engagement devices in order to shift a gear stage of the transmission to another gear stage having a different speed ratio; and a controller that controls the transmission, wherein the controller is configured so that, during a shift of the transmission, in an inertia phase where an input speed of the transmission changes toward a synchronous speed in a gear stage after the shift, the controller controls an oil pressure of a predetermined engagement device to be engaged to establish the gear stage after the shift, and in the inertia phase, the oil pressure of the predetermined engagement device is set to an oil pressure which is higher than a first oil pressure to set a torque capacity for transmitting from the prime mover a first drive torque acting on the certain engagement device, but lower than a second oil pressure to set a torque capacity for transmitting a second drive torque which is a total of an inertia torque caused by a change in speed of the prime mover and the first drive torque.
