A shift control apparatus (80) for a vehicle (10; 100) provided with a drive power source (39; MG), and a step-variable transmission portion (20; 110) including a plurality of hydraulically operated coupling devices (CB), the shift control apparatus controlling the step-variable transmission portion to implement a shifting action with an engaging action of the engaging-side coupling device and a releasing action of the releasing-side coupling device, and including a shift control portion (82) to control a shift-down action of the step-variable transmission portion in a predetermined mode of hydraulic control of the engaging-side and releasing-side coupling devices, wherein the shift control portion controls the engaging-side and releasing-side coupling devices in a non-vehicle-driving control mode during the shift-down action of the step-variable transmission portion in a non-driving state of the vehicle, the shift control portion switching the mode of hydraulic control from the non-vehicle-driving control mode to a vehicle-driving control mode where the vehicle is switched from the non-driving state to a driving state within a predetermined length of time after a moment of initiation of the shift-down action, and maintaining the non-vehicle-driving control mode where the vehicle is switched to the driving state after the predetermined length of time has passed, while limiting a torque of the drive power source during the shift-down action to a predetermined value in the non-vehicle-driving control mode.
A shift control apparatus for a vehicle provided with a drive power source, and a step-variable transmission portion disposed in a power transmitting path between the drive power source and drive wheels and including a plurality of hydraulically operated coupling devices, the shift control apparatus controlling the step-variable transmission portion to implement a shifting action with an engaging action of an engaging-side coupling device to be brought into an engaged state to implement the shifting action, and a releasing action of a releasing-side coupling device to be brought into a released state, said shift control apparatus comprising:
