As a result of increasingly opening a throttle (APO) starting at time t1, as shown in the figure, kick-down starts at time t2, and while said kick-down is being executed by means of a shift from a releasing element (a direct clutch (D/C)) to an engaging element (a high-and-low reverse clutch (H&LR/C)), the motor torque (tTm), which increases as indicated by Tmo as the throttle (APO) opens, is constrained as follows: during the initial phase of the shift, from time t2 to the beginning of the inertia phase at time t3, the motor torque (tTm) is constrained to at most a maximum (Tlimit = Tmo2 - Tip) obtained by subtracting a torque-increase amount (Tip) for proceeding to the inertia phase from the maximum motor torque (Tmo2) that can be outputted at the motor speed (Nmo2) at the end of the inertia phase at time t4; and during the inertia phase, from time t3 to t4, the motor torque (tTm) is constrained to at most Tlimit + Tip (i.e., to at most Tmo2). |
