<p>During the interval from t1 when the motor torque is reduced toward 0 by the operation of releasing the gas pedal (when the gas pedal stroke amount STacc is reduced to 0), at t2 the target gear range becomes a high gear range, and an upshift gear change request is generated in conjunction with the decrease in torque. However, this gear change request is not executed until t3 when a delay time TMs from t2 has elapsed, and when this gear change request is executed when t3 arrives, the automatic transmission is upshifted from the currently selected low gear range to the high gear range. Accordingly, even if there is a request to increase the motor regenerative torque due to a brake operation immediately (t2-t3) after the moment t2 of the upshift gear change request in response to the torque decrease (the release of the gas pedal), a gear change is not executed in concert with this request, so it is possible to avoid the occurrence of a repetitive gear change from low range -> high range -> low range in a short period of time.</p> |
