摘要： If oil temperature is equal to or higher than a predetermined temperature and if accelerator opening change rate is equal to or higher than a predetermined change rate upon detection of a downshift instruction (YES in S302), an ECT-ECU sets modes corresponding to conditions for determination period calculation processings (S400), hydraulic-pressure temporal change rate calculation processings (S500), and torque adjustment amount calculation processings (S600), respectively. By performing downshift (S310) on the basis of a determination period, a hydraulic-pressure temporal change rate, and a torque adjustment amount corresponding to a set mode, the ECT-ECU improves gear-shift responsive characteristics and restrains the occurrence of a gear-shift shock.
