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, an ECT-ECU sets modes corresponding to conditions for determination period calculation processings, hydraulic-pressure temporal change rate calculation processings, and torque adjustment amount calculation processings, respectively. By performing downshift 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.

摘要： An ECT-ECU includes a circuit that calculates an oil temperature threshold on the basis of a signal input from one of an engine coolant temperature sensor, an engine intake air temperature sensor, and an AT hydraulic fluid temperature sensor if a signal for starting an engine of a vehicle is input thereto from an ignition switch, a circuit that detects an oil temperature on the basis of a signal input from the AT hydraulic fluid temperature sensor at intervals of a predetermined sampling time while the vehicle is running, and a circuit that controls an automatic transmission to prohibit a gear shift from fourth speed to fifth speed if a detected oil temperature is lower than the oil temperature threshold.
