    摘要: A control device of an automatic transmission to set and control a gear position based on a vehicle speed and an accelerator opening degree, includes a controller determining a high load travel based on a travel resistance during travel control on a gear shift line, which is set such that a region on a higher accelerator opening degree side of a downshift line is a region where a lock-up clutch is to be turned off, and turning off the lock-up clutch before downshifting when determining the high load travel.

    摘要: A cooling system for a vehicle that includes a temperature detection device for detecting a temperature related to a power transmission apparatus. The cooling system includes a cooling fan and an electronic control apparatus including a load limiting portion configured, when the detected exceeds a limit temperature value, to limit a load applied to the power transmission apparatus. The electronic control apparatus is configured to determine whether the detected temperature is equal to or higher than a fan-cooling temperature value that is lower than the limit temperature value, and to control rotation of the cooling fan, such that the cooling fan is rotated when the detected temperature is not lower than the fan-cooling temperature value, and such that a rotational speed of the cooling fan is higher when a temperature of the power transmission apparatus is high, than when the temperature of the power transmission apparatus is low.

    摘要: A vehicle controller controls a vehicle including an engine and an automatic transmission. The vehicle controller includes an electronic control unit. The electronic control unit estimates power generable by the engine based on a condition of the engine and a condition of the automatic transmission in a non-driving range, calculates a load on the automatic transmission in a driving range based on a condition of the automatic transmission in the driving range, determines whether a difference between the power and the load is equal to or smaller than a predetermined threshold by which an engine stall is identifiable, and limits a gear shift request from the non-driving range to the driving range when the difference is equal to or smaller than the predetermined threshold.
