Abstract

The disclosed automatic transmission controller is capable of changing shift timing set for non-flat roads in correspondence to a judged driver type. The automatic transmission controller executes a driver type judging routine SUB2 to generate a judgment output related to the driver type by monitoring the driving of the vehicle and judges the driver type based on the judgment output. Shift timing is changed in running a non-flat road to correspond to the judged driver type. The shift timing in running the non-flat road may be changed by changing from an uphill slope mode 1 shift map to an uphill slope mode 2 shift map corresponding to the driver type or by increasing an upshift inhibiting section of a single map.
