(57) [Summary] [PROBLEMS] To select one of a plurality of maps set in advance by obtaining a slope parameter or a slope parameter of a vehicle to control a shift, and to input navigation information to shift more appropriately. The ratio is determined, and the navigation information is not affected even when it is incorrect. SOLUTION: When it is determined from the navigation information that the vehicle is in the uphill / downhill correction section (S408), the downhill gradient parameter PKUAVE (PKUAVE2) is added and corrected by the (excess) load weight estimation value HWATNAVI (S41). 2). Therefore, the map in which the third speed region is enlarged is selected, the speed ratio is determined, and the speed change control is performed so that the engine brake can be frequently used during the downhill. |
