A control device 10 for a vehicle has a hill ascent angle update determiner 74, a slope estimator 76, a deceleration determiner 78, and a hill ascent angle estimator 80. The deceleration determiner 78 determines that a vehicle 12 is in a deceleration state when the throttle opening is equal to or lower than a threshold TH. The hill ascent angle update determiner 74 prohibits update processing of an estimated hill ascent angle ¸ in the increase direction by the hill ascent angle estimator 80 if the slope estimator 76 estimates that a road surface 92 has an upward slope and the deceleration determiner 78 determines that the vehicle 12 is in the deceleration state. This prevents erroneous operation of an ECU if a brake detector has failed, and enables control of an automatic transmission in conformity with the intention of a driver. |
