PROBLEM TO BE SOLVED: To provide a drive force control apparatus capable of causing a vehicle to travel in re-acceleration by setting an appropriate gear stage with the driving intention of a driver reflected.SOLUTION: A drive force control apparatus of a vehicle that is incorporated with an engine and an automatic transmission and controls drive force on the basis of a vehicular speed and an accelerator opening degree, performs: estimating, as a target vehicular speed for a re-acceleration travel after a deceleration travel of the vehicle, an expected vehicular speed desired by a driver for the re-acceleration travel, on the basis of a travel state amount in an acceleration travel prior to the deceleration travel; calculating a reacceleration-applicable acceleration to be used as a control indicator for the re-acceleration travel, on the basis of the present vehicular speed during the deceleration travel and the expected vehicular speed; setting a speed change ratio of the automatic transmission enabling the reacceleration-applicable acceleration before starting the re-acceleration travel; and updating the expected vehicular speed on the basis of the travel state amount in a case where an acceleration distance during the re-acceleration travel is longer than a given distance α (steps S104, S105).SELECTED DRAWING: Figure 12 |
