In a vehicle driving-force control device, if a primary speed is not lower than or equal to a kick-down allowable speed and an accelerator pedal depression amount is larger than or equal to a kick-down allowable depression amount, a shift control device identifies an intention of acceleration from a driver's accelerator operation and kick down a gear stage to a lower stage, even in a manual shift mode having been selected. In this case, the kick-down allowable speed is set to a different value for each of driving force characteristic modes, and a speed range in which a kick-down operation is allowed to be automatically performed on the basis of the primary speed is set narrower for a driving force characteristic mode having higher responsiveness to an accelerator operation.
A vehicle driving-force control device having an automatic shift mode in which a gear ratio or a gear stage is automatically controlled according to a preset shift characteristic and a manual shift mode in which one of a plurality of gear stages can be manually selected for controlling an automatic transmission constituting a power train, the vehicle driving-force control device comprising:
