Abstract:
1. A vehicle driving force control device comprising: friction-circle limit-value estimating means configured to estimate a friction-circle limit-value as a maximum tire force which the tire is capable of exercising against a current road-surface based on an estimated tire force generated on a tire; slip rate calculating means configured to calculate a slip rate of the tire; first torque-down amount calculating means configured to calculate a first torque-down amount, as a first torque reduction amount in a state in which the tire is prevented from slipping, on the basis of a relation between the tire force and the friction-circle limit-value; second torque-down amount calculating means configured to calculate a second torque-down amount, as a second torque reduction amount in a state in which the tire is slipping, on the basis of at least the slip rate; and driving-force setting means configured to set a driving force of the vehicle by reducing a current torque in accordance with one of the first torque-down amount and the second torque-down amount.
