Abstract:
1. A vehicle driving force control device comprising: first-tire-force estimating means configured to estimate a tire force to be generated on a wheel based on a request from a driver as a first tire force; second-tire-force estimating means configured to estimate a tire force currently being generated on the wheel as a second tire force; friction-circle limit-value setting means configured to set a friction-circle limit-value of a tire force; first-excessive-tire-force estimating means configured to estimate a tire force exceeding the friction-circle limit-value on the basis of the first tire force and the friction-circle limit-value as a first excessive tire force; second-excessive-tire-force estimating means configured to estimate a tire force exceeding the friction-circle limit-value on the basis of the second tire force and the friction-circle limit-value as a second excessive tire force; and driving-force correcting means configured to correct a driving force on the basis of the first excessive tire force and the second excessive tire force.
