Abstract
A vehicle control device includes a slippage determination unit, a control unit, a different-diameter determination unit and a threshold adjuster. The slippage determination unit determines that a drive wheel is slipping when an index value that is correlated with a rotation speed of the drive wheel exceeds a threshold. The control unit controls a driving force of the drive wheel such that the index value matches a target value when it is determined that the drive wheel is slipping. The different-diameter determination unit determines whether a different-diameter tire that has a different diameter from a reference diameter is mounted on the drive wheel. The threshold adjuster adjusts a threshold on the basis of a ratio between a diameter of the tire mounted on the drive wheel and the reference diameter when it is determined that the different-diameter tire is mounted on the drive wheel.
