Abstract

A vehicle control device includes a counting unit that counts rotation of wheels by a sensor; and a rotation determination unit that determines the rotation based on a count value of each of the wheels obtained by the counting unit. Based on a movement distance of a vehicle, the movement distance of each of the wheels from rotation detection to the next rotation detection is defined as a rotation detection travel distance of each of the wheels. The rotation determination unit determines a rotation direction of a wheel a second time is a direction opposite to that detected for a first time when rotation detection is not performed even once for a first reference wheel having a rotation detection travel distance equal to or less than a rotation detection travel distance of the first determination target wheel while the rotation of the selected first determination target wheel is detected twice.
