1. A vehicle control device comprising:
a drive source mounted on a vehicle;
a differential device configured to distribute a driving force generated by the drive source to a right drive wheel and a left drive wheel;
a speed sensor configured to detect a rotation speed of the drive source;
a pair of wheel speed sensors configured to detect rotation speeds of the right drive wheel and the left drive wheel; and
a control device configured to set an index value having a value obtained by multiplying a value obtained by dividing the rotation speed of the drive source by a gear ratio from the drive source to the differential device by a predetermined coefficient in a case that at least one of the pair of wheel speed sensors fails, and to control torque output from the drive source based on the index value,
wherein the predetermined coefficient is set within a range of 1.9 to 2.1.
