Abstract
Provided is a drive source control device that can suppress increase in the rotation speed of a drive source. This drive source control device () includes: an overspeed determination module () to determine whether the rotation speed of each of two drive sources (L,R) is overspeed; and a correction module () to, when the overspeed determination module () determines that the rotation speed of at least one of the drive sources is overspeed, correct command values for outputs of the two drive sources, supplied from a command module (). The correction module () corrects the command values of the outputs of the two drive sources (L,R) so that the torque of the drive wheel having greater rotation speed decreases from the torque before the correction, and the torque of the drive wheel having smaller rotation speed maintains or decreases from the torque before the correction.
