PROBLEM TO BE SOLVED: To appropriately cool a generator and suppress an increase in power consumption.SOLUTION: While stop-time generation control is carried out, output ratios Phi, Pmid, and Plo that are ratios of times for Hi drive, Mid drive, and Lo drive on the assumption that an electric pump of a cooling device, which cools two motors and inverters for controlling the respective motors, is driven according to a predetermined driving pattern during a predetermined time tref, are set based on an inputted battery current Ib of a battery (steps S100 to S110), and random output control is carried out in order to control the electric pump so that the electric pump 66 is driven at the set output ratios Phi, Pmid, and Plo(step S120). Accordingly, the two motors and the inverters for controlling the respective motors can be appropriately cooled, and an increase in power consumption can be suppressed. |
