<P>PROBLEM TO BE SOLVED: To provide a drive control device for an electrically-propelled vehicle suppressing a driving wheel slip with high responsiveness in the occurrence of a driving wheel slip, and suppressing generation of vibration and failure of a drive source and equipment interlocked with the drive source. <P>SOLUTION: In an integral controller 10 of the drive control device for an electrically-propelled vehicle, during execution of torque capacity control, if it is determined that there is a driving wheel slip, when a target clutch downstream rotational frequency is larger than a clutch upstream minimum rotational frequency, a clutch transmission torque capacity is maintained at a transmission torque capacity responding to demanded driving force, and a motor generator MG is controlled such that a clutch upstream rotational frequency is equal to the target clutch downstream rotational frequency. On the other hand, when the target clutch downstream rotational frequency is smaller than the clutch upstream minimum rotational frequency, the clutch upstream rotational frequency is maintained at the clutch upstream minimum rotational frequency or more, and driving wheel slip control of controlling the clutch transmission torque capacity such that a clutch downstream rotational frequency matches the target clutch downstream rotational frequency is executed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
