1. A rollback prevention control device for an electrically driven vehicle capable of traveling by transmitting driving force from a rotation electric machine to wheels with the wheels being braked by regenerative braking by a load associated with electric generation of the rotation electric machine and a frictional braking on an as required basis, comprising:

  • a charging restriction detecting unit that detects that charging to the rotation electric machine is being restricted;

    a starting operation detecting unit that detects a starting operation of a driver of the electrically driven vehicle;

    a vehicle rollback detecting unit that detects if the vehicle rolls back in a direction opposite to a starting direction when the starting detecting unit has detected the starting operation; and

    a frictional braking control unit that causes the frictional braking to occur and to control a frictional braking force to a braking force in accordance with the starting operation when the starting detecting unit and the vehicle rollback detecting unit detect the vehicle rollback at the starting operation and the charging restriction unit detects restriction of a charging operation.
