A drive device for a hybrid electric vehicle is provided with an engine ( 2 ) connected to a planet carrier (C) of a planetary gear set ( 1 ), a first motor/generator ( 3 ) and drive wheels ( 8 ) connected to a ring gear (R), a second motor/generator ( 4 ) connected to a sun gear (S), and a battery ( 24 ) that is electrically connected to the first motor/generator ( 3 ) and to the second motor/generator ( 4 ). When a failure of the first motor/generator ( 3 ) or the second motor/generator ( 4 ) is detected, a controller ( 21 ) restricts rotation (S 5 , S 105 ) of the second motor/generator ( 4 ), through a clutch ( 11 ), thus assuring running of the vehicle and charging of the battery ( 24 ) by engine output.
