An output control device (1) configured to control the output of a running drive source mounted on a vehicle includes an anomaly discriminator (32) which judges that the output control device (1) is anomalous, if excess acceleration G, also output difference index, of the vehicle remains greater than or equal to a predetermined threshold value (G1, ..., G7) for a predetermined time (t1, ..., t7) or longer, wherein the predetermined time (t1, ..., t7) for the anomaly discrimination is set so as to shorten with increase in the threshold value (G1, ..., G7) of the excess acceleration of the vehicle.
