1. A wobble determination device comprising:
a steering determination unit configured to determine whether a driver of a vehicle performs sudden steering and performs sudden return steering over a steering position at the beginning of the sudden steering in a direction opposite to a direction of the sudden steering after the sudden steering; and a wobble determination unit configured to determine that the vehicle wobbles if the amount of sudden return steering is equal to or greater than a predetermined value within a predetermined period of time, when the steering determination unit determines that the steering of the driver is the sudden return steering which is performed over the steering position at the beginning of the sudden steering, wherein, when a time interval from a time when a steering input is the maximum during the sudden steering to a time when a steering input is the maximum during steering which is performed in the direction opposite to the direction of the sudden steering is equal to or less than a predetermined value, the steering determination unit determines that the steering in the opposite direction is the sudden return steering.
