A travel control apparatus (140) includes a acquisition unit (141), which acquires information on a target track through which a vehicle (M) will pass in the future, a parameter determiner (142), which determines a parameter by which a track model defined by one or more parameters coincides with a track acquired by the acquisition unit, and a steering controller (143), which feedforward-controls steering of the vehicle on the basis of at least the track model defined by the parameter determined by the parameter determiner, wherein the parameter determiner determines the parameter on the basis of a direction of a change in the degree of separation between the track model and the target track with respect to a change in the parameter.
