DETERMINATION APPARATUS AND DETERMINATION METHOD

A determination apparatus includes a distance acquisition part that acquires a longitudinal distance in a traveling direction of a host vehicle between a preceding vehicle that the host vehicle is following and the host vehicle, and a determination part that determines, as a target turning curvature, a curvature that is smaller than a predetermined curvature if the longitudinal distance is less than a determination distance corresponding to a maximum curvature at which the host vehicle can turn.
