Cruise control device

A cruise control device applied to a vehicle including an imaging device that captures a view ahead of an own vehicle in a traveling direction, the cruise control device comprising:

• a position acquisition unit that acquires a position of a preceding vehicle traveling ahead of the own vehicle in the traveling direction, based on image information captured by the imaging device;
• a track generation unit that generates a track of the preceding vehicle, based on the position of the preceding vehicle acquired by the position acquisition unit;
• a following travel control unit that performs following travel control for following the preceding vehicle by calculating an amount of control for causing the own vehicle to travel along the track of the preceding vehicle generated by the track generation unit and by causing the own vehicle to travel, based on the calculated amount of control;
• and
• a broad classification unit that broadly classifies the preceding vehicle as a motorcycle or other type of vehicle, wherein:
• if the preceding vehicle is classified as the motorcycle by the broad classification unit, the following travel control unit calculates the amount of control such that an curvature variation of a track of the own vehicle under the following travel control is smaller than in a case where the preceding vehicle is classified as another type of vehicle by the broad classification unit.
