Abstract

The purpose of the present invention is to improve fuel efficiency during coasting by calculating, with high accuracy, travel resistance during coasting. This vehicle control device comprises: a first travel resistance acquisition unit that acquires a first travel resistance, which is determined on the basis of road information or external information; and a second travel resistance acquisition unit that acquires a second travel resistance, which is determined on the basis of the result of actual traveling of the vehicle. This vehicle control device determines the content of coasting travel control during traveling of the vehicle on the basis of the result of a comparison of the first travel resistance and the second travel resistance in a predetermined zone where the vehicle has actually traveled.
