TRAVEL CONTROL DEVICE, TRAVEL CONTROL METHOD, AND TRAVEL CONTROL PROGRAM

A travel control device is provided as a vehicle control ECU for controlling a travel of a vehicle. The vehicle control ECU includes: a resistance estimator estimating a cornering resistance, which is a travel resistance acting on the vehicle in a curved travel section where a curved travel of the vehicle is scheduled; a correction determiner determining whether the cornering resistance is out of an allowable resistance range; and a correction setter setting a correction amount when it is determined that the cornering resistance is out of the allowable resistance range.
