Vehicle control device, storage medium for storing computer program for vehicle control, and method for controlling vehicle

A computer-readable, non-transitory storage medium storing a computer program for vehicle control, which causes a processor execute a process, the process comprising:

• determining a set speed for a vehicle representing a target speed for the vehicle while the vehicle is traveling, based on the speed limit of a road representing an upper allowable limit for traveling on the road on which the vehicle is traveling, and a current correction value corresponding to the speed limit of the road;
• counting a number of changes the set speed for the vehicle has been changed by a driver;
• and
• calculating a new correction value for the set speed for the vehicle based on a correction coefficient determined based on the number of changes, and speed difference between the set speed for the vehicle after change and the speed limit of the road on which the vehicle is traveling, each time the number of changes has been counted,
• wherein the next set speed for the vehicle is determined based on the speed limit of the road on which the vehicle is traveling and the new correction value corresponding to the speed limit of the road.

A method for controlling a vehicle carried out by a vehicle control device and the method comprising:
