1. A driving control device that is mounted on a vehicle including an electric motor and an internal combustion engine as power sources, the driving control device comprising:
a processor configured to:
create a speed profile that predicts a speed of the vehicle at each time;
approximate the speed profile by a predetermined approximate model and estimate a predicted amount of regenerative energy based on an approximation result, the regenerative energy being energy that is recoverable by regenerative braking of the electric motor;
set a first region and a second region in the approximation result as a region in which the vehicle travels using the electric motor, the first region being a region from a timing of starting of the vehicle until a first time has elapsed from the timing of starting of the vehicle, and the second region being a region from a predetermined timing until a timing when the regenerative energy becomes recoverable,
wherein a second time is a period from the predetermined timing to the timing when the regenerative energy becomes recoverable; and
determine the first time in the first region and the second time in the second region by allocating the predicted amount of the regenerative energy to the first region and the second region.
