1. A driving assistance device comprising:
processing circuitry configured to
acquire environmental information on an environment around a mobile object;
acquire action information on an action of a driver of the mobile object;
obtain control information for performing automated driving control of the mobile object on a basis of the acquired environmental information and a machine learning model that uses the environmental information as an input and outputs the control information;
determine contribution information having a high degree of contribution to the control information on a basis of the acquired environmental information and the obtained control information;
calculate cognitive information indicating a cognitive region of the driver in the environment around the mobile object on a basis of the acquired action information and the acquired environmental information;
specify unrecognized contribution information estimated not to be recognized by the driver on a basis of the determined contribution information and the calculated cognitive information; and
output driving assistance information necessary for driving assistance on a basis of the unrecognized contribution information that has been specified.
