1. A driving assistance apparatus for a vehicle, comprising:
one or more memories; and
circuitry that performs, when the vehicle is traveling under an autonomous driving mode, operations including:
detecting, using at least a sensor, a psychological state that reflects a degree of nervousness and concentration of the driver on an activity,
ranking a level of the nervousness and the concentration of the driver on the activity,
determining, based on driving information indicating driving conditions of the vehicle, whether the autonomous driving mode is continuable for a period of time, and
when it is determined that the autonomous driving mode is not continuable for the period of time, determining, based on the psychological state and the ranking, a method of presenting, in the vehicle, a take-over request that informs the driver that the autonomous driving mode is going to be cancelled.
