1. An automated driving assistance apparatus comprising:
an occupant's emotion learning section configured to, during a manual driving mode,
collect data sets each including driving state information of a vehicle, surrounding environment information of the vehicle, and emotion information of an occupant of the vehicle associated with each other, and
train an occupant's emotion model on a basis of the data sets, the occupant's emotion model being used to estimate an emotion of the occupant from a driving state of the vehicle;
a control parameter setting section configured to: during an automated driving mode,
select one of the data sets based on a current surrounding environment and a target emotion, the selected one of the data sets including emotion information closest to the target emotion,
generate values based on (1) driving state information from the selected one of the data sets and (2) current driving state information of the vehicle;
estimate emotions of the occupant corresponding to the values, respectively, using the occupant's emotion model;
determine one of the estimated emotions of the occupant that is closest to the target emotion among the estimated emotions;
select one of the values that corresponds to the determined one of the estimated emotions of the occupant; and
convert the selected one of the values to a control parameter for automated driving control of the vehicle; and
a vehicle controller configured to control automated driving of the vehicle using the control parameter.
