DRIVING ASSISTANCE DEVICE AND RECORDING MEDIUM

A driving assistance device reflects, in autonomous driving control on a vehicle, a driving characteristic of a driver who drives the vehicle learned during manual driving of the vehicle. The driving assistance device includes a storage that stores information on an individual risk potential set for the vehicle by learning a risk sensed by the driver for each of one or more obstacles during the manual driving, a vehicle risk calculator that sets, for the vehicle, a vehicle risk map that reflects the individual risk potential of an occupant of the vehicle during autonomous driving of the vehicle, and a driving condition setter that sets a driving condition for the autonomous driving of the vehicle based on information on the vehicle risk map and information on an obstacle risk map that reflects an obstacle risk potential set for the each of the one or more obstacles.
