Abstract
A driver assistance device, a driver assistance method, and a driver assistance system according to the present invention make it possible to: determine a distribution of a risk of a vehicle departing from a drivable width of a road on which the vehicle travels based on driving environment factors including a road curvature and a friction coefficient of a road surface of a curve approaching the vehicle; calculate an operation variable of an actuator related to a steering operation of the vehicle based on the distribution of the risk; and output the operation variable to the actuator. This enables steering control based on potential risk evaluation made by taking into account a risk that the controllability of the vehicle may decrease when the vehicle travels on a curve.
