Abstract
A driving support device includes: a trajectory deriving unit configured to derive a reference trajectory in a predetermined section corresponding to a predetermined curve shape; a frequency deriving unit configured to derive a first frequency which is determined according to a frequency component of a steering angle of a vehicle when it is assumed that the vehicle has passed through the predetermined section along the reference trajectory; a detection value acquiring unit configured to acquire a detection value of the steering angle; a component deriving unit configured to derive a frequency component of the steering angle acquired in the predetermined section when the vehicle has passed through the predetermined section; and a driving support unit configured to determine a driving support operation for a driver of the vehicle on the basis of a result of comparison between an integrated value of the frequency component in a first band equal to or greater than the first frequency and equal to or less than a second frequency and a first reference value.
