Driver operation prediction device, method, and driver operation prediction program

A recording medium storing a program that causes a computer to function as:

• a target destination point deviation angle detection unit that detects a deviation angle between a progression direction of a vehicle, and a direction of a target destination point after a predetermined forward gaze duration on a target course being travelled by the vehicle;
• and
• a yaw angular speed prediction unit that predicts a yaw angular speed proportional to the deviation angle detected by the target destination point deviation angle detection unit, as a yaw angular speed realized by steering wheel operation by a driver after a predetermined lag time for matching a timing of change in vehicle movement to a timing of change in curvature of the target course.

A driver operation prediction method comprising:

• detecting a deviation angle between a progression direction of a vehicle, and a direction of a target destination point after a predetermined forward gaze duration on a target course being travelled by the vehicle;
• and
• predicting a yaw angular speed proportional to the detected deviation angle, as a yaw angular speed realized by steering wheel operation by a driver after a predetermined lag time for matching a timing of change in vehicle movement to a timing of change in curvature of the target course.
