Abstract
A drowsy driving management device includes: a processor configured to determine whether slow eye movement of a user occurs and whether there is no change in steering torque and to determine that the user drives while drowsy when the slow eye movement of the user occurs and when there is no change in the steering torque for a predetermined period of time; and a storage that stores information indicating whether the slow eye movement occurs and a result of determining whether there is no change in the steering torque.
Claims16
A drowsy driving management device, comprising:
- a processor configured to:
- determine whether slow eye movement of a user occurs and whether there is no change in steering torque, and
- determine that the user drives while drowsy when the slow eye movement of the user occurs and when there is no change in the steering torque for a predetermined period of time;
- and
- a storage storing information indicating whether the slow eye movement occurs and a result of determining whether there is no change in the steering torque,
- wherein the processor is configured to:
- calculate first eye movement information with respect to a vehicle based on information about a fixation of the user and information about a head pose of the user based on image data, and
- calculate second eye movement information with respect to an external environment based on the first eye movement information,
- wherein the information about the fixation includes a gaze yaw angle and a gaze pitch angle, and
- wherein the information about the head pose includes a head pose yaw angle and a head pose pitch angle.
A vehicle system, comprising:
- a drowsy driving management device configured to:
- determine whether slow eye movement of a user occurs and whether there is no change in steering torque, and
- determine that the user drives while drowsy when the slow eye movement of the user occurs and when there is no change in the steering torque for a predetermined period of time;
- and
- a warning device configured to output a warning to the user, when it is determined that the user drives while drowsy,
- wherein the drowsy driving management device is configured to:
- calculate first eye movement information with respect to a vehicle based on information about a fixation of the user and information about a head pose of the user based on image data, and
- calculate second eye movement information with respect to an external environment based on the first eye movement information,
- wherein the information about the fixation includes a gaze yaw angle and a gaze pitch angle, and
- wherein the information about the head pose includes a head pose yaw angle and a head pose pitch angle.
A drowsy driving management method, comprising:
- determining whether slow eye movement of a user occurs and whether there is no change in steering torque;
- and
- determining that the user drives while drowsy, when the slow eye movement of the user occurs and when there is no change in the steering torque for a predetermined period of time,
- wherein the determining whether slow eye movement of a user occurs and whether there is no change in steering torque includes:
- calculating first eye movement information with respect to a vehicle based on information about a fixation of the user and information about a head pose of the user based on image data;
- and
- calculating second eye movement information with respect to an external environment based on the first eye movement information,
- wherein the information about the fixation includes a gaze yaw angle and a gaze pitch angle, and
- wherein the information about the head pose includes a head pose yaw angle and a head pose pitch angle.
