SYSTEM AND METHOD OF DETECTING DROWSY DRIVING
First Claim
1. A method of detecting drowsy driving, comprising:
- calculating, by a controller, basic characteristics based on steering torque information and lateral displacement information for every first time;
calculating, by the controller, basic thresholds based on the basic characteristics for a second time;
calculating, by the controller, a current characteristic based on the steering torque information and the lateral displacement information for every third time;
calculating, by the controller, current thresholds based on the current characteristics for a fourth time andcomparing, by the controller, the current thresholds and the current characteristics to determine whether drowsy driving is generated.

Abstract
A system and method of detecting drowsy driving that include a controller configured to calculate basic characteristics based on steering torque information and lateral displacement information for every first time and basic thresholds based on the basic characteristics for a second time. In addition, the controller calculates a current characteristic based on the steering torque information and the lateral displacement information for every third time and calculates current thresholds based on the current characteristic for a fourth time. The controller then compares the current thresholds and the current characteristics to determine whether drowsy driving is generated.
