System and method of detecting drowsy driving

摘要

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.

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; and comparing, by the controller, the current thresholds and the current characteristics to determine whether drowsy driving is generated, wherein the basic characteristic and the current characteristic are any one of a limitation of a range of a maximum value and a minimum value of the information, evaluation of an inclination, and analysis of a frequency.
