Driving concentration level calculating apparatus and method, and system and method for warning of vehicle collision using the same

摘要

A driving concentration level calculating apparatus is provided and includes a controller configured to acquire an acceleration of a traveling vehicle and measure a relative velocity to a preceding vehicle. In addition, noise is removed from the acquired acceleration of the traveling vehicle and from the measured relative velocity to the preceding vehicle. A plurality of correlation values are calculated based on the acceleration of the traveling vehicle and the relative velocity to the preceding vehicle from which noise has been removed. In addition, the controller is configured to detect a time at which a maximum correlation value is calculated as a driving concentration level from among the calculated correlation values.

1. A driving concentration level calculating apparatus comprising:
a memory configured to store program instructions; and a processor configured to execute the program instructions, the program instructions when executed configured to:
acquire an acceleration of a traveling vehicle;measure a relative velocity to a preceding vehicle;remove noise from the acquired acceleration of the traveling vehicle;remove noise from the measured relative velocity to the preceding vehicle;calculate correlation values based on the acceleration of the traveling vehicle and the relative velocity to the preceding vehicle from which noise has been removed; anddetect a time at which a maximum correlation value is calculated as a driving concentration level from among the calculated correlation values,wherein the correlation values are calculated by setting a relative velocity window and an acceleration window for the relative velocity of the preceding vehicle and the acceleration of the traveling vehicle, respectively, wherein the relative velocity window and the acceleration window having substantially the same time range with respect to a current time point, and by moving the relative velocity window to a past direction by unit time to calculate the correlation values sequentially, with the acceleration window fixed.
