Embodiment approach

[0044] figure 1 is an exemplary block diagram of a driving attention level calculation device for calculating a driving attention level according to an exemplary embodiment of the present invention. Such as figure 1As shown, the driving attention level calculation device may include a plurality of units executed by a controller having a processor and memory. The plurality of units may include a network communication unit 10 , a relative information measurement unit 20 , a noise removal unit 30 , a correlation value calculation unit 40 , and a driving attention level detection unit 50 .

[0045] Specifically, the network communication unit 10 may include an interface connected to a vehicle network to obtain the speed and acceleration (eg, longitude acceleration) of a running vehicle (eg, a vehicle being driven) via the vehicle network. The expression "driving vehicle" refers to a vehicle in which a driving attention level calculation device is installed. Additionally, the ve...

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application is based on and claims priority from Korean Patent Application No. 10-2013-0105440 filed with the Korean Intellectual Property Office on Sep. 3, 2013, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] The present invention relates to a driving attention level calculation device and method, and a system and method for warning of a vehicle collision using the driving attention level calculation device. More specifically, the present invention relates to adjusting the timing of a collision warning in consideration of a driver's driving attention level when a time to collision inverse (TTCi) exceeds a threshold value. Background technique [0004] Today, with the assistance of information and communication technologies, vehicles have evolved into smart vehicles that provide improved safety and convenience. Since these smart vehicles require various types...
