SYSTEM AND METHOD FOR DETERMINING VEHICLE DRIVING STATUS INFORMATION-BASED DRIVING CONCENTRATION
First Claim
1. A system for determining driving concentration of a vehicle driver, the system comprising:
- a steering angle sensor configured to sense displacement of a steering wheel;
a front camera sensor configured to sense an object on a road and within a predetermined area in front of a vehicle;
a data storage unit configured to store data provided from the steering angle sensor and the front camera sensor at a predetermined time interval, accumulate a value calculated by an index calculation unit and manage the accumulated value as a standard value, according to a predetermined control data;
the index calculation unit configured to calculate a quantitative index configured to recognize a vehicle'"'"'s status based on data stored in the data storage unit according to a predetermined control data;
a statistic processing unit configured to statistically process the value calculated by the index calculation unit and output status information which is an index for determining driving concentration; and
a driving concentration determination unit configured to sequentially control the index calculation unit and the statistic processing unit based on the data stored in the data storage unit to calculate the status information and compare the calculated status information to the standard value stored in the data storage unit to determine a driver'"'"'s level of driving concentration.

Abstract
A method and system for determining driving concentration which is capable of analyzing a driver'"'"'s driving concentration on the basis of variation of a steering angle and driving status information of a vehicle acquired from a front camera sensor. The method includes storing output data of a steering angle sensor and a front camera sensor mounted in a vehicle at a predetermined time interval, calculating a quantitative index include a value for recognizing a vehicle status based on information stored in a storage unit, statistically processing the calculated value to output status information which is an index for determining driving concentration, and comparing the information calculated in the statistically processing to the predetermined reference data and determining the driving concentration according to the comparison result.
