1. A driving assistance system for a vehicle, comprising:
- a traveling condition detection unit configured to detect a traveling condition of a vehicle;
a drive operation detection unit configured to detect a drive operation by a driver;
a storage unit configured to store data of the traveling condition detected by the traveling condition detection unit and the drive operation detected by the drive operation detection unit; and
a drive diagnosis unit configured to estimate driving characteristics of the driver using data with a limited temporal position and range which are stored in the storage unit among data of the traveling condition detected by the traveling condition detection unit and the drive operation detected by the drive operation detection unit, and diagnoses drive operation of the driver based upon the estimated driving characteristics, wherein;
the drive diagnosis unit is configured to;
obtain data of a first period of time and data of a second period of time from the data stored in the storage unit of the traveling condition detected by the traveling condition detection unit and the drive operation detected by the drive operation detection unit;
update in real time the data of the first period of time and the data of the second period of time;
perform a comparison of the data of the first period of time with the data of the Second period of time; and
diagnose drive operation of the driver based on the comparison,wherein the data of the first period of time represents a current traveling condition and drive operation,wherein the data of the second period of time represents a traveling condition and drive operation of the current day and include the current traveling condition and drive operation, the second period of time being longer than the first period of time.

Abstract
A driving assistance system for vehicle detects short-duration data representing a current traveling condition and drive operation, and intermediate-duration data representing a travelling condition and drive operation of this day. Drive diagnosis is carried out by comparing distribution of the short-duration data and distribution of the intermediate-duration data.

21. A driving assistance method for a vehicle, comprising:
-
detecting a traveling condition of a vehicle via a traveling condition detection unit; detecting a drive operation by a driver; storing into a storage unit data of the detected traveling condition and the detected drive operation; and estimating, via a controller, driving characteristics of the driver using data with a limited temporal position and range which are stored in the storage unit among data of the detected traveling condition and the detected drive operation, and, based on the estimated driving characteristics, diagnosing drive operation of the driver;
wherein;the diagnosing the drive operation of the driver comprises; obtaining data of a first period of time and data of a second period of time from the data stored in the storage unit of the detected traveling condition and the detected drive operation; updating in real time the data of the first period of time and the data of the second period of time; performing a comparison of the data of the first period of time with the data of the second period of time; and diagnosing the drive operation of the driver based on the comparison, wherein the data of the first period of time represents a current traveling condition and drive operation, wherein the data of the second period of time represents a traveling condition and drive operation of the current day and include the current traveling condition and drive operation, the second period of time being longer than the first period of time.
