DRIVING ASSISTANT SYSTEM AND METHOD HAVING WARNING FUNCTION FOR RISK LEVEL
First Claim
1. A driving assistant system having a warning function for alerting a driver of a risk level, the system comprising:
- a driving status monitoring unit configured to monitor a driver'"'"'s drowsy or careless driving;
a vehicle speed sensor configured to detect a running speed of a vehicle;
a road information providing apparatus configured to provide road information;
a reference data storage unit configured to store reference values for a risk level using output information from the driving status monitoring unit, the vehicle speed sensor, and the road information providing apparatus as a factor;
a warning output unit configured to output at least one warning message corresponding to a driver'"'"'s risk status according to a predetermined control data; and
a control unit configured to compare and calculate the output information of the driving status monitoring unit, the vehicle speed sensor, and the road information providing apparatus based on information stored in the reference data storage unit to determine a degree of driving risk and control the warning output unit according to the degree of driving risk to output a warning data which corresponds to the degree of driving risk.

Abstract
A driving assistant system and method having a warning function for alerting a driver of a risk level, which synthetically determines a running speed of a vehicle, a driver'"'"'s inattention, a road condition, and the like and provides a warning corresponding to a degree of risk (risk level) to the driver. In particular, a calculated data value corresponding to a degree of a driver'"'"'s drowsy or careless status is compared to calculation values corresponding to a vehicle speed and the degree of risk of a road to predetermined reference values corresponding to the output values and outputs at least one warning message alerting a driver of risk levels according to the comparison result.

7. A driving assistant method of performing warning function, the method comprising:
-
outputting, by a first unit, status information for a degree of a driver'"'"'s drowsiness or carelessness as a data value; detecting, by a sensor, a speed of a vehicle; determining, by a second unit, a degree of risk of a road and outputting a calculation value corresponding to the degree of risk of the road; comparing, by a control unit, output values from the outputted status information, the detected speed of the vehicle, and the determined risk level of a road to predetermined reference values set with respect to the output values; outputting, by the control unit, at least one warning message according to a comparison result of the comparing the output values; and alerting, by the control unit, a driver of a risk level based on current driving conditions associated with the preset reference value. - View Dependent Claims (8, 9, 10, 11)

12. A non-transitory computer readable medium containing program instruction executed by a controller, the non-transitory computer readable medium comprising:
-
program instructions that output status information for a degree of a driver'"'"'s drowsiness or carelessness as a data value; program instructions that detect a speed of a vehicle; program instructions that determine a degree of risk of a road and outputting a calculation value corresponding to the degree of risk of the road; program instructions that compare output values from the outputted status information, the detected speed of the vehicle, and the determined risk level of a road to predetermined reference values set with respect to the output values; program instructions that output at least one warning message according to a comparison result of the comparing the output values; and program instructions that alert the driver of a risk level based on current driving conditions associated with the preset reference value
