Abstract
In this research, we propose the concept of the "QOD (The Quality Of Driving)". We have already established the method for quantifying the state of driving, and then estimate the "QOD". To evaluate the "QOD" of the driving state in actual urban road and expressway, we adopted three parameters: the degree of the meandering, the stability of the acceleration, and the sufficiency of the distance between own vehicle and the vehicle ahead, hi our system, we measure these parameters from the sequence of images taken by the camera placed on the dashboard of our vehicle, and velocity sensor and yaw rate sensor. Finally we evaluate the "QOD". This method has been tested on expressways and urban road. As a result, it is presented that our system can evaluate the stability of driving condition and warn the driver when the driving was not stable.
