Real-time identification method of driver model with steering manipulation

Development of a Steering Entropy Method for Evaluating Driver Workload

The authors have developed a steering entropy method to easily and accurately quantify the workload imposed on drivers who are engaged in activities apart from the normal driving operations of longitudinal and lateral control. A driver's steering behavior tends to become more discontinuous while performing an activity in addition to driving. To quantify these discontinuities, steering entropy v...

Real-time manipulation with magnetically tunable structures.

Magnetically tunable micropillar arrays with uniform, continuous and extreme tilt angles for real-time manipulation are reported. We experimentally show uniform tilt angles ranging from 0° to 57°, and develop a model to accurately capture the behavior. Furthermore, we demonstrate that the flexible uniform responsive microstructures (μFUR) can dynamically manipulate liquid spreading directionali...

Real Time Driver Safety System

Automatic car steering control bridges over the driver reaction time

Abstract: A car driver needs at least five hundred milliseconds before he can react to unexpected yaw motions. During this time the uncontrolled car may produce a dangerous yaw rate and sideslip angle. Automatic steering control for disturbance rejection is designed such that it bridges over the driver reaction time, but returns the full steering authority to the driver thereafter. The solution...

Identification of driver model parameters.

The paper presents a driver model, which can be used in a computer simulation of a curved ride of a car. The identification of the driver parameters consisted in a comparison of the results of computer calculations obtained for the driver-vehicle-environment model with different driver data sets with test results of the double lane-change manoeuvre (Standard No. ISO/TR 3888:1975, International ...
