This paper reports preliminary work on an experimental vehicle and simulators and their initial use towards the development of driver adaptive warning and assistance systems that will be triggered by driver inattention monitor in the Drive Safe national consortium project in Turkey. Determination of driver inattention based on visual, sound and driving input data collected from the driver while driving on a test route or its replication in a simulator environment is conducted by the other research groups in the consortium and is not presented here. The paper first gives information about the Drive Safe project and its goals and concentrates on the construction of a data acquisition vehicle used for driver modelling, preliminary work on simulators used for development and testing in the lab, and initial work on development of warning and assistance systems. The warning systems considered are collision risk warning and rollover risk warning. The assistance systems considered are collision avoidance assistance and dynamic stability enhancement assistance, which includes yaw and roll dynamics stability augmentation. Preliminary results are given in the paper on the experimental vehicle and simulators and driver warning and assistance systems. Copyright © 2010 Inderscience Enterprises Ltd.
