ABSTRACT

Increased customer acceptance requires to focus on the driver in the vehicle development. An important issue is to determine the driver’s ability to respond to situations appropriately in order to drive the vehicle safely. In this paper, a so-called driver fingerprint model has been developed which makes it possible to identify the specific driver characteristic. The fingerprint model is implemented on the vehicle as a real time application. For this purpose, relevant signals are extracted from the CAN-bus and used for modelling. Therefore longitudinal and lateral control behaviour of the driver will be analysed. Several examples of the process of determining the objective parameters are illustrated. The final fingerprint information of the driver will be used as input to adapt the thresholds of a Lane-Departure-Warning assistance system. Furthermore, based on a previous study, a comprehensive study of acceptance of the drivers for adaptive thresholds is in preparation.
