A Scaling Method for Real-Time Monitoring of Mechanical Arm Admittance

Dynamic of driver arm plays an important role in the understanding of driver intentions. Combined with mechanical driving variables and human-related parameters, it allows building a road safety system based on driving intensions and could possibly provide corrections to driving mistakes. Mechanical arm admittance is a driving related parameter which represents the reaction of driver facing a steering perturbation. It is used to state driver condition. If comparison of two mechanical arm admittance amplitudes permits knowing the difference of driver condition on the two trials, monitoring a driver in real-time provides only one mechanical arm admittance data. Then a calibration is needed to know the condition of the driver. In this study, a method for scaling mechanical arm admittance is proposed. Moreover, results indicate that this calibration has to be done individually.
