Estimation of a Driver's Stress based on Steering Admittance Measurement

In recent years, an increasing amount of research on advanced driver assistant system (ADAS) has been reported. To improve the performance of ADAS, the system should be adaptive to the change of conditions of drivers and there is a need to be able to get accurate, non-evasive estimates of driver neuromuscular admittance. From previous researches, correlation between grip strength and driver’s stress is shown. Also, correlation between human admittance and grip strength is shown. From these two facts, estimation of admittance can be used for non-evasive estimation of driver’s stress. Steering admittance somehow reflects driver’s intention, while a driver holds the steering wheel. In this research a method of admittance measurement using sensors of power steering system is proposed and its performance is examined through an experiment using a driving simulator. Admittance is estimated from measured feedback torque of power steering and steering wheel angle, and its feasibility is shown in a case of highway entrance and passing situations.
