| Abstract | The state of the hands on the steering wheel is currently the most reliable indicator for evaluating the ability of the driver to control his/her vehicle. This has been confi rmed by the last release of the UNECE regulation 79, which requires a vehicle to be equipped with lane keeping assist to automatically deactivate the function if the driver is not holding the steering wheel for longer than one minute. This paper presents a detection method which, instead of relying on dedicated sensors, uses sensors already available in most mass-produced EPS systems. They are used to compute a model-based estimation of the driver torque, which is subsequently processed using a threshold and a transition time window, to determine whether or not the driver is gripping the steering wheel. |
