Abstract
A method is disclosed for providing an indication that a vehicle has exceeded a safe driving speed. The speed and position of an obstacle are combined with a driver reaction time to arrive at a safe maximum speed. The driver reaction time is predicted based not only on generic values as in known systems, but also on at least one scaling factor which can be, for example, a scaling factor which penalises increased driving duration, or driver age, or experience, or weather conditions.
