Vehicle driver condition e.g. fatigue, determining method, involves developing probabilistic model representing cumulated probabilities, and determining condition as driver condition based on cumulated probabilities using model

摘要

The method involves combining values of sensors in a data packet within a time period. Statistical information in the form of a set of indicator values is determined using the sensor values, and another set of indicator values is obtained within another time period. Probabilities of possible conditions of a driver are found based on comparison of a distribution of the latter set with a reference model. A probabilistic model representing cumulated probabilities is developed. One of the conditions is determined as a driver condition based on the probabilities using the probabilistic model. Independent claims are also included for the following: (1) a computing device for determining a driver condition of a vehicle (2) a computer program for determining a driver condition of a vehicle.
