METHOD AND APPARATUS FOR GENERATING AN INDICATOR OF A RISK LEVEL IN OPERATING SYSTEMS

摘要

A method and apparatus for generating an indicator of a risk level in motor vehicle and notifying vehicle systems when a risk level is above a specific threshold includes, receiving a plurality of driver distraction indicators, assigning a weighting value to each indicator, applying a scaling factor to the weighting value assigned to those indicators which are identified as being related, and summing the weighting values to produce an output value indicating a risk level. Distraction indicators can include on-board system and sensor outputs and stored data relating to driver attributes. Related indicators may comprise those distraction indicators relating to environmental conditions (eg. rain and low ambient light levels), or to vehicle performance to driver concentration level (eg. in-car phone and navigation system). The scaling step allows the weighting process to be refined based on the status of other received indicators.

1. A method for generating an indicator of a risk level in an operating system, the method comprising:
receiving distraction indicators, from one or more sensors or processors, wherein at least one of said distraction indicators is designated as being related to at least one other of said distraction indicators; assigning a weighting value to each of said distraction indicators; identifying distraction indicators which are related; modifying, by a scaling factor, the weighting values assigned to those distraction indicators which are identified as being related; and summing the weighting values of the distraction indicators to produce an output value indicating a risk level.
