First Claim
Patent Images
1. An apparatus for assisting safe operation of a vehicle, the vehicle having a vehicle environment, the apparatus comprising:
- an environment sensor system, operable to detect hazards within the vehicle environment and to provide hazard data;
a driver monitor, operable to provide driver awareness data, the driver awareness data including a gaze track; and
an attention-evaluation module, identifying perceived hazards and unperceived hazards by comparing the hazard data and the gaze track,the attention-evaluation module providing an alert signal relating to the unperceived hazards.

Abstract
An apparatus for assisting safe operation of a vehicle includes an environment sensor system detecting hazards within the vehicle environment, a driver monitor providing driver awareness data (such as a gaze track), and an attention-evaluation module identifying hazards as sufficiently or insufficiently sensed by the driver by comparing the hazard data and the gaze track. An alert signal relating to the unperceived hazards can be provided.
