Abstract: A driving system for automated driving includes at least automated lateral guidance for a motor vehicle. The system is configured to determine whether one or more indications of a current or imminent manual steering intervention are present, which do not take place inadvertently and are intentional by a driver. Starting from a driving state with activated automated lateral guidance, the driving system deactivates the automated lateral guidance in response to the manual steering intervention. To deactivate the lateral guidance, a necessary steering torque operating counter to the activated lateral guidance is applied by the driver via the steering wheel within the scope of the manual steering intervention. When the at least one indication of the steering intervention intended by the driver is found to be present, the steering torque necessary to deactivate the lateral guidance is lower than when the indication of an intended steering intervention is not present.

Abstract: Techniques disclosed herein combine computer vision with eye tracking by identifying, via computer vision, safety hazards in a video captured by a camera mounted on a pair of safety glasses, and generating an alert if a user wearing the safety glasses has not (recently) noticed the hazard. Whether the user has noticed the hazard is determined based on eye tracking information extracted from a video captured by another camera that is mounted on the safety glasses and points toward the user. As a result, safety hazards may be automatically detected and reported to the user. In addition, only those hazards that have not been (recently) noticed by the user cause an alert to be generated, so the user is not distracted with unnecessary notifications.
