Embodiment Construction

[0082] Distraction and situational awareness

[0083] To safely and efficiently maneuver a motor vehicle, a driver must continuously receive sensory input from many different sources and respond to those inputs appropriately and in a timely manner. There is an element of cumulative workload associated with user participation in automated dialogs, and this factor is addressed in the present invention.

[0084] If the cognitive workload of managing inputs and responses exceeds a certain level, the driver may be distracted from the driving task, with potentially serious consequences. However, the person who is the nominal "driver" of the autonomous vehicle does not have the same responsibilities being performed. The term "autonomous vehicle" herein refers to a vehicle that has one or more autonomous systems to perform one or more common driving tasks without direct driver involvement. Examples of systems for autonomous vehicles include, but are not limited to: automatic pilot...

Abstract

Methods and systems for reducing driver distraction and situation non-awareness related to a dialogue of an automated dialogue system in a vehicle. For a dialogue policy learning session, driver distraction is introduced as an input into a penalty assigner that assesses dialogue quality, and dialogue acts are extended to include dialogues and dialogue act presentation styles which reduce driver workload related to dialogues. The automated dialogue system policy is developed during the learning process by optimizing the penalties, so that automated dialogue workload is reduced in response to increased workload or anticipated workload on the driver. Methods and systems are presented for responding to both actual workload in regular vehicles as well as anticipated workload in autonomous vehicles.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 652,600, filed May 29, 2012, entitled "Reducing Distraction During Driver Spoken Conversations," the contents of which are hereby incorporated by reference Priority to this provisional patent application is pending and is hereby claimed pursuant to 37 CFR 1.78(a)(4) and (5)(i). Background technique [0003] Drivers of motor vehicles may experience distraction in certain situations, often characterized by increased mental workload. In a vehicle capable of autonomous operation there occurs a situation in which the nominal driver may lose situational awareness, which may be unsafe under certain expected workload conditions requiring driver response. Automated speaking and multimodal dialog systems are becoming increasingly common in motor vehicles and can be a factor in reducing a driver's potential distraction and / or reduced situational awa...
