• Abstract summary: This study focuses on the development of contextual, semantically meaningful representations of the driver state. We conduct a large-scale real-world controlled data study where participants are instructed to take-over control from an autonomous agent. These take-over events are captured using multiple driver-facing cameras, which when labelled result in a dataset of control transitions and their corresponding take-over times (TOTs) After augmenting this dataset, we develop and train TOT models that operate sequentially on low and mid-level features produced by computer vision algorithms operating on different driver-facing camera views.

• Abstract: With increasing automation in passenger vehicles, the study of safe and smooth occupant-vehicle interaction and control transitions is key. In this study, we focus on the development of contextual, semantically meaningful representations of the driver state, which can then be used to determine the appropriate timing and conditions for transfer of control between driver and vehicle. To this end, we conduct a large-scale real-world controlled data study where participants are instructed to take-over control from an autonomous agent under different driving conditions while engaged in a variety of distracting activities. These take-over events are captured using multiple driver-facing cameras, which when labelled result in a dataset of control transitions and their corresponding take-over times (TOTs). After augmenting this dataset, we develop and train TOT models that operate sequentially on low and mid-level features produced by computer vision algorithms operating on different driver-facing camera views. The proposed TOT model produces continuous estimates of take-over times without delay, and shows promising qualitative and quantitative results in complex real-world scenarios.

  An autonomous driving system should effectively use the information collected from the various sensors in order to form an abstract description of the world. Deep learning models, such as autoencoders, can be used for that purpose, as they can learn compact latent representations from a stream of incoming data. This work proposes CARNet, a Combined dynAmic autoencodeR NETwork architecture that utilizes an autoencoder combined with a recurrent neural network to learn the current latent representation.
