Publication number: 20170315771Abstract: Arrangements herein relate to a method and system for selectively displaying surroundings of an autonomous vehicle. The system can include a display to display a plurality of images in which some of the images are images of an environment external to the autonomous vehicle and are images unrelated to the environment external. The system can include cameras to capture the images of the environment external. The system can further include a processor that can be configured to detect a handover event associated with the operation of the vehicle. In response to the detection of the handover event and if the display is displaying images unrelated to the environment external, the processor can also cause the display to display images of the environment external in the place of the images unrelated to the environment external.Type: ApplicationFiled: April 28, 2016Publication date: November 2, 2017Inventor: Norman C.

Patent number: 9555735Abstract: A vehicle cargo box tonneau cover device includes two or more hard panels formed of thin-walled, friction welded polypropylene material hermetically enclosing extruded support beams. Each panel forms an upper surface falling on a common plane when in a deployed position. Adjacent panels are joined along their common edges by a multi-pin hinge disposed entirely below the upper surface to provide a flat overall appearance. The hinge has a first flange carried by a first panel, a second flange carried by an adjacent second panel, and an elongated free-moving link mounted to the first flange for relative rotation about a first axis and mounted to the second flange for relative rotation about a second axis. The two axes are spaced from and parallel to one another, whereby the hinge enables 180° freedom of rotation between the adjacent panels when transitioning between a planer deployed position and a folded retracted position.Type: GrantFiled: January 8, 2015Date of Patent: January 31, 2017Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventor: Norman C.
