Publication number: 20190227635Abstract: Vehicle systems and methods for determining a final target position based on either a first target position and a second target position are disclosed. A vehicle includes a user detection system configured to output a gesture signal in response to a hand of a user performing at least one gesture to indicate a final target position. The vehicle also includes a user gaze monitoring system configured to output an eye location signal that indicates an actual eye position of the user. The vehicle also includes one or more processors and one or more non-transitory memory modules communicatively coupled to the processors. The processors store machine-readable instructions that, when executed, cause the one or more processors to select either the first target position or the second target position as the final target position based on a first accuracy and a second accuracy.Type: ApplicationFiled: January 23, 2018Publication date: July 25, 2019Applicant: Toyota Research Institute, Inc.Inventors: Masaaki Yamaoka, Yuki Horiuchi

Patent number: 9671782Abstract: There is provided an autonomous driving device that improves the convenience for a driver in the switching between autonomous driving and manual driving. When the driver discovers an obstacle which cannot be detected by an autonomous driving device, and performs a driving operation which causes a manual driving switching threshold value to be exceeded for an operation time less than or equal to an operation threshold value so as to avoid the obstacle, a control unit of the autonomous driving device switches autonomous driving to manual driving, and then the control unit switches manual driving to autonomous driving even if the driver does not perform an autonomous driving switching operation. For this reason, it is possible to improve the convenience for the driver in the switching between autonomous driving and manual driving.Type: GrantFiled: October 8, 2015Date of Patent: June 6, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masaaki Yamaoka, Kohshi Katoh, Eishi Takeuchi, Tomoyuki Kuriyama, Hikaru Sato

Publication number: 20160304126Abstract: By a display unit of a vehicle control device, a lane line which partitions a driving lane and a neighboring lane is displayed on a display screen in a perspective from a host vehicle to the front of the host vehicle and the lane line is displayed while the position of the lane line is changed according to a progress situation of a lane change. For this reason, a movement of the lane line in a display of the display screen and a movement of the lane line at the point of view of a driver of the host vehicle become more similar. Therefore, the driver of the host vehicle has a reduced uncomfortable feeling with the display of the display screen, and thus it becomes easier for the driver of the host vehicle to grasp the progress situation of the lane change.Type: ApplicationFiled: April 7, 2016Publication date: October 20, 2016Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masaaki YAMAOKA, Yosuke WADA
