  • Patent number: 10197405
    Abstract: A route guidance system, a route guidance method, and a computer program are provided that enable a user to understand in advance a section where automated driving control is interrupted. The route guidance system is configured to: when a recommended route from a departure point to a destination including an automated driving section where automated driving control of a vehicle is performed is searched for, acquire candidate routes that are candidates for the recommended route; specify, for each of the candidate routes, an interruption section where the automated driving control is interrupted in the automated driving section included in the candidate route; and provide guidance, for each of the candidate routes, in a manner distinguishing a section that corresponds to the interruption section from a section that does not correspond thereto in the automated driving section included in the candidate route.

  • Publication number: 20180120844
    Abstract: Autonomous driving assistance systems, methods, and programs determine if an execution restricted section is located ahead in a vehicle travel direction during autonomous driving assistance. If so, the systems, methods, and programs obtain required preliminary operation time that is based on a type of the execution restricted section. The systems, methods, and programs determine based on a vehicle speed and the required preliminary operation time, if time required to reach a start point of the execution restricted section is equal to or less than the required preliminary operation time. If so, the systems, methods, and programs determine if a vehicle state satisfies an executable condition under which autonomous driving assistance can be continued in the execution restricted section. If not, the systems, methods, and programs control the vehicle or prompt a user to shift the state of the vehicle to a state that satisfies the executable condition.

  • Publication number: 20130187875
    Abstract: An operation input system and method are provided: The system includes a touch pad that includes an operation plate having an operation surface. A plurality of protrusion members arranged in accordance with a predetermined rule along the operation surface. A display device provided separately from the touch pad, wherein in the case where the display screen is divided into a plurality of screen regions that display independent images, a protrusion control section divides the operation surface into a plurality of operation surface regions corresponding to respective ones of the plurality of screen regions, the number of the operation surface regions being the same as the number of the screen regions, sets a boundary between the operation surface regions such that an area of each of the operation surface regions corresponds to a display content of the corresponding screen region, and causes the protrusion members to be protruded along the boundary.

  • Publication number: 20130162563
    Abstract: An operation input device and method are provided. The operation input device includes a touch pad having an operation plate on a surface of which an operation surface is formed. The operation plate is configured to sense an object in contact with or in proximity to the operation surface to receive input corresponding to a position of the sensed object. The device also includes a protrusion member that can penetrate through the operation plate to protrude from the operation surface and a protrusion control section that controls a position of the protrusion member. The operation input device also includes a display device that displays an image on the display screen and a depiction control section that controls depiction of the image to be displayed on the display screen, wherein the protrusion control section correlates coordinates of the display screen and coordinates of the operation surface with each other.

  • Publication number: 20130162559
    Abstract: An input system and method are provided. The input system includes a display device having a display screen and an input detection device that has an operation surface provided at a distance from the display device and that is configured to detect an operation performed on the operation surface. The input system also includes an elevation formation device configured to form an elevated portion on the operation surface. As control device is also include, the control device is configured to control a display content to be displayed on the display screen, decide a position of the elevated portion on the operation surface in accordance with the display content, and control the elevation formation device so as to form the elevated portion at the decided position.
