Publication number: 20220284543Abstract: A pixel is appropriately interpolated regarding a histogram image in which a distance histogram is allocated to each pixel position. A signal processing apparatus according to the present technology includes a histogram generation unit that inputs a histogram image in which a distance histogram indicating results of a plurality of times of distance measurement as frequency information for each distance is allocated to each pixel position and generates a distance histogram of an interpolation target position in the histogram image on the basis of distance histograms of a plurality of pixel positions near the interpolation target position.Type: ApplicationFiled: June 7, 2020Publication date: September 8, 2022Inventors: KENSEI JO, TOMOHIRO MATSUKAWA, MITSUHARU OHKI, MASAHIRO WATANABE, KENICHI TAYU, KEITAROU AMAGAWA, KUMIKO MAHARA, TAKAHISA UENO

Patent number: 10460185Abstract: A system and method for roadside image tracing are described herein. The system includes a camera mounted on a vehicle configured to capture images of objects around the vehicle while driving along a route of a plurality of routes, and processing circuitry. The processing circuitry is configured to receive the captured images from the camera and vehicle parameters including speed, a fuel level, and a mileage, extract objects and locations of the objects within the captured images including information related to driving, determine a route ranking based on the information collected from the objects during one or more trips along each route of the plurality of routes, generate route options based on the route ranking and the vehicle parameters, and transmit route options to a display.Type: GrantFiled: January 30, 2018Date of Patent: October 29, 2019Assignee: TOYOTA MOTOR ENGINEERING & MANUFACTURING NORTH AMERICA, INC.Inventors: Jonathan C. Hall, Tomohiro Matsukawa

Patent number: 10303339Abstract: A vehicular human-machine interface, an instrument cluster and a method of providing information to a driver of a vehicle. The interface includes a multi-information display that provides a driver numerous dynamically-adjustable icons that are representative of a vehicle systems such that the driver can view, and if necessary, control through the interface. During use by a driver to navigate among the various icons being displayed, the human-machine interface enhances a driver's visual acuity by providing notorious indicia of the status of a particular vehicle system that may be of interest to the driver. In addition, by having certain information be arranged in a dynamic presentation format for selective viewing rather than arranged statically, certain information not of immediate interest can be temporarily removed, thereby freeing up the display to show a larger number of the icons on any particular screen being viewed.Type: GrantFiled: August 26, 2016Date of Patent: May 28, 2019Assignee: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Talia T. Ho, Earnee J. Gilling, Tomohiro Matsukawa

Publication number: 20180074687Abstract: A vehicular human-machine interface, a dashboard and a method of providing information to a driver of a vehicle. The interface includes a multi-information display that provides a driver icons that are representative of a vehicle systems such that the driver can view, and if necessary, control through the interface. Input is simplified through a reduced set of directional buttons on a steering wheel-mounted four-way switch. By eliminating a separate BACK button from the steering wheel, driver input operations to achieve navigational control between various vehicle system menus that correspond to the icons, as well as sub-menus within a particular vehicle system, is simplified. The simplified navigation that is either between various icons on the display or various menu-based levels that can be sequentially shown also permits, in addition to viewing various vehicle system operational parameters, the ability to change such parameters through adjustment through the human-machine interface.Type: ApplicationFiled: September 14, 2016Publication date: March 15, 2018Applicant: Toyota Motor Engineering & Manufacturing North America, Inc.Inventors: Talia T. Ho, Earnee J. Gilling, Tomohiro Matsukawa

Publication number: 20170206045Abstract: A first-screen is continuously displayed on a display according to contents of the first-screen, in a case where a first display request is cancelled before a continuous display time in which the first-screen based on the first display request has been continuously displayed on the display, reaches a predetermined reference time. Meanwhile, after display of the first-screen has been continued and before the continuous display time of the first-screen reaches the reference time, in a case where a second display request making an instruction for displaying a second-screen to be displayed at a highest priority occurs, the display is switched from the first-screen to the second-screen at a time when the second display request occurs, and, in a case where the second display request does not occur, the first-screen is displayed on the display until the continuous display time of the first-screen reaches the reference time.Type: ApplicationFiled: November 16, 2016Publication date: July 20, 2017Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tomohiro MATSUKAWA, Toshinori AOKI
