Publication number: 20100005412Abstract: An in-vehicle display apparatus includes (i) an operation device having an operation knob, and (ii) a display control device having a display section. The operation device has a drive section which gives force to the operation knob. When the display section displays a display window to enable a scroll display in which several selection buttons are circulated, the display control device acquires a reactive force map. The map specifies that a vibration is applied to the operation knob when the cursor is located on the selection button at the tail end of the series of the selection buttons in the display window. The display control device then instructs the drive section to apply the vibration to the operation knob based on the acquired reactive force map.Type: ApplicationFiled: June 30, 2009Publication date: January 7, 2010Applicant: DENSO CORPORATIONInventors: Makiko Tauchi, Takeshi Yamamoto, Nozomi Kitagawa

Publication number: 20090307588Abstract: An apparatus for controlling operation of an operation device controls the operation device in the following manner. That is, when a pointer on a display screen is controlled by the operation device, the operation of the operation device is regarded as an equivalent of a press operation of an OK button that affirms a certain decision, or as an equivalent of a press operation of a switch button that switches a current screen to the next one, upon detecting an exit of the pointer from a wall area of the screen.Type: ApplicationFiled: May 29, 2009Publication date: December 10, 2009Applicant: DENSO CORPORATIONInventors: Makiko Tauchi, Asako Nagata, Nozomi Kitagawa, Takeshi Yamamoto, Takeshi Haruyama

Publication number: 20090284467Abstract: An input device having a manipulation member is disclosed. The input device has an absolute input mode and a relative input. In the absolute input mode, the input device determines a coordinate of a pointed point on a window of a display unit based on a coordinate of the manipulation member. In the relative input mode, the input device determines the pointed point on the window in a relative manner based on a two-dimensional displacement of the manipulation member with respect to a reference position, which is set when an input mode is switched into the relative input mode. When the manipulation member receives a load that causes the manipulation member to move beyond a predetermined range, the input device generates and applies a force corresponding to the load to the manipulation member.Type: ApplicationFiled: May 14, 2009Publication date: November 19, 2009Applicant: DENSO CORPORATIONInventors: Masahiro Itoh, Nozomi Kitagawa, Shigeaki Nishihashi, Takeshi Yamamoto, Takeshi Haruyama

Patent number: 7535457Abstract: In a force-feedback input device, when the cursor moves on a line parallel to a line between a center of a first button and a center of a second button, an area is determined between a first position, which corresponds to the center of the first button, and a second position, which corresponds to the center of the second button, such that the area extends a distance W on both sides of a mid-point between the first and second positions. In this area, the first and second external-force generation portions are controlled so that a scalar value |F| of an attractive force exerted on an operating portion is decreased according to the equation |F|=d/W·|F| as the cursor moves closer to the mid-point, where d is a distance between the cursor and the mid-point.Type: GrantFiled: November 8, 2004Date of Patent: May 19, 2009Assignee: Alps Electric Co., Ltd.Inventors: Ken Matsumoto, Yuji Ito, Nozomi Kitagawa, Takeshi Haruyama, Hiroaki Sasaki

Publication number: 20090076676Abstract: An input apparatus for a vehicle, the apparatus being used for operation input to various vehicular electronic devices, sets position input permission areas on a two-dimensional operation surface of an operation input device discretely by control of a main controller. In control modes of a reaction force, a guide input mode where position indication operations to the areas on the operation surface by the operation input device are guided along unique paths defined in the respective area and an arbitrary mode where the position indication operations are not guided but performed freely can be changed. The guide input mode is set at least during a vehicle travel.Type: ApplicationFiled: August 21, 2008Publication date: March 19, 2009Applicants: DENSO CORPORATION, KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventors: Norio YAMAMOTO, Nozomi Kitagawa, Katsuhide Kumagai, Masahiko Miyata

Publication number: 20080238874Abstract: A display device is provided in a central position of an instrument panel in a vehicle compartment, and an operation device is provided in a center console. The operation device is formed with a case body having a palm rest, with is provided with a pointing device and four finalizing switches. A menu display window showing an array of multiple function selection items or a list display screen is displayed on a screen of the display device. The user selects a desired function selection item by moving a cursor by operation of an operation knob of the pointing device. In this state, the user ON operates any one of the finalizing switches, thereby performing finalize-designation. A user can thus operate the operation device from any one of multiple directions without uncomfortable feeling.Type: ApplicationFiled: March 26, 2008Publication date: October 2, 2008Applicants: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Norio Yamamoto, Nozomi Kitagawa, Hiroaki Sasaki, Takeshi Haruyama, Motohiro Fukumoto, Hirotake Sano, Haruyuki Kodera, Kenji Mori, Kazuhiro Kawachi

Patent number: 4704999Abstract: In a fuel injection control for diesel engine, in order to eliminate engine noise, particularly, the "idling knocking" noise occurring during engine idling, by controlling a pilot injection, a method for controlling the fuel injection includes the steps of: detecting an idling state of the diesel engine, pressure in a combustion chamber, engine rotational speed and crank angle to obtain a reference position; selecting a valve opening pressure of a fuel injection nozzle at a relatively low level when the idling state is detected, thereby setting a two peaks characteristic of a fuel injection rate within an extent of the idling rotational speed; and controlling a pressure increment rate in the combustion chamber to within a predetermined value by changing a fuel injection quantity of a pilot injection.Type: GrantFiled: June 3, 1986Date of Patent: November 10, 1987Assignee: Nippon Soken, Inc.Inventors: Atsushi Hashikawa, Nozomi Kitagawa, Tetsuro Kikuchi
