Patent number: 6556134Abstract: In display apparatus and method for an automotive vehicle, a display (2) is disposed on a position of the vehicle placed in a proximity to a dashboard surface of the vehicle and a controller (7), when a state of the vehicle which satisfies a predetermined condition is detected, executes a process to gradually reduce a brightness of an image screen of the display toward a predetermined direction which is more distant from a direction of a line of sight of a vehicular driver when the vehicular driver gazes a vehicular forward direction. In one embodiment, the controller gradually reduces the brightness of the image screen of the display toward the predetermined direction in a linear manner. The predetermined direction is, for example, directed from an upper end of the image screen to a lower end thereof.Type: GrantFiled: November 14, 2001Date of Patent: April 29, 2003Assignee: Nissan Motor Co., Ltd.Inventors: Yoshiharu Nakaji, Satoshi Kitazaki, Kazuhito Kato, Shunsuke Hijikata, Akinari Hirao

Patent number: 5416844Abstract: An apparatus for reducing periodical noises transmitted from a noise source into a vehicle passenger compartment. The apparatus comprises control sound sources for producing control sounds in the vehicle passenger compartment, residual noise sensors for detecting the residual noises in the vehicle passenger compartment, transfer function filters modeled on transfer function between the control sound sources and the residual noise sensors, and adaptive digital filters having variable filter coefficients. A reference signal is produced in the form of a series of impulses having the same period as the noises. The transfer function filters are convoluted with the reference signal to produce reference processed signals. The adaptive digital filters are convoluted with the reference signal to generate drive signals to drive the control sound sources.Type: GrantFiled: March 3, 1993Date of Patent: May 16, 1995Assignee: Nissan Motor Co., Ltd.Inventors: Yoshiharu Nakaji, Izuho Hirano, Kazuhiro Doi, Tsutomu Hamabe, Kenichiro Muraoka, Koji Yamada

Patent number: 5236182Abstract: In order to attenuate vibration which tends to be transmitted from a power unit to a vehicle passenger during the idling mode of engine operation, ERF filled engine mounts are arranged so that when neither of two orifice passages are restricted by impressing a voltage on ERF viscosity control electrodes included therein, the frequency at which the dynamic spring constant exhibits a minimum value is the same as the frequency at which the vibration transmission phase maximizes while one of the two orifice passages is restricted by the application of a voltage on the set of electrodes disposed therein. Rapid cyclic control of the dynamic spring constant and the vibration transmission phase for each mount used to support a power unit is carried out. This enables a desirable compromise in the control of the two different parameters.Type: GrantFiled: November 27, 1991Date of Patent: August 17, 1993Assignee: Nissan Motor Co., Inc.Inventors: Hirofumi Aoki, Yoshiharu Nakaji, Kazuhiro Doi, Shigeki Sato

Patent number: 5226500Abstract: A vibration sensor is disposed at an evaluation point on the vehicle floor proximate the driver's seat. This sensor, in combination with one disposed on a electrically controllable engine mount, is used to determine the magnitude and orientation of a vector of vibration which reaches the evaluation point and which combines with other vibrational vectors in a manner which results in the generation of vibration at the evaluation point. A mount control signal is controlled in a manner which modifies the vibration vector and attenuates the vibration at the evaluation point.Type: GrantFiled: November 9, 1992Date of Patent: July 13, 1993Assignee: Nissan Motor Co., Ltd.Inventors: Kazuhiro Doi, Hirofumi Aoki, Shigeki Sato, Yoshiharu Nakaji, Tsutomu Hamabe

Patent number: 5111507Abstract: A system for lowering noise level in a vehicular cabin produces an acoustic vibration canceling noise creative vibration induced in synchronism with an engine revolution. The system generates a rectangular wave signal having 50% duty cycle. The system includes means for producing a periodic signal having an interval half of a period of the noise created by vibration. The signal level of the rectangular signal is switched between HIGH and LOW levels alternatively at the time of occurrence of the periodic signal.Type: GrantFiled: July 24, 1990Date of Patent: May 5, 1992Assignee: Nissan Motor Company, LimitedInventor: Yoshiharu Nakaji
