Patent number: 9389616Abstract: Provided is a driving force control device for a four-wheel-drive vehicle that can evade an occurrence of excessive understeer and oversteer in situations unintended by the driver, by appropriately controlling driving forces to be distributed to sub-drive wheels. The driving force distribution device of the four-wheeled vehicle controls driving force to be distributed to the rear wheels (Wr, Wr) by the clutch (10) for front-and-rear torque distribution so that the wheels (Wf, Wf) are main drive wheels and the rear wheels (Wr, Wr) are sub-drive wheels. The driving force distribution device is adapted to perform control to restrict the upper limit of the four-wheel drive torque based upon an estimated driving force and steering angle of the vehicle, when calculating four-wheel drive torque to be distributed to the rear wheels (Wr, Wr) by the driving force distribution device (10).Type: GrantFiled: June 12, 2012Date of Patent: July 12, 2016Assignee: HONDA MOTOR CO., LTD.Inventors: Ryuichi Murakami, Jiro Hara, Nor Hairuddin, Yusuke Sakaguchi, Naoharu Takatani

Publication number: 20150036677Abstract: There is a need to enable decompression of a speech signal even if no network synchronizing signal is output from a baseband processing portion. For this purpose, an information processing device includes a first serial interface. The first serial interface includes a notification signal generation circuit that generates a notification signal each time compressed data incorporated from the baseband processing portion reaches a predetermined data quantity, and notifies a speech processing portion of this state using the notification signal. The speech processing portion includes a synchronizing signal generation circuit that generates a network synchronizing signal based on the notification signal. A clock signal for PCM communication is generated based on the network synchronizing signal. A speech signal can be decompressed even if no network synchronizing signal is output from the baseband processing portion.Type: ApplicationFiled: October 17, 2014Publication date: February 5, 2015Inventors: Yutaka UCHIMURA, Takahiro IRITA, Jiro HARA

Patent number: 8505669Abstract: In the case where a difference between rotational speeds of right and left wheels detected by wheel speed sensors is less than a predetermined value, a right and left wheel power transmission control section distributes driving force between the right and left wheels so that a total value of the driving force of the right and left wheels does not exceed a limit value set up by a front and rear wheels power transmission control section. In the case where the difference between the rotational speeds of the right and left wheels is the predetermined value or more, the right and left wheel power transmission control section transmits the driving force up to a driving force upper limit for each wheel to the respective right and left rear wheels regardless of the total value of the driving force of the right and left rear wheels.Type: GrantFiled: March 25, 2010Date of Patent: August 13, 2013Assignee: Honda Motor Co., LtdInventors: Masahide Ueda, Jiro Hara
