Patent number: 11443526Abstract: A road obstacle detection device which uses a pre-learned first identifier to associate a semantic label with each pixel of an image, uses a pre-learned second identifier to estimate a statistical distribution of a semantic label of a predetermined region of interest of the image from a statistical distribution of a semantic label of a peripheral region that surrounds the region of interest, and uses the statistical distribution of the semantic label associated with the region of interest and the statistical distribution of the semantic label estimated for the region of interest to estimate a likelihood that an object is a road obstacle.Type: GrantFiled: August 26, 2020Date of Patent: September 13, 2022Assignee: TOYOTA JIDOSHA KABSHIKI KAISHAInventors: Toshiaki Ohgushi, Kenji Horiguchi, Masao Yamanaka

Patent number: 9163567Abstract: When a computer determines that an accelerator pedal and a brake pedal are simultaneously stepped based on the signals from the accelerator position sensor and a brake switch, the first switch is turned off so that the accelerator sensor signal which will be transmitted into the computer is compulsorily made zero. A throttle-position command value which will be transmitted from the computer into a throttle actuator is reduced to a value corresponding to the idling state. If an engine output is not reduced, the computer turns off a second switch so that a throttle actuator is de-energized. A throttle valve is compulsorily brought into a position corresponding to an idling state by a biasing force of a throttle return spring.Type: GrantFiled: July 11, 2012Date of Patent: October 20, 2015Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABSHIKI KAISHAInventors: Akinori Kouda, Tsutomu Miyazaki

Patent number: 8137865Abstract: A plate member for a fuel cell is provided. The plate member for the fuel cell may be laminated together with a membrane-electrode assembly to constitute a fuel cell having cells and may be provided with a channel forming portion which forms a fluid channel to supply and discharge a fluid to/from the membrane-electrode assembly and/or the cells. The plate member for the fuel cell includes a first covering portion which covers the channel forming portion, and a second covering portion which covers an edge of the first covering portion together with a portion around the edge of the first covering portion.Type: GrantFiled: August 30, 2007Date of Patent: March 20, 2012Assignee: Toyota Jidosha Kabshiki KaishaInventor: Kazutaka Iizuka

Patent number: 7906863Abstract: In a hybrid vehicle of the invention, a hybrid electronic control unit sets a drive point of an engine and torque commands Tm1* and Tm2* of motors MG1 and MG2 in a range of an input limit and an output limit of a battery, in order to satisfy a preset power demand, and sends the engine drive point to an engine ECU and the torque commands Tm1* and Tm2* simultaneously with the input limit and the output limit of the battery to a motor ECU. The motor ECU verifies whether the operations of the motors MG1 and MG2 with the torque commands Tm1* and Tm2* are in the range of the input limit and the output limit of the battery. When the operations of the motors MG1 and MG2 are out of the range of the input limit and the output limit, the motor ECU resets the torque commands Tm1* and Tm2* to make the operations of the motors MG1 and MG2 in the range of the input limit and the output limit and controls the operations of the motors MG1 and MG2 with the reset torque commands Tm1* and Tm2*.Type: GrantFiled: April 22, 2005Date of Patent: March 15, 2011Assignee: Toyota Jidosha Kabshiki KaishaInventor: Hideaki Yaguchi

Publication number: 20050249351Abstract: A computer unit 71 disposed at a vehicle assembly plant 70 sends to an information providing center 40 chassis number information and MAC address information and phone number information of a communication unit 15 of a vehicle. A computer unit 81 at a vehicle sales shop 80 transmits to the center 40 chassis number information and information representing the number plate of the vehicle. The center 40 registers the sent information pieces as movable-body-specifying information and user-specifying information, respectively. By use of an apparatus 10, a user requests the center 40 to provide information. The center 40 authenticates the movable-body-specifying information and the user-specifying information sent from the apparatus 10, checks whether or not the present location of the vehicle coincides with a predetermined location, and specifies the user. Then, the center 40 provides information to the specified user.Type: ApplicationFiled: August 25, 2003Publication date: November 10, 2005Applicant: Toyota Jidosha Kabshiki KaishaInventor: Shunji Miyahara

Patent number: 6041755Abstract: An apparatus for reducing a torque fluctuation of a lean burn combustion engine. An injector supplies fuel to combustion chambers of the engine. An ignitor ignites the fuel supplied into the combustion chambers. A knock sensor detects knocking in the engine. An electronic control unit (ECU) computes a delay amount of the ignition timing based on a result of knock detection by the knock sensor and controls the ignitor to delay the ignition timing by the delay amount to suppress knocking. The ECU also detects torque fluctuation of the engine. The ECU increases an amount of fuel injection from the injector by an increase amount to reduce the torque fluctuation when the detected torque fluctuation is larger than a target value. The ECU limits the increase amount when the ignition timing is delayed by more than a predetermined delay amount.Type: GrantFiled: December 16, 1997Date of Patent: March 28, 2000Assignee: Toyota Jidosha Kabshiki KaishaInventor: Zenichiro Mashiki
