Patent number: 12065198Abstract: A working vehicle includes an operator seat and an armrest arranged on a side of the operator seat. The armrest includes an upper surface on which an operation tool arrangement portion is arranged, the operation tool arrangement portion arranging an operation tool, and a side surface having a concave portion. The concave portion is located on an area overlapping, in a front-to-back direction, with another area including the operation tool arrangement portion.Type: GrantFiled: September 14, 2022Date of Patent: August 20, 2024Assignee: KUBOTA CORPORATIONInventors: Takashi Kosaki, Takuya Inamori, Yoshihiko Kuroshita, Michita Kono, Yuji Imanaga

Patent number: 11835131Abstract: A control apparatus for a vehicle provided with (i) a power source, (ii) drive wheels and (iii) a fluid transmission device disposed between the power source and the drive wheels and including a lockup clutch to which a fluid pressure is supplied. A feedback control is executed for correcting a command value of the fluid pressure by a correction amount such that an actual value of a slip amount of the lockup clutch becomes substantially equal to the target value of the slip amount in a slip control. When the actual value has been converged into a given range with respect to the target value, the correction amount is obtained, and the command value for a next execution of the slip control is corrected by learning with use of the obtained correction amount. The given range is set depending on the target value of the slip amount.Type: GrantFiled: January 23, 2023Date of Patent: December 5, 2023Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, Aisin CorporationInventors: Masahide Ichikawa, Kazumitsu Sugano, Shunsuke Yanagi, Yuji Imanaga, Yui Goto, Masatsugu Yoshimoto

Patent number: 7289892Abstract: The present invention provides inspection of a transmission with higher precision and in a shorter period of time. Before a finished A/T is inspected, a V/B ASSY and an ECU are inspected together by a V/B tester in a subsidiary line. A solenoid current command value (a characteristic value inherent in the A/T) for a linear solenoid of the V/B ASSY is corrected and written into the ECU through CAN communication. Spring load of a return spring SP and stroke of the piston of a hydraulic servo for a frictional engagement element are measured. Actually measured values or corrected values of the spring load and the stroke are stored. In the final inspection of the A/T a finished-product tester reads the stored characteristic values and transmits them to the ECU integrated with the A/T through CAN communication. The characteristic values are then written into the ECU. The finished-product tester inspects the finished A/T product, using the characteristic values thus written into the ECU.Type: GrantFiled: December 19, 2003Date of Patent: October 30, 2007Assignees: Aisin AW Co., Ltd., Toyota Jidosha Kabushiki KaishaInventors: Akira Isogai, Masahiko Ando, Naoyuki Fukaya, Takayuki Kubo, Masao Saitou, Yuji Imanaga, Satoshi Yoshida, Masato Matsubara, Norimi Asahara, Katsumi Kono, Tomokazu Inagawa, Hideki Takamatsu
