Patent number: 10650562Abstract: A display control device that displays an image includes an acquirer, a drawer, and an image combiner. The acquirer acquires layer information which defines (i) individual layers corresponding to display regions of a plurality of display devices and (ii) a common layer including the display regions of the plurality of display devices, as layers of images each constituted by a plurality of layers. The drawer draws first combination images to be displayed so as to move among the plurality of display devices in the common layer, and draws second combination images to be independently displayed by the display devices in the individual layers, based on the layer information acquired by the acquirer. The image combiner combines the first combination images drawn in the common layer by the drawer with the second combination images of the corresponding individual layers. Accordingly, it is possible to reduce a processing load when image display is linked between a plurality of displays.Type: GrantFiled: March 20, 2018Date of Patent: May 12, 2020Assignee: DENSO TEN LIMITEDInventors: Takashi Eguchi, Hirokazu Ichihara, Daitaro Yamasaki

Patent number: 9958062Abstract: A CVTECU includes a secondary-pressure control section and a line-pressure control section that performs a same-pressure control to equalize a line pressure and a secondary pressure with each other if a predetermined start condition is satisfied. The line-pressure control section realizes a same-pressure state between the line pressure and the secondary pressure by lowering the line pressure below a target secondary pressure, and then controls the line pressure such that an actual secondary pressure is brought to the target secondary pressure by hydraulic feedback control while maintaining the same-pressure state. The secondary-pressure control section includes a restriction section that restricts an accumulation of integral term of an integral action for a duration between a time point at which the actual secondary pressure starts to be pushed down and a time point at which the same-pressure state between the line pressure and the secondary pressure is realized.Type: GrantFiled: February 26, 2015Date of Patent: May 1, 2018Assignee: JATCO LtdInventors: Tomoaki Honma, Seiichiro Takahashi, Takahiro Kobayashi, Takashi Eguchi, Hisao Nobu, Kenji Sakakibara

Patent number: 9945478Abstract: A control apparatus for a continuously variable transmission with a sub transmission includes a primary solenoid valve installed at an oil passage in a midway position between a mechanical oil pump and a primary pulley and configured to control a hydraulic pressure to be supplied to the primary pulley. The control apparatus further includes a transmission controller which outputs a primary current command value to a primary solenoid valve. The transmission controller outputs the primary current command value which previously closed the oil passage between the mechanical oil pump and the primary pulley to the primary solenoid valve before a rise in an engine revolution number due to at least a re-start of the engine, when a coast stop control/an idle stop control is carried out.Type: GrantFiled: December 10, 2014Date of Patent: April 17, 2018Assignee: JATCO LtdInventors: Yoshinobu Kawamoto, Tomohiro Utagawa, Takashi Eguchi

Patent number: 9562546Abstract: In a hydraulic control circuit including a solenoid valve, whose change responsiveness in an actual pressure with respect to a change in an instructional pressure deteriorates when the instructional pressure enters a dead band region on a lower pressure side than a dead band threshold, for adjusting a hydraulic pressure supplied to a hydraulic device operated by the hydraulic pressure based on the instructional pressure, the instructional pressure is increased in a stepwise manner to a charge pressure higher than the dead band threshold, when the instructional pressure is set in the dead band region and the instructional pressure increases within the dead band region to such an extent that a speed ratio does not change. Then, a lower limit of the instructional pressure is set to the dead band threshold, and use of the dead band region is prohibited for a certain period of time.Type: GrantFiled: February 21, 2013Date of Patent: February 7, 2017Assignee: JATCO LTDInventors: Seiichiro Takahashi, Takashi Eguchi, Tomohiro Utagawa, Hisao Nobu, Kenji Sakakibara, Takahiro Ikeda, Masayuki Shimizu
