Patent number: 11932118Abstract: The electric vehicle according to the present disclosure calculates motor torque using an MT vehicle model simulating an MT vehicle having a manual transmission and an internal combustion engine. In the first operation mode, an operation amount of a pseudo-clutch pedal and a shift position of a pseudo-gearshift are input to the MT vehicle model to reflect operation of the pseudo-clutch pedal and operation of the pseudo-gearshift in electric motor control. In the second operation mode where the operation of the pseudo-clutch pedal is not needed, an operation amount of a clutch pedal calculated by a driver model is input to the MT vehicle model instead of the operation amount of the pseudo-clutch pedal.Type: GrantFiled: June 16, 2021Date of Patent: March 19, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Akiko Nishimine, Yoichiro Isami, Yoshio Itou, Hiroyuki Amano, Tatsuya Imamura, Hiroaki Ebuchi, Hiroaki Kodera

Patent number: 8384856Abstract: A color filter substrate and a display device are each capable of reducing color separation of a straight line displayed with a mixed color and particularly color separation of a straight white line displayed with a mixed color on a black background. The color filter substrate is a color filter substrate including colored layers of at least four colors, arrayed inside a pixel region, wherein at least one pair of colored layers that are not next to each other when the colored layers of all the colors are arrayed in order of hue is adjacently arranged to each other inside the pixel region.Type: GrantFiled: March 30, 2006Date of Patent: February 26, 2013Assignee: Sharp Kabushiki KaishaInventors: Akiko Itou, Kohzoh Nakamura, Shun Ueki, Tokio Taguchi

Patent number: 8319791Abstract: A display device has a pixel that is defined by a plurality of sub-pixels. The sub-pixels include a red sub-pixel representing red, a green sub-pixel representing green, a blue sub-pixel representing blue and a yellow sub-pixel representing yellow. When the pixel represents white, the luminance of the red sub-pixel is lower than its luminance corresponding to the highest gray scale level. In one embodiment, when the pixel represents white, the luminance of the red sub-pixel is preferably in the range of 25% to 96% of its luminance corresponding to the highest gray scale level. Also, the color temperature of white represented by the pixel is preferably higher than 4200 K, more preferably higher than 5000 K.Type: GrantFiled: June 5, 2006Date of Patent: November 27, 2012Assignee: Sharp Kabushiki KaishaInventors: Shun Ueki, Kozo Nakamura, Tokio Taguchi, Akiko Itou
