  • Patent number: 11932118
    Abstract: 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.

  • Patent number: 11926222
    Abstract: An electric vehicle is configured to be able to perform running by an MT mode that controls an electric motor with a torque characteristic like an MT vehicle having a manual transmission and an internal combustion engine, and running by an EV mode that controls the electric motor with a normal torque characteristic. The electric vehicle includes a mode changeover switch for switching to the running by the MT mode.

  • Patent number: 8384856
    Abstract: 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.

  • Patent number: 8319791
    Abstract: 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.

  • Patent number: 7952662
    Abstract: A transflective display device capable of suppressing white balance from shifting to yellow includes filters of R, G, B, and Y, and a region corresponding to a reflective member in the Y filter is covered with a BM. Therefore, filters used in the reflective display are limited to three colors of R, G, and B, and thereby white balance can be prevented from shifting to yellow.
