    Abstract: An image display device includes a display panel displaying an image, and a diffractive element formed to operate in a 2D mode or a 3D mode so that the image of the display panel is perceived as a 2D image or a 3D image after passing through the diffractive element. In the image display device, the diffractive element includes a first substrate and a second substrate facing each other, a first electrode layer formed on the first substrate that includes a plurality of zones, a second electrode layer formed on the second substrate, and a liquid crystal layer interposed between the first substrate and the second substrate. Further, when the diffractive element operates in the 3D mode, a common voltage is applied to the second electrode layer, and polarity of voltages applied to the first electrode layer with respect to the common voltage is inverted every zone.

  • Clutch Torque Trajectory Correction to Provide Torque Hole Filling during a Ratio Upshift
    Publication number: 20160114803
    Abstract: A control system and method for controlling a multiple gear ratio automatic transmission in a powertrain for an automatic transmission having pressure activated friction torque elements to effect gear ratio upshifts. The friction torque elements are synchronously engaged and released during a torque phase of an upshift event as torque from a torque source is increased while allowing the off-going friction elements to slip, followed by an inertia phase during which torque from a torque source is modulated. A perceptible transmission output torque reduction during an upshift is avoided. Measured torque values are used during a torque phase of the upshift to correct an estimated oncoming friction element target torque so that transient torque disturbances at an oncoming clutch are avoided and torque transients at the output shaft are reduced.

    Patent number: 9316198
    Abstract: Methods and systems are provided for pressurizing a transmission hydraulic circuit including a transmission mechanical pump coupled to an engine though a gearbox. One example method comprises, during an engine start, adjusting a speed ratio between the transmission pump and the engine between a first speed ratio and a second speed ratio, the pump rotating faster relative to the engine at the first speed ratio as compared with the second speed ratio. In this way, the pump may be driven at different speed ratios relative to the engine to provide better pressurization in the transmission.

  • CLUTCH TORQUE TRAJECTORY CORRECTION TO PROVIDE TORQUE HOLE FILLING DURING A RATIO UPSHIFT
    Publication number: 20160017996
    Abstract: A multiple ratio transmission having an input shaft, an output shaft and oncoming clutch and off-going clutch for effecting ratio upshifts is provided. The transmission also includes a transmission controller configured for controlling shifts. During the torque phase of a ratio upshift, the controller increases input torque. Next, the controller estimates an oncoming clutch target torque. The controller controls a torque input to ensure the off-going clutch remains locked. The controller measures an actual transmission value for a torque transmitting element of the transmission and corrects the oncoming clutch target torque using the actual transmission value whereby an increasing torque for the oncoming friction element is achieved with minimal torque transients along the output shaft during the upshift.
