    摘要: When instructed to switch control modes between overmodulation PWM control and sinusoidal wave PWM control, control device corrects the amplitude of a voltage command signal based on a state of power conversion operation performed by an inverter, so as to suppress a change in an influence of dead time over a voltage applied to an alternating-current motor upon switching the control modes. The state of the power conversion operation performed by the inverter includes at least one of a present value of a carrier frequency in a control mode currently employed, an estimated value of the carrier frequency to be obtained when switching the control modes, the length of the dead time, a power factor of alternating-current power exchanged between the inverter and the alternating-current motor, and a driving state of the alternating-current motor.

    摘要: The present invention provides an in-vehicle display apparatus including a switching button 151 that switches between a single display mode displaying the same images on the basis of a single image source on first and second screens, and a dual display mode displaying D-seat and P-seat images on the basis of different image sources or the same image source on the first and second screens, respectively. Therefore, according to user's request, it is possible to switch between a case where the same images are displayed on the first and second screens, and a case where the different images are displayed on the first and second screens, respectively.

    摘要: A display device includes a display section and a video signal generating section. The display section displays n video pictures in n viewing directions on one and the same screen on a basis of a video signal where n indicates natural number. First particular number of pixels are arranged in a first direction in the display section. The video signal generating section arranges pixels of each of n video source signals at predetermined intervals in a first direction to generate the video signal. Each of the n video source signal indicates a video picture in which second particular number of pixels are arranged in the first direction. The second particular number is less than the first particular number.
