  • Publication number: 20120291467
    Abstract: A refrigerant cycle device for a vehicle includes a compressor which compresses and discharges refrigerant, a discharge capacity control portion which controls a discharge capacity of the compressor. The refrigerant cycle device further includes a noise determination portion which determines whether an audible noise other than a refrigerant passing noise is in a low noise state, and/or a load determination portion which determines whether an air-conditioning thermal load is in a high load state. The discharge capacity control portion performs a gradual activation control in which the discharge capacity of the compressor is set to be lower than that determined in a normal control, when the noise determination portion determines that the audible noise is in the low noise state, and/or when the load determination portion determines that the air-conditioning thermal load is in the high load state, at an activation time of the compressor.

  • Publication number: 20120274737
    Abstract: Wide-angle imaging data obtained by capturing a view of a vehicle periphery can be converted into wide-angle display data for displaying the view in the same field of view on a display device, and into enlarged display data for enlarging and displaying a portion of the wide-angle imaging data. When the image on the screen of the display is switched between wide-angle display and enlarged display, the target region corresponding to the post-switching display data is set, highlighted, and displayed as the highlighted region (E) on the screen on the pre-switching display data (V1). The surface area of the highlighted region (E) is varied until the surface area highlighted region (E) is the same as the surface area of the target region on the post-switching display data. Lastly, the post-switching display data is displayed in the highlighted region (E).
