    摘要: An apparatus that controls a DC-DC converter including a switching element of which duty ratio is controlled by the apparatus to regulate the output voltage includes: acquiring device for acquiring the input voltage; converting device for converting the input voltage to a modulated signal representing the input voltage; first limiting section for limiting the duty ratio of the switching element in response to the input voltage represented by the modulated signal; first determining section for determining whether or not the modulated signal is in abnormal condition; and enabling section for enabling the DC-DC converter to continue to convert the input voltage to the output voltage when the determining section determines the abnormal condition. The enabling section includes second limiting section for limiting the duty ratio of the switching element, the second limiting section limits the duty ratio of the switching element when the determining section determines the abnormal condition.

    摘要: An information providing apparatus includes one or more processors; and a memory storing instructions, which when executed by the processors, cause the processors to acquire, by a display unit, information on a predetermined position outside a moving body to display an information providing image for providing information associated with the predetermined position as a virtual image; and control the display unit to change a display position of the information providing image according to movement of the moving body. The display position of the information providing image is changed such that a deviation amount between the predetermined position and a position at which a straight line passing through a reference point within the moving body and the display position of the information providing image reaches a surface on which the moving body is moving decreases as a distance between the moving body and the predetermined position decreases.

    摘要: An information providing apparatus installed in a moving body includes one or more processors, and a memory, the memory storing instructions, which when executed by the one or more processors, cause the one or more processors to display, by a display unit, an information providing image as a virtual image, and control the display unit to change a display position of the information providing image. The information providing image includes a first information providing image and a second information providing image, and the display unit is controlled such that a changing rate of a display position of the first information providing image differs from that of a display position of the second information providing image, and the changing rates of the display positions of the first and the second information providing images both increase as a moving velocity of the moving body increases.

    摘要: An apparatus controls a DC-DC converter that converts an input voltage to an output voltage. The DC-DC converter includes a switching element having a duty ratio controlled by the apparatus to regulate the output voltage, a first transformer, a second transformer and a capacitor. A terminal voltage applied between input and output terminals of the switching element varies depending on the duty ratio and the input voltage. The apparatus may be configured to: limit the duty ratio in response to the input voltage represented by a modulated signal; enable the DC-DC converter to continue to convert the input voltage to the output voltage when an abnormal condition of the modulated signal is determined; and limit the duty ratio of the switching element when the abnormal condition is determined. Main and sub switching elements of the switching element and the capacitor are disposed between the first and second transformers.
