  • Patent number: 11407355
    Abstract: A vehicle headlamp aiming adjustment system includes a headlamp controller configured to adjust an emission direction of light emitted from a headlamp; a sensing unit configured to measure a sensing area on a ground and measure a change of the sensing area; and a controller configured to receive information about the sensing area measured by the sensing unit, compare the measured sensing area with a pre-stored reference area, and transmit a control signal to the headlamp controller such that the emission direction of light is adjusted in accordance with a change of the sensing area when the sensing area is different from the reference area. The above-describe vehicle headlamp aiming adjustment system can check an emission area of light of a headlamp and secure the driver's field of view by correcting the emission area.

  • Publication number: 20220209552
    Abstract: A device for supplying power from a vehicle battery to the outside is provided. The device includes an inverter circuit having a bridge circuit with multiple switching elements and that converts the received DC power into the AC power by switching the switching elements and that outputs the AC power. A controller controls an on/off state of each switching element through pulse width modulation. When an output AC output to the load has a value greater than a preset reference value or an input direct current input into the inverter has a value greater than a preset reference value, the controller changes a duty of each switching element to reduce an output AC voltage output from the inverter. When the reduced output AC voltage has a value equal to or less than a preset reference value, the controller stops a power conversion operation of the inverter.
