  • Alignment method and system for radar of vehicle
    Patent number: 9523769
    Abstract: A vertical alignment method for a radar of a vehicle includes the steps of radiating radio wave to a forward ground by a radar which is installed on the vehicle; receiving reflected wave which is reflected from the ground; and determining whether or not a vertical misalignment of the radar occurs, based on the reflected wave.

  • HEADLAMP CONTROL DEVICE FOR VEHICLE
    Publication number: 20100123395
    Abstract: A headlamp control device for a vehicle is provided. The device includes a front sensor, a wheel speed sensor, an Electrical Control Unit (ECU), a first ballaster, a second ballaster, a relay switch, and a power supply switch. The front sensor senses a target vehicle. The wheel speed sensor detects a speed of a reference vehicle. The ECU outputs a switching control signal. The first ballaster generates a first boosting voltage. The second ballaster generates a second boosting voltage. The relay switch supplies an internal voltage to first and second high-beam lamps, or first and second ballasters. The power supply switch turns on in response to a switching control signal.
