  • Patent number: 10266109
    Abstract: When a duration time period in which a turn signal lever is held at a first operation position P1L (P1R) is equal to or larger than an assist request confirmation time period, a driving support ECU starts a lane change assist control. When an operation force is released under a situation in which the turn signal lever positions at the first operation position, the turn signal lever returns to a neutral position PN. When the driving support ECU starts the lane change assist control, the driving support ECU continues flashing a turn signal until a turn signal turning-off condition depending on a state of the lane change assist control is established. When the turn signal lever is performed at a second operation position P2L (P2R) while the lane change assist control is being executed, the lane change assist control is stopped.

When the forward vehicle exists, the headlight system can prevent the lamp unit from emitting a glare type light to the forward vehicle. Thus, the disclosed subject matter can provide vehicle headlight systems, which can emit favorable light patterns toward a pedestrian as a marking light, and which can provide favorable light distribution patterns to drive at night.

    Abstract: A vehicular lighting adjustment system (10) has a housing (12) with at least two headlamp adjusters (14), each headlamp adjuster (14) comprising a rocker arm (16) pivotally mounted about a pivot axis (X). A common adjuster (30) is mounted to the housing (12) for rotational displacement. Respective elevation tuning adjusters (34) bear on rocker arms (16) and are displaceable along the common adjuster (30) from an initial axial position to an adjusted axial position whereby each rocker arm (16) deflects about its pivot axis (X). The elevation tuning adjusters (34) are selectively fixed to the adjustment rod (30) in the adjusted axial position. After each elevation tuning adjuster (34) is fixed in its adjusted axial position to the common adjuster (30), displacement of the common adjuster (30) simultaneously displaces the headlamp adjusters (14) by pivotal motion of the rocker arms (16) about their respective said pivot axes (X).

  • Publication number: 20150146441
    Abstract: A vehicle lamp control apparatus includes a receiver, a storage, a correction section, and an adjustment instruction section. The receiver receives output values of an acceleration sensor. The storage stores information indicating an ideal positional relationship between sensor-side axes and vehicle-side axes. The correction section plots the output values, obtained during running of a vehicle, on coordinates in which acceleration in a vehicle longitudinal direction is set to a first axis and acceleration in a vehicle lateral/vertical direction is set to a second axis, derives a straight line from plotted points, calculates displacements of the sensor-side and vehicle-side axes from the ideal positional relationship, using an inclination of the straight line, and corrects the information. The adjustment instruction section derives a tilt angle of the vehicle from current acceleration using the corrected information, and generates a control signal to instruct adjustment of an optical axis of a vehicle lamp.
