Methods and systems for leveling a headlamp of a vehicle on a ground surface using a portable device may include determining, by a processor and a leveling software application tool of the portable device, a zero reference earth plane of the ground surface on which the vehicle is disposed, setting the zero reference earth plane as a vehicle longitudinal axis of the vehicle with respect to the ground surface, determining a current illumination axis of the headlamp based on a feedback from the headlamp received by the portable device, and generating a calibration level angle based on a comparison of the vehicle longitudinal axis and the current illumination axis.

A leveling apparatus for a vehicle headlamp includes: a housing disposed at a front side of a vehicle; a light source module disposed in the housing to emit light; a tilting sensor disposed in the housing to detect an inclination degree of a road; a tilting means to tilt the light source module and the tilting sensor together; and a controller. The controller receives a signal detected by the tilting sensor and controls the tilting means based on the inclination degree of the road to adjust a light emission angle of the light source module. In addition, the tilting sensor operates until a sensed output of the tilting sensor reaches a normal range.

An environmental sensor system in a two-wheeled vehicle is capable of being coupled to the two-wheeled vehicle via a carrier unit, the carrier unit being realized so as to be pivotable about an axis of the two-wheeled vehicle and, when there is a deflection of the two-wheeled vehicle, being pivoted about the two-wheeled vehicle axis in a direction opposite to the deflection.

The controller includes a receiver configured to receive an acceleration information detected by the acceleration sensor, a control unit configured to derive a vehicle longitudinal direction acceleration and a vehicle vertical direction acceleration from the acceleration information, and to generate a control signal for instructing an adjustment of an optical axis of the vehicle lamp, based on a variation in a ratio between a temporal change amount of the vehicle longitudinal direction acceleration and a temporal change amount of the vehicle vertical direction acceleration during at least one of an acceleration and a deceleration of a vehicle, and a transmitter configured to transmit the control signal to an optical axis adjusting portion of the vehicle lamp.

A vehicular multi-sensor system includes a plurality of sensors that include at least a forward-viewing camera and a forward-sensing 3D point-cloud LIDAR sensor.

Image data captured by the forward-viewing camera is transferred to and is processed at an electronic control unit (ECU). 3D point-cloud LIDAR data captured by the forward-sensing 3D point-cloud LIDAR sensor is transferred to and processed at the ECU. Responsive at least in part to processing at the ECU of 3D point-cloud LIDAR data captured by the forward-sensing 3D point-cloud LIDAR sensor, a traffic participant present forward of the equipped vehicle is detected.

An optical axis control apparatus is provided with a relative-road-surface-angle calculating unit which calculates a relative horizontal plane angle being an inclination angle of a vehicle with respect to a horizontal plane by using an output value of an acceleration sensor provided on the vehicle and calculates a relative road surface angle being an inclination angle of the vehicle with respect to a road surface by integrating an amount of change of the relative horizontal plane angle while the vehicle is stationary, a relative-road-surface-angle correcting unit which obtains braking information indicating an operation state of a brake device provided on the vehicle and corrects the relative road surface angle for a change in the braking information, and an optical axis control unit which controls an optical axis of headlights provided on the vehicle using the relative road surface angle corrected by the relative-road-surface-angle correcting unit.

Provided is a lighting control device capable of reducing the lighting delay when a light source is turned on/off in accordance with the bank angle of a vehicle. The lighting control device which controls the lighting state of the light source sets the time period required for turning on the light source to be shorter as the vehicle speed is higher when the inclination angle of a vehicle body in the vehicle width direction is larger than a reference value, and causes the light source to be fully turned on over the set time period. The lighting control device also sets the time period required for turning off the light source to be shorter as the vehicle speed is higher when the inclination angle of a vehicle body is smaller than a reference value, and causes the light source to be dimmed and turned off over the set time period.

A lighting system for a vehicle at least one primary low beam element at least a first adaptive element, a second adaptive element and a third adaptive element and a lean angle sensor generating a lean angle signal. A controller controls the plurality of adaptive elements so that the first element, the second element and third element are extinguished at less than a first lean angle, between the first and a second lean angle greater than the first lean angle illuminating the first adaptive element, between the second and a third lean angle greater than the second lean angle illuminating the first and second adaptive elements, between the third lean angle and a fourth lean angle greater than the third lean angle illuminating the second adaptive element and the third adaptive element and extinguishing the first adaptive element in response to the lean angle signal.

An optical axis control apparatus includes an optical axis controlling unit for calculating a pitch angle using output values from an acceleration sensor provided in a vehicle and controlling, using the pitch angle, optical axis angles of headlights provided in the vehicle, during stop of the vehicle; and a rolling motion determination unit for determining, when the vehicle has started traveling, whether there has been a rolling motion during the stop of the vehicle. When the pitch angle has been changed during the stop of the vehicle due to loading or unloading of baggage or a change of passengers, etc., and the rolling motion determination unit determines that the rolling motion exists, the optical axis controlling unit corrects, when the vehicle has started traveling and the rolling motion has been terminated, the changed pitch angle, i.e., the amount of change in pitch angle, using the amounts of correction set for each roll angle, and controls the optical axis angles using the corrected pitch angle, the each roll angle being obtained during stop of the vehicle.
