Provided are: an inclination angle calculating unit for calculating, when having determined that a vehicle is stationary by referring to vehicle information indicating a traveling state of the vehicle, an inclination angle of the vehicle during a stationary period using inclination angle information indicating an inclination angle of the vehicle and determining a vehicle inclination angle during the stationary period from the calculated inclination angle of the vehicle; and a correction determination processing unit for determining whether an absolute value of a difference between the determined vehicle inclination angle and a reference angle determined previously by the inclination angle calculating unit is less than a first threshold value (threshold value ) and, if the absolute value of the difference is less than the first threshold value (threshold value ), performing a correction to rewrite the vehicle inclination angle to the reference angle.

A method for adjusting a distribution of light from a headlight of a first motor vehicle in order to avoid the headlight blinding of dazzling a driver of a leading vehicle travelling ahead of and in the same direction as the first vehicle. The method includes: detecting a following distance between the vehicle and the leading vehicle on an initial road section; operating the headlight at a first illumination range less than or equal to the following distance; detecting a directionally-deviating road section ahead of and having a direction different from the initial road section; detecting that the leading vehicle has moved beyond a transition between the initial road section and the directionally-deviating road section; operating the headlight at a second illumination range not extending beyond the transition; and operating the headlight at the first illumination range after the vehicle reaches the transition.

A control device for a vehicle lamp including an ECU configured to: i) receive a sensor signal and derive a total angle; ii) retain an initial set value of the vehicle posture angle, the initial set value being acquired in an initialization process; iii) retain a reference value of the vehicle posture angle, adjust an optical axis angle of the vehicle lamp in response to a change amount of a total angle during a stop of the vehicle, and retain a sum of the change amount of the total angle and the reference value of the vehicle posture angle as a new reference value; iv) not adjust the optical axis angle in response to a change amount of a total angle during traveling of the vehicle; and v) perform a predetermined reset process when a reset signal is received.

A vehicle comprises a head lamp which irradiates a head lamp irradiation region set in front of a vehicle body; an auxiliary lamp which irradiates an auxiliary lamp irradiation region set in front of the head lamp irradiation region; a bank state detecting section which detects a bank state of the vehicle body; and a lighting control section which lights the auxiliary lamp depending on the bank state, the lighting control section causes the auxiliary lamp to be lighted in a set lighting state when the bank state detecting section detects a predetermined set bank state, and the lighting control section causes the auxiliary lamp to be lighted in a preceding lighting state at luminosity lower than that of the set lighting state, when the bank state detecting section detects a preceding bank state which occurs before the vehicle body reaches the set bank state.

A motor vehicle according to an exemplary aspect of the present disclosure includes, among other things, a sensor, a headlamp, and a controller configured to adjust an aim of the headlamp based on a signal from the sensor. The controller is configured to account for a zero drift of the sensor. A method is also disclosed.

A vehicle may have lights such as headlights. The lights may be moved using a positioner. Control circuitry in the vehicle may use sensor circuitry to monitor the environment surrounding the vehicle. The sensor circuitry may include one or more sensors such as a lidar sensor, radar sensor, image sensor, and/or other sensors to measure the shape of a surface in front of the vehicle and the location of the surface relative to the vehicle. These sensors and/or other sensors in the sensor circuitry also measure headlight illumination on the surface. Based on the known shape of the surface in front of the vehicle and the distance of the surface from the vehicle, the control circuitry can predict where a headlight should be aimed on the surface. By comparing predictions of headlight illumination on the surface to measurements of headlight illumination on the surface, the vehicle can determine how to move the headlight with the positioner to align the headlight.
