摘要:
A control device (100) of a vehicle lamp (10) includes: a receiving section (102) which receives an acceleration value usable to derive a tilt angle (Θ) of a vehicle to a horizontal plane, wherein the tilt angle of the vehicle to the horizontal plane is represented as a total angle (Θ); and a control section (104) which controls an optical axis adjustment of the vehicle lamp. The control section derives from the total angle a first and a second provisional vehicle posture angles (Θv1, Θv2) based on a first and a second calculation method, respectively, corrects the first or second provisional vehicle posture angle so that a difference between the first and the second provisional vehicle posture angles becomes small, sets the corrected provisional vehicle posture angle to the vehicle posture angle (Θv), and outputs a control signal for instructing the optical axis adjustment of the vehicle lamp according to the vehicle posture angle.

A vehicle lamp controller (228R,228L,302), a vehicle lamp system, and a vehicle lamp control method are provided. The vehicle lamp system includes an acceleration sensor (316), a vehicle lamp (10), and the vehicle controller. The controller includes a receiver (228R1,228L1) configured to receive an acceleration information detected by the acceleration sensor (316), a control unit (228R2,228L2) 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 (O) of the vehicle lamp (10), 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 (300), and a transmitter configured to transmit the control signal to an optical axis adjusting portion (236,226) of the vehicle lamp (10).

The invention relates to a headlight having a plurality of luminescent diode emitters. Of the luminescent diode emitters, at least one first group is disposed in a matrix having at least two columns and at least two rows, wherein in the first group the electrical connections of a first connection type of the luminescent diode emitter of a column and the electrical connections of a second connection type of the luminescent diode emitters of a row are electrically connected to each other. The electrical connections of the first connection type of different columns and the electrical connections of the second type of different rows of the matrix are electrically isolated from each other.

A system for regulating the position of the chassis (2) of a motor vehicle has actuators which are to be set by means of actuating signals of a regulating and control unit, wherein the position of the chassis or of a part of the chassis is measured by means of a distance sensor (4), and an adjustment is carried out by means of the actuators if the measured sensor signals of the distance sensor deviate from predefined nominal values. Arranged on the vehicle underside, at at least three spaced-apart positions, is in each case one path-measuring sensor arrangement (3) having a non-contact distance sensor, by means of which at least two path measurements in different directions (5, 6, 7) can be carried out.
摘要:
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Steuern der Lichtabgabe mindestens eines Frontscheinwerfers eines Fahrzeugs. Mit Hilfe einer Bilderfassungseinheit (12) werden mehrere Bilder mit Abbildungen mindestens eines Objekts (16) nacheinander als Bildfolge erfasst. Die Position des Objekts (16) wird in mindestens zwei der nacheinander als Bildfolge aufgenommenen Bilder ermittelt. Mit Hilfe der ermittelten Positionen wird eine durch die Fahrzeugbewegung bewirkte Nickwinkeländerung des Fahrzeugs (10) ermittelt. Die Lichtabgabe des Frontscheinwerfers (18) des Fahrzeugs wird abhängig von der ermittelten Nickwinkeländerung gesteuert.
摘要:
The present invention aims to perform optical axis adjustment while a vehicle is stopped only in necessary situations and to avoid unnecessary adjustment, and to further enhance durability. A headlight optical axis adjustment device (10) for adjusting an optical axis of a headlight based on a pitch angle of the vehicle includes an opened/closed state detection section (22) for detecting an open/closed state of an open/close unit where the opened state is when a passenger gets on/out or when a baggage is being loaded/unloaded to and from the vehicle; and an optical axis adjustment permitting section (26) for permitting optical axis adjustment of the headlight based on the pitch angle of the vehicle when the opened state of the open/close unit is detected by the opened/closed state detection section.
