DE102008006872A1 - Motor vehicle for traveling through forest, has illumination system with high beam and low beam, where conical light of low beam is tilted towards side in front of motor vehicle, while high beam is switched on - Google Patents

Abstract

The vehicle (1) has an illumination system with a high beam (2) and a low beam (3), where a conical light of the low beam is tilted towards the side in front of the vehicle, while the high beam is switched on. The conical light of the low beam in left is tilted to right and the conical light of the low beam in the right is tilted to left around a common angle. The high and low beams are formed with separate headlights. The tilting angle of the low bean is changed depending of speed of the vehicle. A sensor is provided in the vehicle to detect the light coming out from the headlight.

Description

The The invention relates to a motor vehicle with a lighting system with a high beam and a low beam.

motor vehicles have a lighting system with one Low beam or driving lights as well as an optionally switchable high beam. Furthermore, it is known, lateral or laterally ahead lying areas the roadway with static or adaptive lighting elements illuminate. For example, on a front side Area of the motor vehicle fixedly arranged bulbs provided for example, when approaching an intersection, the lateral To illuminate areas additionally. It is also known a headlamp or the light cone of the headlamp around a to pivot vertical axis, if necessary depending from the vehicle speed to when cornering the in better to illuminate the lane ahead of the curve.

The DE 103 54 088 A1 describes an adaptive headlamp system for motor vehicles, in which both a beam of a high beam and a low beam are designed to be pivotable sideways together to keep an improved illumination of curved areas to it. The beams are only pivoted to one side.

The DE 103 42 592 A1 discloses a method for driving a vehicle headlight, which is controlled only when driving on unpaved terrain in such a way that an environment is better illuminated.

Furthermore, it is from the DE 103 13 731 A1 in a reverse drive of a motor vehicle, in particular for parking, to activate an additional parking light for illuminating rearward areas.

Finally, the shows DE 10 2004 007 782 A1 a vehicle with an exterior lighting system with a side light element, which can only be activated if a distance from a side distance sensor to other vehicles on adjacent lanes detected.

at Although the known motor vehicles may have sufficient lighting from lying ahead areas, especially when cornering realized but, especially on longer trips, For example, on rural roads, on straight roads Lateral areas ahead not sufficiently illuminated become.

It is the object of the invention, a motor vehicle of the aforementioned Way of creating, with the improved illumination ahead lateral areas is possible.

According to the invention solved the problem that when the high beam a beam of the low beam is swiveled to the side.

at Such a trained motor vehicle, the two Light cone of the light sources for the dipped beam during the normal driving operation to the side to the outside be pivoted. The dipped lights are additional switched on to the activated high beam. This only happens then, when the high beam of the lighting system of the motor vehicle The driver was activated, which is usually only then is executed if no immediately preceding Motor vehicle or oncoming road users present are, since these are not to be dazzled by the high beam. In In this case, by pivoting the light cone of the Low beam to the outside and the laterally ahead Areas better viewed through the additional illumination and be monitored. Thus, for example When driving through a forest wild animals are detected faster and evasive maneuvers be initiated. In an embodiment, the left front dipped beam is to the left and the right front dipped beam to the right, in particular each pivotable at the same angle. In principle, alternatively even just one cone of light alone or both beams around a different one Angles are pivoted.

in the The scope of the invention is encompassed in that either an entire Headlamp unit for the low beam around a substantially vertical axis can be pivoted or just the cone of light, for example, by a relative movement of the lamp itself or a reflector in the headlight. Will the high beam from the driver deactivated, the light beams of the dipped beam become again after aligned straight ahead, for example, an oncoming Road users by the lateral illumination not to dazzle.

Becomes of the motor vehicle drive a curve, so may possibly existing static curve lights are switched on and / or the light cones of an adaptive illumination system become corresponding the steering wheel angle or the speed in itself aligned in a known manner.

The advantage of the invention is that practically only existing in the motor vehicle components, preferably from a central Control unit, must be controlled, which requires only minor hardware and / or software modifications that cause virtually no additional effort in the production.

In Advantageous embodiment form the high beam and the low beam a common headlamp unit, allowing a pivoting of the additional for high beam dipped beam, for example, by a Displacement of the bulb for the low beam relative to the common headlamp unit or by turning a reflector can be done at a desired angle. In the same Way, the low beam and the high beam can each over a separate headlamp unit at the front of the vehicle , whereby the pivoting of the low beam through the pivoting of the entire headlight can be done.

Preferably is a pivot angle for the additionally activated Dipped beam speed-dependent adjustable. there can the Verschwenkungswinkel with increasing vehicle speed be reduced as the driver at higher speeds practically no longer monitor the lateral areas can. In contrast, with decreasing vehicle speed the beams of the dipped beam farther outward pivoted, for example, house numbers on a row of houses to be able to read better.

Around to avoid glare from oncoming traffic On the motor vehicle, a sensor is provided, the light of the more responsive Headlamps detected and exceeding a limit value transmits a corresponding signal to a control unit, so that the outwardly pivoted light cone of the low beam be turned back to its normal position.

It It is understood that the above and below to be explained features not only in the specified Combination, but also usable in other combinations. The scope of the invention is defined only by the claims.

The Invention will be described below with reference to an embodiment explained in more detail with reference to the drawing. The sole figure of the drawing shows an inventive Motor vehicle in a schematic representation.

The car 1 has a lighting system with a high beam 2 and a low beam 3 , The high beam 2 is the driver of the motor vehicle 1 only switched on when there are no vehicles in front of the vehicle as well as no oncoming road users.

In this case, the light cones of the low beam 3 be pivoted to the side to the outside, around the lateral and laterally facing areas in front of the motor vehicle 1 additionally illuminate.

It can either the headlights of the dipped beam 3 be pivoted in total or just the light cone of the dipped beam 3 in a known manner.

The degree of pivoting of the light cone of the low beam 3 can be changed so speed-dependent that decreases with increasing vehicle speeds, the Verschwenkungswinkel.

Of course, when cornering more static or adaptive. Turn lights turn on. Likewise, a sensor may be provided which detects the headlight of an oncoming traffic participant and an alignment of the low beam 3 To prevent dazzling this road user forward straight forward.
