Definitions
- the present invention relates to a method and for determining a road quality, to a corresponding device and to a corresponding computer program product.
- aCOL Adaptive Cut-off line
- a safety angle is set to the desired angle of the headlights.
- the safety angle is to prevent dazzling of the opponents, for example due to inadequacies in the measurement or especially in uneven floors.
- bridges or level crossings in the road are a particular challenge, since they have thresholds and / or expansion joints, which cause a pitching of the vehicle when driving over.
- Road quality optimized safety angle can be adjusted.
- the pitch rate or pitch angle is evaluated. If large fluctuations occur, it is assumed that the road quality is poor. It is then set a large safety angle. If there are hardly any fluctuations in the pitch values, it is assumed (after some time, eg 20 s) that the
- Transition to a good road quality is delayed because of the assumption of a constant road quality as preventive glare avoidance.
- An alternative concept proposes a standardization of the road quality to enable a quick reaction of the safety angle to changes in speed. At high speeds, bumps have a greater effect on pitch behavior than at low speeds.
- the standardization gives a measure of the road quality with which a speed-dependent safety angle can be meaningfully determined.
- a pronounced pitching movement of a vehicle can be integrated into the method such that at the same time a glare
- the z. B. indicate a presence of a bridge.
- a temporary lowering of the headlights or a temporary increase in a safety angle for a headlight inclination can be realized so as not to dazzle opponents when driving over a bridge threshold, for example.
- the determination of the road quality can be suspended in order not to falsify a possibly necessary long measurement of the pitching behavior by extreme values which may be measured when crossing the sleepers of a bridge. It can thus be advantageously prevented that a strong pitching motion of the vehicle causes the road quality tends to be rated worse.
- the effect of a temporary, locally limited, lower road quality has thus little or no effect on the. According to the approach presented here
- Road quality estimation used to adjust the safety angle as the assumption that the determined road quality remains constant over a longer period of time can be replaced by a concrete calculable time window for road quality deterioration according to the approach presented here.

- the lane state information may indicate an existence or a presence
- Road condition information provide this hint before the vehicle has reached the lane section marked by the particularity.
- Such thresholds exist z. B. in the driveway on and departure from bridges and at
- a headlamp system of the vehicle may be controlled with sufficient lead time such that an oncoming vehicle is not dazzled by the headlights of the ego vehicle.
- the method comprises a step of reading in the road condition information. It can the
- Road condition information come from different sources, so be provided by a suitable device in the vehicle or outside the vehicle.
- the reading of the road condition information can be repeated, for example, at predetermined intervals.
- the method may include a step of tilting at least one headlamp of the vehicle for a predetermined period of time based on the additional parameter.
- the predetermined period may be specified by a content of the road condition information.
- the inclination of the headlights of the vehicle can be carried out for example by a high beam assistant of the vehicle, which uses the method according to the invention.
- the predetermined period may correspond to a travel time for traversing the specificity of the road ahead road section specified by the road state information.
- This embodiment offers the advantage that a period of the headlight inclination so as not to dazzle a driver of an oncoming vehicle can be kept as short as possible.
- the driver of the vehicle using the method has thus at the earliest possible time again optimal view of the lying in front of him track section.
- the tilting of the headlamp can be implemented differently depending on the actual realization.
- a mechanical pivoting of the headlamp or a headlamp module e.g., lens in a
- Projection system is also a change in the light distribution possible.
- the emission angle of the cut-off line can be lowered, which is obvious in adaptive systems such as AHC.
- Implementation of the headlamp can be done for example by changing a diaphragm in the headlight (subtractive generation of light distribution) or, for example, by switching off or dimming individual areas (additive light generation, for example, in LED headlamps).
- a horizontal safety angle can be increased so as not to blind other vehicles during the rolling motion of the vehicle.
- the method may include a step of increasing a safety angle with respect to a determination of a degree of inclination of the at least one headlamp for a predetermined period of time based on the
- the predetermined period may be specified by a content of the road condition information.
- Oncoming vehicle can be ensured against glare, as well as an insufficient inclination of the headlights due to, for example, measurement or calculation errors effectively and easily
- the method may include a step of suspending the determination of the road quality for a predetermined period of time based on the additional parameter.
- the predetermined period may be specified by content of the road condition information.

- the content of the traffic sign may mark the road section in front of the vehicle as a bridge and / or a railroad crossing.
- the optical sensor may be a camera of the vehicle.
- the content of the traffic sign may be the road section ahead of the vehicle as having a deteriorated road section
- the method proposed here can advantageously be extended to include detection of further potential causes for pronounced pitching motion of the vehicle.

- a first graph 804 shows a pitch angle profile of a vehicle before, during and after crossing the threshold. As graph 804 shows, in the beginning there is a slight sway that results from the road quality. At 800, the military shield 316 can be seen, often placed in front of bridges. At 802, a large rash of pitch angle is observed as the vehicle has crossed the threshold of the bridge. After crossing the threshold is the
- a second graph 806 is illustrative of conventional implementations for adjusting the tilt or safety angle of headlamps
- An increase in the graph at 802 indicates here an increase in the safety angle at the headlight inclination.

- Determining the road quality is indicated by a different representation of the graph 810 by means of a dashed line. As shown in FIG. 8, suspension of determining the road quality begins shortly after the time 800 of recognizing the character 316 and ends at a time 814 indicated by a third dot line crossing the graphs. As already explained, a duration of the predetermined Period 812 determined based on the additional parameter. After the threshold, the road quality is still determined to be "normal". By suspending the determination of road quality, the driver has a good view of the threshold, as he continues to be (justified) on a good road
- the safety angle is correspondingly smaller than for the settings illustrated by graphs 806 and 808. It is advantageous in this method that the driver of the ego vehicle does not notice the suspension of the determination of the road quality, since the determination takes place within the system. A lowering at a falsely recognized bridge does not occur here.
- a fifth graph 816 illustrates a particularly advantageous embodiment of the concept presented here, namely the combination of the exemplary embodiments explained with reference to graphs 808 and 810 of the preventive increase of the safety angle and the suspension of the determination of the road quality.
- the inventive analysis of the road signs 316 can be used even if no direct determination of the road quality is performed, for example, to adjust a fixed safety angle. Since the signs 316 indicate an insufficient road quality in the broader sense, the safety angle can be adjusted or increased without explicitly measuring the road quality. It is advantageous to save the computing power in determining the road quality. A possibly inaccurate adjustment of the safety angle and the lack of opportunity to accurately recognize a good road quality again - as it is unclear when a sign will lose its validity - is to be accepted in this case.
- a lane condition information is read in which is a condition of one in a traveling direction ahead of
