Description

TECHNICAL FIELD

[0001] The invention relates to a method for controlling a headlight of a vehicle. The invention also relates to a headlight for carrying out the method. BACKGROUND

[0002] In a headlight, in particular a headlight, individual anti-dazzle regions can be arbitrarily set.

[0003] A headlight arrangement for a motor vehicle is known from US 9 764 683 B2. The headlight arrangement comprises a segmented light source with individually switchable light source segments for generating a non-dazzling high beam by means of an automatic anti-dazzle system. The headlight arrangement is configured such that by deactivating individual light source segments, one or more regions in the main light distribution of the headlight arrangement can be purposefully suppressed. In the activated state, each light source segment illuminates a main light segment region in the main light distribution of the headlight with a respective preset width. The width of the high beam segment region is preset in accordance with the expected average dynamics of the objects in order to avoid dazzling in normal traffic conditions.

[0004] Disadvantageously, individual so-called "tunnels" are produced by the individual deactivated light source segments, which tunnels affect the perception of the driver. In particular, the individual "tunnels" affect the driving experience. In this respect, different drivers have different preferences. In particular, the setting of the headlight cannot be decided by the driver himself. SUMMARY

[0005] It is now an object of the present invention to propose a method and a headlight which overcome the above-mentioned disadvantages.

[0006] According to the invention, this object is achieved by a method having the features of claim 1, in particular the features in the characterizing part of claim 1. Advantageous design solutions and refinements are given in the dependent claims. Furthermore, a headlight for a motor vehicle is described.

[0007] In the core idea of the method according to the invention, the number of selected anti-dazzle regions can be selected by the driver and / or adjusted in accordance with a selected driving program. Thereby, the wishes of different drivers can be taken into account. This is in particular advantageous for high-resolution headlamps, which can have a large number of anti-dazzle regions. The driver can also select a stored program here himself in order to ensure the desired number of anti-dazzle regions. Furthermore, the number of selected anti-dazzle regions can be adjusted in accordance with a selected preset program, for example by recognizing whether the vehicle is on a country road, a motorway or an urban road. Furthermore, the vehicle speed and the driving style of the driver can be taken into account.

[0008] This method is designed to control the headlights of a vehicle, where each headlight has multiple possible anti-glare zones. For example, this method can be used when the high beam pattern becomes unstable due to the large number of anti-glare zones when using methods or devices known in the prior art. Because it caters to different driver needs, a setting that provides driver comfort can be found.

[0009] Preferably, each headlight can have up to 120 anti-glare zones. This allows for highly personalized settings for each individual headlight. A large number of so-called "dark zones" can be provided, where the efficiency of high beams is improved because individual headlights do not need to be merged into single beams.

[0010] A highly advantageous improvement to this idea is that it can be configured to selectively illuminate individual objects, with at least one anti-glare zone between objects. This, for example, avoids large light cones. Furthermore, it avoids illuminating unwanted areas between two objects.

[0011] Here, according to an advantageous design, the number of anti-glare zones can be selected between 10 and 120 depending on the driving program. Specifically for high-resolution headlight technology, it is feasible to provide up to 120 anti-glare zones. It is also feasible to provide more than 120 anti-glare zones in a specific headlight design.

[0012] Another advantageous design could be to configure the driving program to include an economy mode, a normal mode, and a dynamic mode. In economy mode, 10 anti-glare zones can be selected; in normal mode, 30 anti-glare zones can be selected; and in dynamic mode, 120 anti-glare zones can be selected. For example, in dynamic mode, 120 so-called "dark zones" could be created at different locations. In normal mode, for example, 30 "dark zones" could be created, and in economy mode, 10 independent "dark zones" could be created. Of course, other modes could be provided, each offering a different number of anti-glare zones. For example, economy mode could also include 5-20 anti-glare zones, normal mode could include 20-70 anti-glare zones, and dynamic mode could include 70-120 anti-glare zones.

[0013] A highly advantageous improvement to this idea is that the anti-glare zone can be selected via an application. This application could be, for example, a vehicle-connected app. Data could be provided in the cloud. The application could be operated, for example, on a smartphone or tablet. Similarly, the application could be integrated into the vehicle itself and controlled via an in-vehicle app, particularly on a display screen. The driver could, for example, select a driving program or the desired number of anti-glare zones via the application.

[0014] Here, according to an advantageous design, the anti-glare zone can be selected based on the driving route. For example, if GPS data is stored, the required number of anti-glare zones can be provided based on the optimal driving procedure for the route, particularly depending on the individual driver.

[0015] Another advantageous design option is to use DMD headlights or μLED headlights. Such headlights can provide a particularly advantageous solution for achieving a large anti-glare area.

[0016] The present invention also relates to a headlight for a vehicle performing the method, wherein the headlight has multiple anti-glare zones that can be selected by the driver or coupled to a driving program. The same features and advantages as described with respect to the method apply to the headlight. In particular, the headlight can be constructed such that it can achieve different method features.

[0017] The invention may also include vehicles having such headlights. Furthermore, the invention may include vehicles designed to perform the methods of the invention.

[0018] The method according to the invention, as well as more advantageous designs of the headlights according to the invention, are also derived from the embodiments described in detail below in conjunction with the accompanying drawings. Attached Figure Description

[0019] in:

[0020] Figure 1 A vehicle is shown, which is performing one possible implementation of the method. Detailed Implementation

[0021] Figure 1 The illustration shows one possible implementation of method 1. Method 1 is designed to control the headlights 2 of a vehicle 3, wherein each headlight 2 has multiple possible anti-glare zones 4. In the illustrated embodiment, an anti-glare zone 4 is depicted pointing towards oncoming vehicles. This anti-glare zone 4 can be selected, for example, by the driver and / or adjusted according to a selected preset program.

[0022] Vehicle 3 features high-resolution headlight technology, such as DMD headlights or μLED headlights, enabling the headlights 2 to achieve a large number of anti-glare zones 4. Preferably, each headlight 2 may include, for example, up to 120 anti-glare zones 4. Thus, different modes, such as economy mode, normal mode, and dynamic mode, can be stored in vehicle 3, each with a different number of anti-glare zones 4.

[0023] The two headlights 2 can react synchronously with each other, selecting the corresponding identical anti-glare zone 4. Alternatively, each headlight 2 can be controlled individually for personalized lighting effects. The selection of the anti-glare zone 4 can be made by the driver, for example, via an app in the vehicle 3 or an app on a smartphone or tablet. Furthermore, the selection of the anti-glare zone 4 can be adjusted according to stored driving programs. Therefore, if a driving program is selected, a corresponding number of anti-glare zones 4 are provided.

[0024] Figure 1 The anti-glare area 4 shown is merely an example, and multiple such anti-glare areas 4 can naturally be formed if different objects are to be presented in the so-called "dark area".
