Problems solved by technology

[0005] The disadvantage of the known headlights is that the control of the headlights as a function of the steering wheel angle and the speed of the vehicle, especially during short and fast steering movements, although this does not actually lead to a change in the driving direction, is nevertheless controlled by the headlights. rotated, and thus not adequately illuminated in road curves
In addition, when the vehicle understeers, there is the effect that the headlights are illuminated too far into the inner side of the curve, and the outer edge of the road is not illuminated sufficiently

Embodiment Construction

[0019] The headlight 1 can be pivoted about a vertical axis 2 (indicated in the figure by the double-headed arrow 6 ) in order to emit a beam cone 3 in different directions. As a result, either the entire headlight 1 or only the reflector 5 can be moved, or the luminous means or the visor can be moved relative to the reflector 5 . To deflect the headlight 1 , servo motors are used, which are controlled by a control unit 4 (shown as connecting line 7 ).

[0020] The control device 4 can be informed, for example, of the current driving situation of the vehicle by means of ESP system signals, wherein the control device 4 can use this signal to determine unstable driving situations, in particular understeer or oversteer. As soon as the control device 4 registers such an unstable driving situation, this can be taken into account when adjusting the direction of the headlights or the beam cone. For example, when understeering (which will cause the headlights to irradiate excessively...

Abstract

A headlight (1) in a motor vehicle which can be rotated about a vertical axis (2) during cornering has a control device (4) for controlling the rotational movement. Unstable driving situations can be taken into account by the control device (4) in order to improve the lighting of a carriageway located in front of the motor vehicle.

Description

technical field [0001] The invention relates to a motor vehicle headlamp which is rotatable about a vertical axis when cornering and has a control device for controlling the swivel movement. Background technique [0002] Especially new cars and high-end cars are more and more widely used and can produce headlights suitable for the lighting of the road ahead of the car during driving. The light emitted by such headlights is no longer just stationary or sent straight or in a certain direction, but the headlights, especially their reflectors, are designed in such a way that, thus, when turning When driving, it can also illuminate the oblique front area of ​​the car to avoid hitting obstacles that are not illuminated at the turn. For this purpose, the beam cone emitted by the headlight can be pivoted or rotated about a substantially vertically oriented vertical axis. This includes situations where either the entire headlamp or only a part thereof, such as the reflector or only...
