发明名称 Method and device for adjusting a beam direction of a headlight, and motor vehicle
摘要 A method for adjusting a beam direction of a headlight of a vehicle having at least one front wheel and at least one rear wheel includes the following steps: a) detecting a front wheel steering angle of the at least one front wheel; b) detecting a rear wheel steering angle of the at least one rear wheel; c) defining a beam direction of the headlight depending on the front wheel steering angle and the rear wheel steering angle; and d) adjusting the beam direction of the headlight to the defined beam direction. The adjustment depends on whether the rear-wheel steering angle and the front wheel steering angle are oriented in the same direction or in opposite directions.

主权项 1. A method for adjusting a beam direction of a headlight of a vehicle with at least one front wheel and at least one rear wheel, the method comprising the steps of: a) detecting a front wheel steering angle of the at least one front wheel, a1) defining a comparison beam direction of the headlight as a function of the front wheel steering angle without taking into consideration the rear wheel steering angle, b) detecting a rear wheel steering wheel angle of the at least one rear wheel; c) defining a beam direction of the headlight as a function of the front wheel steering angle and the rear wheel steering angle, wherein in the event that the rear-wheel steering angle and the front wheel steering angle are oriented in opposite directions in relation to a respective neutral position of the associated rear wheel or front wheel, the beam direction is defined at step c) so as to be oriented more strongly in the direction of the front wheel steering angle in relation to the comparison beam direction,andin the event that the rear-wheel steering angle and the front wheel steering angle are oriented in an identical direction in relation to the respective neutral position of the associated rear wheel or front wheel, the beam direction is defined at step c) so as to be oriented less strongly in the direction of the front wheel steering angle in relation to the comparison beam direction, andd) adjusting the beam direction of the headlight to the defined beam direction.
