Abstract
A motor vehicle headlight and method for operating the headlight is disclosed, wherein the headlight is operated in a main beam mode or in a partial main beam node. A light distribution of the main beam of the headlight is adapted as a function of a course of a road which is being traveled along by the motor vehicle. In addition, a motor vehicle headlight is described.
Claims16
A method for operating a headlight of a motor vehicle comprising:
- determining a road course for a road on which the motor vehicle is traveling;
- selecting a mode of operation for the headlight as a function of the road course, wherein the mode of operation is selected from the group consisting of a main beam mode and a partial beam mode;
- operating the headlight in the selected mode of operation such that a light distribution of a main beam of the headlight is adapted to the road course;
- adapting the light distribution in a first stage and in a second stage;
- and
- activating a first side reflector in the first stage and activating the first side reflector and a second side reflector in the second stage.
A motor vehicle headlight assembly for a motor vehicle comprising:
- a fixed headlight having a main beam operable to emit a light distribution therefrom, a first side reflector configured to provide lateral illumination and a second side reflector configured to provide additional lateral illumination;
- and
- a controller configured to:
- adapt the light distribution of the main beam as a function of a road course of a road on which the motor vehicle is traveling;
- adapt the light distribution in a first stage and in a second stage;
- activate the first side reflector in the first stage;
- and
- activate the first side reflector and the second side reflector in the second stage.
A method for operating a headlight of a motor vehicle comprising:
- determining a road course for a road on which the motor vehicle is traveling;
- selecting a mode of operation for the headlight as a function of the road course, wherein the mode of operation includes a main beam mode and a partial beam mode;
- operating the headlight in the selected mode of operation such that a light distribution of the headlight is adapted to the road course;
- altering the light distribution in a first stage wherein a first side reflector adapted to provide lateral illumination is activated;
- and
- alerting the light distribution in a second stage wherein the first side reflector and a second side reflector adapted to provide additional lateral illumination are both activated.
