Abstract
A headlight for vehicles, having a light source unit for emitting light, an optical unit for deflecting the light in accordance with a predefined light distribution, and a control unit for generating a control signal, by means of which the light source unit and/or the optical unit can be controlled, wherein the control signal is generated depending on a number of environmental parameters, wherein an optimization program is stored in the control unit, by means of which optimization program the control signal is calculated from a plurality of individual control signals, wherein by means of the individual control signals different partial light distributions, each dependent on the environmental parameters, can be generated.
Claims13
A headlight for vehicles, the headlight comprising:
- a light source unit that emits light;
- an optical unit to deflect the light in accordance with a predefined light distribution;
- and
- a control unit to generate a control signal, the light source unit and/or the optical unit being controlled by the control unit,
- wherein the control signal is generated depending on environmental parameters,
- wherein an optimization program is stored in the control unit, the control signal being calculated, via the optimization program, from a plurality of individual control signals,
- wherein, via the individual control signals, different partial light distributions, each dependent on the environmental parameters, are generated,
- wherein the control unit is coupled to a detection unit provided in the vehicle to detect the environmental parameters and to an external transmission device that is provided external to the vehicle to detect the environmental parameters, the external transmission device transmitting the environmental parameters to the control unit via a communication network, and
- wherein the optimization program is designed such that the respective environmental parameters that are currently provided by the external transmission device are compared for correspondence with the respective environmental parameters that are currently provided by the detection unit, and wherein, if a deviation is detected between the respective environmental parameters, the respective environmental parameter provided by the detection unit is used to form the individual control signal.
