Abstract
A method for changing at least one light emission parameter of a headlamp system or a vehicle headlamp of a motor vehicle based on changing ambient light conditions. The light emission parameters of the headlamp system are stored in a memory of a computer at the factory. The ambient light conditions in the driving direction of the motor vehicle are detected by a sensor and forwarded to the computer. Actual light emission parameters of the headlamp system and the ambient light condition are compared and a change of at least one of the light emission parameters of the headlamp system or the vehicle headlamp in accordance with the ambient light conditions forwarded is determined that a predefined or predefinable threshold value or limiting value of the current actual light emission parameters is exceeded.

16. A headlamp system for a motor vehicle comprising:
-
a headlamp having at least one light emission parameter; a sensor configured to detect an ambient light condition and convert the ambient light condition into an ambient light signal, wherein the ambient light condition is not emitted by the headlamp in front of a motor vehicle; a headlamp controller configured to; store the at least one light emission parameter; compare a current actual light emission parameter with the ambient light signal acquired from the sensor; change the at least one light emission parameter in accordance with the ambient light signal when a control value for the current actual light emission parameter is reached; and store the changed light emission parameter as an updated light emission parameter for a subsequent comparison with the ambient light signals acquired from the sensor. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

28. A method for changing at least one light emission parameter of a headlamp system of a motor vehicle in response to changing ambient light conditions, the method comprising:
-
storing a current actual light emission parameters of the headlamp system in an intermediate memory of a computer at the factory; detecting ambient light conditions in the driving direction of the motor vehicle by a sensor and forwarding to the computer; comparing the current actual light emission parameters of the headlamp system and the ambient light conditions forwarded by the sensor with one another by the computer initiating a change of at least one of the light emission parameters of the headlamp system by the computer in accordance with the ambient light conditions forwarded by the sensor when it is determined that a control value of the current actual light emission parameters is exceeded; and transmitting the updated light emission parameter to the intermediate memory as new updated actual light emission parameter. - View Dependent Claims (29, 30, 31, 32, 33)
