Adaptive headlights for the trajectory of a vehicle

A computer program product comprising:

• one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising:
• program instructions to receive information relevant to the trajectory of a vehicle, wherein the information relevant to the trajectory of the vehicle includes:
• a planned path of a user of the vehicle, a position and trajectory of the vehicle at a particular time, a map of a road network, a model of an illumination of the road network, a model of a terrain, and data from sensors;
• program instructions to estimate the position of the vehicle at the particular time on the trajectory of the vehicle, using the data from the sensors;
• program instructions to estimate an illumination of the trajectory of the vehicle, using the model of the illumination of the road network and the data from the sensors, wherein a threshold is employed for combined luminous flux of at least one headlight, streetlight, and ambient light at the particular time;
• program instructions to determine the threshold is exceeded, wherein the exceeded threshold reveals there is not enough light present from the combined luminous flux of the at least one headlight, the streetlight, and the ambient light at the particular time;
• program instructions to change a setting of the at least one headlight on the vehicle;
• subsequent to changing the setting of the at least one headlight on the vehicle, program instructions to determine the threshold is exceeded;
• and
• program instructions to alert the user of the vehicle when adjustments to the at least one headlight that are necessary to illuminate the trajectory of the vehicle exceed physical limitations of the at least one headlight, wherein the combined luminous flux of the at least one headlight, the streetlights, and the ambient light is not enough to illuminate the trajectory of the vehicle at the particular time.
