Methods and apparatus for driving an emitter array are described. A method includes determining a thermal environment profile for a plurality of emitters of the emitter array, computing a current pulse profile for at least one of the plurality of emitters based on the thermal environment profile, and applying a current pulse with the computed current pulse profile to the at least one of plurality of emitters.

A method for operating a vehicle in at least one parking process situation involves allocating at least one predetermined vehicle-specific or parking process situation-specific function to the at least one predetermined parking process situation of the vehicle. Whether the vehicle is in the at least one predetermined parking process situation is determined and the predetermined vehicle-specific or parking process situation-specific function allocated to the at least one predetermined parking process situation is presented to a vehicle user for activation or automatically activated when the vehicle is in the at least one predetermined parking process situation.

Provided is a method and device to selectively illuminate off-road objects in low-light environments using directionally-adjustable vehicle headlamps. An object may be identified by a vehicle user and/or autonomous vehicle sensors. When the identified object is within an illumination range capability of a vehicle headlamp, a frontlighting control unit operates to determine vector data for the identified object, taking into account vehicle motion. With the vector data, a headlight pattern of the vehicle headlamp may be adjusted to align with the vector data to illuminate the identified object.
