Method, control unit and computer program to determine a head orientation and/or head position of a vehicle occupant

A control unit for automated driving functions, comprising:

• at least one interface configured to obtain data from a first imaging sensor and a second imaging sensor, the data comprising sensed head orientations or head positions of a vehicle occupant;
• a computer comprising a memory storing a first detection range of the first imaging sensor for sensing head orientations or head positions based on various head orientations or head positions in relation to a position of the first imaging sensor, and storing a second detection range of the second imaging sensor for sensing head orientations or head positions based on various head orientations or head positions in relation to a position of the second sensor, wherein the computer is configured to determine, based on the sensed head orientation or head position of the vehicle occupant from the first imaging sensor and the second imaging sensor at least one of a determined head orientation or a determined head position with at least one sensor of the first or second imaging sensors that has a detection range in which the sensed head orientation or head position can be better determined than a detection range of another sensor, and determine a signal based on the at least one of the determined head orientation or the determined head position of the vehicle occupant;
• and
• a second interface for outputting the signal.
