Method for detecting an occupancy state

A method for detecting an occupancy state of at least one seat in a vehicle having a vehicle interior, the method comprising:

• receiving, by a control unit:
• a first plurality of channel impulse responses that is specific to reflections of first ultrawideband (UWB) waves in the vehicle interior,
• a fourth plurality of channel impulse responses that is specific to reflections of second UWB waves in the vehicle interior, and
• a second plurality of channel impulse responses that is specific to reflections of first UWB waves in the vehicle interior, or a third plurality of channel impulse responses that is specific to reflections of second UWB waves in the vehicle interior;
• detecting, by the control unit, a first target by a first detection algorithm, whereby a first target detection is provided, which is specific to the first target, wherein the detecting is performed as a function of:
• the first plurality of channel impulse responses,
• the fourth plurality of channel impulse responses, and
• the third plurality of channel impulse responses or the second plurality of channel impulse responses;
• determining, by the control unit, an occupancy state of the at least one seat of the vehicle, wherein the occupancy state is specific to the first target, wherein the determining of the occupancy state is carried out as a function of the first target detection;
• and
• operating the vehicle by the control unit as a function of the occupancy state.
