• a first housing,
• wherein at least a first processor device of the assistance system is arranged in a first internal space of the first housing,
• wherein the first processor device generates heat at least in the operation;
• and
• a cooling device for cooling the first processor device,
• wherein the cooling device is formed on a first outer wall of the first housing,
• wherein a separate second housing with a second internal space is arranged stacked on the first housing viewed along a vertical direction of the electronic computing device,
• wherein at least a second processor device of the assistance system is arranged in the second internal space,
• wherein the second processor device generates heat at least in the operation,
• wherein the second housing is arranged on the cooling device at least in certain areas with a second outer wall opposing the first outer wall such that the cooling device is bounded by the first outer wall and the second outer wall at least in certain areas and is additionally formed for cooling the second processor device,
• wherein a columnar structure of the cooling device in a cooling area of the cooling device is formed on a first outer side of the first outer wall, and
• wherein a columnar second structure of the cooling device is formed on a second outer side of the second outer wall opposing the first outer side.
