Vehicular cabin monitoring system

A vehicular cabin monitoring system, the vehicular cabin monitoring system comprising:

• a radar assembly disposed in a cabin of a vehicle equipped with the vehicular cabin monitoring system, the radar assembly operable to capture radar data;
• wherein the radar assembly is accommodated by an interior rearview mirror assembly of the vehicle;
• wherein the vehicular cabin monitoring system is electrically coupled to a vehicle communication bus of the vehicle;
• wherein the radar assembly comprises at least one radar transmit antenna that is operable to transmit radar waves;
• wherein the radar assembly comprises at least one radar receive antenna that is operable to receive radar waves;
• wherein the transmitted radar waves are transmitted at least to a hotspot zone in the cabin of the vehicle;
• a data processor operable to process radar data captured by the radar assembly;
• wherein the vehicular cabin monitoring system, via processing at the data processor of radar data captured by the radar assembly, determines presence within the hotspot zone of a body part of an occupant present in the cabin of the vehicle;
• and
• wherein, at least in part responsive to determining presence within the hotspot zone of the body part of the occupant, a window of the vehicle is opened.

A vehicular cabin monitoring system, the vehicular cabin monitoring system comprising:

• a radar assembly disposed in a cabin of a vehicle equipped with the vehicular cabin monitoring system, the radar assembly operable to capture radar data;
• wherein the radar assembly is accommodated by a mirror head of an interior rearview mirror assembly of the vehicle;
• wherein the radar assembly comprises at least one radar transmit antenna that is operable to transmit radar waves;
• wherein the at least one radar transmit antenna is operable to transmit frequency modulated continuous wave (FMCV) radar waves;
• wherein the radar assembly comprises at least one radar receive antenna that is operable to receive radar waves;
• wherein the transmitted radar waves are transmitted at least to a hotspot zone in the cabin of the vehicle;
• a data processor operable to process radar data captured by the radar assembly;
