Abstract

Different applications of a humidity and/or temperature sensor integrated in a seat are presented. The humidity and temperature sensor signal represents sweat status of a person sitting on the seat. Applications are focused on regulating of active systems like climate seats in particular and vehicle HVAC systems, monitoring and visualizing of the gained data as well as processing data in systems.

Applications of Humidity and/or Temperature Sensor in a Seat

Abstract

Different applications of a humidity and/or temperature sensor integrated in a seat are presented. The humidity and temperature sensor signal represents sweat status of a person sitting on the seat. Applications are focused on regulating of active systems like climate seats in particular and vehicle HVAC systems, monitoring and visualizing of the gained data as well as processing data in systems.

Description

Vehicle seats constitute the biggest physical interface between occupant and the vehicle and therefore strongly influence the driving experience as well as driving comfort. State of the art high end vehicle seats are equipped with different actuators or systems to improve passengers comfort (e.g. ventilation, massage function, contour adaption).

Automated regulation of these systems towards maximal comfort requires additional information on the occupant's comfort status. A person's sweat rate as a psycho-physiological response can be used to assess his or her comfort level. The knowledge of the sweat and temperature status of a person thus opens new technical opportunities from regulating complex systems like vehicle climate seats and HVACs to visualization and logging of this information.

For humidity and/or temperature sensors different mounting positions are possible as well as the use of more than one sensor of each kind to calculate transfer rates or to notice local differences. Measured temperature and relative humidity data may be used in existing regulation systems (e.g. vehicles HVAC) as well as in new systems (e.g. stand-alone regulation of a climate seat). In addition, the sweat and temperature status can be added to a set of cardio-respiratory parameters collected with others sensors (e.g. implemented into steering wheel) for individual health monitoring.

Vehicle climate seats are in the main focus of the invention, however most use cases and regulation strategies can be transferred to other seat assemblies used in: e.g. Aircr...
