A sensor arrangement for capacitive detection of an object, including: an electrode arrangement having a heating element as an electrode; a detection device providing a detection signal to a sensor electrode and capacitively detecting the presence of an object near the sensor electrode; a high-side switch connected between a heating power source having a first potential and the heating element; a low-side switch connected between the heating element and a second potential; and a gate controller closing the high-side switch and low-side switch in a heating mode and opening the high-side switch and low-side switch in a detection mode. A decoupling MOSFET is connected between the high-side switch and heating element. The gate controller closes the MOSFET in the heating mode and opens the MOSFET in the detection mode. During the detection mode, the decoupling circuit provides a third potential at a first node between the high-side switch and MOSFET.

This disclosure describes vehicle climate control systems and methods for more intelligently controlling an occupant comfort level within a vehicle interior in a manner that minimizes energy usage of the vehicle. The climate control system may be automatically controlled in an economical mode (i.e., ECO mode) when certain vehicle conditions are met. For example, the decision to activate the ECO mode of the climate control system may be a function of one or more variables including, but not limited to, vehicle speed, vehicle speed differentials, ambient temperatures, temperature differentials, battery state of charge, predicted low battery state of charge, etc.

A method for air conditioning a vehicle seat that is occupied by a person and that comprises at least one seat ventilation system, wherein at least one humidity sensor is arranged in a seat part and/or a backrest part of the vehicle seat as an actual humidity value transmitter for the absolute air humidity within the cushion part of the at least one seat part and/or backrest part so that a target state of comfort for a person seated on the vehicle seat can be accomplished via a control and regulating device through engagement of the seat ventilation system, wherein the target state of comfort can be controlled to a specifiable target humidity limit value through variation of the air flow of the seat ventilation system as a function of at least one control algorithm that evaluates the detected actual measured humidity value.

The present invention relates to an electrothermal converter, which has at least one cold side and one warm side. Provision is made that all the components of the converter cope with the thermal loads appearing when the converter is operated and/or in particular maintains its mechanical stability.

A method of controlling occupant thermal comfort includes the steps of driving a temperature in a seating zone to a temperature set point (54), holding the temperature set point in the seating zone for a predetermined time (56), and regulating the temperature in the seating zone to a corrected temperature set point based upon an equivalent homogenous temperature relating to vehicle cabin conditions and occupant gender (58).

A softness adjusting device for a vehicle seat is arranged under the seat cover of the vehicle seat and includes a soft inflatable bag and a valve component arranged outside the soft inflatable bag. The valve component includes a throttle valve and a one-way check valve. The throttle valve is configured to block or communicate a gas in the soft inflatable bag from or with an external air source. The one-way check valve provides a flow direction from outside to inside and is configured to fill the soft inflatable bag with the external air source when the pressure of the external air source is greater than air pressure in the cavity of the soft inflatable bag. The soft inflatable bag is filled with at least one flexible filler.

Disclosed herein are a cold/warm headrest for a vehicle and a method of controlling operation thereof. It is possible to provide cold air to an occipital region, a head, and a face of a seated occupant, and to provide warmth to a neck and shoulders of the occupant, in which the trapezius muscles are located along with peripheral nerves.

The invention relates to a surface temperature-controlling device, in particular for use in vehicles, comprising a first air-distributing layer which has multiple air inlets extending through the first air-distributing layer and multiple air outlets extending through the first air-distributing layer, and a second air-distributing layer which fluidically connects air inlets and air outlets of the first air-distributing layer, wherein the air inlets are designed to introduce pre-heated or pre-cooled air into the second air-distributing layer, and the air outlets are designed to discharge air out of the second air-distributing layer.

An air conditioning device for a vehicle seat, the air conditioning device includes: at least one flow generator to generate an air flow; at least one air inlet opening fluidically connected to a flow inlet of the flow generator to draw in air to be temperature-controlled; at least one air outlet opening fluidically connected to a flow outlet of the flow generator to eject the temperature-controlled air; a temperature-control device configured to control a temperature of the air drawn in through the at least one air inlet opening prior to the air being ejected from the at least one air outlet opening; and a temperature sensor configured to detect a temperature of the air drawn into the at least one air inlet opening and to adapt a heating power of the temperature-control device to the detected temperature of the drawn-in air.
