A vehicle steering wheel includes a first volume of phase change material and a second volume of phase change material spaced apart from the first volume of phase change material. The first volume of phase change material contains a greater mass of phase change material than the second volume of phase change material. A first wall forms a rim of the steering wheel. The first wall is in direct contact with both the first volume of phase change material and the second volume of phase change material, so as to facilitate heat transfer between the first volume of phase change material and the second volume of phase change material.

A climate control system for a vehicle includes an infrared sensor disposed within a passenger compartment of the vehicle. The infrared sensor is configured to receive infrared radiation from a skin surface of a vehicle occupant. The climate control system further includes a controller configured to receive a signal indicative of a detected temperature detected at the skin surface. In response to the detected temperature deviating from a baseline temperature, the controller is configured to automatically control an HVAC system to add conditioned air into the passenger compartment and to control a thermoelectric device configured to adjust a seat surface temperature.

A system is disclosed for incorporation into a refrigerated delivery vehicle, the system enabling efficient cooling of the refrigerated compartment of a vehicle to avoid unnecessary idling of the vehicle's engine.

A heater device has a heater body and a heater case. The heater body has a heat generating part generating heat and radiates the heat supplied from the heat generating part. The heater case is attached to an interior member provided in an interior and houses the heater body, such that an interior-side surface of the heater body is located on a back side of the interior member. The heater case is provided with a ventilation passage through which a space outside the heater case located on the back side of the interior member communicates with the interior-side surface of the heater body.

An air filter assembly includes a seat assembly, an air filter unit, and an electronic control unit. The seat assembly may include a seat base and/or a seat back. The air filter unit may be connected to the seat assembly. The electronic control unit may be configured to automatically control the air filter unit. The air filter assembly may include one or more sensors, and/or the electronic control unit may be configured to automatically control the air filter unit according to information from the one or more sensors. The one or more sensors may include a biometric sensor. The biometric sensor may be configured to detect a body odor of an occupant disposed on the seat assembly. The one or more sensors may include a position sensor. The electrical control unit may be configured to automatically control the air filter unit according to information from the position sensor.

A climate-controlled hand grip assembly that uses one or more air jets or air channels directed at a tangent to an outer surface of the hand grip assembly. The outer surface may be curved and the air flow path may bend with the curve to provide a film of conditioned air along the outer surface that spreads beyond the point of origin of the air flow path. An exemplary embodiment of a steering wheel device with a rim and spokes is disclosed wherein the outer surface of the rim, spokes or both can be enveloped with conditioned air using a Coanda Effect.

A user body temperature assistance system associated with an air conditioning device, may include air conditioning controller configured to control an operation of an air conditioning device configured for adjusting an interior air temperature of a vehicle and determine an operation stage of a temperature adjustment unit in the vehicle according to an operation-based signal of the air conditioning device; and a temperature adjustment controller, which is configured to control an operation of the temperature adjustment unit for assisting a user body temperature according to the operation stage determined by the air conditioning controller.

A knit includes a knitted fabric into which a ground yarn is knitted and a heater wire configured to be energized to generate heat to heat a vehicle member. The heater wire is inlaid into the knitted fabric by inlay stitch.

A heater is installed indoors and heated to a target temperature. The heater is controlled by a controller. The controller has a regular control module which heats the heater to reach the target temperature. In addition, the controller has a suppressive control module which heats the heater to a suppressed temperature lower than the target temperature by electric power suppressed so that surface moisture adhering on the surface of the heater is decreased. When an activation of the heater is ordered, the heater is heated by the suppressive control module, after that, the heater is heated by the regular control module. The surface moisture is decreased by the suppressed temperature. Therefore, generating rapid boiling and/or rapid evaporation of the surface moisture by the target temperature may be suppressed.

A heating system for a vehicle includes: a heater for non-contact heating that emits radiation heat by heat supplied from its heat generating part, which generates heat upon energization, to give warmth to an occupant in a state where a body of the occupant is not in contact with the heater; a heater for contact heating that generates heat upon energization to give warmth to the occupant in a state where the body of the occupant is in contact with the heater; and a control device that controls operations of the heater for contact heating and the heater for non-contact heating. The control device adjusts a heating output provided by the heater for contact heating and a heating output provided by the heater for non-contact heating, and controls the operations. Therefore, the occupant can enjoy a sense of heating that is not stereotypical, and achieve energy saving.
