Definitions
- the invention relates to a heating system of a vehicle according to the preamble of claim 1.
- the waste heat from the internal combustion engine is usually used for heating systems that use convection to control the temperature of the entire interior of the vehicle.
- this option for heating the interior is no longer available, so alternative types of heating and heating systems must be used.
- heating systems that temper the interior of the vehicle using radiant heat are particularly suitable. With these heating systems, heat is generated specifically and locally at a specific location in the vehicle using thermal radiation (infrared radiation), i.e. heating the entire interior of the vehicle, as in the case of heating by convection, is no longer necessary.
- thermal radiation infrared radiation
- DE 102021 103 399 A1 discloses a method for automatically setting a locally felt temperature in a camping vehicle by radiant heating on the subject of heating the interior of vehicles.
- a large number of electric surface heaters are integrated into a large number of flat accessories in different areas of use inside the camping vehicle.
- the heating output of at least one of these electric surface heaters is regulated and/or controlled depending on the exact location of a person inside the camping vehicle.
- Planar accessories inside the camping vehicle include, in particular, laminates, ceiling coverings or wall coverings, pieces of furniture, doors or similar objects.
- US 11 363683 B2 provides systems and methods for radiation heating using PTC radiation fields.
- a radiant heating system for warming an occupant of an enclosed space includes panels for radiating heat into the enclosed space toward the occupant.
- a power supply supplies electrical power to the fields.
- a controller controls the electrical power delivered to the panels based on a temperature in the enclosed space and the positions of the panels in the enclosed space
- the DE 102019202 223 A1 relates to an arrangement for heating a vehicle interior, in particular a rail vehicle interior, in which infrared surface heaters are arranged in the interior to heat the vehicle interior.
- the infrared surface heaters are designed as integrated components of interior surfaces.
- the invention is based on the object of specifying a generic heating system for a vehicle with which the heating output for an occupant of the vehicle can be conveniently and individually adjusted.
- the interior of the vehicle is heated specifically by heat radiation with at least one surface heating element, which is preferably arranged in an interior component of the vehicle, i.e. which is integrated in the interior component of the vehicle or which is arranged on an interior component of the vehicle.
- at least one surface heating element is arranged in the vicinity of a vehicle seat, to which a specific temperature control area is assigned, i.e. the environment in a specific area around the seat can be heated or tempered with at least one surface heating element.
- Any surface of an interior component of the vehicle can be provided as a receiving surface for a surface heating element, for example the backrest of a front seat of the vehicle and/or on the door panel of a side door of the vehicle and/or the footwell of the vehicle and/or the instrument panel of the vehicle and/or the center console of the vehicle and/or the roof lining of the vehicle.
- These receiving surfaces for a surface heating element are preferably directed in the direction of a respective occupant of the vehicle.
- surface heating elements can be provided in the backrest part (seat back) of a front seat of the vehicle for the occupants in the rear of a vehicle.
- the current heating requirement is determined and, depending on this, the heating output of the surface heating elements assigned to this vehicle seat is specified.
- the heating output of the at least one surface heating element assigned to a vehicle seat with a temperature control area is specified by a control unit of the vehicle, through which the voltage and current intensity of the respective surface heating element corresponds to the current heating requirement of the respective occupant of the vehicle located on a vehicle seat with a temperature control area is regulated and/or controlled.
- a sensor unit preferably designed as an optical sensor unit or as a thermal sensor unit, is provided in the vehicle.
- an optical camera provided as an alternative to the thermal sensor unit or in addition to the thermal sensor unit as an optical image capture unit of an optical sensor unit for determining the current heating requirement of the vehicle occupant located on a vehicle seat with a temperature control area
- the distance between at least one body part of the vehicle seat located on this vehicle seat Occupants of the vehicle and the at least one surface heating element assigned to this vehicle seat are recorded and from this the current heating requirement of the occupant of the vehicle located on this vehicle seat is derived and in particular the current heating requirement of different body parts of the occupant of the vehicle located on a vehicle seat with a temperature control area is derived become.
- sensor units using measuring methods can also be provided for detecting the distance between the at least one body part of the occupant and the at least one surface heating element, in particular a combination of different such sensor units.
- a temperature control area 10 for the rear seat 4 and thus for individual heating of a specific area for the occupant 2 in the rear area 3 of the vehicle or for the occupant 2 located in the rear seat 4 of the vehicle, is on the backrest 6 of the front seat 7 of the vehicle a surface heating element 11 is provided, which is integrated, for example, in the backrest clamping part 12 in the backrest 6 of the front seat 5 of the vehicle.
- the distance from the surface heating element 11 to certain parts of the body of the occupant 2 located on the rear seat 4 of the vehicle is determined, for example, among other things, the distance 8, 9 from the surface heating element 11 to the legs 5 of the occupant 2 on a rear seat 4 of the vehicle.
- This determination of the distance 8, 9 from the surface heating element 11 to the legs 5 of the occupant 2 can be done, for example, by an optical camera, which is arranged, for example, in the area of the vehicle roof, for example integrated in the headliner of the vehicle, or in the area of the center console of the vehicle is arranged.
