Abstract
In a method and the arrangement for operating an electric seat heating apparatus of a vehicle, it is provided, with a view to optimizing the heat-up behavior, that the given heat-up time or temperature, respectively, being reached, the heating power is preset by a microprocessor as a function of a field of characteristic curves or tables stored in a non-volatile memory such that for seats that differ in size, upholstery, and surface quality, the optimally to be supplied heating power or heating time, respectively, is empirically detected as a function of the desired seat temperature on the surface of the seating face or the rear and is stored in the non-volatile memory in the form of curves or tables, that a curve or table is selected from the field of characteristic curves or tables, respectively, by the microprocessor as a function of a coding recorded by the microprocessor, of the respective seat to the heated, and that then the power supply to the respective seat to be actually heated takes place in accordance with the selected curves or table.
