1. A method comprising:

  • establishing a dynamic target temperature range for a seat of a vehicle having a seat heating unit installed therein, the dynamic target temperature range defined by an adjustable minimum and maximum target temperature;

    activating a seat heating mode of multiple predefined seat heating modes based on an interior climate of the vehicle;

    defining the minimum target temperature, the maximum target temperature, and a wavelength time limit according to the activated seat heating mode; and

    controlling the seat heating unit such that a temperature of the seat continuously oscillates with a waveform that is bounded in amplitude by the defined minimum target temperature and the defined maximum target temperature without overlapping tolerances of each of the defined minimum target temperature and the defined maximum target temperature, and bounded in wavelength by the wavelength time limit,wherein the dynamic target temperature range or the wavelength time limit at any one seat heating mode differs from that at another seat heating mode, andwherein at least one complete oscillation occurs in the activated seat heating mode.
