PROBLEM TO BE SOLVED: To provide an electric auxiliary heating device capable of avoiding excess of the temperature of air to be heated with high reliability. SOLUTION: A temperature of delivered warm air is adjusted depending on a speed of the vehicle. This adjustment is preferably through out a stored characteristic field, and by the characteristic field, a plurality of vehicle parameters (for example, vehicle speed, release state of convertible top and external temperature) can be easily taken into consideration. The temperature of the intruded temperature can be also led from a temperature value already utilizable in the vehicle. Thus, the electric heating device with sufficient handling can be outstandingly easily attained. The heating device can be used locally in the vehicle, for example, a seat of the vehicle or a rear part of a cabin. Even if the operating condition of the automobile is dynamically varied, temperature variation of the heated air can be easily avoided with high reliability. COPYRIGHT: (C)2009,JPO&INPIT
