PROBLEM TO BE SOLVED: To make the power of a heating device for an automobile coincide with specified power.SOLUTION: The power is adapted to a specified power demanded under continuously-changing operating conditions by readjustment based on a comparison of a set value and an actual value. For this purpose, a total current passing through the heating device is measured, for example, by a Hall sensor, and the momentary power consumption (actual value) is determined by multiplication with a specified in-vehicle voltage. |
