ABSTRACT:
Method and arrangement for providing, in a vehicle ventilating and temperature-regulating system, automatic regulation of flaps for adjusting the temperature of and distributing ventilation air to the vehicle interior. In the system, a ventilation unit has at least one regulatable warm air flap for a heat exchanger mounted in the unit and at least one regulatable air distributor flap for distributing ventilation air to outlets opening out in the vehicle interior. The respective regulatory movements of the flaps are synchronized and made infinitely variable by means of servo means controlled by an electronic unit which receives signals from temperature transducers and, after comparison with signals representing actual and desired interior temperatures, transmits output signals to the servo means for regulating the relative settings of the flaps.
