In a process and apparatus for controlling an interior temperature of a motor vehicle a nominal temperature is set and is used with a sensed interior space temperature to produce a difference value which is fed to a controller (R). The controller produces a controlling value from the difference value which it feeds to an output stage (E) for cyclically and directionally driving a DC motor (M) which adjusts the position of an adjustable member (SG) to influence an amount of heat fed to an interior space (I) of the motor vehicle. A position signal of the adjustable member is measured and fed in a control loop in order to ensure an exact and dependable positioning of the adjustable member, with the positioning signal being formed by measuring and analyzing partial movements of the DC motor through predetermined angles for activations and further rotation of the DC motor.
In a process for controlling interior-space temperature of a motor vehicle of a type in which a nominal temperature is preset and an interior space temperature is measured from which a difference value is formed and fed to a controller from which a regulation value is formed and fed to an output stage for cyclically and directionally driving a dc motor which adjusts the position of an adjustable member to influence an amount of heat fed to an interior space of the motor vehicle, with a position-signal of the adjustable member being measured and fed into a control loop, the improvement wherein:
