Device and method for controlling the interior temperature of a motor vehicle
First Claim
1. A method for controlling an interior temperature in a motor vehicle, comprising the steps of:
- sensing an actual interior temperature with a radiation sensor and transmitting a signal representative of the internal temperature to a control device;
setting the interior temperature as a function of the measured temperature and a prescribed temperature; and
wherein the interior temperature is sensed with at least one radiation sensor arranged on a printed circuit board which carries the control device such that a sensitive surface of the radiation sensor detects thermal radiation which impinges on an outer surface of a housing enclosing the printed circuit board.

Abstract
A device and method for controlling the interior temperature in the passenger compartment of a motor vehicle, in which the actual interior temperature detected by a radiation sensor is fed to a control loop which sets the interior temperature as a function of the measured temperature and a prescribed temperature. In an arrangement for controlling the interior temperature in which the noise disturbance from the fan motor is eliminated and reliable control of the interior temperature is ensured nonetheless, the radiation sensor is arranged on a printed circuit board which carries the control loop, such that a sensitive surface of the radiation sensor detects the thermal radiation which impinges on an outer surface, facing the vehicle interior, of a housing enclosing the printed circuit board.
