Abstract
A process provides vehicle-air-conditioning-influencing outside temperature information for an outside-temperature-dependent air conditioning of a motor vehicle interior, in the case of which the outside temperature is sensed continuously and the air-conditioning-influencing outside temperature information is obtained from the pertaining sensor signal. During hold phases which are triggered when a defined starting condition occurs, the air-conditioning-influencing outside temperature information is held at its temperature value when the sensed outside temperature value rises or stays the same. The hold phase starting condition consists of the fact that the vehicle speed is lower than a definable speed threshold value and the temperature of the motor vehicle driving engine or of a coolant for the driving engine is higher than a definable engine temperature threshold value or coolant temperature threshold value.
