The present invention relates to a method and apparatus for climate control in a motor vehicle. In a process for climate control in a motor vehicle, the motor vehicle is provided with an air conditioning device, and internal temperature of the motor vehicle is adjusted to a predetermined rated value though changes of at least one setup paratmeter of the air conditioning device. The at least one setup parameter is immediately set as an initial value stored in at least one characteristic curve of an engine after the engine of the motor vehicle is started, and, in a plurality of the different-value characteristic curves of the einge, at least one charasterustuc range of a present climatic condition is grouped to the initial values of the relates setup parameters.
