 of this type have the advantage that pre-air conditioning is possible without emissions from an internal combustion engine or a fuel-powered heating unit, the pre-air conditioning is possible only for a limited time period on account of the storage capacities of the electric stores. As soon as the charging state lies or falls below a predefined limit value, pre-air conditioning is not possible (any longer), since otherwise the operation of the motor vehicle might be jeopardized. This leads to considerable comfort sacrifices for the driver.
EP 2 117 857 B1 has already disclosed a method for pre-air conditioning of a motor vehicle at a standstill by means of a heating and/or cooling unit which draws its energy from an electric store of the vehicle, it being possible for the heating and/or cooling unit to be operated at at least two performance levels. Here, when the heating and/or cooling unit of the parked vehicle is initially activated, the heating and/or cooling unit is initially operated at a first performance level with a low energy consumption, and is switched from the first performance level to the second performance level with a higher energy consumption only when a vehicle door is unlocked or opened.
It is an object of the invention to improve the abovementioned method with regard to the energy consumption, with optimum air conditioning of the vehicle being taken into consideration.
This object is achieved by way of a method and system of the independent. Advantageous developments arise from the dependent claims.
A basic concept of the invention is that in principle an excessive amount of energy must not be used in the case of pre-air conditioning at a standstill of the vehicle (and/or when the vehicle is locked and left), in which the energy for pre-air conditioning the vehicle interior is drawn from electric stores, in order for it to continue to be possible to ensure complete functional capability of the vehicle. If, however, only weakened interior preconditioning is performed, the customer loses a large part of the preconditioning effect as a result of one or more vehicle doors being opened. The interior very rapidly feels too warm or too cold on account of the surfaces being temperature controlled to too little an extent.
Based on this, the method according to the invention for preconditioning a heating and/or cooling unit in a motor vehicle at a standstill, in which the heating and/or cooling unit draws its energy for heating and/or cooling from an electric store, is in principle configured in such a way that, when the vehicle is at a standstill, the
of this type have the advantage that pre - air conditioning is possible without emissions from an inner burning engine or a fuel - powered heating system unit, the pre - air conditioning is potential only for a limited prison term menstruation on account of the storehouse capacities of the electric stores. equally soon as the charging state lies or falls below a predefined terminus ad quem value, pre - air conditioning is not possible (any longer), since otherwise the process of the motor vehicle might be jeopardized. This contribute to considerable comfort sacrifices for the driver.

Here, when the heating system and/or cool unit of the parked vehicle is initially activated, the heating and/or cooling unit is initially operated at a first operation degree with a low department of energy pulmonary tuberculosis, and is switched from the first performance level to the second operation level with a high energy consumption merely when a vehicle door is unlocked or opened.
