Abstract

The invention relates to a method and a system for preconditioning a heating and/or cooling unit in a motor vehicle while the motor vehicle is at a standstill. The heating and/or cooling unit draws energy to heat and/or cool the vehicle interior from an electrical store. While the vehicle is at a standstill, the heating and/or cooling unit is activated in a first power stage in response to a signal of a remote starting device, and is then switched from the first power stage to a second power stage based on specified conditions. The first power stage may be designed such that the heating and/or cooling circuit is internally preconditioned to reach a specified target temperature by appropriately controlling the heating and/or cooling unit with the ventilation flaps at least nearly closed.
