Method for reducing power of e.g. seat heating device of motor car, involves reducing power of electrically operated heating device when determined distance or determined duration reaches or falls below defined distance or defined duration
The method involves determining distance (delta s) or time duration (delta t) up to a stop point by a satellite-based navigation system (4), where the stop point is estimated by a route target estimator. Power of an electrically operated heating device (1) is reduced by a control unit (5), the heating device is deactivated, and charging power of an electrical energy storage unit of a motor car is increased when the determined distance or the determined time duration reaches or falls below a defined distance (delta sth) or a defined time duration (delta tth). The stop point is formed as a target point such as travel home, workstation, highway restaurant and shopping center in a travel route. An independent claim is also included for a device for adjusting power of a heating device of a motor car.
