Abstract: A vehicle control system with which different vehicle functions, such as a driving dynamics function and/or a component protection function, can be controlled, in which vehicle control system, in the case of onroad driving, an rpm-based vehicle speed determined by a wheel speed sensor forms a reference variable, on the basis of which the vehicle control system determines driving parameters and/or controls the vehicle function. The vehicle control system is assigned an evaluation unit which, in the presence of both offroad driving operation and a tire change signal, determines a GPS-based vehicle speed as a reference variable, on the basis of which the vehicle control system determines the driving operation parameters, such as an offroad tire diameter, and/or controls the vehicle functions.

Abstract: A method for operating a refrigerant circuit of a motor vehicle, with a compressor which, in a heating mode of the refrigerant circuit, conveys a refrigerant through a first condenser, by which an air flow is heated. The compressor conveys the refrigerant through a second condenser for further cooling.

To increase the heating power available at the first condenser, a further partial flow of the refrigerant is expanded by a second expansion member and supplied to a second evaporator. The refrigerant coming from the evaporators is supplied to a suction side of the compressor.

Abstract: A method of placing an emergency call from a vehicle, based on a determined area of the vehicle. First and second paths which differ from one another are set up proceeding from a present position of the vehicle using geodata relating to boundaries assigned to immediately adjacent areas which lie between said areas. The method checks a boundary intersected first by the first path and which boundary is intersected first by the second path. Based on both routes intersecting the same boundary, a new first and a new second paths are set up. Based on the boundaries that are intersected first by the two paths proceeding from the present position differing from one another, the area to which the boundaries are assigned is determined as being the area in which the vehicle is presently situated, and the emergency call is placed based on the determined area.
