1. A method for evaluating driving situations, comprising:
- ascertaining and evaluating driving-state data, the driving-state data being evaluated and numerically represented with regard to risk potential for vehicle occupants, an overall risk potential being determined by at least one of ascertaining and estimating the current acting forces and the forces to be expected;
wherein the overall risk potential is modularly made up of a first partial risk potential and a second partial risk potential, the overall risk potential being calculated as an abstract numerical value in a range of 0 to 1;
wherein the first partial risk potential is the risk to an occupant as a result of the current forces and the first partial risk potential is determined from at least one of a first risk variable representing a transverse loading, a second risk variable representing a longitudinal loading, and a third risk variable representing a speed; and
wherein the second partial risk potential is an anticipated risk due to the forces to be expected, and the second partial risk potential is determined from at least one of a fourth risk variable representing a steering risk and a fifth risk variable representing a steering tendency.

Abstract
A method and a device for evaluating driving situations, where driving-state data are ascertained and evaluated. The driving-state data are evaluated and numerically represented with regard to their risk potential for vehicle occupants, an overall risk potential (total risk) being determined by ascertaining and/or estimating currently acting forces and/or forces to be expected and a movement of the occupant resulting from them.

8. A device for evaluating driving situations, comprising:
-
an evaluating and control unit adapted to receive driving-state data from at least one of an ESP control unit, an ABS control unit, and an airbag control unit, the evaluating and control unit further adapted to evaluate the driving state data with regard to a risk potential for vehicle occupants and to output it in the form of a numerical representation to a triggering unit for an occupant-protection system, the evaluating and control unit further adapted to determine an overall risk potential by at least one of ascertaining and calculating the current forces and the forces to be expected; wherein the overall risk potential is modularly made up of a first partial risk potential and a second partial risk potential, the overall risk potential being calculated as an abstract numerical value in a range of 0 to 1; wherein the first partial risk potential is the risk to an occupant as a result of the current forces and the first partial risk potential is determined from at least one of a first risk variable representing a transverse loading, a second risk variable representing a longitudinal loading, and a third risk variable representing a speed; and wherein the second partial risk potential is an anticipated risk due to the forces to be expected, and the second partial risk potential is determined from at least one of a fourth risk variable representing a steering risk and a fifth risk variable representing a steering tendency.
