Abstract

A method for the processing of sensor signals in a digital electronic system including a microprocessor, in which computed magnitudes are derived from the signals emitted by the sensors, and wherein the magnitudes are compared with one another to recognize certain travel situations. In order to carry out these comparisons simply and reliably using an economical microprocessor and cost-efficient sensors while applying simple computing steps, the comparison of two magnitudes derived from the sensor signals is carried out first on a level of the representation of one magnitude, for example, an angular yawing speed, and a second time on a level of the representation of the other magnitude, such as, for example, a steering angle. By this method, one comparison result supports the other. The method is advantageously used in a vehicle with a device for the control of travel stability, and preferably for the recognition of reverse travel.
