Abstract

Disclosed is a method for identifying a critical braking operation of a two-track vehicle during cornering, which features the steps of detecting the running behaviour of a left-hand side wheel and of a right-hand side wheel, of comparing the running behaviour and/or of evaluating the time variation of at least one left-hand side wheel or right-hand side wheel, and of identifying a critical braking operation on the basis of the result of the comparison and/or of the result of the evaluation. As a reaction, there may ensue the reduction of the braking pressure of a wheel on the inside of the corner in response to identification. A device for identifying a critical braking operation of a two-track vehicle during cornering includes a detecting device (403a, b, 408a, b) for detecting the running behaviour of a left-hand side wheel and of a right-hand side wheel (301a-d), a first comparing device (409-412) for comparing the running behaviour and/or an evaluating device (404-407) for evaluating the time variation of at least one left-hand side wheel or one right-hand side wheel, and an identifying device (413) for identifying a critical braking operation on the basis of the output of the…
