Abstract

A method detects the driving situation with respect to the yaw behavior of the vehicle, in which a desired value of the vehicle yaw angle rate .mu..sub.des is derived in a computer unit from measured values (such as vehicle speed, steering wheel angle), and at least one sensor signal is supplied to the computer unit from which the actual value of the vehicle yaw angle rate .mu..sub.act is derived. The difference between the desired value of the yaw angle rate .mu..sub.des and the actual value of the yaw angle rate .mu..sub.act is formed in the computer unit. The actual value of the yaw angle rate .mu..sub.act is subtracted from the desired value of the yaw angle rate .mu..sub.des, and at least one output signal is generated in and emitted by the computer unit from this difference. The output signal represents the detected driving situation with respect to the yaw behavior of the vehicle. The magnitude of the time derivative of the difference is used to derive whether there is a tendency towards an increasingly critical driving situation.
