    摘要: A method and a device for detecting critical driving conditions of a vehicle are provided, in which instantaneous values of a variable describing the transverse dynamics are measured, and a critical driving condition is detected by evaluating the time characteristic of the ascertained values. In order to detect a critical driving condition, a determination is made as to whether the ascertained values exceed an upper limiting value and, subsequently, fall below a lower limiting value, or whether the ascertained values fall below a lower limiting value and, subsequently, exceed an upper limiting value. Furthermore, a determination is also made as to whether the time interval between a first time point associated with the exceeding of the upper limiting value and a second time point associated with the falling below of the lower limiting value does not meet a specifiable time threshold value.
