Driver assistance system for a two skew warning

It proposes a driver assistance system (1) for a two-wheeler. The driver assistance system (1) determines a limit value of a maximum to be taken by the two-wheel at a curve crossing angle, for example, considering a structural geometry of the two-wheeler or based on an observation of a driver-specific driving behavior. From a by means of a speed sensor (3) to be determined current speed of the bicycle as well as by means of a data source (5) to be determined, information about a course of a to be traversed by the bicycle ahead curve, the driver assistance system (1) can estimate the skew the two-wheeler will occupy in the curve ahead. the driver can be warned about a signal device (15) when the projected skew is larger than a critical angle physically or perceived by the driver as unpleasant skew. Alternatively, the driver assistance system (1) can be actively engaged via a control device (17) in the driving behavior of the two-wheeler.
