Abstract: Method for operating a driver assistance system of a motor vehicle having a combined longitudinal and transverse guidance function, wherein, starting from the combined operation of the longitudinal and transverse guidance function, the longitudinal guidance function is disconnected in response to the presence of at least one determined first disconnection condition, whereas the transverse guidance function is maintained.

Abstract: A method for operating a longitudinal driver assist system of an automobile, in particular an ACC system, wherein environmental data of the automobile are evaluated with respect to travel in a longitudinal convoy with at least three automobiles which include the automobile and at least two additional automobiles, which are driving immediately behind one another and each have an active longitudinal driver assist system. A convoy value is formed, and at least one operating parameter of the driver assist system is adapted depending on the convoy value.
