A longitudinal driver assistance system is provided in a motor vehicle. A first detection system identifies a first event which, starting from an actual speed, leads to the specification of an increased target speed at a predefined location-dependent first moment in time, and for identifying a subsequent second event which, starting from the increased target speed, leads to the specification of a target speed that is reduced in relation thereto at a predefined location-dependent second moment in time. A second detection system identifies, in an anticipatory manner, a predefined deceleration potential starting from the increased target speed to the reduced target speed. A functional unit reduces the acceleration to the increased target speed if, otherwise, the subsequent deceleration to the reduced target speed with the predefined deceleration potential cannot be completed at the location-dependent moment in time of the second event.

Longitudinal driver assistance system in a motor vehicle

A method for overriding a driving mode in an automatic longitudinal guidance mode of a motor vehicle includes setting a longitudinal guidance mode in the motor vehicle, providing a target speed for a journey event in the longitudinal guidance mode, manually overriding the target speed when the journey event is driven through by the motor vehicle, and aborting of the longitudinal guidance mode if the target speed of the journey event cannot be achieved within a settable delay.

Override of route events in the automatic longitudinal guidance mode

A longitudinally guiding driver assistance system in a motor vehicle includes a detection system for detecting currently applying events and relevant events lying ahead, which require an adaptation of the permissible maximum speed, and a function unit which, when detecting a relevant event, while taking into account the location of the relevant event lying ahead, determines a location-dependent point in time, whose reaching causes the function unit to initiate an output of prompt information for permitting an automatic adaptation of the currently permissible maximum speed to a new permissible maximum speed. The function unit is designed, in the case of an activation of the longitudinally guiding driver assistance system, while taking into account a detected currently applying event, to initiate a first output of prompt information for permitting an automatic first setting of the currently applying permissible maximum speed as the new permissible maximum speed.
