Problems solved by technology

[0007] A disadvantage of the known lane change assistance systems is that they have to be operated by the driver in complex lane change situations with several necessary lane changes to be carried out one after the other.

Embodiment Construction

[0045] exist figure 1 shows an exemplary passenger car 1 moving in the direction of the arrow on a primary roadway 10 with an exemplary embodiment of a driver assistance system 12 integrated in the vehicle. The initial traffic lane 10 is, for example, a passing lane on a motorway with three lanes in each direction. The arrow shown also marks the lane center of roadway 10 in addition to the direction of travel.

[0046] The vehicle comprises a steering wheel 3 for manually steering the vehicle 1 and a blinker control lever 4 integrated in the steering column, in particular. The flashing light control lever 4 can be positioned in a neutral position, in one of two soft-press flashing positions for lane changes left or right, or in one of two locked continuous flashing positions left or right.

[0047] The operating electronics 2 serves to detect the position of the flasher control lever 4 , which transmits the position of the flasher control lever 4 to the driver assistance sys...

Abstract

The invention relates to a lane-change assistance system for a motor vehicle for the automated performance of a lane change with at least automated lateral guidance. The assistance system is designedto determine, on the basis of information from a navigation system for navigation, that a plurality of lane changes from the current lane to a target lane are required in order to follow the navigation. The driver assistance system is also designed to inform the driver of a need to change lanes. By means of a triggering operation action by the driver, the driver can indicate the driver wants to perform the required number of lane changes in order to follow the active navigation. The driver assistance system checks if such a triggering operation action by the driver for triggering the requiredplurality of lane changes exists. If it is determined that the triggering operation action by the driver exists, the required plurality of lane changes from the current lane to a target lane are performed in an automated manner by means of the lane-change assistance system with at least automated lateral guidance.

Description

technical field [0001] The invention relates to a lane change assistance system for a motor vehicle for carrying out lane changes with at least automated transverse guidance. It is preferably provided that, in addition to the transverse guidance, also the longitudinal guidance is carried out automatically by the system. Furthermore, the invention also relates to a corresponding lane change assistance method. Background technique [0002] In known lane change assistance systems with automatic lane change, the driver typically indicates the desire to change lanes by deliberate manipulation, and the vehicle then follows the path planned by the system with automatic lateral guidance and generally also automatic longitudinal guidance. Trajectories on adjacent lanes. In such lane change assist systems, the driver's desire to change lanes is typically signaled by actuating an operating element, for example a blinker lever for activating the direction indicators visible from the o...
