  • the FIG. 1 shows a schematic representation of a traffic situation 1 at an intersection 2 of two roads 11,12.
  • a vehicle 4 is shown at an intersection with traffic light circuit 3, which would like to turn left on a planned route 5 at the intersection 2.
  • a number of vehicles 6,7,8,9,10 the vehicle 4 so that the vehicle 4 can not turn immediately to the left.
  • Between the vehicles 6 to 10 are usually gap-related gaps available.
  • the first gap 13 and the second gap 14 are particularly marked.
  • the gap 13 is smaller in the distance between the vehicles 8 and 9 than the gap 14 between the vehicles 9 and 10.
  • a turning of the vehicle 4 is thus possible at the earliest using the gap 13, which could possibly lead to a turning operation at increased risk, because the gap 13 may be too small in extent.
  • the device according to the invention it is therefore particularly helpful if he is informed by the device according to the invention for driver information and assistance on the usually not yet recognizable gap 14 for him ,
  • the device according to the invention for driver information and assistance recognizes the traffic situation in the broader environment of the vehicle on the basis of sensor signals and at least signal-connected electronic units or systems and gives the driver a recommendation based on this data, as well as action assistance coupled with the connected assistance systems.
  • a recommendation may be made as to whether and when a suitably large gap will be encountered in oncoming traffic so that it may be used for turning left, such as gap 14 in FIG. 1 ,
  • a sufficiently large gap can also be identified on the lane intended for change, so that the lane change can be designed as safely as possible.
  • the recommendation for the driver can advantageously be made acoustically via a voice information output and / or optically via a display, wherein the output of the recommendation can be selected by the driver. He can thus select the means preferred by him and switch off less desirable means.
  • the FIG. 2 shows a schematic representation of a device according to the invention 100.
