Lane change assistant for optimizing the traffic flow (traffic flow assistant)
First Claim
1. A traffic flow assistant for a vehicle, comprising:
- a surroundings sensor system configured to;
(i) recognize traffic-relevant objects on a traffic lane on which the vehicle is traveling and on at least one adjacent lane, and (ii) recognize specific presently existing gaps in the traffic surrounding the vehicle and determine vehicle-dynamic parameters of the objects, wherein specific future gaps in the traffic are predicted based on the vehicle-dynamic parameters; and
a control unit configured to;
(a) ascertain options for changing lanes, depending on the vehicle-dynamic state of the vehicle and at least one of;
i) the specific presently existing gaps in the traffic suitable for changing lanes, and ii) the predicted presence of specific future gaps in the traffic suitable for changing lanes, and (b) generate a signal for the lane selection, depending on the ascertained options for the lane change and a predefined optimization strategy;
wherein, on the basis of the signal, one of;
a lane selection is suggested to the driver autonomously;
or a driving maneuver is automatically initiated without action of the driver.

Abstract
A device for a traffic flow assistant for a vehicle includes a surroundings sensor system, which recognizes traffic-relevant objects on a traffic lane, on which the vehicle is traveling, and on at least one further adjacent lane, gaps in the traffic are recognized with the aid of the surroundings sensor system and vehicle-dynamic parameters of the objects are determined and future gaps in the flow of traffic are able to be predicted therefrom. For these recognized gaps and predicted gaps, lane change options are ascertained and, from this and the present and/or predicted presence of gaps in the traffic suitable for changing lanes and the vehicle-dynamic state of the vehicle, a signal for the lane selection is generated, which is dependent on the lane change options and an optimization strategy.
