摘要： A multi-lane scenario driving support is provided for an ego vehicle in a traffic situation. Traffic surroundings are measured by an environment sensor system. The traffic surroundings include data about traffic and free space within an ego lane of the ego vehicle and an adjacent lane, and data about front proximity area and rear proximity area of the ego vehicle. A decision device evaluates the measured traffic surroundings and decides a driving operation to be executed by the ego vehicle based on at least one strategy. In the decision device, a cost function is used for choosing one of at least six strategies. The cost function is based on at least a core priority to avoid collision of the ego vehicle and not cause collision of the ego vehicle with a third party vehicle.

摘要： The present invention refers to a method for providing a multi-lane scenario driving support for an ego vehicle (10) in a traffic situation. Traffic surroundings are measured by an environment sensor system (14), whereby the traffic surroundings include data about traffic and free space within an ego lane (16) of the ego vehicle (10) and at least an adjacent lane (12a, 12b), and data about front proximity area (18) and rear proximity area (20) of the ego vehicle (10). A decision device (22) evaluates the measured traffic surroundings and decides a driving operation to be executed by the ego vehicle (10) based on at least one strategy. In the decision device (22) a cost function is used for choosing one of at least six strategies, the cost function being based on at least a core priority, whereby the core priority is to avoid collision of the ego vehicle (10) and not cause collision of the ego vehicle (10) with a third party vehicle (24. The decision device (22) by means of the cost function chooses one of at least the following six strategies: braking in the ego lane (16), to combine braking and steering within the ego lane (16) of the ego vehicle (10), steering within the ego lane (16) of the ego vehicle (10) to avoid an obstacle, to full-brake in the ego lane (16) of the ego vehicle (10), to combine braking and steering towards or when entering temporarily an adjacent lane (12a, 12b) and steering towards or when entering temporarily an adjacent lane (12a, 12b).
