Embodiment Construction
[0019] In the following description of the figures, identical elements or functions are provided with the same reference symbols.
[0020] figure 1 and figure 2 Two different cases are shown in which the method described below is implemented. figure 1 The situation of a two-lane right turn is shown, in which the ego vehicle 100 is driving in the left lane 1 of the two turning lanes 1 and 2, and another traffic participant (for example, another vehicle 200) is making the second turn. Driving on lane 2 , that is, on the right side of own vehicle 100 . figure 2 The situation of a right turn is shown in which the ego vehicle 100 is driving in the first turning lane 1 and another road participant (for example another vehicle 200) is in the second turning lane 2 to the right of the first turning lane 1 However, the second turning lane ends shortly before the first turning lane 1, so that the two vehicles 100 and 200 are not at risk of a collision. The method described below is...

Provided is a system for improving assistance systems for lateral vehicle movements in at least a two-lane turning process and a turning process, in which the adjacent lane ends before the turning of an ego-vehicle, comprising at least one electronic control unit, wherein the following method is carried out: consecutively or simultaneously, a future turning process of the ego-vehicle is determined, information relating to the lane markings and the number of carriageway lanes in the environment in front of and next to the ego-vehicle is detected, and it is determined whether at least one further traffic participant is in a relevant lane next to or behind the lane of the ego-vehicle. If this is the case, a future movement intention of the traffic participant is determined from the information relating to the lane markings and the number of carriageway lanes. And if it is determined that the ego-vehicle and the traffic participant are on an at least a two-lane turning lane, or that the traffic participant stops before the turning process of the ego-vehicle or leaves their lane, it is determined that there is no probability of a collision.
Description
technical field [0001] The invention relates to a device and a method for improving an assistance system for lateral vehicle movements. Background technique [0002] In vehicles there are various systems which are intended to relieve the driver during driving, for example in order to support the driver in certain situations. So-called assistance systems are used for this purpose, which can carry out a corresponding evaluation of signals and data based on the detection of the surroundings by means of sensor systems installed on the vehicle, but also by means of Car-to-X communication. Evaluation is carried out at the controller inside the vehicle or externally. Depending on the result of the evaluation and the configuration of the assistance system, for example, a warning sound is output which is to warn the driver in cornering situations, for example, of vehicles approaching from the side in order to prevent a collision. Further developed assistance systems can also interv...
