A method for ascertaining following distances as a function of position by a control device. Measurement data of at least one trajectory along at least one route, having a multiplicity of measurement points including position data and distance data from vehicles that are ahead, are received, A group of test points along the route is distributed at pre-defined distances from one another. At each test point, an intersection line that is oriented transversely in relation to a course of the route is generated, Pairs of points corresponding to the intersection lines are ascertained from the multiplicity of measurement points. Based on the distance data, at least one following distance is allocated to the pairs of points corresponding to at least one intersection line. A control device, a computer program, and a machine-readable storage medium are also described.

Creation of following distance profiles

A method for recognizing an error in a sensor signal during operation of a fuel injector of an internal combustion engine. In the method, a switch valve of the fuel injector is activated with the aid of an activation signal, and the sensor signal is detected as a signal of a sensor, which is provided for the purpose of detecting characteristic operating points of the fuel injector, in a respectively predefined time window of the sensor signal, which includes a point in time of a characteristic operating point of the fuel injector. At least one property of the sensor signal is determined, which includes a signal level and/or a rise time. It is determined, based on the at least one property of the sensor signal, whether an error is present.

A method for selecting at least one connection pattern drivable by road users using a control device. Trajectory data are received from at least one area. On the basis of the received trajectory data, starting points and end points of drivable trajectories are determined. All the connection patterns between the starting points and the end points of the drivable trajectories are determined in the form of connecting lines. The determined connection patterns are filtered by at least one filter. Connection patterns remaining after filtering are compared with route profiles from the trajectory data. For each remaining connection pattern a number of route profiles which correspond to the connection pattern are counted. A connection pattern with the highest number of matching route profiles is selected. A control device, a computer program, and a machine-readable storage medium are also described.
