This map data is then used as the basis for short and medium-term route planning, but now also more and more as a starting point for controlling a driving or driving assistance function.
- the sensor data from the environmental sensors are viewed and evaluated in conjunction with the map data.
- Map data especially high-resolution map data, includes detailed information about the vehicle’s surroundings and can improve decision-making in autonomous or semi-autonomous vehicles. It may even be possible to carry out functions of a semi-autonomous or autonomous vehicle at least partially and/or temporarily solely based on map data, for example in order to to compensate for sensor failures. This requires a reliable and robust fusion of map data and sensor data, in particular with regard to determining the position of the vehicle in relation to the map data.

- the sensor data is received from at least one environment sensor, for example a radar, lidar, camera or ultrasonic sensor.
- the map data is received from a map database, which can either be arranged locally or connected via a data connection, in particular via a mobile data connection. Traffic signs are identified in the data from the environmental sensors. Traffic signs are read from the map data.

The direction in which the traffic sign is pointing is taken into account. The orientation is considered as additional information. A further improved results Reliability in assignment.
- the orientation can mostly be efficiently derived from both the data from the environment sensor and from the map data.
- An object in the surroundings of a vehicle can in particular be a vehicle, a cyclist, a pedestrian, an animal or a static object such as a car tire or a traffic sign etc. lying on the roadway.

It is also possible for device 14 or control device 16 to be integrated into environmental sensor 18 . In particular, the environment sensor 18 can be mounted on the vehicle 12 . However, it is also possible for the device 14, the control device 16 and/or the environmental sensor 18 to be implemented separately, for example integrated into a smartphone.

- the input interface 24 is connected to an environment sensor, such as a radar, lidar, camera or ultrasonic sensor. It goes without saying that the input interface can also be connected to a number of sensors and can already receive sensor data that has been preprocessed in a corresponding manner. In particular, a cloud of points or a camera recording can be received, for example.
- the map data can be received either from a local or from a remote database.
- Visible traffic signs are recognized in the evaluation unit 26 by analyzing the received sensor data.

- a vehicle-fixed coordinate system can be used to determine the positions of the visible traffic signs from the sensor data.
- a coordinate system of the map data can be used to read out the positions of the traffic signs contained therein.
- recognizing the traffic signs may also mean determining an alignment in the sense of an orientation in relation to the corresponding coordinate system. It is also possible that a class, ie a type of traffic sign in the sense of a meaning content, is determined based on the sensor data and read out from the map data. It is thus determined whether it is a stop sign, a give way sign, etc., for example.

- a behavior of an autonomous or semi-autonomous vehicle is planned in the advance planning unit 32 .
- Planning the behavior of an autonomous or semi-autonomous vehicle means, for example, determining a short-term route or making a decision regarding a braking, acceleration or evasive maneuver.
- the advance planning unit 32 is designed to extend a time horizon of this planning if the security parameter indicates a high level of reliability of the assignment. In this respect, the advance planning horizon is made dependent on the previously determined security parameters. The more reliable the correlation between sensor data and map data, the greater the time horizon for advance planning.
- the security parameter as a basis for merging the sensor data with map data in further time steps.
- the higher the safety parameter the more the map data can be used to plan the behavior of the autonomous or semi-autonomous vehicle.

- the right-hand side shows that the two traffic signs 20 in the vicinity of the vehicle 12 are recognized in the same way by evaluating the sensor data from the surroundings sensor will.
- the assignment unit 28 makes an assignment between the visible traffic signs and the previously known traffic signs.
- an iterative closest point algorithm can be used for this purpose, which generates corresponding rotation and translation matrices.
- a safety parameter can then be determined based on the assignment.

- On the right (above) the perception of the environment sensors of the vehicle 12 within the field of view 34 of the environment sensor is shown. It is then shown below that the vehicle 12 is clearly located at position 1, since there is a complete match between the traffic signs 20 recognized based on the sensor data and the traffic signs 20 read from the map data.
- the security parameter therefore indicates a high probability of an appropriate assignment.
- FIG. 6 shows a case in which, as indicated on the right in FIG.
- the corresponding map data of the same environment are shown on the left-hand side, according to which a total of six traffic signs 20 should be present. Since an appropriate assignment can nevertheless be made based on the orientation, position and class of the traffic signs, position 1 is again determined as the position of the vehicle.
- the security parameter indicates a high probability of an appropriate assignment.
- 7 shows a situation in which only a single traffic sign 20 is detected by the environment sensors on the vehicle 12 in the field of view 34 of the environment sensor. The comparison with the map data shown on the left side, which contains six traffic signs 20 in the corresponding area, then results in an ambiguity between positions 1, 2 and 3. There is a round traffic sign 20 on the right at all three positions the vehicle 12. In this respect, no reliable, accurate assignment can be made.
- the security parameter indicates a low probability of a correct assignment.

- the method comprises steps of receiving S10 sensor data and map data, recognizing S12 visible traffic signs, reading S14 known traffic signs, assigning S16 the visible traffic signs to the known traffic signs and determining S18 a safety parameter.
- the method can be implemented in particular in the form of software that is executed on a processor of a vehicle or a vehicle control unit. It goes without saying that the vehicle can also be implemented as a smartphone app.
