Method and device for determining a vehicle position in a mapped environment
A method for determining a vehicle position of a vehicle to be located within a defined cruising range in a mapped environment is disclosed, wherein the vehicle position is determined by evaluating the position data of at least one predetermined component of the vehicle, and the position data are made available particularly by way of a plurality of position detecting sensors, which are fixedly arranged within the mapped environment.
1. A method for determining a position of a vehicle within a predetermined driving area in a mapped environment, comprising:
identifying the vehicle to the mapped environment;
obtaining positional data of at least one predetermined component of the vehicle with a sensor device fixedly arranged in the mapped environment;
determining the position of the vehicle by analyzing the positional data; and
navigating the vehicle through the mapped environment in a piloted manner.
2. The method of claim 1 , wherein the sensor device comprises a plurality of position detection sensors, wherein the method further comprises selecting one of the plurality of position detection sensors as a master sensor, which defines a global sensor coordinate system, and wherein the remaining ones of the plural position detection sensors describe their positional data in the global sensor coordinate system.
3. The method of claim 1 , wherein the predetermined component is a tire of the vehicle.
4. The method of claim 3 , wherein the positional data comprise positional data of four tires of the vehicle.
5. The method of claim 2 , further comprising monitoring and plausibilizing the positional data of each of the at least one predetermined component over time, thereby determining a position of each of the at least one predetermined component, and determining the position of the vehicle relative to the sensor coordinate system by fusing the positional data of each of the at least one predetermined component.
6. The method of claim 5 , wherein the positional data are analyzed in real time.
7. The method of claim 2 , wherein each of the plurality of position detection sensors has an opening angle of 180° and a range of up to 30 m.
8. The method of claim 2 , wherein each of the plurality of position detection sensors is a lidar sensor.
9. A device for determining a position of a vehicle within a predetermined driving area of a mapped environment, comprising:
means for identifying the vehicle to the mapped environment;
a sensor device fixedly arranged in the mapped environment and configured for providing positional data of at least one predetermined component of the vehicle; and
an analysis device for determining the vehicle position from the positional data,
wherein the vehicle is configured for being navigated through the mapped environment in a piloted manner.
