Method and Device for Establishing a Trajectory for a Vehicle
First Claim
1. A method for establishing a trajectory for a vehicle, the method comprising the acts of:
- registering coordinates of objects using a sensor;
calculating an occupancy map or cost map on the basis of the registered coordinates, wherein the occupancy map or cost map is subdivided into cells and a cell value is assigned to each cell, which cell value describes a presence and/or a vicinity of an object;
calculating a cost space, which comprises a plurality of layers, wherein each layer is subdivided into cells and a cost value is assigned to each cell, wherein the cost values in the respective layers are calculated in each case for a specific orientation of the vehicle on the basis of the cell values; and
determining a trajectory for the vehicle that is as cost-effective as possible.

Abstract
A method and a device for establishing a trajectory for a vehicle is provided. The method includes the following steps: registering coordinates of objects using a sensor; calculating a cost map on the basis of the registered coordinates, wherein the cost map is subdivided into cells and a cost value is assigned to each cell, which cost value describes the presence and/or the vicinity of an object, calculating a cost space, which has a plurality of layers, wherein each layer is subdivided into cells and a cost value is assigned to each cell, wherein the cost values in the respective layers are calculated in each case for a specific orientation of the vehicle, and determining a trajectory that is as cost-effective as possible.

20. A device for establishing a trajectory for a vehicle, comprising:
-
a sensor; a computer, and an interface, wherein the computer has a stored computer program executed to; register coordinates of objects using a sensor; calculate an occupancy map or cost map on the basis of the registered coordinates, wherein the occupancy map or cost map is subdivided into cells and a cell value is assigned to each cell, which cell value describes a presence and/or a vicinity of an object; calculate a cost space, which comprises a plurality of layers, wherein each layer is subdivided into cells and a cost value is assigned to each cell, wherein the cost values in the respective layers are calculated in each case for a specific orientation of the vehicle on the basis of the cell values; and determine a trajectory for the vehicle that is as cost-effective as possible, wherein the trajectory with the lowest possible risk of collision is providable at the interface.
