METHOD AND DEVICE FOR SYNCHRONIZING A FIRST LOCAL ENVIRONMENT MAP WITH A SECOND LOCAL ENVIRONMENT MAP IN AN ENVIRONMENT OF A MOTOR VEHICLE

摘要

The invention relates to a method for synchronizing a first local environment map (9.1) with a second local environment map (9.2) in an environment of a motor vehicle (50), comprising the following steps: detecting first environment data of the environment of the motor vehicle (50) by a first Sensor system (2.1) of a first controller (3.1), detecting second environment data of the environment of the motor vehicle (50) by a second sensor system (2.2) of a second controller (3.2), providing the first local environment map (9.1) in the first controller (3.1 ) and the second local environment map (9.2) in the second controller (3.2), providing a first trajectory (11.1) in the first local environment map (9.1), providing a second trajectory (11.2) in the second local environment map (9.2), wherein the first trajectory (11.1) and the second trajectory (11.2) describe the same physical trajectory in the environment, determining a current position (14.1) of the forcefa in the first local environment map (9.1) by the first controller (3.1) by evaluating the first environment data, synchronizing the first local environment map (9.1) with the second local environment map (9.2), the synchronization comprising the steps of: determining a relative position (22) to the first trajectory (11.1) in the first local environment map (9.1) by the first controller (3.1), determining a further current position (14.2) of the motor vehicle (50) in the second local environment map (9.2) the second controller (3.2) by evaluating the relative position (22) with respect to the second trajectory (11.2). Furthermore, the invention relates to an associated device (1).
