To determine the functional ability or the performance capacity of vehicle-to-environment communications, the channel usage of the ISM radio band in use is determined by comparing the channel time occupied by communication messages to the maximum channel time available for communication messages. A warning message is output if the occupied channel time exceeds a threshold value.

Abstract: A method and system for compensating for a time discrepancy. A first and a second vehicle-to-X communication system resort to an external time base. The first vehicle-to-X communication system determines a first internal time base from the external time base and the second vehicle-to-X communication system determines a second internal time base from the external time base. The first vehicle-to-X communication system sends vehicle-to-X data and the second vehicle-to-X communication system receives vehicle-to-X data. The vehicle-to-X data to be sent include a time stamp generated from the first internal time base and captured ambient sensor data include a first time stamp generated from the second internal time base. Alignment of the captured ambient sensor data with the received vehicle-to-X data is used to determine the time discrepancy between the first internal time base and the second internal time base and to compensate for it using a correction value.

Abstract: Using sensors of a first and second sensor type first and second sensor data are detected and items of information describing identical objects and/or object attributes are allocated to one another in the first and second sensor data. The first and second sensor data are encumbered by first and second ambiguities. Values of the second encumbering ambiguities are at least as great as values of the first encumbering ambiguities. A comparison of the first and second encumbering ambiguities of items of information describing identical objects and/or object attributes takes place. In the case of values of substantially the same size, the items of information describing identical objects and/or object attributes are allocated to one another in the first and second sensor data. In the case of values which are not of substantially the same size the items of information describing identical objects and/or object attributes are confirmed or discarded.

A lead message is received by the following vehicle and rejected by the following vehicle or confirmed with a follow message.

The first and second elements of coordination information are compared by the following vehicle. In the case of a matching comparison result, the autonomous tracking is performed corresponding to the first and second elements of coordination information and, in the case of a deviating comparison result, the autonomous tracking is ended.

The method is distinguished in that the environment data and/or the map data and/or the position data are continually merged with a situation depiction that is already present in the database to form a current situation depiction, and both the database and the situation depiction are fixed in location. The invention also relates to an appropriate system.
