Filter method for adjusting a computing load to a computing capacity of a vehicle-to-X communication system, wherein the vehicle-to-X communication system is used to receive and/or send vehicle-to-X messages, and wherein the received vehicle-to-X messages require processing by the vehicle-to-X communication system, wherein the filter method has two stages and decides which of the received vehicle-to-X messages are processed and which of the received vehicle-to-X messages are discarded, characterized in that a first stage of the filter method monitors variables over a relatively long time period and statistically analyses same over said relatively long time period and adjusts the filtering parameters over the long term, and a second stage of the filter method monitors the variables over a relatively short time period and statistically analyses same over said relatively short time period and adjusts the filtering parameters over the short term, wherein the filter method filters by the parameters receive field strength, type of vehicle-to-X message, data rate, data volume, time length, data encoding, sender position, packet rate and/or time-to-collision, and the filter method filters by the parameters according to the situation, wherein the following variables are taken into account in order to adjust the parameters: - processor load, - number of received data packets, - own speed of a receiver vehicle, - geographical data, e.g. from digital maps, - location information associated with learned amounts of data at the current location of the receiving vehicle-to-X communication system, and/or - information from surround sensors, from which the amount of data to be expected can be deduced. the filter method has two stages and decides which of the received vehicle-to-X messages are processed and which of the received vehicle-to-X messages are discarded, characterized in that a first stage of the filter method monitors variables over a relatively long time period and statistically analyses same over said relatively long time period and adjusts the filtering parameters over the long term, and a second stage of the filter method monitors the variables over a relatively short time period and statistically analyses same over said relatively short time period and adjusts the filtering parameters over the short term, wherein the filter method filters by the parameters receive field strength, type of vehicle-to-X message, data rate, data volume, time length, data encoding, sender position, packet rate and/or time-to-collision, and the filter method filters by the parameters according to the situation, wherein the following variables are taken into account in order to adjust the parameters: - processor load, - number of received data packets, - own speed of a receiver vehicle, - geographical data, e.g. from digital maps, - location information associated with learned amounts of data at the current location of the receiving vehicle-to-X communication system, and/or - information from surround sensors, from which the amount of data to be expected can be deduced. - processor load, - number of received data packets, - own speed of a receiver vehicle, - geographical data, e.g. from digital maps, - location information associated with learned amounts of data at the current location of the receiving vehicle-to-X communication system, and/or - information from surround sensors, from which the amount of data to be expected can be deduced.
