A method for working out instruction cartography for a temperature at entry into a filter. The method determines for each combination, which includes a soot mass in a particle filter, a temperature at the filter output, an air flowrate through the filter and a soot combustion rate in the filter and is associated with a time t, a value assignable to the instruction, wherein the value is selected such that the filter output temperature remains less than a maximum permissible temperature after a pedal release at a time L.
