A method for determining jumps and/or inflection points in an activation characteristic of an activation unit includes activating the activation unit using an activator, wherein different activation areas, separated from one another by the jumps and/or inflection points, are defined by the activation characteristic. Different activation forces for activating the activator are respectively set in the activation areas. The jumps and/or inflection points are determined by activating the activator by continuously determining activation travel values of the activator, respectively assigning an activation speed characteristic variable to the determined activation travel values, continuously forming value pairs from the determined activation travel value and the assigned activation speed characteristic variable, and checking, based on the value pairs which are formed whether significant changes occur in the activation speed. The jumps and/or inflection points in the activation characteristic are assigned to activation travel values at which significant changes occur in activation speed.
