1. A module for evaluating a speed of a rear wheel (3G, 3D) of an automobile, wherein the module is fed by input parameters which comprise, as the only speed parameters, evaluations of speeds of the front wheels (2G, 2D) of the automobile, in that the speed of the rear wheel is evaluated by a formula, V
