Claim 5:
6. A method for controlling an automobile comprising a device for controlling braking of an automobile, the device comprising a module for evaluating a speed of a rear wheel (3G, 3D) of the 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, the speed of the rear wheel is evaluated by a formula, V
