In order to specify a method for the standstill control of a drive body on which a friction force acts, by means of which a controlled reduction in undesirably stored potential energy is possible, an activation manipulated variable is specified which changes a setting manipulated variable which does not overcome the friction force to a relaxation manipulated variable, and the relaxation manipulated variable is converted by an actuator into a relaxation drive force acting on the drive body, wherein the activation manipulated variable is specified in such a way that the relaxation drive force overcomes the friction force, acting on the drive body, at least temporarily during the standstill control.
