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.
A method for the standstill control of a drive body on which a friction force acts, a setting manipulated variable being determined and converted, utilizing an actuator, into a drive force acting on the drive body in order to bring the drive body to a standstill and/or to keep it at a standstill, wherein a setting manipulated variable is determined for the drive body to be brought to a standstill or for the drive body that has been brought to a standstill or for the drive body that is held at a standstill, which setting manipulated variable alone results in a drive force that does not overcome said friction force, wherein an activation manipulated variable is specified and the determined setting manipulated variable is changed by the activation manipulated variable to a relaxation manipulated variable, and wherein the relaxation manipulated variable is converted, utilizing the actuator, into a relaxation drive force acting on the drive body for moving the drive body, the activation manipulated variable being specified such that the relaxation drive force at least temporarily overcomes the friction force acting on the drive body during the standstill control.
A drive system comprising a movable drive body on which a friction force acts, wherein a control unit, which, in order to control the standstill of the drive body, is configured to determine a setting manipulated variable, and an actuator are provided, the actuator being configured to convert the determined setting manipulated variable into a drive force acting on the drive body in order to bring the drive body to a standstill and/or to keep it at a standstill, wherein the control unit is further configured to determine a setting manipulated variable for the drive body to be brought to a standstill or for the drive body that has been brought to a standstill or for the drive body that is held at a standstill, which setting manipulated variable alone results in a drive force that does not overcome said friction force, wherein the control unit is further configured to specify an activation manipulated variable and to change the determined setting manipulated variable utilizing the activation manipulated variable to a relaxation manipulated variable, and wherein the actuator is further configured to convert the relaxation manipulated variable into a relaxation drive force, acting on the drive body, for moving the drive body, the activation manipulated variable being specified such that the relaxation drive force at least temporarily overcomes the friction force acting on the drive body during the standstill control.
