A method for changing over transmission stages of a transmission arrangement , the transmission arrangement comprising: a first hydraulic machine coupled to a drive machine , a second hydraulic machine having an adjustable expulsion volume (VH), wherein the second hydraulic machine is fluidically connected to the first hydraulic machine via a first working line of the transmission arrangement and a second working line of the transmission arrangement , wherein the second hydraulic machine is coupled to a manual transmission of the transmission arrangement so that a torque of the second hydraulic machine can be transmitted to the manual transmission , the manual transmission having at least two transmission stages , the method comprising the following steps: a) requesting a changeover of an engaged transmission stage from a first transmission stage to a second transmission stage ; b) setting a setpoint value signal of the expulsion volume (VH) of the second hydraulic machine to zero; c) disengaging the first transmission stage , wherein before starting with said disengaging the first transmission stage the expulsion volume (VH) of the second hydraulic machine is already zero; d) regulating the second hydraulic machine so that expulsion volume (VH) of the second hydraulic machine reaches a value greater than zero, so as to bring a drag torque of the second hydraulic machine within a predetermined range; e) engaging the second transmission stage ; said steps a) to e) being executed sequentially. a first hydraulic machine coupled to a drive machine , a second hydraulic machine having an adjustable expulsion volume (VH), wherein the second hydraulic machine is fluidically connected to the first hydraulic machine via a first working line of the transmission arrangement and a second working line of the transmission arrangement , wherein the second hydraulic machine is coupled to a manual transmission of the transmission arrangement so that a torque of the second hydraulic machine can be transmitted to the manual transmission , the manual transmission having at least two transmission stages , the method comprising the following steps: a) requesting a changeover of an engaged transmission stage from a first transmission stage to a second transmission stage ; b) setting a setpoint value signal of the expulsion volume (VH) of the second hydraulic machine to zero; c) disengaging the first transmission stage , wherein before starting with said disengaging the first transmission stage the expulsion volume (VH) of the second hydraulic machine is already zero; d) regulating the second hydraulic machine so that expulsion volume (VH) of the second hydraulic machine reaches a value greater than zero, so as to bring a drag torque of the second hydraulic machine within a predetermined range; e) engaging the second transmission stage ; a) requesting a changeover of an engaged transmission stage from a first transmission stage to a second transmission stage ; b) setting a setpoint value signal of the expulsion volume (VH) of the second hydraulic machine to zero; c) disengaging the first transmission stage , wherein before starting with said disengaging the first transmission stage the expulsion volume (VH) of the second hydraulic machine is already zero; d) regulating the second hydraulic machine so that expulsion volume (VH) of the second hydraulic machine reaches a value greater than zero, so as to bring a drag torque of the second hydraulic machine within a predetermined range; e) engaging the second transmission stage ; said steps a) to e) being executed sequentially. <EOS>
