Abstract
The invention relates to a transmission synchronisation method and a transmission synchronisation device for at least two transmission units (T1, T2). The synchronisation takes place in that in each case an output revolution speed (n1, n2) of an axle drive shaft arranged in a transmission (T1, T2) is adjusted by means of a first and second adjustment unit (ADU1, ADU2). The synchronisation of the first and second transmissions (T1, T2) takes place by a result value (cal_out) of an arithmetic logic unit (140) being conducted to the second adjustment unit (ADU2) arranged at the second transmission (T2), dependent on the first transmission (T1) and on the reference value (v_set) of a preselection unit (100).

A method of synchronizing a first transmissions and a second transmission, said method comprising the steps of:
- conducting a reference value (v_set) as an input value to a first adjustment unit (ADU1) of the first transmission (T1);
- adjusting the first transmission (T1) with the first adjustment unit (ADU1) to the reference value (v set);
- determining a controlled variable (con_out) from at least one first output value (pUHC1, n1, pHCmax1) of the first transmission (T1) and at least one second output value (pUHC2, n2, pHCmax2) of the second transmission (T2);
- mathematically linking the controlled variable (con_out) to the reference value (v_set);
- inputting a result value (cal_out) to a second adjustment unit (ADU2) of the second transmission (T2);
- and
- adjusting the second transmission (T2) with the second adjustment unit (ADU2) to the result value (cal_out).
A transmission synchronization device comprising:
- a first transmission and a second transmission (T1, T2), each transmission having an adjustment unit (ADU1, ADU2),
- an arithmetic logic unit (140), a preselection unit (100), and in each case with measuring units arranged in the transmissions (T1, T2), and with
- a control unit (110) which receives output values (n1, n2, pUHC1, pUHC2, pHCmax1, pHCmax2) determined by the measuring units,
- a reference value (v_set) from the preselection unit (100) conducted to the first transmission (T1), and the result value conducted to the second transmission (T2) calculated from the reference value (v_set) and from a controlled variable (con_out) determined by the control unit (110).
