Abstract:
A drive arrangement of a motor vehicle, comprising:a drive motor (2) having an output shaft (4) which is actuated by means of E-gas wherein a control apparatus evaluates a control signal from a load cell during non-shifting normal driving operations, wherein the control signal is decisive for controlling a motor load; a shifting gearbox (10) having an input shaft (8) which has a plurality of gear steps that can be set manually by the driver; a disconnection-type clutch (6) which can be activated manually by the driver and that operationally connects the input shaft (8) of the shift gearbox to the output shaft (4); a clutch status recognition apparatus (20) a rotational speed determining apparatus (22) for determining a rotational speed of the input shaft (8) of the shift gearbox (10) while the disconnection-type clutch (6) is opened for the purpose of a gear step change; and the control apparatus (16) which receives signals from the clutch status recognition apparatus (20) and the rotational speed determining apparatus (22) and which adjusts the rotational speed of the output shaft (4) of the drive motor to a desired rotational speed while the disconnection-type clutch (6) is open, which is dependent upon the rotational speed of the input shaft (8) of the shifting gearbox (10); wherein the recognition apparatus (20) distinguishes between the load directions of pull and push and the control apparatus adjusts the rotational speed of the output shaft of the drive motor so that the desired rotational speed of the output shaft of the drive motor is higher than the rotational speed (26) of the input shaft of the shift gear box by an offset amount (30) in the load direction of pull, and smaller than the rotational speed (26) of the input shaft of the shift gear box by an offset amount (30) in the load direction push, and so that when the disconnection-type clutch (6) is closed after the gear step change the same load direction applies as before the gear step change.
