Motor vehicle gear device as well as method for control of a motor vehicle, and especially for the control of a gear device of a motor vehicle

A gear control unit for a motor vehicle device comprising:

• an electronic control unit and that has a memory;
• a computer unit;
• and,
• a device for transmitting and receiving signals, wherein said device for transmitting and receiving signals transmits signals to control a gear device;
• and,
• wherein, in the memory of said electronic control unit, there is stored a control program that, in cooperation with said computer unit and said device for sending and transmitting signals, controls the operation of a gear device of a motor vehicle, wherein said gear device is integrated into a power train of said motor vehicle that can be driven by an engine and is designed as multiple clutch gear.

A method for the control of a drive system of a motor vehicle, whereby said drive system comprises:

• a power train;
• an engine for driving said power train;
• a gear device with several wheel sets, wherein said gear device provides gears that can be engaged and disengaged, wherein said gear device has at least one torque transmission device, by means of which the power train or a particular power train branch can be released and locked;
• at least one drive shaft that is arranged on the side of the power train facing away from the engine and that can be driven by means of the engine via the power train;
• an electronic control unit;
• and,
• a device, such as a drive pedal, by means of which the desire to accelerate can be indicated, said method comprising:
• engaging said power train by means of the at least one torque transmission device to prevent or to shorten the thrust operating phases, when it is ascertained that the motor vehicle leaves a traction operation mode toward a thrust operation mode due to a desire to accelerate, and;
• releasing said at least one torque transmission device, wherein said electronic control unit, after said release of the at least one torque transmission device;
• and,
• before an acceleration desire is indicated, generating at least one signal indicating the rpm of an engine output shaft engaging an engaged torque transmission device on the side facing toward the engine is maintained greater than or equal to the rpm of a gear input shaft that engages in said engaged torque transmission device on the side facing away from the engine;
• and,
• ensuring, by means of the electronic control unit, that said gear input shaft is connected to said drive shaft via an engaged gear.
