  The invention is advantageous in particular in the

  measure o it avoids that in predefined systems

Above all, the invention makes it possible to avoid speed changes being carried out imprecisely due to expansions of the material, due to the temperature. According to a preferred embodiment of the invention, the gearbox device comprises a gear change lever or the like, which can be actuated manually to be brought into different positions. The output signals emitted by the control device are produced in particular by taking account of this position of the gearshift lever. Preferably the gear shift lever

  can be brought into the following switching positions

  : "blocking against a bearing", "reverse gear (R)", "neutral position (N)", "forward gear (D)", "manual gear change possible (M)", "so-called operation" steptronic "at higher speed (+)", "so-called" steptronic "operation at lower speed ()", "sporty driving", "economical driving" and

"driving in winter".

  Switching position "P" can be set

  particularly when storing the vehicle with the

  control sitive according to the invention and has the effect in particular of

  ment that a predetermined speed stage such as the first

  speed, is engaged. The switching stage "R" in particular makes it possible to reverse a vehicle using the control device. The switching position "N" has the particular effect that the gearbox device is brought into a neutral position or at zero speed. The shift position "D" has

  the effect in particular that a vehicle comprising the provision

  This is done with an order, preferably automa-

  infused. The "M" position of the gearshift lever has the particular effect that the gearshift lever is in a position, from which a gear

  The switching position "+" is especially intended for switching to a higher speed, and the switching position "-" is provided for switching to a lower speed step. The "sport driving" switching position acts in particular so that the control device produces output signals which

  have the effect that a motor vehicle comprising the

  positive control is conducted in a sporting manner

  tive. In particular, a motor vehicle is driven according to sporty driving when it is operated at a high rotation speed. Particularly in the case of

  high rotational speeds, an immediate speed stage

  upper part is engaged. The "eco-driving" position

  nomique "of the gearshift lever is in particular such that the driving of a motor vehicle comprising the control device is carried out while saving fuel. Already for fairly low speeds, a switching takes place on the stage of immediately higher speed. The "winter driving" position of the gearshift lever has the particular effect that

  the driving of the motor vehicle is adapted to temperatures

  In particular, it is also possible to provide

  separate mutators in particular in place of the "sporty driving" and / or "economical driving" and / or

  "driving in winter" of the gearshift lever.

  It is preferable in particular that in the "D" mode or in the "D" position of the gearshift lever, the vehicle can operate automatically in the mode

  of sporty driving or in the eco-driving mode

  mique. Preferably, the control device produces the output signals corresponding to a sporty driving characteristic or in accordance with an economical driving characteristic. The characteristic that the device

  selects to produce its output signals

  tie, depends in particular on the actuation of a

  fuel measurement. Preferably driving a vehicle

  Driving is done in sport mode when the fuel metering device, such as the accelerator pedal, is frequently actuated intensely, while the control device produces its

  signals according to an eco-driving characteristic

  appoints when it is established that the device for measuring the

  fuel is operated frequently only lightly.

  According to a preferred embodiment

  computational positive and / or a memory device and / or a

detection device.

  The detection device is in particular a device

in the control device.

  Preferably fields of characteristics, or

  characteristic curves or characteristic values

  ticks, which can be used to determine the energy input into a predetermined system or the temperature

  of a predetermined system, are stored in the device

memory.

  According to a particular embodiment

  The most preferred of the invention, the device for

  The temperature control device may use characteristic fields or characteristic curves or characteristic values for the calculation of the temperature or of the energy supply in a predetermined device or in a predetermined medium. These characteristic values can in particular be characteristic values of operation of this device or of a

  other device, which is present in the motor vehicle

  bile. A characteristic operating value is

  within the meaning of the invention in particular a characteristic value

  tick, which may vary during the operation of a vehicle

  automobile or its components, such as for example the gearbox device or the device

clutch.

  Preferably the control device or the device for determining the temperature uses an electric current or an electric voltage, such as for example an electric current or an electric voltage, which is applied to an electric motor, to determine the temperature and / or the energy supply. This electric current

  or this electrical voltage can be the current or the voltage

Preferably this characteristic operating value is the speed of

  motor rotation. In a particularly preferred way

  This characteristic operating value is the switching frequency of predetermined gear change processes, such as gear change processes in particular, which can be executed by the gearbox device or by the clutch device. It is particularly preferable that the

  characteristic value i.e. an average frequency of change

According to a preferred embodiment of the invention, the switching processes of the gearbox device and / or the clutch device can be performed in an automated manner by means of

  the use of switching characteristic curves.

  These switching characteristic curves indicate

  especially gear change points or ins-

  speed changes as a function of values

  predetermined operating characteristics of the vehicle

  automobile or at least one of these components.

  It is particularly preferable that these switching characteristic curves are modified

  under predetermined conditions, depending on the time

  temperature detected and / or depending on the energy supply

  determined, in a predetermined system. In a way

  Particularly preferable, modified switching characteristic curves or these modified switching characteristic curves are used to produce the

  control device output signals.

  Therefore, according to the invention, it is

  in particular possible that characteristic curves of

  mutation or switching instants depend on the temperature or the energy supply of systems or

  predetermined backgrounds. The characteristic curves of

  mutations are modified in particular so that the heat load of predetermined systems or the environment

predetermined is reduced.

  Particularly preferably, the number of switching processes which can be switched

  and / or switching processes initiated in the device

  positive forming the gearbox and / or in the clutch device is executed as a function of the temperature

  detected or depending on the determined energy supply. This modification is carried out in particular when the temperature

  temperature is greater than a predetermined temperature limit or that the energy supply is greater than a limit

of predetermined energy.

* Preferably an indication device is provided

  tor, which can be arranged so as to deliver in particular a visual or acoustic indication and which indicates to the driver of a motor vehicle equipped with a control device, under predetermined conditions, that the control device produces or will produce its

  output in accordance with a cooling characteristic

  or that we are in the presence of conditions which judiciously allow the output of the output signals in accordance with a cooling characteristic in order to

  prevent thermal overload, for example.

  In particular the display device indicates visually or acoustically that the control device produces output signals in accordance with a cooling characteristic when the temperature determining device indicates that the temperature

  in a predetermined system or in a location of a system

  energy or supply in this system or in a

  predetermined medium is higher than a predetermined temperature

  completed or at a predetermined energy limit.

  In accordance with a preferred embodiment of the invention, the controller can generate output signals in accordance with a cooling characteristic when an indicating device has indicated

  that the control device produces the signals

  ment to a cooling characteristic, and a predetermined return signal, which can be produced in particular by manual actuation of a system at the level of the indicating device, and is transmitted to the control device. This feedback signal can indicate to the control device

  that the output signals according to a characteristic

  cooling tick should be produced or should not

cannot be produced.

  The invention also provides in particular the possibility of

  that the driver of a motor vehicle has

  as long as a control device can accept or refuse

  the indication of the indicating device indicating that the device

  positive control plans to produce the signals of

  output in accordance with a cooling characteristic

  ment, since the temperature and / or the energy supply has exceeded a predetermined limit in predetermined areas. This improves the operating flexibility of the control device since there is an additional possibility of operator intervention.

  According to a particular embodiment

  The most preferred feature of the device is that the cooling characteristic, on the basis of which the controller produces the output signals under predetermined conditions, has the effect that the controller does not produce predetermined output signals for at least one interval. of predetermined time or up to

  the occurrence of a predetermined event, when the

  temperature determination indicator indicates that the

  temperature is higher than a pre-

  determined at a predetermined position or location and / or that the energy input in a predetermined system or in a predetermined environment is greater than a limit

of predetermined energy.

  In a particularly preferable manner, special functionalities of the control device are no longer realized or permitted for at least a predetermined time interval or in a manner controlled by an event, by the control device or by its output signals, under predetermined conditions, that is to say in particular when the thermal energy has exceeded a predetermined limit, by predetermined systems and / or in predetermined environments. For example a start is no longer possible in fourth gear or the clutch can no longer operate with sliding or an opening of the clutch is still only possible when another gear stage is engaged or the vehicle must be

arrested or the like.

  According to a preferred embodiment of the invention, the cooling characteristic is, under predetermined conditions, an emergency movement characteristic. This emergency movement characteristic has the effect in particular that only predetermined switching operations of the gearbox device and / or of the clutch device can

  be switched. This ensures that one can operate-

  drive the motor vehicle equipped with the

  order. In particular, according to the invention, only a driving or traveling program is executed.

  emergency, which may include a travel program

  emergency ment can also be used in other

  goals. In a particularly preferable manner a pro-

  gram of emergency displacement is executed in accordance with

  the cooling characteristic or the characteris-

  emergency displacement tick, this program essentially coincides with an emergency displacement program, which is triggered and implemented in the case of

  failure of predetermined sensors of a motor vehicle

  bile. The emergency displacement program is in particular a predetermined characteristic, on the basis of which

  the controller produces output signals.

  According to a preferred embodiment of the invention, the engine temperature or the cooling temperature or the energy supply in the engine or in the cooling water is determined, the control device controlling the box device speed in accordance with a cooling characteristic when the determined temperature is above a predetermined temperature limit or when the input

  energy is greater than a predetermined energy limit

  born. In accordance with this cooling characteristic

  preferably the switching frequency of the device

  tif forming the gearbox is increased, so that a greater number of switching processes can be executed during each unit of time. This increase in the switching frequency acts in particular so that the percentage of interruptions in the chain

  motor is increased and / or the percentage over time,

  in which the shift to a higher speed takes place, increases. This has the effect that the average engine speed decreases so that the engine runs

  at an operating point presenting a return

  more appropriate and therefore also more economical. The reduced percentage of energy loss due to improved efficiency reduces the engine temperature, so that overheating

  cooling water can be prevented.

  According to a preferred embodiment

  of the invention, the engine temperature and / or the temperature

  cooling water and / or energy supply

  in the engine or in the cooling water is deter-

  mined, in which case the engine speed is reduced when the temperature is above a predetermined temperature limit or when the energy supply is

  greater than a predetermined energy limit.

  It is particularly preferable that in the

  ment, that is to say in particular when the temperature of the cooling water is above a predetermined temperature limit, the speed of rotation of the engine is limited to a predetermined value, which can be variable and in particular can depend on temperature

  actual cooling water.

  According to a preferred embodiment of the invention, the travel program or the driving mode, with which the motor vehicle is driven, is modified under predetermined conditions when it is established that the temperature of the cooling water or the engine temperature or the energy input to the cooling water or the engine is higher than

a predetermined limit.

predetermined energy limit.

  In accordance with a preferred embodiment, an automatic changeover is made from manual mode to economical driving mode when it is established that the energy supply in the predetermined system or in the medium

  predetermined is greater than a predetermined energy intake-

  mined or the temperature is above a limit of

predetermined temperature.

  According to a particular embodiment

  The most preferred embodiment of the invention is that the engine speed or the average engine speed is reduced or the switching frequency is increased or a modified switching program is used when it is established that the engine temperature is in a predetermined range of high temperatures, which is

  especially above a predetermined limit temperature

  born, and / or that the engine speed and / or the engine torque are in a range, which allows the passage to a higher speed in accordance with predefined criteria.

  completed, and / or that a modification of the characteristic values

  predetermined conditions and / or that a vehicle has

  both an automated gearbox operates in an automated mode, that is to say in particular that the lever

  gear change is in position "D".

  Criteria for higher speed

  either engaged, can be a minimum driving comfort

  predetermined mum or economic criteria, such as a limit for fuel consumption or the like. A modification of the characteristic values of operating in displacement can be excluded in particular

for security reasons.

  According to a preferred embodiment of the invention, the control device delivers its output signals according to a cooling characteristic when the temperature of the clutch device or of a component of the clutch device has exceeded a limit of predetermined temperature and / or that the energy supply in this component or in the device

  clutch is greater than a predeter energy limit-

  mined, in which case the output signals from the control device act in particular so that the driving comfort in a vehicle and comprising a

command is altered.

  This poor driving comfort should not be

  technically conditioned, but can be pro-

  knowingly so as to attract the attention of the driver;

  high temperatures. In a particular way

  significantly preferable according to a characteristic

  predetermined emergency displacement, which can be used

  Also for example during other operating disturbances, such as the operating disturbance of a predetermined sensor or the like, the output signals from the control device are produced when it is established that a temperature of a clutch or a temperature of a component of the clutch device is higher than a predetermined temperature limit or when the energy supply in the clutch device or in

  the component is greater than a predeter energy limit-

undermined.

  Thanks to such an operating characteristic

  In particular, it is possible that a vehicle

  may still work, but predefined functionality

  travel ends cannot be implemented. The emergency movement characteristic can also be designed in particular so that the vehicle is subjected to jolts during movement so that

  that the driver is notified of the disruption of operation

  operation, in particular the increased temperature.

  a predetermined energy limit. The component of the provision

  clutch clutch can in particular be an electric motor,

  which actuates the clutch device.

  Preferably the cooling characteristic acts so that a limited number of switching processes in the gearbox device can be performed. In particular, the cooling characteristic preferably acts so that the

  Other features and advantages of the pre-

  after reference to the accompanying drawings, on the-

which:

  - Figure 1 shows a first form of realization

  sation by way of example of the invention, in the form of a schematic view in partial section; - Figure 2 shows a second embodiment taken by way of example of the invention, in the form of a schematic view in partial section; and

  - Figure 3 shows a progress of the pro-

  sold according to the invention by way of example, in the form

a schematic representation.

  Figure 1 shows schematically a vehicle

  cule 1 comprising a drive unit 2, such as for example an engine or an internal combustion engine. In addition, there is shown in the drive chain of the vehicle a torque transmission system 3 and a gearbox 4. In this exemplary embodiment, the torque transmission system 3 is arranged in the stroke flow between the engine and the gearbox, a driving torque of the engine being transmitted via the torque transmission system to the gearbox and from the gearbox 4, from the driven side, to a driving device 5 and to an axis 6 arranged in

downstream as well as to the wheels 6a.

  The torque transmission system 3 is arranged in the form of a clutch, such as for example a friction clutch, a disc clutch, a magnetic powder clutch or a direct clutch, the clutch possibly being a clutch. self-regulating or wear compensated clutch. The gearbox 4 is shown in the form of a manually controlled gearbox, such as for example a stepped gearbox. In accordance with the idea according to the invention, the gearbox can however also be an automated gearbox, which can be activated automatically using at least one actuator. As an automated gearbox, it should be understood in the following that it is an automated gearbox which is activated by means of an interruption in the flow of force and that the process of switching down the gear of the gearbox is executed in a controlled manner

by at least one actuator.

  In addition, a box can also be used.

  automatic gearbox, in which case the automatic gearbox

  matique is a gearbox essentially without

  interruption of the flow of force during the change process-

  speed and which generally consists of

planetary gear stages.

  In addition, a gradually adjustable gearbox can be used, such as a gearbox with a conical pulley winding. The box

  automatic gears can also be fitted with a sys-

  torque transmission stage 3, arranged on the driven side,

  such as a clutch or a friction clutch.

  The torque transmission system can also be equipped in the form of a starting clutch and / or a

  reversing clutch for reversing the direction of rotation

  tion and / or a safety clutch producing a torque which can be transmitted in a controlled manner in a targeted manner. The torque transmission system can be a dry friction clutch or a wet operation friction clutch, which for example operates in a fluid. It can also be a converter

of couple.

  The torque transmission system 3 has a drive side 7 and a driven side 8, and a torque is transmitted from the drive side 7 to the driven side 8 by the fact that the clutch pulley 3a is loaded by force by means of the pressure plate 3b, the Belleville spring 3c and the clutch release bearing 3e as well as by the 3d flywheel. For this load, the declutching lever 20 is actuated using an actuating device, such as

than an actuator.

  The torque transmission system 3 is controlled using a control unit 13, as

  control device, which may include the electro-

  control valve 13a and actuator 13b. In an other

  advantageous embodiment, the actuator and the system

  electronic control unit can also be available

  located in two different construction units, such

only boxes.

  The control unit 13 can contain the system

  control and power electronics used to control

  der the electric motor 12 and the actuator 13b. It is therefore possible, for example, advantageously to obtain the fact that a system requires as its only mounting space a space of

  mounting for actuator and electronic system.

  The actuator is constituted by a drive motor 12, such as an electric motor, the electric motor acting

  on a master cylinder 11 via a trans-

  mission, such as a worm gear or a straight pinion transmission or a crank transmission or a threaded spindle transmission. This action on the master cylinder can be done directly

  through a linkage.

  The movement of the output portion of the actuator, like the piston 11a of the master cylinder, is detected by a clutch displacement sensor 14, which detects the position or location or the speed or acceleration of a quantity, which is proportional to the position or the retracted position or to the speed or acceleration of the clutch. The master cylinder 11 is connected to the receiving cylinder 10 via a pressurized fluid line 9, such as a hydraulic line. The output element 10a of the receiving cylinder cooperates with the disengaging lever or the disengaging means 20, so that a displacement of the output part 10a of the

  receiving cylinder 10 has the effect that the means of desen-

  latching 20 is also moved or tilted so as to control the torque that can be transmitted by the clutch 3. The actuator 13b used to control the torque that can be transmitted from the torque transmission system 3 can be actuated by means of a fluid under pressure, i.e. it can be fitted with the master cylinder and the cylinder for receiving the pressurized fluid. The pressurized fluid may for example be a hydraulic fluid or a pneumatic fluid. It can be provided that the actuation of the master cylinder of the pressurized fluid is produced by an electric motor, the electric motor 12 being able to be controlled electronically. The drive element of the actuator 13b can be, apart from a drive element with an electric motor, also another drive element for example actuated by a

  fluid under pressure. In addition, action-

  magnetic sensors so as to adjust the position of an element

*is lying.

  In a friction clutch, the control of the torque that can be transmitted is achieved by the fact that the friction linings of the clutch disc between the flywheel 3d and the pressure plate 3b are tightened in a manner targeted. The loading of the pressure plate or friction linings by a force can be controlled in a targeted manner by means of the adjustment of the release means 20, such as for example the declutching fork or the central declutching stop, the pressure plate can be moved, adjusted and fixed at will between two end positions. A position

  end corresponding to a total clutch position

  Lely engaged and the other end position corresponds

  lays in a fully disengaged clutch position.

  For the control of a transmissible torque, which is

  for example less than the torque of the motor applied instantaneously

  temporarily, a position of the pressure plate 3b, which is located in an intermediate zone between the two end positions, can for example be controlled. The clutch can be fixed in this position using the targeted control of the declutching means 20. However, it is also possible to order couples of transmissible clutches, which are located in a defined manner beyond the torques motors present instantly. In such a case, the driving torques actually present can be transmitted, in which case the uniformities of the torque in the drive chain in the form, for example, of

  torque are amortized and / or isolated.

  For the activation, such as for example the command or the regulation, of the torque transmission system, sensors are also used which at least instants check the large quantities of the whole system and which supply the state quantities , signals and measured values, which are necessary for the control and which are processed by the control unit, a signal transmission link which can be provided and exist in the direction of other electronic units, such as for example an electronic system of the engine or an electronic unit with an anti-lock braking system (ABS) or a traction control system (ASE). The sensors detect for example rotational speeds, such as wheel rotational speeds, engine rotational speeds, the position of the load lever, the throttle position, the gear position engaged in the gearbox. , a gear change intention and others

  vehicle-specific characteristic quantities.

  FIG. 1 shows that a sensor 15 of the throttle valve and a sensor 16 of the speed of rotation of the engine are used, as well as a tachometer sensor 17 and that these

  sensors transmit measured values and information

  the control unit. The electronic unit, such as for example a computer unit, of the control unit 13a processes the input quantities of the system and transmits

  control signals to the actuator 13b.

  The gearbox is arranged in the form of a step or stage gearbox, the gear stages can be switched using a gear change lever or the gearbox being actuated or controlled by the using this gear shift lever. In addition, on the control lever, such as the gearshift lever 18, of the manually controlled gearbox, at least one sensor 19b is arranged, which detects the intention to shift gear and / or the

  speed position and transmits it to the

  order. The sensor 19a is articulated on the gearbox

  and detects the current speed position and / or an intensity

  gear change. The change identification

  Speed ment by means of the use of at least one of the two sensors 19a, 19b can be produced in such a way that the sensor is a force sensor, which detects the force acting on the speed change lever. However, the sensor can also be arranged in the form of a position displacement sensor, in which case the control unit identifies the intention to change speed on the basis of a variation in time of the signal.

of position.

  The control unit is connected at least temporarily.

  In fact, according to a signal transmission link, to all the sensors and evaluates the sensor signals and the system input quantities so that, depending on the current operating point, the control unit issues the instructions for control or regulation at least to one actuator. The drive element 12 of the actuator, such as an electric motor, receives from the control unit, which controls the actuation of the clutch, an adjustment variable as a function of measured values. and / or input quantities

  of the system and / or signals of the detection system

  rope. For this purpose, there is provided in the

  requests a control program in the form of a

  hardware and / or software, which assesses incoming signals

  and calculates or determines output quantities from comparisons and / or functions and / or fields

of characteristics.

  The control device advantageously comprises

  a torque determination unit, a torque determination unit

  speed position nation, a unit of determin-

  tion and / or a unit for determining the operating state or is connected, during a signal transmission, to at least one of these units. These units can be produced by means of control programs in the form of a hardware system and / or a software system so that the torque of the drive unit 2 of the vehicle 1, the speed position of the gearbox 4 as well as the slip, which is present in the torque transmission system, and the current operating condition of the vehicle can be

  determined using incoming signals from the sensors.

  The speed position determining unit determines the speed currently engaged, based on the signals from the sensors 19a and 19b. The sensors are articulated on the gear shift lever and / or on the internal adjustment means of the gearbox, such as for example a central gear shift shaft or a gear shift bar, and detect these elements, by example the position and / or the speed of these components. In addition, a sensor 31 can be arranged on the load lever 30 such as the accelerator pedal, which detects the position of the load lever. Another sensor 32 can function as an idle switch, that is to say that in the case where the accelerator pedal, such as the load lever, is actuated, this idle switch 32 is activated and , in the case where no signal is produced, it is deactivated so that on the basis of this digital information, it can be known whether the load lever, such as the accelerator pedal, is actuated. The load lever sensor 31 detects the

  degree of actuation of the load lever.

  Figure 1 shows, apart from the pedal

  accelerator 30, such as the load lever, and the

  connected to it, a brake actuating element 40 for actuating the service brake or the parking brake, such as the brake pedal, the handbrake lever or a parking brake actuating element , operated by hand or by foot. At least one sensor 1 is disposed on the actuating element 40 and controls the actuation of the latter. The sensor 41 is arranged by

  example in the form of a digital sensor, such as an in-

  switch, the latter detecting whether the actuating element is actuated or not. This sensor is connected

  on a signal transmission link, to a device

  tif of production of signals, such as stop lights, which signals that the brake is applied. This can be done for both the service brake and the parking brake. However, the sensor can also be arranged in the form of an analog sensor, in which case such a sensor, such as for example a potentiometer, determines the degree of actuation of the actuating element. Likewise

  this sensor can be connected according to a transmission link

  signal, to a signal producing device.

  FIG. 2 schematically represents a drive chain of a vehicle comprising a drive unit, a torque transmission system 102, a gearbox 103, a differential 104 as well as driving axles 109 and wheels 106. The transmission system torque transmission 102 is mounted or fixed on a flywheel 102a,

  this flywheel generally carrying a toothed starting crown

  reur 102b. The torque transmission system includes a pressure plate 102d, a clutch cover 102e, a

  Belleville spring 102f and a clutch disc 102c com-

  bearing friction linings. The clutch disc

  102c is also arranged with a cushioning device.

  between the clutch disc 102d and the flywheel

  tie 102a. An energy accumulator, such as a Bel-

  leville 102f, loads the pressure plate in the direction

  tion in the direction of the clutch disc, in which case a clutch release bearing 109, such as for example a stop

  clutch release center actuated by a fluid under pressure

  is intended for the actuation of the transmission system

  couple mission. A bearing or a clutch release bearing 110 is disposed between the central clutch release bearing and the tongues of the Belleville spring 102f. Thanks to an axial offset of the clutch release bearing, the Belleville spring is loaded and uncouples the clutch. The clutch can also be arranged in the form of a clutch actuated by

  compression or a clutch actuated in traction.

  The actuator 108 is an actuator of an automated gearbox, which also contains the unit

  actuation for the torque transmission system.

  The actuator 108 actuates switching elements internal to the gearbox, such as for example a gear shift shaft or gear shift rods or a central gear shift shaft of the

  gearbox, in which case under the effect of the action-

  In addition, the gears may be engaged in a sequential sequence or in any sequence, or may be engaged or disengaged, etc. Element 109

  clutch actuation is actuated through

  diary of the link 111. The control unit 107 is connected to the actuator via the link 112 for signal transmission, the links 113 to 115 of

  signal transmission being connected to the control unit

  command, in which case line 114 deals with back signals

  line 113 deals with control signals from

  from the control unit and the link 115 for example establishes a link with other electronic units by

  via a data transmission bus.

  To start or to start the vehicle essentially from a standstill or from a slow rolling movement, such as a ramping movement, i.e. to produce a targeted acceleration of the vehicle triggered on the driver's side, the driver essentially controls only the accelerator pedal, such as

  that the load lever 30, the automated actuation

  ordered or adjusted from the clutch controlling, by means of the actuator, the torque that can be transmitted from the

  torque transmission during a starting process.

  Under the effect of the actuation of the load lever, the support

  hate of a driver wanting a more or less intense or fast starting process is detected by means of the load lever sensor 31 and then the command is

  executed correspondingly by the control unit.

  The accelerator pedal and the sensor signals and the accelerator pedal are used as input variables for controlling the vehicle starting process. During a starting process, during starting, the torque that can be transmitted, such as the Mksoll clutch torque, is mainly determined by means of a function that can be fixed in advance or at

  using characteristic curves or character fields

  for example depending on the speed of rotation

  dependence on the rotational speed

  tion of the motor or other quantities, such as the motor torque, being advantageously achieved by means of a field

  characteristics or a characteristic curve.

  If, during a start-up process, essential-

  from stop or from a state of ram-

  page, in the case of a low speed, the load lever or the accelerator pedal is actuated to bring it to a determined value a, engine torque is controlled at

  by means of a motor control unit 40. The communication unit

  command of the automatic actuation system 13 of the clutch controls the torque which can be transmitted from the torque transmission system on the basis of functions

  or fields of characteristics which can be predetermined

  born so that a stationary equilibrium is established

  between the engine torque commanded and the clutch torque.

  The equilibrium state is characterized, depending on the posi-

  tion of the load lever, by a defined starting rotation speed, a starting torque or a driving torque as well as a defined torque which can be transmitted from the torque transmission system and a torque which can be transmitted to the drive wheels, such as for example the drive torque. The functional relationship of the couple of

  starting according to the starting rotation speed

  rabies will be referred to below as the characteristic curve

  start-up teristics. The position a of the load lever is proportional to the position of the throttle valve

engine.

  Figure 2 shows apart from the accelerator pedal 122, as a load lever, and a

  sensor 123 connected to this pedal, an action element 120-

  brake actuation 120 used to actuate the service brake or the parking brake, such as the pedal

  brake, handbrake lever or action element-

  hand or foot operated brake lock.

  At least one sensor 121 is arranged on the action element.

  120 and controls the actuation of this element. The

  sensor 121 is arranged for example in the form of a cap-

  digital sensor, such as a switch, the latter detects

  both the fact that the actuating element is actuated or not actuated. This sensor can be connected, via a signal transmission link, to a signal delivery device, such as a brake light, which indicates that the brake is applied. This can be done for both the service brake and the parking brake. The sensor can however also be arranged in the form of an analog sensor, in which case such a sensor, such as for example a potentiometer, determines the degree of actuation of the actuating element. Likewise, this sensor can be connected according to a signal transmission link, to a

  signal transmission device.

  FIG. 3 represents the appearance of an example of a method according to the invention. In step 300, a standard switching characteristic curve is predetermined, according to which the output signals of the control device can be produced for the execution of predetermined gear change processes in the gear device. During step 302, a check is carried out to know whether the speed of rotation and the engine torque are located in a predetermined zone, which allows in particular according to certain criteria, the passage to a speed

higher.

  If the engine speed or the torque is not located in this area, the

  standard characteristic curve is retained.

  But if the engine speed and the engine torque are mainly located in this zone, a check is made during step 304 to determine if

  the engaged speed stage meets pre-

  determined. In particular, it is checked here whether the speed stage engaged is a speed stage, during which speed change processes are triggered by a

automated way.

  Insofar as the engaged speed stage does not meet the predetermined conditions, the curve

  standard switching characteristic is retained.

  But insofar as the engaged speed stage satisfies the predetermined conditions, a check is carried out during step 306 to verify whether the temperature of the cooling water is greater than a predetermined temperature limit. If the water temperature of

  cooling is not greater than this time limit

  predetermined temperature, the standard characteristic curve

switching is retained.

  But if the temperature of the cooling water

  ment is higher than the predetermined temperature, during step 308 the characteristic curve is modified. Sub-

  additional polling programs can be run. The claims appended to the application are
