  The objects, methods and advantages of the invention set out above, as well as others, will be more apparent to those skilled in the art by referring

  to the description which follows taken in conjunction with the accompanying drawings in

  which: In Figure 1 shows in schematic form a first exemplary embodiment of the invention; In Figure 2 shows in schematic form a second exemplary embodiment of the invention; In Figure 3 shows an example of a characteristic slip curve which can be used in an embodiment according to the invention, In Figure 4 shows the relationship between a factor which is used according to the invention for the purpose of controlling the coupling torque, and the speed of rotation; FIG. 5 represents a first example of the layout of various quantities characteristic of the operation of a vehicle according to an exemplary embodiment of the invention; and FIG. 6 represents a second example of plotting of various quantities characteristic of the operation of a vehicle according to a

  example of embodiment of the invention.

  Figure 1 schematically shows a vehicle 1 provided with a drive unit 2, for example an engine or combustion engine. In the vehicle drive path is also shown a torque transmission system 3 and a gearbox arrangement 4. In this exemplary embodiment, the torque transmission system 3 is arranged in the torque flow between the engine and the gearbox so that a driving torque of the engine is transmitted via the transmission system. torque to the gearbox and, from the gearbox 4 on the output side of it

  to the output shaft 5 and to an axle 6 arranged downstream, as well as to the wheels 6a.

  The torque transmission system 3 is configured as a coupling, for example a friction coupling, a flap coupling, a magnetic powder coupling or as a converter bypass coupling, the coupling being able to be an automatic adjustment coupling, a coupling with wear compensation. The gearbox arrangement 4 comprises for example a manual change gearbox, for example a gearbox with change of gear ratios. According to the concept of the invention, the gearbox can however also be an automated speed change gearbox, which can be switched automatically using at least one actuator. By automated gearbox, it is necessary to understand in what follows an automated gearbox which is switched with interruption of the traction force and in which the process of switching the gear reduction is carried out so

  controlled using at least one actuator.

  It is also possible to use an automatic gearbox, the gear change processes being substantially without interruption of the traction force in an automatic gearbox and this gearbox being generally constituted by gear ratios with gearbox planetary wheel type. It is also possible to use a continuously adjustable gearbox, for example a cone winding gearbox. However, the configuration of the automatic transmission may also include a torque transmission system 3, for example a coupling or a friction coupling, arranged on the outlet side. The torque transmission system can also be configured as a starting coupling and / or reversing assembly coupling to reverse the direction of rotation and / or as a safety coupling with selectively adjustable transmissible torque. The torque transmission system can be a dry friction coupling or a wet friction coupling, which operates for example in

  a fluid. It can also be a torque converter.

  The torque transmission system 3 comprises a drive side 7 and an output side 8, a torque that can be transmitted from the drive side 7 to the output side 8 by the fact that the coupling disc 3a is stressed at force by means of the pressure plate 3b, the spring 3c with discs and the release stopper 3 as well as the flywheel 3d. The release lever 20 is actuated by means of an operating device, for example an actuator, to generate this

solicitation.

  The torque transmission system 3 is controlled using a control unit 13, for example a switching device which can include the control electronics 13a and the actuator 13b. According to another advantageous embodiment, the actuator and the control electronics can also be arranged in

  two different modular units, for example different casings.

  The control unit 13 can contain the control unit and the power unit for controlling the electric motor 12 of

  the actuator 13b. This then offers for example the advantage that the clutter-

  ment that the system requires is only the space required for the actuator with electronics. The actuator consists of a drive motor 12, for example an electric motor, which intervenes on a master cylinder 11 by means of a mechanism, for example a worm mechanism or a spur gear mechanism or a crankshaft mechanism or a threaded pin mechanism. This intervention on the master cylinder can be carried out directly or by

through rods.

  The displacement of the output portion of the actuator, for example of the master cylinder piston 11a, is detected by means of a coupling path sensor 14 which detects the position or location or the speed or acceleration of a quantity which is proportional to the position or position of engagement, or respectively of the speed or the acceleration of the coupling. The master cylinder 11 is connected to the slave cylinder 10 via a line 9 of pressurized medium or, in other words, of pressurized fluid, for example a hydraulic line. The output element 10a of the slave cylinder is functionally connected to the release lever or to the release means so that a displacement of the output part 10a of the slave cylinder 10 itself causes the displacement of the release means 20 in order to control the transmissible torque by

the coupling 3.

  The actuator 13b for controlling the transmissible torque of the torque transmission system 3 can be maneuverable by a pressurized fluid, that is to say it can be equipped with a master cylinder and a slave cylinder, pressure fluid. The pressure fluid may for example be a hydraulic fluid or a pneumatic fluid. The operation of the master cylinder of pressure fluid can be provided by motor

  electric, the control of the electric motor 12 being electronic.

  The drive element of the actuator 13b can be not only a drive element with an electric motor but also another drive element, for example operated by pressure fluid. It is also possible to use magnetic actuators to establish a

position of an element.

  -urn In the case of a friction coupling, the transmissible torque is controlled by the fact that the friction linings of the coupling disc are pressed between the flywheel 3d and the pressure plate 3b by targeted way. The force application of the pressure plate and of the friction linings respectively can be controlled in a targeted manner by the position of the release means 20, for example a release fork or a central release device, the pressure plate then being able to be moved between two end positions and be adjusted and fixed at will. The first end position corresponds to a fully engaged position of the coupling and the other end position to a fully released position of the coupling. To control a transmissible torque which is for example less than the motor torque existing at a given instant, it is for example possible to establish a position of the pressure plate 3b which is located in an intermediate zone between the two end of travel positions . The coupling can be fixed in this position using the targeted control of the release means 20. It is also possible to control other torques transmitted by the coupling, which are definitively greater than the existing driving torques at a given time. In such a case, the driving torques existing at the corresponding instant can be transmitted, the torque irregularities present in the form for example of torque peaks in the drive path.

being amortized and / or isolated.

  In order to control, for example adjust or regulate the torque transmission system, the invention also employs sensors which at least temporarily monitor the relevant quantities of the whole system and which send state quantities, signals and measured values which are necessary for control and which are processed by the control unit, the invention also providing a possible connection of signals with other electronic units, for example motor electronics

  or electronic anti-lock system (ABS) or anti-lock device

  skating (ASR). The sensors detect, for example, rotational speeds, for example the rotational speeds of the wheels, the rotational speeds of the engine, the position of the load lever, the position of the throttle valve, the position of the gear engaged in the gearbox. speeds, one

  switching intention and other specific quantities of the vehicle.

  Figure 1 indicates that the system uses a throttle sensor 15, an engine speed sensor 16 and a tachometer 17 and that measured values and information are communicated to the control device. The electronic unit, for example a computer unit or a computer unit, of the control unit 13a processes the input quantities of the system and sends

  control signals to the actuator 13b.

  The gearbox is for example made in the form of a gearbox which has several gear ratios, which can be changed using a shift lever, that is to say that the gearbox can be operated or implemented using this switching lever. In addition, a sensor 19b which detects the switching intention and / or the gear position which is engaged and transmits it to the control device can be arranged on the operating lever, for example the switching lever 18, of the gearbox. with manual gear change. The sensor 19a is articulated on the box and

  detects the current speed position and / or a switching intention.

  The detection of a switching intention can be carried out, using at least one of the two sensors 19a, 19b, by the fact that the sensor is a force sensor which detects the force which acts on the switching lever. However, the sensor can also be a path or position sensor, the control unit detecting a switching intention at

  from the variation of the position signal over time.

  The control device is in signal connection, at least temporarily, with all the sensors and evaluates the sensor signals and the input quantities of the system in such a way that the control unit sends, according to the point of current operation,

  control or regulation orders to at least the single actuator.

  The drive element 12 of the actuator, which is for example an electric motor, receives from the control unit which controls the operation of the coupling a regulating variable as a function of measured values and / or

* system input quantities and / or signals from the connected sensors.

  -to For this purpose, a control program is implemented as hardware and / or as software in the control device and evaluates the incoming signals and calculates or determines according to comparisons and / or functions and / or from characteristic fields the output quantities. In the control device 13 are preferably applied a torque determination unit, a speed position determination unit, a slip determination unit and / or an operating state determination unit, or this device is in signal connection with at least one of these units. These units can be implemented by means of a control program in the form of hardware and / or software, so that the torque of the drive unit 2 of the vehicle 1, the gear position of the gearbox gears as well as the slip existing in the area of the torque transmission system and the current operating state of the vehicle can be determined by means of the incoming signals from the sensors. The gearbox position determining unit determines the speed currently engaged by means of the signals from the sensors 19a and 19b. The sensors are then articulated on the switching lever and / or on adjustment means internal to the box, for example a switching shaft or central switching axis, and these sensors detect for example the position and / or the speed of these components. . A load lever sensor 31 can also be arranged on the load lever 30, for example the accelerator pedal, and detect the position of the load lever. Another sensor 32 can function as a dry run switch, i.e. this dry run switch 32 is engaged when the accelerator pedal as the load lever is actuated, and this switch is put out of service in the event of an absence of maneuver signal in order to obtain information

  numeric indicating whether the load lever, for example the accelerator pedal

  rator, is maneuvered. Load lever sensor 31 detects the magnitude

  of the operation of the load lever.

  Figure 1 shows in addition to the accelerator pedal 30, which serves as a load lever, and sensors which are in connection with it, a M operating element 40 for braking to actuate the service brake or the locking brake , for example a brake pedal, a hand brake lever or an operating element, operated by hand or by foot, of the locking brake. At least one sensor 41 is arranged on the operating element 40 and monitors the operation of the latter. The sensor 41 is for example made in the form of a digital sensor, for example a switch, which detects whether the operating element is or is not operated. A signal device, for example a brake warning light can be in signal connection with this sensor, and signal that the brake is applied. This can be done for both the service brake and the lock brake. However, the sensor can also be produced in the form of an analog sensor, which is for example a potentiometer, and which communicates the extent of the operation of the operation element. This sensor can also be in connection with signals with a device for

signage.

  Figure 2 schematically shows a drive path of a vehicle which comprises a drive unit 100, a torque transmission system 102, an arrangement 103 which comprises at least one gearbox, a differential 104, as well as driving axles 109 and driving wheels 106. The protection device 106a against excessive rotational speeds cooperates - as shown diagrammatically -

  arrow 106b - with vehicle components. The reference numeral 106a alternatively or in addition represents a device for determining a decrease in the speed of rotation of the wheels. The torque transmission system 102 is arranged or assembled on a flywheel 102a, which generally carries a starter ring 102b. The torque transmission system includes a pressure plate 102d, a coupling cover 102e, a spring 102f with discs and a disc

  102c coupling with friction linings. the coupling disc 102c

  ment, possibly with a damping device, is arranged between the coupling disc 102d and the flywheel 102a. A force accumulator, for example the disc spring 102f, biases the pressure plate in the axial direction on the coupling disc, and a release stop 109, for example a central release device operated by hydraulic fluid, is provided. to operate the torque transmission system. Between the central release device and the disc spring tabs of the disc spring 102f is arranged a release stop 110. Under the effect of an axial displacement of the release stop, the disc spring is biased and the mating is years

  cleared. The coupling can also be carried out in the form of a coupling-

  compression or tension coupling.

  The actuator 108 is an actuator of an automated gearbox which also contains the operating unit of the torque transmission system. The actuator 108 operates switching elements internal to the box, for example a switching drum or switching rods or a central switching shaft of the

  box, the invention providing that the operation of the gears makes it possible to engage

  expensive speeds, for example sequentially or in any desired sequence, or to quit these speeds. The operating element

  109 coupling is operated through the link 111.

  The control unit 107 is connected to the actuator by the signal link 112 and the signal links 113 to 115 are linked to the control unit in such a way that the link 114 processes incoming signals, the link 113 processes control signals from the control unit and link 115 establishes a link with other units

  electronic for example by means of a data bus.

  This control unit 107 can preferably also execute

  for example the following functions or control the characteristic values

  following ticks: traction control device and / or automatic speed regulator and / or coupling control and / or gearbox preset and / or gearbox modification and / or selection of traffic program and / or adaptive driver identification and / or traffic dynamics regulation and / or theft protection and / or display control and / or on-board diagnostic system and / or slope lock and / or start and stop strategy and / or filtering drive oscillations and / or distance regulation between vehicles and / or electrically controlled braking system and / or safety system and / or

warning system.

  To start or start the vehicle mainly from

  stopping or starting from a slow movement, for example extreme speed

  ment slow, that is to say to accelerate the vehicle in a targeted manner by a driver-induced effect, the driver essentially operates only the accelerator pedal, for example the load lever 30, the controlled automated maneuvering or regulated coupling controlling by means of the actuator the transmissible torque of the torque transmission system during a starting process. The operation of the load lever, detected by means of the load lever sensor 31 makes it possible, after one or more more or less strong or rapid start-up processes, to detect the driver's wish, and the control unit then controls the vehicle correspondingly. The accelerator pedal and the accelerator pedal signal sensors are used as

  input quantity to control the vehicle starting process.

  During a starting process, the transmissible torque, by

  example the coupling torque, designated by Mkso, in the figures, abbreviated-

  tion of the torque setpoint of the coupling, is determined during start-up by means of a previously definable function or using characteristic curves or characteristic fields, for example as a function of the speed of rotation of the motor, the relationship with the engine speed or other quantities, such as the engine torque, being advantageously achieved by means of a characteristic field or

of a characteristic curve.

  If the load lever or the accelerator pedal is operated to a determined value a during the starting process, essentially from a standstill or from an extremely slow speed state, at low speed, a motor torque is controlled by command 40 from

  engine. The control unit for the automated coupling 13

  controls the torque transmissible by the torque transmission system in a way which corresponds to previously definable functions or characteristic fields, so that a steady state of equilibrium is established between the commanded engine torque and the torque coupling. The equilibrium state is characterized as a function of the position a of the load lever by a defined rotational speed of running, a torque - running or engine as well as a defined transmissible torque of the torque transmission system and a torque transmitted to the driving wheels, for example a driving torque. The functional relationship between the starting torque and the starting rotation speed is called in the following the starting characteristic curve. Position a of the

  load is proportional to the position of the engine throttle valve.

  In addition to the gas pedal 122, which is the load lever, and a sensor 123 in connection therewith, FIG. 2 shows a brake operating element 120 for operating the service brake or the parking brake. blocking, for example a brake pedal, a handbrake lever or an operating element, actuated by hand or by foot, of the blocking brake lever. At least one sensor 121 is arranged on the operating element 120 and monitors its operation. The sensor 121 is for example made in the form of a digital sensor, for example a switch, which detects that the operating element is actuated or is not actuated. A signaling device, for example a brake indicator lamp, which signals that the brake is applied can be linked to this sensor. This

  can be performed for both the service brake and the lock brake.

  However, the sensor can also be produced in the form of an analog sensor, such a sensor which is for example a potentiometer communicating the extent of the operation of the operating element. This sensor can also be in connection with signals with a signaling device. Figure 3 shows the plot of the engine torque as a function of the

  engine speed or gearbox speed.

  FIG. 4 represents the plot 310 of a factor, here in particular of a fast start factor F which is used for example according to the invention for

calculate the engine torque.

  Note that varying the slope of the "Quick Start" characteristic curve allows the coupling to engage at higher speeds, possibly even while the wheels are spinning. Figure 5 shows an example of plotting of various operating characteristic quantities when starting a vehicle while the wheels are turning. FIG. 5 represents, as a function of time, the plot of the speed of rotation 320 of the motor, of the motor torque 340, of the angle 360 of the pedal in units of degrees and of the coupling torque in

Nm units.

  Figure 6 represents the characteristic values represented in the

  Figure 5 for an example of a quick start type start.

  The invention relates to a vehicle which includes a drive device, a drive axle and a gearbox device and which can perform in particular the following functions: traction control device, automatic cruise control, selection of traffic program, display control and on-board diagnostic system, as well as a

  method of operating a vehicle.
