Fig. 5 is a block diagram,

FIG. 6a is a block diagram,

Fig. 6b is a block diagram and

Fig. 7 is a block diagram.

Fig. 1 shows a schematic representation of a motor vehicle 99 having a drive unit 1, such as internal combustion engine or motor, a torque transmission system 2, such as clutch, a transmission 3 in the drive train. Furthermore, a differential 4 , output shafts 5 and wheels 6 driven by the output shafts are shown. The vehicle 99 also has a device 98 for controlling the automatically actuatable clutch 2 and / or the automatically actuated transmission 3 .

Speed sensors 97 , which detect the speeds of the wheels, can be arranged on the wheels. The speed sensors can also functionally belong to other electronic units, such as an anti-lock braking system (ABS). At least one vehicle speed and / or one transmission speed can be determined from at least one wheel speed by means of a control unit. Further sensors can be door contact sensors 28 and a throttle valve sensor 29 . Furthermore, an idle switch can be integrated in the accelerator pedal sensor (load lever sensor), which indicates that the accelerator pedal is not actuated.

The drive unit 1 can also be designed as a hybrid drive with, for example, an electric motor, a flywheel with a freewheel and an internal combustion engine.

The torque transmission system 2 is designed as a friction clutch, such as a dry friction clutch or, in another exemplary embodiment, as a fluid, such as oil, a wet friction clutch, the torque transmission system also being able to be designed, for example, as a magnetic powder clutch, multi-plate clutch or torque converter with a converter clutch or another clutch. The friction clutch can also be designed as a self-adjusting clutch that adjusts for wear.

Furthermore, a control unit 7 and a schematically shown actuator 8 can be seen . The control unit 7 can be designed as an integrated control unit which carries out the control or regulation of, for example, the torque transmission system and the transmission or the shifting of the transmission stages. Furthermore, the engine electronics can also be integrated in the control unit. It is also possible that the control unit of the torque transmission system, transmission and / or motor are arranged separately and communicate with one another via data or signal lines. The control unit 7 is equipped with a computer unit in order to be able to process, store and forward the incoming signals and system variables. The control unit also generates control variables and / or signals for controlling the actuators for actuation.

In one embodiment, the transmission can have a transmission Traction power interruption when shifting or changing gears. In one  another embodiment, the transmission can be a transmission without Traction interruption when changing gears.

The torque transmission system 2 is mounted on or connected to a flywheel 2 a, the flywheel being a split flywheel with primary mass and secondary mass, with a damping device between the primary mass and the secondary mass, on which a starter ring gear 2 b is arranged. The clutch has a clutch disc 2 c with friction linings and a pressure plate 2 d and a clutch cover 2 e and a plate spring 2 f. The self-adjusting clutch additionally has means which allow adjustment and wear adjustment, a sensor, such as a force or displacement sensor, which detects a situation in which adjustment is necessary and can also be carried out upon detection.

The torque transmission system is actuated by means of a release mechanism 9 , such as, for example, pressure-medium-operated, such as hydraulic, central release mechanism, wherein the release mechanism can carry a release bearing 10 and the clutch is engaged and disengaged by means of actuation. However, the release mechanism can also be designed as a mechanical release mechanism, which actuates, acts upon or operates a release bearing or a comparable element.

The actuator 8 , such as the actuation unit, controls via a pressure medium line 11 or transmission path, such as hydraulic line, the pressure medium-operated, such as hydraulic, central release 9 for engaging or disengaging the clutch. The actuator 8 further actuates the transmission for switching with its at least one output element or with a plurality of output elements, for example a central switching shaft of the transmission being actuated by the output element or the output elements. The actuator thus actuates internal shift elements of the transmission for inserting, removing or changing gear stages or transmission stages, such as a central shift shaft or shift rods or other shift elements.

In one embodiment, the actuator 8 can be divided into at least two partial actuators, the one actuator for automated actuation of the clutch containing at least one drive and at least the second actuator containing at least one drive for automated actuation of the gear shift of the transmission. The actuators can be designed as a structural unit or can be arranged in separate housings. Furthermore, the control electronics can be arranged or integrated within the actuators or arranged within a separate housing.

The actuator 8 can also be configured or provided as a shift drum actuator which is arranged within the transmission. The shift drum actuates elements, such as shifting elements, which are guided in guides by means of a self-driven rotation, for shifting the gear stages. Furthermore, the actuator for switching the gear stages can also include the actuator for actuating the torque transmission system, in which case an operative connection to the clutch release device is necessary.

The control unit 7 is connected via the signal connection 12 to the actuator, so that control signals and / or sensor signals or operating status signals can be exchanged, forwarded or queried. Signal connections 13 and 14 are also available, via which the control unit is at least temporarily in signal connection with further sensors or electronic units. Such other electronic units can be, for example, the engine electronics, anti-lock braking system electronics or anti-slip control electronics. Other sensors can be sensors that generally characterize or detect the operating state of the vehicle, such as, for example, engine or wheel speed sensors, throttle position sensors, accelerator position sensors or other sensors. The signal connection 15 establishes a connection to a data bus, such as a CAN bus, via which system data of the vehicle or other electronic units can be made available, since the electronic units are generally networked with one another by computer units.

An automated transmission can be switched in this way or one Learn gear changes that this is initiated by the driver of the vehicle, by using a switch or a Gear selector gives a signal to shift up or down. A signal to select the next one could also be inserted Ganges are given. Accordingly, a electronic shift lever a signal can be provided in which gear the transmission should shift.

In another transmission program, an automated actuation of the Gear can be selected so that the selection of the current gear in Dependence on the operating parameters is carried out and if necessary, a switching process is initiated automatically. A automated transmission can also, for example, by means of characteristic values, Characteristic curves or maps and on the basis of sensor signals change gear independently at certain predetermined points carry out without the driver having to change gear.  

Furthermore, a neutral position N can be set, for example, in which there is no drive connection between the transmission input and the transmission output. Furthermore, a parking position P can be selected in which a parking lock is implemented. This parking position can also be selected automatically if, for example, the ignition key 51 is removed from the ignition lock and the operating state of the vehicle allows this. For example, removing the ignition key at high speeds may be mentioned, in which case a parking lock should not be inserted automatically.

The gear selection unit 40 can thus be set to an area M, such as manual driver-side gear selection, an area D, such as automatic gear selection for driving operation, an area P, such as parking lock, and / or an area N, such as neutral position. Furthermore, manual switching can be initiated via switches or a lever, for example.

The vehicle is preferably equipped with an electronic accelerator pedal 23 or load lever, wherein the accelerator pedal 23 controls a sensor 24 , by means of which the engine electronics 20 controls or regulates, for example, the fuel supply, ignition timing, injection time or the throttle valve position via the signal line 21 of the engine 1 . The electronic accelerator pedal 23 with sensor 24 is connected via signal line 25 to engine electronics 20 . The motor electronics 20 is in signal connection with the control unit 7 via the signal line 22 . Furthermore, transmission control electronics 30 can also be in signal connection with units 7 and 20 . An electromotive throttle valve control is expedient for this purpose, the position of the throttle valve being controlled by means of the engine electronics. In such systems, a direct mechanical connection to the accelerator pedal is no longer necessary or expedient.

The vehicle also has an engine starting device 50 which, based on a driver's engine attempt to start, actuates engine electronics and a starter for starting and / or starting the engine, for example by actuating the ignition key 51 in the ignition lock. However, a start process can only be initiated if there is a start authorization. If the start is enabled, the starter can be activated and energized. If there is no start enable, an electrical or electronic measure can be taken to prevent the starter from starting the engine. For example, a relay can be blocked or the power supply to the starter can be interrupted by electronics. For example, the control unit can set a start enable bit, which is queried when a start attempt is to be carried out.

FIG. 2 shows a diagram to illustrate a sequence for use within the vehicle, an engine start attempt being initiated by the driver at block 100, for example by means of an ignition key actuation. In block 101 , the position of the gear selector element 40 in position P, that is, whether the gear is in the park position, is queried. It is also expedient if the transmission state is queried and it is determined whether state P is present. In block 102 , a query is made as to whether a foot brake is actuated by the driver. It can also be queried whether a parking brake, such as a handbrake, or a service brake is applied. This can be queried via the brake light, for example. If a brake is actuated in block 102 and the query is answered in the affirmative, the control unit controls the torque transmission system in block 103 and disengages the clutch. In block 104 , the starter enable or engine start enable is issued and the engine is started using a starter. If the brake is not applied in block 102 , the process continues with block 100 and a starter release is not initially granted.

FIG. 3 shows a further exemplary embodiment to illustrate a sequence for use within the vehicle, an engine start attempt being initiated by the driver at block 150 . In block 151 , the position of the gear selector element 40 in position P is queried. It is also expedient if the transmission state is queried and it is determined whether state P is present. In block 152 , a brake, such as a parking brake, hand brake, or service brake, is actuated automatically. This can be achieved, for example, by the handbrake being applied automatically by an actuator such as an electric motor. This step 152 can also be omitted in a further exemplary embodiment. In block 153 , the control unit controls the element implementing a parking lock, such as the torque transmission system, and releases or unlocks the parking lock. For example, the clutch is disengaged. In block 104 , the starter enable or engine start enable is issued and the engine is started using a starter. The parking lock can be unlocked by automatically removing the gear engaged to implement the parking lock.

FIG. 4 shows another embodiment, where in block 200 for example by means of an ignition key, an engine start attempt. In block 201 , an inquiry is made or ascertained whether the transmission is in a neutral position N. In block 202, it is also queried whether a brake, such as the foot brake, is actuated. If this question is answered in the affirmative, a starter release or engine start release is issued in block 203 and the engine is started. If the brake is not applied in block 202 , the process continues with block 200 and no start release is given for the time being.

FIG. 5 shows a further exemplary embodiment, an engine start attempt being made in block 250, for example by means of an ignition key. In block 201 , a query is made or ascertained whether the transmission is in a driving position D (drive). This position can include an automated or driver-side control of the switching processes, with a driving gear, such as one of gears 1 to 5 or a reverse gear, usually being engaged. In addition, block 252 queries whether a brake, such as the foot brake, is actuated. If this question is answered in the affirmative, the torque transmission system is opened or disconnected in block 253 and a starter release or engine start release is given in block 254 and the engine is started. In block 255 , the clutch is closed again in such a way that the vehicle begins to crawl when a gear is engaged. If the query at 252 is answered in the negative, at least no start approval is given.

In a further embodiment of the invention, a neutral position in the transmission can also be engaged in block 253 before the engine is started. The gear can then be re-engaged with the clutch open.

Furthermore, it can be useful if further security aspects are taken into account and must be fulfilled as a necessary condition, before an engine start is enabled. For example, among these  Conditions. Queries regarding closed security contacts, such as Door contacts, bonnet contacts, seat contacts and / or belt contacts be. These contacts guarantee that no security issues Situation arises from unwanted openness.

Can be used as a vehicle standstill device or vehicle locking device for example, a braked component or a blockable unit For example, be provided within the transmission, the parking lock for example by a positive or frictional connection realized. The engine drag torque to the parking lock can Internal combustion engine can be exploited.

Fig. 6 shows in a block diagram 300 of an embodiment for control of the apparatus 98 according to the invention in the inventive automotive 99th At 301 , the device is turned on by an element such as the ignition key. Subsequently, the microprocessor of the control unit 7 is booted in block 302 , as started up, so that it is ready for operation. Then, in block 303 , a query is made as to whether a parking position or a driving gear is engaged within the transmission. If this is not the case and the neutral range is set in the transmission, the engine is switched to startable at block 304 , which can be done, for example, by a bit set in the control unit, whereupon the control unit communicates with the engine control via the data bus and the engine control unit at one the driver tries to start the engine by pressing the ignition key. In block 305 , the clutch is automatically disengaged. In one exemplary embodiment, a starting gear can then be engaged in block 306 , so that the vehicle can start when the accelerator pedal is subsequently actuated. If there is a parking position or a gear in the transmission, the clutch remains engaged in block 307 and the engine cannot be started in block 308 . All forward and reverse driving gears are considered as driving gears, in which a torque can be transmitted from the motor to the drive wheels in the inserted case.

FIG. 6b shows in a block diagram 310 an exemplary embodiment in a modification of the diagram 300 in FIG. 6a. Blocks 311 to 315 essentially correspond to blocks 301 to 305 .

In block 317 , the clutch is engaged with park position P or gear 1,. . ., 5 or 6 disengaged and / or a neutral area is automatically inserted in the transmission. The engine is then switched to startable in block 318 and / or a start enable is given so that the engine is started by the engine control system when the driver attempts to start. If necessary, a starting gear can then be engaged.

FIG. 7 shows a block diagram 400 for illustrating an exemplary embodiment of the use of the device according to the invention. At block 401 , the system, such as the ignition of the engine, is turned off. The control unit remains active. This takes place, for example, after the vehicle has ended its journey. A parking lock is then automatically engaged in block 402 by inserting a drive gear into the transmission. In block 403 , the clutch is automatically closed. The control unit then switches itself off automatically after a waiting time, for example.

In block 405 , the ignition of the vehicle and the control unit are switched on. At block 406 , the control unit microprocessor is booted. The transmission neutral position is queried in block 407 . If neutral N is engaged in the transmission, the engine can be started in block 408 and the clutch opens in block 409 . The engine is started when the driver attempts to start the engine. If there is no neutral gear in the transmission, clutch actuation is not carried out at 410 , i.e. disengagement of the clutch is prevented. In block 411 there is also no automated transmission actuation and the engine cannot be started in block 411 . Before starting, the neutral area must be inserted in the transmission.
