Description

car

The invention includes an actuator and control unit such as a drive unit such as a motor, an automatic torque transmission system and a gearbox, an operation unit having a shift gear and a drive unit, which can be controlled by a control unit for operating the torque transmission system. A motor vehicle comprising a device for controlling an automatic torque transmission system, said control unit being arranged in signal connection with at least one sensor and operating engine electronics and / or engine starting devices, vehicle assemblies and starting the vehicle engine. It is possible to apply an electronic unit such as an operating part on the driver's side for hanging.

The present invention also relates to a method of operating an automotive interior device.

An automobile with an automatic torque transmission system is known from DE 19504847. In general, a motor vehicle includes an operating part in which a driver operates a motor vehicle assembly that can be formed as an ignition lock having an ignition key. The ignition key allows the motor vehicle assembly to be operated in a first ignition key position where current flows to the assembly. The ignition key also allows the engine starting device to be operated by a driver's attempt to start the engine, generally at another key position.

In vehicles of the above-mentioned types, including automatic torque transmission systems, if the engine of a car, such as an internal combustion engine, is started by the engine starting device when the intention is to operate the engine when the gear is connected to the gearbox or parked locked, safety An important problem can arise from When there is a willingness to start under the above conditions, the car can suddenly inadvertently move forward and backward.

The situation occurs according to the actual gear position, where the vehicle is parked with the clutch closed or the torque transmission system automatically closes the clutch after parking the vehicle. If the engine is started with the gear connected or the clutch closed, a sudden movement of the vehicle may occur.

It is an object of the present invention to provide a vehicle of the type described above which allows simple operation without having to consider safety greatly. It is also an object of the present invention to provide a motor vehicle which is simple, inexpensive in terms of cost, comfortable in ride, high in reliability, and improved in known systems.

The present invention is to provide a method for operating a vehicle interior device to ensure the safe operation of the vehicle.

This object is achieved according to the invention, in which, after operating the control unit by the driver, the control unit receives and processes sensor signals from a sensor that senses a neutral position connected to the gearbox, wherein the control unit comprises: When the gearbox is connected to the neutral position, the torque transmission system is disconnected, the starter disconnect signal is sent to the engine starter, and when it is not connected to the neutral position, the starter disconnect signal is not transmitted to the engine starter.

In addition, after the operator has operated the control unit, the control unit receives and processes sensor signals from sensors that detect that they are connected to the neutral position in the gearbox, which, when connected to the neutral position in the gearbox, disconnects the starter from the engine starter. When the signal is sent and not connected to the neutral position, the brake is automatically activated, the torque transmission system is automatically disconnected and the starter is disconnected to start the engine.

The control unit processes the sensor signal from a sensor that detects that the control unit has been connected to the neutral position in the gearbox after the operator has operated it.When the control unit is connected to the neutral position in the gearbox, the control unit disconnects the starter to start the engine. When the signal is sent and not connected to the neutral position, the torque transmission system is automatically controlled so that the set torque can be transmitted by the torque transmission system and no starter disconnection takes place to start the engine.

According to the invention, after the operator has operated the control unit, the control unit processes the sensor signal from a sensor that senses gearbox information, such as indicating whether it is in a neutral position in the gearbox, the neutral position in the gearbox. When connected to the control unit, the control unit checks the gearbox information provided by the sensor, asks whether the brakes are engaged, and if the above conditions are met, the starter is disconnected to start the engine and at least one of the above conditions is not met. If not, the car is made so that the starter is not removed.

An advantage of the present invention is that after operation by the operator of the control unit, the control unit checks and processes sensor signals from sensors that detect gearbox information, such as indicating whether they are in a neutral position in the gearbox, When there is no error and connected to the neutral position in the gearbox, the control unit asks if the brake is engaged when the starter is disconnected and is not connected to the neutral position in the gearbox. The car can be formed so that separation occurs.

After the operator has operated the control unit, the control unit checks and processes the sensor signal from the sensor that detects the gearbox information indicating whether it is connected to the neutral position in the gearbox, the sensor signal is error free and neutral in the gearbox. When connected to the position, the control unit causes the starter to disengage, and when the gearbox is not connected to the neutral position, it asks if the shift is intended, and if the shift is intended, the clutch is controlled and the starter disengage occurs.

The advantage of the present invention is that at least one sensor which senses the driver shift intention after the driver has operated the control unit sends a signal to the control unit and if there is a shift intention signal, it is connected to the neutral position in the gearbox by at least one sensor. If it is determined whether or not it is connected and in the neutral position, the starter disconnection occurs by the control unit.

If the operator starts the engine with the torque transmission system connected or disconnected after the operator has operated the control unit, the control unit detects the actual gearbox position and the starter disconnection when connected to the neutral position. The starter is not disconnected when it is made by the valve and is not connected to a neutral position.

After the operator has operated the control unit, the torque transmission system is connected or disconnected and the control unit senses the actual gearbox position, and the torque transmission system is maintained at its actual position and if there is operator's manipulation to start the engine. In this case, the control unit is queried by the control unit to determine whether it is connected to the neutral position in the gearbox, and when it is connected to the neutral position, the starter is disconnected by the control unit.

After the operator operates the control unit with the torque transmission system connected or disconnected, the control unit detects from the brake sensor whether brake operation is present and determines whether the brake operation is connected to the neutral position in the gearbox or not. When connected, the control unit disconnects the starter. This kind of brake sensor may be a switched brake light switch even if the brake is actuated and no action occurs. The sensor operates according to the set brake operation and generates a signal.

It is advantageous if the car engine is started when the starter is disconnected and the driver attempts to start the engine.

When not in the neutral position or when the drive gear is connected, the torque transmission system is disconnected, the brake is actuated, the value that indicates the accelerator pedal actuation by the driver when the engine is running is asked, and the brake actuation is stopped when the accelerator pedal is actuated. The torque transmission system is connected to start the car according to the set characteristics.

When not in the neutral position or when the drive gear is connected, the torque transmission system is disconnected, the brake is actuated, the value that indicates the accelerator pedal actuation by the driver when the engine is running is asked and the brake actuates when the accelerator pedal is not actuated. And the torque transmission system is connected to move the vehicle forward according to the set characteristic.

According to the invention, the controlled torque which can be transmitted by the torque transmission system has a set minimum moment. The controlled torque that can be transmitted by the torque transmission system is in the moment region between 1/2 and 1/10 of the nominal torque of the drive unit. The controlled torque that can be transmitted by the torque transmission system is in the moment region between 10 Nm and 100 Nm.

The control unit can also determine from the sensor signal provided by the sensor whether the gear information is correct or not.

If the sensor value is out of the specified range, the control unit determines from the sensor signal that the gear information is incorrect.

When using more than one sensor, the control unit can determine from the sensor signal that the gear information is incorrect if the sensor values deviate from a defined range of values or do not have a predetermined correlation to each other.

When the power supply of at least one sensor is below the reference value it is convenient because the gear information is evaluated as wrong by the control unit.

In addition, the starter is not removed by the control unit when it is not connected to the neutral position in the gearbox.

When not in the neutral position in the gearbox the automatic disconnection of the torque transmission system is controlled before the starter disconnection is made by the control unit.

When not in the neutral position in the gearbox the automatic actuation of the car brake or the car stop, ie the parking locking device, takes place and the automatic disconnection of the torque transmission system is controlled before the starter disconnection is made by the control unit.

After disconnecting the starting device via the control unit, the torque transmission system is automatically disconnected.

The torque transmission system is automatically disconnected when the operator operates to start the engine and the starter is disconnected via the control unit.

After the operator's operation, the control unit asks the sensor to detect whether it is connected to the neutral position on the transmission, and if it is connected to the neutral position, the starter is removed to start the engine and if it is not connected to the neutral position the brake is automatically activated. The torque transmission system is then automatically disconnected and a starter disconnect occurs to start the engine.

When an attempt is made to start the engine and the engine starter is removed, the engine starter starts the engine, such as an internal combustion engine.

If an attempt is made to start the engine and the engine starting device is not removed, the engine starting device prevents the engine from starting, such as an internal combustion engine.

It is also advantageous if the engine is started by the driver or automatically.

After switching on the car ignition, i.e. after energizing the car circuit, when the control unit is activated and tries to start the engine, the control unit is returned to the actual gear position by a sensor that detects the gear position and the gear is When connected to the gearbox the torque transmission system is disconnected and the engine is running.

The present invention includes an apparatus for controlling an automatic torque transmission system including a drive unit such as a motor, an automatic torque transmission system and a gearbox, an actor and a control unit which can be controlled by a control unit for operating the torque transmission system. Wherein the control unit is arranged in signal connection with at least one sensor and is an electronic unit such as an engine electronic device and / or an engine starter, an operating part on the driver's side for operating the vehicle assembly and starting the vehicle engine. Can be applied.

The control unit accepts and processes sensor signals from sensors that detect that the control unit is connected to the neutral position in the gearbox after the operator has operated it, and when the control unit is not connected to the neutral position in the gearbox the control unit starts the engine. Without disconnecting the starter, the starter disconnection takes place and the engine starts automatically to start the engine after an attempt is made to start the engine within a defined time when connected to the neutral position.

It is advantageous if the set time is in the range between 0.1 and 10 seconds.

It is convenient if the automatic engine starts only when the brakes are activated.

It would be advantageous if the device embedded in the motor vehicle was operated according to the invention.

For parking locking the gear can be connected and the torque transmission system can be closed. Another mechanical locking is braked in the gearbox for parking locking.

1 shows a drive assembly 2, such as an internal combustion engine, or a hybrid drive assembly with an electric motor / energy accumulator, a motor vehicle 1 comprising a torque transmission system 3 and a gearbox 4, the axis 5 of which is represented. It is mounted behind the gearbox and drives two drive shafts 7a, 7b by means of a differential device 6 which drives driven wheels 8a, 8b. The torque transmission system 3 is made of an automatic torque transmission system. The torque transmission system 3 is a friction clutch comprising a flywheel 9, a pressure plate 10, a clutch disc 11, a separating bearing 12 and a separating fork 13 and the separating fork is a master cylinder 16. Can be controlled by the actor 15 including the hydraulic line 17 and the subordinate cylinder 18. Alternatively, a separate bearing 12 is used, which is operated by a mechanical, electric motor or hydraulic separation member, such as a central separation member coaxial with the gear input shaft.

The actor 15 is an electric motor that operates the master cylinder piston 20 via a gear combination (not shown) so that torque can be connected or separated through the hydraulic line 17 and the subordinate cylinder 18. It is shown as an actor under hydraulic action with 19). The actor 15 also includes an electronic device for operating and controlling the actor 15, that is, a power electronic device and a control electronic device. The actor is equipped with a leak bore 21 connected to the hydraulic tank 22 for applying hydraulic pressure. The control unit is integrated in the actor 15 but may be installed in a separate housing.

The vehicle 1 including the gearbox 4 has a gear shift lever 30 which can be operated manually. This gear shift lever is operated by the driver to perform an operation such as shifting a gearbox. It is possible to connect the gears in the selection gate of the gearbox by means of a gear shift lever or to a neutral position in the gearbox. At least one shift detection sensor 32 is coupled to a manually operated gear shift lever and detects the shift intention of the driver from the movement of the shift lever and the force biased by the driver. If the driver then operates the gear shift lever to disconnect, change or connect the gear, the driver's shifting intentions appear.

In addition, at least one gear detection sensor 31 may be mounted to the shift lever and / gearbox to sense the actual connected gear and / or the actual gear position, such as the actual gear translation. The gear detection sensor 31 is at least one analog and / digital sensor or switch. At least one sensor directly or indirectly detects the position of the shift component inside the gearbox.

In addition, the sensor 31 may be formed as a neutral position sensor that generates a signal when connected to the neutral position in the gearbox. Not only does this sensor accurately detect connected gears, it also detects whether the neutral position of the gearbox components is present. This kind of neutral position sensor is an analog or digital sensor that, when placed in the neutral position, prompts you for the location of the parts inside the gearbox. If the part is in a fixed position, it is neutral. If the part is not in a fixed position, it is not.

In addition, the vehicle is equipped with a speed sensor 33 for sensing the speed of the gear output shaft and the wheel speed, respectively. A throttle valve sensor 34 and a speed sensor 35 are also provided, where the throttle valve sensor senses the throttle valve position and the speed sensor senses the engine speed.

The gear detection sensor detects the position of the shifting component built into the gearbox or the gear connected to the gearbox so that the gear actually connected is displayed on the control unit according to this signal. When an analog sensor is used, the gearbox's built-in shifting motion is detected so that the next connected gear can be quickly identified.

Actor 15 is fueled by a battery, which may have a permanent power connection. The power supply of the control unit and / or the actor is by means of a switch.

The motor vehicle comprises a multiphase switch, such as an ignition switch 41 which can be activated by an ignition key. When the switch is in the off position, the ignition key can be moved into a switch of the type that can be activated by the ignition key. In this position, the car assembly is usually inactive, and each assembly may run for a fixed amount of time. The car assembly is activated at one position on the switch that leads the switch to the on position. In this position of the switch the switch of the ignition is turned on so that an electrical system such as an automatic torque transfer system or a control unit of the other assembly can be activated. In other switch positions, the vehicle drive unit, such as the internal combustion engine, is started and the starting device of the internal combustion engine 2 is activated via the lead wire 42.

The signal is transmitted through the lead 43 to the electrical unit of the actor 15 and when the ignition device is switched on in accordance with this signal, the actor 15 is operated together with the control device.

The motor vehicle includes a sensor or switch 44 which is a brake switch connected to the control unit by a signal lead wire 45. At the same time the brake light or display can be activated by the switch via the signal lead. The brake switch detects the operation of a brake such as the brake 48 or the parking brake 49. This type of switch can detect the operation of pedals or other moving parts of the brakes.

When the ignition device is not switched on, that is, when the switch 41 is opened, the brake is actuated and the control unit of the actor 15 is connected via a signal to close the switches 44 and 46 via the connecting lines 45 and 47. When operating a gear shift lever, such as shift lever 30, to actuate and release the gear before the ignition is activated by the ignition key, the reaction of the automatic torque transfer system occurs and the clutch can be released at the appropriate time. have.

The described embodiments are also not limited to devices operated by hydraulic pressure, but can also use devices that transmit purely mechanical forces to separate the torque transmission system in use. This type of device operates the separate bearing directly via a rod linkage or a flexible linkage.

The switch 44 may be made of a sensor such as a brake light switch, but is not limited to a function as a brake light switch. As described above, it has other functions, such as actuating an alarm system or a central locking lock and unlock device.

1 is a schematic diagram of a motor vehicle 1 including a drive unit 2, such as an internal combustion engine, a torque transmission system 3, and a gearbox 4 in a drive train. Also shown is a differential device 6 and wheels 8a, 8b driven by an output shaft.

Wheel sensors are mounted on the wheels to detect wheel speeds. In terms of function, speed sensors belong to other electronic units such as ABS. The at least one wheel speed and the gear speed can be determined by the control unit from the at least one wheel speed. The sensor 33 detects the speed of the shaft 5 which is proportional to the speed of the gearbox or proportional to the wheel speed.

The drive unit 2 may also be formed as a hybrid drive including an electric motor, a flywheel having a freewheel and an internal combustion engine.

The torque transmission system 3 is formed of a friction clutch, where the torque transmission system may be formed of a magnetic clutch, a multiplate clutch, a torque converter or other clutches. This friction clutch can be formed as an automatically regulating clutch that regulates wear.

The control unit 15a and the actor 15 are also schematically shown. The control unit 15a may be formed as an integrated control unit for adjusting and controlling the torque transmission system, and may apply other electronic units or actors. The engine electronics unit can also be integrated into the control unit. Likewise, the control unit, engine and other units of the torque transmission system are mounted separately and connected to each other via signal lines. The control unit 15a is equipped with a computer unit so as to process, store and transmit input signals and system values. The control unit also generates control values and / or signals for controlling the actor to operate.

The torque transmission system 3 is connected to a flywheel, which is divided into a flywheel comprising a damping device between the first mass part and the second mass part, the first mass part and the second mass part with starting gear ring. to be. The clutch includes an energy accumulator such as a leaf spring and a clutch cover as well as a clutch disk having a pressure plate and friction lining. The self-regulating clutch has a wear control device where a sensor, such as a force or path sensor, is provided that senses a situation that requires adjustment.

The torque transmission system is operated by a hydraulically actuated separating member 13, such as a hydraulic, central separating member, which can support the separating bearing 12 and the clutch is connected and disconnected by biasing. However, this separating member may be formed as a mechanical separating member for operating and controlling the separating bearing or a comparable component thereof.

Actors 15, such as actuating units, control via hydraulic lines 17, hydraulic media, such as a central member, to connect and disengage clutches.

The control unit 15 is connected with the drive unit of the actor via a signal connection line so that the control signal and the sensor signal or the operation state signal are changed and transmitted. In addition, a signal connection line is provided, through which the control unit is connected in signal connection with another sensor or electronic unit. Other electronic units are for example engine electronics, ABS electronics or anti-slip controls. The sensor is also a sensor for detecting an operating state of a vehicle, for example, an engine or wheel speed sensor, a throttle valve position sensor, an accelerator pedal sensor, or some other sensor. The signal connection line 15 is connected with a data bus, such as a CAN bus, through which the data of a vehicle or other electronic unit is provided. This is because the electronic units are usually connected together through a computer unit.

The motor vehicle is preferably equipped with an electronic accelerator pedal 50 or a load lever, which controls the sensor 51, by which the engine electronics are connected to the signal line 52 of the engine 2. Through the throttle valve position, injection time, ignition time and fuel supply. The electronic accelerator pedal 50 including the sensor 51 is connected to the engine electronic device through a signal line 52. The engine electronics are signal-connected with the control unit 15a via signal leads. Electric motor throttle valve control is convenient, where the position of the throttle valve is controlled via the engine electronics. Direct mechanical connection with the accelerator to the system is no longer necessary.

The motor vehicle includes an engine starter 53, which controls the engine electronics to start the engine when an attempt is made to start the engine by the driver by operating the ignition key on the ignition lock 41. do. The engine starting device consists of an electronic starting device which automatically starts the engine if an initial signal is generated from an operating part, such as an ignition key. The engine starting device also includes a starter and an electric device for starting the engine.

If the starting device is removed by the control unit 15a and the engine electronics, the starting action will be started. The starter can be controlled and energized if the starting device is disconnected. If starter disconnection does not occur, electrical measurements are made and the starter does not start the engine. For example, the relay may be locked or the power supply to the starter via the electronic unit may be interrupted. The control unit may set the queried starter disconnect bit when there is an attempt to start. The starter disconnection bit is set to zero when there is no starter disconnection.

Based on a parked car with no engine running, the car can be parked by the driver with gears connected to the gearbox or caught in a neutral zone. After parking the car and switching off the drive motor, the control unit of the automatic torque transfer system closes the torque transfer system after a set time or after exceeding another controlled state. It is convenient if the control unit is kept in operation with other functions during the post-operation time after the vehicle and the drive motor have ceased to operate, the post-operation time closes the torque transmission system at the end and the control unit is inactive. The present invention relates to patent application DE 19619348, the contents of which are included in the detailed description herein. The invention also relates to patent application 19602874, the content of which is also included in the detailed description herein.

FIG. 2 is a block diagram 100 illustrating a control process when starting an automobile or an automobile drive motor, particularly when there is an operation of an ignition key or switch, a signal card or other components.

In block 101 the ignition device is activated by an ignition key so that the control unit of the automatic torque transfer system is activated. The operation is the operation of an integrated control computer which must be switched on or switched on, so that the computer or control unit ensures its operating capability. In block 102 it asks if the gearbox is in the neutral position or in the neutral position.

The question is solved by asking the sensor or checking the sensor signal, which only indicates this position when the gearbox is in the neutral position. The position of the shift lever at the selection gate can be separated by a sensor. In this case this is irrelevant to seeing whether the shift lever is in the selection gate at this position while the shift lever is in the neutral position. In addition, since the gear detection sensor can detect the position of the shift lever in the region of the entire selection gate, the sensor senses the position between the gear position connected to the neutral region and the gear position connected to the neutral region. The question of whether it is in the neutral area is not limited to the question of whether or not the sensor signal line lies in the set point area corresponding to the neutral position when using the sensor of the type described above. Sensor values may be evaluated to recognize the actual gear position and to compare whether the actual gear position is neutral or not.

The present invention also relates to application DE 19548799, the contents of which are incorporated herein by reference.

The question is whether there is a sensor value corresponding to the connected gear, where it is determined whether the computer value is negative or not in the neutral zone.

If the answer to the question is affirmative in block 102, then it is in the neutral position, and in block 103 the starting device is disconnected and the engine is started by the starting device, with the operator moving the ignition key to the neutral position to start the engine. Move. There is also another possibility of starting the engine by the driver when the ignition is switched on by means of a button or switch. In this case the starting device is activated and the engine is started.

If the clutch is in a neutral position in the gearbox when it is closed or opened, the engine will start. The clutch can be held in its actual position while being started by the driver. Alternatively, the clutch can be opened automatically before the starter is disconnected and the engine is started through the control unit and actor operation.

If the answer to the question is negative in block 102, ie the gear is caught in the gearbox, then in block 104 the clutch opens automatically and at least one car brake, such as a parking brake or brake, is automatically activated. This brake acts automatically or starts a little faster than opening the clutch. At least one brake actuation represents a safety value to keep the vehicle safe against unintended side effects. Because when the car is parked on the slope with the gears connected and the clutch closed, a parking lock is opened to open the clutch and the car can make an unplanned rollover. If the gearbox is geared and the vehicle is parked with the clutch open, the operation of opening the clutch can be stopped at block 104. In block 105, the starting device is removed. When there is operation by the driver to start the engine, the engine is started by the starter as shown in block 106.

In block 107 it is checked whether the throttle valve or the accelerator pedal is in operation or a switch such as an idling switch or a sensing switch. Other values may be sensed that indicate the operation of the accelerator pedal by the driver.

If the throttle valve or accelerator pedal is actuated, then in block 108 the brake actuated is removed and the torque transmission system, such as the clutch, is closed to start the vehicle, thus allowing a conventional method of starting the vehicle. If the throttle valve or accelerator pedal is not actuated, the brake is released at block 109 and the clutch is closed to move the vehicle forward. The car preferentially moves forward with safety in mind. This safety is characterized by a speed controlled movement of the vehicle with a limited engine moment used for creeping.

3 shows a flow chart 150 for controlling the starting device detachment when there is an attempt by the driver to move the vehicle. In block 151 the control unit is activated if the ignition key or other control component is activated and is not actuated by any other signal. If the control unit is ready for operation, at block 152 the control unit evaluates the gear position sensed by the neutral position sensor or the gear sensor. If a neutral gear is caught in the gearbox, the engine is started when an attempt is made to start the car by the driver, such as by removing the starter in block 153 and manipulating the ignition key in the engine start position. If the question in block 152 indicates that the neutral position of the gearbox does not exist, then block 154 is checked for gear connection. The gear can be assumed to be connected when no neutral position exists. The assumption can be made even if the gears are not actually connected. Because the operating path usually exists between the neutral position and the connected gear position.

If a neutral position does not exist and the gears are connected, the torque transmission system, such as the clutch, is moved to a partially open connection in the closed connection position (see block 155). The torque transmitted by the torque transmission system is reduced to the set minimum moment. The minimum moment is determined from one moment so that when the gear is connected to the gearbox it is possible to keep the vehicle on the slope via the engine drag moment. It is advantageous if this minimum moment is an area between 1/10 and 1/2 of the maximum engine moment or a value between 50 Nm and 100 Nm.

This allows for quick disconnection of the torque transmission system when needed. In block 156, the starting device is not disconnected.

4 is a block diagram 200 that can be applied to start an automobile engine and describes how a driver operates an ignition key to operate an automobile or an automobile assembly. When the ignition is switched on, all assemblies of the vehicle are activated (block 201). However, some assemblies may operate according to other signals.

In block 202 it is asked if it is connected to the neutral gear or the neutral position in the gearbox. There is no force locking connection between the gear input shaft and the gear output shaft when connected to the neutral gear. If the neutral gear is not connected and the gear is connected to the gearbox, the clutch can be connected or closed to ensure the parking lock. If the neutral gear is not connected, no starter is removed in accordance with block 203. The vehicle engine may be started by the starter when the driver attempts to start the engine.

If the neutral gear is jammed in the gearbox, block 204 asks whether the gear detection or neutral gear detection works without error. If there is an error, the starting device disconnection in block 203 is not guaranteed. When there is an error in the gear or neutral gear detection, block 205 asks whether at least one automobile brake, such as brake and / parking brake, is actuated. If the brake is not actuated, the starting device disconnection is not guaranteed in block 203. If at least one brake is automatic, then the starting device disconnection is ensured at block 206 and the vehicle starts to move when an attempt is made to start the engine by the driver.

Fig. 5 shows a block diagram 250 for controlling a torque transmission system such as a clutch when there is operation of a driver to start the engine and when operating the control unit and the vehicle assembly of the torque transmission system. In block 251 the control unit of the car / car assembly and / or torque transmission system is operated by a driver's operation, such as switching on or energizing. This operation is preferably carried out via the ignition key. After operating the control unit in block 252, block 251 asks whether gear detection or neutral gear detection operates without error. Another self test may be performed at block 252. If the control unit evaluates that the gear detection is error free, then the starter is not disconnected at block 253. If the gear detection is determined to be in error at block 252, it is asked if it is connected to the neutral gear in block 254. If the neutral gear is engaged, the starting device is disconnected at block 256. If not connected to a neutral position, block 255 asks whether at least one brake is actuated. If the brake is not actuated, the starter disconnection at 253 is not guaranteed. If at least one brake is actuated, the starter disconnection in block 256 is guaranteed.

FIG. 6 shows a block diagram 300 for controlling a torque transmission system such as a clutch when there is a driver's operation to start the engine and when operating the control unit and vehicle assembly of the torque transmission system. In block 301 the control unit of the car / car assembly and / or torque transmission system is operated by a driver's operation, such as switching on or energizing. This operation is preferably carried out via the ignition key. After operating the control unit in block 302, block 301 asks whether gear detection or neutral gear detection operates without error. Another self test may be performed at block 302. The starter is not disconnected at block 303 if the control unit evaluates that the gear detection is error free. If in block 302 the gear sensing is determined to be in error, it is queried whether it is connected to the neutral gear in block 304. If the neutral gear is engaged, the starting device is disconnected at block 306. If it is not connected to the neutral position, in block 305 it is asked if there is a shift signal. A shift signal is generated by the control unit if the sensor detects the actuation of the shift lever or the force acting on the shift lever. In this case, the operation is understood as the driver's shifting intention. If there is no intention of shifting, the starting device disconnection is not guaranteed at block 303. If there is a shift signal, the starter is disconnected at block 306.

FIG. 7 shows a block diagram 350 illustrating a method of using the device according to the invention to disconnect a car starting device for starting a car or a car engine. In block 351 the automotive circuit is closed by operating the ignition key and the automotive assembly is activated. The automotive clutch is generally in the closed position before the control unit of the automatic clutch is activated. After operating the power unit of the vehicle control circuit or after operating the control unit of the automatic torque transmission system such as the clutch, the clutch remains open in operation. If the clutch is connected or disconnected in operation, after disconnecting the control unit it remains initially connected or disconnected. In a non-operated vehicle the connection of the clutch depends on the gear connected to the gearbox or the position of the connected gear. The clutch can be engaged when the drive gear is in the gearbox, similar to when the neutral position is in the gearbox. However, the clutch may be detached.

In block 352 the movement of the gearbox or shift lever is shown to change the actual gearbox or the presence of this movement is queried. The question or indication indicates the driver's shifting intention. If no movement or action is present, the starting device is not disconnected, but if there is a movement indicative of the shift intent signal, it continues at block 353. It is advantageous if block 352 continues after first detecting the driver shift intent in block 352. In block 353 it is asked if it is connected to the neutral position in the gearbox. If connected to the neutral position, in block 353 the starter is disconnected and the vehicle starts to operate when the driver attempts to start the engine. If the neutral gear is not engaged, the clutch is opened at block 354 and at least one brake is activated before the starting device is disconnected at block 355.

8 shows in block diagram 400 a method according to the invention for controlling a torque transmission system and a motor vehicle. In block 401 operation of the vehicle / individual assembly and / or control unit is achieved by operating the ignition key. In block 402 the embedded electrical circuit is closed when the ignition key is in operation to indicate that the assembly or control unit is activated. In block 403, the closed clutch remains closed and the open clutch remains open. In block 404, the starter is queried when the driver attempts to start the engine by operating the ignition key. In block 405, the starter disconnection is determined by asking for gear removal via a gear sensor that indicates whether or not the neutral gear is connected in the gearbox after asking the starter in block 404. Neutral gear connection is queried at block 406. If the neutral gear is engaged, the starter is disconnected at block 407 and the engine is started. If no neutral gear, no starting device disconnection occurs at block 408. By operating the shift lever, the clutch is released only when there is a shift signal.

9 shows a torque transmission device and a vehicle control method including the same in a block diagram 450. In block 451 operation of the vehicle / individual assembly and / or control unit is accomplished by operating the ignition key. In block 452 the embedded electrical circuit is closed when the ignition key is in operation to indicate that the assembly or control unit is activated. In block 453, the gear sensing sensor determines whether the gear is connected to the gearbox or whether the gearbox has a neutral gear. In block 454, the closed clutch remains closed and the open clutch remains open. In block 455, it is asked whether the starting device should be disconnected when an operator attempts to start the engine by operating the ignition key. In block 456, it is asked whether the starter is connected to the neutral gear in the gearbox when it is disconnected. If it is in neutral gear, in block 457 the starting device is disconnected and the engine is started. If no neutral gear is present, no starting device disconnection occurs at block 458. The clutch remains closed until the shift signal is input.

In Figures 8 and 9 the starting device is disconnected if all the necessary conditions are met when the neutral gear is engaged and the clutch is closed. In this state, the gear input shaft is dragged while starting the engine by starting the engine with the clutch connected. It is advantageous if the clutch is quickly disengaged with the engine running in such a way that the drag moment of the gearbox has the least effect possible.

10 shows in block diagram 500 a method according to the invention for controlling a torque transmission system and a motor vehicle. In block 501 operation of the vehicle / individual assembly and / or control unit is made by the driver by operating the ignition key. When the ignition key is in operation, the electrical circuits of the built-in vehicle are closed and the assembly or control unit is activated. In block 502 it is determined by the sensor system whether at least one brake, such as parking brake and fixed brake, is actuated. If the brake is not actuated, no starting device disconnection occurs at block 504. If the brakes work, block 503 asks if the neutral gear is caught in the gearbox. If the neutral gear is engaged, the starting device is disconnected at block 505.

11 shows in block diagram 550 a method according to the invention for controlling a torque transmission system and a motor vehicle. In block 551 operation of the vehicle / individual assembly and / or control unit is made by the driver by operating the ignition key. When the ignition key is in operation, the electrical circuits of the built-in vehicle are closed and the assembly or control unit is activated. In block 552 the clutch is held in its occupied position before operation. In block 553 it is determined by the sensor unit whether at least one brake, such as parking brake and fixed brake, is actuated. If the brake is not actuated, the starting device is disconnected at block 554. If the brakes work, block 555 asks if the neutral gear is stuck in the gearbox. If the neutral gear is engaged, the starting device is disconnected at block 556.

It is also advantageous if safety aspects are taken into account and the requirements are met before the engine starting device is removed. Under these conditions, closed safety contacts such as door contacts, engine hood contacts, sheet contacts and / belt contacts are queried. This contact ensures that no situation can inadvertently compromise safety.

12 shows a selection gate 600 made of a shift gear combination, such as a five speed gearbox. Four or six speed gearboxes can also be used. It is not limited to a specific gearbox, but can be used for various gearboxes such as a shift gear having a manually operated shift lever.

The gearbox is shifted by an actuated shift lever 30, such as a gear shift lever. The select gate 600 includes a shift gate 601 and a select gate 602 between the shift gates. The operation in one shift gate is considered a shift motion and the operation in the select gate is considered a select motion.

Region 603 represents the narrow neutral region in which the shift lever is located when the neutral gear is engaged in the gearbox. There is no force locking between the gear input shaft and the gear output shaft in this area. The neutral region 603 extends over the entire selection gate 602 and some regions of the shift gate 601.

Region 604 corresponds to the region in which the gear is considered to be connected or shifted to the gearbox. There is an area 605 in which no gear is shifted between the areas 603 and 604, but the narrow neutral area is maintained.

If the shift lever is in the area 603, it is in a neutral position, and if the shift component or the shift lever in the gearbox is monitored by at least one sensor, it can be detected that there is a neutral gear. Comparing the value indicated by the gearbox position sensor or the gear-sensing sensor with a reference value, it is possible to determine whether or not it is connected to a neutral position in the gearbox. This is done by sensing whether there is a narrower neutral area or not. If there is no neutral position in this position, it is not clearly sensed whether the gear will shift in the gearbox or not.

The connected gear may be detected if a sensor value characterizing region 604 is detected by comparison with one of several values.

As sensors, analog actuated sensors, such as acoustic sensors, potentiometer sensors or other sensors can be used. Digital actuation sensors may also be used. This may be a switch, a button, or it detects the selected position.

The apparatus and method described above is a shifting process of a gearbox, which is a non-loaded switching gear associated with an automatic transmission gear with an automatic clutch, is carried out by an actor which is controlled by the control unit and which can be controlled by the control unit.

13 shows in block diagram 700 a method according to the invention, ie a method of operating a motor vehicle comprising a device according to the invention. If the ignition and time of the vehicle are delayed in block 701, the control unit of the automatic clutch stops operating via the ignition key or other component. Therefore, the engine of the car also stops working. Since the clutch is connected (block 702) after switching off the vehicle ignition before the control unit stops operating (block 702), the gear is parked locked with the gearbox connected and the vehicle does not accidentally turn over.

After switching on the vehicle ignition in block 703 the control unit is operated in block 704 and the microprocessor of the control unit is booted. This means that programs are loaded from storage, memory is constructed and data is loaded from volatile or nonvolatile memory, and sensor data is sent and entered.

In block 705 the automatic clutch is controlled by the control unit and is connected for a fixed time of 100 ms to 500 ms, preferably 300 ms. It is convenient to reach a defined starting state when the hydraulic line between the actor and the automatic clutch system is activated. The hydraulic path is relaxed and the system is calibrated.

Block 706 detects the state of the connected gear and generates a sensor signal indicative of this state. It is asked whether it is connected to the neutral zone in the gearbox. If it is not connected to the neutral zone, no clutch action occurs at block 707 and the clutch remains closed. The engine can not be started at block 708. This means that under the conditions described above, the control unit of the automatic clutch sends a signal to control the engine and does not start the engine. Similarly, a relay can be activated that prevents powering the starting device to start the engine.

In block 709 it is detected whether there is a shift lever movement, such as a shift intent. This may occur because a force or path sensor is attached to the vehicle shift lever or to a part indicating whether the shift lever has an operating movement. If there is no shift lever movement in block 709, the clutch is disabled in block 710. If the shift lever movement occurs in block 709, then in block 711 the clutch is activated and released.

At block 717, a signal is detected at the sensor that detects the connected gear and indicates this condition. It is queried whether the neutral zone is connected to the gearbox. If it is not connected to the neutral zone, the engine can be kept from starting at block 718 and if connected to the neutral zone the engine can be started at block 719.

No clutch action occurs at block 712 if it is connected to the neutral region at block 706. If the driver operates the ignition key to start the engine, the engine is started (see block 713). In block 714, it is asked whether the shift lever movement is occurring or whether the engine is running. If the engine speed is equal to or greater than the set threshold of the engine speed, such as 200 1 / min, it is possible to determine whether the engine is running. If it is not above the set threshold, no clutch actuation occurs at block 715 and if it is above the set threshold, the clutch is released at block 716. The process then continues at block 717 as described above.

14 is a block diagram 750 illustrating an embodiment of a method according to the present invention. In block 751 the car ignition stops working, so the whole system is not working. The clutch is closed at block 752 to park the lock before leaving the control unit inactive.

By operating the car ignition in block 753, in block 754 the microcontroller of the control unit begins to operate. After starting to operate in block 754, in block 755 it is asked whether a neutral gear is stuck in the gearbox. This can be seen by checking the sensor or signal. If the neutral gear is not jammed in the gearbox, in block 756 the starter is not separated by the control unit of the automatic clutch. This information is communicated to the engine control unit via a data bus such as a CAN bus. If the starting device is not disconnected, the engine controller controls the engine not to start when the driver is willing to start, such as operating the ignition key to start the engine. Closing the clutch at block 757 is performed for 300 kPa for hydraulic pressure compensation. Then in block 758 it is asked whether the shift is intended, i.e. if the shift lever movement. If there is a shift intent, the clutch opens in block 759. If there is no shifting intention, the system is placed in the standby loop until the shifting intention is created through the operation of the shifting lever.

If the neutral gear is jammed in the gearbox in block 755, the starter is disconnected by the control unit of the automatic clutch in block 760 and transmitted to the engine control unit. If the ignition key is operated by the motor vehicle driver to start the engine, the engine is started by the engine control unit. In block 761 the clutch is closed for 300 kPa for hydraulic compensation of the delivery path. In block 762 it is asked if the engine is running or if there is a shift intent. The engine is activated if an engine speed of n _mot 200 rpm is detected or transmitted from the engine control unit to the control unit of the automatic clutch. The presence of a shift intent is assessed by sensing the force or movement applied to the shift lever. If there is a shift intent or the engine is actuated, the clutch is opened at block 763, and if there is no shift intent or the engine is not actuated, the system remains in the standby loop 764 until the engine is actuated or a shift intent occurs.

15 is a block diagram 800 of an embodiment illustrating a method according to the present invention. In block 801 the electronic control of the automatic clutch is activated by an ignition key. In block 802 the microprocessor of the electronic control unit is booted.

In block 803 the clutch is closed and the clutch is closed to keep the clutch closed or to relax the hydraulic path between the actuator and the clutch, such as an actor. In block 804 it is asked if it is in the neutral gear in the gearbox. If in neutral gear, the engine is removed to start at block 809 and the clutch is opened at block 810. If it is not caught in the neutral gear in the gearbox, it remains in block 805 not ready for start up, ie the starter is not disconnected by the control unit of the automatic clutch. Block 806 asks if there is a shift lever motion and force generated according to the shift intent by the driver. If the shift lever movement and force are present, the clutch is opened at block 808, otherwise the clutch is closed at block 807.

FIG. 16 shows in block diagram 850 an embodiment in which the control unit is operated at block 851 and thereafter the microprocessor is booted at block 852. In block 853 the clutch is closed for 300 kPa for hydraulic compensation of the hydraulic path. In block 854 it is asked whether it is connected to the neutral gear in the gearbox. If the sensor indicates that it is in neutral gear, the starter is disconnected by the control unit of the automatic clutch at block 858 and this signal is transmitted to the engine control unit via the CAN bus, so when an attempt is made to start the engine, Can take In block 859 it is asked if the engine is running, if there is a shift intent, ie if the shift lever is in motion. If there is no shifting intent, it stops in the waiting loop until the answer to this question is positive. If there is an engine speed or shift intent, the clutch is opened at block 860. If a gear other than a neutral gear is connected to the gearbox, it will not work when attempting to start the engine because in 855 the starting device is not disconnected. Then in block 856 it is asked whether there is a shift intention as a result of the shift lever movement. If there is a shift intent, the clutch is opened at block 857, otherwise it waits in the wait loop until the answer to the shift intention is affirmative.

17 shows a block diagram 880, which is another embodiment. The control unit of the automatic clutch is activated in block 881 and then the microprocessor is booted in block 882. In block 883 the clutch is closed for hydraulic compensation of the hydraulic path between the clutch actuating part, such as the separating bearing, and the clutch actuating actor. This compensation takes place, for example, for 300 ms. In block 884 it is asked whether it is connected to the neutral gear in the gearbox. If the neutral gear is engaged, the engine is activated at block 889, ready to start by disconnecting the starter, and the engine is started when an operator attempts to start it. In block 890, it is asked if the engine is running or if the shift lever is in motion. If there is movement of the shift lever, the clutch is opened at block 892, otherwise the clutch is closed at block 891. If there is a neutral gear in the gearbox, the engine is blocked by starting the starter in block 885 without starting the engine in block 885 when an attempt is made by the driver to start the engine. Then in block 886 it is asked whether there is movement of the shift lever. If there is movement of the shift lever, the clutch is opened (block 888), otherwise the clutch remains closed (block 887).

18 shows another embodiment in a block diagram 900. In block 901 the control unit of the automatic clutch is activated and in block 902 the microprocessor of the control unit is booted. In block 903 a leakage process is performed for hydraulic compensation of the hydraulic path, which is necessary if the operation between actuating actors or clutch disconnection devices includes a hydraulic path or other pressurized medium path. If there is a mechanical connection between the parts, no leakage process or compensation process is necessary. In block 904 it is asked whether the gearbox is in neutral gear. If the neutral gear is engaged, block 908 asks if the engine is running and the engine speed signal is correct or not, or if the clutch is already open, if the clutch is no longer closed or if the shifting lever is moving out of the neutral area. If the answer to this question is positive, the clutch is opened at block 910, otherwise closed at block 909. If there is no neutral gear in the gearbox, block 905 asks if the engine is running. If the engine is running, then it is operated via conventional driving methods at block 906 and if the engine is not running the clutch is closed or kept closed at block 907. Then in block 911 it is asked if the neutral gear is caught in the gearbox or if the clutch is open. If the neutral gear is engaged and the clutch is open, the starter is disconnected at block 912 so that the engine will run when the driver attempts to start the engine. If the clutch is closed without being caught in the neutral gear, the starter is not disconnected at block 913. The driving method shown in block 906 corresponds to the clutch operating method when the vehicle is in normal operation, when the clutch is opened, the clutch is opened and closed again at the end of the shifting process, and the vehicle is driven when the brake is applied with the gear in the stopped state. The clutch is closed or opened.

19 is a block diagram 940 illustrating a method of operating a device according to the present invention. In block 941 the control unit of the automatic clutch is

a) operate the ignition key to operate the car ignition

b) actuated by activating the brake.

Reference may be made here to DE-OS 19619348.6, the details of which are incorporated herein by reference.

The microprocessor of the automatic clutch control unit is then booted at block 942. The operation of the clutch does not occur within a predetermined time, and the operation of an actor such as a clutch actuating actor does not occur. In block 943 a signal is delivered by the microprocessor of the automatic clutch control unit, where signals from sensors and other electronic units can be read by the CAN bus. This signal is then checked for plausibility, i.e. the signal is checked to see if the value is within a specified range of values. If it is not within the specified range, it is determined that there is an error in the sensor or signal. In particular, signals are read and checked from the vehicle data bus, such as the gear signal generated at the gear sensor or the shift lever signal generated at the shift lever or the sensor on the shift block or the CAN bus. The gear sensor of the gearbox sensor unit detects the gear connected to the gearbox, the shift lever signal provides information about the shift lever movement, and the CAN bus signal is the engine speed, gearbox speed or wheel speed signal. However, this signal can be detected by its own sensor. In block 944 the signal of the sensor or other electronic unit is processed to determine the connected gear. In block 945 it is checked whether the engine speed is above a set threshold or whether the engine speed signal is a probable value. If there is an error in the engine speed signal, i.e. the engine speed signal is not probable, then the block 950 goes through an alternate process. Then, if there is no error in the engine speed, it asks whether there is an error in the shift lever signal, that is, there is no sensor signal that detects the operation of the shift lever. If there is an error, the shift lever signal is replaced in block 947 by the gearbox sensor unit. If there is a shift lever signal, block 948 asks whether the gearbox sensor unit has a signal. If the signal is not correct, the replacement proceeds at block 954. If there is no error in the gearbox sensor unit, block 949 asks if there is a shift lever action or opening the clutch. If there is no shift lever action and no clutch opening action, then at block 950 it is asked whether the engine is started, ie whether the starter is running or whether engine speed 0 or 200 1 / min can be detected. If the answer to the question is affirmative in block 949 the clutch is open or remains open in block 952. Otherwise, if the answer is negative in block 951 after block 950, the clutch is closed. Then in block 953, if the gearbox is in neutral gear or the clutch is open, the starting device is disconnected.

When replaced in block 954, the clutch is closed according to the throttle valve action. This is necessary in order to easily connect the clutch by the driver when there is an error in the gearbox sensor system.In case of an error in the gearbox sensor unit, the connected gear cannot be detected, so adjusting the opening and closing speed of the clutch with the associated connected gear This does not happen easily because it does not occur. The starting device is then disconnected when the clutch is opened in block 955 and the automobile brake such as the brake or parking brake is actuated.

When the engine speed decreases, a fallback occurs at block 956, which detects an error in the gearbox sensor system. If there is no error in the gearbox sensor system, in block 959 the electronic control unit is inactive. The car cannot be driven. If there is no error in the gearbox sensor system, at block 957 the clutch is closed with the gear connected and the clutch is opened when there is a shift intent signal or when it is connected to the neutral gear in the gearbox. The shift signal indicates the operation of the shift lever. The starting device is then disconnected in block 958 when it is engaged in the neutral gear in the gearbox or when the clutch is open.

FIG. 20 is a block diagram 970 illustrating an example in which the embodiment illustrated in FIG. 19 is modified. In block 971 the control device is activated by operating the ignition key or by operating the ignition device or brake. Then the microprocessor of the automatic clutch electric control unit is booted. When booted, the actuation of the clutch or the actor acting the clutch does not occur. In block 973 the signal is received from the control unit and checked by probability check and in block 947 the batch data is calculated and processed. In block 957 it is checked whether the engine speed is reduced or not. If the engine speed drops, an alternating action will occur. Then, block 988 asks if the gearbox sensor is in error. If the gearbox sensor unit has an error, the system stops operating (see block 989). If there is no engine speed drop, a check is made at block 976 for errors in the shift lever sensor signal. If there is an error, in block 977 the shift lever signal is replaced by a signal from the gearbox sensor unit. If not, ask block 978 if there is a drop in the gearbox sensor unit. If there is a drop in the gearbox sensor unit, an alternating action occurs, which means that the clutch is actuated with the throttle valve action, and in block 994 the clutch is closed by the throttle valve action as a function of the throttle valve action. Closing the clutch according to the throttle valve actuates over time. In block 995, if the clutch is open and the brake is actuated, the starter is disconnected. After switching on next to blocks 978 and 988, the system is queried whether it is in the first 300 ms. If it is in the first 300 ms, if the neutral gear is detected in block 992 or the clutch is open, then if the clutch is not in the first 300 ms before the starting device is released, then if the gear is connected in block 980 or 991, ie the gear The box asks if the neutral gear is connected or not. If the answer to this question is affirmative in block 980, block 981 asks whether the engine is running. If the engine speed is below zero or below a set point, for example 200 rpm, it is activated via the drive method in block 982. Otherwise, at block 983 the clutch is closed. If the gear is not connected to the gearbox, ie the neutral gear is not engaged, it is changed from block 980 or 991 to block 984. Here it is asked if the shift lever is in neutral or if the clutch is no longer closed or if the clutch is already open or if the engine is running and if the engine signal is correct. If the shift lever is in neutral, the clutch is open, the engine is running and the engine signal is correct, the clutch is opened in block 986, otherwise closed in block 985. Thus, if the answer is affirmative in block 991, the clutch is closed according to the time gradient as a function of time. The starting device is then disconnected if it is caught in the neutral gear or the clutch is already open in block 987. If the starting device is disconnected, the engine will start running when the driver attempts to start the engine, otherwise the engine will not start. In other words, the engine control unit does not start the engine.

It is advantageous if the respective methods of the various block diagrams illustrating the embodiments are combined together.

The above-described method for controlling can be used as a normal operation control procedure. This method may be used as an emergency operation control method executed when a part of the automatic clutch device is wrong, such as when a sensor has failed.

When modifying the example shown in FIG. 13, the clutch can be disengaged in block 714 if the control unit receives a signal indicative of the starting device being operated from the engine control unit. When the starter is activated, the starter operating signal is received from the engine control unit via the CAN data bus. However, this modification may be incorporated in other methods shown in the other figures.
