Definitions
- the invention relates to a hybrid powertrain and a method for controlling a friction clutch of a hybrid powertrain of a motor vehicle with an engine coupled by means of a freewheel with a transmission input shaft of a transmission for transmitting the engine torque and an internal combustion engine starting and / or the motor vehicle driving electric machine, which friction clutch from a starting torque for starting the internal combustion engine by means of the electric machine and a thrust torque acting on the internal combustion engine in overrun operation of the drive train transmits transmitted torque to the internal combustion engine.
- Hybrid powertrains are well known in mass production applications.
- an electric machine in addition to a transmission input shaft driving an internal combustion engine, an electric machine is provided which serves as a generator in the overrun phase of the drive train and also in an electromotive mode, the internal combustion engine and / or the motor vehicle with the hybrid powertrain alone or in conjunction with the internal combustion engine supports supportive.
- a friction clutch is effective as a separating clutch, which decouples them from each other.
- a freewheel is arranged between the crankshaft of the internal combustion engine and the transmission input shaft of the transmission, which is arranged in the direction of a torque transmission from the internal combustion engine to the transmission blocking and overrolling in the thrust direction.
- the friction clutch is at least partially closed for this purpose. Furthermore, the friction clutch is closed when, for example, when the motor vehicle is stationary, the internal combustion engine is to be started in a cold or warm start by means of the electric machine or during a motor vehicle traveling or sailing solely by means of the electric motor.
- a starting torque is transmitted via the friction clutch, which is formed exclusively by the electric machine and / or by the kinetic energy of the motor vehicle.
- the summation torque is therefore a proportion of thrust torque and starting torque together and can the required transmission torque, the start of the internal combustion engine Be
- the object of the invention is therefore to propose an improved method for controlling a friction clutch in a hybrid powertrain and a hybrid powertrain with a smaller sized friction clutch.
- the object is achieved by a method for controlling a friction clutch of a hybrid powertrain of a motor vehicle with an engine coupled by means of a freewheel with a transmission input shaft of a transmission for transmitting the engine torque and an electric machine which starts the engine and / or the motor vehicle, which friction clutch from a starting torque to the start of the internal combustion engine by means of the electric motor and acting on the engine thrust torque in overrun of the drive train formed summation torque to the internal combustion engine, solved, wherein the voltage applied to the friction clutch summation torque is limited to a predetermined transferable via the friction clutch transmission torque.
- the friction clutch can be designed for the actually required transmission torque and thus for a lower transmission capacity, whereby costs can be saved.
- the friction clutch is depending on friction values of the Reibeläge the clutch disc and contact forces of a clutch actuator by specifying an actuator travel of the clutch travel closed only so far until the necessary transmission torque is transmitted. Higher torque components of the total torque are hidden by a slipping operation of the friction clutch.
- the friction clutch advantageously closes completely only when the coefficients of friction assume a minimum, calculated value and the calculated tolerance values are at the limit values.
- the clutch actuator is self-locking, for example, designed as a spindle actuator with a self-locking thread pitch of the spindle.
- the control of the friction clutch by means of a control device that outputs a Aktorweg for the clutch actuator from a predetermined transmission torque by means of a characteristic.
- the characteristic curve is clamped by the coefficient of friction and the Aktorweg and is adapted as needed, for example, regularly and / or after a number of coupling operations.
- An adaptation of the characteristic curve can be carried out, for example, by determining the Y-axis section in the form of a touch point, in which the friction clutch is just beginning to transmit moment, and a slope in the form of an actuator travel determined at a given moment.
- a drive train for carrying out the proposed method with a by means of a freewheel with a transmission input shaft of a transmission for transmitting the engine torque coupled engine and the internal combustion engine starting and / or the motor vehicle driving electric machine, a friction clutch, to which one from a Starting torque for starting the internal combustion engine by means of the electric motor and a force acting on the engine thrust torque in the overrun mode of the drive train formed summed torque applied, solved, the friction clutch is designed while maintaining a safety margin to a predetermined summation torque limiting transmission torque. Due to the limited transmission torque, the friction clutch can be designed for smaller moments to be transmitted. It is understood that in this case corresponding security surcharges, taking into account the tolerances of the individual coupling components, are provided.
- FIG. 1 shows a partial section through a hybrid powertrain 1 of a motor vehicle with an internal combustion engine, of which only the crankshaft 2 is shown, the transmission input shaft 3 of the transmission, not shown, the friction clutch 4 and the electric machine 5.
- the crankshaft 2 is about the torsional vibration damper 7 with the intermediate shaft 8 meshes and initiates the torque of the internal combustion engine via the input part 9 of the freewheel 10 in the transmission input shaft 3 a.
- the electrical machine accommodated on the housing 6 by means of the stator 11 is connected in a rotationally fixed manner to the output part 14 of the freewheel 10 by means of the rotor 13. Furthermore, the rotor 13 is rotatably connected to the input part 15 of the friction clutch 4.
- the output part of the friction clutch 4 is formed by the clutch disc 16 which is rotatably connected to the intermediate shaft 8.
- the clutch actuator 17 displaces the pressure plate 19 by means of the plate spring 18 axially and clamped by means of the leaf springs 20 rotatably and axially displaceable on the supported by the bearing 12 rotatably relative to the housing member 22 received support member 21 supported pressure plate 19 against the axially fixed counter pressure plate 23, so that the Friction linings 24 of the clutch disc 16 are braced and by forming a frictional engagement with pressure plate 19 and counter-pressure plate 23, the transmission torque from the rotor 13 and the transmission input shaft 3, bypassing the overrun in this torque direction freewheel 10 on the intermediate shaft and from there via the torsional vibration damper 7 on the crankshaft. 2 is transmitted.
- the start of the internal combustion engine takes place with the motor vehicle on the friction clutch 4 by applying the starting torque by the electric machine 5, wherein the friction clutch is just closed to the extent that the starting torque of the internal combustion engine is transmitted.
- the internal combustion engine can be started when the motor vehicle is moving by passing the kinetic energy applied when the transmission is engaged, which is provided, for example, by a sailing operation or sole drive of the electric machine 5, to the crankshaft 2 via the friction clutch 4.
- thrust torque can be transmitted from the transmission input shaft 3 to the rotor 13 and at the moment of transferring frictional clutch 4, which serves to obtain electrical energy or a thrust braking of the motor vehicle by means of the internal combustion engine.
- the friction clutch 4 is just closed or slipping operated so far that only the predetermined transmission torque is transmitted.
- the transmission torque is thereby designed so that both the starting torque and a desired thrust torque are transmitted securely, moreover, the friction clutch is used for their self-protection as overload protection, so that at larger upcoming thrust moments overloading of the friction clutch is prevented by setting slip.
- the friction clutch can be adapted to the maximum required moments and designed accordingly. In this way, a design attributable to peak moments, whereby the friction clutch can be dimensioned smaller despite life-long design.
