Definitions
- the invention relates to a method for starting an internal combustion engine in a hybrid vehicle, in which an electric motor of the hybrid vehicle accelerates to a predetermined speed and a, arranged between the engine and the electric motor hybrid disconnect clutch is moved in response to a to-be-transmitted target clutch torque in the closing direction.
- a method for controlling a starting clutch is known in which the starting clutch is in the drive train of a hybrid vehicle.
- the starting clutch which is arranged between the internal combustion engine and the electric motor, is closed by means of the electric motor in a first starting phase by means of a precontrol and in a second starting phase as a function of the acceleration of the crankshaft of the internal combustion engine.
- the stationary combustion engine is suitably towed.
- the clutch torque is either too large, i. the acceleration of the internal combustion engine is too fast, or the clutch torque is too low, causing start too slow or in extreme cases not at all.
- the invention has for its object to provide a method for starting a combustion engine in a hybrid vehicle, which works robust and ensures a safe start of the engine.
- the object is achieved in that in a first phase in which the internal combustion engine is, the target clutch torque for restarting the internal combustion engine in dependence on a Motorabstellposition of the internal combustion engine is determined.
- the desired clutch torque comprises friction and / or compression moments as a result of the engine stop position of the internal combustion engine. These friction and / or compression moments are different depending on the engine position and thus require different towing or Losr possessmomente for burning motor, which are taken into account when setting the nominal clutch torque.
- the friction and compression moments are temperature-dependent.
- the desired clutch torque thus varies greatly depending on these various parameters and is determined concretely for the respective current state of the internal combustion engine.
- the desired clutch torque is superimposed in the first phase of a proportion which takes into account a mass inertia and a target acceleration of the internal combustion engine.
- the target clutch torque to be set by the clutch is specifically directed to the structural conditions of the internal combustion engine.
- the desired clutch torque is determined as a function of a desired acceleration of the internal combustion engine derived from the dynamic torque.
- the dynamic torque which depends on the inertia and the target acceleration of the internal combustion engine, is taken into account.
- the consideration of compression and friction torque can be reduced or eliminated because the engine is already in motion.
- the desired clutch torque is regulated as a function of the desired acceleration of the internal combustion engine. This ensures that at any time of the restart of the engine, the desired desired clutch torque is set and thus the internal combustion engine is further accelerated.
- the hybrid disconnect clutch in a third phase, when the differential speed of engine speed and motor speed is less than a predetermined speed threshold, the hybrid disconnect clutch is fully closed. This ensures that the combustion engine is adapted as quickly as possible to the speed of the electric motor.
- a ramp function or a slip control is used to completely close the hybrid disconnect clutch.
- the ramp function is preferably to use, since in the slip function it can lead to speed jumps.
- FIG. 1 shows an embodiment of a drive train of a hybrid vehicle
- Fig. 2 Compression moments of the internal combustion engine as a function of the crankshaft angle
- Fig. 3 shows an embodiment of the method according to the invention.
- FIG. 1 shows an exemplary embodiment of a drive train 1 of a hybrid vehicle having an internal combustion engine 2, which has a crankshaft 3.
- An electric motor 4 has a rotor 5, wherein a hybrid separating clutch 6 is arranged between the electric motor 4 and the internal combustion engine 2.
- Another clutch which is designed in the embodiment shown as a torque converter 7, which may additionally have a lockup clutch, is disposed between the transmission 8 and the electric motor 4. If the internal combustion engine 2 exclusively transmits torque when the hybrid disconnect clutch 6 is closed, the electric motor 4 is designed to be de-energized, while the rotor 5 serves as the drive unit flywheel.
- both drive units 2, 4 transmit torque to the transmission 8.
- the hybrid disconnect clutch 6 is opened. If it is to be braked by means of the electric motor 4, the hybrid disconnect clutch 4 is opened and the electric motor 4 is operated as a generator. In addition, the drag torque of the internal combustion engine 2 can be used by closing the hybrid disconnect clutch 6 to achieve a greater delay effect.
- FIG. 3 shows a diagram which represents the course of a restart of the internal combustion engine 2.
- the engine 2 is first stopped and the hybrid vehicle is operated by the electric motor 4 while the hybrid disconnect clutch 6 is opened.
- the restart phase of the combustion engine sector 2 is divided into three phases.
- the electric motor 4 is accelerated to a predetermined speed.
- a corresponding desired clutch torque must be established.
- the build-up clutch torque depends essentially on two components.
- the first component MkuppPartl includes specific characteristics of the internal combustion engine 2, such as the friction and compression behavior.
- This shutdown position of the internal combustion engine 2 is related, for example, to an absolute angular position, ie, a clutch torque component is defined, which is engine shutoff position dependent.
- a clutch torque component is defined, which is engine shutoff position dependent. The reason for this is that the closer a piston is to top dead center, the higher the clutch torque must be to overcome the compression.
- FIG. 2 shows compression torques of the internal combustion engine as a function of the crankshaft angle ⁇ .
- the states of the internal combustion engine 2 are designed as follows:
- Discharge phase 540 ° ⁇ ⁇ 720 °
- MkuppPartl Mstart_eng ( ⁇ , Temp)
- a second component MkuppPart2 of the target clutch torque is considered, which can be referred to as a dynamic torque.
- This dynamic moment determines the dynamic acceleration of the internal combustion engine 2, wherein this dynamic torque can also be temperature-dependent and is typically determined according to the following equation.
- MkuppPart2 Jmot * wTgt, where
- Mkupp Mstart_eng ( ⁇ , ⁇ ) + Jmot * wTgt, wherein the dynamic torque is superimposed on the target clutch torque and provided by the electric motor 3.
- the desired clutch torque is limited to the dynamic torque, while the friction and compression torque is reduced or completely set to zero.
- the desired clutch torque includes only portions to set the desired target acceleration of the engine 2.
- the rotational speed N_Emot of the electric motor 4 rises in phase 2, in order to bring the combustion engine 2 along.
- the setting of the desired acceleration of the internal combustion engine 2 can be assisted by a control unit. It is important to ensure that the total clutch torque towards the end of phase 2, where the engine speed N_ICE approaches the electric motor speed N_Emot, is as small as possible, to an unnecessary
- the hybrid disconnect clutch 6 is fully closed. This can be realized once by using a ramp function in the control. Alternatively, however, a slip control is conceivable.
- the restarting functionality in a hybrid vehicle is optimized by making the activation of the internal combustion engine 2 dependent on its parking position in the first phase of the restart. This has the advantage that a safe restart is possible thereby and at the same time the subsequent acceleration behavior is clearly reproducible.
