Definitions

  • the invention relates to a method for starting a hybrid electric vehicle, a drive train for a hybrid electric vehicle, and a control device and a hybrid electric vehicle.
  • one of the electrical machines is often provided primarily as a starter generator and the second electrical machine is primarily provided as a traction machine.
  • the starter generator can, for example, be permanently connected to the internal combustion engine by a belt drive.
  • the combustion engine is connected to the traction machine via a clutch CO.
  • the traction machine in turn can be connected to a transmission by means of a further clutch C1.
  • ICE internal combustion engine
  • N_ICE_min a minimum speed of its crankshaft
  • VS_min a minimum speed solely by the traction machine when starting off.
  • VS_min is characterized by the fact that at this speed the transmission input speed (this is also the speed of the output side of clutch C1 has at least the value of N_ICE_min.
  • the invention is therefore based on the object of avoiding the problems mentioned when starting and driving off a hybrid electric vehicle.
  • the method according to the invention for starting relates to a hybrid electric vehicle having an internal combustion engine with a crankshaft and a first electric machine which is connected to the internal combustion engine.
  • the crankshaft of the internal combustion engine is detachably connected to a traction shaft of the vehicle via a first clutch.
  • the internal combustion engine is first switched off and the first releasable clutch is closed, as a result of which the crankshaft of the internal combustion engine is non-rotatably connected to the traction shaft.
  • the first electric machine provides a torque (TQ_SG) for starting the vehicle, which sets the crankshaft of the internal combustion engine in rotation and is transmitted to the traction shaft of the vehicle via the closed first clutch.
  • a torque is preferably provided by the first electrical machine (ie by the starter generator SG) which is higher than a loss torque (TQ_ICE_LOSS) which is required to rotate the crankshaft of the internal combustion engine (ICE).
  • TQ_SG_RES TQ_SG - TQ_ICE_LOSS.
  • the traction shaft for its part, is coupled to the output of the vehicle, for example via a gearbox and, if necessary, further clutches. Since the crankshaft is coupled to the abrasion via the traction shaft, the acceleration of the crankshaft is coupled to the acceleration of the vehicle. In particular, if the gear ratio remains the same, the increase in the rotational speed of the crankshaft can be proportional to the acceleration of the vehicle. This applies in particular to the beginning of the starting process, as long as the traction shaft is coupled to the output via a constant ratio. In this application, starting means accelerating the vehicle from a standstill.
  • the first electrical machine is a starter generator, for example, and is preferably permanently connected to the internal combustion engine, for example via a belt drive.
  • the belt drive thus allows a rotary motion of a rotor shaft of the starter generator to be transmitted to the crankshaft of the internal combustion engine, or vice versa.
  • the internal combustion engine is therefore dragged along from the start when the vehicle is accelerated. Since the CO clutch is closed from the start, no separate synchronization between the crankshaft and the traction shaft is required when starting the combustion engine. As a result, on the one hand, friction losses due to synchronization and/or current and load peaks, which can lead to voltage fluctuations in the vehicle electrical system, can be successfully avoided.
  • a further advantage of the invention is therefore lower demands on the stability of the vehicle electrical system than in conventional hybrid drives.
  • an additional torque is provided by at least one second electric machine (traction machine) to start the hybrid electric vehicle together with the resulting torque of the starter generator contributes to the traction of the vehicle and is coupled to the output.
  • a higher traction torque is available overall, namely the sum of the torque of the second electrical machine and the resulting torque of the starter generator for the output.
  • both electric machines, namely the starter generator and the traction machine both contribute torque to the traction of the vehicle at the same time.
  • the resultant torque for traction of the vehicle is thus the sum of the resultant torque from the first electrical machine and the (resultant) torque provided by the second electrical machine.
  • the second electrical (traction) machine can thus be dimensioned to be less powerful than in conventional hybrid drives according to the prior art. This can lead to lower hardware costs.
  • the traction shaft is preferably non-rotatably connected to the rotor of a second electrical machine and forms its rotor shaft.
  • the traction shaft is in turn detachably connected to an output shaft of the vehicle by means of a second detachable clutch (C1).
  • the output shaft leads, for example, as a transmission input shaft to a transmission. From there, the output is transmitted to the wheels of the vehicle.
  • the variant described here corresponds to a P0+P2 architecture.
  • the method according to the invention can also be used for other hybrid architectures, such as a P0+P3 or P0+P4 architecture, in which case one or more second electric traction machines can be located, for example, after the transmission (P3) or on the wheels (P4).
  • the clutch CO can advantageously be designed as a cheap, positive clutch or claw clutch.
  • the clutch C1 can also be designed as a positive clutch, a so-called claw clutch.
  • Jaw clutches have the advantage over friction clutches that they are less complex and less expensive.
  • the interconnected shafts cannot be synchronized by means of a dog clutch. The synchronization of the speeds for engaging must be done in a different way be ensured, for example by appropriate control of the traction machine and the combustion engine with crankshaft.
  • the first clutch CO is in the engaged, ie closed, state during the starting process when the internal combustion engine is switched off. This means that the crankshaft of the combustion engine is non-rotatably connected to the traction shaft at this point in time.
  • the internal combustion engine is started after the first acceleration from standstill of the vehicle when a speed threshold (v_VM_min) of the vehicle is exceeded. Since the internal combustion engine was dragged along from the start, no further synchronization is necessary.
  • the starting process is completed when the vehicle speed reaches or exceeds the value VS_min and fuel injection and combustion are initiated. After the combustion engine has been started, it can also contribute to traction through combustion. Because the speed of the internal combustion engine does not have to be adjusted by the starter generator to the speed of the traction shaft (or transmission input speed) and no engagement process is necessary, the starting process is accelerated overall.
  • the invention thus enables a starting process while the internal combustion engine is in unfired operation and the clutch CO is in the engaged state.
  • Additional advantages of the invention are an acceleration of the starting process, even in situations such as a “snapping start” and, moreover, emergency running properties if the clutch CO fails.
  • the object of the invention is also achieved by a drive train for a hybrid electric vehicle with an internal combustion engine with a crankshaft and a first electrical machine which is connected to the internal combustion engine.
  • the crankshaft of the internal combustion engine can be releasably connected to a traction shaft of the vehicle via a first clutch.
  • the traction shaft can in turn be coupled to an output of the vehicle.
  • the first electrical machine can be a starter generator, for example, which is permanently connected to the internal combustion engine, in particular by a belt drive.
  • the traction shaft is non-rotatably connected to a rotor of a second electrical machine, wherein the traction shaft can be releasably connected to an output shaft of the vehicle by means of a second clutch.
  • the first clutch and/or the second clutch can advantageously be designed as a form-fitting clutch (claw clutch).
  • the internal combustion engine is revved up comparatively slowly compared to the prior art. Since the crankshaft is coupled to the abrasion via the traction shaft, the acceleration of the crankshaft is coupled to the acceleration of the vehicle. In particular, the increase in the rotational speed of the crankshaft may be proportional to the acceleration of the vehicle. This applies in particular to the beginning of the starting process, as long as the traction shaft is coupled to the output via a constant ratio. Combustion engines in conventional hybrid drives are often not designed for this and vibration resonances could therefore occur.
  • the internal combustion engine is therefore preferably set up for slow revving. This can mean, for example, that it has a corresponding mass flywheel that is designed for slow revving.
