Definitions
- a method of driving a hybrid vehicle engine device
- the invention relates to the field of motorizations of vehicles. It relates more particularly to so-called hybrid engines, comprising an electromechanical chain and an internal combustion engine. Even more specifically, it relates to a method of managing a hybrid vehicle, as well as the associated device.
- a motorization system is said to be hybrid in that it is composed of two different energy sources.
- These energy sources may be, for example and in the most usual case, an internal combustion engine (“ICE”) unit and an electric propulsion unit, which then generally comprises a electrical energy storage system (SSEE) such as batteries or supercapacitors.
- ICE engine an internal combustion engine
- SSEE electrical energy storage system
- Hybrid systems provide autonomy comparable to vehicles with a conventional engine type internal combustion engine, while reducing emissions and consumption.
- the hybrid combination of a vehicle is particularly considered, by a mechanical chain (ICE engine + transmission) and an integrated electromechanical chain.
- the constituents of this electromechanical chain are essentially composed of electric machines controlled by a motor or generator connected by a SSEE through electrical converters for controlling these electrical machines. These electric converters may or may not be integrated with electrical machines. For the sake of simplification, we will consider the electric converter controlling the electric machine in engine or generator mode as a single entity that will be called simply electric machine.
- FIGS. 1 to 3 three main architectural families are distinguished for the current hybrid vehicles, illustrated here in FIGS. 1 to 3.
- the double lines represent the mechanical power transmission lines, and the simple lines power transmission lines.
- ICE internal combustion engine
- SSEE 3 a first architecture, called “series” (see Figure 1), an internal combustion engine (ICE) 1 is connected to a generator 2 which produces electricity.
- ICE internal combustion engine
- This electrical energy is stored in a SSEE 3 and then used to drive one or more electrical machines 4, which provide the power necessary to drive the wheels 5, via a differential 6, to propel the vehicle.
- an ICE thermal engine 1 associated with a transmission 7, on the one hand, and an electric machine 4, on the other hand, are mechanically connected to the wheels 5 of the vehicle, through a differential 6.
- the electromechanical chain then participates in accelerations, energy recovery and possibly in the ribs and at startup.
- Such a parallel hybrid system often gives a good performance, when the additional torque brought by the electric machine 4 in engine mode corresponds to the optimized zone (speed, torque) of the engine ICE 1.
- the energy efficiency of the parallel hybrid system is no longer optimized.
- the wheels 5 of the vehicle are linked to the ICE engine 1 through the different stages of mechanical gear ratios and the optimized adjustment of the engine speed, among the speed stages proposed by the transmission, is not possible.
- a third architecture is a particular construction of hybrid systems that allows to switch from one mode (parallel or series) to another, gradually or not.
- an ICE motor 1 is capable of driving the wheels 5 through a mechanical energy distributor 8 and a differential 6.
- the mechanical energy distributor 8 is in turn connected to a generator 2, that transforms some of the energy ICE engine 1 mechanical energy, which is stored in a SSEE 3.
- One or more electric motors 4 also drive the wheels 5 through the differential 6.
- the mechanical energy distributor 8 distributes the mechanical power at will in two streams, thanks to an epicyclic gear train.
- a first part of this mechanical power is used to directly drive the wheels 5, and the other part of this mechanical power is converted into electricity via the generator 2 to power the electric motor 4 or load the SSEE 3.
- This architecture takes advantage of the possibility of controlling the torque and the engine speed cleverly distribute the power flows without benefiting from the total independence of these two variables.
- a torque-speed dependence relation on the three axes of the planetary gear train does not allow to choose a torque and a regime which corresponds to a point of operation of the fully optimized ICE.
- the system controls the two drive sources 1, 4 to obtain a good performance of the ICE engine 1 according to the driving conditions.
- This power distribution structure is found in particular on hybrid vehicles most widely marketed today.
- the present invention therefore aims to provide a device responding to the problem described above namely the reduction of fuel consumption.
- a second object of the invention is to be simple and inexpensive to implement.
- the invention is directed to a device for motorizing a hybrid land vehicle, said device comprising a first mechanical power transmission line comprising an internal combustion engine connected to a first machine electrical, a second mechanical power transmission line comprising a second electric machine capable of driving rotating wheels of the vehicle, the two electric machines, controllable as a motor or generator, being connected to an electrical energy storage system,
- the device further comprising:
- control means for these various elements connected to a computer
- the consumption of the internal combustion engine in parallel mode defined as a mode in which the shaft of the internal combustion engine drives the wheels via different mechanical gear members, the two mechanical transmission lines being connected to the through the coupling device, that is to say, the consumption of said internal combustion engine at a given moment without electrical assistance and,
- an equivalent consumption calculated from the optimal consumption of the internal combustion engine to which are added the losses due to the activation of the electric chain of the serial mode defined as a mode in which the traction of the vehicle is provided by the second electric machine alone, the two mechanical transmission lines being separated by the coupling device, an intermittent use of the internal combustion engine to recharge the electrical energy storage system regularly to meet a continuous demand power at the wheels.
- the all-or-nothing coupling-decoupling system is a clutch-type device which makes it possible to completely separate, from a mechanical point of view, the two mechanical power transmission lines.
- This decoupling coupling system can also be replaced if necessary by the conventional clutch associated with the gearbox.
- the device also comprises a gearbox disposed on one of the mechanical power transmission lines.
- This gearbox can be associated with its own conventional clutch system or use the coupling-decoupling system used in this case as a clutch box.
- This arrangement conventionally makes it possible to use the internal combustion engine at its optimum operating point at several speeds of the vehicle.
- the two electrical machines are sized for a nominal power of the order of 10 to 30 kW.
- This power is roughly half the power of electrical machines used in the prior art for comparable reductions in fuel consumption.
- the electrical energy storage system is of the fast charging and discharging type.
- the invention aims, in a second aspect, at a method for controlling a hybrid vehicle power device as described, the method consisting in using at least two distinct modes of architecture:
- the intermittent recharging of the SSEE by the ICE takes place through the first electric machine.
- the transition from one mode to the other is determined by a comparison step between the consumption of the internal combustion engine in parallel mode (that is to say, the consumption of said engine internal combustion at a given instant without electric assistance), and the equivalent consumption calculated from the optimal consumption of the internal combustion engine to which are added the losses due to the activation of the electric chain of the series mode.
- the computer uses the series mode with intermittent use of the internal combustion engine.
- the computer controls the various members of the electromechanical chain for intermittent use of the internal combustion engine.
- the computer uses the parallel mode, and the internal combustion engine is used alone to drive the wheels.
- the computer uses the parallel mode, and one or both electrical machines are used in motor mode to provide additional torque on the transmission shaft to drive the wheels together with the internal combustion engine. It is understood that the invention proposes to optimize the management method of a series / parallel system known until now by allowing a connection:
- the ICE engine loads the SSEE through the first electrical machine (used in generator mode), at its optimum operating point, that is to say at its operating point (speed, torque) corresponding to the better (ie the lowest) fuel consumption while the second electric machine (used in engine mode) delivers to the wheels the power demanded by the driver.
- This mode of operation necessarily induces rapid alternating phases of operation of the ICE engine (load of the SSEE at the optimum operating point of the ICE) with stopping phases of the ICE motor (SSEE discharge).
- the idea is therefore to use the ICE motor intermittently (according to an "all or nothing" operating mode) in its optimal operating zone, ie in the operating zone corresponding to the fuel consumption. lower.
- FIG. 5 a schematic view of a serial / parallel hybridization device according to the invention.
- Figure 5 illustrates in a simplified manner the elements of a motorization device according to the invention. It finds its place in a land vehicle such as a car, hybrid type of motorization.
- the device comprises in the first place an internal combustion engine 1, of gasoline type in the present example in no way limiting.
- an ICE engine 1 is known per se and is therefore not detailed further here.
- This first electric machine 9 The functions of this first electric machine 9 are:
- the device also comprises a second electrical machine 4, which is also connected to the SSEE 3.
- This second electric machine 4 When used in motor mode:
- the purpose of the invention is not a power distribution between the ICE engine 1 and the electric generator motors 4, 9 but an optimized use of the ICE engine 1 with possible occasional electrical assistance by these engines if necessary, both Generating motors 4, 9 can be sized at a relatively low power, for example 10 to 30 kW. This is different from the prior art, in which a 50 kW electric motor and a 30 kW generator are typically used.
- the second electrical machine 4 is connected to the wheels 5 of the vehicle via a second mechanical transmission line 13 which comprises a transmission member 11, composed of a gearbox and possibly a clutch device. box, and a differential 6.
- the function of the gearbox is to allow both the ICE engine 1 and the second electric machine 4 to operate at satisfactory torques and speeds, corresponding to their range or optimized operating zone.
- the gearbox is of a type known to those skilled in the art.
- the device further comprises, on the mechanical power transmission line of the ICE engine 1, downstream of the first electrical machine 9, and upstream of the second electrical machine 4, a clutch type device 10 for coupling-decoupling.
- This clutch 10 is the element that allows the passage from serial mode to parallel mode.
- This clutch is of a type known to those skilled in the art.
- the SSEE 3 is connected to the two electrical machines 4, 9.
- the SSEE 3 serves as a buffer stage, on the one hand by quickly storing the energy supplied by the ICE engine 1 when it operates at its optimal point, during its active phase, and secondly by delivering the required continuous power to the wheels 5.
- the SSEE 3 makes it possible to recover a portion of the kinetic energy of the vehicle during the deceleration phases
- the SSEE can provide additional energy during the acceleration phases.
- SSEE 3 can be loaded and unloaded very quickly, so that the ICE 1 engine does not have the time to cool between two operations.
- the SSEE 3 must therefore be of small capacity (a few tens of Wh), compared to the prior art, which is very advantageous in terms of cost and embedded weight.
- the device also comprises a computer 14 connected to the main elements of the motorization described, in particular the two electrical machines 4, 9, the SSEE 3, the ICE motor 1, the coupling-decoupling system 10 and the transmission member 11.
- the device as seen in FIG. 5, has several differences with respect to the prior art of hybrid architectures, and notably:
- a transmission member 1 comprising a gearbox and possibly a box clutch device.
- the nominal powers of the two prior art generator engines are designed to provide sufficiently large additional powers to the ICE engine (between 30% and 50% of the total available power) to enable ICE 1 to to be reduced accordingly.
- the epicyclic gear train of the energy distributor 8 never makes it possible to completely eliminate the transfer of mechanical energy to the electrical generation chain, and permanently generates a loss of energy. yield, up to 20%.
- the ICE engine meanwhile does not undergo or little power reduction can remain identical to that of a comparable conventional vehicle.
- the dimensions of the heat sink elements necessary for the proper functioning of the electromechanical chain components are proportional to the nominal power they must transfer and will therefore be significantly reduced.
- the invention particularly aims to use the electric assistance provided by the electrical machines 4, 9 wisely.
- the driving method of a hybrid architecture according to the invention consists in using two modes: a first mode called “parallel”, and a second mode called “intermittent series”.
- the parallel mode is obtained when the clutch 10 is in the engaged position.
- the mechanical connection is connected between the ICE engine 1 and the wheels 5 via the various gear reduction members of the transmission devices.
- the ICE engine 1 drives the wheels 5, with or without the electric assistance (assistance only during strong acceleration phase) of the electrical machines 4, and / or 9. It is important to note that in this case , the ICE engine 1 is then not used to charge the SSEE 3.
- the two electrical machines 4 and / or 9 can recover the kinetic energy recoverable from the vehicle during the deceleration phases (generator mode).
- the clutch 10 In the intermittent serial mode, the clutch 10 is in the disengaged position. The mechanical connection is thus disconnected between the ICE engine 1 and the wheels 5.
- the wheels are driven by the second electric machine 4.
- the ICE engine 1 is used intermittently,
- the computer 14 manages the stopping and starting phases of the injection system of the ICE synchronously with respect to the control of the two electrical machines. Both electrical machines have different functions. Firstly in the active phase of the ICE engine, the first electrical machine 9 drives the ICE engine for startup (motor mode). Then when the ICE is started, the computer 14 authorizes the fuel injection system at the ICE so that the latter is in the optimal operating zone (rpm, torque) and controls the electric machine 9 in mode generator to transmit the energy of the ICE engine 1 to the SSEE that is charging.
- the optimal operating zone rpm, torque
- the computer 14 controls the stopping of the fuel injection system of the ICE and the electric machine 9 still in generator mode contributes to the deceleration of the ICE engine by recovering part of the kinetic energy of the moving parts of the ICE engine.
- the electric machine 9 is also stopped.
- the demand for power to the wheels is entirely provided by the SSEE which discharges through the second electric machine 4. This operates in this case either in motor mode (traction of the vehicle) or in generator mode (deceleration of the vehicle).
- control method according to the invention also allows hybrid standard functions, of assistance type of the two electric generator motors 4, 9 on the wheels 5 during strong accelerations (function known as “boost”), braking energy recovery by the two electric motors-generators 4, 9, and automatic shutdown of the ICE engine 1 at each stop of the vehicle (function known as “stop & start “or” stop & go “).
- the method according to the invention comprises a comparison step between the consumption of the ICE engine 1 in parallel mode (that is to say, the consumption of the ICE engine 1 at a given instant without electrical assistance), and the optimal consumption of the ICE 1 engine to which are added the losses due to the activation of the electric chain of the serial mode.
- the ICE motor 1 when the consumption of the ICE motor 1 in parallel mode is greater than the equivalent consumption of the set "ICE (optimal) + losses of the electric chain in series mode", then the ICE motor 1 operates in series mode so intermittent. That is, whether it is operating at its optimum operating point for charging the SSEE 3, or that it is stopped. In these two cases corresponding to the intermittent series mode, the second electrical machine 5 alone ensures the transmission of power to the wheels.
- the graphical representation of this function is illustrated in FIG. 4, in which the axes represent, in abscissas, the engine speed in revolutions / minute, in the ordinate the engine torque (in Nm).
- the closed curves IC then represent isotower lines of the motor, included in the present non-limiting example, between 250 g / kWh and 550 g / kWh. In other words, all the points corresponding to the same consumption are connected together to constitute "iso-consumptions" in the plane (torque regime) of the ICE engine.
- the optimal operating zone of the ICE engine is then, as understood, the zone included in the closed curve IC 2 so and groups together the operating points of the ICE engine whose consumption is equal to 250 g / kWh.
- the graph also illustrates, by the high LF curve, the limit of the operating range of the internal combustion engine.
- the second family of curves P corresponds to the power delivered by the engine in kvV, for each pair and number of revolutions / minute. Curves P are in the present example from 10 to 160 kW. The curve P 30 corresponding to the value 30 kW is here indicated in dotted lines.
- this point of consumption remains on average equal to 250 g / kWh because the electromechanical chain is not activated and no electrical loss comes degrade this performance.
- the operating point of the ICE must take into account the losses generated by the use of the electromechanical chain, that is to say about 20%.
- the power of the ICE to compensate for the losses must be increased accordingly, which leads to an equivalent consumption of the ICE 1 engine around 300 g / kWh.
- the ICE engine 1 runs near the ideal consumption point, for example at 280 g / KWh (point F2). Indeed it is useless to force the engine to run at 250 g / kWh (F1 point) and to solicit the electromechanical chain, since this equates to an average equivalent consumption of 300 g / kWh, higher than that of the starting point (280 g / kWh). It is therefore preferable for this point to remain in parallel mode, ie to drive the wheels 5 directly with the ICE engine 1.
- the operating point of the ICE engine 1 is equivalent to a consumption of 360 g / kWh (point F3 in FIG. 4), ie far from the optimal consumption of 250 g / KWh (point F1), it becomes interesting to switch to intermittent serial mode.
- the average equivalent consumption of the ICE motor then becomes that of the optimum point increased losses of the serial link is 300 g / KWh, (point F1) and it remains however lower than the initial consumption (360 g / kWh).
- the wheels 5 are then driven by the second electric machine 4.
- the stops of the ICE engine 1 are necessary so as not to overload the SSEE 3 which is of low capacity, but they must be short-lived so as not to not allowing the ICE 1 engine to cool too much, which could degrade the combustion quality of the ICE engine and thus contribute to increasing pollutant emission rates
- the power required for the traction of the wheels must be compatible with the available power of the SSEE 3 and the second electric machine 4.
- the average power demanded from the wheels must be lower than the peak power delivered by the ICE motor during the load phases of the SSEE, ie 30 kW in our example.
- the intermittent serial mode (clutch disengaged) makes it possible to improve the overall consumption of the vehicle for the efficiency points of the ICE engine 1 greater than 300 g / kWh, and for a traction power of less than 30 kW in this example.
- FIG. 4 Considering the particular case of a transfer power of 30 kW, the points concerned are thus, in FIG. 4, below the iso-power curve 30 kW, and below the insulation curve. consumption of 300 g / kWh (ie 250 g / kWh + 20%). They are represented by a hatched area in FIG. 4, corresponding to the present example provided here by way of no limitation. It is obvious that at these power levels (below 30 kW in our example), the high engine speeds will preferably be reduced by the play of the different stages of the transmission, at much lower speeds thus limiting the hatched area of the Figure 4 at relatively low engine speeds.
- This zone corresponds to an operation of the ICE engine in low load and low speed, that is to say mainly to a city cycle, which represents the vast majority of the cases of use of vehicles of automobile type. It is understood that the computer 14 proceeds at regular intervals to the comparison of consumptions in accordance with what has just been described, and then determines the operating mode used. It then controls the engagement or disengagement of the clutch 10 accordingly.
- the computer 15 controls the operation of the electrical machines 4, 9 in motor or generator mode.
- the computer 14 uses the intermittent serial mode (disengaged clutch), with the ICE engine 1 used in all or nothing mode in its optimum operating zone for charging the SSEE 3, and the wheels 5 driven by the second electric machine 4.
- the computer 14 uses the parallel mode (engaged clutch), with the ICE motor 1 used continuously to directly drive the wheels via the transmission members.
- the presence of the gearbox 11 contributes to getting closer to the optimal operation of the ICE engine.
- the computer 14 uses the parallel mode (engaged clutch), with the ICE motor 1 used continuously to directly drive the wheels, the two electrical machines 4, 9 can then also be used in motor mode to increase the power applied to the wheels 5.
- the computer 14 retains the previously engaged mode (series, or parallel). Part of the kinetic energy of the vehicle is recovered in the SSEE, either by the second electrical machine 4 (series mode) or by one or two electrical machines 4, 9 (parallel mode) the machines are then used as generators.
- a first advantage is a reduction in fuel consumption higher than the serial / parallel hybridization system of the prior art.
- the device requires only a small capacity battery which reduces the cost of said battery and its size in the vehicle.
- the device allows the use of relatively low power electrical machines, because the electrical assistance is requested preferentially only during low loads.
- these elements are then of low cost and reduced size.
- the coupling-decoupling system 10 may possibly be replaced by the existing box clutch system of the transmission member. Management and control between the different modes are simple.
