Definitions
- TITLE CONTROL OF THE TORQUE PROVIDED BY A HYBRID GMP OF A LAND VEHICLE DURING AN UPWARD GEAR CHANGE OF AN AUTOMATED GEARBOX
- the invention relates to land vehicles comprising a hybrid powertrain (or GMP) and an automated gearbox, and more specifically to the control of the torques to be provided by the driving machines of such GMPs during an upward gear change (from n to n+1).
- GMP hybrid powertrain
- Certain land vehicles possibly of the automobile type, include a hybrid powertrain (or GMP) and an automated gearbox (possibly with a dual clutch (or DCT (“Dual Clutch Transmission”)).
- GMP hybrid powertrain
- DCT Dual Clutch Transmission
- hybrid GMP means a GMP comprising a first thermal drive machine capable of providing a first torque to the drive wheels, and at least one second non-thermal drive machine capable not only of providing a second torque to the drive wheels, forming with the first torque a total torque (or “wheel torque”), but also of recovering torque in its vehicle.
- the second non-thermal driving machine is generally an electric machine associated with a battery or a fuel cell (for example hydrogen). But this is not an obligation.
- an automated gearbox and therefore with at least two clutches
- it proceeds in two phases. In a first phase it prepares the two clutches concerned to transfer the total torque provided by the GMP, then in a second phase it actually performs the transfer of the total torque between the two clutches.
- a disadvantage of this mode of upshifting lies in the fact that the torque input made by the first drive machine is not fast enough with regard to the dynamics required for the torque transfer phase, unlike the torque input made by the second drive machine which is very fast. Consequently, when the second drive machine is not able to provide the torque input, the total torque supplied to the primary shaft upstream of the clutches is not sufficient to compensate for the change in gear ratio, and therefore there is a loss of torque at the wheels during the upshift, which is detrimental to the quality of this change and is felt by the passengers of the vehicle.
- the invention therefore aims in particular to improve the situation.
- a powertrain comprising first and second thermal and non-thermal drive machines respectively and capable of providing for drive wheels respectively first and second torques together forming a total torque, the second drive machine also being capable of recovering torque, and
- an automated gearbox with at least two clutches, and capable of receiving the total torque and of carrying out a change, from an nth gear having an nth gear ratio to an (n+1)th gear having an (n+1)th gear ratio lower than the nth gear ratio, by carrying out a first phase in which it prepares the clutches concerned to transfer the total torque to each other, then a second phase in which the clutches transfer the total torque to each other.
- This control method is characterized by the fact that it comprises a step in which during the entire first phase, when the second drive machine cannot provide a second torque, the first drive machine is required to provide, in addition to its first torque, an additional torque at least partially compensating for a loss of torque induced by the change in gear ratio by generating a request for torque recovery by the second drive machine increased by this additional torque.
- the first drive machine when the second drive machine is not capable of providing torque, the first drive machine provides additional torque in an anticipatory manner in the first phase, and therefore the total torque provided upstream of the clutches of the gearbox during the second phase is now sufficient to compensate for the change in gear ratio, which significantly improves the quality of the upshift.
- control method according to the invention may include other characteristics which may be taken separately or in combination, and in particular: [0015] - in its step, the first driving machine can be required to provide additional torque fully compensating for the loss of torque;
- the additional torque can vary in a linearly increasing manner
- the additional torque can vary in an increasing parabolic manner.
- the invention also provides a computer program product comprising a set of instructions which, when executed by processing means, is capable of implementing a control method of the type presented above, in a land vehicle comprising, on the one hand, a powertrain comprising first and second respectively thermal and non-thermal drive machines and capable of providing for drive wheels respectively first and second torques together forming a total torque, the second drive machine also being capable of recovering torque, and, on the other hand, an automated gearbox, with at least two clutches, and capable of receiving the total torque and of carrying out a change, from an nth gear having an nth gear ratio to an (n+1)th gear having a (n+1)th gear ratio lower than the nth gear ratio, by carrying out a first phase in which it prepares the clutches concerned to transfer the total torque to each other then a second phase in which the clutches transfer the total torque to each other, to control the torque total provided during gear change.
- the invention also proposes a control device intended to equip a land vehicle comprising:
- a powertrain comprising first and second thermal and non-thermal drive machines respectively and capable of providing for drive wheels respectively first and second torques together forming a total torque, the second drive machine also being capable of recovering torque, and [0022] - an automated gearbox, with at least two clutches, and capable of receiving the total torque and of carrying out a change, from an nth gear having an nth gear ratio to an (n+1)th gear having an (n+1)th gear ratio lower than the nth gear ratio, by carrying out a first phase in which it prepares the clutches concerned to transfer the total torque to each other, then a second phase in which the clutches transfer the total torque to each other.
- This control device is characterized by the fact that it comprises at least one processor and at least one memory arranged to carry out the operations consisting, during the entire first phase, when the second driving machine cannot provide a second torque, in triggering an imposition on the first driving machine to provide, in addition to its first torque, an additional torque at least partially compensating for a loss of torque induced by the change in gear ratio by generating a request for torque recovery by the second driving machine increased by this additional torque.
- the invention also provides a land vehicle, possibly of the automobile type, and comprising:
- a powertrain comprising first and second thermal and non-thermal drive machines respectively and capable of providing for drive wheels respectively first and second torques together forming a total torque, the second drive machine also being capable of recovering torque,
- an automated gearbox with at least two clutches, and capable of receiving the total torque and of carrying out a change, from an nth gear having an nth gear ratio to an (n+1)th gear having an (n+1)th gear ratio lower than the nth gear ratio, by carrying out a first phase in which it prepares the clutches concerned to transfer the total torque to each other, then a second phase in which the clutches transfer the total torque to each other, and
- FIG. 1 schematically and functionally illustrates an exemplary embodiment of a land vehicle comprising a control device according to the invention, and a transmission chain with automated gearbox and hybrid GMP and associated with a supervision computer,
- FIG. 2 schematically and functionally illustrates an exemplary embodiment of a supervision calculator comprising an exemplary embodiment of a control device according to the invention
- FIG. 3 schematically illustrates an example of an algorithm implementing a control method according to the invention.
- the invention aims in particular to propose a control method, and an associated DC3 control device, intended to allow control, in a land vehicle V comprising a hybrid powertrain (or GMP) and an automated gearbox BV, of the total torque supplied by this GMP during an upward gear change (n to n+1).
- GMP hybrid powertrain
- BV automated gearbox
- the land vehicle V is of the automobile type.
- it is a car, as illustrated in FIG. 1.
- the invention is not limited to this type of land vehicle. It in fact concerns any type of land vehicle comprising a hybrid GMP transmission chain and automated gearbox. Thus, it concerns in particular utility vehicles, campers, minibuses, coaches, trucks, motorcycles, road machinery, construction machinery, agricultural machinery, leisure machinery (snowmobile, kart), and tracked machinery, for example.
- the GMP is thermal and electric. It therefore comprises at least a first thermal drive machine MM1 and at least one second electric drive machine MM2.
- the invention is not limited to this type of GMP. It in fact concerns all GMPs comprising first and second drive machines, respectively thermal and non-thermal, and capable of providing for drive wheels respectively first and second torques forming together a total torque.
- the second electric motor MM2 is associated with at least one rechargeable battery BP (called main or traction). But it could be associated with a fuel cell (for example hydrogen).
- the automated gearbox BV is a dual-clutch gearbox (or DCT).
- DCT dual-clutch gearbox
- the invention is not limited to this type of automated gearbox. It in fact concerns all automated gearboxes comprising at least two clutches.
- the transmission chain could also allow a four-wheel drive (or 4x4) or 4x2 mode.
- FIG. 1 schematically shows a (land) vehicle V comprising a hybrid GMP transmission chain (here thermal and electric) and automated BV gearbox, a supervision computer CS, a rechargeable main (or traction) battery BP, and a control device DC3 according to the invention.
- the transmission chain also comprises, here, a drive shaft AM, a first coupling device DC1, a second coupling device DC2, and a transmission shaft AT.
- the first (thermal) motor machine MM1 comprises a crankshaft (not shown) which is fixedly secured to the motor shaft AM in order to drive the latter (AM) in rotation.
- This first motor machine MM1 is capable of operating according to a first speed in order to provide a first couple d defined by a first motor instruction, for example determined by the CS supervision calculator.
- the first driving machine MM1 is capable of being coupled to the gearbox BV, via at least the first coupling device DC1.
- the latter (DC1) is capable of delivering a torque from the first torque c1, in particular for at least one train T1 of driving wheels, when it is in its coupled position and therefore when it couples the thermal driving machine MM1 to the gearbox BV.
- the first coupling device DC1 may be a hydraulic circuit clutch. But it could be of another type.
- the train T1 can be located in the front part PW of the vehicle V. It is preferably, and as illustrated, coupled to the transmission shaft AT via a differential (here front) DV. But in a variant this train T1 could be the one referenced T2 which is located in the rear part PRV of the vehicle V.
- the second (non-thermal (here electric)) driving machine MM2 is capable of providing for the driving wheels of the vehicle V a second torque c2 defined by a second driving instruction, for example determined by the supervision computer CS.
- the second driving machine MM2 is, here, installed between the first coupling device DC1 and the gearbox BV. It therefore provides a second torque c2 for the train T1. But in a variant it could provide a second torque c2 for the train T2.
- the first coupling device DC1 when the first coupling device DC1 has been placed in its coupled state (or completely closed) and the first driving machine MM1 is operating (and therefore at a first non-zero speed to provide the first torque c1), the first coupling device DC1 delivers a torque which is added to a possible second torque c2 provided, upstream of the gearbox BV, by the second driving machine MM2 when it is supplied (here) with electrical energy (here) by the battery main BP.
- the first coupling device DC1 has been placed in its decoupled state (or fully open) only the second driving machine MM2 can provide a second torque c2 upstream of the gearbox BV in a purely electric driving phase.
- the second driving machine MM2 is also capable of recovering a third torque c3 in the vehicle V. This is particularly the case here in a regenerative (or regenerative) braking phase, and in this case the third recovered torque c3 can be used to recharge the main battery BP associated with the second driving machine MM2. But the recovery can also be done on a part of the first torque c1 provided by the first driving machine MM1, as will be seen later.
- the main battery BP may be of the cellular type.
- it comprises electrical energy storage cells, possibly electrochemical (such as for example lithium-ion (or Li-ion) or Ni-Mh or Ni-Cd type cells).
- this main battery BP may be of the 450 V type. But this is not an obligation. Indeed, it could alternatively be of the 48 V or 600 V type, for example.
- the gearbox BV being automated (and therefore comprising at least two clutches), when it has to carry out a change from an nth gear having an nth gear ratio d n to an (n+1)th gear having an (n+1)th gear ratio d n +i lower than the nth gear ratio d n (i.e. d n > d n +i), it proceeds in two phases. In a first phase it prepares the two clutches concerned to transfer the total torque and which is provided by the GMP, then in a second phase it actually carries out the transfer of the total torque and between the two clutches.
- the transmission chain also comprises a second coupling device DC2 installed downstream of the first coupling device DC1 and electric motor MM2 and upstream of the gearbox BV. But this is not an obligation.
- the first coupling device DC1, the second coupling device DC2, the electric motor MM2 and the gearbox BV are part of a gearbox assembly EBV. But this is not an obligation.
- the invention proposes in particular a control method intended to allow control of the total torque and which is provided by the GMP during an upward gear change (n to n+1) in the BV gearbox.
- This (control) method can be implemented at least partially by the control device DC3 (illustrated at least partially in FIGS. 1 and 2) which comprises for this purpose at least one processor PR1, for example a digital signal processor (or DSP), and at least one memory MD.
- This control device DC3 can therefore be produced in the form of a combination of electrical or electronic circuits or components (or “hardware”) and software modules (or “software”). For example, it can be a microcontroller.
- the MD memory is RAM in order to store instructions for the implementation by the processor PR1 of at least part of the control method.
- the processor PR1 may comprise integrated (or printed) circuits, or several integrated (or printed) circuits connected by wired or wireless connections.
- An integrated (or printed) circuit is understood to mean any type of device capable of performing at least one electrical or electronic operation.
- the control device DC3 is part of the supervision computer CS. But this is not obligatory. Indeed, the control device DC3 could comprise its own dedicated computer, which can then be coupled to the supervision computer CS, or could be part of another computer embedded in the vehicle V and providing at least one other function, for example.
- the (control) method according to the invention comprises a step 10-20 which is implemented each time an upward gear change (n to n+1) must be carried out in the gearbox BV.
- Step 10-20 of the method comprises a substep 20 in which, during the entire first phase of an upward gear change, when the second driving machine MM2 cannot provide a second torque c2, the first driving machine MM1 is required (for example, the control device DC3 triggers the requirement) to provide (supply) in addition to its first torque c1 an additional torque ca by generating a torque recovery request by the second driving machine MM2 increased by this additional torque ca.
- the latter (ca) is determined (for example, by the control device DC3) so as to at least partially compensate for the loss of torque pc which is induced by the change in gear ratio (from d n to d n +i, with d n > d n +i).
- the first drive machine MM1 provides additional torque ac in an anticipatory manner in the first phase (torque transfer preparation), and therefore the total torque which is provided to the primary shaft AP upstream of the clutches of the gearbox BV during the second phase (torque transfer) is now sufficient to compensate for the change in gear ratio. There is therefore no longer any risk of ending up with a loss of torque at the wheels during the second phase of an upshift, which significantly improves the quality of the upshift.
- the additional torque ca which is recovered by the second driving machine MM2 during the first phase (and therefore which constitutes a third torque c3), can, for example, be (here) converted by the second MM2 driving machine in electric current allowing the main BP battery to be recharged.
- step 10-20 may include a sub-step 10 in which one (for example the control device DC3) can determine the additional torque ca to be provided by the first drive machine MM1 as a function of the torque loss pc induced by the change in gear ratio.
- one for example the control device DC3
- the control device DC3 can determine the additional torque ca to be provided by the first drive machine MM1 as a function of the torque loss pc induced by the change in gear ratio.
- step 20 of step 10-20 it is possible to impose (for example the control device DC3 can trigger the imposition) on the first driving machine MM1 to provide (to provide) an additional torque ca which fully compensates for the loss of torque pc. But this is not an obligation. Indeed, the additional torque ca could only partially compensate for the loss of torque pc. For example, it is possible to envisage choosing partial compensation when an economical driving mode has been selected in the vehicle V.
- the additional torque ca (partially or totally compensating for the loss of torque pc) can be determined in sub-step 10 (for example by the control device DC3).
- sub-step 20 of step 10-20 it is possible to impose (for example the control device DC3 can trigger the imposition) on the first driving machine MM1 to provide (to provide) an additional torque ca which is variable between two values.
- This is then referred to as filtering of the additional torque ca carried out for example by the control device DC3.
- the additional torque ca preferably varies in an increasing manner between the two aforementioned values, in order to allow the first driving machine MM1 to gradually increase the first torque c1 which it provides.
- the two values between which the additional torque ca must vary can be determined in sub-step 10 (for example by the control device DC3).
- the determined additional torque ca could have a single value (function of the partial or total compensation of the loss of torque pc).
- the first driving machine MM1 is forced to immediately provide a first torque c1 increased by the value of the additional torque ca.
- step 20 of step 10-20 when the additional torque ca must vary, its variation can be done in a linear increasing manner. But in an alternative embodiment, its variation could be done in a parabolic increasing manner (or according to any other faster growing function (of type x n with n > 2)).
- the supervision computer CS (or the computer of the control device DC3) can also comprise a mass memory MM1, in particular for storing each loss of torque pc and each additional torque ca associated with the latter (pc), as well as any intermediate data involved in all its calculations and processing.
- this supervision computer CS (or the computer of the control device DC3) can also comprise an input interface IE for receiving each loss of torque pc, for using it in calculations or processing, possibly after having formatted and/or demodulated and/or amplified it, in a manner known per se, by means of a digital signal processor PR2.
- this supervision computer CS (or the computer of the control device DC3) can also comprise an output interface IS, in particular for delivering each message containing the determined additional torque ca.
- the invention also proposes a computer program product (or computer program) comprising a set of instructions which, when executed by processing means of the electronic circuit (or hardware) type, such as for example the processor PR1, is capable of implementing the control method described above to control the total torque in the vehicle V and which is provided during an upward gear change (n to n+1).
