Definitions
- TITLE CONTROL OF RECUPERATIVE BRAKING MODES IN A LAND VEHICLE WITH SPEED CONTROL FUNCTION
- the invention relates to land vehicles comprising a powertrain (or GMP) capable of recovering regenerative braking torque and at least one speed control function capable of controlling their speed, and more precisely the control of regenerative braking modes in such vehicles.
- a powertrain or GMP
- GMP powertrain
- Certain land vehicles possibly of the automobile type, include:
- a powertrain capable of providing drive wheels with a torque which is a function of a torque setpoint and greater than or equal to a first minimum torque
- an accelerator pedal having a percentage of depression from which the torque setpoint is defined, the latter being greater than or equal to a second minimum torque which is strictly greater than the first minimum torque
- a disadvantage is that currently the maximum regenerative braking torque that can be recovered by a speed control function is equal to the second minimum torque which corresponds to a percentage of zero depression (0%) of the accelerator pedal and which is strictly greater than the first minimum torque for reasons of driving pleasure and safety. As a result, the level of deceleration that can be obtained is relatively low and therefore the time required to comply with the speed instruction is relatively long.
- the deceleration level is really low when the driver of the vehicle has selected a first regenerative braking mode from among first and second regenerative braking modes allowing the recovery of regenerative braking torques having first and second levels respectively, the first level being lower than the second level (here we are talking about absolute values).
- first level the low level of the deceleration that can be obtained thanks to the recovery of a low regenerative braking torque (first level)
- first level forces the speed control function to very frequently resort to the vehicle's braking system when going downhill. Consequently, a large part of the braking energy is dissipated in the brakes to no avail, even though it could have been at least partially used to recharge the vehicle's rechargeable battery and thus increase the vehicle's range in terms of mileage.
- the invention therefore aims in particular to improve the situation.
- a powertrain capable of providing first and second selectable regenerative braking modes and making it possible to recover in the vehicle regenerative braking torques having first and second levels respectively, the first level being lower than the second level.
- This control method is characterized by the fact that it comprises a step in which, when the first regenerative braking mode is selected, and when a target acceleration required by the speed control function is less than a potential minimum acceleration that can be ensured by the powertrain in the first regenerative braking mode, the use of the second regenerative braking mode is imposed to comply with the speed setpoint.
- control method according to the invention may include other characteristics which may be taken separately or in combination, and in particular:
- 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 and comprising, on the one hand, an accelerator pedal, on the other hand, a speed control function capable, in the event of activation, of controlling a current speed of the vehicle as a function of a speed setpoint, and, on the other hand, a powertrain capable of providing first and second selectable regenerative braking modes and making it possible to recover in the vehicle regenerative braking torques having first and second levels respectively, the first level being lower than the second level, to control the use of the first and second regenerative braking modes.
- the invention also proposes a control device intended to equip a land vehicle and comprising:
- a powertrain capable of providing first and second selectable regenerative braking modes and making it possible to recover in the vehicle regenerative braking torques having first and second levels respectively, the first level being lower than the second level.
- 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, when the first regenerative braking mode is selected, and when a target acceleration required by the speed control function is less than a potential minimum acceleration that can be ensured by the powertrain in the first regenerative braking mode, in triggering an imposition of the use of the second regenerative braking mode to comply with the speed instruction.
- the invention also provides a land vehicle, possibly of the automobile type, and comprising:
- a powertrain capable of providing first and second selectable regenerative braking modes and making it possible to recover in the vehicle regenerative braking torques having first and second levels respectively, the first level being lower than the second level, and
- this vehicle may include a rechargeable battery capable of storing electrical energy
- the powertrain may include at least one electric motor capable of recovering the regenerative braking torque and transforming this recovered regenerative braking torque into electrical energy to recharge the rechargeable battery.
- FIG. 1 schematically and functionally illustrates an exemplary embodiment of a land vehicle comprising a control device according to the invention, a speed control calculator, and a hybrid GMP transmission chain and supervision calculator,
- 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 of the use of the first m1 and second m2 regenerative braking modes of a land vehicle V with FCV speed control function.
- 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 relates in fact to any type of land vehicle comprising a powertrain (or GMP) comprising at least one electric motor, a speed control function, and first and second selectable regenerative braking modes making it possible to recover regenerative braking torques having first and second levels respectively, the first level being lower than the second level (here we are talking about absolute values).
- GMP powertrain
- FIG. 1 schematically shows a (land) vehicle V comprising a hybrid GMP transmission chain (and therefore in particular with a thermal motor MMT and an electric motor MME), a supervision computer CS, a rechargeable battery BR, an accelerator pedal PA, a speed control computer CA, and a control device DC3 according to the invention.
- a (land) vehicle V comprising a hybrid GMP transmission chain (and therefore in particular with a thermal motor MMT and an electric motor MME), a supervision computer CS, a rechargeable battery BR, an accelerator pedal PA, a speed control computer CA, and a control device DC3 according to the invention.
- the GMP could also be of the all-electric type.
- the transmission chain could also allow a four-wheel drive (or 4x4) or 4x2 mode.
- the transmission chain also comprises, here, a drive shaft AM, a first coupling device DC1, a second coupling device DC2, a gearbox BV, and a transmission shaft AT.
- the operation of the transmission chain (and therefore of the GMP) is supervised by a CS supervision calculator.
- the thermal motor MMT comprises a crankshaft (not shown) which is fixedly secured to the motor shaft AM in order to drive the latter (AM) in rotation.
- This thermal motor MMT is capable of being coupled to the gearbox BV via the first coupling device DC1, as well as here via the second coupling device DC2 (optional).
- it (MMT) is capable of being coupled to the primary shaft AP of the gearbox BV via the first coupling device DC1, as well as here via the second coupling device DC2 (optional).
- This coupling device DC1 is capable of delivering a second torque c2 from the first torque c1 produced by the thermal motor MMT, for the gearbox BV.
- this gearbox BV is capable of delivering a third torque c3 from the second torque c2 delivered by the coupling device DC1, for at least one train T1 of drive wheels.
- This third torque c3 is defined by a torque instruction ccg which is transmitted by the CS supervision calculator.
- 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 first coupling device DC1 can be a clutch (single or double). But it could also be a torque converter or a dog clutch.
- the BV gearbox may be of the so-called “dual clutch (or DCT)” type.
- DCT dual clutch
- the invention is not limited to this type of gearbox. It should be noted that it is however preferable for the BV gearbox to be automated.
- crankshaft of the thermal motor MMT is also coupled to a belt CC, itself coupled to an alternator-starter AD which is supplied with energy electric by the rechargeable battery BR (and which can also recharge the latter (BR)).
- alternator-starter AD can supply torque to the belt CC, which can supply this torque to the crankshaft.
- this rechargeable BR battery can, for example, be of the 48 V type. But this is not an obligation. Indeed, it could alternatively be of the 12 V, 24 V, or 400 V type for example.
- the electric motor MME is (here) installed between the thermal motor MMT and the first coupling device DC1, and is capable of providing torque on the order of the supervision computer CS when it is supplied with electrical energy by the rechargeable battery BR. It (MME) is also capable of recovering a regenerative braking torque, defined by a regenerative braking torque setpoint (negative), to brake the vehicle V, and of transforming this recovered regenerative braking torque into electrical energy to recharge the rechargeable battery BR.
- a regenerative braking torque defined by a regenerative braking torque setpoint (negative)
- the first coupling device DC1 When the first coupling device DC1 has been placed in its fully coupled (or fully closed) state and the thermal motor MMT provides torque (positive) and/or the electric motor MME provides torque (positive), the first coupling device DC1 delivers torque for the primary shaft AP of the gearbox BV.
- the transmission chain comprises a second coupling device DC2 installed between the thermal motor machine MMT and the first coupling device DC1 , in order to allow coupling of the electric motor machine MME between the first DC1 and second DC2 coupling devices.
- the second coupling device DC2 when the second coupling device DC2 has been placed in its fully decoupled (or fully open) state, only the electric motor machine MME can provide torque upstream of the first coupling device DC1 .
- this second coupling device DC2 can be a clutch.
- the first coupling device DC1, the possible second coupling device DC2, the electric motor MME and the gearbox BV are part of a gearbox assembly EBV. But this is not an obligation.
- the accelerator pedal PA can be actuated (here) by a foot of the driver of the vehicle V. It has a percentage of depression from which the torque setpoint ccg is defined, which is then representative of the driver's wishes.
- the speed control calculator CA provides at least one speed control function FCV within the vehicle V during assisted speed control phases during which it controls the current speed vv of the vehicle V according to a speed setpoint cv. It is considered in the following, by way of non-limiting example, that the speed control function FCV is a speed limitation function capable, in the event of activation, of generating a torque setpoint ccg allowing the vehicle V not to exceed a speed setpoint cv. This generated torque setpoint ccg is then transmitted to the supervision calculator CS.
- the torque setpoint ccg is determined by the speed control function FCV as a function of an acceleration that it has determined as a function of the difference between the speed setpoint cv to be respected and the current speed vv of the vehicle V and of minimum and maximum accelerations which are a function of this difference.
- the invention is not limited to this type of speed control function. It relates to any type of speed control function capable of generating a torque setpoint as a function of a speed setpoint.
- the FCV speed control function could also be a speed regulation function or a speed restriction function or even a speed and distance regulation function between vehicles (or ACC (“Adaptive Cruise Control”)), for example.
- the speed control calculator CA and the supervision calculator CS can, for example, communicate via an internal communication network RC of the vehicle V, possibly multiplexed, as illustrated non-limitingly in FIG. 1.
- the vehicle V also offers first m1 and second m2 regenerative braking modes which are selected by its driver and make it possible to recover regenerative braking torques having respectively first n1 and second n2 levels.
- first level n1 (called weak or spinning) is lower than the second level n2 (called strong, or “brake” in English). It is important to note that when a level is mentioned, it is an absolute value.
- the invention proposes in particular a control method intended to allow the control of the use of the first m1 and second m2 regenerative braking modes of the vehicle V, when the first regenerative braking mode m1 has been selected by the driver and the FCV speed control function has been activated (for example by the driver).
- 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 (“Digital Signal Processor”)), 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, or could be part of another computer embedded in the vehicle V and providing at least one other function, such as for example the speed control computer CA.
- the (control) method according to the invention comprises a step 10-50 which is implemented each time the FCV speed control function has been activated.
- Step 10-50 of the method comprises a sub-step 30 in which, when the first regenerative braking mode m1 is selected, and when a first target acceleration ac1 required by the FCV speed control function is less than a potential minimum acceleration amp that can be ensured by the GMP in the first regenerative braking mode m1, the use of the second regenerative braking mode m2 is imposed (for example the control device DC3 triggers the imposition of) to comply with the speed setpoint cv.
- the invention is therefore particularly advantageous, although not limitingly, when the vehicle V is on a downward slope. [0067] Furthermore, the invention makes the speed control functions robust to the slope of the traffic lanes regardless of the driving mode selected by the driver. Furthermore, the invention allows completely transparent operation for the driver.
- step 10-50 of the method may comprise a sub-step 20 in which one (for example the control device DC3) may compare the first target acceleration ac1 required by the FCV speed control function to the potential minimum acceleration amp that can be ensured by the GMP in the first regenerative braking mode m1. If the first target acceleration ac1 is greater than the potential minimum acceleration amp, one (for example the control device DC3) may start to perform step 10-50 of the method again. On the other hand, if the first target acceleration ac1 is less than the potential minimum acceleration amp, one (for example the control device DC3) performs sub-step 30.
- one for example the control device DC3 may compare the first target acceleration ac1 required by the FCV speed control function to the potential minimum acceleration amp that can be ensured by the GMP in the first regenerative braking mode m1. If the first target acceleration ac1 is greater than the potential minimum acceleration amp, one (for example the control device DC3) may start to perform step 10-50 of the method again. On the other hand, if the first target acceleration
- step 10-50 of the method may comprise a sub-step 10 in which one (for example the control device DC3) may begin by determining whether the first regenerative braking mode m1 has been selected, in the presence of the activation of the FCV speed control function. If not, one (for example the control device DC3) may start to perform step 10-50 of the method again. On the other hand, if so (first regenerative braking mode m1 selected), one (for example the control device DC3) performs sub-step 20.
- one for example the control device DC3 may begin by determining whether the first regenerative braking mode m1 has been selected, in the presence of the activation of the FCV speed control function. If not, one (for example the control device DC3) may start to perform step 10-50 of the method again. On the other hand, if so (first regenerative braking mode m1 selected), one (for example the control device DC3) performs sub-step 20.
- step 10-50 of the method may comprise a sub-step 40 in which, once the second regenerative braking mode m2 has been imposed in sub-step 30, one (for example the control device DC3) may determine whether a second (or other) target acceleration ac2, defined as a function of the percentage of depression of the accelerator pedal PA, is less than the potential minimum acceleration amp. If so, one (for example the control device DC3) may maintain the imposition of the second regenerative braking mode m2, and therefore one (for example the control device DC3) can perform substep 30 again.
- a second target acceleration ac2 defined as a function of the percentage of depression of the accelerator pedal PA
- This option is intended to determine whether there is a potential conflict between the driver's will, represented by the second (or other) target acceleration ac2, and the need for recovery of regenerative braking torque of the FCV speed control function. It will be understood that the driver's will takes priority over the recovery of regenerative braking torque. In other words, if the driver wants to brake his vehicle V, for example because he is getting too close to the vehicle in front of his, he will press the accelerator pedal PA less, and therefore the absolute value of the second (other) target acceleration ac2 will be greater than that of the potential minimum acceleration amp, which means that it is necessary to maintain the imposition of the second regenerative braking mode m2.
- the supervision calculator CS (or the calculator of the control device DC3) can also comprise a mass memory MM1, in particular for storing the speed setpoint cv, the first target acceleration ac1, the second target acceleration ac2 and the potential minimum acceleration amp, as well as any intermediate data involved in all its calculations and processing.
- this calculator of supervision CS may also comprise an input interface IE for receiving at least the speed setpoint cv, the first target acceleration ac1, the second target acceleration ac2 and the potential minimum acceleration amp, possibly after having shaped and/or demodulated and/or amplified them, in a manner known per se, by means of a digital signal processor PR2.
- this supervision CS calculator (or the calculator of the control device DC3) may also comprise an output interface IS, in particular for delivering each message containing an order to impose the second regenerative braking mode m2 or each message containing an order to stop imposing the second regenerative braking mode m2.
- 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 use of the first m1 and second m2 regenerative braking modes when the first regenerative braking mode m1 has been selected in the vehicle V.
