Definitions
- the present invention relates to vehicles of the type called "parallel hybrid".
- Parallel hybrid vehicles are capable of driving by indifferently using the thermal energy supplied by the internal combustion engine and / or the electrical energy supplied by an electric traction machine. To do this, they are, for example, equipped with a heat engine / gearbox assembly on the front axle of the vehicle and an electric machine placed on the rear axle of the vehicle.
- the vehicle includes the following main organs:
- MTH internal combustion engine 11 of the gasoline, diesel or other type
- a coupling / decoupling system 12 constituted by a clutch (hereinafter referred to as "EMB"), of dry, wet or other type;
- MEL electric propulsion machine 13
- BV gear reduction system 14
- N discrete ratios consisting of a torque-controlled mechanical gearbox (“BVMP”), coupled to the front axle of the vehicle V (17D and 17G wheels) ), or a transmission known as “dual clutch transmission”("DCT”), an automatic gearbox (“BVA”) or any other organ performing a similar function;
- BVMP torque-controlled mechanical gearbox
- DCT dual clutch transmission
- BVA automatic gearbox
- BAT power battery 15
- electrical energy storage system for traction a power battery 15 (hereinafter referred to as "BAT") or an electrical energy storage system for traction
- a starting system 16 independent of the heat engine 11 comprising a controlled starter, a system called “Stop & Start” or any other system performing a similar function.
- the battery 15 supplies electrical power to the "MEL” 13 (for traction in electric mode), the “SDI” 16 (during the starting phases of the engine), as well as conventional vehicle components (not shown: headlights, etc.).
- each vehicle member is driven by a close control computer (not shown in FIG. 1) of its own.
- These computers are themselves controlled by a single computer 10 commonly called “control supervisor” who makes the decisions and synchronizes the actions to meet the will of the driver (not shown in Figure 1).
- This computer 10 controls the complete chain of traction, according to various life situations and the state of the vehicle V.
- the computer 10 decides the running mode of the vehicle V, coordinates all the transient phases and chooses the appropriate operating points to optimize the fuel consumption, the depollution and the approval of the vehicle V.
- the computer 10 communicates with the plurality of computers associated with the various members of the vehicle V via electrical links, under the reference 150. Conveniently, it is more generally a data bus. This technology is well known to the skilled person and it is useless to describe it further.
- the “MEL” 13 fixed on the rear axle (wheels 18D and 18G), provides the necessary torque to advance the vehicle V when the engine 11 is stopped.
- the "MEL” 13 of the rear axle in turn applies a “wheel torque” in order to complete partially or completely this torque break.
- This operating strategy is commonly called “Torque Offset Compensation”.
- Patent FR 2 796 437 B1 (RENAULT) teaches a controlled gear change device using an auxiliary electric machine to eliminate, at least mitigate, torque breaks during a shift to a higher gear.
- the organic architecture of the vehicle is entirely different from that of the invention, which leads to a problematic also distinct.
- the electric machine is arranged on the crankshaft of the engine and not on the rear axle. It is not, strictly speaking, to compensate for a break in torque during a gearshift and no longer solve problems of approval in passing games that are not considered.
- Patent FR 2 784 058 B1 (LUK GETRIEBE SYSTEME GMBH) teaches a gearbox comprising an integrated electrical machine making it possible to compensate the torque break by an increasing contribution of the torque of this electric machine during the switching process.
- the parameter "driving pleasure" and / or the problems related to the passage of games were considered.
- the invention proposes a method and a device which, while retaining the advantages of those of the prior art, and in particular those of the aforementioned patent application FR 2 907 409 A1, makes it possible to obtain a gear change.
- gearbox with complete compensation for breaking torque that is to say by integrating predetermined driving comfort constraints, especially during the game changes of the rear axle.
- the invention allows a complete respect of the will of the driver during the gearshift phases with torque failure compensation.
- the invention makes it possible to optimize a scrupulous setpoint tracking during these gearshift phases with wheel torque breaking compensation.
- the main object of the invention is therefore a method of compensating for failure of the engine torque supplied by the powertrain of a vehicle of the so-called "parallel hybrid” type, said vehicle comprising at least one set of front wheels, a heat engine coupled to a gearbox for transmitting to the front axle a driving torque for different transmission reduction ratio of the gearbox, called “front-end torque", the gearbox causing a break in the engine torque during a switching process of the transmission gear ratio, a rear wheel rear axle, and an electric machine, coupled to the rear axle, for transmitting to the rear axle an additional engine torque of the front axle torque and / or compensation of said torque break, referred to as "rear-wheel torque", the rear suspension associated with at least one physical variable known as "rear-wheel-drive stress” , characterized in that it comprises at least the following steps: a / acquisition of a "global train” torque setpoint value imposed by the driver of the vehicle, the overall torque being equal at all times to the sum of the front and rear train couples; b /
- FIG. 1 schematically illustrates a hybrid vehicle architecture according to the known art
- FIGS. 2A is a set of curves illustrating the different efforts
- FIG. 3A is a set of curves illustrating the various forces experienced by a hybrid vehicle, of the type of FIG. 1, putting a method of compensating for breaks in torque according to a preferred embodiment of the invention
- FIG. 3B is a set of curves illustrating the corresponding ratio variations.
- FIGS. 2A and 2B are the axes of times t (s), graduated in seconds arbitrarily, but with identical and correlated scales.
- the ordinate axis of Figure 2A is arbitrarily graduated into torque values (in N. m).
- the ordinate axis of Figure 2B illustrates two ratios of the robotized gear box (Figure 1: 14), arbitrarily called R1 and R2.
- Curve 30 represents a request to change the ratio of the box robotic ( Figure 1: 14), or setpoint, and the curve 31 represents, at each moment, the ratio actually engaged.
- phase p4 time t3 to t4: end of change of ratio
- time t3 a variation of the vehicle wheel torque made with respect to the setpoint CC (curve 20).
- the torque profile of the rear axle is constrained by the passage around the games (zone symbolized by an ellipse JAR2) while the front axle is not constrained.
- the variation of the curve 22 can not present a gradient as large as the theoretical curve 22 "(in dotted lines).
- the actual curve 22 has a first point of inflection at time t'3 ⁇ t4, and a second point at time t4, to reach a final value CAR2 at instant t'4> t4. It follows that the global wheel torque (curve 23) increases with a small slope (above the setpoint: DC torque), until the instant t'3 ⁇ t4, then with a larger slope until the moment t4.
- FIGS. 3A and 3B showing sets of curves, respectively 4 and 5, corresponding to those, 2 and 3, of FIGS. 2A and 2B.
- the vehicle architecture is similar to that shown in the figure.
- the following is a description of the specificities of a vehicle architecture allowing the implementation of the method according to the invention with reference to the description of FIG. 4. It will be shown moreover that the architecture of the vehicle does not require any substantial modification, which is an additional advantage presented by the method of the invention.
- the powertrain of the vehicle ⁇ / is in hybrid mode and the will of the driver, represented by the DC torque setpoint, remains stable (dashed curve) 40).
- the front axle is at its optimum operating point (FIG.
- phase p3 times t2 to t3: commitment
- it is the rear axle that realizes all (curve 43) of the vehicle wheel torque CC (curve 40) desired by the driver.
- phase p4 time t3 to t4: end of gear change
- time t3 good tracking the vehicle wheel torque (curve 43) made with respect to the setpoint CC (curve 40).
- hybrid hybrid type vehicle architecture 1 allows the implementation of the method according to the invention with reference to FIG. 4.
- this architecture 1 ' can be, essentially, if not identical, but quite similar to that of the known art described with reference to FIG.
- the first parameter is the global torque setpoint of wheels, which has been called CC, resulting from the will of the driver (symbolized by a figurine referenced “driver” in Figure 4).
- this first parameter is common to the methods of the prior art, even though it does not appear explicitly on the simplified architecture of FIG. 1. However, and precisely as it has been found, it can not be respected. at least during the shift phases (Figure 2A: p2 to p4).
- the DC setpoint is acquired by any appropriate means: for example a control keyboard on the dashboard (not shown) of the vehicle associated with a display member, etc. In itself, such means are known to those skilled in the art.
- This setpoint value CC is then transmitted to the computer 10, for example via an electrical connection Icc, in analog or digital form. It must therefore comprise interface circuits accepting the signals representative of the DC setpoint value and converting them, if necessary, into digital signals, the current computers being generally of the digital type with recorded program.
- the CC value is stored in memory means provided with the computer, volatile (for example of the type "RAM” for "Random Access Memory” in the English terminology ") or (re) programmable (for example of the type" PROM ").
- torque setpoint CC can be stored locally in the input means, for example a close computer communicating with the computer 10 'via the data transmission links (or a bus) 100'.
- the second parameter which is more specific to the invention, consists of data representative of the rear axle clearance constraints. These data can be acquired by experimentation or calculation. They depend on the actual physical characteristics of the constituent parts of the vehicle, and in the first place on the components directly related to the engine (heat engine, electric machine), to the gear change (type of gearbox) and to the rolling gear (trains, wheels, etc.).
- the data representative of the aforementioned rear axle clearance constraints are stored in memory means, for example a zone M, referenced 101 'of the memory associated with the computer 10'. Although shown separately, it should be understood that this zone may simply consist of ordinary memory addresses memory of the computer 10 '.
- the rear axle clearance data may also be acquired, at least in part, by onboard measurement means (various sensors), which allows the recorded data to be refreshed as needed throughout the life of the vehicle and according to the operating conditions (speed, configuration of the road, etc.).
- onboard measurement means various sensors, which allows the recorded data to be refreshed as needed throughout the life of the vehicle and according to the operating conditions (speed, configuration of the road, etc.).
- the computer 10 prepares instructions that it transmits to the plurality of so-called close computers and / or decentralized control members, as a function of the control signals that it receives, in particular gearshift commands and subsequent commands and / or state detections (disengagement, gear engaged, etc.), so that the gearshift sequence (phases p1 to p5) is performed correctly.
- the close computers control as previously indicated, thunderstorms that are under their direct control (eg the decoupling of the robotic gearbox, Figure 1: 14).
- the computer 10 'takes into account, to develop the control signals that it transmits to the close computers and / or local control devices the DC torque setpoint and, most importantly, the backlash clearance data.
- this specific operation of the invention can be obtained simply by slightly modifying the program recorded in the computer, that is to say generally a sequence of macro-instructions recorded in a read-only memory (for example type "ROM” for "Read OnYy Memory” or the type “PROM” above, which allows a modification of the recorded program if updates are necessary).
- a read-only memory for example type "ROM” for "Read OnYy Memory” or the type “PROM” above, which allows a modification of the recorded program if updates are necessary.
- the invention has many advantages that have been previously enumerated and needless to be recalled in full.
- the method according to the invention makes it possible, in particular, to comply with the overall wheel torque set point imposed by the driver of the vehicle, including during the gearshift phases, while obtaining an entire torque break compensation.
- the method according to the invention makes it possible to make the gear change completely imperceptible for the driver.
- the method according to the invention does not require any significant modification, which allows the use of well known technologies per se.
- the modifications necessary to implement the method according to the invention and achieve the objectives it has set can be summarized, essentially, in the realization of a minor modification of the program recorded in a calculator already present on this type of vehicle, the gripping devices, acquisition and periodic modification of the overall wheel torque setpoint given by the driver is, a priori, already present on a vehicle of the type referred to by the invention.
- the invention is however not limited to the embodiments described with reference to FIGS. 3A, 3B and 4.
