- TITLE HYBRID GMP VEHICLE WITH DECOUPLINGS OF THE THERMAL DRIVE MACHINE FUNCTION OF THE BAN ON
- the invention relates to land vehicles comprising a hybrid powertrain (or GMP) comprising in particular a thermal drive machine, and more specifically the control of the decoupling of this thermal drive machine from the associated gear change device.
- GMP hybrid powertrain
- Some land vehicles include a power train (or GMP) which has a first thermal drive machine and provide torque for a drive wheel set via a first coupling device and a gear change device, and a second non-thermal drive machine. and providing torque for that same train or for another set of driving wheels via a second coupling device.
- GMP power train
- the term “driving machine” is understood here to mean a thermal or non-thermal machine producing torque for the movements of its vehicle from the energy stored in an energy storage means.
- a thermal power machine is an engine that consumes fuel or chemicals, such as a reactor, a turbojet or a chemical engine, for example.
- a non-thermal drive machine can, for example, be an electric machine (or motor), a hydraulic machine, a pneumatic (or compressed air) machine, or a flywheel.
- the first control device coupling and the gear change device can be controlled electronically (or in an automated manner) a first control of the couplings / decouplings of the first thermal engine machine to / from the gear change device is implemented, and a second control of the gear changes. report.
- the first check is intended to determine the conditions for coupling (or decoupling) the first thermal drive machine in order to use it (or not) to move the vehicle.
- the decoupling of the first thermal drive machine can have the effect of reducing the torque potential at the wheels, of increasing the response time in the event of strong demand on the GMP by the driver (because it is then necessary to re-couple ), and reduce, or even eliminate, the noise generated by the first thermal engine machine.
- the second check is intended to prohibit the change of the gear which is engaged in the gear change device when at least one condition relating to the driving of the vehicle or to the road on which the latter is traveling is detected.
- a shift ban is sometimes referred to as “dynamic correction”.
- the prohibition of changing the gear engaged by a higher gear may be intended, among other things, to keep available to the driver a certain potential of torque at the wheels, and therefore a certain reserve of acceleration / deceleration.
- the upward gear changes have precisely the same effects as those caused by the decoupling of the first thermal engine machine.
- a main drawback of the situation described above is that the first and second checks are carried out in parallel independently of each other. Therefore, in the event of prohibition of a change of the gear engaged by a higher gear, nothing prevents that in parallel one proceeds to the decoupling of the first thermal engine machine, which has the effect of reducing the potential of torque to the wheels since only the second non-thermal driving machine can be used for travel, to increase the response time of the GMP when the driver again requests it strongly, and to cause an acoustic transition that is difficult to understand by the driver due to the passage of a point of operation with a first thermal power machine at high speed directly to a first thermal power machine cut off.
- the aim of the invention is therefore in particular to improve the situation. Presentation of the invention

- its powertrain can comprise another non-thermal drive machine and supplying torque, and another coupling device having closed and open states in which it respectively couples and decouples this other drive machine to a set of drive wheels;
- the other prime mover can be electric and supplied with electric energy by at least one rechargeable battery

- the invention also proposes a computer program product comprising a set of instructions which, when it is executed by processing means, is suitable for implementing a control method of the type presented above for controlling gear change requests in a land vehicle comprising a powertrain including a thermal drive machine and providing torque for a drive wheel train via a coupling device and a gear changing device electronically controllable.

- This first driving machine MM1 is intended to supply torque, on the order of the supervision computer CS, for a first train T1 of driving wheels, via the first coupling device DC1 and the gear change device DCR.
- the first train T1 is located at the front of the vehicle V, and preferably, and as illustrated, coupled to the first transmission shaft AT 1 via a first differential (here before) D1.

- the first coupling device DC1 can be controlled electronically (or in an automated manner), for example by the supervision computer CS.
- this first coupling device DC1 can be a clutch. But it could also be a dog.
- This first coupling device DC1 can take at least two coupling states: a closed state in which it ensures the coupling of the first driving machine MM1 to a primary (or input) shaft AP of the gear change device DCR, and an open state in which it decouples the first drive machine MM1 from this primary shaft AP. It will be noted that when it comes to a clutch, it can also, optionally, take at least an intermediate state in which it provides partial (or sliding) coupling of the first driving machine MM1 to the primary shaft AP.
- the DCR gear change device can be controlled electronically (or automatically), for example by the supervision computer CS. For example, this DCR gear change device can be arranged in the form of a gearbox.

- AT1 to which it is coupled and which is indirectly coupled to the driving wheels (here before) of the vehicle V via the first differential D1.
- the second driving machine MM2 (non-thermal) is responsible for producing torque on the order of the supervision computer CS, from the energy which is stored in an energy storage means BR, for a train of driving wheels ( here the second train T2), when it is coupled to the latter (T2) via the second coupling device DC2.
- the second drive machine MM2 is of the electric type. But it doesn't have to be.
- the second driving machine MM2 supplies torque to the second train T2 which is located at the rear of the vehicle V. But it could supply torque to the first train T1 like the first driving machine MM1 , or else the first driving machine MM1 could supply torque to the second train T2 (rear) and the second machine drive unit MM2 could supply torque to the first train T1 (front).
- the second coupling device DC2 can, for example, be a dog clutch. But it could also be a clutch. In these two cases, the second coupling device DC2 can take at least two coupling states: a closed state in which it ensures the coupling of the second driving machine MM2 to the second transmission shaft AT2, and an open state in which it decouples the second driving machine MM2 of the second transmission shaft AT2. It will be noted that it can also, optionally, take at least one intermediate state in which it ensures partial (or sliding) coupling of the second driving machine MM2 to the second transmission shaft AT2.
- the second coupling device DC2 could be a hydraulic torque converter. But in this case it can take neither a closed state, nor an open state, because it is by nature permanently slippery.
- the energy storage means BR is here arranged to store electrical energy. It is therefore, here, at least one rechargeable battery, for example of the low voltage type (typically 220 V or 400 V or even 600 V).

- the first determination is made as a function of the demand for torque to the wheels required by the driver, and the second determination is made as a function of conditions relating to the driving of the vehicle V and to the roadway on which the latter is traveling (V).
- the vehicle V also comprises a computer designed to perform the operations consisting in prohibiting a request to place the first coupling device DC1 in its open state when the first coupling device DC1 is in its closed state (and therefore when the first driving machine MM1 supplies torque to the first train T1) and as long as a prohibition against changing the gear engaged in the DCR gear changing device is in progress.
- this computer comprises at least one processor PR, for example a digital signal processor (or DSP (“Digital Signal Processor”)), and at least one memory MD performing the aforementioned operations.
- the processor PR can comprise integrated circuits (or printed), or else several integrated circuits (or printed) connected by wired or non-wired 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 MD memory is live in order to store instructions for the implementation by the processor PR of at least part of the control method described below.
- the processor PR and the memory MD advantageously form part of the supervision computer CS. It is in fact the latter (CS) which generates, here, the requests for placing the first coupling device DC1 in its open state and the gear change prohibitions. But in an alternative embodiment, the processor PR and the memory MD could form part of a computer different from the supervision computer CS but coupled (directly or indirectly) to the latter (CS).

- the computer here CS therefore ensures its control selectively and not systematically, regardless of the direction of the gear change (up or down). Its control is in fact ensured only on condition that the prohibition of changing gear results from a condition that is part of the predefined list.
- this predefined list may include a rapid ascent of the accelerator pedal, rolling down a steep descent with the foot not pressing on the accelerator pedal, rolling in a turn inducing lateral acceleration of the accelerator pedal.
- vehicle V above a threshold intervention by a vehicle trajectory control system V, detection of an excessive slip of the driving wheels of the vehicle V, and a ban on changing the gear engaged for a higher gear has been decided by a device for regulating and / or limiting and / or restricting the speed of the vehicle V.

- FIG. An example of an algorithm is schematically illustrated in FIG. implementing a control method according to the invention.
- the algorithm comprises a sub-step 10 in which the placement of the first coupling device DC1 in its closed state is imposed to couple the first prime mover MM1 to the DCR gear change device in order to provide torque to the first train T 1.
- a prohibition on changing the ratio which is engaged in the DCR gear change device is imposed.
- a request is received for placing the first coupling device DC1 in its open state in order to decouple the first driving machine MM1 from the gear change device DCR so that it stops supplying torque to the first. train T 1.

- the placement request is prohibited in a sub-step 50 as long as the prohibition of gear change is in progress (here for the upward direction), and possibly if at least one condition belonging to the list is satisfied, because the first coupling device DC1 is in its closed state.
- the prohibition concerns the downward direction, the placing of the first coupling device DC1 in its open state is authorized, in a sub-step 60.
- the invention also proposes a computer program product (or computer program) comprising a set of instructions which, when it is executed by processing means of the electronic circuit (or hardware) type, such as for example the processor PR is suitable for implementing the control method described above to control gear change requests in the land vehicle V.
