- FIG. 1 schematically illustrates an embodiment of a motor vehicle 100 with hybrid motorization, in particular a vehicle with electric hybrid motorization or rechargeable electric hybrid motorization.
- the vehicle 100 comprises a heat engine 101, at least one electric motor 102 and a transmission 103.
- the vehicle 100 comprises an electric motor 102, the present invention can nevertheless extend to a vehicle comprising a plurality of electric motors 102.
- the vehicle 100 is furthermore equipped with a system 10 for counting a distance traveled by the vehicle 100 and/or with a monitoring installation 20 comprising such a counting system 10.
- the vehicle is also equipped with a storage device 104 of electrical energy, or battery, capable of cooperating with the at least one electric motor 102, in particular to supply it with electrical energy.
- the accounting system 10 comprises at least one means 11 for measuring a distance of movement of the vehicle, for example in kilometers, a processing unit 12 and a first odometer 13 and at least one second odometer 14.
- the measuring means 11 is capable of detecting and/or measuring a movement of the vehicle and of transmitting a signal depending on a value of the distance d n ;n+i of movement, in particular towards the processing unit 12. by “movement” the movement of the vehicle forwards or in reverse.
- the measuring means 11 is capable of emitting a signal representative of a distance value of these different displacements.
- the measuring means 11 can comprise an odometer, in particular placed at the level of the chassis of the vehicle.
- the measuring means 11 can comprise at least one sensor capable of detecting and/or measuring the movement of the vehicle as a function of a movement of a wheel with respect to a defined reference frame.
- the processing unit 12 comprises at least one calculation unit, or computer, comprising hardware and software resources, more precisely at least one processor or microprocessor, which cooperates with memory elements.
- the at least one computer is capable of executing instructions for implementing a computer program, in particular in order to execute the steps of a method as detailed below.
- the processing unit 12 is in particular able to receive the signal coming from the measuring means 11 .
- the processing unit 12 is, moreover, capable of detecting and/or controlling, in real time, a torque of the combustion engine 101 and a torque of the electric motor 102 on the transmission 103.
- the at least one computer of the processing unit 12 can be capable of detecting and controlling the torque of the heat engine 101 and of the electric motor 102, that is to say to impose a torque to be applied, according to need or according to a driving mode implemented by the vehicle.
- a first computer of the processing unit 12 can control the torque of the heat engine 101 and of the electric motor 102 and communicate data relating to such control to a second computer.
- the processing unit 12 is capable of selectively transmitting a signal to the first odometer 13 and/or to the second odometer 14, in particular a signal depending on the distance value of the movement made measured by the measuring means 11 .
- the first odometer 13 is configured to be incremented by the measured distance value d n ;n+i of the displacement only when the heat engine 101 is rotating.
- rotating is meant that the internal combustion engine is driven, that is to say that it is not switched off or cut off.
- Such a state of the heat engine 101 can in particular be detected by the computer of the processing unit 12.
- the first odometer 13 indicates a first distance traveled by the vehicle when the heat engine 101 is in operation.
- the first odometer 13 is configured to be incremented by the measured distance value d n ;n+i of the displacement only when the heat engine 101 is coupled to the transmission 103 of the vehicle . In other words, the heat engine 101 is then rotating and coupled to the transmission 103.
- Di ;n is a value of the first distance at a time t n .
- the instant t n can be prior to the movement of the vehicle or prior to an adjustment of the value of the first distance, for example when the value of the first distance is adjusted in real time or at a predetermined regular time interval.
- the value of the first distance obtained at a time t n+i following the movement of the vehicle or subsequent to an adjustment of the value of the first distance is called Di ;n+i .
- Such first distance values Di ;n and Di ;n+i can be stored, for example in the memory element of the processing unit 12.
- the processing unit 12 detects that the heat engine 101 is coupled to the transmission 103, that is to say it has a non-zero torque, and controls the first odometer 13 so that it is incremented, that is to say so that it adds the value of distance d n ;n+ i measurement of the movement made by the vehicle at the value of the first distance Di ;n recorded in order to obtain an updated value of the first distance Di ;n+i .
- electric motor 102 is coupled to the transmission at all times. However, it may be required to present, according to a setpoint imposed on it, a zero torque for which it has no effect on the acceleration or deceleration of the vehicle.
- non-zero torque is meant a positive torque or a negative torque.
- the processing unit 12 detects in particular, via the computer, the torque and the use made of the electric motor 102, for example if it is used to allow acceleration, if it functions as a regenerative brake or if it has a zero torque, that is to say equal to 0 nm, as explained further below.
- a positive torque can be defined as being a torque greater than a predefined threshold according to the maximum torque that the electric motor 102 can deliver, that is to say greater than the sum of 0 Nm and said threshold and a negative torque can be defined as a torque lower than a predefined threshold according to the maximum torque that the electric motor can deliver, that is to say lower than the subtraction of said threshold from 0 Nm.
- a negative torque can be defined as a torque lower than a predefined threshold according to the maximum torque that the electric motor can deliver, that is to say lower than the subtraction of said threshold from 0 Nm.
- the second odometer 14 is therefore particularly configured to be incremented by the distance value d n; n+i measured displacement only when the electric motor 102 of the vehicle has a non-zero torque.
- the second odometer 14 thus indicates a second distance traveled by the vehicle when the electric motor 102 is operating under conditions contributing to its wear in a not insignificant manner.
- D2 ;n denotes a value of the second distance at a time t n, for example prior to the movement of the vehicle or prior to an adjustment of the value of the second distance, as described above.
- the value of the second distance obtained at a time t n+i following the movement of the vehicle or being subsequent to an adjustment of the value of the second distance is called D2 ;n+i .
- these values D2 ;n and D2 ;n+i can be stored on the memory elements.
- the processing unit 12 When the processing unit 12 detects that the electric motor 102 has a non-zero torque, it controls the second odometer 14 so that it is incremented, that is to say so that the distance value d n -n +i measured of the movement made by the vehicle is added to the second distance value D2 ;n recorded so as to obtain an updated value of the second distance D2 ;n+i .
- the system according to the invention can comprise a single second odometer 14 configured to be incremented by the distance value d n ;n+i of the displacement measured only when at least one of the electric motors 102 of the vehicle has a non-zero torque.
- the accounting system may comprise a plurality of second odometers 14, each of said second odometers 14 being configured to be incremented by the distance value d n;n+i measured from the displacement only when an engine electric 102 which is specific to it, that is to say with which it is associated, has a non-zero torque.
- Such a principle extends to the accounting method according to the invention.
- the system according to the invention can advantageously control the incrementation of the first odometer 13 and/or of the second odometer 14 according to the driving mode implemented by the vehicle, as further explained below. Consequently, the invention also makes it possible to take into consideration the type of vehicle with hybrid motorization, in particular simple or rechargeable, said modes being caused to vary according to the type of vehicle.
- the accounting system 10 may further comprise a display unit 16 for the first odometer 13 and/or the second odometer 14.
- a display unit 16 can be integrated into a edge of the vehicle or even to a man-machine interface of the vehicle, already integrated into the vehicle, in order to indicate the first distance traveled and/or the second distance traveled.
- the counting system 10 can also comprise a counting device 17, in other words an odometer, of a total distance Dtot traveled by the vehicle.
- a total distance Dtot can be counted when the vehicle is moving in forward gear only or, alternatively, when the vehicle is moving in forward gear or in reverse gear.
- the counting device 17 is configured to be incremented by the distance value d n ;n+i of movement of the vehicle.
- the accounting device 17 does not take into consideration the torque of the electric motor 102 or of the heat engine 101 on the transmission 103, and, by extension, the driving mode of the vehicle or the type of vehicle.
- Such a device corresponds to an odometer as known from the prior art and conventionally equipped on vehicles, so it will not be further detailed. Note that, such a device only taking into account the forward motion of the vehicle, the value of the total distance Dtot is not equal to the sum of the first distance and the second distance and may even be less than the first distance, that is to say the distance traveled using the heat engine 101, in particular for vehicles with electric hybrid motorization not rechargeable by connection.
- the invention also relates to a method for counting 1 a distance traveled by the motor vehicle with hybrid motorization.
- a method for counting 1 a distance traveled by the motor vehicle with hybrid motorization can in particular be assimilated to a method of operating or using the accounting system 10 as set out above and, similarly, the system can be considered as an accounting system comprising the means necessary for the implementation of the accounting method 1 according to the invention.
- the method comprises, as illustrated in FIG. 2, a step E1 of measuring a distance value d n ;n+i of a displacement of the vehicle by the measuring means 11 and a step of transmitting E2 said value measured at the processing unit 12.
- steps can be executed successively one after the other, repeated, or even be at least partly concurrent, for example when the displacement distance value is estimated in real time or updated cyclically.
- the method then comprises a step E3 of incrementing the first odometer 13 of the displacement value, implemented only when the heat engine 101 of the vehicle is coupled to a transmission 103 of the vehicle, and/or a step of incrementing E4 of a second odometer 14 of the distance value of movement only when the electric motor 102 of the vehicle has a non-zero torque.
- the method may include a step E3 of incrementing the first odometer 13 or a step of incrementing E4 the second odometer 14, or these two steps E3, E4.
- the method may comprise an additional step, not shown, of displaying the first distance and/or the second distance, respectively specific to the first odometer 13 and to the second odometer 14 via the display unit 16.
- a vehicle with simple or rechargeable hybrid motorization can conventionally implement all or part of the operating modes below, in particular a so-called “electric propulsion” driving mode with or without “regenerative braking” mode, as well as all or part of the different "thermal propulsion” driving modes such as:
- the hybrid vehicle When the hybrid vehicle operates in “electric propulsion” mode, in the acceleration phase or in the rolling phase of the vehicle, only the electric motor 102 is involved in the propulsion force of the vehicle.
- the heat engine 101 is decoupled from the transmission 103 and the electric motor 102 has a positive torque, that is to say strictly greater than 0 Nm.
- the first odometer 13 is not incremented while the second odometer 14 is incremented by the displacement distance value measured by the measuring means 11 .
- a "regenerative braking” mode can be activated in order to ensure the recovery of energy, and therefore the recharging of the storage 104, during braking of the vehicle.
- the heat engine 101 is decoupled from the transmission 103 and may or may not be rotating while the electric motor 102 has a negative torque, strictly less than 0 Nm.
- the first counter kilometer 13 is then not incremented while the second odometer 14 is incremented by the value of the displacement distance.
- the electric motor 102 can be controlled in order to present zero torque, that is to say equal or substantially equal to 0 Nm.
- the incrementation of the second odometer 14 is interrupted as soon as storage device 104 is charged to its maximum capacity, thereby preventing the need for dissipation of excess energy by Joule effect.
- the second odometer 14 is therefore based on the zero torque information which itself takes into account the case of a storage device 104 which is already fully charged.
- the system according to the invention is then not directly a function of the storage device 104 but a function of the torque of the electric motor 102 and the incrementation of the second odometer 13 is automatically interrupted. Neither the first odometer 13 nor the second odometer 14 are then incremented.
- a similar principle applies, during the braking phases, when the vehicle uses “electric propulsion” driving and the “regenerative braking” mode is deactivated.
- a vehicle with a hybrid electric motor that is not rechargeable by connection will have a reduced range than a plug-in hybrid motor vehicle for the implementation of such a mode.
- some vehicles with a hybrid electric motor that cannot be recharged by plugging in may be devoid of the "electric propulsion" mode in the sense that the electric motor 102 cannot operate alone and that it necessarily requires the simultaneous operation of the heat engine 101, in other words the coupling of the heat engine 101 to the transmission 103, to exert a propulsive force.
- the propulsion force is produced by the internal combustion engine 101 and the latter is assisted by the electric motor 102.
- the engine 101 is then coupled to the transmission 103 and the electric motor 102 has a positive torque, the processing unit 12 receiving in particular the information relating to the torque of the electric motor 102 via the computer.
- the first odometer 13 is incremented by the distance value d n ;n+i of displacement measured during the acceleration by the measuring means 11 and the second odometer 14 is incremented by this same distance value.
- the propulsion effort is entirely carried out by the heat engine 101.
- the heat engine 101 is coupled to the transmission 103 and the electric motor 102 has zero torque.
- the first odometer 13 is incremented by the distance value d n ;n+i of displacement measured by the measuring means 11 but not the second odometer 14.
- the “recharging during driving phase” mode can be activated in order to allow the recharging of the storage device 104 of electrical energy via the electric motor 102.
- the thermal engine 101 is coupled to the transmission 103 in order to ensure the propulsion force of the vehicle while the electric motor 102 has a negative torque.
- the first odometer 13 is incremented by the distance value d n ;n+i of displacement measured by the measuring means 11 and the second device is incremented by this same value.
- the electric motor 102 can be controlled so as to present a zero torque, that is to say equal or substantially equal to 0 Nm. The incrementation of the second counter is then automatically interrupted.
- the thermal engine 101 is coupled to the transmission 103 in order to ensure the propulsion force of the vehicle while the electric motor 102 presents a torque negative allowing the recharging of the storage device 104 of electrical energy.
- the first odometer 13 and the second counter are incremented by the distance value d n ;n+i of displacement measured during the braking phase.
- the electric motor 102 is controlled so as to present zero torque. It follows that the incrementation of the second odometer
- the heat engine 101 When the "regenerative braking" mode is deactivated, as for the deactivation of the "acceleration assistance” mode or of the “recharge during driving phase” mode, the heat engine 101 is coupled to the transmission 103 and the motor electric 102 has zero torque.
- the accounting system 10 increments the first odometer 13 but not the second.
- the accounting system 10 thus allows a more precise accounting of the mileage achieved by the vehicle by taking into account the actual use of the heat engine 101 and of the electric motor 102, and therefore, indirectly, the mode of operation of the vehicle from those set out above.
- such a device when the system is equipped with a device 17 for counting the total distance Dtot traveled by the vehicle, such a device can, in addition to the first and/or the second odometer 13, 14 , be incremented by the distance value d n ; n+i of movement when the vehicle is moved in forward gear.
- the hybrid motor vehicle simple or rechargeable
- a so-called “freewheeling” mode also called “sailing” or “coasting” in English
- the heat engine 101 is decoupled from the transmission 103 and the electric motor 102 has, simultaneously, zero torque.
- Such an operating mode can in particular be implemented when the vehicle is moving down a slope or when approaching a traffic light.
- the accounting system 10 can, moreover, optionally comprise a third odometer 18 configured to increment a third distance D 3 traveled by the vehicle by the distance value d n; n+i of the displacement only when the heat engine 101 of the vehicle is decoupled from the transmission 103 and the electric motor 102 of the vehicle has, simultaneously, zero torque. It is understood that such a principle is then implemented while the vehicle is moving forward, so that the measuring means 11 determines a non-zero distance of movement of the vehicle. Such a principle can in particular enable the manufacturer to better understand the use that each driver makes of his vehicle.
- the accounting method 1 as explained above can, in addition, comprise a step of incrementing E5 of the third odometer 18 only when the combustion engine 101 of the vehicle is decoupled from the transmission 103 of the vehicle and the engine electrical 102 of the vehicle concomitantly presents zero torque.
- the vehicle implements the “freewheel” mode, only the third odometer 18 and the counting device 17 are incremented but neither the first odometer 13 nor the second odometer 14 are incremented.
- FIG. 3 illustrates a vehicle 100 according to an alternative embodiment substantially similar to the embodiment as described above, so the preceding description, made with reference to FIG. 1 applies mutatis mutandis.
- FIG. 4 illustrates a production method specific to said alternative embodiment for which the description made above with reference to FIG. 2 applies mutatis mutandis.
- the accounting system 10 further comprises a first alternating odometer 13' and/or a second alternating odometer 14'.
- the first alternating odometer 13' is configured to be incremented by the distance value d n; n+i of the displacement weighted by a utilization factor defined as a function of a maximum torque or a maximum power that the heat engine 101 can deliver only when the first odometer 13 is incremented.
- the first alternating odometer 13' operates as a duplicate of the first odometer 13 and also incorporates a weighting representative of the use of the heat engine 101, in particular representative of the mode used.
- the second alternating odometer 14' is configured to be incremented by the distance value d n; n+i of the displacement weighted by a utilization factor defined as a function of a maximum torque or a maximum power that the at least one electric motor 101 can deliver only when the second odometer 14 is incremented.
- the second alternating odometer 14' operates as a duplicate of the second odometer 14 and also incorporates a weighting representative of the use of the electric motor 102, in particular representative of the mode used.
- the utilization factor applied by the first alternating odometer 13' and/or by the second alternating odometer 14' can be defined by calculating an average of the torque requested and/or detected for the engine considered, that is to say the heat engine 101 or the electric motor 102, over 1 km. For example, in a non-limiting manner, for an electric motor having a maximum power of 120 kW, if the vehicle 100 travels 1 km with a torque of 60 kW, then the second odometer 14 is incremented by a displacement distance value of 1 while the second alternating odometer 14' is incremented by 0.5, corresponding to the displacement distance value weighted according to the use of the electric motor 102.
- Such an arrangement makes it possible in particular to define an average utilization factor for each engine of the vehicle according to their maximum torque and/or their maximum power over their lifetime and thus to refine the maintenance needs.
- the method further comprises a step E6 of duplicating the step E3 of incrementing the first odometer 13, implemented as soon as said step of incrementing E3 is executed.
- the first alternating odometer 13' is incremented by the distance value d n; n+i of the displacement weighted by the utilization factor defined as a function of the maximum torque and/or the maximum power that the heat engine 101 can deliver.
- Such a step can, in particular, be executed concomitantly with the step of incrementing E3.
- the method further comprises a step E7 of duplicating the step E4 of incrementing the second odometer 14, implemented as soon as said step of incrementing E4 is executed.
- the second alternating odometer 14' is incremented by the distance value d n; n+i of the displacement weighted by the utilization factor defined as a function of the maximum torque or the maximum power that the at least one electric motor 102 can deliver.
- the invention also relates to a monitoring installation 20 of a hybrid motor vehicle 100 .
- the installation may include the accounting system 10 as described above as well as a data storage unit 21 and an alert module 22.
- the storage unit 21 is capable of storing at least one predetermined threshold distance D s .
- the storage unit 21 and the memory elements of the system can be distinct or included in the same assembly.
- the at least one threshold distance D s can be stored on a database and the vehicle can comprise at least one communication module, not shown, capable of extracting data from said database via a wireless connection, for example 3G, 4G, "Wi-Fi” or "Bluetooth” (registered trademarks).
- the alert module 22 is configured to emit a visual and/or audible and/or haptic alert message when the first odometer 13 and/or the second odometer 14 exceeds at least a predetermined threshold distance D s recorded in the storage unit 21 and/or taken from a database.
- the alert module 22 is configured to be actuated when the first distance traveled and/or the second distance traveled is strictly greater than at least a predetermined threshold distance D s .
- the alert message can, for example, indicate the need to check the wear of a component of the vehicle and/or to replace a component of the vehicle and/or to carry out an overhaul of the vehicle.
- the at least one threshold distance D s can be specific to at least one component of the vehicle so that the alert message includes at least one indication of the component concerned.
- such a message may include the activation of one or more indicator lights associated with the organ in question, already integrated in the vehicle's dashboard.
- the invention also relates to a method 2 for monitoring the motor vehicle with hybrid motorization, said method can be likened to a method for operating or using the monitoring installation 20 and, conversely, said installation comprises the means necessary for implementation of the monitoring method 2.
- Such a method comprises an execution phase of the accounting method 1 as set out above as well as a step E21 of detecting an overrun of at least a predetermined threshold distance D s by the first odometer 13 and/or by the second odometer 14 and a step E22 of sending a visual and/or sound and/or haptic warning message of such an overrun.
- the installation and the method according to the invention can, in addition, be configured to allow the detection of an overrun E21′ of at least one threshold distance D s ′, preferably distinct from the value of the threshold distance D s , predetermined by the counting device 17 of the total distance D t o t covered in forward gear and a step E22' of sending a visual and/or sound and/or haptic warning message of such an overrun .
- Such an installation and such a method allow more suitable and more precise monitoring of the wear of the components of the vehicle according to the actual use made of them, that is to say according to the driving modes implemented. work.
- the total distance D t o t of the counting device 17 can be taken into account.
- the second distance, specific to the second odometer 14 can be taken into account, and for components relating to the thermal motorization, such as injectors or timing belts, the first distance, specific to the first odometer 13, can be taken into account.
- the present invention thus proposes a method and an accounting system making it possible to evaluate with greater precision and in a more representative manner the wear and tear of a vehicle according to its actual use.
- the use of such vehicles varies considerably according to the type of vehicle, its model and according to the users.
- the invention notably implements the incrementation of a first odometer by a displacement value only when a heat engine of the vehicle is coupled to a transmission of the vehicle, and/or the incrementation of a second odometer of said travel distance value only when an electric motor of the vehicle has a non-zero torque.
