- FIG. 1 is a schematic view of a particular embodiment of a powertrain intended to be used in the context of the present invention
- FIG. 2 is a schematic view of a method according to one embodiment of the invention.
- FIG. 3 illustrates an estimator configured to give a temperature estimate at a given point of an engine
- FIG. 4 illustrates an estimator configured to give a temperature estimate at several given points of an engine
- FIG. 5 illustrates a calculation block of the estimator of FIG. 4.
- the method described hereinafter differs from the prior art notably in that it will make it possible to initialize an estimator by taking into account at least one thermal parameter of the engine, in particular a temperature, the closer to reality.
- the powertrain of a motor vehicle as illustrated in Figure 1 is provided with a motor 1 and an estimator 2 of a temperature at a given point P of the engine 1.
- FIG. 2 illustrates a method of managing such a powertrain, said method comprising an initialization step E1 of the estimator 2 carried out at the start of the powertrain.
- the initialization step E1 comprises a step of determining E1 -1 of a stopping time of a powertrain element.
- starting the powertrain is meant that a driver of the vehicle whose engine is stopped puts the ignition in order to start the vehicle following a stopping phase of the vehicle, for example at a parking space .
- the target element whose stop time is to be determined may be the engine 1, a power train supervision computer 3, etc.
- the element of the powertrain is the supervision computer 3.
- the computer 3 when the driver cuts the engine, the computer 3 remains active for a few seconds (for example a few tens of seconds), this stop activity time is also named "power latch" in the field.
- the computer continues to use the estimator 2 to calculate the actual temperature at the given motor point. At the end of the stop activity time, the estimator 2 goes out.
- this temperature initialization is that of the engine, for example at the given point P, just before the start of said engine.
- the method further comprises a determination step E1 -2 of at least one value representative of the ambient air temperature.
- This step E1 -2 belonging to the initialization step E1 may comprise a temperature measurement step representative of the ambient air temperature by an intake air temperature sensor 4 of the engine 1 and / or a temperature measurement step representative of the ambient air temperature by a temperature sensor 5 at the outside of the vehicle.
- the intake air temperature sensor 4 is generally located in the intake manifold 6 of the engine 1.
- the temperature sensor 5 at the outside of the vehicle can be located on a rearview mirror of the vehicle.
- These two sensors 5 and 6 can be connected to the computer 3 which takes care of acquiring their signals. These measurements are representative of the actual temperature at the time of the end of the downtime, in other words at the time of restart.
- the initialization step E1 of the method comprises a step E1 -3 evaluation of a thermal parameter of the engine 1 as a function of the determined stopping time and the value representative of the ambient air temperature. determined.
- the initialization step E1 of the method comprises an initialization step E1 -4 of the estimator 2 from the evaluated thermal parameter.
- the evaluated thermal parameter is an evaluated temperature of the given point of the motor 1, in particular at the time of the end of the stopping time. This evaluated thermal parameter will thus be able to serve as the initialisation temperature of the estimator 2.
- the evaluation step E1 -3 makes it possible to determine the value at which the thermal parameter should be at the end of the time of stopping the powertrain element.
- This evaluation step E1 -3 can be implemented by the estimator 2, more particularly by calculating means of the estimator 2, before its initialization at the initialization step E1 -4.
- the evaluation step E1 -3 of the thermal parameter comprises a step of determining at least one engine temperature 1 at the start of the stopping time of the powertrain element (this determination step can then be implemented by a step of recovering the at least one engine temperature 1 at the time of the start of the stopping time of the powertrain element stored in a memory), and / or a step of determining at least one value representative of the ambient air temperature at the time of the start of the powerplant element shutdown time (this determination step can then be implemented by a recovery step the at least one value representative of the ambient air temperature at the time of the start of the stopping time of the powertrain element stored in a memory).
- Temperature determined from the engine 1 at the time of the start of the stopping time may be the last engine temperature (for example of the given point) estimated by the estimator 2 before the shutdown of the powertrain element.
- the determined temperature of the ambient air at the time of the start of the downtime of the powertrain element may be the last measured ambient air temperature (for example by the sensors) before the shutdown of the element powertrain.
- the evaluation step E1 -3 of the thermal parameter of the engine 1 can include a step of simulating the evolution of the temperature of the engine 1 (especially at the given point) over time stopping, said simulation step taking into account a heat flux supplied to the engine 1 by its operation of zero value, and determining a thermal flow dissipated from the engine 1 by its cooling.
- the estimator 2 can realize, after the stopping time, a simulation of the evolution of the temperature of the given point P of the engine 1 throughout the stopping time of the element of the group Transmissions.
- the equations for performing this simulation can be the same as those used in real time during the operation of the engine 1, since the estimator itself can calculate the value of the thermal parameter with which it will be initialized.
- the temporal step of the simulation can be of the order of the second. In other words, the estimator 2 will simulate in a very short time the theoretical value of the thermal parameter for each second of the stopping time so as to obtain at the end of the stopping time a theoretical value of the thermal parameter close to the value.
- the heat flux supplied to the engine may also be considered to be a heat flux entering the engine, and the dissipated heat flux may be considered as being a heat flux leaving the engine.
- the heat flux supplied to the engine 1 by its operation is considered as zero because the latter is at a standstill.
- the temperature of the engine 1 will gradually fall by evacuating the calories accumulated by the engine 1 through a heat exchange in particular with the surrounding air of the engine 1.
- the simulation step may include a step of determining the evolution of the ambient air temperature during the downtime.
- This approximation of the evolution of the ambient air temperature can be made from the ambient temperature at the beginning of the stopping time and the ambient temperature at the end of the stopping time (these values being able to be those determined previously, and in particular stored in a memory).
- the approximation is carried out by linear approximation, or by exponential approximation (for example by exponential decay considering that during the stopping time the temperature decreases), or by calculating an average between the ambient temperature at start of downtime and ambient temperature at the end of downtime.
- Such approximations and calculations are well known to those skilled in the art and will not all be detailed here.
- an approximate temperature Tapp at time t, between t1 and t2 defining the stopping time (t1 being the start time of the stopping time and t2 being the instant of the stopping time). end of stop time), can be from the following formula:
- the heat flux 0 s (t) dissipated from the engine at time t is determined from the following equation:
- 0 s (t) h (t) .S. (T ° motor (t) - T ° ext (t)), equation (2) with h (t) the coefficient of heat exchange between the motor (for example considered as a metallic mass) and the air under a bonnet of the vehicle at the instant t, S the exchange surface between the engine 1 and the air under the bonnet, T ° engine (t) the temperature of the engine 1 (especially its metal mass) at time t, T ° ext (t) the temperature of the ambient air at time t.
- the engine hood is generally formed by a body member protecting the access of the engine to the front or rear of the vehicle.
- T ° ext at time t is derived from the approximation described above.
- h (t) is associated with the natural air / metal convection coefficient with air.
- the estimator 2 can be used so as to determine the temperature at a given point P of the engine 1, in particular taking into account the operation of the engine 1, in order to optimize the rise in temperature of said engine 1 .
- This optimization advantageously makes it possible to reduce the emissions of pollutants, for example by promoting chemical reactions in exhaust after-treatment devices of the engine.
- This optimization also reduces the fuel consumption of the engine, for example by increasing the speed of temperature rise of the engine, which reduces engine friction.
- This optimization may possibly also make it possible, in particular for diesel engines, to reduce the noise of cold running of the engine
- the method may comprise successively the initialization step E1 of the estimator 2, an estimation step E2 by the initialized estimator 2 of the temperature of the given point P of the engine 1 and a control step E3 of the circuit cooling circuit configured to limit the cooling of the given point P of the engine 1 if the estimated temperature of the given point P is below a predetermined threshold and / or for a predetermined time.
- the control step E3 makes it possible to control the various elements of the cooling circuit in order to reach the nominal operating temperature of the motor as quickly as possible.
- step E2 the engine is started, this implies that its operation induces a contribution of calories in particular because of the combustion of the engine fuel.
- FIG. 3 gives a particular example of implementation of the estimation of this temperature of the given point P by means of the initialized estimator 2.
- estimator 2 has at least three inputs and one output. The three inputs are used to feed the estimator with the following data: the parameters of the vehicle En1 (for example the engine speed and / or the engine load and / or the speed of the vehicle), the ambient temperature En2, and the temperature of the vehicle. initialization En3 (that is to say the evaluated thermal parameter).
- the estimator 2 gives an estimate of the temperature at the given point P of the engine 1.
- the predetermined threshold will be used to check whether this control step E3 must be stopped or continued.
- the use of this threshold to condition the execution time of the E3 control step is preferred because it allows a power consumption of the powertrain in the sense that cooling by a cooler is limited to the strict needs of the engine (unlike "standard” operation where the chiller is always maximum, for a given engine speed, whatever the engine needs).
- the limitation of cooling to the strict requirements of the engine also allows the latter to rise more quickly temperature, resulting in a reduction of friction and gains in fuel consumption and pollutant emissions.
- the estimation step E2 of the temperature of the given point P may comprise the following steps: determining a heat flux supplied (for example calories) to the engine 1 at the given point P due to the operation of the engine as a function of the evaluated thermal parameter (the thermal parameter is preferably used only to initialize the estimator at delivery when the engine is running, once the engine is running, it is no longer used), and to determine a dissipated heat flow (for example calories) of the engine 1 at the given point P.
- the heat dissipated flow of the engine can be determined according to the formula of equation (2) above.
- the coefficient h (t) can be determined (by calculation or by reading in a table) to from an operating point of the vehicle (engine speed and / or engine load and / or vehicle speed, etc.).
- the ambient temperature is supplied continuously to the input of equation (2), in particular by the sensors referred to above.
- the determination of the heat flux supplied to the motor and the determination of the dissipated thermal flow of the motor can each implement a step of estimating these flows from reading data in tables resulting from measurement and / or simulation. performed during a calibration of the operation of the powertrain of the vehicle. For example, they can be determined from a table taking as input: the engine and vehicle parameters (for example the engine speed and / or the engine load, and / or the vehicle speed, etc.); one or more temperatures calculated by the estimator, particularly at the given point; and an outside air temperature to the engine.
- the engine and vehicle parameters for example the engine speed and / or the engine load, and / or the vehicle speed, etc.
- the estimator 2 cyclically estimates the temperature at the given point P, in particular from the following formula:
- Fentrant-Fsortant MnxCpxDeltaT, equation (3) with the Fentrant given heat flux, F ant outputs the dissipated heat flux, Mn thermal inertia at the given point, Cp the thermal capacity at the given point P and the Delta T temperature variation at the given point P, so as to verify whether the step E3 configured to limit the cooling of the engine 1 must be continued.
- the engines are cooled by a cooling fluid circulating as close as possible to the zones of the engine to be cooled.
- the step E3 configured to limit the cooling of the engine 1 implements a step of stopping, or limiting, the circulation of a cooling fluid of the engine 1.
- the estimator 2 is configured so as to estimate over time the temperatures respectively associated with different given points P of the engine 1.
- the evaluation step E1 -3 of the thermal parameter is carried out so as to evaluate a temperature for each given point P of the engine 1 in order to initialize the estimator 2 with an initialization temperature for each given point of said motor 1.
- the estimator 2 may comprise calculation blocks (B1 to BN). These N calculation blocks, for N given points, are preferably constituted in the same way.
- the parameters, data and tables used may differ from one block to another.
- Figure 5 illustrates in more detail a calculation block.
- a Rm engine speed value and a Cm engine torque value enable from a combustion flow table Tf (for example calibrated by tests or by calculations) to determine the heat flux supplied to the engine at level of the given point P modeled by a thermal inertia associated with a metal mass Mn representative of the given point P to be monitored.
- the value of this metal mass Mn can be determined by tests or by calculation.
- the dissipated thermal flux 0 S of the thermal inertia (here represented ft2) is calculated at all times, in particular by the equation (2) described above.
- the coefficient h (t) varies according to the speed, in other words, this coefficient can be determined from a table taking as input the value of the vehicle speed V1 and giving in output h (t).
- the temperature of the thermal inertia is placed at the evaluated temperature Ti during the initialization phase. Then, for future estimates the equation (3) described above is used.
- an engine calculator can estimate the temperature S T at the given point N to be monitored, which corresponds to the temperature at the thermal inertia M N. This temperature can then be compared (out of "Estimator"), at any time, at the engine reliability threshold (s) corresponding to point N.
- the calculation can also be performed every y engine revolutions, being between 0.5 and 50 engine revolutions, and preferably y is equal to 1 motor revolution.
- the given points P are points associated with "fusible" zones of the cylinder head of a motor 1, it is therefore preferable to know their temperatures in order to act appropriately on the cooling of the engine 1 and thus avoid create irreparable damage to the engine 1 powertrain.
- the method described above makes it possible to best estimate the temperature at the start of the engine 1 without using specific sensors (for example located at the given points P of the engine 1 to directly measure the temperature) or additional to the technical definition. current vehicles.
- the combined use of the on-board clock to measure the elapsed time (downtime) and one or two air temperature sensor (s) (rearview mirror and / or in the engine via a sensor). temperature air flow meter) to know the ambient temperature allows to implement at least in part the method as described.
- the estimator 2 is initialized with temperatures true to reality as soon as the powertrain is restarted. This improves the accuracy, so also the gains in pollutant emissions compared to the prior art.
- the method can be implemented using components already present in a motor vehicle. Thus, it is simple to implement and does not generate significant additional cost.
- this lump-sum temperature is chosen so as to overestimate the temperature of the given point associated in order to protect it.
- the invention also relates to a data storage medium readable by a computer, on which is recorded a computer program comprising computer program code means for implementing the steps of the method as described.
- a computer program may include a computer program code means adapted to performing the steps of the method as described when the program is executed by a computer, including the supervision computer 3 referred to above.
- a device may comprise hardware and / or software elements for implementing said method. More particularly, these hardware and / or software elements for implementing the method may comprise: an element for determining a stopping time of a powertrain element; an element for determining at least one value representative of the temperature of the ambient air; an evaluation element of a thermal parameter of the motor as a function of the determined stopping time and the value representative of the determined ambient air temperature; and an initialization element of the estimator from the evaluated thermal parameter.
- These various elements can be controlled by a computer, in particular the supervision computer 3, in order to implement the method.
- a motor vehicle may comprise a computer configured to implement the method as described and / or the device mentioned above interfaced with the computer.
