Definitions

the present invention relates to a method for controlling the regeneration of a trap for polluting substances emitted by a internal combustion engine fitted to a motor vehicle or road.
the present invention also relates to a system for the implementation of this method.
a solution to regenerate such a particulate filter is to operate the combustion of the particles trapped therein. To provoke the combustion of the particles, it is necessary to bring them to temperatures of at least 550 ° C. Given the conditions vehicles, the exhaust gases of diesel engines naturally only rarely reach these temperatures. Thus, in urban traffic, the temperatures of Exhaust gases generally evolve between 150 and 250 ° C. Born so can count on a natural regeneration of the filter, it must therefore cause the increase of the temperature of the gases exhaust to burn the particles in the filter and therefore have the appropriate means for that. increasing of exhaust gas temperature is achieved in the motors and / or at the level of particulate filters.
the increase of the temperature of the exhaust gases in the engines is, by example, obtained by the post-combustion of a certain amount of fuel injected late in the cycle.
the increase in exhaust temperature in the particulate filters is it, for example, obtained by electric heating means located upstream or inside the filters.
This induced increase in the temperature of the gases exhaust to burn the particles is operated periodically according to predetermined strategies.
the regeneration of the heating means can be operated simply every X kilometers, or even when a quantity predetermined particle has been trapped in the filter or as long as the gap between the downstream gas pressures and the pressure upstream of the filter exceeds a threshold value predetermined ...
the regeneration operation leads to overconsumption of fuel compared to normal operation of the engine, whether directly, by the afterburning of a certain amount of fuel, or that or indirectly, by consuming a certain amount of fuel to provide the engine with extra power necessary for production the energy consumed by the means regeneration assistance type electric heating or other.
the present invention therefore proposes to optimize the the traps and in particular the timing of regeneration and this, to limit overconsumption of engines related to these pitfalls.
the control method according to the invention relates to regeneration a trap for polluting substances emitted by a combustion engine internal combustion equipping a motor vehicle or road.
This control method is intended to control the operation of means of periodic regeneration of the trap by eliminating the substances that are trapped there.
control method is characterized in that that the moment of initiation of the regeneration is chosen from to limit the duration of the regeneration and to limit the overconsumption of said engine generated by the trap, the choice of moment being based on the knowledge of past conditions of operation of the said vehicle since the last regeneration and on the estimation of future conditions of operation of said vehicle, these future conditions being provided by means of predictions of the operation of the vehicle.
the moment of regeneration is defined in the form number of kilometers to be traveled by the vehicle from the last regeneration.
the means for predicting the future operation of the vehicle include a navigation system and / or radio-traffic type systems capable of determining the path of said vehicle and / or traffic conditions to come.
said future operating conditions are deduced from the operating conditions previously encountered by said vehicle.
determining the timing of regeneration consists of to look for a first optimal theoretical moment of regeneration that minimizes overconsumption of fuel from motor, then to search on both sides of the first moment, within a predetermined interval, a moment that allows for rapid regeneration, the latter being then the moment chosen to trigger the actual regeneration of the trap.
the operating conditions of the vehicle are modeled as a finite number of rolling types, to each type of rolling corresponding to the beaches of operation defined by the values taken by quantities appropriate features such as vehicle speed and torque engine.
each type of rolling is associated a distance of regeneration optimizing overconsumption in fuel and a corresponding regeneration time.
the past and future operation of the vehicle is found expressed in the form of a succession of sections, each section being defined by a given type of rolling and a characteristic data item such as its length. in number of kilometers.
the length of the interval considered around the theoretical optimal regeneration moment for determining the effective moment of regeneration is less than or equal to substantially 30% of the distance corresponding to the theoretical optimum moment. regeneration.
FIG. 1 shows a diesel engine of the type equipping a motor vehicle, engine designated by the reference general 1, this diesel engine being equipped with a particulate filter 7. It is obvious that the present invention is not limited to this only type of engine or only this application to vehicles cars or even this type of trap but concerns all internal combustion engines regardless of their types and regardless of their applications and this, as far as the operation of these motors causes the emission of compounds pollutants which require for their treatment their trapping in an appropriate trap and the periodic regeneration of this last.
the diesel engine 1 is associated with air intake means entry of the latter, which are designated by general reference 2.
output, this engine is associated with an exhaust line that is designated by the general reference 3.
Means for recycling exhaust gas from the engine entry of it are also provided and are designated by the general reference 4.
the exhaust line can also be associated with a turbocharger designated by general reference 5 and above particularly to the turbine portion thereof, so classic.
the exhaust line comprises an oxidation catalyst designated by the general reference 6, disposed upstream of a filter to particles designated by general reference 7, arranged in the line exhaust.
the engine is also associated with a fuel system common example in fuel cylinders thereof.
This system is designated by the general reference 8 in this figure and comprises, for example, high-pressure injectors with control associated with these cylinders.
the motor is an engine four-cylinder and therefore has four controllable injectors 9,10,11 and 12 respectively.
injectors are associated for example with a ramp common fuel supply designated by reference 13 and connected to fuel supply means designated by the general reference 14, comprising for example a high pressure pump.
These supply means are connected to a fuel tank designated by the general reference 15 and for example to means adding to this fuel an additive intended to be deposited on the filter with particles to lower the combustion temperature of particles trapped in it.
this additive can for example be contained in a reservoir auxiliary designated by the general reference 16 associated with the reservoir fuel 15 to allow the injection of a certain amount of this additive in the fuel.
this engine and the various organs that have just been described are also associated with means of controlling their functioning designated by general reference 17 on this figure, comprising for example an appropriate calculator 18 associated with information storage means 19, and connected in input to different means of acquiring information relating to different operating parameters of this engine and these bodies, this calculator then being adapted to control the operation of the admission means, recycling means, turbocharger and / or fuel system for check the operation of the engine and in particular the torque generated by it depending on the driving conditions of the vehicle in a classic way.
this calculator is connected to a sensor of differential pressure across the catalyst and the filter particles, respectively 6 and 7, to one or more sensors of temperature 21, 22 and 23, respectively upstream of the catalyst, between this catalyst and the particulate filter and downstream of this filter to particles in the exhaust line.
the pressure sensor 20 can also be connected to the terminals of the filter alone.
the calculator can also receive a content information oxygen exhaust gases from a Lambda probe designated by the general reference 24 in this figure, integrated into the exhaust line.
this calculator is adapted to pilot the means air intake, means for recycling exhaust gas, the turbocharger, the means for adding fuel to the additive, the fuel supply means of the common rail and the different injectors associated with the engine cylinders.
this calculator is adapted to trigger a regeneration phase of the particulate filter by combustion of particles trapped in it by engaging a phase multiple injections of fuel into the engine cylinders during their relaxation phase.
the particles emitted by the engine during its operation are indeed trapped in the particulate filter. he it is then necessary to regenerate it regularly by combustion of these particles.
the control means 17 are also associated with means determining the activation state of the oxidation catalyst 6 formed by the calculator 18 thereof, for, during the regeneration of the filter, to continuously adapt the conditions of unfolding of the phase of multiple fuel injections in the engine cylinders to account for the activation status catalyst.
Continuous monitoring of the activity level of the catalyst allows to control continuously phasing and / or amount of fuel injected to continuously optimize the operation of the catalyst and therefore the temperature within this catalyst avoiding any degradation thereof, the filter to particles or the engine and any production of fumes or odors.
the activation state of the catalyst 6 can be determined by the calculator 18 for example from the information delivered by the temperature sensors 21 at the catalyst inlet and 22 in exit from it, in a classic way.
the computer 18 is associated with a modeling integrated digital catalyst to know its state of activity from the information provided by the sensors.
This regeneration is performed by post fuel injection.
This post-injected fuel will ignite late and burn in the exhaust line and thus cause the filter right the combustion of soot.
the time required to operate the combustion soot trapped in the filter and therefore the amount of fuel to be post-injected is directly dependent on the point of motor operation and in particular the temperature of the exhaust gas.
the regeneration operation is, can not be triggered either, can be but with more or less overconsumption important in fuel.
the presence of a particle filter therefore constitutes in itself a significant potential source of overconsumption of the engine.
the present invention therefore proposes to control the operation of the filter and in particular the regeneration phase of the filter particles not taking into account the only degree of filling the filter as in the prior art, but taking mainly accounts for the overconsumption of the engine generated by the operation of the filter in order to limit as much as possible the importance of such overconsumption.
the present invention proposes more precisely to find a optimum between too frequent regenerations that would induce a high overall motor overconsumption linked to many post-injections and regenerations would also induce overall overconsumption of the engine high due to strong exhaust backpressures.
Optimization of the regeneration strategy therefore consists in choose at best the triggering of the regeneration phases.
supervisor constituted by a software program executed by the engine control computer 18.
the supervisor receives via the calculator 18 information about conditions vehicle use and engine operation as for example its speed, the position of the accelerator pedal, the rotational speed of the engine, etc. These different informations input of the program are analyzed and at the output, the supervisor triggers and controls the regeneration phases of the filter.
the supervisor may consist of mainly of three modules.
a first driving module called NR for Necessity of Regenerating, more particularly to function to know the level of soot load of the filter and its consequences on the operation of the vehicle in terms of fuel consumption.
a second module called CR for Capacity to Regenerate, evaluates the efficiency of a regeneration demand under the conditions of current or future engine operation.
a third module called D, to Decide exploits the information received from the first two modules and triggers the regeneration phases by minimizing the impact on the engine consumption and in critical cases ensures safety operating the filter and the motor.
the first module NR is itself composed of two sub-modules.
the first submodule NR_MCF provides the level of charge of the particulate mass filter carbon only. It is a question of respecting the specifications of the supplier of the ceramic forming the filter body and in particular the maximum allowable carbon load in order not to not damage the filter during critical regenerations ie low flow rate and high soot mass.
the output indicator of this sub-module must characterize different states of charge ranging from the state "empty" to the state "maximum load.
the second submodule of the NR module is the submodule NR_MS which provides the optimal distance of regeneration, evaluated to count from the last regeneration to date.
the regeneration distance optimum will vary regularly depending on the driving conditions encountered by the vehicle.
the output indicator of the module should characterize the optimal regeneration distance of the filter and the situation of the vehicle with respect to this optimum.
the second module CR is also composed of two sub-modules.
the first sub-module CR_MCT characterizes the regeneration capacity under the conditions current engine utilization and one of the output indicators of the module is so the success rate of a possible regeneration performed under the present conditions and the second submodule CR_MLT characterizes the regeneration capacity to come and the output indicator is therefore the probability of meeting conditions more favorable to regeneration than the conditions present.
the areas of use of the vehicle and the engine have been segmented into a predetermined number N of types of rolling Ri (with i ranging from 1 to N).
N a predetermined number of types of rolling Ri
the operating domain of the engine was broken down into 5 types of rolling and the parameters selected to characterize these types are the driving torque and the vehicle traveling speed.
N being more or less important according to in particular the computing capabilities of microprocessor equipping the computer 18, the same parameters used to characterize the types of operation can be more or less numerous, one could for example take into account the engine speed, the temperature of the cooling, etc.
Each type of rolling Ri is therefore defined so as to correspond to a substantially homogeneous operation vis-à-vis particle filter.
the optimum distance DistOptRege Rj regeneration minimizing the overconsumption associated with the regeneration phase filter is then determined (assuming the engine operates in steady state steady state within this type of regeneration). rolling). This distance is defined from the end of the last regeneration performed on the filter.
DistOptRege distance is determined by relative to the filling of the filter.
the regeneration time of the filter DureeRegeOpt Rj when it is initiated at the optimum distance of regeneration DistOptRege Rj, is also determined .
the regeneration time of the filter DureeRegeOpt Rj when it is initiated at the optimum distance of regeneration DistOptRege Rj, is also determined .
the sub-module CR_MCT has the particular function of characterize the operation of the engine and the vehicle and to identify in which type of rolling Ri it is. From information received from the different sensors, the CR_MCT module periodically calculates the value of the type of taxiing where the engine, this raw value is then filtered to eliminate the transient. The result is the information that the vehicle is finds at the moment in a type of rolling of Ri operation given. The module CR_MCT calculates moreover the distance traveled in each type of driving.
the types of rolling thus determined are memorized and accounted for from the last regeneration observed in order to constitute a history of the types of driving followed by the vehicle.
the operation of the vehicle and the engine is found thus represented in the form of a succession of sections each section being characterized by a length in number of kilometers and a type of taxiing given. Good obviously other quantities could be taken into account to characterize a stretch like the rolling time.
M which is the number of sections encountered successively by the vehicle and the engine since the last regeneration up to the present moment regularly grows as as the vehicle is used, until the moment of the new regeneration which then resets the counters.
the sub-module CR_MLT has more particularly its function to predict in a predictive way the sections to come, that is to say those intended to be encountered during the present journey of vehicle or future journeys.
This sub-module CR_MLT uses the results of the submodule CR_MCT that it processes statistically and / or information provided by an on-board navigation system on the vehicle.
the calculator 18 is adapted to build a history of conditions of use of the vehicle and to trigger the storage of it in the means 19.
This history makes it possible to calculate the probability of meeting conditions of use of the vehicle more favorable than the current conditions of use.
This statistical information on the conditions of use of the vehicle give an indication of the advisability of postponing not triggering regeneration.
a statistical indication favorable authorizes a postponement of this trigger in the event that short-term conditions would not be favorable.
a navigation system 30 is for example of the type suitable for provide an itinerary after entering the place of destination or when this destination is otherwise known and to guide the motorist along this route using for example the GPS technology.
Such a device specific or integrated with a radio apparatus, may also be able to receive information on road traffic and on circulation in order to refine its guidance.
This system of navigation is therefore adapted to communicate to the engine control information on the nature of the journey and the conditions of circulation to be transcribed into types of taxiing. engine operation.
the CR_MLT module is able to predict on a predetermined horizon, the conditions of vehicle circulation and engine operation. It is then able to discretize this horizon in the form of a succession of elementary sections T k each corresponding to a given type of rolling of the vehicle.
This discretization can, for example, be expressed in the form of the following series of sections (taking as a reference the current position of the vehicle): section T M + 1 : over 10km circulation in rolling type R 1 , section T M +2 : over 25km traffic in rolling type R 3 , T M + 2 : 50km in rolling type R 5 , T M + 4 : again 5 km in rolling type R 1 , etc.
the time is determined the lowest and then determine the optimal distance of regeneration as the one corresponding to the instant of triggering the regeneration that caused this most low.
the optimal distance of regeneration it is the one who have start or end time closest to the optimal distance of theoretical regeneration that will be preferred and the optimal distance from actual regeneration will be defined from it.
