Definitions
- the present disclosure relates to a method for estimating the atmospheric pressure for an internal combustion engine.
- the present disclosure relates to the field of the management of internal combustion engines, in particular in the automotive field in the broad sense, that is to say any type of vehicle moving on the road such as an automobile, a motorcycle, a truck, etc powered by an internal combustion engine.
- the document EP2037108A2 relates to a method for acquiring and processing an intake pressure signal in an internal combustion engine without an intake manifold, the internal combustion engine having at least one cylinder which receives the fresh air through an intake duct, which is controlled by a throttle valve and which includes a pressure sensor connected to an electronic control unit.
- the following steps are performed: determining a start angle and an end angle of a measurement window which depends on the engine speed, measures, via the pressure sensor, the instantaneous induction pressure at a plurality of different crankshaft angles distributed in the measurement window; determination of a compensation factor depending on the speed of the engine and the position of the throttle valve, and determination of the atmospheric pressure by applying the compensation factor to the average of the instantaneous induction pressures measured in the window measurement.
- This disclosure improves the situation. Its purpose is in particular to provide a method making it possible to rapidly determine an atmospheric pressure.
- the determination method will require few computing resources at the level of the electronics associated with the engine.
- the method can be used both at low load and at high load.
- a method for determining the atmospheric pressure for a combustion engine comprising at least one cylinder supplied with air by an intake device comprising a butterfly valve and at least one air intake valve in said cylinder as well as a pressure sensor measuring a pressure prevailing between said butterfly valve and said at least one intake valve, said method comprising the following steps:
- said method further comprises a step of measuring a second pressure supplied by the pressure sensor at a predetermined time interval after the measurement of the first pressure, said time interval corresponds to a multiple odd of a half-period of a pressure pulsation which can be observed by said pressure sensor during an admission of air into the engine, and an average pressure corresponding to the average of the first pressure and the second pressure is used to determine with the other possible parameters the atmospheric pressure.
- This method is based on the original finding that the pressure pulsations visible by the pressure sensor have a constant period, said period depending solely on the structure of the engine. This period thus does not vary for a given engine and is the same for similar engines. Thus, the average of two measured values makes it possible to obtain the average pressure over the entire pulse. In this way, an estimate of the atmospheric pressure is obtained quickly and at little cost in terms of computer resources.
- the measurement of the first pressure is carried out between 90° CRK and 0° CRK before a top dead center called a crossover top dead center for which said at least one intake valve as well as a corresponding exhaust valve are open;
- the time interval between the measurement of the first pressure and the measurement of the second pressure corresponds to a half-period of the pressure pulsation which can be observed by the pressure sensor during an air intake in the engine;
- said method further comprises a step of first-order filtering of the determined atmospheric pressure.
- the present disclosure also relates to a computer program comprising program code instructions for the execution of all the steps of a method described above, when said program is executed on a computer, in particular an electronic control unit of an internal combustion engine.
- the present disclosure also relates to a computer-readable recording medium on which a program according to the preceding paragraph is recorded.
- the present disclosure also relates to an internal combustion engine comprising:
- an intake device comprising a butterfly valve and at least one air intake valve in said cylinder as well as a pressure sensor measuring a pressure prevailing between said butterfly valve and said au least one inlet valve
- an electronic control unit characterized in that the electronic control unit is configured for:
- Such an engine may include several pressure sensors arranged between a butterfly valve and an intake valve.
- the pressure measurements for determining the atmospheric pressure are advantageously carried out with a single one of said pressure sensors.
- FIG. 1 schematically shows an internal combustion engine.
- FIG. 2 illustrates a method of determining atmospheric pressure according to the present disclosure on a pressure versus time reading curve of a pressure sensor of the engine of Figure 1.
- FIG. 3 shows a flowchart for a preferred embodiment of a method for determining atmospheric pressure in an internal combustion engine.
- FIG. 1 This figure very schematically illustrates an internal combustion engine 10.
- an engine comprises at least one cylinder 12 in which a mixture air/fuel burns to provide motive power transmitted to a crankshaft.
- An air supply device 14 is provided to supply the cylinder 12 with air.
- This device passes air from outside the engine through a butterfly valve 16 which makes it possible to regulate the flow of air supplying the cylinder 12.
- the air inlet into the cylinder 12 is controlled by at least an 18 valve (it is common to have two intake valves per cylinder).
- a pressure sensor 20 is present in the air supply system 14 between the butterfly valve 16 and the valve(s) 18. Subsequently, for simplicity, a single valve 18 will be mentioned for admission even for scenarios with several intake valves per cylinder.
- the pressure sensor 20 is first of all used to know the pressure of the air (or of an air/fuel mixture) just upstream of the cylinder 12 and thus to be able to determine the quantity of air which enters cylinder 12 for each combustion.
- Such a pressure measurement by the pressure sensor 20 is most often carried out before the engine passes through a crossover top dead center, that is to say a passage to a top dead center when the valve d intake and exhaust valve are open, for example between 90° CRK (i.e. 90° of rotation, measured on the crankshaft of the engine under consideration) and 0° CRK, preferably about 60° CRK before crossing top dead center.
- a crossover top dead center that is to say a passage to a top dead center when the valve d intake and exhaust valve are open, for example between 90° CRK (i.e. 90° of rotation, measured on the crankshaft of the engine under consideration) and 0° CRK, preferably about 60° CRK before crossing top dead center.
- FIG. 2 illustrates pressure variations that can be measured by a pressure sensor 20 in an intake manifold as a function of time t in seconds (s).
- V voltage variations in volts
- the method proposed by the present disclosure is based on the original observation that the frequency of the pressure pulses measured by the pressure sensor 20 depends only on the structure of the engine, or more particularly on the air supply device 14. Let P (for example in milliseconds (ms or 10(exp-3) s) be the period of these pulsations. By taking a first pressure measurement then a second pressure measurement at an interval of P / 2, the average value of the two measurements taken corresponds to the mean value of the pressure on the pulse.This value is therefore independent of the position of the pressure measurements on the pulse.
- FIG 2 the pressure variations measured by the pressure sensor 20 are illustrated.
- a MAP pressure measurement is made when a piston in cylinder 12 is at its bottom dead center at the end of the intake phase in cylinder 12. It is at this time that the pressure measured by pressure sensor 20 at the course of the considered combustion cycle is the lowest.
- This pressure value is representative of the mass of air introduced into the cylinder 12. It is important for the management of combustion but is not concerned by the present disclosure.
- a first pressure MAP_UP is measured at a predetermined position of the engine, shortly before the start of an air intake phase in the cylinder 12, for example 30° CRK before the passage of the cylinder 12 piston at crossover top dead center.
- a pressure measurement providing a second pressure MAP_UP_T is carried out X ms after the measurement having provided the pressure value MAP_UP.
- X P/2.
- This method proposed here is for example implemented by a central unit 22 of the engine.
- This central unit 22 notably contains a microprocessor and a memory. It is connected to various engine components. It receives data from sensors, performs calculations based on the data received and provides control instructions to controllable components.
- the central unit 22 permanently knows the angular position of the engine (expressed in ° CRK corresponding to the angular position of the engine crankshaft over 720° in the case of a so-called four-stroke engine).
- a pressure measurement is taken and delivers a first pressure value MAPJJP.
- the central unit also incorporates a clock and commands the pressure sensor 20 to make another pressure measurement X ms after the measurement that provided the first value MAP_UP. A second pressure value MAP_UP_T is then obtained.
- the value X corresponds to the half-period of the pulsations of the pressure prevailing between the butterfly valve 16 and the valve 18. This value (X) is fixed. It depends on the structure of the engine and is stored in the central unit 22.
- the next step provides a value MAP_AV which corresponds to the arithmetic mean of the first pressure value MAP_UP and of the second pressure value MAP_UP_T, i.e.:
- MAP_AV (MAP_UP + MAP_UP_T) / 2
- this average pressure value (MAP_AV) was obtained. This value will only be retained if it can be representative of the atmospheric pressure, that is to say if the part of the air supply device downstream of the butterfly valve 16 has been able to balance, or tend to s balance, with the part upstream of this butterfly valve 16. Thus for high engine speeds N, the value MAP_AV will be retained if the opening value TPS was sufficiently large. At low engine speed N, valve opening TPS values butterfly 16 weaker may be accepted.
- the conditions for taking into account the average value MAP_AV thus depend both on N (engine speed) and on TPS (value, or angle, of opening of the butterfly valve, in percentage or in degrees).
- the value MAP_AV is retained, then it is possible to determine a new estimate of the atmospheric pressure AMP_NEW as a function of this average value. This determination is made according to the speed N and also the opening value of the butterfly valve. Indeed, as can be seen from the above, the lower the speed N, the closer the pressure MAP_AV approaches atmospheric pressure since the downstream pressure has more time to equilibrate with the pressure upstream of the butterfly valve 16. Similarly, the higher the value of TPS, the lower the pressure drop through the butterfly valve 16 and therefore the closer the value of the downstream pressure is to the upstream pressure of this valve.
- FC which is a function of the two variables N and TPS.
- AMP_NEW FC(N,TPS)*MAP_AV
- the atmospheric pressure varying slowly it is proposed to provide a filtering step (Filt) to filter the estimated values AMP_NEW and obtain a final value of the atmospheric pressure.
- the method proposed by the present disclosure is a reactive and precise method. It allows you to quickly obtain an atmospheric pressure value very close to the real value. This process also works when the engine load is low. It is also not dependent on the engine speed: the first measurement is made at a predetermined engine position and the second measurement is made at a fixed time interval with respect to the first measurement.
