Definitions
- the present invention relates to a method for identifying the emission thresholds of polluting gases to control the operation in "Stop and Start” stop an engine just before and during the immobilization of a vehicle automobile, and restart it instantly at the first driver's request.
- the system “Stop and Start” is a system that stops the engine just before and during the immobilization of the vehicle (traffic lights, traffic jams, etc.). The system starts automatically and instantaneously as soon as the brake pedal is released by the driver, when the driver wants to restart.
- the emission thresholds may be, for example, the thresholds defined by the EOBD.
- the European On Board Diagnosis (EOBD) is a European regulation accompanying the EURO 3 standard.
- the purpose of the EOBD is to inform the driver via the engine diagnostic LED of any fault affecting the clearance by exceeding a threshold.
- the EOBD is a monitoring software integrated into the engine control computer, it has two main functions: to detect the failures of the emission control equipment of the vehicle, and to signal to the driver the failures that result in exceeding an emission threshold, so that he can have the vehicle repaired.
- the object of the present invention is to limit the impact of these stops / restarts on the emissions of gaseous pollutants, such as HC, CO and NOx.
- the quantity of fuel injected is calculated on each restart, b) the difference between the quantity of fuel injected and the amount of normal fuel required is determined, the said resultant amount being considered to represent the quantity of fuel injected but not burned, c) comparing said injected but unburned fuel quantity with a predetermined threshold value, as a function of the distance traveled, d) inhibiting or not the operation in "Stop and Start” mode according to whether said quantity of fuel injected but not burned is greater than or not the predetermined threshold value.
- the calculation of the amount of fuel injected but not burned is an iterative calculation and by summation, so as to calculate the sum of fuel quantities injected but not burned for a series restarts between two engine restarts using the ignition key.
- each time the traveled distance counter returns to zero the value of the sum of the fuel injected but unburned amounts is reset to a value obtained by difference between said sum just before reset and a predetermined threshold value, when this difference is positive, and reset to zero when said difference is negative.
- the method is repeated over at least three driving cycles, and it comprises, in addition, the following step: a) storing each excess of said quantity of fuel
- FIG. 1 is a graph representative of an emission threshold according to the EOBD as a function of the distance traveled (also referred to as the "EOBD threshold” template) since the activation of the ignition contact by the ignition key. contact.
- Figure 2 is a graph representative of the evolution of the level of the restart quality indicator parameter, according to the present invention, which level of said parameter controls the setting or not in "Stop and Start” mode of the engine.
- a restart quality indicator is defined, as explained hereinafter. after.
- the motor may or may not operate in "Stop and Start" mode.
- the present invention on each restart, it calculates the amount of gasoline injected and is compared to the nominal amount of fuel required. The difference between these two quantities is considered to be gasoline which has been injected and which has not burned, and which consequently finds itself in the exhaust. This quantity is then compared with the level of unburned hydrocarbons (HC), a "fat polluter” limit as a function of the distance traveled. Depending on the result of this comparison, the "Stop and Start" function is inhibited or not, as will be explained later.
- HC unburned hydrocarbons
- Each cycle, between two starts with the ignition key, comprises a series of startups and reboots, which can be named 1, 2, .., i, ...
- the template "Threshold EOBD” is defined by three parameters, namely InitEOBD, DistEOBD and slopeEOBD calibrated. It has the shape shown in the drawing of Figure 1 according to said distance traveled.
- the curve has an initial flat section which is intended to allow the "Stop and Start", even after a difficult first start. It is parameterized by "InitE ⁇ BD" on the ordinate axis or axis of the EOBD and "DistEOBD” thresholds on the abscissa axis or axis of the distance traveled. Then, the slope (PenteEOBD) makes it possible to guarantee the respect of the criterion of the EOBD standard.
- the value of PenteEOBD is that of the line segment joining the origin O to the set point of coordinates InitEOBD and DistEOBD. The origin O corresponds to the start with the ignition key.
- the counter Sum Ti is reset to the value A, which corresponds to the same value A representing the difference between the Sum value.
- Ti and the threshold value E oBD at first maximum distance traveled Dl At the second reset illustrated by the arrow F2, the difference B between the value of Sum Ti and the template ThresholdEOBD being negative, the initialization is then zeroed in D2 (second distance traveled max.).
