Definitions
- the present invention relates to a method for estimating in real time the instantaneous speed produced by each cylinder of an internal combustion engine from the instantaneous speed sensor located at the end of the transmission.
- an instantaneous speed sensor is placed at the end of the transmission. This measurement is very distorted by the transmission and is noisy.
- a reconstruction of the cylinder to cylinder torque is indispensable.
- the implementation of a digital couplometer under each cylinder is unthinkable on vehicle given their cost.
- the method according to the invention proposes to define an estimator operating from the measurement at the end of the transmission chain to estimate the instantaneous speed under each of the cylinders.
- the method of the invention relates to a method for estimating in real time the instantaneous speed produced by each of the cylinders of an internal combustion engine comprising at least one transmission system connected to the cylinders and a sensor that realizes in real time. a measurement (x ⁇ ) of the instantaneous speed at the end of said transmission system.
- FIG. 1 illustrates the estimation of the instantaneous speed under the cylinders by the method according to the invention, on an operating point of 1250tr / min average load.
- the method consists mainly of the following four steps:
- This equation (2) constitutes the physical model representing in real time the dynamics of the transmission system.
- An estimation of the signal W 0 makes it possible to determine an estimate of the signal XQ from equation (1).
- the dj represent the 2n + l Fourier coefficients of the decomposition of the signal XQ.
- a signal is thus defined translating the instantaneous regime Xo, as a function of the invariant parameters jt over time.
- variable change W 0 is also mechanically periodic, and its decomposition in Fourier coefficients, developed in complex for the clarity of the exposition, is written as follows:
- the C j represent the 2n + ⁇ Fourier coefficients.
- a non-linear adaptive-type estimator is defined, on the one hand, a term related to the dynamic and, on the other hand, a correction term:
- the system of equations (5) represents an adaptive-type non-linear estimator for estimating the coefficients c / of the Fourier coefficient decomposition of the signal W 0 .
- the estimator (5) makes it possible to reconstruct W 0 through its Fourier coefficients Cj.
- the objective is to reconstruct XQ.
- w 0 given by Equation (1), expresses the coefficients d j basis of the coefficients c, -:
- the knowledge of the average torque produced by each cylinder is a fundamental and relevant information for the estimation of the combustion; it is the image of the combustion that the engine sees.
- the previous estimator (5) allows us to estimate the signal of the regime under the cylinders but also its Fourier decomposition. However, the more torque is important the greater the excitement on the tree. In this sense it is possible to correlate the torque produced by the cylinder and the Fourier coefficients of the decomposition of the instantaneous regime signal (XQ).
- This function ⁇ can be a polynomial function. It can be determined empirically from test. For example we can choose the following function ⁇ :
- ⁇ 0 a constant to be calibrated according to the engine speed used using correlations with the engine bench measurements.
- This calibration can be done at from a tabulation, resulting from a linear optimization consisting of adjusting the value of ⁇ 0 so that the estimates are as close as possible to the engine parameters (parameters allowing the calibration of the engine and supplied by the manufacturer).
- FIG. 1 illustrates the estimation (R es t) of the instantaneous speed Xo under the rolls from the estimator according to the invention (5) previously described on an operating point at 1250rpm average load.
- Figure 1 also illustrates the reference instantaneous engine speed R ref (calculated from the cylinder pressure measurements on the test bench). We observe a very good estimate of the signal.
- FIG. 2 illustrates the estimation (PMI est ) of the cylinder-to-cylinder torque on an operating point at 1500 rpm, from the estimator according to the invention (5) and from a function ⁇ defined by the equation ( 7).
- Figure 2 also illustrates the average reference torque (PMI re f) (calculated from cylinder pressure measurements on the engine test bench). We observe a very good estimate of the signal.
- the adaptive filter thus produced is efficient, and above all does not require any additional adjustment in the case of change of the operating point. No identification phase is necessary, only a measurement and model noise adjustment must be carried out, once and for all A motor control can thus, from the reconstructed pairs, adapt the fuel masses injected into each of the cylinders so that the pairs are balanced in all the cylinders.
