Definitions
- the present invention relates to the field of control of thermal engines.
- a method of estimating the torque of a heat engine in a hybrid vehicle transmission comprising at least one heat engine and an electric machine together, or separately, a thermal torque and an electric torque in the direction vehicle wheels.
- This method is applicable to any thermal or hybrid GMP having two rotating shafts (or pinions), which must be synchronized to engage a transmission ratio.
- the torque control of a combustion engine on a hybrid vehicle or not is a key issue for improving the overall performance of the vehicle, and its driving pleasure.
- the gearbox associated with the engine is a parallel shaft box, comprising at least one primary shaft, connected to a power source, and a secondary shaft driven by the primary shaft to transmit the engine torque to the wheels, it requires good torque management (thermal and / or electrical), to avoid possible torque surges during torque recovery after gear changes. Controlling engine torque during gear changes is particularly important in some hybrid architectures, where the synchronization of the two box shafts, before the commitment of a report, is entrusted to the engine.
- the torque measurement of the engine is not directly available on a vehicle while driving.
- One means of disposing of its value is to estimate it (reconstituting it) indirectly from measurements of the rotational angular speed of the crankshaft.
- a method for measuring the torque of an internal combustion engine using the signal produced by a sensor associated with the rim of the flywheel This method makes it possible to calculate the average gas torque produced by each combustion of the gaseous mixture in each cylinder of the engine.
- the calculated values are used to continuously improve the operation of the motor, and to monitor the defects.
- the engine computer is able to adapt to the empirical measurements made on the steering wheel crown.
- the continuous improvement of the combustion performance is implemented by a loop control of the combustion parameters, which assumes a good knowledge of the dynamics of the combustion systems, and their response times.
- the purpose of the present invention is to reconstitute a torque signal produced by the combustion engine, holding account of its transmission to the shift control devices and the wheels.
- the estimated torque signal must be accurate enough to make the passages transparent to the users.
- the invention proposes to estimate the thermal torque, as the sum of an estimate of the total torque supplied by the transmission to the wheels, and an estimate of the overall resisting torque of the transmission.
- this method uses a measurement of the speed of the heat engine, the value of the torque setpoint of the heat engine, and the value of the torque of the electric machine.
- T th the torque of the heat engine
- the overall inertia of the GMP can be reduced to the engine, introducing the notions of "equivalent inertia", or “inertia reduced to the engine” Jeq-em, and resistant torque equivalent T res eq .
- the equivalent resistive torque can be the applied resisting torque to the wheel T r res or the resistant torque of the motor. From this equation, the invention proposes to construct an "observer" making it possible to establish, an estimate of the thermal regime cb th , an estimate T th , of the torque T h , applied by the heat engine, and an estimation of the torque resistant equivalent T ⁇ 5 , guaranteeing the "robustness" of
- the method is illustrated in FIG. 1. It makes it possible to estimate the torque of a heat engine in a hybrid vehicle transmission comprising at least one heat engine and an electric machine that together or separately provide a thermal torque Tth and an electric torque T. m in the direction of the vehicle wheels.
- the output signals cb th , T th , 7 ⁇ appear in FIG. 1, as well as the estimate of the total torque T.
- the estimated engine torque T th is the algebraic sum of T and 7 ⁇ .
- M 0 , M- L , / and fe 2 are the gains to be calibrated.
- a first gain Mo, or "derivative”, is assigned the sign of the difference (cot r ô) th ) to be added to the product aT em .
- the sign of xi is imposed on the second gain Mi, used to calculate the estimates of torque, T, T th and in the following steps.
- the term Mi.sign (xi) is added to the torque setpoint T t ⁇ to give, by integration, the estimate of the total torque T. It undergoes a double integration after having been successively multiplied by the inverse of the gain k 2 and by the inverse of the engine time constant ⁇ .
- the estimation of the equivalent resisting torque is obtained by multiplying the result by the inverse of the parameter ⁇ , mentioned above.
- the estimate of the torque of the heat engine T th is the sum of the estimate of the total torque T and the equivalent resistive torque 1.
- the observer has, that the speed measurement of the thermal engine o th , the setpoint of torque T t " J , and the electric machine torque T em .
- the equivalent resisting torque is multiplied by parameter / ?.
- the invention proposes a robust vehicle torque estimation method equipped with a thermal or hybrid GMP.
- the observer can estimate the torque applied to the engine Coordinate 1 ⁇ , the applied torque T and the total resisting torque empoweringT ⁇ 5.
- This estimate makes it possible to make the next step of coupling the two shafts (torque rebate or torque rocker) transparent, considerably reducing the torque jerk.
- the method notably makes it possible to better manage the tracking of the path of the torque during the synchronization of two shafts, by means of the heat engine.
- the convergence of the estimated speed (b th to the measured speed 0 th ) is not very sensitive to variations in the parameters of the system, such as the inertia and the response time of the actuator, or any delays, so that this observer is particularly robust.
