Definitions
- the present invention relates to the field of robotized gearboxes.
- It relates to a method of controlling the position of a clutch on a robotized gearbox for a vehicle equipped with a thermal powertrain (GMP).
- GMP thermal powertrain
- this invention relates to a method for controlling the movement of a clutch control element by an irreversible actuating system composed of an electric actuation motor connected by mechanical transmission means to an element of clutch control, by sending to the electric motor a reference voltage.
- control of the clutch is provided by an electric or hydraulic control system controlled by a computer.
- the control system is most often composed of an electric actuating motor, and a system for transmitting motion towards a clutch rod or cable.
- the motion transmission system between the electric actuating motor 1 and the clutch may be composed, without limitation, according to FIG.
- a set of pinions 3 for transmitting the movement of the motor to a parallel axis
- a screw-nut system 4 which transforms the rotational movement of the parallel axis into a translation movement
- an assistance spring 5 which stores the energy when the clutch closes, and which restores it, helping to open the clutch.
- the technical difficulty encountered is to move the clutch cable with an accuracy of 0.005 mm, without exceeding, despite the lack of knowledge of the effort that must be applied by the electric motor to overcome friction.
- the present invention is to make the transmission phase of the engine torque to the gearbox as transparent as possible for users, that is to say, minimizing torque surges.
- the desired static precision which is 0.005 mm
- the objective is to implement in a original control law, a strategy that ensures the movement of the cable of the clutch with an accuracy of 0.005 mm, without position overruns.
- the invention proposes to limit in amplitude the calculated voltage signal to minimize the difference between the position of the control element and its reference position, when this difference is greater in absolute value than the desired accuracy on the reference position at the end of the trip.
- the calculated voltage signal is saturated with the maximum or minimum voltage of the electric motor, if it is not between these two values.
- FIG. 1 is a diagram of an actuating device
- FIG. 2 illustrates the torque variations of a clutch control actuator
- FIG. 4 shows the evolution over time of the position of the clutch and its reference
- FIG. 5 shows the evolution of the reference voltage of the actuator.
- T d Resisting torque of the electric motor (unknown exogenous input, considered as a disturbance);
- R Resistance of the armature of the electric motor
- L Inductance of the armature of the electric motor
- T d f (pc) is a function of the position of the clutch cable. It depends on the force applied by the screw-nut system 4, the force of the return spring 5 and the force applied by the diaphragm of the clutch.
- the actuator of FIG. 1 has sensors which make it possible, with certain calculations, to measure the position x (between two stops: open and closed position) and
- the objective of the control is to move the clutch cable from an initial position x, to a reference position x re f, to satisfy the conditions of a perfect shift in the gearbox.
- this displacement is implemented by applying to the actuating motor a reference voltage U ref , according to a control method, which can be broken down into four main steps.
- an irreversible actuation system composed of an electric actuation motor connected by mechanical transmission means to the clutch control element.
- this method is based on sending to the electric motor, the reference voltage U ref determined on the basis of a voltage calculated ijc to minimize the difference ⁇ between the position x of the control element and the reference position x ref r referred to end of displacement.
- a first step consists in producing a first voltage signal calculated j jcal c , which is saturated on the maximum voltage U max or minimum U max of the electric motor, if it is not between these two values.
- ⁇ ⁇ represents the error of tolerated position relative to the reference, or interval tolerated in the position around its target, a is a reduction coefficient applied to the calculated voltage jjca ⁇ c ⁇ e] _ f has a ç 0n following.
- the calculated tension is weighted by the coefficient calibrated to greater than or equal to 1.
- the signal then takes values equal to the ratio of the maximum voltages U max and minimum voltages CF 1 "of the traction machine to a calibrated limiting coefficient a.
- the values U max / a or U m i n / a determine the usable voltage range for moving the clutch control.
- a second step is to set the calculated voltage signal U calc .
- a third step is to add an integrated term to the signal U ⁇ alc , if the position difference ⁇ lies between - ⁇ ⁇ and ⁇ ⁇ .
- the calculated voltage u calc 'U calc * is corrected by integrating the difference ⁇ with a calibrated gain K ⁇ non-zero, when this difference is smaller in absolute value than the precision ⁇ ⁇ .
- This originality of the invention is based on the activation or the deactivation of the integration of the difference ⁇ (multiplied by the calibrated gain K ⁇ ), when this difference is smaller in absolute value than the precision ⁇ ⁇ . If
- a fourth phase is to monitor the corrected signal U calc ** in a saturator, to see if this signal is between the values U min and U max . If it is not the case, the Boolean G of the saturator is equal to 1, and the integrator is blocked. This so-called "anti-wind-up" loop makes it possible to suppress the integration term to saturate U calc ** . Thanks to this measurement, the reference voltage U ref from the limiter is always between the maximum voltage values U max and minimum CF 1 "of the electric motor 1. In conclusion, the strategy proposed makes it possible to reduce the position difference very quickly to reach an accuracy of approximately 0.005 mm, without exceeding position. This result is highlighted in FIGS.
