Definitions
- the invention relates to a method for controlling a motor vehicle torque transmission system and a corresponding control system.
- the invention relates more particularly to the implementation of such a method during the take-off phase of the vehicle, that is to say from the moment when, the speed of the vehicle is no longer zero or low, the transmissions begin to transmit torque to the wheels, until the transmission system is closed, a report being engaged, but not limited to.
- control methods, or control systems for torque transmission systems are already known.
- document FR-2,731,661 describes a method of controlling a torque transmission system which makes it possible to obtain a targeted acceleration of the vehicle during start-up.
- the method comprises:
- the torque transmitted by the transmission system thus allows for a shorter period (duration of the second phase) to reduce the engine speed and slippage of the transmission system, reducing the thermal load of the latter.
- EP-0 707 998 discloses a controlled clutch control device intended to limit the deterioration of the clutch performance due to too high a rise in temperature, and to prevent an excessive fall in the engine speed when the transmitted torque is more important than the motor torque.
- the control of the sliding of the transmission system is achieved by applying a lower torque setpoint transmitted by a predetermined amount to the engine torque, as long as the primary speed is lower than the engine speed.
- This predetermined amount corresponds to a desired acceleration of the engine which should allow the engine speed to increase while the primary speed increases to the engine speed.
- a second torque transmission setpoint is applied, greater than the engine torque so that a deceleration of the engine is controlled.
- the engine speed is then measured to prevent it from going below a threshold value. If the primary speed does not reach the engine speed, the transmitted torque setpoint is determined so as to increase the primary speed and to reduce the engine speed.
- a third phase begins when the engine speed reaches the threshold value, the transmitted torque is then equal to the engine torque in order to maintain a high engine speed.
- This solution has the disadvantage of managing only the engine speed by the transmitted torque, so that only the engine speed is controlled and not the speed and acceleration of the vehicle. Thus, the driver's first wish, namely control of speed and acceleration is not taken into account.
- the transmission system is protected only posteriorly by measuring a sliding time duration
- a first object of the invention relates to a method for controlling a torque transmission system of a motorized motor vehicle, the transmission system being controlled by actuators, characterized in that it is repeated with time intervals At determined the following sequence of operations: - (a) we determine:
- the first torque setpoint aims to ensure the approval of the driver in terms of acceleration, while the other two torque setpoints transmitted serve to limit this first setpoint in order to minimize the thermal stress on the transmission system and to control the engine.
- the approval of the driver is better respected than in the prior art because the first torque set slaves the output speed of the transmission system, not the engine speed.
- good control of the engine is obtained through the control of the engine speed by the second and third instructions.
- the approval of the driver is also improved because the different instructions are recalculated at each time interval, so that the final torque setpoint obtained can take in account sudden changes in the driver's will, and that the speed of the vehicle increases at the same time as the engine speed.
- the first torque setpoint transmitted is determined by carrying out the operations consisting in: determining an output regime setpoint of the transmission system as a function of information representative of the acceleration desired by the driver,
- the determination of the output speed setpoint comprises the operations of:
- the second and third torque setpoints transmitted are determined according to a regulation of the actual engine speed around a maximum engine speed setpoint, and a minimum engine speed setpoint respectively.
- the maximum engine speed setpoint is determined in order to avoid a rise in the engine speed and to reduce the noise generated by the engine, while the minimum engine speed setpoint is determined so as to avoid a too great reduction in the engine speed which could to stall the engine.
- the second and third torque setpoints transmitted are equal to the sum of the actual engine torque and a transmitted torque calculated as a function of the difference between the actual engine speed and the maximum and minimum engine speed setpoints respectively.
- a first predetermined value is subtracted, respectively a second predetermined value is added, at an optimum engine speed determined so as to limit the slip between the engine speed and the engine speed. output of the transmission system.
- the engine speed thus remains permanently close to this optimum value so that the thermal stress of the transmission system is controlled effectively continuously.
- this calculation method makes it possible to prevent the engine from stalling and to control the acoustics for the driver's pleasure.
- the optimum engine speed is equal to the minimum speed corresponding to the torque transmitted, or the power, desired (e) by the driver, determined (e) based on information representative of the acceleration desired by the driver.
- This transmitted torque is for example calculated from the position of the accelerator pedal, the dynamics of the pedal and the gradient of the position of the pedal.
- the torque transmission system is controlled by the fourth torque setpoint transmitted during the entire duration of takeoff, this setpoint being recalculated at each time interval
- FIG. 2 represents a flow diagram of the operations of an exemplary embodiment of the control method according to the invention
- Figure 3 is a graphical representation of engine speeds and output of the transmission system as a function of time during take-off of the vehicle
- FIG. 4 is a graphical representation of the transmitted torque setpoint applied to the actuators of the transmission system as a function of time during the take-off of the vehicle.
- Figure 1 shows a motor vehicle comprising a motor 1 which transmits a torque through a torque transmission system 2 to the wheels 3 of the vehicle.
- the torque transmission system concerned may be a single or dual controlled clutch, dry or wet.
- the control system of the transmission system 2 comprises:
- the control unit 8 is connected to the different sensors 4, 5, 6 so as to receive their signals, and connected to the actuator system 7 so as to control the transmission system 2.
- the control unit repeats at intervals of time At determined the following sequence of operations:
- the operations (i), (ii), (iii) are performed substantially simultaneously by the control unit 8.
- a first torque setpoint transmitted Ci is then calculated in block 15 as a function of this difference. This setpoint makes it possible to adjust the actual output speed N 5 to the setpoint output speed N sc . This first set point Ci will then be processed in block 11 described below. 2. Determination of second and third transmitted torque setpoints C 2 and C 3
- this engine speed setpoint N mc is processed in two blocks 18 and 19, preferably substantially simultaneously.
- n is useful to note that this regulation corresponds at the generation of a minimal transmitted torque setpoint varying around the engine torque, in particular when the engine has reached its target speed, ie the optimum speed plus the predetermined value (N mc + ⁇ Ni), and in the case where the regulator does not contain any integral action, the minimum torque setpoint C2 is directly equal to the engine torque.
- Block 191 represents the calculation of the difference between the engine speed setpoint (N mc - ⁇ N 2 ) and its measurement by the sensor N m : ((N mc - ⁇ N 2 ) - Nm). This difference is then used at block 192 to determine the control value N C om2 of the transmitted torque to reduce this difference, to which is added the disturbance of the engine torque C m .
- N C om2 the control value of the transmitted torque to reduce this difference, to which is added the disturbance of the engine torque C m .
- the operations of the first 9 and second 10 regulators are preferably carried out simultaneously during each of the time intervals ⁇ t of the vehicle take-off phase. Thus, for each of these intervals ⁇ t, the first, second and third transmitted torque set Ci, C 2 , C 3 are determined. These instructions are then processed in block 11 in which a fourth transmitted torque setpoint C 4 is calculated.
- the fourth transmitted torque setpoint C 4 is equal to the minimum value between the maximum transmitted torque setpoint C3 and the maximum value of the first torque setpoint Ci and the minimum transmitted torque setpoint C 2 .
- the control unit 8 sends a control signal to the actuators 7 so that the torque transmitted by the transmission system is substantially equal to this set point C 4 .
- this control signal is sent at the end of each time interval ⁇ t during the whole time of the take-off of the vehicle. This interval is preferably chosen regular and of the order of a few milliseconds so that the control unit can take into account sudden changes in driving due to the driver or the state of the road.
- the torque setpoint C 4 is equal to the torque minimal C2.
- the minimum torque set point C2 allowed the engine speed to remain in a zone defined as acceptable ((N mc - ⁇ N 2 ) ⁇ N m ⁇ (N mc + ⁇ Ni)). Without this instruction, there would have been a much larger motor flight.
- the regulation described above thus makes it possible to ensure closing of the clutch, that is to say to perform the take-off and not to coast and to control the engine speed so as not to stall the engine. motor or not to undergo a soaring diet.
- the invention is not limited to the example of determining the different instructions Ci to C 4 , which can be determined differently.
- the control system for the implementation of the method can then also be different.
- Another arbitration of the three setpoints Ci, C2 and C3 can also be performed, provided that the final torque setpoint C 4 is between the minimum torque C2 and maximum C3 setpoints.
