- the first axle for example the front axle or the rear axle
- the second axle for example the rear axle or the front axle
- the transmission system has the following three modes of operation:
- This third mode of mode "4 * 2" corresponds to a so-called “open” coupler, that is to say that the coupler is deactivated or that it transmits only a negligible amount of torque.
- the coupler may be of the friction type, that is to say it has friction discs intended to come into contact with each other to transmit the torque and an actuator means to discard or bring these discs in contact with each other.
- This actuator means is controlled by the computer 12.
- the coupler may in particular be a multi-disk clutch driven current.
- the control system 60 preferably comprises a first module 61 collecting different information internal and / or external to the transmission system, in particular the vehicle speed, the temperature of the coupler, is the state of the means of transmission mode selection commands, malfunction information of certain equipment and activity information of some computers. This information is then processed in the computer 12, then information signals, for example visual and / or sound, are then emitted by an information means 63 to the attention of the driver. As represented in FIG. 3, the computer 12 implements several modules.
- a first module 64 filters and processes the information received by the computer.
- a second module 65 uses this information to interpret the will of the driver and to determine the operation of the transmission system to be implemented and a third module 66 determines, according to the conclusions of the second module, the information to be transmitted to the driver. driver's attention.
- a first block 67 codifies information to be transmitted to the driver
- a second block 68 manages the interpretation to be made of the state of the control means for selecting the transmission mode
- a Third block 60 manages an operation authorization of the transmission system in a particular transmission mode.
- a V_Failure_Class signal represents the possible fault categories of the 4x4 transmission system or the vehicle. For example, this signal can take values between 0 and 3 where 0 identifies the absence of serious defect and 3 identifies the most severe defects.
- a table below shows the correspondences between the signal value and the severity of the faults.
- the V_Failure_Class signal is generated by a set of dysfunctional detection functions of the 4x4 functional model. It can be constructed either from a measurement, a calculation or simply by a simple algorithm that synthesizes the state of one or more other status or value signals. Depending on the nature of the problem identified, an impact classification of the 4x4 function is assigned to it and therefore assigned a value.
- a two-component Ignition / MOS signal represents the operating state of the vehicle and the computer 12. More precisely, it specifies the various waking states of the computer. Tables below indicate different possible values for these components.
- An output signal V_flag_x_MMILed makes it possible to encode information to be restored to the driver via the man-machine interface, in particular via a means of display and / or sound thereof, such as an element of the dashboard of the vehicle or a loud speaker.
- This signal is formatted with the input signals mentioned above: V_Failure_Class containing information from malfunctions and Ignition / MOS containing computer and / or vehicle wake-up status information and with additional input signals.
- the shaping of this signal is for example carried out by means of a table 50 represented in FIG. 7. This table translates, for example, a state matrix with 4 inputs allowing all the possible combinations.
- V_Failure_Class signal makes it possible to adjust the signaling in the passenger compartment from one or more levels of failures with or without progressivity of the evolution of these levels.
- the signal V_flag_x_MMILed thus makes it possible to adapt to the situations and to raise in the cockpit a visual or sound signaling appropriate. This can be seen, for example, in the case of a signal indicating a serious fault by an audible warning and / or the flashing or no indicator light in the cockpit or on the dashboard of a service key.
- the Ignition (Vehicle Ignition) signal representing the waking state of the system indicates, for example, that if the vehicle is not ready, the instrument panel should not display anything during the initialization or shutdown phases.
- the use of the Ignition and / or MOS signals to format the V_flag_x_MMILed signal can make it possible to manage the reproduction of information in the habitable space, for example the display on the dashboard of light-emitting diodes.
- the computer is not necessarily asleep as the rest of the electrical and / or electronic systems.
- the output signal V_flag_x_MMILed is a function of the signal V_flag_x_DriverDemand translating the transmission mode request formulated by the driver.
- the information to be returned to the driver and its mode of transmission request is complementary, it is voluntary to apply a certain redundancy so as to lock the return of current transmission mode information in the passenger compartment in order to remove any ambiguities. and to respect a specification in case of modification of the construction of the V_flag_x_DriverDemand signal. This redundancy or dependence contributes to the robustness of the driver's information function.
- control method it is possible to lock the operation of the transmission system in the operating mode "4 * 4 All Terrain" of the transmission device.
- This possibility may be present while the control button of the operating modes of the transmission system comprises a pulse operation, that is to say that each pulse on the control button allows the transition from an operating mode to a other.
- the "4 * 4 All Terrain” mode "Is memorized and kept if the driver puts the ignition back on and then restarts in the TLock-Latch seconds after the previous contact cut.
- the duration TLock-Latch is adjusted during the development and must be greater than the time necessary to restart the engine after calibration and represents the time threshold of an engine stall or a temporary break of the contactor really voluntary and which does not carry any ambiguity of this will. For example, the TLock-Latch duration is 30 seconds. If the contact remains off after this time, the system starts in "4 * 4 Automatic” mode considering that it is a different driving phase. The driver must therefore select the "4 * 4 All Terrain” mode again with the control knob.
- the function takes advantage of the fact that the computer takes a certain time before switching off electrically after switching off the switch for reasons of safety and / or preservation of the mechanical components. We can for example use this time to calculate their temperatures rather than measure them and wait for a cooling of these organs.
- the calculator only goes off after a minimum time (determined during the development phases) but possibly variably higher for the previous reasons. For the example, it can be said that this minimum electrical break time is 120 seconds.
- the function allows to keep in memory the last selected selection mode for a certain time, TLock-Latch, if there is a break in the contactor. This allows for example in case of engine stall, to turn off and on the ignition without losing the memory of the previous transmission mode, avoiding confusion and improving the comfort of the user.
- control method according to the invention it is not possible to keep the operating mode "4 * 4 All Terrain" beyond a first speed threshold. Indeed, beyond this first speed threshold, it passes immediately and possibly permanently (except specific action of the driver) mode "4 * 4 Automatic".
- the control method according to the invention may be such that after exceeding a second speed threshold (less than the first speed threshold), this overshoot during a time, especially an uninterrupted time, preferably between 30 seconds and two minutes, for example 50 seconds, the process of command imposes a transition to operating mode "4 * 4 Automatic" as before.
- a logical branch 52 it tests, for a certain duration, if the vehicle speed (measured or calculated) is greater than the second limit speed.
- This duration P_tng_s_LockHoldTime can for example be set at 50 seconds.
- the second threshold speed is set for example at 50 km / h. Indeed, such a speed threshold can be considered as moderately high but over the duration not compatible with the "4 * 4 All Terrain" mode, ie off-road crossing.
- V_Failure_Class is greater than or equal to 1.
- V_Failure_Class is of level lower than 1 (logical branch 58).
- the DriverDemand signal reflecting the operating mode of the transmission system is dependent on the V_Failure_Class signal representing a category of failure or problem of the transmission system 4x4.
- the control method according to the invention takes control over the control button for selecting the operating mode of the transmission system.
- the "4 * 2" operating mode can be active while the driver requires the operating mode "4 * 4 Automatic” or "4 * 4 All Terrain”.
- control method may for example only allow the modes “4 * 2" and “4 * 4 Automatic” and prevent the use of the mode “4 * 4 All Terrain ".
- the control method according to the invention integrates into a transmission system whose hardware architecture:
- - includes at least one control button for selecting the operating modes of the transmission system
- a display of sound or visual mode output as for example a LED display on a dashboard.
