Definitions
- the invention relates to the automatic control of powertrain units (GMP) of a motor vehicle already having a "normal” mode, a “freewheeling engine” (or “sailing idle”) mode, and a function of shutdown and automatic restart of the engine, called “start and stop”.
- GMP powertrain units
- a power train consisting of a heat engine coupled to an automatic transmission having at least one clutch cutoff between the engine and the wheels of the engine.
- a vehicle by exchange of inter-system instructions between an engine computer and a transmission computer, with a view to leaving a normal mode of travel by shutting off the engine when approaching the stop, or by opening the engine clutch to enter a coasting mode with the engine running.
- the "Stop and Start” function makes it possible to stop the engine at 0 km / h, on the brake.
- the purpose of moving the engine freewheel, or “sailing idle”, is to decouple the transmission from the engine, in order to have a vehicle coasting with a motor at idle speed.
- Publication FR 3,030,423 discloses a method of automatic control of a motor vehicle for the transition from a "normal” mode to a "freewheel” mode.
- the vehicle concerned comprises an engine capable of providing torque to the drive wheels, via an automatically controlled clutch.
- the drive wheels of the vehicle are coupled to the engine by the clutch in "normal” mode, or decoupled from it in "freewheel” mode.
- a transition phase is interposed chronologically between the "normal” mode and the "freewheel” mode.
- the engine speed is automatically controlled so that the shaft driven by the clutch rotates at the same speed as its driving shaft, without transmitting torque to the wheels before opening. the clutch, instead of being placed directly on its idle speed.
- This transition period avoids a jerk, when opening the clutch, or if braking causes the return to "normal" mode by closing the clutch suddenly. Moreover, the triggering of this transition step is postponed, if the demand for coasting occurs when the gearbox is in the process of changing state.
- the exchange of information and instructions between the engine computer, and that of an automatic transmission ensures the desired consistency between the behavior of the engine on the one hand, and that of the gearbox with its clutch on the other hand, to manage the transitions between a "normal” mode and a freewheel mode of the "salllng idle” type, where the engine is placed on its idle.
- the aim of the present invention is to build a new inter-system information exchange within the GMP, which makes it possible to reduce fuel consumption, as well as C02 emissions, by extending stop and start modes. and "sailing idle", by other modes of operation.
- the inter-system instructions include performing a motor shutdown, on the one hand in normal high-speed movement when releasing the accelerator pedal with the foot on the brake, and on the other hand when coasting with the accelerator and brake pedals released.
- the sending of inter-system information from the ECM to the ATCU includes a request for preparation of the automatic transmission at the opening of the clutch and the management of the engine torque, the demand for freewheeling with the engine running on its idle, and the demand for freewheeling with the engine off.
- FIG. 1 groups the states of the GMP
- FIG. 2 describes the "coasting stop high speed” function, or "stop disengaged at high speed"
- FIG. 3 shows the inter-system exchanges associated with this function
- FIG. 4 describes the "sailing stop” function, or "motor freewheel stopped”.
- FIG. 5 shows the inter-system exchanges associated with this function.
- the automatic control of state changes illustrated in FIG. 1 relates to a powertrain (GMP) composed of a heat engine coupled to an automatic transmission having at least one clutch breaking between the engine and the wheels of a vehicle.
- the automatic control of these changes of states is effected by exchanging inter-system instructions between an engine calculator (ECM) and a transmission computer (ATCU). These exchanges make it possible to leave a normal mode of travel, by shutting off the engine when approaching the stop, or by opening the clutch in order to enter a freewheeling mode with the engine running. This displacement commonly called “sailing idle” is done with the engine running on its idle speed.
- Figure 1 also highlights new features introduced to extend GMP inter-system information exchange, managing a "normal” mode and a “free idle” or “sailing idle” mode. These two modes are associated with other states, intermediate or complementary, to combine the advantages of the freewheel function and the possible shutdown of the engine.
- a new function, called Coasting Stop High Speed, for "stop disengaged at high speed”, is planned. From the "normal” mode, it allows the engine to stop at about 20km / h, when the accelerator pedal is released, with the foot on the brake. Under these circumstances, the engine computer stops the engine to save fuel.
- the diagram shows two other states where the motor can be cut:
- the inter-system instructions exchanged include performing a motor cut-off, firstly in normal high-speed movement when the accelerator pedal is released with the foot on the brake, and on the other hand when coasting with the accelerator and brake pedals released.
- Sending inter-system information from ECM to ATCU now includes a request for the preparation of the automatic transmission when the clutch opens and the management of the engine torque, the demand for freewheeling with the engine running on idle, and the demand for freewheeling with the engine cut.
- the entry and exit of the coasting stop high speed mode, or the "high speed disengaged stop", from the "normal” mode, are illustrated in figure 2.
- This function corresponds to a stopping of the engine at approximately 20km / h , with the accelerator pedal released, and the foot on the brake. It allows the stopping of the engine, in order to gain more fuel.
- the use case concerned is for example the arrival on an obstacle or an event (red light type, roundabout), where the driver releases the accelerator, and begins to brake.
- the figure shows the evolution over time of pedal position accelerator, engine speed, clutch, and GMP coordinator.
- the application for authorization to cut the engine at high speed to slow the vehicle coasting with the engine off is sent by the ECM to the ATCU, when the engine is idling, with the accelerator pedal is fully released and the brake pedal is depressed.
- the automatic transmission In order to ensure a subsequent restart under the best conditions, the automatic transmission must pre-engage the optimal ratio depending on the type of engine stop requested, "auto stop”, “coasting stop high speed” or “sailing stop”.
- a specific "inter-system”, summarized in figure 3, is set up between the ECM and the ATCU for the passage between the "normal” mode and the "coasting stop high speed” mode.
- the ECM sends the request "ICE StartStopStatus" to the ATCU, to express its desire to stop the engine.
- the ATCU sends back an "AT StartStopMode” message to the ECM, to respond positively to this request when the transmission is correctly predisposed.
- the request "ICE StartStopStatus” is sent on the date tl, with the accelerator pedal fully released, the brake pedal pressed, and the engine idling.
- ATCU authorization "AT StartStopMode” is sent to engine on the date t2, when the transmission is predisposed for the next restart of the engine.
- the request for authorization to shut down the engine at high speed for a high speed disengaged stop is sent by the ECM to the ATCU, when the engine is idling, with the accelerator pedal fully released. , and the brake pedal pressed.
- the “sailing stop” function illustrated in Figure 4 corresponds to an extension of the "sailing idle”, by cutting the engine to optimize consumption, once the automatic transmission decoupled from the engine.
- the request for authorization to stop the engine to enter the coasting phase is sent by the ECM to the ACTU in the absence of braking.
- a specific inter-system summarized in figure 5, is set up between the ECM and the ATCU.
- the ECM sends its willingness to freewheel ATCU with a request entitled “ECM SailingRequest”. It sends an authorization request to stop the engine with another request called "ICE StartStopStatus”. Then the ATCU authorizes the stopping of the engine with the message "AT StartStopMode", and the coasting, with the message "AT SailingRequest”.
- the use case targeted by this example is the following.
- the driver releases the accelerator without braking.
- the ECM expresses its will to enter freewheeling.
- the clutch of the transmission is fully open.
- the accelerator pedal is fully released, and the engine is idling.
- the request for authorization to cut the engine occurs on the date t4. It is granted by ATCU on the date t5.
- Authorization to shut down the engine to coast to coast with the engine off is given by the ACTU to the ECM after the engine speed has dropped to idle.
- the engine shutdown is performed.
- the GMP is in "sailing stop" mode.
- ECM SailingRequest which expresses the will of the engine to place the GMP freewheeling (free wheel request of the engine) can already contain the following states and queries: - the normal default mode: "normal driving”,
- the invention adds to this inter systems, the state "sailing stop" where the vehicle moves with the clutch open, and engine stopped.
- the information sent by the ECM to the CUTA includes a request for the preparation of the transmission to predispose to running in a freewheel engine.
- the invention does not involve any evolution of the "AT SailingRequest" inter systems which already contains the states and queries:
- the three existing states without the new functions can be:
- the inter systems "ICE StartStopStatus" to transmit the type of stop requested to the ATCU, can already contain the following states (in addition to the engine state cut "off"):
- ICE StartStopStatus can additionally contain:
- requests sent by the ECM to ATCU now include:
- the invention can be applied without changing the technical definitions of the GMP. It applies to different types of transmissions, including dual clutch transmission (DCT) and CVT (Continuously Variable Transmission) type drives, while also being expandable to clutch architectures driven from type "e-clutch” (controlled clutch)
- DCT dual clutch transmission
- CVT Continuous Variable Transmission
- e-clutch controlled clutch
- the creation of new inter systems allows an optimal predisposition of the automatic transmission.In informing it of the will to leave the free wheel, it provides a good performance NVH "Noise Vibrations Harshness » The minimization of the shocks, as well as a speed of re-closing of the clutch, and the improvement of the take-off of the vehicle.
