Definitions
- the invention relates to a method and a control system for a motor vehicle with a controlled clutch equipped with an automatic engine stop and restart device.
- This device for stopping and restarting the engine automatically (or "Stop and Go" device according to a terminology commonly used) is primarily intended to reduce fuel consumption, especially in the city at a stop at traffic lights and in traffic jams , and to consequently reduce the pollution of the atmosphere by the exhaust gases of the engine of the vehicle.
- This device is advantageously used in combination with an actuator clutch control, which is associated with a robotized gearbox, an automatic gearbox or a manual gearbox with a clutch pedal acting by electrical connection.
- the clutch control by an actuator requires a determination of the licking point of the clutch, that is to say the point on the most advanced clutch curve in the direction of the clutch for which one does not still transmits no torque, and a follow-up of the evolution of this point, to avoid shocks and jerks in the transmission of the vehicle during the controlled actuations of the clutch.
- the invention particularly aims a method for determining the licking point of a clutch driven in a vehicle equipped with a device for stopping and starting automatic engine of the aforementioned type, this determination being performed in masked time and without degrading the behavior of the vehicle and the comfort of driving.
- It proposes for this purpose a method of controlling a vehicle automobile comprising a clutch controlled by an actuator and a device for stopping and restarting the engine automatically under predetermined conditions, in particular comprising a neutral position of the gearbox, which consists in determining the licking point of the clutch during the the interval of time preceding the stopping of the engine of the vehicle when this stop is controlled by the aforementioned device.
- the method according to the invention therefore takes advantage, to determine the licking point of the clutch, the time interval between the effective stop engine stop order given by the aforementioned device when the conditions wanted are met. This time interval is short, typically about one second, but sufficient to make this determination which, when performed under these conditions, takes place when the vehicle is stopped and does not harm the behavior of the vehicle and the comfort driving.
- this method also consists in determining the licking point of the clutch at each stop of the engine controlled by the aforementioned device.
- the invention also provides for inhibiting or stopping the determination of the licking point if the aforesaid time interval is too short for this determination.
- this method also consists in detecting the position of the licking point of the clutch by detecting the the rotation of a primary shaft of the vehicle gearbox.
- the method according to the invention consists in detecting the point of licking of the clutch by progressive closing of the clutch from its open position, the speed of rotation of the motor being greater than or equal to a predetermined minimum value, and by ré ⁇ opening of the clutch.
- This determination of the licking point is totally transparent for the driver or passengers of the vehicle: it is sufficient indeed, the clutch being open, the gearbox being in the neutral or dead position and the primary shaft of the gearbox being stopped (the vehicle being in principle stopped), partially closing the clutch until detection of the rotation of the primary shaft of the vehicle gearbox after which the clutch is opened again to return to the initial condition.
- the clutch is controlled by an actuator comprising a movable element whose displacement corresponds to the opening and closing of the clutch
- the method according to the invention consists in detecting and recording the position of this movable element of the clutch. actuator when it corresponds to the licking point of the clutch.
- the time interval between the stop command given by the aforementioned device and the actual stopping of the motor is also used to search for the previously recorded value of the licking point of the clutch, or the corresponding position of the clutch. moving element of the clutch actuator, before making a new determination of the licking point. This makes it possible to directly observe the evolution of the licking point.
- the invention also proposes a motor vehicle control system intended for the execution of the method described above, this system being characterized in that it comprises means for detecting and recording the position of an element.
- movable actuator acting on the clutch of the vehicle means for detecting the rotation or the speed of rotation of a primary shaft of the box.
- vehicle speeds and information processing means connected to the aforementioned means of detection and to the aforementioned device for automatically stopping and restarting the engine and programmed to control the actuator in the direction of closing the clutch and for registering the position of the movable element of the actuator corresponding to a rotation of the gearbox primary shaft from a zero rotation, during the period of time preceding the stopping of the engine being driven by the aforementioned device.
- the controlled clutch and the device for stopping and restarting the engine automatically, means of "creeping” (moving the vehicle at a very slow speed) to the release of the brake pedal by the driver, which forces the driver to press this pedal to prevent the vehicle from moving and thus allows the engine to stop, if the conditions are met, by the aforementioned automatic stop and restart device.
- auxiliary means of regulating the temperature of the passenger compartment of the vehicle when the engine is stopped by the aforementioned automatic stop and restart device are also possible, when the vehicle is equipped with an air conditioning device, auxiliary means of regulating the temperature of the passenger compartment of the vehicle when the engine is stopped by the aforementioned automatic stop and restart device.
- auxiliary means it is possible, for example, with these auxiliary means, to constitute a reserve of cold (or hot) when the engine rotates and use this reserve when the engine is stopped by the aforementioned device for stopping and automatic restart.
- means for detecting the position of the vehicle on a hill-side terrain comprising, for example, an inclinometer, for preventing the aforementioned device from stopping the engine if the predicted conditions are met. This avoids the recoil of the vehicle when restarting the engine, which would most often result in a shock or a jerk in the transmission.
- the brake locking means to the aforementioned means for releasing the brakes only after detecting the passage of a torque in the controlled clutch, which prevents the vehicle from backing up hill at engine restart.
- FIG. 1 shows schematically a control system according to the invention
- FIG. 2 is a general flowchart of the various operations of the control method according to the invention.
- the control system according to the invention is intended to equip a motor vehicle comprising an internal combustion engine 10 of a conventional type, the output shaft 12 is connected by a clutch E to an input shaft or primary shaft 14 of a gearbox 16, such as for example a robotized mechanical gearbox, whose output shaft 18 drives the drive wheels 20 of the vehicle via a differential 22.
- the clutch E is driven by an actuator 24, for example of the electrical or fluidic type, comprising a movable actuating element of the clutch.
- the vehicle is also equipped with a device 26 for stopping and restarting the engine automatically or "Stop and Go" device, essentially comprising a reversible alternator-starter controlled by a computer 28 conventionally comprising one or more microprocessors, memories , and input-output interfaces, this computer can also control, inter alia, the actuator 24 of the clutch E and the gearbox 16.
- a device 26 for stopping and restarting the engine automatically or "Stop and Go" device essentially comprising a reversible alternator-starter controlled by a computer 28 conventionally comprising one or more microprocessors, memories , and input-output interfaces, this computer can also control, inter alia, the actuator 24 of the clutch E and the gearbox 16.
- the automatic stopping and restarting device 26 is for controlling the stopping of the vehicle engine 10 to reduce fuel consumption when certain conditions are met, including:
- the gearbox 16 is in the neutral position (or in neutral);
- the rotational speed of the output shaft 12 of the motor 10 is greater than or equal to a predetermined minimum value corresponding for example approximately to the idle speed;
- the vehicle is at a standstill (its traveling speed is zero) or its speed is very low, for example less than 2 km / h. These conditions may also include driver support on the brake pedal.
- a stop command of the motor 10 is given by the computer 28 and causes the actual stopping of the motor 10 with a response time which is typically less than one second. This time interval is sufficient for the search of the licking point previously determined and for a new determination of the licking point, which essentially consists of:
- the detection of the licking point of the clutch E is done without modifying the conditions for stopping the engine 10 by the device for stopping and restarting the engine automatically. If the time interval between the stop command and the actual stopping of the engine is too short to allow a determination of the clutch licking point as indicated, and if the determination is started, this is discontinued. determination and restoring the actuator to the initial position, the stop being given priority over the determination in progress.
- the determination 46 of the licking point of the clutch E comprises the control of the actuator 24, the detection of the rotation of the primary shaft 14 of the gearbox and the recording of the position of the movable element of the actuator 24, then the re-opening of the clutch.
- the next operation 48 is the actual stopping of the engine 10 of the vehicle, which is followed by the restarting of the engine 50 by the device 26, when the driver indicates his intention to restart the vehicle. It is also possible to determine the licking point in other conditions, for example when the engine is started cold, when the driver stops the engine, during all stops, or some of them, by the device. "Stop and Go".
- the stops at which this determination is made are determined according to certain parameters, such as the time elapsed or the distance traveled since a previous determination, the number of actuations of the clutch, the engine temperature (a rise in temperature causing a variation of the licking point due to thermal expansion).
- the invention is applicable to a clutch comprising or not an internal friction wear compensating system, the invention allowing in the first case to monitor the proper operation of the wear-compensating system, for example by giving information by a diagnostic system accessible to a repairer.
