Definitions
- the present invention relates to the steering torque of a hybrid vehicle, according to the demand expressed by the driver by depressing his accelerator pedal.
- a method for generating the torque setpoint of a powertrain (GMP) from the depression of the accelerator pedal of a hybrid vehicle comprising on the one hand an engine thermal traction connected to the kinematic chain of the vehicle by a sliding clutch operating sliding between an open position where it transmits no thermal power, and a closed position where it transmits the full power of the engine to the driveline, and on the other hand an electric traction machine transmitting directly all of its power to the kinematic chain of the vehicle.
- GMP powertrain
- Driving pleasure is a very important factor in the driver's assessment of the vehicle. That is why one of the main goals of automotive control systems is to make the powertrain reactions enjoyable.
- One of the other services offered by a hybrid vehicle is the possibility to provide more torque to the wheel, than with a single engine, by assisting with the electric machine. This is called the electric "overtorque".
- the multiplicity of mechanical architectures of a hybrid vehicle forces car manufacturers to modify their controllers. In a vehicle equipped with a heat engine, the will of the driver is generally translated into a reference regime / torque. However, when the drivetrain of a hybrid vehicle is not closed (clutch cut of the engine open or sliding), the interpretation of the depression of the pedal in iso-power is impossible to translate in a reference Couple wheel / vehicle speed. In a hybrid vehicle, it seems preferable that the driver will be translated directly to the vehicle in its entirety, in a frame of reference (Force / Speed).
- the present invention aims to benefit from the behavior of a conventional vehicle in the neutral and take-off phase, while enjoying the benefits of an interpretation of the driver will in a force / speed reference for a hybrid application.
- the depression of the accelerator pedal is interpreted alternatively in power demand in first reference (Ref-A) torque depending on the speed of an actuator, or in force demand, in a second reference (Ref-B) of force as a function of the speed of movement of the vehicle.
- the regime considered is that of the engine.
- the first repository is preferably used for low speeds, and when the kinematic chain of the vehicle is open, and the second repository is used for higher speeds, and when the driveline of the vehicle is closed.
- This method of preparation ensures a pleasant management, and repeatable, takeoff, neutral and parking.
- FIG. 1 illustrates the interpretation of the pedal in Torque / RPM (Ref-A)
- FIG. 2 illustrates the pedal interpretation in Force / Speed (Ref-B)
- FIG. 3 presents an architecture of principle
- FIGS 4A and 4B illustrate the impact of the transition, depending on the speed at which it is operated.
- a reference Force / Speed also called “vehicle reference”.
- the interpretation of the driver's will is independent of the number and location of the torque actuators.
- the driveline of a hybrid vehicle is not closed (clutch cut of the open or sliding heat engine)
- the interpretation of the depression of the pedal in isopower is impossible to translate in this reference system.
- the controller associates a mechanical power to be provided by the GMP at the level of depression of the accelerator pedal. In the reference frame A, this power is translated into torque reference, in according to the speed of the actuator. In this way, the behavior of the vehicle becomes independent of the current state of the actuator, or the engaged gear ratio, and the vehicle speed becomes easier to control.
- Figure 1 illustrates from an example the interpretation of the pedal in the repository by a set of torque / speed curves for different levels of depression of the same accelerator pedal.
- the engine speed is always greater than 0 when the engine is on.
- the subject of the invention is a method for generating the torque setpoint of a powertrain (GMP) from the depression of the accelerator pedal of a hybrid vehicle.
- the vehicle concerned comprises, on the one hand, a traction heat engine 1 connected to the kinematic chain of the vehicle by a sliding clutch operating slidably between an open position where it does not transmit any thermal power, and a closed position where it transmits all the power of the engine to the drive train, and on the other hand an electric traction machine 4 directly transmitting all of its power to the drive train.
- the invention proposes to use the Ref-A for low speeds, and when the kinematic chain is open, and the Ref-B for the higher speeds, with the closed driveline.
- This method provides in particular that the depression of the accelerator pedal is interpreted alternately in power demand in first reference (Ref-A) torque depending on the speed of an actuator, or in force demand, in a second reference frame (Ref-B) of force as a function of the speed of movement of the vehicle.
- the regime considered in the reference system is that of the engine.
- the first repository is used for low speeds, and when the clutch cutoff is open, and the second repository (Ref-B) is used for larger speeds, and when this clutch is closed.
- the transposition between the two reference systems is direct, when the speed of the engine is proportional to that of the vehicle speed. It's the case when the gearbox is not in neutral, and the clutch is closed. There is then a fixed gear ratio between the traction member and the vehicle wheel. On the other hand, during the takeoff phases (open or sliding coupler), or when the engine is not connected to the wheel (closed coupler and neutral gear), the transposition is no longer direct. It is then necessary to develop particular strategies, to pass from one to another.
- the block diagram of Figure 3 shows a hybrid vehicle (GMP).
- GMP hybrid vehicle
- This GMP comprises, on the one hand, a traction engine 1 connected to the kinematic chain of the vehicle 2 by a sliding clutch 3 operating between an open position where it transmits no thermal power, and a closed position where it transmits all the power of the heat engine to the driveline, and on the other hand an electric traction machine 4 directly transmitting all of its power to the driveline 2.
- Hybrid GMPs like that in Figure 3, have at least two actuators (heat engine and electric machine) capable of producing torque to the wheel.
- a law of energy management determines the optimal distribution in consumption, between the two actuators. Its goal is to reduce consumption, while respecting the torque demand at the wheel, made by the driver.
- the reference systems A engine torque, engine speed
- B wheel force, vehicle speed
- the reference systems A engine torque, engine speed
- B wheel force, vehicle speed
- the change of reference is carried out only for the fraction of power demanded by the driver, which is provided by a traction member connected to the wheel by a coupler, such as the clutch cutoff 3 of the figure 3.
- P Ref represents the share of the total power, passing through the clutch. It is therefore the power to be processed by the change of reference.
- Another aspect of the proposed method is to manage the transition between the two repositories. This is the stage to determine the best time to switch from one repository to another. For this, the invention distinguishes two phases.
- this transition is done, so preferably when the vehicle speed is greater than or equal to a reference speed V-ref.
- the reference speed V-ref is preferably below which, it is not possible to close the clutch cut, otherwise stall the engine. It corresponds to the junction between the interpretation of the accelerator pedal in power demand (iso-power), and in force demand (iso-force). If the transition is made before reaching the reference speed, we have a power discontinuity at the wheel.
- the first reference system (Ref-A) is used when the position of the vehicle lever is at Neutral (Neutral) or Parking, as well as during the takeoff phase of the vehicle from the stop, we use the first: then we switch from the first reference (Ref-A) on the second reference (Ref-B) when the speed of the vehicle increases, and the clutch closes gradually.
- the start of takeoff is done in the Ref-A, which is capable of operating in iso-power, whatever the speed of the vehicle.
- the driver request P-Driver 50kW is respected:
- P-Vehicle P-Driver.
- the reference speed V-Ref adopted for each vehicle depends on the characteristics of the vehicle. It can be modulated by calibration, in order to be as small as possible. The lowest speed for V-ref, is that below which it is not possible to close the clutch, under penalty of stalling the engine. V-Ref depends on how the Ref-B is mapped. It corresponds to the speed of junction between the iso-force interpretation of the pedal, and its iso-power interpretation.
